TECHNICAL FIELD
[0001] This invention relates to automated banking machines. Specifically this invention
relates to a system for handling transaction receipts or other sheets being delivered
to a user operating an automated banking machine which avoids producing a sheet which
is unsuitable in size for handling by the machine.
BACKGROUND ART
[0002] Automated banking machines are well known in the prior art. Automated banking machines
may include automated teller machines (ATMs) through which consumers may conduct banking
transactions. Other types of automated banking machines include devices which count
or deliver cash or other items of value to a consumer, bank teller or other user,
as well as point of sale (POS) terminals and other terminals which enable users to
carry out transactions of value.
[0003] It is common for automated banking machines to provide the user with a printed receipt
which documents each transaction. The receipts typically show the type of transaction
and the value or amount involved. Other information may also be included on the receipt
depending on the type of automated banking machine. Receipts may include information
such as the user's name, the time of day, the location where the transaction was conducted
and an account balance. Receipts may also include the user's card number and an account
number of a user's account.
[0004] Often users of automated banking machines are in a hurry and forget to take the receipt
after conducting a transaction. When this occurs the receipt typically remains extending
outward from a receipt delivery opening in the machine until a next transaction is
conducted and another receipt is provided. The subsequent receipt typically pushes
the prior receipt out from the delivery opening and the prior receipt falls to the
ground or on the floor adjacent to the machine.
[0005] In the case of automated teller machines, customers very often fail to take their
receipt. This results in an unsightly litter problem in the area of the machine. The
operators of such machines have to frequently clean up the area to keep it suitable
for customers.
[0006] Failure to take a transaction receipt may also pose other problems. Specifically
receipts may contain information and can be utilized by criminals. This information
may include account numbers and balances which may be used for illicit purposes.
[0007] With the increased acceptance of automated banking machines, it is now often possible
to print more information on transaction receipts. Often this information is of a
private nature which users would not wish to have disclosed. While the provision of
such information is of value to users who consistently take and review their receipts,
consumers who do not run increased risks.
[0008] Systems have been devised for capturing currency and credit or debit cards which
users fail to retrieve from an automated banking machine. However, mechanisms for
retrieving such items are often complex and expensive. Such mechanisms also take up
the limited space available inside an automated banking machine. While such retrieval
systems are justified with regard to items of high value such as currency and credit
and debit cards, such mechanisms have not been justified with respect to receipts.
[0009] There are also different types of receipt forms that have been used in automated
banking machines. Certain machines use pre-printed forms with a predefined format.
Such forms are always the same size when delivered to the user of a banking machine.
Such forms commonly include pre-printed information such as the name of a financial
institution. Such forms include a "top of form" (TOF) indicator which is a mark on
each form which serves as a guide for printing on the forms as well as for separating
the forms. The nature of TOF indicators may vary between form types and suppliers.
As a result, a change in forms may necessitate adjustment of the machine to properly
sense the TOF indicator on the new form type.
[0010] Other automated banking machines use plain roll paper for printing receipts. Generally
the roll paper does not include pre-printed information. The color and quality of
plain roll paper can vary. If the type of roll paper is changed the machine may require
readjustment to properly detect and handle the new type of paper.
[0011] Automated banking machines which handle pre-printed forms with TOF indicators generally
do not handle plain roll paper receipts and vice versa. Therefore an operator of an
automated banking machine is limited to using the form type for which the machine
is made.
[0012] Further problems may arise when the paper supply for the receipt printer or a similar
device in an automated banking machine, approaches depletion. A form sheet related
to a transaction may be cut and delivered to a user, while leaving an insufficient
length of paper to produce another form sheet. Such end pieces are often too short
to be discharged by the printer. When this occurs, the small scrap piece may remain
in the printer or other mechanism and can cause a jam or other malfunction. Such small
scraps of paper may not be readily visible to a person servicing the machine. The
printer and transport mechanism need to be opened and/or taken apart to remove such
paper scraps. At a minimum the printer must be opened to look for such scraps, which
is time consuming. To avoid this problem users of automated banking machines often
replenish paper rolls or other paper supplies before it is necessary.
[0013] Thus there exists a need for a receipt form handling system for an automated banking
machine that avoids the production of form sheets which are of insufficient length
to be handled and which automatically adapts for use with paper of various types.
[0014] JP 62 174 775A discloses a recording process including a sheet sensor adjacent a
sheet roll to prevent images being formed on a sheet that is shorter than a specified
length. The system includes a printer, a drive, a cutter, a sensor, and a controller.
DISCLOSURE OF INVENTION
[0015] It is an object of the present invention to provide an automated banking machine
including a receipt form handling system.
[0016] It is a further object of the present invention that the receipt form handling system
in an automated banking machine senses the approach of an end of a paper supply, avoids
producing a form sheet which has an insufficient continuous length to be delivered
to a delivery area, prevents operation of a cutter for cutting form sheets when an
end of a paper supply is sensed, avoids producing short scraps of paper which can
not be automatically transported, and/or in which the paper supply may be replenished
more quickly.
[0017] It is a further object of the present invention that the system reduces malfunctions
in an apparatus for printing form sheets, can be used to deliver a form sheet to a
delivery area from which the sheet may be removed mechanically or manually, automatically
adapts to different paper types and paper having different qualities, minimises wasted
paper in a supply used to produce form sheets, and/or is reliable and economical to
operate.
[0018] It is a further object of the present invention to provide a method for preventing
production of paper form sheets in an automated banking machine that are too short
to be reliably delivered to a delivery area.
[0019] Further objects of the present invention will be made apparent in the following Best
Mode For Carrying Out Invention and the appended claims.
[0020] According to the present invention, there is provided an automated banking machine
apparatus as recited in Claim 1, and a method of preventing the cutting of paper sheets
in an automated banking machine that are too short, as recited in Claim 11.
[0021] Thus a preferred embodiment to the present invention provides a receipt form handling
system in an automated banking machine which includes a sheet source in an interior
area of the machine. The sheet source delivers a sheet which comprises a transaction
receipt. The source is typically a printer device that prints indicia on the form
sheet responsive to the transactions conducted at the machine. The system also includes
an outlet from which the user may take a sheet that has been delivered.
[0022] The printer is operative to print indicia on paper that extends in a paper path.
The paper path extends from a supply such as a paper roll or stack, to a delivery
area. The delivery area in the preferred embodiment includes a nip through which a
form sheet is pulled into a sheet transport. However in other embodiments the delivery
area may include other types of areas from which a form sheet may be mechanically
or manually removed.
[0023] A drive is positioned in the paper path. The drive engages the paper and selectively
moves it toward the delivery area. A cutter is also positioned adjacent to the paper
path. The cutter is selectively operative to transversely cut the paper in the paper
path. A sensor is positioned adjacent to the paper path. The sensor senses the presence
of the paper at a location that is upstream in the path from the cutter.
[0024] A controller is operatively connected to the cutter and the sensor. When the sensor
senses paper at the location the controller operates to enable the cutter to cut the
paper at the end of each form sheet which is printed. However responsive to the sensor
ceasing to sense paper at the location, which indicates that an end of the paper has
moved downstream of the location, the controller ceases operation of the cutter. This
avoids cutting a form sheet which is of insufficient length to be moved by the drive
to the delivery area. It also eliminates the creation of short scraps of paper which
might otherwise remain in the printer.
[0025] A servicer replenishing the paper supply need not be concerned with the possibility
that small scraps of paper which could cause malfunctions may remain in the printer.
The servicer may load a new supply of paper and return the system to service. The
fact that the servicer does not have to open or disassemble components of the system
to inspect for such paper scraps saves time.
[0026] The controller of the preferred embodiment of the present invention is adapted to
enable handling receipt form sheets of the pre-printed variety which include a top
of form (TOF) indicator, as well as plain paper receipts. The preferred embodiment
is also self-adjusting to accommodate changes in paper color and quality.

BEST MODE FOR CARRYING OUT INVENTION
[0028] Referring now to the drawings and particularly to Figure 1, there is shown therein
an isometric view of an automated banking machine generally indicated 10. Automated
banking machine 10 is an automated teller machine. However, it should be understood
that the present invention may be used in other types of automated banking machines
including currency counting units, currency acceptors, scrip terminals, POS terminals
and similar type devices.
[0029] Automated banking machine 10 includes a fascia 12 which includes a user interface.
The fascia includes an opening through which a screen 14 may be viewed. A screen is
used for providing instructions and delivering messages to the user. The fascia also
has thereon a keyboard 16 through which the user may enter instructions.
[0030] The fascia also includes openings for other types of devices and mechanisms. In the
embodiment shown these include a depository opening 18 into which a user may place
deposits. A currency delivery opening 20 is also provided through which currency is
delivered to the user. The fascia also includes a card entry slot 22 wherein a user
inputs a debit or credit card which is used to initiate operation of the machine.
The fascia also includes a receipt delivery opening 24 through which transaction receipts
are delivered to the user.
[0031] The sheets which comprise the customer receipts are delivered to receipt opening
24 by the transport and retrieval apparatus generally indicated 26 in Figure 2. Apparatus
26 includes a base 28 which is supported in an interior area of machine 10. Base 28
supports thereon a sheet source, which in the preferred form of the invention is a
transaction receipt printer 30 (see Figure 3). Printer 30 is preferably a conventional
type receipt printer which prints receipts on sheets using thermal, dot matrix, ink
jet, laser or other printing techniques. The printer also preferably is fed from a
continuous roll or a fan-fold stack of paper. The printer also preferably includes
a cut-off device for cutting sheets and separating them after the receipt information
has been printed thereon. The present invention may be used to produce receipts of
uniform length or of varied lengths. The preferred embodiment of the present invention
is also specifically adapted for use with either pre-printed type form receipts or
plain paper-type receipts.
[0032] Apparatus 26 further includes a frame 32. Frame 32 is supported and rotatably mounted
on a pair of uprights 34 and 36. Upright 34 supports a drive which includes a motor
38 which is operable to drive a pulley 40 through a belt 42. Pulley 40 in turn is
connected to a shaft 44. Frame 32 is supported on and rotatably movable about shaft
44.
[0033] A pair of pulleys 46 and 48 are mounted on shaft 44. Pulleys 46 and 48 operate to
drive a pair of transversely spaced belts 50 and 52 respectively. Belts 50 and 52
are continuous belts which extend about pulleys 54 and 56. Pulleys 54 and 56 are mounted
on a shaft 58 at an opposed end of frame 32 from shaft 44. As best shown in Figure
12, frame 32 in cross-section includes a lower wall 60. The inside surface of lower
wall 60 includes an upward extending supporting projection 62 thereon. As shown in
Figure 12 a sheet 64 may be transported in engaged relation with lower flights of
belts 50 and 52 and supporting projection 62. This arrangement provides for reliable
transport of sheets with limited controlled slippage.
[0034] As shown in Figure 2, lower wall 60 of transport 32 includes upturned end projections
66 and 68. End projections 66 and 68 include an opening 70 therebetween. Supporting
projection 62 extends downward in opening 70.
[0035] Frame 32 further has supported thereon a roller 72 which serves as a supporting member.
Roller 72 is free-wheeling and is generally engaged with the lower flights of belts
50 and 52. Roller 72 further includes a central recess 74 as shown in Figure 3. Supporting
projection 62 extends downwardly in recess 74.
[0036] A gate member 76 is rotatably mounted in supported relation on frame 32. Gate member
76 is shown in greater detail in Figures 9, 10, and 11. Gate member 76 includes a
pair of slots 78 therein. The lower belt flights of belts 50 and 52 each extend in
a slot 78 when gate member 76 is in the position shown in Figure 2.
[0037] A storage location or bin generally indicated 80 is positioned generally below frame
32 in the operative position of the transport and retrieval apparatus shown on Figure
2. Frame 32 is supported in the operative position by member 82, which is attached
to base 28. As shown in Figure 2, member 82 limits the downward rotation of frame
32 about shaft 44. An electrical switch is provided to sense when the frame is in
the downward position in which the transport is operative to deliver sheets. It should
be further noted that member 82 is configured to direct sheets produced by printer
30 toward the lower belt flights and gate member 76.
[0038] Gate member 76 is shown in greater detail in Figures 9 through 11. Gate member 76
is arcuate in cross-sectional profile and includes an outside surface 86 and an inside
surface 88. Gate 76 includes spaced end walls 90. End walls 90 have inwardly tapered
portions 92.
[0039] End walls 90 further include a pair of outwardly directed shaft projections 94. Shaft
projections are journaled in supported relation on frame 32 and comprise a pivot.
It should be noted that shaft projections 94 are disposed off-center from a center
of the arcs of the inside and outside surfaces. The center of the arcs is schematically
indicated 95 in Figure 11.
[0040] End walls 90 each further include outward extending stop projections 96. The purpose
of stop projections 96 is later discussed in detail. Inside surface 88 further includes
small inward extending projections 98 thereon. Inward extending projections 98 serve
to break surface tension between sheets passing in supported relation with the inside
surface in a manner later discussed. The inward extending projections 98 also keep
the leading edges of sheets from catching on the bottoms of slots 78.
[0041] Gate member 76 further includes a top edge 100. Slots 78 extend transversely through
the inside and outside surfaces of the gate member and terminate at top edge 100.
Top edge 100 is somewhat tapered and thinned relative to the remainder of the arcuate
profile of the gate member as shown in Figure 11. Gate member 76 further includes
a bottom edge 102. Inside surface 88 extends in an arc approximately 180 degrees between
the top edge and the bottom edge. Slots 78 extend in a first portion generally indicated
104 of the outside surface of the gate member. The outside surface also has a second
portion generally indicated 106 which is a smooth, arcuate surface and which provides
low resistance to the movement of sheets thereon.
[0042] It should also be noted that because of the slots 78 and the absence of material
therein, the gate member 76 is biased by gravity to rotate about shaft projections
94 in a clockwise direction from the position shown in Figure 11. This weight distribution
provides a biasing means which is operative to move the gate member in a manner later
discussed.
[0043] The mechanical operation of the invention is now explained with reference to Figures
3 through 7. Printer 30 delivers a sheet 108 which in the preferred embodiment comprises
a transaction receipt form. Printer 30 delivers the sheet 108 upwardly toward the
lower belt flights of belts 50 and 52. Only belt 52 is shown in the Figures for purposes
of simplicity.
[0044] Delivery of the sheet adjacent to the gate member is sensed by a first sensor 110.
First sensor 110 is preferably a photoelectric optical type sensor. First sensor 110
is operatively connected to a controller 112 which is shown schematically in Figure
5. The operation of the controller is later discussed in greater detail with reference
to Figures 13 through 24. Upon the delivered sheet moving adjacent first sensor 110,
controller 112 operates the drive by starting motor 38 to begin moving the lower belt
flight in an outward direction generally indicated by Arrow A. The controller circuit
is connected to a control device for the printer so that the drive begins moving responsive
to operation of the printer having moved the paper an amount sufficient so that the
paper sheet protrudes from the printer sufficiently to engage the belt flights. In
other embodiments the drive may begin moving responsive to the sensor sensing the
sheet moving adjacent thereto.
[0045] Sheet 108 is directed into a delivery area which includes a nip generally indicated
114 formed by the outside surface of the gate member and a downward facing first side
of the lower belt flight. The delivery area is an area from which the form sheet delivered
from the printer may be removed. The moving lower belt flight pulls sheet 108 into
the nip and causes the sheet to engage the area on the outside surface of the gate
member where the belt flight extends through the slot 78.
[0046] As shown schematically in Figure 3, a stop serves to prevent rotation of gate member
76 in a clockwise direction. The stop operates by engagement of the stop projection
96 on the gate member with a surface of the frame. The stop assures that when the
gate member is not being acted upon by a sheet moving in the outward direction, the
gate member is maintained in the first position shown in Figure 3.
[0047] Engagement of sheet 108 with gate member 76 and the lower belt flight of belt 52
causes the sheet to apply a force to the gate member. This force rotates the gate
member in a counter-clockwise direction as shown, to a second position shown in Figure
4. In this second position the sheet 108 is supported between the smooth second portion
106 of the outside surface of the gate member and the belt flight.
[0048] The gate member is preferably freely rotatably movable. Shaft projections 94 extend
in journaled relation in frame 32. The force applied by sheet 108 moves the gate member
to the second position without significant resistance. In the second position of the
gate member, sheet 108 is enabled to readily pass in an outward direction over the
outside surface of the gate.
[0049] It should also be noted that a gap 116 extends between the top edge 100 of the gate
member and the roller 72. This gap is substantially closed as the gate member moves
from the first position to the second position. This closure of gap 116 operates to
insure that sheets passing over the gate member are directed to maintain engagement
with the lower belt flight. The rotation of roller 72 is in a counter-clockwise direction
as shown when the belt flight moves in an outward direction. As a result, any sheets
which tend to maintain engagement with the outside surface of the gate member are
directed against the moving surface of roller 72 and are directed back into engagement
with the belt flight.
[0050] It should be noted that the stop further limits movement of gate member 76 in the
counter-clockwise direction. This is done by engaging the stop projection 96 with
a further surface of the frame as indicated in Figure 4. Thus the stop prevents the
gate member from rotating too far in response to a force applied by the sheet.
[0051] Sheets moving in the outward direction pass the gate member 76. Once the sheets are
no longer engaged with the gate member, the gate member returns to the first position
due to the biasing force of gravity as represented in Figure 5. The sheets pass in
the outward direction along a path which is preferably longer than a sheet length,
until they reach an outlet generally indicated 118. At outlet 118 the sheet is accessible
to the user. As shown in Figure 5 sheet 108 extends outwardly at the outlet through
the receipt delivery opening 24 in fascia 12.
[0052] The drive operates responsive to the controller to move the lower belt with the engaged
sheet in the outward direction until a second photoelectric sensor 120 at the exit
end of the path senses the passage of the inward end of the sheet. Sensor 120 is connected
to controller 112 which operates to stop motor 38, which stops the drive moving the
lower belt flight. The controller then runs the transport in reverse until it again
senses the inward end of the sheet, and then stops transport movement. In this position
the sheet 108 remains engaged to the belt flight and is directed slightly upward by
the end projections 66 and 68, so as to facilitate its removal by the user through
the opening 24. The belt flights allow limited slippage so the user may manually remove
the extending sheet without damage.
[0053] Controller 112 is operatively connected with a timer schematically indicated 122.
Controller 112 preferably includes one or more processors, and timer 112 is part of
a programmed routine executed by a processor as later discussed. Alternatively, the
timer may be resident in another system connected to the controller. In response to
certain programmed conditions later discussed and after a set time, the controller
operates a retract routine to move the drive in an opposed direction such that the
lower belt flight moves in an inward direction as indicated by arrow B in Figure 6.
If the customer has not removed the sheet, the controller operates the drive so as
to retrieve the sheet in a manner hereinafter described. If, however, the user has
removed the sheet 108, the sheet will not be sensed and the controller executes programmed
steps in response to this condition. Subsequently the apparatus is ready to deliver
the next sheet.
[0054] If the user has not removed the sheet when timer 122 reaches the set time, the sheet
continues to be sensed by second sensor 120. In response to programmed conditions
being satisfied controller 112 operates the drive so that the lower belt flight moves
in the inward direction. As a result sheet 108 moves in an inward direction along
the path until it engages the arcuate inside surface of gate member 76. Upon engagement
of the inside surface of the gate member, the sheet is directed in supported relation
thereon into the storage location 80. As shown in Figure 6 as the sheet 108 passes
over the inside surface of the gate member it is turned 180 degrees. The sheet is
also sensed by sensor 110 as it moves adjacent to the gate member 76.
[0055] The controller 112 runs the drive with the lower belt flight moving in the inward
direction for a sufficiently long time and in a manner to assure that the sheet is
moved into the storage location. Upon the sheet reaching the storage location it preferably
lies in a flat position supported on base 24. Because the retrieved sheet is delivered
in a flat orientation, a large number of sheets may be stored in the storage location
80 before the retrieved sheets must be removed. As shown in Figure 7 once the retrieved
sheet has been delivered to the storage location, the transport and retrieval apparatus
26 is ready to deliver and retrieve further sheets from printer 30.
[0056] The removal of accumulated sheets is schematically demonstrated in Figure 8. After
a period of extended operation a stack 124 of retrieved sheets is housed in storage
location 80. The controller is operative to detect when the storage location is full
in a manner later discussed. The stack may be manually accessed and removed by rotating
frame 32 about shaft 44 to the position shown in Figure 8. This transversely disposes
the frame and the belt flights supported thereon away from the storage location. In
this position the stack 124 is more readily accessed for removal. Further, the printer
30 is also readily accessed for purposes of maintenance such as the changing of print
cartridges or the replenishment of paper supplies or servicing. Once the stack 124
of retrieved sheets has been removed from the storage location, the frame 132 is returned
to the operative position with the belt again extending between the sheet source which
is printer 30, and the outlet.
[0057] The retrieved sheets of the embodiment shown lie in a generally horizontal orientation
in the storage location 80. This is because the inside surface 88 of the gate member
76 extends generally about 180 degrees. However, in other embodiments of the invention
the gate member can have different inside surface contours and angular configurations.
For example, a 90 degrees arc may be used to align sheets vertically in a storage
location. This may be desirable if storage location space is available only below
the gate.
[0058] The system of the preferred embodiment is operated by controller 112 in a number
of different ways in response to the occurrence of certain programmed conditions.
For example, the controller operates to purge forms out of the receipt opening in
response to the storage location 80 being full, or in response to the receipt being
too long to retract. The controller also operates in ways which are operative to correct
malfunctions such as paper jams.
[0059] In the preferred embodiment of the present invention the controller 112 preferably
includes a microprocessor. The microprocessor is in operative connection with a memory.
The memory is preferably a semiconductor memory or firmware. However, in other embodiments
other types of memories may be used. The controller which operates the receipt transport
and retrieval system of the present invention may also operate the printer 30 and
control the printing of the receipt forms. In other embodiments of the invention separate
controllers for the printer and the receipt transport and retrieval system may be
used.
[0060] Schematic representations of the steps executed by the controller 112 are graphically
represented in Figures 13 through 24. Figure 13 is a schematic representation of the
steps executed by the controller in a printing and transport control routine. The
routine commences from a step 126 in which the printer is operating to print characters
or other indicia on the paper. At a step 128 the determination is made by the controller
112 as to whether the paper on which printing is being conducted was sensed as having
moved in response to the printer efforts to move the paper. Paper movement is preferably
sensed using the system shown in co-pending Application U.S. Serial No. 08/568,887
filed December 7, 1995 the disclosure of which is incorporated herein by reference.
If it is sensed that the paper is not moving in response to the printer, a fault indication
is given by the controller at a step 130.
[0061] If the controller senses that the paper is properly moving in response to the printer,
the controller next determines at a step 132 if it has received a form feed command.
If not, the controller next checks at a step 134 to determine if it has received a
cut command which is indicative of an instruction to the printer to cut the paper.
If no cut command has been received, a check is made at a step 136 to determine if
a present form command has been received. If no command to present a form has been
received, a determination is made at a step 138 if a command to retract the form has
been received. Finally, a check is made at a step 140 to determine if a purge command
has been received. If any of the commands represented in steps 132 through 140 have
been received, the controller is operative at a step 142 to enable the transport to
operate at medium speed. The transport is operated in accordance with the particular
steps associated with the command that it has received which are hereinafter discussed.
From step 142 the controller returns to step 126.
[0062] If none of the commands in step 132 through 140 have been received, a decision is
made at a step 144 as to whether the length of paper that the printer has operated
to print upon in the current form sufficiently protrudes from the printer to engage
the belt flights of the transport. This is preferably done by the controller comparing
a distance that the paper has been moved since the last cutting operation to a stored
value. If the paper is not yet sufficiently long to engage the belt flights the transport
is temporarily disabled at a step 146 and the program steps return to step 126. Once
the paper has reached a sufficient length to engage the belt flights the controller
executes a step 148. Step 148 is operative to begin moving the belts of the transport
in a forward direction at a slow speed. In the forward direction the belt flights
urge the sheet to move towards the receipt opening 24. As previously discussed, the
configuration of the transport is such that the belts are enabled to overrun in engagement
with the receipt form. From step 148 the belts continue to run at low speed until
one of the other commands is received.
[0063] Figures 14 through 17 schematically demonstrate the steps executed by the controller
as part of the paper loading and grading routine. The preferred form of the invention
is operative to sense characteristics of the paper so that the controller may dynamically
store and change stored threshold values to match the character of the paper in the
sheets being used. The preferred form of the invention is dynamically adaptable to
paper of varying quality and color. In the preferred form of the invention the controller
is also preferably operable to store and update threshold values that are indicative
of paper being sensed adjacent to a sensor as printing activities are conducted. In
this way the preferred form of the system is enabled to operate properly with paper
types that vary substantially. It also accommodates variations in the paper which
occur in the middle of a roll or fanfold stack. The system also dynamically adjusts
to the optical properties of "top of form" (TOF) marks when TOF type paper is used.
[0064] The paper loading and grading routine commences with an entry step 150 after which
a check is made at a step 152 as to whether the transport for the receipts is in the
operative position. If the transport has been moved to the position for servicing,
such as for changing the paper supply, the controller will next execute a step 154.
In step 154 the controller is operative to adjust a base paper color value to conform
with that presented at a sensor 155 (see Figure 7). Sensor 155 is preferably positioned
within a paper path indicated 151 within the printer 30. The sensor 155 is positioned
in the paper path at a location in advance of at least one paper drive mechanism schematically
indicated by rolls 157, 159 which engage the paper and move it in the paper path.
The sensor 155 is also preferably positioned in the paper path in advance of a paper
cutter mechanism, schematically indicated 153. Cutter 153 is selectively operative
to transversely cut the paper in the paper path. Sensor 155 is positioned sufficiently
inward in the paper path so that when the end of the paper is sensed at the location
by the sensor, the remaining paper can be moved outward by rolls 157 to engage the
belts of the transport at the nip 114.
[0065] In the preferred form of the invention the sensor 155 is an optical type sensor that
includes an emitter and a receiver. The controller is operative to adjust the intensity
of the emitter so that the level of light reflected from the paper and sensed by the
receiver in sensor 155 is increased to above a desired level. This assures that sensor
155 may reliably sense the paper adjacent thereto. In alternative embodiments however,
a stored threshold level of the signal from the receiver may be appropriately adjusted
to indicate the presence of paper, or both emitter and receiver threshold levels may
be adjusted in response to characteristics of the paper. This is preferably accomplished
based on reflectance from at least two spaced areas on a sheet, which are then used
to set the threshold. For example, the readings from the two spaced locations may
be averaged, and then an offset taken from the average for purposes of establishing
the threshold level. The signals from sensor 155 may also be used to change emitter
values or to adjust the paper sensing thresholds for signals from sensors 110 and
120.
[0066] At a step 156 a determination is made as to whether the paper which is being used
is top of form ("TOF") paper. This may be done by an input from a service technician
to the controller. However, in alternative embodiments it may be done automatically
by the sensor 155 detecting variations in reflectance from the paper which are indicative
of the presence of TOF marks. TOF marks are dark marks which are positioned on each
sheet form. They are used to provide a reference for the printing and cutting of the
form. Because TOF marks are uniformly positioned and are much darker (less reflective)
than the surrounding surface of the form, the controller may be programmed to respond
to the significant reflectance fluctuations associated with TOF marks and make the
decision in step 156 based on the presence or absence of such fluctuations.
[0067] If TOF paper is indicated to be present in step 156, the controller next executes
a step 158. In step 158 the printer is operative to advance the paper using rolls
157 and/or other drive mechanisms a sufficient distance to collect sample information
concerning both the reflectance of the paper in the area of the TOF marks as well
as in areas disposed from the marks. In the preferred form of the invention in step
158 the paper is advanced by the printer a distance of at least two TOF marks and
threshold values corresponding to the presence of paper and the presence of a TOF
mark on the paper adjacent to sensor 155 are updated and stored in memory. Thereafter
the controller executes a cut form routine at a step 160 which is later described
in detail, and proceeds to the steps that are later discussed in connection with Figure
16.
[0068] If it is determined at step 156 that the paper that is being used is not TOF paper,
the controller next executes a step 162. In step 162 the paper is advanced a sufficient
distance to insure that the printer is enabled to move the paper reliably. In the
preferred form of the invention the paper is moved forward about 25 centimeters. Thereafter
the controller proceeds to step 160 and cuts the paper using cutter mechanism 153.
[0069] If at step 152 it is determined that the transport is in the operative position the
computer next executes a step 164. Step 164 is a retract routine which is later discussed
in connection with Figures 22 and 23. In the retract routine the controller is operative
to move the belts of the transport to assure that any form therein is retracted and
moved into the storage location 80. This step assures that before new paper is loaded
the transport is clear.
[0070] The controller next executes a step 166. At step 166 the paper is moved forward in
the paper path 151 by the drive mechanism in the printer. At a timing step 168 it
is checked to see if an elapsed time has expired without the paper being sensed. If
the paper has been attempted to be moved forward beyond the elapsed time without being
sensed, the controller executes a step 170 in which the controller sets a status indicating
that the printer is out of paper or is experiencing a similar fault. From step 170
the controller exits the routine.
[0071] If the paper is sensed within the elapsed time permitted in step 168, the controller
moves on to a step 172. Step 172 is similar to step 154 previously discussed. In step
172 the controller is operative to evaluate the signals received from sensor 110 and
to adjust the threshold intensity of the emitter associated with the sensor, or the
threshold levels for signals from the sensor receiver to correspond with the reflectance
characteristics of the paper which has been loaded, The controller then moves on to
a step 174 which is similar to step 156 wherein a determination is made as to whether
or not the paper that has been loaded is top of form paper. As with the previously
discussed step this may be done based on an input or may be determined based on variations
in paper reflectance.
[0072] If top of form paper is being used the controller executes a step 176 in which it
sets threshold levels for detection of a TOF mark on the paper. These TOF mark threshold
levels are set based on the general reflectance of the paper which is determined at
step 172, if the decision as to the presence of TOF paper is based on a manual input.
If the determination is made automatically, the mark threshold levels may be based
on the reflectance characteristics of the TOF mark(s) sensed in the determination
process.
[0073] As shown in Figure 15, the controller next executes a step 178 in which a determination
is made whether the paper is adjacent to sensor 155. If paper is not sensed adjacent
to the entry sensor a determination is made at a step 180 as to whether the paper
is sensed adjacent to the exit sensor of the transport which is second sensor 120.
If paper is sensed adjacent to the exit sensor but not sensor 155 then there is a
problem and a faulty entry sensor status is set at a step 182.
[0074] After step 182 the controller is operative to execute a cut paper routine at a step
184 and execute a purge form routine at a step 186. These routines are later discussed
in detail. Thereafter the controller proceeds to execute the steps shown in Figure
16.
[0075] If at the decision step 178 paper is sensed adjacent to the sensor 155, the controller
proceeds to a step 188. Step 188 is again a determination as to whether or not top
of form paper is in use. This determination may be based on an input from a user,
based on a determination from variations in reflectance values from the paper, or
based on the decision that was made in step 174.
[0076] If it is determined that TOF paper is being used at step 188 the controller proceeds
to a step 190. In step 190 the printer is operative to move the paper so as to place
a TOF mark adjacent to sensor 155. The controller is thereafter operative to adjust
the threshold representative of the presence of a TOF mark. This may be done by either
adjusting the threshold intensity of an emitter associated with the sensor or adjusting
the threshold signal values corresponding to the adjacent TOF mark.
[0077] After adjusting the thresholds associated with the adjacent TOF mark in step 190,
the controller then executes the cut paper routine at a step 192. After cutting the
paper the controller executes the retract routine at a step 194 and advances the paper
to position the next TOF mark adjacent to sensor 155 at a step 156.
[0078] Alternatively, if in step 188 it is determined that top of form paper is not being
used, the controller advances to a step 198 in which a cut paper routine is executed.
At step 200 the form that has been cut is retracted back into the storage location.
At either step 196 or step 200 the controller is operative to execute a step 202 which
clears any residual status indication that the reading from the entry sensor is faulty.
[0079] From either step 186, step 202 or step 160 the controller proceeds to step 204 shown
in Figure 16. In step 204 the prior values which the controller had been using for
sensing TOF marks prior to execution of the current paper loading and grading routine
are deleted. Similarly, prior fault values such as a fault value indicative of a paper
out condition which existed prior to the current paper loading routine are cleared.
[0080] At a step 206 a determination is made as to whether in the course of the paper loading
and grading routine currently being executed, a "paper out" condition was sensed.
If not, the controller proceeds to a step 208. In step 208 the controller executes
a preprogrammed routine in which it prints a test pattern on a single form, advances
the form appropriately based on whether the form is a TOF form sheet or plain paper
sheet and executes a cut routine and a retract routine to place the form in the storage
location.
[0081] If the test routine at step 208 executes successfully, information indicative thereof
is indicated in the program parameters of the controller at a step 210. Of course,
if the apparatus has been determined to be out of paper at step 206, status information
indicative thereof is updated at step 210. After the status information is updated
the controller exits the program at a step 212.
[0082] During printing the printer responds to electrical signals from the controller which
are indicative of the indicia to be printed on the form that is to be delivered. As
indicated in Figure 13, once the amount of printing which has been done on the form
is sufficient to cause the form length to exceed a threshold, the controller executes
a step 144 which enables the transport to begin moving at a step 148. As printing
continues the form extends in the transport past the gate member, In the case of a
plain paper form the form may be a variable length which is determined by the amount
of printing thereon. In the case of a TOF form the form may be one or more connected
TOF sheets extending in the transport.
[0083] When the printing on the form is complete the controller is operative to execute
the steps in the cut form routine represented in Figures 18 through 20. Thereafter
the controller is operative to execute the steps in the present form routine shown
in Figure 21, which operates to present the form sheet to the customer.
[0084] The controller enters the cut form routine at a step 214. A determination is made
at a step 216 if entry into the routine is erroneous because the form length based
on the amount of printing is zero. If the form length is zero, the controller immediately
exits the routine at a step 218. Assuming that the form length is not zero as determined
at step 216, a determination is then made at a step 220 concerning whether the printed
form length is above the minimum necessary for transport. Again this decision is based
on the distance the printer has moved the form and conducted printing. If the decision
made in the step 220 is that the form length is below the minimum, a step 222 is executed
to advance the paper to the minimum form length.
[0085] From step 220 or step 222 the controller next executes a step 224 which involves
making a determination of whether the transport is clear. If in step 224 the exit
sensor 120 is sensing a form, a purge routine is executed at a step 226. The purge
routine will generally remove the form at the exit and clear the transport. If however
at a step 228 it is determined that the exit sensor is still not clear, a problem
status is indicated at a step 230 and the controller exits the routine at a step 232.
[0086] If at step 224 no form is detected near the exit sensor or if the purge routine executed
at step 226 is effective to clear the form, the controller executes a step 234. In
step 234 the printer cuts the paper by actuating cutter mechanism 153. In addition,
at step 234 the controller is also operative to update the top of form and paper reflectance
threshold values stored in memory based on the reflectance characteristics of the
particular form that has just been processed. This provides for updating the threshold
values for each sheet and compensates for variations which occur among the sheets.
[0087] In step 234 the controller next proceeds to a step 236 at which a determination is
made as to whether the transport is in the operative position. If so, the controller
executes step 238 in which the transport moves forward so as to move a form of the
minimum transportable length outward into the vicinity of the exit sensor 120. Alternatively,
if the transport is found not be in operative position at step 236, the steps shown
schematically in Figure 20 are executed as later discussed.
[0088] From step 238 the controller executes a step 240. In step 240 a determination is
made as to whether the paper is still being sensed adjacent to the entry sensor 110
in spite of the fact that the form should have been moved a distance sufficient to
place it adjacent to the exit sensor. If the form is still adjacent to the entry sensor,
a step 242 is executed in which the printer attempts to again cut the paper. From
step 242 the transport again attempts to move the form towards the exit sensor in
step 244. This time the advance of the form is attempted at middle speed.
[0089] The controller next executes a step 246. In step 246 a determination is again made
as to whether the form is still adjacent to the entry sensor 110. If so, the controller
executes a step 248 which indicates a failure status and exits the program at a step
250.
[0090] If however at step 240 or at step 246 the form is no longer sensed adjacent to the
entry sensor, the controller executes a step 252 which clears any cutter failure status
indication which may be in memory. The controller then operates the transport to advance
the form towards the exit at high speed in step 254. In step 256 a determination is
made as to whether the form is sensed adjacent the exit sensor 120. If so, the steps
shown in Figure 20 are executed.
[0091] If at step 256 the form is not sensed adjacent to the exit of the transport by sensor
120, a step 258 is executed. In step 258 the controller operates the transport so
as to advance the form at high speed towards the exit. A determination is then made
at a step 260 as to whether the form has reached the exit. If the form is now adjacent
to the exit sensor the controller proceeds to the steps in Figure 20. If however the
form is not adjacent to the exit sensor the controller proceeds to a step 262.
[0092] In step 262 a jam-clear routine, sometimes referred to as a jam recovery routine,
is executed. In the preferred form of the jam recovery routine the controller is operative
to move the belts 42 and 52 of the transport in a back and forth motion, first in
one direction and then the other. In the preferred form of the jam recovery routine
the belts move in a first direction and then in an opposed direction from the initial
starting point. This is done three times with the displacement of the belts in each
direction increasing with each cycle. The back and forth movement of the belts in
the jam recovery routine is generally operative to clear any jam and enable a stuck
sheet to begin moving. The jam recovery routine is used in a number of situations
by the preferred embodiment of the invention.
[0093] After executing the jam recovery routine the controller proceeds to a step 264 in
which a determination is made as to whether the form was seen during the jam recovery
routine adjacent to the exit sensor 120. If so, then the form has been freed and has
likely been moved either out of the transport or into the storage location. In response
to the form having been seen at the exit sensor, a step 266 is executed in which any
failure status indications are cleared and the controller proceeds to the steps in
Figure 20.
[0094] If however the jam recovery routine in step 262 was not sufficient to cause the form
to be sensed by the exit sensor, then the controller is operative at step 268 to indicate
a present failure status and the controller exits the program at a step 270.
[0095] From either step 236, step 256, step 260 or step 266 the controller proceeds as shown
in Figure 20 to a step 272. In step 272 any present failure status indications are
cleared. The controller then executes step 274 in which the form length and print
counters are reset. This enables the controller to begin calculating a form length
for the next form to be printed. At step 276 a check is made as to whether the transport
remains attached, and if so the controller moves to a step 278 in which it indicates
that a form for a customer is now in escrow in the transport. Of course, if the transport
is no longer attached then it is not appropriate to indicate that there is a form
in escrow. Thereafter the controller exits the routine at a step 280.
[0096] Having placed the form in escrow in the transport the controller is operative to
execute the present form routine schematically represented in Figure 21. It should
be understood that the presentation of printed forms is generally done one at a time.
However, the preferred embodiment of the present invention enables the holding of
more than one form in escrow in the transport if desired. This may be accomplished
through appropriate programming which verifies a form as cut by moving it adjacent
to the exit sensor 120 and then retracting it based on its length to an intermediate
point in the transport pending the printing of additional forms.
[0097] When forms that are in escrow in the transport are to be presented, the controller
executes the steps schematically indicated in Figure 21. The controller begins by
executing a step 282. From there a determination is made at a step 284 as to whether
the transport is properly attached. If the transport is not attached a determination
is made at a step 286 as to whether a form has been printed on or advanced. If not,
the controller sets a form taken status at a step 288 and exits the program at a step
290. Likewise, if a form has been printed upon the controller executes a step 292
to feed the form. From step 292 the controller then proceeds through steps 288 and
290 to exit the program.
[0098] If in step 284 it is determined that the transport is attached the controller proceeds
to a step 294. In step 294 a determination is made as to whether there is a status
indicated in memory which represents that there is a form in escrow in the transport.
If not, the controller exits the program. If however the proper status of a form being
in escrow is indicated, the controller executes a step 296. In step 296 the controller
operates the transport in an effort to move the form outward beyond the exit sensor
120.
[0099] While moving the form outward in step 296 an elapsed time is measured in a step 298.
If the form is not sensed as having moved outward past the exit sensor within the
elapsed time, then the jam recovery routine is executed at a step 300. The jam recovery
routine is similar to that previously discussed in which the belts move cyclically
back and forth in an effort to move the form.
[0100] After the jam recovery routine 300 a determination is made at a step 302 as to whether
the form is still being seen adjacent the exit sensor. If the jam recovery routine
was successful and the form is now not being seen by the exit sensor, or step 296
was successful in moving the form beyond the exit sensor, the transport is reversed
by the controller at step 304 to place the form adjacent to the exit sensor for monitoring.
The controller next executes a step 306 in which a status indication is given that
the form is being presented. Step 306 is also executed in response to the form still
being adjacent to the exit sensor at step 302.
[0101] After step 306 the controller is operative to execute a step 308. In step 308 the
controller monitors whether the form has been taken by the customer. If the customer
takes the form the form will be no longer detected by the exit sensor. Also during
step 308 the controller is operative to execute a timing routine. As previously discussed,
if the form is present at the exit sensor longer than a time set in the programming
of the controller, the form will be retracted in accordance with the steps described
in connection with Figures 22 and 23. When the form is presented in monitoring step
308 the controller exits the routine through a step 310.
[0102] If in step 308 the customer takes the form, then a form taken status is indicated
and the transport is ready to proceed to present the next form to either the same
customer or a different customer. If however the customer fails to take the form within
the time specified the controller is operative to execute the steps represented by
the retract routine graphically represented in Figures 22 and 23.
[0103] The controller enters the retract form routine beginning with a step 312. From step
312 a determination is made at a step 314 as to whether the transport is attached.
If not, the controller exits the program at a step 316. If the transport is attached,
the controller executes a step 318 in which a determination is made as to whether
a status is indicated as the transport having a form in escrow. If at step 318 it
is determined that the status indicative of a form being in escrow in the transport
is no longer in memory, the controller operates to execute a step 320 in which the
transport is run in reverse for sufficient time to retract any form that may be in
the transport into the storage location, and then exits the routine.
[0104] If at step 318 the controller determines that there is a status indication that a
form is in escrow in the transport, the controller moves to a step 322. In step 322
a determination is made concerning the length of the form that the printer has printed
based on the line counters in the printer. The determination made in step 322 is whether
the form is longer than the maximum length which can be retracted by the transport.
It should be understood that in the preferred embodiment of the invention the printer
is enabled to print forms which extend from the printer all the way through the transport
to the customer. Therefore it is possible to have a form which is longer than can
be retracted.
[0105] If at step 322 the form is determined to be longer than the maximum retractable length,
a step 324 is executed by the controller. In step 324 the steps in the purge routine
shown in Figure 24 are carried out. After executing the purge routine the controller
is operative to execute a step 326 in which the form status is indicated as taken,
and the controller exits the routine at a step 328.
[0106] If in step 322 it is determined based on the length of form printed that the form
in escrow is not too long to be retracted, the controller proceeds to a step 330.
In step 330 a determination is made as to whether the form is currently adjacent to
the exit sensor 120. If so, the controller executes a step 332 in which the transport
is run in reverse to clear the exit sensor. After executing step 332, a step 334 is
executed to determine if the form is still adjacent the exit. If so, the controller
executes a purge form routine at a step 336. Thereafter the controller is operative
to execute a jam recovery routine at a step 338. The controller then executes a step
340 to indicate that the form has been taken and exits the program at a step 342.
[0107] If at step 330 the form was found not to be adjacent to the exit sensor, the controller
executes a step 344. In executing step 344 the controller is operative to run the
transport in reverse until the form is sensed adjacent to the transport entry sensor
110. As shown in Figure 23, a determination is made at a step 346 as to whether the
form has moved adjacent to the entry sensor. If not, the controller is operative to
operate a jam recovery routine at a step 348.
[0108] If the form is determined to be adjacent to the entry sensor at step 346 or after
jam recovery routine 348, the controller is operative to execute a step 350. In step
350 the transport is continued to be run in a reverse direction until the entry sensor
is clear. This indicates that the form has been retracted and directed by the gate
member into the storage location 80. The controller next executes a step 352 in which
a determination is made as to whether despite the operation of step 350 the form is
still sensed adjacent to the entry sensor. If so, this is indicative that the storage
location is full. An indication thereof is given by the controller through the execution
of a step 354, and thereafter the controller exits the routine at a step 356.
[0109] If in step 352 the form is no longer sensed adjacent to the entry sensor this indicates
that it has been likely properly retracted into the storage location. The controller
next executes a step 358. In step 358 the controller is operative to run the transport
forward a short distance and then stop. A step 360 is then executed in which a determination
is made as to whether running the transport forward this short distance has pulled
a form from the storage location which is sensed by the entry sensor. If so, this
is indicative that the storage location is full and step 354 is executed.
[0110] If however in step 360 it is determined that the storage location is not full, a
step 362 is executed. In step 362 the controller is operative to run the transport
in reverse a distance similar to the distance that the transport was run forward in
step 358.
[0111] The controller next executes a step 364. In step 364 a determination is made as to
whether the form was seen by the entry sensor 110 during the course of conducting
the retract routine. If so, a step 366 is executed in which a form retracted status
is set by the controller. If however in step 364 it is determined that the form was
not sensed by the entry sensor, then this is indicative that the customer took the
form or that it was otherwise moved out of the transport. In response to this condition
the controller is operative to execute a step 368 and to set a form taken status.
From either steps 368 or 366 the controller exits the routine at a step 370.
[0112] The purge routine referred to in the discussion of the prior program steps is schematically
represented in Figure 24. The controller enters the routine through a step 372 and
thereafter makes a determination in a step 374 as to whether the transport is attached
to the printer. If the transport is not attached, the controller exits the routine
in a step 376.
[0113] The controller next executes a step 378 in which a determination is made as to whether
the printer has printed a form or a form has been advanced. If not, a form is advanced
at a step 380. The controller is then operative at a step 382 to run the belts of
the transport in a forward direction a distance sufficient to push any forms in the
transport outward through the receipt opening 24. In the preferred form of the invention
the distance that the belts are moved forward is about 50 centimeters.
[0114] After executing step 382 the controller next executes a step 384 in which a determination
is made as to whether either of sensors 110 or 120 detect a form adjacent thereto.
If so, a jam recovery routine is conducted at a step 386. The jam recovery routine
is similar to that previously discussed in which the belts undergo an oscillating
motion in an effort to clear a stuck form. After executing the jam recovery routine
a determination is made at a step 388 as to whether a form is sensed adjacent to either
of the sensors of the transport. If not, or alternatively if the transport sensors
were clear at step 384, the controller is operative at a step 390 to set a form purged
status indicative that the form has been pushed out of the receipt opening and that
the transport is clear. The controller is thereafter operative to exit the program
at a step 392. If however at step 388 it is determined that a form is still sensed
adjacent to one of the transport sensors, then the controller is operative at a step
394 to set a purge fail status. The controller then exits the routine.
[0115] A further novel feature of the preferred embodiment of the present invention is that
it avoids cutting of the paper when approaching the end of the paper supply. This
is particularly helpful when a continuous roll of paper is used as the supply and
the cutting of the paper after printing the "last" form will leave a short scrap of
paper which cannot be handled by the printer or transport. Such a scrap piece of paper
may jam the printer when new paper is fed.
[0116] A form length control routine which is executed by the controller is schematically
represented by the steps shown in Figure 17. The form length control is operative
in the processing of each form. This routine is critically involved when little paper
is left and it is desired to install a new roll or supply. Alteratively, the routine
may be used to test paper movement.
[0117] From an entry step 396 the controller proceeds to determine if the system is in a
transactional mode or a service mode at a step 397. The setting of this mode is based
on inputs or other conditions sensed by the controller. If the system is in service
mode, the controller proceeds to determine if a feed switch is enabled at a step 398.
The feed switch is a manual type switch that is enabled by the controller. For example,
the controller may disable the feed switch in response to certain status conditions.
If the feed switch is determined not to be enabled in step 398 the controller exits
the routine at a step 400.
[0118] From step 400 the controller next executes a step 402 to determine if the feed switch
has been manually pressed. This is done when test feeding paper or when unloading
paper from an almost depleted supply so a new supply may be installed. If the switch
has not been pressed the controller exits the routine at a step 404. If the feed switch
was pressed the controller moves on to a step 406.
[0119] In step 406, which is reached from either step 397 or step 402, a determination is
made as to whether the paper being used is TOF paper. As previously discussed, this
can be based on an input by a user indicative that TOF paper is being used. Alternatively,
this may be derived by moving the paper past the sensor 155 and sensing the periodic
variations in reflectance associated with the presence of TOF marks.
[0120] If TOF paper is indicated at step 406 the paper is advanced at a step 408 to the
next TOF mark or until the amount the paper advanced corresponds to a programmed maximum
form length. However, if TOF paper is not indicated in step 406, the non-TOF paper
is advanced in a step 410 an amount which corresponds to the minimum form length suitable
for handling by the transport.
[0121] At a step 412 a determination is made whether the feed switch is being manually held.
This is indicative that a servicer desires to unload the remaining paper. If the switch
is being held the printer and transport advance the paper to the maximum paper length
that can be retracted at a step 414.
[0122] From steps 408, 412 or 414 the controller proceeds to a step 416 wherein a determination
is made as to whether paper is still being supplied. This determination is preferably
made based on sensor 155 no longer sensing paper. Alternatively, the end of the paper
may be sensed using the apparatus disclosed in U.S. Patent Application Serial No.
08/568,887 the disclosure of which is incorporated herein by reference. If paper is
no longer being supplied, the cutting action of the cutter mechanism 153 associated
with the printer 30 is disabled at a step 417.
[0123] From step 416 or 417 the controller proceeds to execute the cut routine in step 418.
Of course if step 417 was executed the paper is not actually cut during the cut routine.
As a result all the paper remaining in the supply is moved through the printer and
into the transport. In other cases the length of form pulled into the transport in
step 418 will be the minimum form length or the maximum retractable form length.
[0124] From step 418 the controller determines if it is in transactional mode or service
mode at a step 419. If the machine is in service mode the controller executes a retract
routine at a step 420. The retract routine is operative to retract the form into the
storage location. If at step 419 the controller is in the transactional mode, the
controller executes a present form routine at a step 421. The execution of this routine
will generally result in delivery of the form to a customer. At a next step 422 the
controller operates to update its internal status record. If for example, the paper
is now out, a status indicative thereof is set. Likewise if a form was cut as a test,
the status set indicates that the paper is loaded and the transport is ready. The
controller then exits the routine at a step 426.
[0125] It should be understood that in the preferred form of the invention the paper cutting
and printing activities are suspended whenever the paper is sensed as depleted. When
paper is sensed as depleted, using sensor 155 in the printer or the system described
in the incorporated patent disclosure, the remaining paper is sufficiently long to
be moved by the printer transport mechanism through rolls 157, into engagement with
the belts of the transport. The transport carries the last portion of the paper away
from the printer. As a consequence, small pieces of paper which cannot be handled
by the printer or transport are not produced at the end of a paper supply. This avoids
problems associated with small pieces of paper that could jam the printer or cause
it to malfunction.
[0126] In the embodiment shown the sensor 155 is enabled to provide a signal to the controller
which indicates that it should cease further operation of the cutter. In this embodiment
this result is achieved because the location in the paper path at which sensor 155
senses the paper is disposed a first distance in the paper path from the final drive
rolls 157 which engage and move paper through the printer. This first distance is
greater than a second distance that the paper must extend beyond the drive rolls 157
in the paper path to reach the delivery area from which the form sheets may be taken.
In the preferred embodiment, the delivery area includes the nip 114 from which the
transport may take the sheets. Of course, in other embodiments the delivery area may
be an entrance to a different type of transport or an area in which a sheet may be
manually engaged by a customer.
[0127] In the preferred embodiment the cutter mechanism 153 is disposed in the paper path
upstream from the rolls 157, so the rolls may solidly move the cut sheets to the delivery
area. However, in alternative embodiments the cutter may be positioned on the downstream
side of the final drive rolls 157. Likewise, in the preferred embodiment the place
where indicia are printed on the paper by the printer mechanism is positioned upstream
in the paper path from both the cutter and the final drive rolls. However, different
arrangements may be used in other embodiments. Likewise while sensor 155 is used to
sense the presence of paper at a single location in the paper path, and the controller
discontinues cutting operations as soon as the sensor no longer senses the paper,
other embodiments may use other types of sensors and may delay the cessation of cutting
activities until the paper has moved a further distance beyond the condition where
the end of the paper supply is sensed. This will depend on the system configuration,
the ability to calculate the distance the paper moves and the amount of paper remaining
when the end of the paper is sensed. Those skilled in the art will devise other embodiments
of the invention which employ the fundamental aspects of avoiding production of a
form sheet which is too short to extend from the drive to the delivery area based
on the disclosure herein.
[0128] The virtual elimination of the possibility that small scraps of paper may remain
in the printer greatly reduces the amount of time that is required to replenish the
paper supply. With prior systems, if paper had been depleted it was necessary for
the servicer to check the printer for the presence of small paper scraps therein.
A failure to remove such scraps could cause a serious malfunction. To check for such
scraps the servicer usually needed to partially disassemble the printer to gain access
to its interior workings. This was very time consuming.
[0129] When the paper supply of the preferred embodiment of the invention is replenished
there is no need for a servicer to look for such scraps. In addition, the system includes
an auto load feature. When the paper supply has been depleted, the servicer extends
paper from a new roll or other supply into the printer. The paper is sensed by a paper
sensor within the printer positioned upstream of the drive rolls. In response to sensing
paper, the printer is operated to engage the paper and move it to a position in which
it is ready for printing. As a result the time required to install a new paper supply
is greatly reduced.
[0130] It will be appreciated by those skilled in the art that variations of the above-described
steps may be executed in efforts to clear jams and purge the transport. It will be
further understood that although the controller 112 is described as adjusting threshold
levels for detection of paper at the entry sensor 155, corresponding threshold levels
for detecting paper at the transport sensors 110 and 120 may similarly be adjusted.
This may be done either through the process of sensing successive areas on a sheet
with sensor 110 or 120 in a manner similar to that described with reference to sensor
155, or by adjusting threshold levels for one or both sensors 110 and 120 in accordance
with the paper characteristics as determined using sensor 155.
[0131] The preferred form of the present invention provides a simple yet highly reliable
transport and retrieval apparatus for receipts and other sheets delivered by an automated
banking machine. The invention is also highly compact because of the gate member and
the ability of the apparatus to store numerous retrieved sheets in a stacked relation
in a confined area. It also enables ready removal of the retrieved sheets as well
as superior access for servicing the components thereof. It is also self-adapting
to various form and paper types.
[0132] Thus the new sheet transport and retrieval system of the present invention achieves
the above-stated objectives, eliminates difficulties encountered in the use of prior
devices and systems, solves problems and attains the desirable results described herein.
