[0001] The present invention relates generally to handling and transport apparatus and more
particularly to mechanisms for handling and feeding sheet media. The present invention
is particularly applicable to a device for transporting sheet media such as currency,
tickets, coupons and the like, in an Automatic Teller Machine (ATM) and will be described
with particular reference thereto, although the present invention may find advantageous
application in other apparatus utilizing sheet feeding and handling mechanisms.
[0002] The present invention relates generally to a sheet media handling and dispensing
device for use in an Automatic Teller Machine (ATM), which device is capable of handling
individual sheet media, such as currency, coupons, tickets and the like, as well as
feeding a stack of such sheet media to a dispensing location.
[0003] Sheet media transfer devices known heretofore, particularly currency transfer devices,
have generally utilized roller systems or belt systems for driving and feeding the
sheet media (currency) within the device. Roller transfer systems are typically comprised
of cooperating pairs of opposed rollers wherein each opposed roller is rotated in
an opposite direction to drive the sheet media therebetween. Such pairs of opposed
rollers are generally disposed side-by-side, as well as in succession to form a path
along which the individual sheet media is to be fed. Belt systems operate in a similar
fashion by driving the sheet media between facing surfaces of opposed belts. Both
types of systems thus operate by frictionally gripping and driving the sheet media.
Such systems typically require precise alignment between successive pairs of rollers
or belts to ensure proper operation of the device. In addition, such systems require
precise timing between each roller or belt in the system. In this respect, if a particular
roller or belt is moving too slowly in relation to a successive roller or belt, the
sheet media may tear as the successive roller or belt accelerates the leading edge
of the sheet. If the roller or belt is moving too quickly in relation to the next
roller or belt, the deceleration of the leading edge may cause the sheet to buckle
and replicate itself which may jam the system. Accordingly, rollers and belts in systems
known heretofore are typically interconnected by timing chains or belts and are generally
driven by a single large motor which generally has a high power consumption.
[0004] Because of the intricacies of such systems, together with the highspeed at which
such devices normally operate, even slight misalignment or force imbalances can cause
excessive wear among the components, and more importantly can create document jammings
in the transport assemblies. Moreover, the intricacies and precise alignment found
in these systems also makes access to and removal of jammed sheets difficult.
[0005] The present invention overcomes these and other problems by providing a sheet media
dispensing device which is less complicated than currency feeding and handling system
known heretofore. The present invention provides a sheet media dispensing device which
utilizes a plurality of moving belts in operative relationship to a stationary surface
to transport sheet material along a path defined by the stationary surface.
[0006] In US-A-2028236, there is disclosed a drag belt conveyor for conveying sheets such
as telegram sheets, wherein a drag belt travels along a track for drag transport of
the sheets along the track.
[0007] In US-A-4618302, there is disclosed a device for accumulating paper sheets such as
bank notes, and for delivering the resulting stack of sheets while holding the sheets
firmly so as to prevent them from being disturbed.
[0008] In US-A-4577763, there is disclosed a system for dispensing bank notes, and more
particularly to a system which enables a single currency dispenser to be used by two
bank tellers.
[0009] According to the present invention, there is provided a device for dispensing sheet
media comprising:
storage means for storing sheet media to be dispensed;
a dispensing location accessible to a patron from which said sheet media may be dispensed;
receptacle means for retaining sheets of said media;

surface means and extend beyond the end thereof, said drive belts operable to drive
said sheet media along said planar surface means by frictional engagement between
said drive belts and said sheet media;
said planar surface means and said drive belts defining a generally planar straight
path along which said sheet material is to be driven;
said stacking means includes generally planar stacking surface means and is disposed
at one end of said planar surface means, said stacking surface means being movable
between a first position wherein said stacking surface means is displaced from said
elongated planar surface means to receive and stack sheets of said sheet media and
a second position wherein said stacking surface means is coplanar with said planar
surface means and disposed opposing a portion of the extending portion of said drive
belts to enable a stack of said sheet media to be moved along said path; and
said divert means is disposed adjacent said stacking means and includes generally
planar divert surface means which are coplanar with said planar surface means and
disposed opposing a portion of the extending portion of said drive belts, said divert
surface means being movable between a first position adjacent said stacking means
and a second position over said stacking means and adjacent the end of said elongated
planar surface mans when said stacking surface means is displaced from said elongated
planar surface means to enable sheet(s) of said sheet media to be driven over said
divert surface means by said drive belts past said stacking means to said receptacle
means.

[0021] Referring now to the drawings wherein the showing is for the purpose of illustrating
preferred embodiments of the invention only and not for the purpose of limiting same,
the drawings illustrate a card operated Automatic Teller Machine (ATM) 10 according
to the present invention for dispensing sheet media such as currency, traveller's
checks, tickets, coupons, and the like. Hereinafter, for purposes of clarity and convenience,
such sheet media, i.e. currency, traveller's checks, etc., shall be referred to as
"notes" or "a note", it being understood that the present invention find advantageous
application to the identified sheet media and others. Machine 10 is intended to dispense
notes upon request to individuals meeting predetermined criteria. Machine 10, which
is schematically represented in FIG. 1, includes a cabinet or housing 12 which encloses
an ATM processor 14, a media dispensing mechanism 16, hereinafter referred to as a
"media dispenser 16", and dispenser processor 18 for controlling the operation of
media dispenser 16.
[0022] ATM processor 14 basically controls the personal aspects of the dispensing routine
(i.e. the financial record keeping aspects and customer interface) of ATM 10. To facilitate
these functions, associated with AIM processor 14 are a video monitor 20 having a
screen 22 exposed to the exterior of housing 12, a keypad 24 including a plurality
of operational keys 26 for use by a customer for entering information to processor
14, and a card reader 28 for reading information from conventionally-known cards having
identification data encoded thereon. A card is inserted into card reader 28 through
a card slot 30 provided in housing 12. A currency dispensing opening 32 is provided
in housing 12 for dispensing currency to users of ATM 10.
[0023] Referring now to FIGS. 2-8, in the embodiment shown, media dispenser 16 is generally
comprised of the three separate modules, namely a bottom module hereinafter referred
to as a "feed module" and designated "34" in the drawings, an intermediate module
hereinafter referred to as a "stacking module" and designated "36" in the drawings,
and a top module referred to as a "transport module" and designated "38" in the drawings.
Find module 34, best seen in FIG. 5, is generally a storage location for the media
to be dispensed by the ATM 10 and is comprised of a housing 40 having side walls 42,
44. A pair of vertically-aligned panels 46, 48 form the front end of housing 40. Panels
46, 48 include outwardly facing, generally planar surfaces 46a, 48a which are aligned
and co-planar to each other. The back of housing 40 is open to receive conventionally-known
money canisters 50 on shelves 52. Canisters 50 in and of themselves form no part of
the present invention and therefore shall not be described in greater detail. Canisters
50 are basically rectangular boxes which hold a stack of sheet media, i.e. notes N.
The stack is biased by a push plate 54 and biasing means 56 toward an opening 58 at
one end of canister 50. A picker assembly 60 is provided adjacent opening 58 of each
canister 50 to remove ("pick") individual notes N from canisters 50. Picker assembly
60 is comprised of a cylindrical roller 62 which is rotatable about a shaft 64. Roller
62 includes a raised pad 62a which is operable to engage and remove ("pick") the exposed
note N in opening 58 of the canister 50, ...one note N being "picked" during each
single revolution of roller 62. In the embodiment shown, each roller 62 is preferably
driven by a separate, independently operated motor, designated 72a, 72b and schematically
illustrated in the drawings. Motors 72a, 72b are preferably stepping motors and include
sensing means (not shown) for monitoring each revolution of the roller 62, as well
as the position of raised pad 62a relative to opening 58. Below each roller 62 an
arcuate wall 74 is provided. A slot or opening 76 is defined between the end of arcuate
wall 74 and the lower end of each panel 46, 48. To identify the particular canister
50 inserted into few module 34 and particulars of the sheet media therein, a keyboard
66 having a plurality of switches 67 arranged in rows thereon is mounted in module
34 and connected to dispenser processor 18. Keyboard 66, illustrated in FIG. 16A,
is positioned to be aligned with corresponding rows of removable actuating pins 68
provided on the end of canister 50 above opening 58, illustrated in FIG. 16B. By inserting
actuating pins 68 at specific locations on canister 50, when inserting canister 50
into feed module 34 against keyboard 66 only corresponding switches 67 are actuated.
Using such an arrangement, the specific canister inserted in feed module 34 can be
identified, together with other parameters such as the particular type of note N contained
in canister 50, the height of the note and the note's thickness.
[0024] According to one aspect of the present invention, a vertical currency transport 80
for conveying individual notes picked from canisters 50 to stacking module 36 is provided.
Vertical transport 80 is basically comprised of a plurality of endless belts in operative
relationship with stationary surfaces. More specifically, in the embodiment shown,
three (3) identical, endless, side-by-side and parallel belts 82 are mounted on rollers
84. Rollers 84 are fixedly mounted to shafts 86, 88 and include annular grooves 84a
to receive ribs 82a on belts 82, as best seen in FIG. 6. Shafts 86, 88 are positioned
in housing 40 such that belts 82 define two parallel belt flights 90a and 90b wherein
flight 90b is adjacent to and a predetermined distance from surfaces 46a, 48a, of
panels 46, 48. In this respect, each belt 82 has an outer frictional surface which
faces surfaces 46a, 48a along flight 90b. As best illustrated in FIG. 6, surfaces
46a (not shown) and 48a each include a pair of side-by-side parallel rails 92 which
project therefrom. Rails 92 are juxtaposed relative to the belts 82 such that a rail
92 is disposed between each adjacent belt 82. In the embodiment shown, rails 92 are
integrally formed in panels 46a, 48a, but as will be seen below, rails 92 may be separate
components attached to planar surfaces. An undulated or corrugated passage 94 is formed
between the belts 82 and rails 92, as will be discussed in greater detail below. Belts
82 and rails 92 have a predetermined dimension and are spaced apart a predetermined
distance such that a note N is confined between belts 82 and rails 92 will be driven
along rails 92 in the direction belts 82 are moving. Accordingly, rails 92 and surfaces
46a, 48a are preferably smooth to enable notes N to move therealong. Shaft 86 is preferably
driven by a conventionally-known brush motor 96, which is schematically illustrated
in the drawings, having conventionally-known speed sensing means (not shown) associated
therewith.
[0025] Referring now to FIGS. 2-4 and 7-12, stacking module 36 is generally comprised of
a rectangular housing 100 formed by two side walls 104, 106, a bottom wall 108, and
a plurality of transverse walls 110, 112, 114, and 116 as best seen in FIG. 7. Transverse
walls 110, 112, 114, and 116 define three compartments or chambers 118, 120, 122 within
housing 100 wherein compartments 120, 122 are open on the top. The upper ends of side
walls 104, 106 include outwardly extending flanges 105, 107 respectively, best seen
in FIG. 11. Transverse walls 110, 112 define outward facing planar surfaces 110a,
112a respectively. In the embodiment shown, stacking module 36 includes a vertical
transport 130 along one end wall of the housing 100. Vertical transport 130 is basically
similar to the vertical transport 80 on feed module 34 and is dimensioned to be aligned
therewith. In this respect, vertical transport 130 includes three (3) generally identical
side-by-side and parallel belts 132 which are mounted on rollers 134 on shafts 136
and 138. As best seen in FIG. 7, shafts 136, 138 are spaced apart vertically and positioned
to define parallel belt flights 140a, 140b wherein belt flight 140b is disposed adjacent
and parallel to surface 110a of transverse wall 110. Belts 132 include outer frictional
surfaces which face planar surface 110a along flight 140b. Two generally L-shaped
rails 142 (best seen in FIG. 12A and 12B) are provided for mounting on stacking module
housing 100. Rails 142 include leg portions 142a, 142b which are mounted on transverse
wall sections 110, 112 respectively. Leg portion 142a is generally lower (flatter)
than leg portion 142b, and includes a laterally and longitudinal tapered ridge 142c.
Leg portion 142b, in addition to being higher, has a more rectangular cross-section.
Rails 142 are mounted to housing 100 so that leg portions 142a are parallel to and
juxtaposed with belts 132 such that a leg portion 142a of rail 142 is disposed between
each belt 132. In this respect, like vertical transport 80, an undulated or corrugated
passage is formed between the belts 132 and the rails 142. In the embodiment shown,
shaft 136 is driven simultaneously with shaft 86 of vertical transport 80 (by means
not shown) by motor 96. Associated with each belt 132 is a pinch roller 146 mounted
to transverse wall 110 as best seen in FIGS. 12A and 12B. Pinch rollers 146 are dimensioned
to be biased into engagement with belts 132.
[0026] Referring now to FIG. 7 and 9, transport module 38 is generally comprised of shallow
frame 150 having parallel side walls 152, 154. The upper edges of side walls 152,
154 include inwardly extending flanges 156, 158 (best seen in FIG. 9) which extends
along the length thereof. Frame 150 includes bottom walls 162, 164 at the distal ends
thereof and an open space defined therebetween. Bottom wall 162 includes an upward
facing, generally planar surface 162a. Frame 150 is mounted on housing 100 wherein
bottom wall 164 of frame 150 is above chamber 122 of housing 100. Bottom wall 162
of frame 150 extends beyond housing 100 with the opening between bottom walls 162,
164 being disposed over transverse wall 112, chamber 120, and a portion of chamber
122. Side walls 152, 154 each include a shallow notched-out area which defines a horizontal
slot 165 (best seen in FIG. 2) between the lower edges thereof and flanges 105, 107
of housing 100. The upper surface 162a of bottom wall 162 is generally aligned and
co-planar with surface 112a of transverse wall 112 of housing 100. Bottom wall 162
is dimensioned such that a gap or space 166 (best seen in FIG. 8) is defined between
the end thereof and transverse wall 112. A plate 168 having a dispensing slot 170
is mounted at the dispensing end of frame 150. Slot 170 is dimensioned to correspond
to slot 32 in housing 12. Plate 168 is mounted to an angle-shaped member 169 which
in turn is mounted to side walls 152, 154 of frame 150 wherein a space in defined
between plate 168 and the ends of side walls 152, 154.
[0027] Transport module 38 includes a horizontal transport 180 for moving the sheet media
along a generally horizontal path or plane. In this respect, horizontal transport
180 is similar to the vertical transport 80 of feed module 34 and transport 130 of
stacking module 36 in that it is basically comprised of a plurality of endless belts
in operative relationship with a stationary surface having elevated rails thereon.
More specifically, horizontal transport 180 includes three (3) generally identical
side-by-side parallel belts 182 which are mounted on rollers 184 on shaft 186, 188.
As best seen in FIG. 7, the shafts 186, 188 are spaced apart to define generally straight,
horizontal belt flights 190a, 190b. Belts 182 include outer frictional surfaces which
face surfaces 112a and 162a. Shafts 186, 188 are mounted in side walls 152, 154 such
that belt flights 190b of belts 182 are generally disposed parallel to and a predetermined
distance from surfaces 162a and 112a. More particularly, shaft 186 is mounted in inclined,
elongated slots 187 in side walls 152, 154. As seen in the drawings, belts 182 also
extend the entire length of transport module frame 150, and over chambers 120, 122
of stacking module 36. As best seen in FIG. 3, belts 182 are juxtaposed with respect
to leg portions 142b of L-shaped member 142, wherein a leg portion 142b is disposed
between each belt 182. Supplemental rails 192 are provided on wall 112 as best seen
in FIG. 3. Supplemental rails 192 are dimensioned to correspond to leg portions 142b
of L-shaped rails 142. Bottom wall 162 of frame 150 includes two (2) side-by-side
rails 194 which are aligned with leg portions 142b and dimensioned to correspond therewith.
Importantly, the upper surfaces of rails 142b, 192, and 194 are generally aligned
and lie in a common plane which defines path P. In other words, the upper surface
of rails 142b, 192, and 194 define the work path P along which the notes to be dispensed
are conveyed. As with vertical transports 80, 130, an undulated passage is defined
between belts 182 and rails 142b, 192, and 194. Belts 182 are preferably driven by
a conventionally-known brush motor 196, which is schematically illustrated in the
drawings, having conventionally-known speed sensing means (not shown) associated therewith.
In this respect, in the embodiment shown, horizontal transport 180 is driven independently
of vertical transports 80 and 130. If desired, however, horizontal transport 180 may
be simultaneously driven with vertical transports 80, 130 by a single motor, by means
within the purview of those skilled in the art, without detracting from the present
invention.
[0028] In addition to being in alignment with surfaces 112a, 162a, horizontal transport
180 is disposed to be in operative relationship with a stacking assembly 200 for stacking
the sheet media, a divert assembly 300 for diverting notes or dumping a stack of notes
to a "divert/dump location", a push plate assembly 400 for transferring a stack of
media toward dispensing slot 170, a gate assembly 500 for controlling access to slot
170, and a control assembly 600 for coordinating the actions of stacking assembly
200, divert assembly 300, and gate assembly 500.
Stacking Assembly 200
[0029] According to the preferred embodiment of the present invention, stacking mechanism
200 includes a stack plate 210 best seen in FIG. 7. Stack plate 210 is generally comprised
of a platform 214 having a planar upper surface 214a and a plurality of side-by-side,
parallel rails extending thereacross. In the embodiment shown, stack plate 210 includes
four (4) side-by-side, parallel rails 216. Rails 216 are basically dimensioned to
correspond in cross-section to rails 142b, 192, 194, and to extend in alignment therewith.
The ends of rails 216 are angled to correspond and to align with the angled ends of
rails 142b, 192, as best seen in FIG. 3. Stack plate 210 is generally disposed within
chamber 120 of stacking module 36. Slots are provided in walls 112, 114 to accommodate
the ends of rails 216 to the extent they extend beyond chamber 120. Elongated slots
218 extend through platform 214 and rails 216. Slots 218 are dimensioned to receive
vertical tines 220 on a media stop 222. Stop 222 is operable to be repositioned along
a guide 224. Stack plate 210 is mounted on a pair of elongated arms 226 which attach
to the sides of stack plate 210. Arms 226 extend toward the rear of the housing 100
along the exterior sides thereof and are mounted for pivotal movement on pivot pins
228 (shown in FIG. 2). In this respect, stack plate 210 is pivotally movable with
the arms 226 about the pins 228 between a stacking position (best seen in FIG. 7)
wherein stacking plate 210 is positioned away from belts 182 and second position wherein
rails 216 of stack plate 210 are aligned with rails 142b, 192, 194 and in operative
relationship with belts 182. In this position, the upper surfaces of rail 216 are
generally co-planar to plane P defined by the upper surfaces of rails 142, 192, and
194. The arm 226 adjacent wall 106 of stacking module 36 includes a laterally extending
cam follower 234 (best illustrated in FIGS. 13A-13D) in the form of a roller pin for
operative engagement with control assembly 600 which will be described in greater
detail below.
[0030] Stacking assembly 200 also includes a mechanism for aligning notes during stacking.
In the embodiment shown, the stacking assembly 200 includes three (3) paddle wheels
230 (best seen in FIG. 7) which are operative to align the individual notes against
wall 114 of housing 100. Each paddle wheel 230 is generally comprised of a central
hub 230a having a bore therethrough. Paddle wheels 230 are mounted on an shaft 232
which extends through chamber 118 of housing 100. A plurality of thin, narrow, radially-spaced
belts 230b extend outwardly from hub 230a to form a paddle wheel configuration as
best seen in FIG. 7. Wheels 230 are preferably formed from a neoprene material or
other similar material which is pliable and which has a "spongy" or adhering outer
surface to adhere or grip sheet material. As seen in FIG. 10, paddle wheels 230 are
spaced apart along shaft 232 such that paddle wheels 230 are disposed between belts
182 and rail 142b, 192 on wall 112. Slots are provided in walls 112, 114 to enable
the radial ends 230b of the paddle wheel to extend beyond walls 112, 114 during the
rotation of the paddle wheels 230. Paddle wheels 230 are driven by motor 196 via shaft
232. As indicated above, motor 196 also drives belts 182 of horizontal transport 180.
Divert Assembly 300
[0031] According to another aspect of the present invention, there is provided a divert
assembly 300 to divert individual notes or dump groups of notes from stacking assembly
200 to a designated "divert/dump location". The divert assembly 300 is primarily intended
to "divert" double bills (i.e. bills which are stuck together) and prevent such bills
from being issued to a customer. In addition, according to the present invention,
divert assembly 300 is also used in conjunction with the transfer assembly to "dump"
to the designated divert/dump location notes which have been presented to a customer,
but which have not been taken by the customer from presenter slot 170.
[0032] Divert assembly 300 (best seen in FIGS. 2, 3, and 7) is generally comprised of a
divert plate 310 which is slidably mounted for reciprocal movement on flanges 105,
107 of housing 100. Divert plate 310 is generally flat and includes an upper planar
surface 310a. Divert plate 310 is dimensioned such that surface 310a is generally
aligned and co-planar with surfaces 112a, 162a. Divert plate 310 includes four (4)
side-by-side parallel rails 312 extending across surface 310a. Rails 312 are dimensioned
to correspond to and be aligned with rails 216 on stack plate 210, rails 142b, 192
on surface 112, and rails 194 on surface 162a. In this respect, the upper surfaces
of rails 312 are co-planar to path P defined by rails 142b, 192, 194, and 216. As
shown in the drawings, the ends of rails 312 are angled along the longitudinal axis
thereof to conform to and mate with ends of rails 216 on the stack plate 210.
[0033] Divert plate 310 is dimensioned to extend through horizontal slots 165 and rest on
flanges 105, 107 of housing 100, as best seen in FIG. 11. One side of divert plate
310 includes a guide 314 (best seen in FIG. 11) which is dimensioned to receive the
lower edge of side wall 154 and is operable to maintain divert plate 310 in alignment
with frame 150. In this respect, the divert plate is movable between a first position
wherein the divert plate 310 is positioned over chamber 122 at one end of the stack
plate 210 (as best seen in FIG. 7) to a second position wherein divert plate 310 is
positioned above or over chamber 120 and stack plate 210. To permit divert plate 310
to move over tines 220 of media stop 222, stack plate 310 includes elongated grooves
316 formed below rails 242. A vertically oriented, generally rectangular plate 318
is attached to one side of divert plate 310. Plate 318 includes a vertically aligned
slot 320 (best seen in FIG. 2) which is dimensioned to operatively engage a control
pin on control mechanism 600 as will be discussed in greater detail below.
Push Plate Assembly 400
[0034] Push plate assembly 400 is generally comprised of a push plate 410 and means for
reciprocally moving push plate 410 the length of transport module 38. Push plate 410
is generally comprised of a rectangular platform 412 which extends between side walls
152, 154 of transport module 38. As best seen in FIG. 3, one end of 412 includes extensions
414 and the other end includes vertically spaced tabs 416. Extensions 414 define generally
L-shaped recesses 422 dimensioned to receive flange 156 and side wall 152, while vertically
spaced tabs 416 define a slot 424 to receive flange 158 of side wall 154, as best
seen in FIG. 11. Recess 422 and slot 424 are dimensioned to enable platform 412 to
slide freely on flanges 156, 158, with extensions 414 maintaining the lateral position
of platform 412. A plate 426 extends downward from platform 412. Plate 426 has a planar
surface 426a which is generally perpendicular to plane P (i.e. the upper surfaces
of rails 142b, 216, 192, 194, etc.). Plate 426 is dimensioned such that its lower
edge is immediately above (i.e. not touching), and can slide freely over surfaces
112a, 162a, 214a, and 310a. A plurality of notches 428 are formed in plate 426 to
accommodate belts 182 of horizontal transport 180 and the rails on stack plate 210,
divert plate 310 and modules 36, 38. A toothed belt 430 is secured to platform 412.
Belt 430 is driven by a motor 432 schematically represented in the drawings. Motor
432 is preferably a conventionally-known stepping motor having a speed sensor associated
therewith wherein the speed of motor 432 can be controlled and monitored. Motor 432
is mounted to the outer surface of wall 152 (not shown) of frame 150 and includes
a shaft 434 extending through wall 152 having a drive sprocket 436 thereon. An idle
sprocket 438 is mounted to Wall 152 adjacent dispensing slot 170. Sprockets 436, 438
are positioned such that toothed belt 430 is generally parallel to belts 182.
Gate Assembly 500
[0035] Gate assembly 500, best seen in FIGS. 2, 3, 7, 8, and 10, includes a box-like gate
510 having a bottom wall 510a, one end wall 510b which is dimensioned to be received
in the space between plate 168 and the ends of side wall 152, 154 of stacking module
38, and two parallel side walls 510c dimensioned to be disposed outside side walls
152, 154 of stacking module 38. Gate 510 is pivotally mounted to stacking module 38
by pivot pins 512 extending from side walls 152, 154. The gate side wall 510c adjacent
side wall 154 of transport module 38 includes a pin 514 which extends a rectangular
opening 516 (shown in phantom in FIG. 8) into a slot 518 at one end of an elongated
link 520. As shown in FIG. 8, link 520 is mounted to side wall 154 by pins 522 extending
through slots 524 in link 520, such that link 520 has limited longitudinal movement
along wall 154. Link 520 includes two downwardly extending fingers 525, 526. Finger
526 is biased by a spring 527 which urges link 520 and gate 510 toward the position
shown in FIG. 8 wherein end wall 510b is adjacent to and obstructs opening 170 in
plate 168.
[0036] Referring now to the other end of link 520, a laterally projecting arm 528 extends
from link 520 through a rectangular opening 530 in side wall 154. Arm 528 is operatively
attached to a generally L-shaped actuating member 532, best seen in FIG. 2. Actuating
member 532 is mounted to the outer side of side wall 154 by a pin 534 extending through
a slot 536 therein. An outwardly projecting pin 538 (shown in phantom in FIG. 2) is
provided at the end of actuating member 532 to operatively engage control mechanism
600 as will be discussed in greater detail below.
Control Assembly 600
[0037] To coordinate the movement and operation of stack plate 210, divert plate 310 and
gate 510, control assembly 600 is provided. The control assembly 600 is generally
comprised of a control wheel 610 which is mounted for rotation about a fixed axis
on an axle 612 (best seen in FIG. 11) which is secured to wall 106 of stack module
36. Control wheel 610 includes a cylindrical portion 614 and flange portion 616. As
best seen in FIGS. 13A-13D, cylindrical portion 614 includes an elongated curving
slot 618, which opens toward wall 106 of stacking module 36 and extends around axle
612. Slot 618 is comprised of three distinct portions, namely, a first, relatively
long concentric portion 618a which forms a major portion of slot 618, a shorter second
portion 618b which spirals inwardly from first portion 618a toward axle 612 and a
still shorter third portion 618c which is concentric about axle 612. Slot 618 has
a predetermined configuration which will be more fully understood from the subsequent
discussion of the operation of control wheel 610. Slot 618 is dimensioned to received
roller pin 234 on arm 226 of stack plate 210 and control pin 538 on actuator member
532 of gate assembly 500. Control Wheel 610 also includes an actuating pin 620 extending
inwardly from flange portion 616 toward wall 106. Actuating pin 620 is dimensioned
to be received within slot 320 of divert plate 310. Control wheel 610 also includes
an inwardly extending annular wall 622, best seen in FIG. 11. In this respect, wall
622 is generally concentric to the axis of axle 612 and projects toward side wall
106 of stacking module 36. Associated with control wheel 610 is a stepping motor 624
schematic designated in the drawings. Motor 624 is preferably positioned within the
housing 100 of stacking module 36 with a drive shaft 626 extending through wall 106.
Shaft 626 includes a tooth drive sprocket 628 for driving a tooth belt 630. Belt 630
is operable to drive a toothed ring 632 (best seen in FIG. 3) which is attached to
cylindrical portion 614 of control wheel 610.
Computer Processing Units 14, 18
[0038] Operations of ATM 10 and multi-media dispenser 16 are controlled by ATM processor
14 and dispenser processor 18 which are schematically illustrated in FIG. 17. In the
preferred embodiment of the present invention, ATM processor 14 is operatively associated
with card reader 28, monitor 20, screen 22, and keypad 24. Broadly stated, ATM processor
14 monitors and controls two generally separate aspects or functions of ATM 10, i.e.
the personal aspects of a transaction (the financial aspects and the customer interface)
and providing operational instructions to dispenser processor 18.
[0039] With respect to the former, ATM 10 is typically utilized in a media dispensing activity
involving a financial transaction, e.g. dispensing currency or purchasing tickets.
In this respect, ATM processor 14 is prowided to accept information data from a prospective
patron or customer, to ascertain from such data possibly in conjunction with a network
computer and (together with other data about such prospective customer from a record
source) whether the prospective patron or customer has a predetermined status necessary
to receive notes (typically withdraw currency) from ATM 10, to record data regarding
a withdrawal of notes or currency and to adjust the record data in response to a withdrawal
by a customer. In addition, ATM processor 14 is programmed to provide a patron with
information regarding features and functions of AIM 10 by means of the video screen
22 and the electronic display 20.
[0040] The information data from the patron is generally in the form of a conventionally-known
credit card having identification data encoded thereon. The credit card is inserted
into card slot 30 to be read by card reader 28 in a conventional manner. The card
provides information identifying the cardholder and provides other information with
respect to the prospective patrons financial status, which may be in the form of data
with respect to financial record files or financial institutions. Such data, utilized
together with data from a record file or an external source, determines whether the
prospective patron is authorized to utilize ATM 10. In this respect, processor 14
may have an internal record file including the account numbers of all patrons for
whom the access machine is allowed, or it may be connectable by a modem 250 (or directly
by a dedicated line) to an external record source such as a financial institution
or credit authorization service in a manner conventionally-known in automatic bank
teller machines. With information from the credit card, together with information
from the internal or external record source, ATM processor 14 can determine whether
the identified patron has the appropriate status to make a media or currency withdrawal.
If authorized, data regarding parameters of the dispensing (i.e. date, time, amount,
etc.) are recorded in file storage of ATM processor 14. The financial records of the
patron are modified (debited) based on the value of the notes or currency dispensed.
With to this modification of the financial records, if the records are maintained
internally by the machine, such modification can be done by ATM processor 14. If the
financial records are external of the machine (at a financial institution or credit
authorization service), information regarding withdrawal transaction are transferred
to such external records from ATM processor 14. As set forth above, communications
with the external records may be accomplished by modem 250, as shown by FIG. 17 or
directly by a dedicated line (not shown). With the modem arrangement, information
concerning several transactions may be stored in file storage of processor 14 throughout
the day and then transferred to the external records at one time, thereby saving on
transmission and hook-up costs. ATM processor 14 may also include printer means (not
physically shown) providing patrons with a records of all transactions.
[0041] Thus, with to the financial and customer interface aspects of the present invention,
ATM processor 14 basically provides a means for identifying patrons, means for communicating
with the patrons, means for checking a patron's financial status, means for monitoring
the withdrawal transaction, and means for means for modifying a patron's financial
records.
[0042] Referring now to the operational function of ATM processor 14, processor 14, based
on information from a customer, basically instructs dispenser processor 18 as to the
number of notes to be dispensed and the number of notes to be dispensed from each
canister (in the event canister 50 holds different types of notes).
[0043] Referring now to dispenser precursor 18, as schematically illustrated in FIG. 17,
processor 18 basically controls and monitors the operation of picker mechanisms 60,
vertical transports 80 and 130, horizontal transport 180, stacking assembly 200, divert
assembly 300, push plate assembly 400, gate assembly 500, and control assembly 600.
These components are controlled via picker motors 72a, 72b, vertical transports drive
motor 96, horizontal transport drive motor 196, push plate drive motor 432, and control
wheel drive motor 624. As indicated above, motors 72a, 72b, 96, 196, 432, and 624
include sensing means (not shown) wherein dispenser processor 18 can monitor the relative
position of components associated therewith. In addition to these sensing means, media
dispenser 16 includes several other sensors. Referring now to FIG. 5, sensors 710
are disposed below each picker mechanism 60. Sensors 710 are of a type disclosed in
United States Patent No. 4,664,369 (which is owned by the assignee of the present
application) and are operative to sense the thickness of notes being transferred thereover.
The teachings of U.S. Patent No. 4,664,369 are hereby incorporated by reference into
present application. Sensors 710 monitor notes picked by mechanisms 60 and to ensure
doubles, (i.e. notes which may be stuck together) are not dispensed to a customer.
A counting sensor 720 is provided in the upper surface of leg portion 142b of L-shaped
rail 142 (best seen in FIG. 3) to count notes which pass thereover as they move to
stacking assembly 200. A exit sensor 730 is provided in the upper surface of rail
194 to sense the position of a stack of notes being presented to a customer through
slot 170. A gate sensor 740 (best seen in FIG. 8) is provided on side wall 154 in
operative relation to finger 525 to monitor the positions of gate 510. A control wheel
sensor 750 (shown in phantom in FIGS. 13A-13D) is provided to monitor the positions
of control wheel 610. Sensor 750 is generally U-shaped and is disposed such that wall
622 is disposed between the legs thereof. Sensor 750 is operable to sense notches
and windows (not shown) formed at predetermined positions in wall 622. The notches
and windows correspond specific important operational positions of control wheel 610.
The important operational position of control wheel 610 are illustrated in FIGS. 13A-13B
and will be discussed in greater detail below.
[0044] In addition to sensors 710, 720, 730, 740, and 750, dispenser processor receives
information from keyboard 66. Keyboard 66 provides information which identifies the
particular canister 50 inserted into multi-media dispenser 16, but more importantly,
it also identifies the type of media (notes currency, etc.) within canister 50, the
height of the notes, and the thickness of the note contained therein. Information
from keyboard 66 is communicated by dispenser processor 18 to ATM processor 14.
Transports 80, 130, 180
[0045] Referring more specifically to vertical transport 80, 130, and horizontal transport
180, each is basically comprised of a plurality of side-by-side, parallel belts juxtaposed
with a plurality of side-by-side parallel rails. The belts and rails are aligned and
extend in the same direction. As best illustrated in FIG. 6, the rails are interjacent
the belts and spaced a predetermined distance therefrom. The rails basically define
elevated surfaces which generally lie in a common plane and define the path along
which the notes are conveyed. In each transport, the operative frictional surface
of the belts are disposed below the plane defined by the elevated rail surface in
the space defined therebetween. In this respect, the belts and rails mesh and interact
to provide an undulated or corrugated passage therebetween. Specifically, notes disposed
between the belts and the rails preferably engage the belts sufficiently to maintain
fictional engagement therewith and to be motionless relative thereto as the belts
move between the rails. In this respect, the elevated surfaces are preferably smooth
to allow the notes to freely slide thereover.
[0046] As best seen in FIGS. 4-6, the rails of vertical transports 80, 130 are tapered along
their longitudinal and lateral edges. The rails of horizontal transport 180 (including
the rail on stack plate 210 and divert plate 310) while having tapered and angled
longitudinal edges are generally rectangular in cross-section (best seen in FIGS.
10 and 11). Moreover, the rails of horizontal transport 180 are slightly higher (elevated)
than those on vertical transports 80, 130. These differences are basically due to
the function of each transport.
[0047] In this respect, vertical transports 80, 130 are provided to transport single notes
in a vertical direction, as best illustrated in FIG. 4. For such an operation, it
is basically only necessary that successive rails be aligned and that the upper surface
of the rails lie in a common plane. As seen in FIG. 4, the configuration of the successive
rails, as well as the belts, may vary so long as the rails and belts are aligned and
are operable to convey a note. Horizontal transport 180 on the other hand is provided
to convey a stack of notes (as well as single notes) in conjunction with push plate
410. In this respect, to ensure close cooperation between push plate 410 and the respective
rails, the lateral edges of the rail are to match the squared corners of the notches
provided in push plate 410. Moreover, the rails of horizontal transport 180 are higher
to enable push plate 410 to extend below the upper surface of the rails a distance
sufficient to ensure that no notes will pass or be wedged under the bottom edge of
push plate 410 during operation.
[0048] Accordingly, the height and cross-sectional configuration of the rails in and of
themselves are not critical to the present invention. It is only important that the
rails and belts be aligned and juxtaposed in operative relation to another to form
an undulated passage therebetween (i.e. the frictional surface of the belts is below
the elevated surface of the rails) and are operable to maintain frictional engagement
between the belts and the notes to be conveyed. It will also be appreciated that the
lateral spacing between adjacent rails and belt may vary depending on the sheet media
to be conveyed, and that the number of belts and rails may vary. In each of the transports
shown, three belts and two rails are provided. In this respect, it is believed at
least two rails are necessary to maintain alignment of the notes. In the embodiment
shown, additional rails are shown on stack plate 210 and divert 310. It has been found
that additional rails on these members facilitates better stacking by supporting the
lateral ends of the notes and that such support assists in ensuring proper engagement
between a stack of notes and push plate 410. In the embodiment shown, belts 82, 132
of vertical transports 80, 130 are of an un-reinforced urethane, belts 182 of horizontal
transport 180 are formed of nylon reinforced, semi-stretch neoprene.
Operation
[0049] Referring now to the operation of ATM 10, media canisters 50 are inserted into multi-media
dispenser 16 as shown in FIG. 5. Pins 68 on canister 50 are positioned to engage specific
switches 67 on keyboard 66. In the embodiment shown, actuation of the preselected
switches 67 identifies to dispenser processor 18: (1) the specific canister 50 (identification
code) being inserted into the machine; (2) the media (notes) contained within the
canister 50; (3) the thickness of the notes; and, (4) the height of the notes. This
information is communicated to ATM processor 14 by dispenser processor 18. In the
embodiment shown, two canisters 50 may be utilized. Importantly, according to the
present invention each canister 50 may contain a different type of note. For example,
canisters 50 may contain the same type of currency but each canister 50 having a different
denomination. In another respect, one canister 50 may contain currency of a particular
size and thickness and the other may contain coupons having a completely different
size and thickness. In other words, media dispenser 16 is operational with two dissimilar
types of notes.
[0050] The following discussion of the use and operation of ATM 10 is based upon a dispensing
transaction involving financial value wherein a patron or customer must meet a predetermined
status. It will, of course, be appreciated that ATM 10 and media dispenser 18 may
be programmed to operate merely upon request by any individual.
[0051] Use of a ATM 10 is initiated by a customer inserting a conventionally-known credit
card into card slot 30. The card, which is read by cardreader 28, provides information
identifying the cardholder and provides other information with respect to the prospective
patron's financial status. If the media contained within the ATM 10 has value, typically
an approval of the customer's financial status is required. ATM processor 14 may have
an internal record file including the account numbers of all patrons for whom access
to the machine is allowed, or ATM processor 14 may connect via modem 250 or dedicated
line (not shown) to an external record source such as a financial institution or credit
authorization service to check the status of the customer. In a conventionally-known
manner, ATM processor 14 can advise the customer via screen 22 of monitor 20 whether
access to the machine is allowed and provide instructions as to procedures for the
customer to follow to receive notes from ATM 10. The transaction is conducted by the
customer entering pertinent information (in response to prompts by ATM processor 14)
using operation keys 26 on keypad 24. When the pertinent information has been entered
and processed, processor 14 will instruct dispenser processor 18 as to the number
of notes to be dispensed from canister 50.
[0052] Having received instructions form ATM processor 14 with respect to the number of
notes to be dispensed, dispenser processor 18 initiates dispensing of the notes in
a predetermined sequence.
[0053] FIG. 14A shows general positions of the respective components of media dispenser
16 when dispensing of notes is initiated. As indicated above, control wheel 610 coordinates
the operation of stack plate 210, divert plate 310 and gate 510. In this respect,
FIG. 13A shows generally the position of control wheel 610 to locate the operative
components, i.e. stacking plate 210, divert plate 310, push plate 410, and gate 510,
to the positions shown in FIG. 14A. FIG. 13A shows control wheel 610 in a first position,
wherein pin 234 which is associated with stacking plate 210 and pin 538 which is associated
with gate 510 are disposed within slot portion 618a of cam slot 618. Actuating pin
620 is disposed at the bottom of slot 320 of divert plate 310. With control wheel
610 in this position, stack plate 210 is in a first position disposed below and away
from belts 182 of horizontal transport 180, divert plate 310 is a position shown in
FIG. 14A, and gate 510 is in a normal, closed position. Push plate 410 which is independently
controlled by dispenser processor 18 via motor 432 is positioned in a rearmost location
as shown in FIG. 14B. Media stop 222 is preferably fixedly positioned within media
dispenser 16 to a position which will accommodate the largest media expected to be
used in media dispenser 16. According to the preferred operation of the present invention,
divert plate 310 and push plate 410 are repositioned by dispenser processor 18 prior
to dispensing to predetermined positions relative to stack plate 210 as shown in phantom
in FIG. 14A. These positions are determined by dispenser processor 18 based upon the
height of the note to be dispensed, which information was provided by keyboard 66.
Push plate 410 is repositioned by dispenser processor 18 by means of motor 432. Divert
plate 310 is repositioned by dispenser processor 18 by rotating control wheel 610
by motor 624. Control wheel 610 as viewed in FIG. 13A would be rotated clockwise a
predetermined angle from the position shown. The amount of rotation being calculated
and monitored by dispenser processor 18 via information from stepping motor 624 and
the positional sensor therewith (not shown) and sensor 750. The rotation of control
wheel 610 causes actuating pin 620 to move along an arcuate path to the right as seen
in FIG. 13A, wherein actuating pin 620 moving through vertical slot 320 causes divert
plate 310 to move to the right in FIG. 13A (to the left in FIG. 14A).
[0054] Dispenser processor 18 initiates vertical transport motor 96 and horizontal transport
motor 196 such that belts 82 of vertical transport 80, belts 132 of vertical transport
130 and belts 182 of horizontal transport 180 move in the direction shown in FIG.
14A. Dispenser processor 18 then initiates picker mechanisms 60 in sequence to pick
individual notes from canisters 50. If media dispenser 16 contains notes of different
sizes, dispenser processor 18 is programmed such that the largest note is dispensed
first. In this respect, an individual note is picked by pad 62a of roller 62 which
feeds the note toward flight 90b of belts 82 of vertical transport 80. The individual
note passes over thickness sensor 710 which scans the thickness to ensure that a single
note is being transferred. Sensor 710 has been programmed by processor 18 to monitor
a predetermined thickness. In this respect, the programmed thickness is determined
by the information provided to processor 18 and ATM processor 14 by switches 67 on
keyboard 66. The individual note engages flight 90b of belts 82 which bend the note
upward, the note being trapped in undulated passage 94 between the belts 82 and rails
92. In this respect, the outer frictional surface of the belts 82 force the note along
rails 92. The note is driven to vertical transport 130 wherein belts 132 force the
note along L-shaped rails 142 toward horizontal transport 180. As best seen in FIGS.
12A, 12B, belt 132 forces the note between pinch roller 146 and roller 134. Pinch
roller 146 produces a "hard drive" to force the note under a positive friction. This
"hard drive" forces the leading edge of the note into flight 190b of belts 182 of
horizontal transport 180, as best seen in FIG. 12B.
[0055] The leading edge of the note generally causes flight 190b of belts 182 to deflect
upward as belts 182 pull the leading edge of the note in the direction of the moving
belt. The amount of deflection depends on the thickness and rigidity of the note being
transferred. Importantly, this resilient feature enables dispenser 18 to transfer
rigid cards as well as pliable currency. Notes transferred to horizontal transport
180 are confined between belts 182 and the upper surfaces of leg portions 142b of
L-shaped rails 142 and supplemental rails 192. The frictional outer surface of belts
182 drives the note along rails 142, 192. Note N is driven horizontally by horizontal
transport 180 until it is positioned above stacking plate 210. As the horizontal movement
of the note brings it to a position above stack plate 210, belts 230b of paddle wheels
230 catch the upper surface of the note and force it downward onto stack plate 210.
Movement of the flexible belts 230b across the upper surface of the note, also draw
the note against traverse wall 114 to align the leading edges thereof. Importantly,
as indicated above, divert plate 310 and push plate 410 are positioned prior to the
stacking sequence to generally align with tines 220 of media stop 222 as schematically
represented in FIG. 14A. In this respect, media stop 222, divert plate 310, and push
plate 410 provide a positive barrier to prevent the notes from being transferred beyond
the stacking position. Counting sensor 720 on leg portion 142b of L-shaped rail 142
counts the individual notes as they pass thereover to insure that the correct number
of notes have been picked by picker assembly 60 and transferred to stack plate 210.
[0056] If a second type or denomination of note, possibly a smaller note, is to be dispensed,
such notes are transferred in a similar manner from their respective canister 50.
Importantly, during the stacking of the smaller notes, divert plate 310 and push plate
410 are repositioned by dispenser processor 18, i.e. moved horizontally to the left,
a predetermined amount to provide a barrier for the smaller note. Again, the position
of divert plate 310 and push plate 410 is calculated by dispenser processor 18 based
upon the information received with respect to the height of the smaller note. The
smaller media is then stacked upon the larger media in a manner previously described
wherein the edges of bath notes (i.e. the larger and smaller) are aligned by paddle
wheels 230 against transverse wall 114.
[0057] During the picking of the notes from canisters 50, some notes may have a tendency
to stick together wherein double bills may be detected by sensor 710. In such an event,
dispenser processor 18 reverses direction of the picker roller 62 in an attempt to
separate the double bills. If the double bill cannot be separated by repeated reversing
of picker roller 62, media dispenser 16 is operable to divert the double to a "divert/dump
location" located in compartment 122 of stacking module 36. To accomplish "dumping"
or "diverting" of notes, divert plate 310 is moved to the left to a position above
stack plate 210 as schematically illustrated in FIG. 14B. Movement of divert plate
310 is initiated by control wheel 610 as shown in FIG. 13B. In this respect, to move
divert plate 310 to the position schematically illustrated in FIG. 14B, control wheel
610 is rotated by motor 624 in a clockwise direction as viewed in FIG. 13B. In this
respect, actuating pin 620 moves divert rectangular plate 310 to the right (as seen
in FIG. 13B) by moving through slot 320 of plate 318 in a manner as discussed above.
The positions of stack plate 210 and gate 510 remain the same as pins 234 and 538
move through slot portion 618c which is generally concentric about axle 612. The double
bills are conveyed by vertical transports 80, 130 to horizontal transport 180. Belts
182 drive the "doubles" over rails 312 of divert plate 310 into chamber 122 of stacking
module 36. The diverted notes are monitored by dispenser processor 18 and ATM processor
14. A divert/dump canister having a similar keyboard type of arrangement may be provided
in chamber 122 wherein the specific canister and the amount of currency dumped therein
can be monitored. After the double bill has been diverted, control wheel 610 causes
divert plate 310 to return to a stacking position generally shown in FIG. 14A, wherein
further stacking of notes, monitored by dispenser processor 18, can be conducted until
the appropriate number and type of notes are stacked.
[0058] Upon completion of the stacking of the notes to be dispensed, push plate 410 is moved
back to clear stack plate 210 and stack plate 210 is moved from its first stacking
position to a second elevated position, as schematically illustrated in FIG. 14C,
wherein rails 216 are aligned with rails 142, 192, 194 and in operative engagement
with belts 182 of horizontal transport 180. Such movement is initiated by dispenser
processor 18 which causes control wheel 610 to rotate in a counterclockwise direction
to a position as illustrated in FIG. 13C. As shown in FIG. 13C, divert plate 310 has
been moved to its rear most position by actuating pin 620 which upon further rotation
of control wheel 610 in a counterclockwise position rotates away from slot 320. The
counterclockwise rotation of control wheel 610 causes pin 234 on arm 226 to move from
its initial position in cam slot portion 618a through cam portion 618b, which urges
pin 234 toward axle 612 causing arm 226 to pivot about pin 234 and to bring stack
plate 210 into alignment with the operative plane P.
[0059] With stack plate 210 in the position shown in FIG. 14C, push plate 410 is initiated
by dispenser processor 18 to drive the stack of notes toward gate assembly 500. Simultaneously,
belts 182 of horizontal transport are driven such that flight 190b moves toward gate
assembly 500. According to a preferred method of operation of the present invention,
if the stack of notes to be presented are all the same, push plate 410 is driven at
a rate faster than belts 182 of horizontal transport 180. If the stack contains notes
of two separate sizes, both sizes being aligned along their leading edges, dispenser
processor 18 preferably causes belts 182 of horizontal transport 180 and push plate
410 to be driven simultaneously at the same speed such that relative movements of
the smaller notes relative to the larger notes does not occur.
[0060] As the stack of notes is moved toward gate assembly 500, the leading edge of the
stack encounters exit sensor 730 on rail 194. Upon exit sensor 730 sensing the leading
edge of the stack, dispenser processor 18 causes control wheel 610 to rotate further
in a counterclockwise direction to the position shown in FIG. 13D. Such rotation causes
pin 538 to move through cam slot portion 618b which forces pin 538 toward axle 612.
This movement forces actuating member 532 to the left as shown in FIG. 13D. Referring
now to FIG. 8, the aforementioned movement of actuating member 532 causes link 520,
as shown in FIG. 8, to move to the left. Slot 518 on link 520 causes pin 514 on gate
member 510 to move downward to the position shown in phantom FIG. 8 wherein gate 510
is moved down, away from slot 170. Dispenser processor 18 then causes push plate 410
to move the stack of notes a predetermined distance through slot 170 to be accessible
to the customer. The "predetermined distance" is based upon the size parameters of
the note as indicated by switches 67 on keyboard 66. Slots 187 in side walls 152,
154 enable shaft 186 and belts 182 to move upward to accommodate large stacks of notes.
The customer may then take the notes presented through slot 170 which is generally
aligned with dispensing opening 32 in housing 12. When the notes are removed by the
customer, exit sensor 730 indicates the absence of the notes. Processor 18 then causes
control wheel 610 to return to the position shown in FIG. 13C wherein spring 527 acting
on finger 526 (best seen in FIG. 8) forces link 520 to return gate 510 to a closed
position. Gate sensor 740 which generally monitors the position of finger 525 on link
520 indicates when gate 510 has assumed a closed position. Push plate 410 then returns
to its normal home position.
[0061] In the event, that the stack of notes presented is not taken by the customer, dispenser
processor 18 causes push plate 410 to move back a predetermined distance and belts
182 of horizontal transport 180 to reverse direction to move the stack of notes away
from gate 510. Exit sensor 730 indicates when all the notes have been moved away from
slot 170. control wheel 610 is then actuated, as discussed above, to close gate 510.
Processor 18 then rotates control wheel 610 to the position shown in FIG. 13B wherein
divert plate 310 is positioned over stacking plate 210. Push plate 410 is moved back
to a home position, and belts 182 of horizontal transport 180 are actuated to transfer
the untaken notes to the "divert/dump location" in chamber 122 of stacking module
36. Information regarding the untaken notes is communicated to ATM processor 14 via
dispenser processor 18. Upon completion of the transaction, ATM processor 14 may provide
a customer with a printed summary of the transaction via a printer (not shown).
[0062] As can be appreciated from the foregoing description, the present invention provides
a media handling and feeding device which is relatively simple in design and operation,
yet which provides several considerable advantages over media dispensing devices known
heretofore. In this respect, as indicated above, prior transfer assemblies generally
included moving elements which are in operative engagement with other moving elements,
i.e. roller-to-roller or belt to belt. Such interaction inevitably produces wear among
such elements, which wear can effect the overall operation of the device. Unlike these
prior devices, a transport according to the present invention has no surface-to-surface
interaction in that, as indicated above, notes are transported through a space defined
between moving belts and stationary rails. Thus, no surfaces interact or rub against
each or which can cause wear or create static electricity. Moreover, such a transport
system requires substantially less power than prior belt or roller systems.
[0063] More importantly, however, it is the manner in which the notes are transferred. Because
of the space between the belts and the rail surfaces, only slight frictional forces
are exerted on each note. In other words, a transport according to the present invention
produces a relatively low driving force on the notes. While such force is sufficient
to convey notes along the rail surfaces, it is insufficient to pull the notes from
components exerting a greater frictional force thereon or to retard the motion of
the note when engaging a component exerting a greater force thereon. For example,
in the embodiment shown, picker assemblies 60 are provided to pick individual notes
from canisters 50. As indicated, occasionally bills will stick together to produce
doubles, in which case the direction of rotation of picker roller 62 is repeatedly
reversed in an attempt to separate the double bills. During such an operation, a portion
of the "double" may be disposed within vertical transport 30 between belts 82 and
rails 92. According to the present invention, the relatively low frictional driving
force exerted by belts 82 on the notes are insufficient to pull it from picker assembly
60. In this respect, only When a note or "double" is released by mechanism 60 will
belts 82 be able to convey such note or double along rails 92. Important, in this
respect, is that the speed of belt 82 need not be timed to cooperate with roller 62
of picker assembly 60, and is therefore not limited by the speed of picker assembly
60. Consequently, belt 82 may move at a much greater speed than picker roller 62.
In similar respects, belt 182 of horizontal transport may move at a different speed
than belts 82. Accordingly, the present invention provides a means of transporting
notes which does not require exact timing between respective components.
[0064] Still further, the present invention provides a transport wherein the direction of
movement of the notes may be changed without the requirement of physical guides which
typically are sites where jamming problems occur. In this respect, as best seen in
FIGS. 12A and 12B, the direction of note N is changed through its engagement with
a moving belt. No physical or structural guides are required to change the direction
of the note. The driving force of one transport and the transverse motion of belts
cause the note to change direction in a simple highly-efficient, reliable manner.
[0065] Each of these features is basically the result of a unique transport mechanism according
to the present invention which enables a note to be transferred without speed synchronization
between the respective transports, without physical guides to direct the note from
one transport to another, and without the need of surface contacting components. Importantly,
a transport according to the present invention facilitates simplification of other
mechanisms normally associated with media transfer devices. In this respect, a divert
assembly according to the present invention provides a sheet media dispensing device
wherein individual sheets may be diverted from a stacking mechanism during a stacking
operation. Typically, devices known heretofore would be required to "dump" a partial
stack if a bad bill (e.g. a "double") was introduced into the system. According to
the present invention, such a bill could be "diverted" from the stacking operation
without interfering with the partially completed stack. This is accomplished using
a divert assembly which is also operable to "dump" entire stacks of notes (in the
event the stack is not taken by a customer). The present invention thus provides a
media transport and handling device which is simpler in design and operation and has
operational advantages over systems known heretofore.
[0066] Although the invention has been described with respect to a preferred embodiment,
modifications will occur to others upon their reading and understanding of the specification.
For example, while the present invention has been described with respect to a stacking
device and mechanism for diverting bills to a "divert/dump location", a media dispensing
device can be provided utilizing a transport system as herein described without the
additional features. In this respect, FIG. 15 discloses a media dispensing apparatus
illustrating an alternate embodiment of the present invention wherein feed module
34 is combined with a transport module 800 having a horizontal transport 805 comprised
of a plurality of side-by-side parallel endless belts 810 aligned with juxtaposed
rails 820. Belts 810 are driven by a reversible motor 830. Depending on the direction
of belts 810, notes may be dispensed from either end of module 800.
[0067] It will also be appreciated that the media dispenser shown in FIGS. 1-14 could be
easily modified to dispense a stack of notes from the other end of transport module
38 to provide a "front" loading and dispensing devioe (FIGS. 1-14 show a "rear" loading
device). In this respect, one basically need only provide gate assembly 500 on the
other end of module 38 and program dispenser processor 18 to sequence and position
the respective components, primarily push plate 410 to accommodate for such a change.
In this respect, essentially all the components would function the same, but the back
side of push plate 410 Would push the stack of notes toward the dispensing opening.
Repositioning gate assembly 500 and reprogramming dispenser processor 18 would clearly
be within the ability of those skilled in the art upon a reading and understanding
of the present specification. Still further, while media dispenser 16 was described
as having two canisters 50, it will be appreciated that a media dispenser may have
more or less than two canisters without deviating from the present invention. These
and other modifications will occur to others upon reading and understanding of the
specification. It is intended that all such modifications and alterations be included
in so far as they come within the scope of the patent as claimed.
