[0001] This invention relates to an inker module for a postage meter mailing machine. Such
machines are used to imprint information on a sheet-like medium and, more particularly,
are used where the information imprinted on the sheet-like medium is related to a
variable parameter of the medium, for example imprinting a monetary value indicia
on an envelope wherein the value is correlative to the weight of the envelope.
[0002] In the mail processing field, it is most desirable for a system operator to be able
to deliver to mail processing equipment a batch of "Mixed mail", that is, the batch
is comprised of a large number of envelopes of varying dimensions, particularly, thickness
and weight. The ability of a mail processing system to process a large variety of
mixed mail eliminates the need of the system operator from performing the preliminary
steps of presorting the mail. It is further desirable for mail processing equipment
to be able to weigh the individual envelopes and affix the appropriate postage value
indicia in accordance with the envelope weight. It is generally considered advantageous
if the mail processing equipment can imprint a quality indicia upon envelopes varying
in thickness from that of a postcard to approximately a quarter (¼) of an inch (about
6 mm).
[0003] It is known to provide mail processing equipment comprised of a feeder for singularly
delivering envelopes in series to a transport assembly. The transport assembly deposits
the envelope on the scale for weighing. After a sufficient time to secure a true scale
reading of the envelope weight, commonly referred to as "weigh on the pause", the
transport assembly again assumes control over the envelope and delivers the envelope
to the mailing machine.
[0004] A mailing machine commonly comprises an integral transport assembly and an attached
rotatable print drum type postage meter. The mailing machine transport assembly assumes
speed control over the envelope performing any necessary speed adjustments required
to match the envelope's traversing speed with the imprinting speed to the postage
meter print drum to promote a quality indicia print. It is known for the postage meter
to include a value setting mechanism influenced by a scale which causes the postage
meter value setting mechanism to adjust the postage meter printing mechanism for printing
of the appropriate postage rate on the approaching envelope according to the envelope
weight as determined by the scale.
[0005] A mail processing system of this kind has as its primary objectives (i) the capability
to process a dimensionally wide variety of envelopes particularly with respect to
thickness and weight (ii) to process them as fast as possible in terms of envelope
per second and (iii) to process them while applying a high quality postal indicia.
Such a mail processing system has several limiting factors with respect to increasing
throughput relative to system cost. One such limiting factor is represented by the
time required in transporting the envelopes from one process station to another. Another
limiting factor is reflected in the time necessary to obtain an accurate weight from
the scale. While such factors as transport time and weighing time can conceivably
be decreased by incorporating advanced system techniques, the rule of diminishing
returns predicts that small improvements in system throughput by such an incorporation
would be achievable at disproportionate increases in system cost.
[0006] One possible alternative means of increasing the throughput of such mail processing
systems is to provide multiple scales and a suitable transport system such that the
scales are used alternatively. Such an arrangement would conceivably allow overlapping
of system processes to achieve a significant increased system throughput. However,
this alternative represents added cost from both equipment and system complexity standpoints.
[0007] In order for the mail processing equipment to accommodate the processing of packaged
mail, it is desirable to include a suitable mechanism within the mail processing equipment
having the capability to produce postage indicia printed tape strip which can be adhered
to packaged mail. Such a mechanism desirably should not detract from the processing
speed capability of the mail processing equipment for envelope mail.
[0008] It is an aim of the present invention to provide an inking mechanism of a generally
modular form integratable into a mailing machine for inking the printing elements
of a postage meter mounted to a mailing machine. The inking module is integrated into
the mailing machine so as not to detract from the speed capability of the mailing
machine whether it processes envelope mail or postage indicia tape.
[0009] In accordance with the present invention, there is provided an inking module, comprising:
an ink pad tray; and,
means for selectively positioning said ink pad tray in a retracted first position
and in an extended and elevated second position, said means to cause said ink pad
tray to travel from said first position to said the longitudinal projection of said
second position and subsequently thereto elevate to said second position.
[0010] The inking module of the present invention is particularly suited for employment
in a novel postage meter mailing machine having an increased throughput capability
in part resulting having a single process station whereat an envelope can be weighed
and a postage value indicia applied. The mailing machine includes a transport assembly
for properly positioning an envelope in the process station. The envelope is fed to
the mailing machine transport assembly by a suitable envelope feed apparatus, such
as a mixed mail feeder. After the envelope has been weighed and imprinted at the process
station, the transport assembly assumes control over the envelope again and ejects
the envelope from the mailing machine.
[0011] A mailing machine process station may comprise an integral scale suitably adapted
to accommodate the transport assembly, an optional envelope sealing assembly complementary
to the transport assembly, a vertically displaceable flat printing platen and a postage
meter support assembly for supporting a suitably attached postage meter. By employing
a multiple function processing station the mailing machine throughput is substantially
increased by facilitating minimum time lag between functional operations on each envelope
and eliminating the transportation time required by multiple process station systems.
[0012] Generally the scale is isolation mounted to the mailing machine base and includes
a plurality of slots in the weighing plate of the scale. The weighing plate has mounted
thereto a plurality of support members having a generally C-configuration. The support
members have mounted thereto an envelope clamping assembly which functions to clamp
an envelope to the weighing plate during weighing and to promote transport of the
envelope.
[0013] The transport assembly comprises a plurality of rollers independently supported by
the mailing machine base in a manner which permits the rollers to assume a vertically
engaged position (up position) in communication with the clamping assembly or a vertically
disengaged position (down position) out of communication with the clamping assembly.
Each roller is aligned to pass partly through a respective slot in its up position.
A bi-directional drive motor assembly is in communication with each roller via an
endless belt. The drive motor assembly includes a one way clutch interactive with
the transport assembly in such a way that motor actuation in a first direction results
in the endless belt imparting a driving force to each roller and motor actuation in
the second direction causes the transport assembly to reposition the rollers in the
second position.
[0014] The sealing assembly is mounted in the mailing machine in a suspended manner over
a portion of the weighing plate of the scale and includes a plurality of sealing members
selectively positionable in a first (downwardly-biased) position and a second (upwardly
retracted) position. In the first position, the sealing members are biased towards
respective ones of the transport rollers.
[0015] The preferred mailing machine further includes a vertically displaceable platen assembly
mounted to the base of the mailing machine and aligned to cooperate with a suitable
postage meter mounted to the postage meter support assembly.
[0016] The tape module includes a support means for supporting a tape track in a generally
cantilevered manner to extend generally below the meter module and located to one
side of the meter module. The tape module can be selectively positioned in a first
position such that the tape track is located longitudinally below and vertically between
the printing means of the meter module and the platen assembly. In a second position
of the tape module, the tape track is positioned longitudinally below and longitudinally
in spaced relationship to the printing means of the meter module and the platen module.
The tape module includes a tape feed which can selectively deliver to the tape track
one of two types of tape for imprinting by the meter module.
[0017] The cutter module includes a lever arm slidably mounted to a mailing machine support
wall traverse to the exit path of a tape strip from the tape module. The lever arm
rotatably carries a rotary cutter blade. The lever arm is driven in a reciprocating
motion by a crank.
[0018] The mailing machine further includes an inking mechanism for depositing ink on the
meter print elements. The inking module is located below a suitable postage meter
attached to the mailing machine. A drive motor having an output shaft and attached
gear is mounted in the mailing machine such that the gear is in constant mesh with
a linkage gear of the inking module. A linkage assembly responsive to the linkage
gear includes an ink pad tray in which an ink pad resides. Upon actuation of the drive
motor the linkage assembly is driven forwardly such that the ink pad tray is positioned
just below the register area of the meter and then is tilted upwardly, elevating the
ink pad tray into engaging contact with the register area of the meter.
[0019] Other capabilities and advantages of the present invention will be apparent or presented
in the following detailed description of the invention.
[0020] The invention will be better understood from the following non-limiting description
of an example thereof given with reference to the accompanying drawings in which:-

[0021] The postage meter mailing machine, in accordance with the present invention, employs
a novel modular architecture. That is, the mailing machine is comprised of sub-systems
which are not interdependent. Therefor, the mailing machine can be configured to include
only those sub-system modules necessary to meet particular operational needs for a
given application environment or, alternatively, the mailing machine can be configured
to include the full array of sub-system modules providing maximum application flexibility.
For example where the intended use is restricted to processing uniform mail, the scale
module, subsequently described, may be substantially omitted from the mailing machine
without affecting the system performance of remaining modules or the system controller.
[0022] Referring to Figures 1 and 2, a mailing machine, generally indicated as 11 and in
accordance with the preferred example of the present invention, employs a novel sub-system
modular architecture comprising a scale module 13, a transport module 12, a postage
meter module 15, a tape feed module 17, an inking module 19, and a platen module 21.
The modules are located within the mailing machine 11 such that the scale module 13
is located frontwardly of parallel support walls 33 and 35. The support walls 33 and
35 are fixed to the mailing machine base 30 in lateral spaced apart relationship.
Mounted to the base plate 30 between the support walls 33 and 35 is the ink module
19. Mounted above the ink module 19 to the support walls 33 and 35 is the postage
meter module 15. The platen module 21 is mounted to the base 30 just below a registration
portion of the postage meter 15, to be described more fully later. In addition, the
mailing machine has mounted to the wall 35 the tape feed module 17 coactive in the
preferred embodiment with a tape cutting mechanism 230.
[0023] Referring to Figures 1 and 3, the scale module 13 most suited for the present invention
is of the resilient type more fully described in our U.S. Patent No. 4 778 018 which
is specifically incorporated herein by reference. Briefly, the resilient type scale,
as described in the said Patent, utilizes the principles of harmonic vibration for
the purpose of determining the weight of an article. A flexibly mounted platform (inclusive
of members 37, 40, 43, 45, 47 and 49) is caused to oscillate by an initial excitation
action (not here shown). The frequency of the oscillation is primarily dependent upon
the total mass of the platform, and anything connected thereto, such as, envelope
residing on the platform, and the platform spring constant. As a result the mass of
an envelope residing on the platform can be determined and a weight assigned by comparing
the oscillation obtained subsequent to residence of the envelope with the known nominal
oscillation. For the purpose of brevity, the heredescribed portion of the scale module
13 represents that portion of the resilient type scale described in the said Patent
necessary to illustrate the scales' interrelationship with the mailing machine 11.
[0024] Referring particularly to Figures 1, 2 and 3, the scale module 13 includes a weighing
plate 37 supported by vertical beam members 40 at one of their respective ends. The
other end of each beam member 40 is fixed to a counter plate 42. The mailing machine
base 30 includes a plurality of scale support posts 36, each support post 36 including
a flexible member 34. Each member 34 is fixably mounted to the counter plate 42 in
such a way as to provide isolation mounting for the scale module 13 from the base
30.
[0025] The weighing plate 37 is generally rectangular in shape and includes a longitudinally
extending recess 38 formed along the rearward side of the weighing plate 37. Also
formed in the weighing plate are a plurality of colinearly aligned slots 41 (Fig.
1). A first generally C-configured clamp 43 is fixably mounted along the rearward
side of the weighing plate laterally to one side of the recess 38. A second generally
C-configured clamp 45 is fixed to the rearward side of the weighing plate 37 to the
other lateral side of the recess 38. A support beam 47 Figures 1 and 2 is mounted
at its ends to the respective clamps 43 and 45. Rotatably mounted by conventional
means to the support beam 47 is a plurality of clamping members 49 each of which is
mounted such that it is positioned over a respective one of said slots 41. Each of
the clamping members 49 includes a mounting arm 51 rotatably mounted to the support
beam 47 at one end and biased downwardly by any conventional means such as a spring.
The other end of the mounting arm 51 has fixably mounted thereto a generally arched
flange member 53 laterally sized to prevent the flange member 53 from venturing into
a respective slot 41.
[0026] It should be appreciated that if the weighing function is not desired to be included,
the scale module as aforedescribed may be eliminated. The only modification or substitution
necessary is the employment of a transport plate, of like construction to the weighing
plate 37, which transport plate can be fixed directly to mailing machine base 30 and
can include the clamps 43 and 45, support beam 47 and clamp members 49. The members
43, 45, 47 and 49, in the preferred embodiment of this invention, are maintained for
interaction with the transport module in a manner hereafter described.
[0027] It is noted that as viewed in Figures 1, 2, 3 and 4, the preferred embodiment of
the present invention includes a sealing module, generally indicated as 42. The sealing
module 30 is comprised of a generally L-shaped support member 44. The support member
44 is fixably mounted at one end to the mailing machine base 30. The other end of
the support member 44 rotatably supports a plurality of sealing members 46 biased
downwardly by a respective spring 48. The sealing members 46 are aligned longitudinally
in a generally staggered relationship and include tab 56. A solenoid 50 is fixably
mounted to the support member 44 such that the solenoid piston arm 52 abuts a portion
of a transfer link 54 slidably mounted to the support member 44. The transfer link
54 in parts abuts the respective sealing member tab 56. Actuation of the solenoid
50 causes the solenoid piston arm 52 to displace the transfer link 54 which thereby
causes the sealing members 46 to rotate to a spaced apart relationship to the weighing
plate 37 during the weighing process.
[0028] Referring to Figures 3, 4 and 5, the transport module 12 is comprised of a plurality
of first guide rollers 57 which are rotatably mounted to a frame 58 (best shown in
Figures 3 and 4). The frame 58 includes support seats 70, each seat 70 having a resident
seat 72. A plurality of generally L-shaped support members 74 are fixably mounted
at one end to the base 30 such that they do not interfere with the counter plate 42
of the scale module. The other end of the support member 74 is receive in a respective
seat 70 of the frame 58. Each support member 74 includes a seat 76 having a guide
pin 78 biased in the vertically upward direction by a spring 80 residing therein.
A portion of the guide pin 78 also, in part, resides in the seat 72 of the respective
frame seat 72.
[0029] Also rotatably mounted to the frame 58 is a plurality of rollers 61 positioned vertically
downwardly from and between a adjacent guide rollers 57. Fixably mounted by any conventional
means so as not to interfere with the operation of the scale module 13 to the base
30 of the mailing machine is a bi-directional drive motor 63 and associated drive
train, generally indicated at 65. An endless belt 69 is placed in driving communication
with the drive train 65 which includes a one way clutch arrangement, generally indicated
as 67. The endless belt 69 is positioned in a serpentine manner around rollers 57
and 61 thereby providing driving communication between the drive motor 63 and the
rollers 57.
[0030] When belt 69 is driven in the envelope feed direction of the mailing machine by the
drive motor 63 as permitted by the one-way clutch 67, the frame 58 will assume the
nominal or first position pursuant to the urging of the spring biased guide pin 78.
In the first position, the rollers 57 are positioned by the frame 58 to extend through
and slightly above a respective slot 41 in the weighing platform 37. When the belt
69 is driven in a reverse direction to the envelope feed direction, the one-way clutch
prevents continues displacement of the belt 69 causing the belt 69 to impart a downward
force on the frame 58 overcoming the biasing force of the springs 80. As a result,
the frame 58 is displaced downward to a second position causing the rollers 57 to
be withdrawn from the slots 41. It is noted that the drive train 65 includes a take-up
roller 66 biased in a conventional manner such that when the frame 58 is in the second
position the take-up maintains the belt 69 in a taut condition.
[0031] It is now apparent that when the rollers 57 are withdrawn from the slots 41, the
clamps 47 bias a envelope on the weighing plate thereagainst which facilitates the
weighing process. When the rollers 57 are journeyed partially into the slots 41, the
clamps 47 assist the transport function.
[0032] Referring to Figs. 1, 2, 4, and 12 and more particularly Fig. 6, as afore noted,
the postage meter 15 is mounted between the support walls 33 and 35. The postage meter
includes a forwardly located registration area, generally indicated as 82. Mounted
to the base 30 of the mailing machine just below the register area 82 of the postage
meter 15 is the platen module 21. The platen module 21 includes a support wall 81
fixably mounted the base 30. A plurality of C-brackets 83 and guide pins 85 are fixably
mounted to one face of the support wall 81 in vertical alignment to allow a platen
guide rod 87 to vertically slide along a defined vertical path. A platen guide rod
87 is laterally captured by the C-brackets 83 and guide pins 85 and has fixably mounted
to its top a platen plate 89. Also fixably mounted to the platen plate in laterally
spaced relationship is a first and second rack post 91 and 93, respectively. Fixably
mounted atop the platen plate 89 is a elastomeric material having a generally rectangular
shape of uniform thickness.
[0033] A drive motor 97 is mounted to and between parallel support brackets 99 such that
the rack posts 91 and 93 are outboard of the respective brackets 99. The drive motor
97 includes a drive shaft 101 which extends axially through the drive motor 97. At
each end of the drive shaft 101 is fixably mounted a gear 103 aligned to be in constant
mesh with a respective rack post 91 and 93. It is now appreciated that actuation of
the drive motor 97 can cause the rack post to elevate the platen plate 89 to bring
the elastomeric member 95 into engagement with a properly positioned envelope in the
meter register projection area and, in so doing, cause an indicia to be imprinted
on the envelope.
[0034] Referring now to Figs. 1, 7, and 12, the inking module 19 is located between the
support walls 33 and 35 of the mailing machine 25. A motor mounting plate 111 is fixably
mounted vertically to the base plate 30. A drive motor 113 is fixably mounted to the
motor mounting plate 111 such that the output shaft 115 extends through the plate
111. Fixably mounted around one end of the output shaft 115 outboard of the plate
111 is a gear 117. A second gear 119 is pivotally mounted to the base 30 in constant
mesh with gear 117. A linkage assembly comprised of a driving shaft or first link
121 is fixably mounted to the second gear 119 at one end. Fixably mounted along the
first link 121 is a second link 123 and a third link 125 in spaced apart parallel
orientation a fourth link 127 is pivotally mounted at its respective ends to a respective
link 125 and 123. A first and second transfer link 129 and 130, respectively, are
pivotally mounted in spaced apart relationship at one end to the fourth link 127.
Fixably mounted inboard to each of the support walls 33 and 35 is a first guide pin
135 and a second guide pin 137.
[0035] Each of the transfer links 129 and 130 extend respectively below a guide pin 135
and above a guide pin 137 such that the guide pins 135 and 137 act to guide the longitudinal
displaceable path, respectively, of the transfer links 129 and 130. The guide pins
135 and 137 also provide vertical support. Fixably mounted to the forward end of each
of the transfer links is a ink pad well 139 in which a ink pad resides (now shown).
At the other end of each of the transfer links 129 and 130 is formed a tilting surface
141. It can therefore be appreciated that upon actuation of the motor 113 the linkage
assembly is driven forwardly. The pins 135 are positioned such that when the ink pad
tray 139 is positioned just below the register area 82 of the meter 15 the tilt surface
141 are brought into forced engagement with the pin 135 causing the transfer links
130 and 129 to be tilted upwardly elevating the ink pad well 139 into engaging contact
with the register area 85 of meter 15.
[0036] Referring now to Figs. 1, 4, 8, 9, 10, and 12, the tape module 17 is slidably mounted
to the wall 35 along a track 150 formed along the outboard side of the wall 35. The
tape module consist of a rail 151 which is slidably mounted longitudinally to track
150 to define the longitudinal displacement path of the tape module 17. A bracket
155 is fixably mounted to the rail 153. A second bracket 157 having a generally vertically
extended slot 159 is slidable relative to track 150 and is connected to the bracket
155. The bracket 155 includes a back wall 161 which has mounted thereto a first tape
drive motor 163 and a second tape drive motor 165. The bracket 1 55 includes a first
set of longitudinally aligned bracket flanges 167. Pivotally mounted to each of the
flanges 167 is one end of a first pivot arm 169. The bracket 155 further includes
a second set of bracket flanges 171 which, in like manner, has pivotally mounted thereto,
respectively, one end of a second pivot arm 173. The other end of each pivot arm 169
and 173 is pivotally mounted to a tape guide housing 175.
[0037] The tape guide housing 175 has an entrance 177 aligned opposite an exit 179. Fixably
mounted in a cantilever fashion to the tape guide housing 175 to extend outwardly
from the exit 179 of the tape guide housing 175 is a tape track 181 having a wedged
shape feed member 183 extending partially into the tape guide housing 175. The tape
track 181 and the feed member 183 are mounted to the side walls of the housing 175
to laterally extend across the exit 179. It is noted that the tape track 181 is comprised
of a first and second channeled side walls 174 and 176, respectively, having a strip
member 178 supported by and longitudinally between the side walls' channel (ref. to
Fig. 7a). Rotatably mounted in the tape guide housing 175 is a first and second tape
drive roller 185 and 187, respectively. Rotatably mounted in the housing 175 opposite
the first drive roller 185 is a first idler roller 187 and, in like manner, a second
idler roller 191 is rotatably mounted opposite the second tape drive roller 187. A
flexible shaft 193 communicates the first motor 163 to the first tape drive roller
185 and, in like manner, a second flexible shaft 195 communicates the second tape
drive motor 165 with the second tape drive roller 187.
[0038] The housing 175 further includes a flanged portion 197 having fixably mounted thereto
a plurality of first guide pins 198 and a plurality of second guide pins 199. A dual
tape support assembly 200 is fixably mounted to the base 30 and rotatably supports
a first and a second roll of tape 203 and 205, respectively. The first roll of tape
203 is threaded such the the guide pins align the tape 203 for journey into the housing
175 and tape track 181. The tape 203 is located in the tape track 181 so as to be
captured between the channeled side walls 174 and 176 resting on the strip 178. As
shown in Fig. 8 and in accordance with the preferred embodiment of the invention,
the tape 203 is a backing tape supplied with sufficient backing lead such that the
backing 180 will extend in a reverse direction below the strip 178 to and between
the idle roller 191 and the drive roller 187 such that actuation of the drive roller
187 on the tape backing 180 causes the tape 203 to be advanced and the backing pealed
away. The tape 205 is journeyed around the pin 198 to pass between idle roller 198
and drive roller 185 and into the tape-track 181 to rest on the tape 203 and captured
between the channeled side walls 174 and 176.
[0039] Optionally, it may be desired for the tape 203 to be of the non-backing type. As
indicated in phantom in Fig. 9, the tape can be optionally threaded directly between
rollers 187 and 191 of the track 181.
[0040] Referring more particularly to Figs. 10 and 12, the tape module 17 is slidable along
a track 150 formed formed in wall 35 pursuant motivation of second bracket 157. It
is noted that the tape module 17 is so positioned relative to the registration area
80 of the postage meter 15 and the platen module 21 such that the track 181 is located
in a first position between the postage meter registration area 80 and the platen
module 21. In a second position the track 181 is repositioned below the postage meter
15 clear of platen plate 89 travel. The position of the track 150 dependent upon the
location of the second bracket 157.
[0041] In order to motivate the second bracket 157 and, in turn position the track 181 in
the first (as indicated in phantom in Fig. 12) or second position, a motor 210 is
fixably mounted to the mailing machine base 30. Fixably mounted around the output
shaft of the motor 210 is a pulley 212. Rotatably mounted to the wall 35 is a double
pulley assembly 214 which includes a first pulley 216 and second pulley 220. The first
pulley 216 is in driven communication with the motor 210 through an endless belt 218
journeyed between the pulleys 212 and 216. A crank assembly 222 is rotatably mounted
to the wall 35 and includes a pulley 224 in driven communication with the pulley 220
of the pulley assembly 214 through an endless belt 226. The crank assembly 214 also
includes a crank arm 228 having a slide pin 230 residing in the slot 159 of the bracket
157 of the tape module 17.
[0042] Motivation of the tape module 17 along the track 150 is accomplished by causing the
motor 212 to rotate the pulley 212 in the direction shown in Fig. 10. The rotation
of pulley 212 is transferred to pulley 224 of the crank assembly 222 through the double
pulley assemble 214 by belts 218 and 216. The rotation of pulley 224 through one-half
revolutions causes the tape module 17 to displace from the first position to the second
position. Further actuation of the motor 210 causes the pulley 224 to further rotate
to complete the revolution resulting in the tape module returning to the first position.
[0043] Referring to Fig. 11, the mailing machine may further include a tape cutter module
230. The tape cutter module 230 is comprised of dual track 232 mounted outboard of
the wall 33. A member 234 is slidably mounted to track 232. A lever arm 236 having
a vertically directed slot 238 is fixably mounted to the member 34. The lever arm
236 includes a portion 240 which extends in a horizontal cantilevered manner and has
a rotary blade 242 rotatably mounted to the end of the lever portion 240. A cutter
beam 244 is mounted to the wall 33 to cooperative act with the rotary blade 242.
[0044] Actuation of the cutter module 230 is provided by the motor 210. When the mailing
machine includes the cutter module 230 as described in the preferred embodiment, the
double pulley 214 is comprised such that in a first direction (as shown by the arrows
in Fig. 10) displacement of pulley 216 is directly transferred to the pulley 220 without
causing the shaft 246 to rotatably respond. Displacement in the opposite direction
of the pulley 214 caused by reverse drive of motor 210 result in pulley 214 rotating
the shaft 246 while pulley 220 remains stationary. The pulley 214 and shaft 246 arrangement
can be of a conventional slip double pulley construction.
[0045] The shaft 246 extends longitudinally to and is rotatably mounted in a support member
248 fixably mounted to the base 30 of the mailing machine. Fixably mounted around
a portion of the shaft 246 generally adjacent to the member 248 is a crank arm 250.
The crank arm 250 includes a pin 252 slidably captured in the slot 238 of the lever
arm 236 such that upon initial one-half rotation the motor 210 in the reverse direction,
acting through the double pulley shaft 246 causing the lever arm 236 to be displaced
by the crank arm pin 252 to a second position (indicated in phantom in Fig. 11). Further
actuation of the motor 210 in the reverse direction causes the pulley 224 to further
rotate to complete the revolution resulting in the rotary cutter blade in coaction
with the beam 244 to cut a tape 205 segment ejected the past.
[0046] It is intended that the mailing machine 11 operate such that the transport module
12 receives a envelope from a suitable feed mechanism (not shown) The transport system
properly positions the envelope on the weighing plate relative to the meter module
15. The transport rollers 57 are then caused to withdraw, in the manner aforedescribed,
under the influence of the motor 63. Simultaneously, the inking module 19 has been
actuated, in the manner aforedescribed, to apply imprinting ink to the registration
area of the postage meter module 15 and withdrawn to the first position prior to the
arrival of the envelope. Upon the arrival of the envelope in proper position at the
process station and withdrawal of the transport rollers 57, scale module 13 will weight
the envelope, in a manner described in U.S. Patent No. 4 778 018 and inform the
meter for meter setting, in a manner described in co-pending U.K. Patent Application
(Ref: N 501 6) filed October 26th, 1988, entitled PRINTWHEEL SETTING DEVICE FOR A
POSTAGE METER. Subsequent to weighing of the envelope the platen module 21 is actuated,
in the manner as aforedescribed, to result in the imprinting of an indicia on the
envelope. Simultaneously with actuation of the platen module 21 or pursuant to a minimum
time lag, the transport module 12 can be reactivated or further activated to return
the rollers 57 to their first position. Upon obtainment of the first position of the
rollers 57, the envelope is discharged from the mailing machine. Simultaneously with
commencement of discharge of the process station envelope from the process station,
a new envelope may be received by the transport module 12.
[0047] In the preferred embodiment of the present invention, the tape module 17 can be positioned,
in the manner aforedescribed, for imprint of a indicia on one of the tapes 203 or
205 carried by the tape module 17. It is noted the vertical elevation of the tape
track 181 is below the vertical position of the ink pad well 139 such that the tape
track 181 does not interfere with the operation of the inking module 17.
[0048] Should it be desired to imprint an indicia on the tape 205, it is the only necessary
to actuate the platen drive motor 97. Inking can then occur after each cycle of the
platen drive motor 97. Subsequent to imprinting, the tape drive motor 163 to cause
the indiced portion of the tape 205 to be ejected and cut, in a manner as aforedescribed,
by the cutter module 203. In order to imprint on tape 203, the described is again
followed with the exception that prior to imprinting the tape 205 is drawn in a reverse
direction by the taped drive motor 163 to expose the tape 203 to the meter register
area. The indiced tape portion of tape 203 being ejected under the influence of tape
drive motor 165.

described in its preferred embodiment and in its preferred environment and the particular
description and the drawings should not be taken as limiting.
