referring to fig1 the preferred embodiment of the card package production system printer 100 of the present invention is seen to include a free standing printer module 102 and a card attachment module 104 . referring to fig2 the printer module prints card holder name and address and other account information 106 , on one of three panels 108 , 110 and 112 of a paper sheet carrier 113 , such as the middle panel 110 . the three panels are defined by two pre - weakened fold - lines 114 and 116 . the printer module also prints a bar code 120 representative of information concerning the account on another of the panels , such as the end panel 112 , such as the account number and the number of cards that are to be attached to the carrier 113 . the printer module is controlled by a computer ( not shown ) and controller , described below . the printer preferably prints carriers at a minimum speed of 32 / minute and has a resolution of no less than 300 dpi × 300 dpi . the normal speed of operation is approximately 2000 carriers per hour , or approximately thirty - three carriers per minute . the printer module 102 may be a model play plex printer made by olympus , or equivalent . the details of the printer module form no part of the present invention but reference may be made to operator &# 39 ; s guide for the above identified model ms32nss published by olympus . the operation is described pursuant to the example of the card holder information 106 being located on panel 108 and the bar code 120 being mounted at the location shown on panel 112 . however , the printer is capable of printing both the card holder information 106 and the bar code information 120 at other selected locations on the carrier 113 . the card attachment module 104 is capable of reading the information at other informational locations on the carrier 113 than the example shown in fig2 . the printed carriers 113 from the printing module 102 are passed to the attachment module 104 by means of an inter - module carrier guide 122 . the inter - module carrier guide is better seen in fig5 . referring to fig5 the guide 122 passes carriers 113 from an outlet 124 of the carrier printer module 102 to a carrier inlet 126 of the attachment module 104 . referring to fig1 - 4 , the attachment module takes cards from a stack of pre - embossed cards 128 ′ from a card picker assembly 140 and attaches the pre - embossed cards 128 , such as embossed and / or magnetically encoded credit cards , encoded chip cards , r / f cards , etc . to the carrier 113 at one or more locations 130 and 132 or on like locations on one or more or all of the three panels . it then folds the carrier , as shown in fig3 to form a card package 115 . the details of the card picker assembly forms no part of the present invention , and preferably is substantially the same as the one shown in u . s . patent application of bretl et al ., ser . no . 09 / 081 , 312 , filed may 19 , 1998 , and entitled “ card package production system with a multireader card track and method ”, which is hereby incorporated by reference . the cards 128 generally have an account number and an account holder &# 39 ; s name embossed on the card and the same information encoded on a magnetic stripe on the back of the card 128 . additional information , such as the number of cards to be attached to the carrier may also be contained in the bar code . in addition , the back of the card has the account number and account name encoded in bar code printed on the back of the card . this information is checked for proper encoding and if the coding is not correct or if the coding does not match the encoded information of a carrier to which it is to be attached , the card 128 is passed through the attachment module 104 to a card reject bin 134 . other wise the cards 128 are attached to the matching carrier 113 to form the card package 115 , and the card packages 115 are passed to a card package distribution module 136 for distribution in three different ways depending upon circumstances . in one case , if the card packages 115 are unacceptable due to having too many cards , not enough cards or cards in the wrong location , then they are passed to a card package reject bin 142 . if the card package is correctly prepared and is to be passed directly along a primary card package transport path to an envelope stuffing machine ( not shown ), such as a model series 5 envelope stuffer made by pitney boewes , then the card packages are passed directly to the envelope stuffer through a primary card package outlet 144 . otherwise , the card package 115 is passed to a fifo card package stacker 146 to form a stack of card packages 115 ′. the card package stacker 146 illustrated in fig1 is the one shown and described in detail in the parent application of this continuation - in - part application cited above . reference should be made to the parent application for any details of the operation of the card package production system 100 other than the operation of the stacker 200 and distribution module 202 of which it is a part . referring to fig3 and 4 , the card 128 is attached to the carrier 113 by means of an adhesive label 148 . one side of the adhesive label 148 is attached to the card by a heat activated adhesive , such as releasable adhesive made by maple roll , a division of itw . the other side of the label is attached to the carrier by means of a permanent adhesive . the labels are adhered to a roll of backing paper tape by the permanent adhesive . preferably , the adhesive labels 148 are those made by maple roll note above , or the like . as illustrated in fig4 when the card 128 is lifted off the carrier 113 , the adhesive label 148 remains attached to the carrier 113 and does not adhere to back 128 ′ of the card 128 . this is because the attraction of the permanent adhesive to the carrier 113 is stronger than the bond between the heat activated adhesive and the back of the card and , because in keeping with one aspect of the invention only a middle section of the label is heat activated to provide a “ dead zone ” of nonactivated adhesive at opposite ends of the label 148 . advantageously , once the heat activated label 148 is removed from the back 128 ′ of the card 128 , the heat activated adhesive losses its adhesive qualities unless it is again heated to the necessary minimum activation temperature of approximately 160 - degrees fahrenheit . as seen in fig1 the housing 104 has a flat top on which a computer display monitor 152 and a computer keyboard 154 of the computer ( not shown ) are supported . the computer is protectively contained within the housing section 161 . the computer housing section 161 has a hinged door to enable access to the computer . preferably , the computer that is used to control the card package production system 100 including the attachment module 104 is a model presario computer made by compaq having a minimum processor speed of 333 mhz and a minimum hard drive memory capacity of 4 gb , or the like . the computer controls all of the automatic operations of the attachment module 104 and the printer module 102 , and operated the distribution module in accordance with the flow charts of fig1 a and 17b . referring to fig5 the inter - module guide 122 is aligned with a carrier transport path 164 that extends straight from the carrier inlet 126 toward the card package distribution module 136 . however before the carrier reaches the card package distribution module 136 , it intersects at a right angle with the card transport path 166 that extends from the card tray 140 to an intersection 168 with the carrier transport path 164 . at the intersection 168 , the card attachment station attaches the card or cards 128 to the carriers . the carriers with attached cards are then folded at a folding station to form card packages 115 . the card packages 115 then move along a card package transport path 170 to the card package distribution module 136 and distributed according to the circumstances note above . the card transport path is elevated relative to the carrier transport path and the cards are dropped onto the carriers for attachment . if rejected and not attached , they proceed past the card attachment station along a card reject transport path 172 to the card reject bin 134 . referring to fig6 and 8 , particularly fig7 as the carrier form 113 with one or more attached card 128 enters a second fold station 202 in the card package production module 104 , the carrier form 113 pushes down a lever 204 . a photo - sensor 206 is mounted beneath the lever 204 , and when the lever 204 is in the normal , or up , position as shown in solid line in fig7 light to the sensor 206 is blocked by the lever 204 . however , when the lever 204 is pushed down by the carrier form 113 , the light is unblocked , and the sensor 206 detects light from its associated infrared light source . the computer 198 then responds to the sensor 206 to energize the second fold drive motor . if the particular card package 115 has been identified by the computer 198 as one to be stacked rather than to be passed along the primary card package path to primary card package outlet 144 and to the envelope stuffer 200 , fig5 opposite the primary card package outlet 144 , then simultaneously with the card package 115 being sensed and the second fold motor being turned on , the computer 196 causes the stacker solenoid 210 to be energized to pivot upwardly a stacking platform 212 of a stacking gate assembly 214 to pass the folded card package 115 to the stacker assembly 146 . this position of the stacker gate assembly 214 is illustrated in fig9 and 10 . in fig9 a first card package 115 is in a stacker loading position in which its leading edge is protruding outwardly from a lateral facing card package receiving slot 145 at the bottom of the stacker 144 and hanging over an edge of a horizontal section 240 of a card package support member 242 having an upwardly slanted ramp section 244 while the next card package 115 ′ is being moved into position . once the carrier package 115 has passed through the second fold station 202 , the lever 204 is allowed to fall back down to a sensor light blocking position , and the computer 198 responds to this condition by energizing a transport motor 216 that drives the pinch rollers 218 , and the card package 115 starts being pulled through the pinch rollers 218 . as the card package 115 is pulled though the rollers 218 , the card package 115 blocks passage of infrared light to a stacker sensor 220 . when this occurs , the computer 198 responds to actuation of the sensor 220 to immediately turn on the stacker motor 222 that drives the pinch rollers 224 . as the card package is pulled through the pinch rollers 224 , the card package 115 passes by the stacker sensor 220 . in response to this event , the computer 198 causes both of the stacker motor 222 and the transport motor 216 to turn off to remove drive from the associated pinch rollers . the first card package 115 is then left in the position shown in fig9 and 10 in which it is only partially inserted into the stacker 146 . as seen in fig1 , when the next card package 115 ′ is driven up the ramp 242 it engages the underside of the first card package 115 adjacent the lagging edge . then the card package 115 ′ is advance to the position previously held by the first card package 115 , and the first card package is moved entirely into the card stacker 146 and resting on the bottom 149 of the stacker 146 , as shown in fig1 , with the leading edge 244 of the second card package 115 ′ underlying the lagging edge 246 and being partly received within the inlet slot 145 and supported by the bottom 149 of the stacker 146 . this process is repeated for the insertion of subsequent card packages 115 with each one being interleaved with an earlier card package before being fully inserted into the card stacker , and with each earlier card package being moved fully into the card stacker at the same time a subsequent card package is being moved into the card stacker loading position , as shown in fig1 and 13 . in fig1 , a third card package 115 ″ has not been selected for stacking and the stacking gate has been left in it lower non - stacking position to pass the third card package to the primary card package path on support platform 248 . if the card package 115 ″ is not rejected then it passes through the series of rollers 229 , 234 and 238 to the outlet 144 , as shown in fig1 and 15 . if the computer 196 senses that there is something wrong with the card package 115 such that it should be rejected and not stacked , then the stacker gate solenoid 210 is not energized in response to the lever 204 being pushed down by the card package . consequently , the card package is not directed to the stacker assembly 146 by the guide platform 212 of the stacker gate 214 that remains in a lowered non - stacking position as shown in fig7 . consequently , the card package 115 passes across the platform 212 straight through to pinch rollers 226 . as the card package is pulled trough the pinch rollers 226 it interrupts the light to a photo sensor 228 . this causes the computer 198 to energize the reject solenoid 210 that lifts the reject platform 230 of the reject gate to be pivoted to an elevated reject position . this causes the card package to be deflected downwardly into the reject hopper 142 . after a pre - selected time after the lagging edge of the card package passes the photo - sensor k , such as one - half second , the computer 198 turns off the transport motor 216 . this reject operation is illustrated in fig1 . it should be appreciated that if a card designated for stacking is to be rejected the stacker gate remains down so that it passes through the primary card package path to reach the reject gate and the reject bin . one of the reasons that a card package may be rejected is because the number of cards in the card package is less or more than the number of cards designated for the card package . this is determined by measuring the thickness of the card package with electronic thickness measuring gages 250 , 252 and 254 that are mounted to a pivot arm 256 . normally , the gages rest on the top surface of the card packages as they pass underneath . referring to fig8 in keeping with one aspect of the invention if an envelope inserter , or stuffer , 200 , fig5 is employed and attached to receive card packages 115 from the primary card package outlet 144 , then when a card package 115 is intended for the envelope stuffer 200 , the stacking gate 214 is left in its non - stacking lowered position as shown in fig7 and the card package 115 , if not being rejected , is passed over the reject platform 232 and passed through a series of rollers 234 and 236 to the outlet 144 . when the lagging edge of the card package 115 has cleared a sensor 238 , the transport motor 222 that drives the rollers 236 and 238 is turned off . this is illustrated in fig1 , 14 and 15 . the controller , or computer , 198 can be any computer capable of controlling the card attachment and distribution functions of the card package production system . the control system preferably includes an opto 22 model controller system made by opto 22 of temecula , calif . and having a web site at www . optto22 . com . the optocontrol system has two brain boards that interface an lcsx controller with a plurality of control modules . the control modules interface with the sensors and the control motors . the controller , in turn , operates in accordance with the optocontrol programming flow chart . pursuant to the optocontrol , the optocontrol software automatically generates the code needed to effectuate the flow chart . referring now to fig1 a and 17b the operational routine flow charts for operation of the distribution module and the operation of the stacker in particular are shown . the flow charts are compiled and entered into a software designer program to generate a source code used to control mechanical devices such as the preferred embodiment . the software designer program is called “ optocontrol ” manufactured by opto 22 . instructions on the use of this software and the flow chart conventions and protocol can be found in the optocontrol user &# 39 ; s guide , form number 724 - 990831 - august , 1999 ; the optodisplay user &# 39 ; s guide , form 23 - 990831 - august , 1999 ; and the optocontrol command reference , form number 725 - 990831 - august 1999 , all of which are hereby incorporated by reference . if other details are desired concerning the control computer 198 and the control system of which it is a part , parent of this application and the above provisional patent application on which it is based . referring to fig8 a belt drive assembly 250 for driving the card packages 115 to the primary card package outlet is shown in a raised position to which it has been pivotally moved about pivot axis 249 for purpose of facilitating access to the carrier packages to clear a jam . while a particular embodiment has been shown and described above , it should be appreciated that there may be many variations within the scope of the invention as defined in the appended claims .
