Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling the operation of a card issuing device used in a convenience store or the like to issue various cards, for example, a prepaid card such as a telephone card.

[0002]

2. Description of the Related Art With the spread of prepaid cards represented by telephone cards in recent years, various card issuing devices for handling thin and flexible cards have been proposed and put into practical use. As an example, see, for example, Japanese Utility Model Laid-Open No. 5-92.
Referring to Japanese Patent Publication No. 876, an issuing device in which about 50 prepaid cards of different types such as face value and pattern are stored in advance in a plurality of card cassettes, and these card cassettes are covered with a common opening / closing door. The card is set in advance in a cassette mounting portion in the main body, and when a card issuance request is made, one card is taken out of a card cassette containing a target card by a pickup roller and is issued from a card issuing port. There is something like that. Each card is stored in a sealed card cassette,
In addition, setting the door in the cassette mounting section in the main body of the issuing device and closing it with the keyed door prevents the key of the door from being operated directly by anyone other than the person in charge, so that the card can be removed, stolen, and other financially. This is to eliminate trouble occurrence factors as much as possible. With respect to a card cassette for storing a plurality of cards in a stacked state, a narrow slit-shaped card outlet for taking out only one card is formed at an end face of a rectangular box-shaped case main body. In general, the card is ejected through the card. A roller entry opening is formed on one surface of the case body of the card cassette so that the pickup roller enters the card body so as to come into contact with the topmost card in the case body.

In such a card issuing apparatus, when looking at the configuration around the cassette mounting section, a mounting section for mounting the card cassettes in a stacked state is formed, and a pickup means including a pickup roller for each card cassette is provided. They are arranged individually. Therefore, only one target card is taken out from the card cassette by rotating the pickup roller corresponding to the target card cassette by bringing the pickup roller into contact with the card by the solenoid, and is issued from the corresponding card issuing port.

[0004]

However, according to such a card issuing apparatus, since a pickup roller and a card issuing port are provided for each card cassette, there is a restriction in filling the space between the cassettes. The mounting section becomes large, which hinders downsizing of the entire device. Especially,
The types of cards handled by one card issuing device have increased,
For example, when dealing with cards of ten or more types, an increase in the size of the multi-layer structure is inevitable, the number of required components is large, and the device becomes large.

[0005] In some cases, only one card issuing port is used in common for all cards to reduce the size. That is, the image forming apparatus has a structure in accordance with the paper feed structure from the multi-stage paper feed cassette, and each pickup roller and the rollers and belts of the common transport path of each card cassette are simultaneously rotated, so that the target card cassette By energizing only the corresponding solenoid and bringing the corresponding pickup roller into contact with the card for a certain period of time, it is possible to take out the cards one by one. However, when a plurality of rollers and belts are combined to form a transport path from each card cassette to a common card issuing port, and a card is issued from a card cassette mounted farthest from the card issuing port. In this method, the card sequentially passes between a plurality of rollers, between belts, and the like, so that the card is rubbed or damaged more than necessary in the meantime, and the information stored in the card is lost. . In this,
Defective products are issued, and the reliability as a card issuing device is lacking.

Therefore, development of a new card issuing device which can reduce the number of parts without increasing the size of the stacked structure even when a large number of card cassettes are stacked is desired. Therefore, the present invention provides an operation control method for a card issuing device that can easily perform an adjustment work required for reliable operation of the card issuing device before shipment when the card issuing device is developed. The purpose is to do.

[0007]

According to the first aspect of the present invention,
A cassette rack in which a plurality of card cassettes, each of which accommodates a plurality of cards so as to be able to be taken out, is individually drawn out, is formed in a stacking direction, and is housed in each of the cassette housing sections of the cassette rack. A cassette withdrawal device for selecting a desired card cassette from a plurality of card cassettes and pulling out the card cassette from a corresponding cassette storage unit; A card removal device including a pickup roller, a carrier unit on which the card removal device including the pickup roller and the cassette removal device are mounted, and which is movable across the entire range of the card cassette in the stacking direction; Directly moving the carrier unit by control A carrier device that has a servomotor and conveys the taken-out card to a card issuing port while holding the card, and a reference position sensor for determining a reference point of movement of the carrier unit. In the operation control method, before shipping, the carrier unit is moved in advance to measure a length from a reference point by the reference position sensor to a pull-out position of each card cassette stored in the cassette storage unit. The measured value is stored in a memory as a movement amount of the carrier unit, and when the carrier unit is moved to a target card cassette during use, the detection output of the reference position sensor and the information stored in the memory are used. Is used to determine the amount of movement.

Accordingly, one carrier roller common to all card cassettes is mounted on a carrier unit movable over the entire range of the stacked card cassettes,
The card is moved to the position of the target card cassette, the card cassette is pulled out by the cassette drawer, and the card can be taken out by the pickup roller of the card takeout device,
In a new card issuance method in which a card is issued by transferring a removed card to a card issuance port by moving a carrier unit, a reference position sensor is used to determine a reference point for moving the carrier unit to a target card cassette position. The detection point of this reference position sensor may be different for each product due to sensor mounting errors and variations in sensor characteristics.If this is the case, move the carrier unit to the target card cassette position and pull it out. Before shipment of the product, the carrier unit is moved in the stacking direction of the card cassette to measure the length from the reference position sensor to the card cassette withdrawal position, and the actual measured value is used. Is stored in the memory as the movement amount of the carrier unit, and the actual When the carrier unit is moved to the position of the target card cassette during use, the physical position of the reference position sensor is controlled since the carrier unit is moved from the position of the reference position sensor by the amount of movement based on the information stored in the memory. Without individually adjusting the position of the reference point for moving the carrier unit substantially in accordance with the state peculiar to the apparatus. Withdrawal operation can be performed.

According to a second aspect of the present invention, the cassette extracting device is selectively engaged with a slider which reciprocates in a card cassette extracting direction and a recess integrally formed with the slider and having the same shape for each card cassette. 2. The operation control method for a card issuing device according to claim 1, further comprising a claw body that is detachable, wherein the cassette rack has a draw-out groove for moving the claw body in a draw-out direction for each cassette storage unit. At the time of length measurement from the reference point to the drawing position of each card cassette before shipping, the carrier unit is manually moved from the reference point to the target card cassette position, and the claw body is aligned with the corresponding drawing groove. By driving a DC servo motor to slightly reciprocate the carrier unit in the laminating direction, the amount of movement of the claw body in the drawing groove is calculated and the drawing is performed. By identifying the center position of the inner,
The measured value was a measured value from the reference point to the drawing position of the card cassette.

Therefore, the draw-out groove formed in the cassette rack has a slight gap in the cassette stacking direction with respect to the claw body in order to facilitate movement of the claw body in the cassette drawer. Since the position where the claw body is at the center position of the draw-out groove is taken as the actually measured value in consideration of the gap in the draw-out groove, at the time of actual use after shipment, the carrier unit is moved to the draw-out position of the target card cassette, and When the cassette is pulled out, the claw body moves smoothly along the center position of the draw-out groove without generating a bias such that the claw body moves by rubbing one side of the draw-out groove.

According to a third aspect of the present invention, in the operation control method of the card issuing device according to the first or second aspect, the reference position sensor is disposed at one end in the card cassette stacking direction, and the card cassette is moved from the reference point before shipment. Is performed only for the card cassette withdrawal position farthest from the reference position sensor, and the amount of movement from the reference point to another card cassette withdrawal position is calculated by calculation based on the actual measurement value. did.

Therefore, if the distance accuracy between the drawing positions of the card cassettes can be assured after assembling the cassette rack, only the length measurement from the reference point to the drawing position of the farthest card cassette is performed, and the other card cassettes are measured. By calculating the amount of movement to the pull-out position based on the above-described measured values, the operation before shipping can be simplified.

In the apparatus body 10, a card issuing port 70 is formed at the highest position corresponding to the transport roller 53.

B. Basic Operation In such a basic configuration, when the host issues a command to issue a certain card 1, a desired card cassette 2 containing the target card 1 is selectively pulled out from the cassette rack 15. This is performed by the cassette drawer 40. First, by moving the carrier unit 33 in the vertical direction via the timing belt 37 by driving the carrier motor 11, the operating section 45 such as the slider 43 is positioned in the cassette storage section 18 in which the target card cassette 2 is stored. . At this time, since the pull-in pin 44 moves up and down in the vertical common groove 23 and the concave portion 6, it does not hinder the vertical movement of the carrier unit 33 on which the slider 43 is mounted. When the cassette conveying pulse motor 12 is driven at the position of the target card cassette 2 to rotate the round shaft 31 and the gear 46, the slider 43 slides forward. At this time, since the draw-in pin 44 that moves in the draw-out groove 22 integrally with the slider 43 is locked in the concave portion 6, the draw-in pin 44 slides the target card cassette 2 forward from inside the cassette storage portion 18. Then, the card cassette 2 is set in a drawn-out state in which the leading end side protrudes from the cassette rack 15 (see FIG. 10). The solenoid 59 is energized before the card cassette 2 is pulled out, and the pickup roller 51 is set to the retracted position so as not to hinder the drawing of the card cassette 2 to a position corresponding to the pickup roller 51. The position is controlled (see FIG. 9). Therefore, the carrier unit 33 is moved up and down by the carrier motor 11 and stopped at a position corresponding to the target card cassette 2, and the cassette transport pulse motor 12 is driven to move the target card cassette 2 to the cassette rack 15. Can be pulled out a little.

When the target card cassette 2 is pulled out from the cassette rack 15, one card 1 is taken out from the card cassette 2 by the card take-out device 50. First, when the target card cassette 2 is pulled out to a predetermined position, the solenoid 59 is de-energized, and the pickup roller 51 enters the roller entry opening 5 and contacts the uppermost card 1 in the card cassette 2. (See FIG. 11). At this time, the pickup roller 51 receives the pressing force of the spring 60, so that the pickup roller 51 comes into pressure contact with the card 1. By driving the card conveying pulse motor 13 in parallel with this operation, the pickup roller 51 is driven to rotate via the round shaft 32, the bevel gears 65 and 64, and the gear train 66. As a result, the top card 1 receives the repetitive output from the pickup roller 51 which is in contact with the rotating card while rotating, and is taken out of the card cassette 2 from the card ejection port 4 (see FIG. 12). The card 1 taken out is further transported by being transported by the transport roller 52 rotating at the same time. When the removed card 1 is in a state of being conveyed by the conveying roller 52,
The solenoid 59 is energized to prevent double feeding, and the rotating pickup roller 51 separates to the retracted position (see FIG. 13). Further, the cassette transport pulse motor 12
Is driven in reverse, and the operation of returning the card cassette 2 that has been pulled out to the original position in the cassette storage portion 18 is performed by an operation reverse to the operation performed when the cassette drawer 40 is pulled out (see FIG. 14). When the card 1 receiving the transfer force by the transfer roller 52 reaches the transfer roller 53 side, the transfer force is continuously received. However, the front end of the card 1 faces directly upward and the rear end side does not come out of the transfer roller 53. As a result, the card transport pulse motor 13 is stopped, and the card 1 is held by the transport roller 53 while being directed upward while being guided by the guide plate 61.

One card 1 by the card removal device 50
Is completed, the carrier motor 11 is driven again, and the carrier unit 33 is moved to the target card cassette 2 again.
Is moved upward from the position to the uppermost position.
Therefore, the card 1 held by the transport roller 53
Card issuance slot 7 with the movement of carrier unit 33
Transported to zero. As a result, the leading end of the card 1 is exposed to the outside through the card issuing slot 70, so that the card 1 can be pulled out by hand and the card 1 is issued.

As described above, the plurality of card cassettes 2 are simply stacked using the cassette rack 15, and the target card cassette 2 is pulled out of the card cassettes 2 by the cassette drawer 40, and According to the configuration in which only one card 1 is taken out from the inside by the card take-out device 50 and the taken-out card 1 is conveyed by the carrier unit 33 to the card issuance port 70 to be issued between the card cassettes 2 in the stacked state. There is no need to dispose the components of the card removal device including the pickup roller, and the card cassettes 2 in the stacked state can be made as close as possible. In particular, in the case of the present embodiment, the partition plate 1 is provided between each card cassette 2.
7 can be brought close to the state where there are only 7, and the height of the cassette rack 15 can be kept low even when the number of card cassettes 2 to be handled is large, so that the entire card issuing apparatus can be downsized. it can.

Further, since one pickup roller 51 is used in common for taking out cards from all card cassettes 2, the number of parts is greatly reduced as compared with a case where pickup rollers are individually provided for each card cassette. Can be done.

Further, the card 1 taken out of the card cassette 2 is transported to the card issuing port 70 by the carrier device 34, so that the card 1 is located far from the card issuing port 70 (in the present embodiment, the lower cassette storage portion 18). (At a farther position) even when the card is taken out from the card cassette 2, the transport path through which the card 1 passes does not become long, and data stored in the card 1 may be lost. To be extremely reduced. Particularly, in the present embodiment, the carrier unit 33 holding the card 1 taken out of the card cassette 2 by the transport roller 53 moves to the card issuing port 70 to convey the card 1 to the card issuing port 70. The card 1 taken out of any card cassette 2
However, the transport path through which the card 1 itself passes (the pickup rollers 51 to the transport rollers 52 and 53) is common to all the cards 1 and is the shortest. Reliability is improved.

In the present embodiment, the cassette extracting device 40 and the card extracting device 50 integrated with the carrier unit 33 are provided.
5 and 54 and the solenoid 59 are the only carrier units 33
The pulse motors 12 and
Since 13 is attached to the base plate 14 side of the apparatus main body 10, the moving carrier unit 33 can be reduced in weight as much as possible even if it has an integrated structure. Therefore, the load on the carrier motor 11 for moving the carrier unit 33 is reduced. At the same time, since the lightened carrier unit 33 is moved without mounting a drive source other than the solenoid 59, the moving speed can be increased, and the card cassette 2 which is far from the card issuing port 70 and the card 1 can be moved.
Even when a document is taken out and issued, the time required for the issue can be reduced. Further, the pulse motors 12 and 13 are not mounted on the carrier unit 33, and the round shafts 31 and 3 for guiding the movement of the carrier unit 33 are provided.
2, the rotational driving force is transmitted mechanically, so wiring for supplying the motor driving energy to the carrier unit 33 is not required, and there is no fear of disconnection and the like, so that the operation reliability is improved. In addition, the cost can be reduced.

<Individual Description> Next, the configuration around the cassette rack 15 will be individually described in detail. First, the configuration around the cassette rack 15 will be described.
An opening / closing door (not shown) that closes the rear side of the cassette rack 15 (that is, the cassette insertion port 20 side) in the apparatus main body 10 is attached to be openable and closable. The door is normally closed so that only the person in charge can open and close the door, and an opening permission solenoid 81 that opens the door when a release signal is given from the host is attached to the base plate 14. Therefore, in the normal state in which the opening and closing door is closed, each cassette storage portion 18 of the cassette rack 15 is
The position on the rear end side of the card cassette 2 accommodated in the printer is restricted to some extent by the opening and closing door. On the other hand, the front of each cassette storage portion 18 remains open as a cassette outlet 19, and a shutter mechanism 82 is provided on the cassette outlet 19 side. As shown in FIGS. 2 to 4, the shutter mechanism 82 includes a shutter member 83 that is vertically displaceable immediately before the cassette outlet 19 and a shutter member 83 that is vertically displaced by a predetermined amount. A shutter opening solenoid 84 attached to the side plate 16b for displacement, and a shutter member 83 and the side plate 16b for urging the shutter member 83 to a predetermined position when the shutter opening solenoid 84 is not energized. It is constituted by a spring 87 locked between them. The shutter member 83 is a plate-shaped member having the same length as the cassette rack 15,
Shutter pieces 85 corresponding to the partition plates 17 and openings 86 corresponding to the cassette outlet 19 are formed alternately. Therefore, the shutter piece 85 is moved to the cassette outlet 19.
When the card cassette 2 is positioned at the position corresponding to the cassette opening 18, the forward movement of the card cassette 2 stored in the cassette storage section 18 is prohibited, and the opening 86
When the card cassette 2 is located at a position corresponding to the above, the card cassette 2 accommodated in the cassette accommodating portion 18 is in an open state in which the card cassette 2 can be moved forward. The shutter opening solenoid 84
Is normally in a non-energized state, the shutter piece 85 takes a forbidden position where the shutter piece 85 is positioned on the front surface of the cassette housing portion 18 under the urging force of a spring, and when the shutter opening solenoid 84 is energized, the shutter piece 85 moves the partition plate 17. The shutter member 83 is raised (or lowered) so as to coincide with the position, and the opening 86 is displaced so as to take an open position located on the front surface of the cassette housing portion 18 (see FIGS. 3 and 4).

Therefore, since the shutter piece 85 of the shutter member 83 is normally at the prohibition position located at the front of the cassette accommodating portion 18, when the card cassette 2 is inserted into each cassette accommodating portion 18 by opening the opening / closing door. Since the leading end abuts on the shutter piece 85, it does not drop from the cassette outlet 19, and the insertion amount is regulated, so that the insertion operation becomes easy. In addition, the cassette drawer 40 is actually
Prevents the card cassette 2 stored in the cassette storage unit 18 from being accidentally dropped from the cassette outlet 19 even when vibration is applied to the apparatus main body 10 when the card cassette 2 is not pulled out. Is done.
This also means that the storage position of the card cassette 2 is always regulated to a predetermined position, and the position of the concave portion 6 of each card cassette 2 in the stored state does not shift back and forth, and along the vertical common groove 23. The vertical movement of the pull-in pin 44 is not hindered. When the card cassette 2 is withdrawn by the cassette withdrawing device 40, the opening 86 is closed by the cassette housing portion 18.
The cassette can be pulled out without any trouble. In the present embodiment, the portion that does not require the cassette to be drawn is also commonly opened, but the shape of the shutter member 83 and the operation control thereof are simplified accordingly. That is, the present invention is not limited to the shutter member 83 of the present embodiment. For example, a bar-like member having a length that extends over the entire length of the cassette rack 15 and crossing all the cassette storage portions 18 is provided so as to be movable in the horizontal direction. You may.

B. Next, a configuration near the pickup roller 51 will be described.
Normally, a rubber roller is used as the pickup roller 51 in order to ensure the removal of the card 1 from the card cassette 2. However, if the material is deteriorated or foreign matter adheres to the surface, the removal ability of the card 1 is reduced. As it becomes unstable and may be fatal as a card issuing device,
Need replacement. In particular, in the present embodiment, since only one pickup roller 51 is used for taking out the cards 1 from all the card cassettes 2, the frequency of use thereof is so severe that the pickup roller 51 is easily deteriorated.
Exchange is mandatory. Generally, in this type of roller, a pickup roller is mounted on a shaft that passes between two frames (arms). Therefore, when replacing the roller, the frame must be removed using a tool, and the replacement operation is troublesome. It is. In this regard, in the present embodiment, the configuration is such that the pickup roller 51 can be replaced without using a tool, and the one-touch replacement is possible.

That is, as shown in FIGS. 15 and 16, one end of a shaft 91 rotatably supported on the arm 58 via a bearing 90 projects outward from the arm 58.
A pickup roller 51 is detachably fitted to one end of the protruding shaft 91. The pickup roller 5
An annular groove 94 is formed in a shaft hole 93 of one roll body 92, and a ring-shaped spring 95 is mounted on the groove 94. The inner diameter of the spring 95 is set smaller than the inner diameter of the shaft hole 93. Further, about half of the axial hole 93 in the axial direction is a round hole-shaped part 93a, and the other half is a flat deformed hole-shaped part 93b. The groove 94
Is formed in the round hole-shaped portion 93a. on the other hand,
The tip of the shaft 91 is formed with a taper 91a for facilitating insertion into the shaft hole 93 in which the spring 95 is incorporated, and is flattened so as to correspond to the deformed hole portion 93b. A modified shaft-shaped portion 91b is formed. Further, an annular concave portion 91c for positioning the spring 95 is formed in the shaft 91 at a position corresponding to the groove 94.

Thus, when the pickup roller 51 is replaced, when the roll body 92 is pushed into one end of the shaft 91, the built-in spring 95 is expanded along the taper 91a and the groove 94 and the groove 94 in the shaft hole 93 are expanded. The shaft 91 fits into the annular concave portion 91c and stops. At the same time, the deformed hole-shaped portion 93b of the roll body 92 fits into the deformed shaft-shaped portion 91b.
1b and the roll body 9 through fitting of the deformed hole-shaped portion 93b.
2 (accordingly, the pickup roller 51), and the pickup roller 51 surely rotates. At this time, since the axial force applied to the pickup roller 51 is small,
The roll body 92 does not move on the shaft 91. On the other hand, if a relatively large force is applied in the axial direction to remove the pickup roller 51, it cannot be regulated by the stopping force of the spring 95, and the pickup roller 51 can be removed from one end of the shaft 91 as it is.

That is, the pickup roller 51 of the present embodiment has a detachable fitting structure which is detachable by applying a predetermined force or more in the direction of the shaft 91, and transmits the rotation of the shaft 91 in the rotating direction. And has a roll body 92 attached to one end of a shaft 91.
Can be easily performed with one touch without using a tool.

The configuration in which the pickup roller 51 can be freely attached to one end of the shaft 91 by one-touch operation is not limited to the illustrated example, but may be a configuration having a detachable fitting structure using a magnet and a rotational force transmitting fitting structure, a pin. Or a structure having a detachable fitting structure and a rotational force transmitting fitting structure using a rotation stopper by the above.

C. Configuration Regarding Identification Selection of Target Card Cassette 2 A configuration relating to identification selection of the target card cassette 2 from among the plurality of card cassettes 2 stored in the cassette rack 15 in a stacked state will be described. For example, in a conventional card issuing device as shown in the above-mentioned Japanese Utility Model Application Laid-Open No. 5-92876, all the correspondence relations regarding card cassettes used for each card and mounting positions of the cassettes in the main body are previously determined. In order to prevent the card cassette from being mounted in a wrong place, the pair of cassette housing portions and card cassettes are formed with grooves that match each other.
Therefore, when the host issues an instruction to issue a certain card, the position of the card cassette in which the card is stored is known, and the corresponding pickup roller is driven to issue the target card. Becomes possible. However, in this method, the shape of the card cassette is different for each type of card, and the mounting position of each cassette is also specified, so that there is no freedom in selecting the mounting position of the cassette and lacks flexibility. This means that when the number of card cassettes to be handled becomes large, it is necessary to store the card cassettes while checking the mounting locations one by one, which is a troublesome and time-consuming operation.

On the other hand, in the present embodiment, even if the type of the card 1 is different, the card cassette 2 having the same shape common to all the cards 1 is used. The card cassette 2 and the cassette storage section 18 have a degree of freedom to be stored in any of the cassette storage sections 18 without a specific correspondence relationship of 1: 1. A different bar code 100 is assigned to each card cassette 2 in order to identify the type of card 1 in which cassette 1 is stored. This barcode 1
00 functions as an identification information section indicating type information of the card 1 stored in the card cassette 2. In the present embodiment, one of the peripheral surfaces traversed by the moving carrier unit 33 as shown in FIG. Cassette front end face 101
It is attached to. The direction of the bar of the bar code 100 is also set to be horizontal, and the reading operation of the bar code 100 is set to be performed by vertical scanning. A bar code scanner 102 as a reading means for reading such a bar code 100 is mounted on the carrier unit 33 in a direction facing the cassette outlet 19.

The operation of reading the barcode 100 of each card cassette 2 by the barcode scanner 102 is automatically executed at least when the power of the apparatus is turned on. That is,
The barcode scanner 102 sequentially reads the information of the barcode 100 for each of the card cassettes 2 stored in the cassette rack 15 for each of the cassette storage sections 18, so that the card cassette for which card 1 is stored in which cassette storage section 18. 2 is stored, and the information is sent to the host.
Store in AM. This processing is executed as a function of a positional relationship recognizing unit for recognizing a positional relationship between each cassette storage unit 18 and each card cassette 2. With this, the host can know which card cassette 2 for which card 1 is already stored in the cassette storage section 18 at which position when actually issuing the card. Can be.

In this case, when the power is turned on to perform the reading operation, it means not only the time when the power is actually turned on, but also the period from that time to when the card 1 is actually taken out. . The reason why the barcode 100 is read for all the card cassettes 2 at least when the power is turned on is that the CPU initializes all of the previous states at the time of turning on the power. Further, in the present embodiment, the reading operation of the barcode 100 by the barcode scanner 102 is restarted from the beginning not only when the power is turned on, but also when the door is opened and closed. This is because when the door is opened and closed, there is a possibility that the card cassette 2 has been replaced with respect to the cassette storage unit 18.

Accordingly, there is no problem even if the user freely changes the storage position of the card cassette 2. According to the present embodiment, scanning by the barcode scanner 102 is required to read the barcode 100 attached to each card cassette 2.
The scanner unit 3 whose scanning direction is set to the vertical direction and moves over the entire range of the cassette rack 15.
Since the movement can be performed by using the movement of No. 3, it can be easily realized without separately providing a scanning system.

The identification information portion of each card cassette 2 is not limited to the bar code 100, but may be irregularity information or the like. What is necessary is just to hold information readable. Further, the position where the barcode 100 or the like is attached is not limited to the cassette front end surface 101, but may be on a peripheral surface that the carrier unit 33 can traverse, for example, on the side surface of the cassette of the side plate 16a. What is necessary is just to change the mounting position of the code scanner 102.

D. Configuration for Removing Only One Card Next, a configuration for reliably removing only one card 1 from the card cassette 2 will be described with reference to FIGS.

In this type of card issuing apparatus, it is important that when a card issuance command is issued, only one corresponding card is issued without causing double feed or non-feed. By the way, in the conventional card issuing device, a limiter formed outside the card cassette and having a width of one card is provided on the transport path of the card, and two cards are overlapped by the width management of the limiter. Is regulated so that it is not issued. However, in this method, it is difficult to control the dimensions of the limiter width, and if the standard and type of the card used are different, the thickness of the card may be different. In the case where the degree of freedom is given, alignment with the limiter located outside the cassette cannot be achieved, and double feed or non-feed may occur.

In this respect, the present embodiment does not employ a configuration in which a limiter is provided outside the card cassette 2 and ensures only one card 1 by devising the relationship between the card cassette 2 itself and the pickup roller 51. It is configured so that it can be taken out. First, in the case body 3 for storing the plastic and strong cards 1 in a stacked state,
As shown in FIG. 17 and the like, a bottom plate 110 on which the card 1 is placed is provided. A leaf spring 112 is provided on the center of the bottom surface of the case body 3 via the bottom plate 110 in a state where an urging force acts so as to push the leading end side of the stacked cards 1 toward the ceiling surface 111 side. Installed. Further, on the bottom surface in the case body 3 and on both sides of the leaf spring 112, the rear end of the stacked cards 1 is pushed up toward the ceiling surface 111 via the bottom plate 110. A leaf spring 113 serving as a forward tilting means is attached in a state where the force acts. The push-up force of the leaf spring 113 is such that the uppermost rear end of the stacked cards 1 is pressed against the ceiling surface 111 in a state where the pickup roller 51 is in pressure contact with the cards 1 in the case body 3, and these cards 1 1 is set to be in a forwardly inclined state in which the pickup roller 51 side is relatively low (see FIG. 18). A rib 114 is formed on the inner wall surface of the case body 3 on the side of the card outlet 4, and the upper end of the rib 114 (accordingly, near the card outlet 4) is inclined toward the card outlet 4. Tapered portion 11
5 are formed. On the other hand, the pick-up roller 5 which enters the card cassette 2 through the roller entrance opening 5 at the pull-out position to take out the card 1
1 is a spring 6 which is larger than the pushing force of the leaf spring 112.
With the urging force of 0, the uppermost card 1 is pressed and contacted,
An entry amount restricting portion 116 that contacts a part of the case body 3 is formed on a part of the arm 58 as a support so that the amount of the pickup roller 51 entering the case body 3 is always constant. When the pick-up roller 51 of which the amount of entry is regulated is pressed and contacted, the top end position of the uppermost card in the stacked cards 1 that is inclined forward is higher than the position of the card outlet 4 by the tapered portion 115.
The height of the tapered portion 115 is set such that the position is shifted by the height of. The transport rollers 52
A card position sensor 117 for optically detecting the leading end of the card 1 taken out is provided at a position immediately after the card 1.

Here, μ ₁ ; coefficient of friction between pickup roller 51 and card 1 μ ₂ ; coefficient of friction between card 1 and ceiling surface 111 μ ₃ ; coefficient of friction between card 1 F ₁ ; pickup roller Card repetition output by rotation of 51 P ₁ ; Pressing force between pickup roller 51 and card 1 P ₂ ; Pressing force of card 1 against ceiling surface 111, μ ₁ ≫μ ₂ , μ ₃ , P ₁ > P ₂ Then, F ₁ = μ ₁ P ₁ −μ ₂ P ₂ −μ ₃ (P ₁ + P ₂ ).

Therefore, when the pickup roller 51 is brought into a state of being pressed against the card 1 in the card cassette 2 pulled out from the cassette storage section 18 while rotating, the uppermost position directly contacted by the pickup roller 51 is reached. The card repetition output F ₁ shown by the above formula acts on the card 1, and the uppermost card 1 advances while its tip side warps upward according to the tapered portion 115, and moves from the card outlet 4 to the case body 3. I go outside. At this time, the transport roller 52 is also rotating at the same speed as the pickup roller 51, and the leading end of the card 1 taken out enters the space between the transport rollers 52 and is taken out further forward. In this operation, when the leading end of the card 1 is detected by the card position sensor 117, the solenoid 59 is energized at that time and the pickup roller 51 is retracted so as to escape from the roller entrance opening 5, and Move away from card 1. Therefore, although the pickup roller 51 continues to rotate, the repetitive output does not act on the succeeding card 1 and double feed is prevented. On the other hand, the transport of the card 1 taken out this time is carried by the transport roller 52 and further by the transport roller 53.
, The card 1 is completely removed from the card cassette 2.

In such an operation of taking out the card 1,
The double feed prevention action of the tapered portion 115 will be described. If the coefficient of friction μ ₃ between the cards 1 is always constant, basically, even if the uppermost one card 1 is fed and conveyed, 2
No conveying force acts on the first and subsequent cards 1, but in reality, the friction coefficient between the first and second cards and the second and third cards 1 The coefficient of friction between the sheets may differ. Under such circumstances, when one card 1 the uppermost sent receiving Repetitive output F ₁ of the pickup roller 51, the second sheet below it, 3
The first card 1 is also fed, and the leading end of each card 1 stored in the forwardly inclined state abuts on the tapered portion 115. Since the card 1 is strong, the top card 1 receiving the repetitive output F ₁ directly by the pickup roller 51 has a repetitive output F ₁ that is sufficiently larger than the resistance generated by the tapered portion 115. The card 1 having a strong waist is sent to the card outlet 4 side while warping so as to ride on the tapered portion 115 (see FIG. 19B). On the other hand, the second and subsequent cards 1 have tapered portions 11.
5 does not receive a repetitive output enough to overcome the resistance force generated by 5 and cannot be warped in accordance with the tapered portion 115.
Double feed after the first sheet is prevented. From another perspective,
When the leading ends of several cards 1 are brought into contact with the tapered portion 115 at the time of removal, a gap is created between the cards 1, so that the cards 1 are easily peeled off, effectively preventing double feed, and at the same time, the tapered portion 115. According to the movement of the card 1 in the above, while the space between the first and second cards 1 changes to the dynamic friction state, the space between the second and third cards 1 changes to the static friction state and Only the first sheet is easy to move, 2
It is conceivable that double feed is prevented by making it difficult for the first sheet to move. In this way, paying attention to the card 1 having a strong stiffness unlike the paper used in the paper feeding device, the card 1 stacked in the forward inclined state is taken out while the tip side is warped by the tapered portion 115, so that the multifeed is performed. Can be reliably prevented.

On the other hand, if there is a variation in the amount of the pickup roller 51 entering the card cassette 2, the pickup roller 51 may enter the card 1
May cause non-feeding by merely abutting the leading end of the card against the rib 114, or the card 1 may easily come into contact with the ceiling surface 111 because the pickup roller 51 enters too shallow, causing slippage due to slippage. There is. In this regard, in the present embodiment, the pressing force of the spring 60 for the pickup roller 51 is set sufficiently higher than the lifting force of the leaf spring 112, and the entry amount restricting portion 116 of the arm 58 always contacts the ceiling surface 111. As a result, the amount of entry of the pickup roller 51 is regulated so as to be always constant, so that a stable repetitive output can always be exerted and non-feeding does not occur.

E. Regarding the Positioning of the Card Cassette 2 The card cassette 2 stored in the cassette storage section 18 of the cassette rack 15 can have a fixed position in a stored state and a pulled-out position pulled out for taking out a card. Positioning is performed so as not to cause displacement. For this purpose, as shown in FIG. 20, a cam body 120 integrated with the gear 46 is provided on the round shaft 31.
At a predetermined position of the cam body 120, two notches 120a,
120b are formed. The cam unit 1 is rotatably supported by a fulcrum 121 on the carrier unit 33.
Roller-shaped cam follower 12 constantly rolling on the peripheral surface of 20
2 is provided. The arm 123 is urged toward the cam body 120 by a spring 124. Further, a cassette origin sensor 1 which is turned on / off by using the distal end side of the arm 123 as an actuator 125
26 is also mounted on the carrier unit 33. The cassette origin sensor 126 is set to be turned on when the arm 123 is displaced in a state where the cam follower 122 enters either the cutouts 120a or 120b.

Incidentally, as shown in FIG.
A guide pin 127 shorter than the pull-in pin 44 is formed integrally with the draw-in pin 44 on the rear side, and two step-like slit holes 128a and 128b formed on the side surface of the carrier unit 33 are inserted into the recess. When the pin 44 and the guide pin 127 pass through, the slider 43 is slidable within a certain range.
The retaining pin 129 is inserted into the pull-in pin 44 and the guide pin 127.

In such a configuration, when the target card cassette 2 is located at the fixed position (the pull-in pin 44 is located at the left end of the slit hole 128a and the vertical common groove 2).
3 and engages with the concave portion 6 of the card cassette 2). As shown in FIG. 20A, the cam follower 122 enters the notch 120a for the fixed position with respect to the cam body 120, and the actuator 125 Turns on the cassette origin sensor 126. In this state, when the cassette conveying motor 12 is driven to rotate the round shaft 31, the gear 46 is rotated, so that the slider 43 slides rightward via the rack 42, so that the pull-in pin 44 and the recess 6 The card cassette 2 is pulled out through the engagement. At this time, since the cam body 120 also rotates at the same time, as shown in FIG.
The actuator 125 is also displaced in the direction away from it because it comes out of 20a, and the cassette origin sensor 126 is turned off. When the card cassette 2 is pulled out to a predetermined pulling position, the cam follower 122 is pulled out of the notch 120b for the pulling position.
As a result, the actuator 125 turns on the cassette origin sensor 126. The ON signal is used to control the cassette transport pulse motor 12, and the power supply to the cassette transport pulse motor 12 is cut off. The motor is de-energized and the gear 46 is in a rotatable and unstable state, but the cam follower 122
b and the cam body 120 (therefore, the gear 4
Since the rotation of 6) is restricted, the card cassette 2 in the pulled-out state does not inadvertently move in the front-rear direction, and is maintained at the predetermined drawing position.

F. Regarding Various Sensors In the card issuing device according to the present embodiment, the card position sensor 1 described above is used for timing control of various operations and the like.
17. In addition to the cassette origin sensor 126, various optical and mechanical sensors are provided. This will be described with reference to FIGS. 7 and 8 which are schematically shown. First, in the apparatus main body 10, as shown in FIG. 7, a door opening / closing sensor 130 for detecting the opening / closing of the opening / closing door is provided. Further, a shutter origin sensor 131 that detects whether or not the shutter member 83 is at the origin position that is a prohibited position is provided.
Further, a carrier origin sensor 132 for specifying a reference position for determining the amount of movement of the carrier unit 33 is provided on the upper side. On the other hand, on the carrier unit 33, as shown in FIG. 8, a card position sensor 133 disposed just before the transport roller 52 to detect the leading edge of the card 1 is disposed on the exit side of the transport roller 53 to detect the leading edge of the card 1. And a card exit sensor 134 for detecting the rear end. A detection hole 135 formed at a position vertically penetrating through a part of the front end of the case main body 3 of the card cassette 2.
A pair of upper and lower card presence / absence sensors 136 for detecting the presence / absence of the card 1 in the card cassette 2 in the pulled-out state is also mounted on the carrier unit 33 via (see FIG. 6).

G. Regarding operation timing control of each unit until card issuance As in the present embodiment, the carrier unit 33 moves to the position of the target card cassette 2 and
Is pulled out, one card 1 is taken out of the card cassette 2 drawn out, and the taken-out card 1 is conveyed by the carrier unit 33 to the card issuing port 70 to be issued. In this embodiment, the card issuance time is controlled by controlling the operation timing so that the operation of each unit is performed as simultaneously as possible. Is shortened. At this time, if the timing of the next operation is temporally controlled, the operation becomes uncertain. Therefore, in the present embodiment, a reliable trigger is prepared to ensure the operation reliability.

The flowchart shown in FIG. 22 and FIG.
Referring to a time chart shown in FIG. 3, when a card issuance command is issued during standby at the home position (lowest position), the processing operation of moving the carrier unit 33 to the position of the target card cassette 2 by driving the carrier motor 11. Is performed. During the movement of the carrier unit 33, the card cassette 2 from the cassette rack 15 is moved.
In order to complete the preparation for pulling out, the shutter release solenoid 84 is driven to open the shutter member 83 in parallel, and the solenoid 59 is driven to move the pickup roller 51 to the retreat position. The evacuation processing to be performed is performed in parallel. Thus, when the carrier unit 33 moves to the position of the target card cassette 2, the card cassette 2 is ready to be pulled out, and there is no time loss.

Subsequently, the cassette transport pulse motor 1
By driving the cassette 2, the cassette withdrawing device 40 performs the withdrawal process of the target card cassette 2. At this time, the completion of the movement of the carrier unit 33 is determined from the number of pulses accumulated in the position deviation counter of the carrier motor 11 and is used as a trigger for starting the driving of the cassette carrying pulse motor 12. After the target card cassette 2 is pulled out by the cassette pullout device 40, the solenoid 59 is de-energized, the pickup roller 51 is displaced to a card retrievable position, and the card 1
Take-out operation. At this time, judgment is made based on two signals: a movement completion signal from the command pulse state of the cassette transport pulse motor 12 and a detection signal from the cassette origin sensor 126 for detecting that the card cassette 2 is at the regular draw-in position. , Which triggers the start of card removal (return of the pickup roller 51). During the card removal operation by the card removal device 50, while the taken-out card 1 is being conveyed by the conveyance roller 52, the solenoid 59 is energized to perform a retreating process for retreating the pickup roller 51 to the retreat position. The transport pulse motor 12 is driven to rotate in the reverse direction to perform the cassette return process of returning the card cassette 2 that has been pulled out to the original position in the cassette storage unit 18. At this time, a trigger for retracting the pickup roller 51 using a detection signal of the card position sensor 133 for detecting a position before the first card 1 passes the pickup roller 51 is used.

Next, a carrying operation is carried out to carry out the drawn card 1 to the card issuing port 70 by the carrier unit 33. When the carrier unit 33 is moved to the card issuing port 70 in this manner, the movement completion signal of the cassette conveying pulse motor 12 and the detection signal from the cassette origin sensor 126 for detecting that the card cassette 2 is at the original fixed position are obtained. By using the two signals as triggers, safety when moving the carrier unit 33 is ensured.
That is, the carrier unit 33 does not start the movement operation in a state where the card cassette 2 protrudes. During this transport operation, the solenoid 59 is de-energized again, and the pickup roller 51 is displaced to the card readable position to perform a standby process, and the shutter release solenoid 84 is also de-energized to move the shutter member 83 to the prohibited position. A return process for displacement is performed.

In the present embodiment, the cassette origin sensor 126 is configured as a sensor for detecting two states when the card cassette 2 is at the fixed position and the drawn-out position. Thus, it is determined whether the card cassette 2 is located at the fixed position or the drawn-out position.

H. Regarding an origin detection method for moving the carrier unit 33 In order to move the carrier unit 33 to the drawing position of each card cassette 2, a reference position sensor for determining an absolute position (reference point) with respect to the movement of the carrier unit 33 is provided. Carrier origin sensor 132 is required. However, the detection point of the carrier origin sensor 132 may be different for each product due to a sensor mounting error, a variation in sensor characteristics, and the like. In this case, the physical position of the carrier origin sensor 132 may be adjusted for each product, but it is troublesome and not always accurate. Even if the physical position of the carrier origin sensor 13 is adjusted, it is not possible to adjust the variation in the interval between the card cassettes. In this regard, the present embodiment incorporates an adjustment program for automatically correcting the carrier origin sensor 132 in a process before shipping without performing the physical position adjustment.
Schematically, the length from the carrier origin sensor 132 to each cassette pull-out position is measured, and those measured values are stored in an EEPROM (Electric Erasable Programmable Programmable Memory) of the host.
The data is stored in the ROM, and when the user actually uses the data after shipment, the data stored in the EEPROM is used to control the movement of the carrier unit 33 so as to perform the positioning. Control processing according to the adjustment program for this will be described with reference to the flowchart shown in FIG.

First, at the stage before shipment, the carrier unit 33 is manually moved to the position of the card cassette 2 farthest (the lowest = tenth) from the carrier origin sensor 132, and the draw-in pin 44 is moved to the corresponding cassette storage section. 18
The adjustment program is run in a state where the adjustment program is positioned in the draw-out groove 22. This adjustment operation is performed in an empty state without storing the card cassette 2 in the cassette rack 15. The adjustment program is started by appropriately setting the dip switches and turning on the power switch.

First, the carrier motor 11 is turned on by exciting it on the spot, but the gain is initially set low. Thereafter, when the carrier unit 33 is moved up and down by a fixed amount of pulses, the carrier unit 33 can move up and down only by a gap in which the draw-in pin 44 can move in the drawing groove 22. By sampling the actual vertical movement at this time by the number of feedback pulses of the encoder directly connected to the carrier motor 11,
Data for positioning the drawing pin 44 in the vertical direction (stacking direction) center of the drawing groove 22 can be obtained. Therefore, the moving amount of the carrier motor 11 is adjusted so that the pull-in pin 44 is positioned at the center of the pull-out groove 22.
Is held at the moved position. Subsequently, the gain of the carrier motor 11 is returned to normal, and the retracting pin 44 is also allowed to move in the vertical direction.
When the detection operation of the carrier origin sensor 132 is performed by returning to and returning from the position, the number of pulses between the carrier origin sensor 132 and the center position of the lowermost drawer groove 22 for the card cassette 2 is accurately recognized. it can. Then, the same sampling operation is performed for the second card cassette 2 from the lowest, and so on. For the remaining card cassettes 2, the same operation is repeated. Can be accurately grasped with respect to all the movement amounts of the drawing groove 22 with respect to the center position. The data measured by running the adjustment program in this way is transferred to the EEPR on the host side.
By writing the data in the OM, in actual use after shipment, only the position of the carrier origin sensor 132 is detected, and thereafter, the carrier origin sensor 132 and each card cassette 2 (drawing groove for the card cassette 2) stored in the EEPROM are used. 22
By using the distance (movement amount) data between (the center positions), the movement amount to the target card cassette 2 to which the issuance command was issued can be acquired and the movement can be performed accurately.

If the distance between the card cassettes 2 (the distance between the draw-out grooves 22) in the cassette rack 15 can be accurately determined in assembling, the above-mentioned operation does not need to be performed for all card cassette positions. At a minimum, only the card cassette position furthest from the carrier origin sensor 132 may be actually measured and stored, and the remaining card cassette positions may be arithmetically calculated by an operation using the measured value.

I. Regarding Operation Control of Carrier Unit 33 at Power-On In the present embodiment, carrier unit 33 is moved to the position of target card cassette 2, target card cassette 2 is pulled out from cassette rack 15, and card 1 is removed from card cassette 2. Since the card 1 is taken out and further transported to the card issuance opening 70 by the carrier unit 33, the card issuance operation cannot be performed unless the transport path in the vertical direction of the carrier unit 33 is secured. This causes an error such as breakage of the card cassette 2 or the carrier unit 33 itself. In particular, when the power is turned on or when the power is restored, it is a rise from a state that is not electrically managed, and various situations can occur. Therefore, before turning on the carrier motor 11, the situation is grasped by information obtained from various sensors. If the carrier unit 33 is not movable, the carrier motor 11 (and thus the movement of the carrier unit 33) is controlled so as to start the normal operation after eliminating the obstacle factor.

As a phenomenon that the carrier unit 33 cannot be moved, it is conceivable that the power is turned off during a card issuing operation due to a power failure or other reasons. In this case, since the card cassette 2 is in a state of being pulled out from the cassette rack 15 and the drawing pin 44 is located in the drawing groove 22, the carrier unit 33 is moved to the position of the carrier origin sensor 132 in this state. The detection operation cannot be performed. In consideration of such a phenomenon, in the present embodiment, a program relating to the operation control of the carrier unit 33 as shown in FIG. 25 is incorporated.

This operation control is started when the power is turned on (including when the power is restored after a power failure). First, the detection state of various sensors such as the cassette origin sensor 126 is checked, and whether the carrier unit 33 is movable is determined based on the state. If movement is possible, carrier motor 1
1 is turned on to move the carrier unit 33 upward, the detection operation of the carrier origin sensor 132 is performed, and then the carrier motor 11 is rotated in reverse to lower the carrier unit 33 at a low speed, and all the card cassettes 2 The barcode 100 is read by scanning with the code scanner 102. All the card cassettes 2 read from the barcode 10 by this scanning operation
By writing the card type information related to the cassette storage unit position information and moving the carrier unit 33 to the home position (for example, the lowest position).
The card issuance standby state.

On the other hand, when the power is turned on, the carrier unit 3
If it is determined that the movement of No. 3 is impossible, operation control for securing the carrier unit transport path is executed. First, as a situation where movement is impossible, it is checked whether or not the retracting pin 44 is located at the home position (the position of the vertical common groove 23). If the draw-in pin 44 is not located at the home position, it is determined that the card cassette 2 is in the draw-out state and the draw-in pin 44 is located in the draw-out groove 22. In this case, the carrier motor 11 is turned on while the gain is low, and the carrier motor 11 is excited on the spot. Thereafter, when the carrier unit 33 is moved up and down by a fixed amount of pulses, the carrier unit 33 is
Can move up and down only by the width of the groove. By sampling the movement amount at this time as an actual measurement value, data for positioning the drawing pin 44 at the center of the drawing groove 22 can be obtained. Therefore, the gain of the carrier motor 11 is returned to normal, and excitation is performed in a state where the pull-in pin 44 is located at the center of the pull-out groove 22. By holding in this state, the draw-in pin 44 is located at the center of the draw-out groove 22, and
2, the pull-in pin 44 can be moved smoothly. In this state, by driving the cassette conveying pulse motor 12 to move the drawing pin 44 to the home position, the card cassette 2 that has been in the drawn state can be returned to the home position. The return of the card cassette 2 to the home position is detected by the cassette origin sensor 126. As a result, the carrier unit 33 can freely move in the up and down direction. Therefore, the normal operation (the detection operation of the carrier origin sensor 132, the card issuing port 70, etc.), and enters a card issuing standby state. In the operation for securing such a transport path, a shutter member 8 for holding the card cassette 2 at a fixed position in the cassette rack 15 is provided.
3 remains open, and the other card cassette 2 on which the carrier unit 33 is not positioned projects toward the cassette outlet 19 due to vibration or the like.
There is also the possibility of inhibiting the movement of 3. So, just in case,
The shutter member 83 is also operated to open and close.
If the shutter member 83 cannot be closed, it is determined that the card cassette 2 protruding toward the cassette outlet 19 is present, and an error is displayed to prompt the operator to repair.

The opening / closing operation of the shutter member 83 is performed similarly even when the card cassette 2 does not protrude at the position of the carrier unit 33.

J. Others In the present embodiment, the plurality of card cassettes 2 are vertically stacked by the cassette rack 15 and the card issuance operation is performed by moving the carrier unit 33 and the like in the up and down direction. The card issuing operation may be performed by stacking the cassettes in the horizontal direction and moving the carrier unit or the like in the horizontal direction.

According to the first aspect of the present invention, a single pickup roller common to all card cassettes is mounted on a carrier unit movable over the entire range of stacked card cassettes, and The card is moved to the position of the cassette, the card cassette is pulled out by the cassette drawer, the card can be taken out by the pickup roller of the card take-out device, and the taken-out card is conveyed to the card issuing port by moving the carrier unit. A new card issuance method requires a reference position sensor to determine the reference point for moving the carrier unit to the position of the target card cassette, and this reference position sensor is subject to sensor mounting errors and variations in sensor characteristics. The detection point may be different for each product, Moving the carrier unit to the desired position the card cassette remains becomes a hindrance when trying to perform the drawer, before shipment of the product,
The carrier unit is moved in the stacking direction of the card cassette to measure the length from the reference position sensor to the card cassette withdrawal position. The measured value is stored in the memory as the movement amount of the carrier unit, and the actual use after shipment is performed. Sometimes, when the carrier unit is moved to the position of the target card cassette, it is controlled so as to move from the position of the reference position sensor by the amount of movement based on the information stored in the memory. The position of the reference point for moving the carrier unit can be corrected substantially according to the state specific to the apparatus without adjusting the position of the apparatus. A cassette pull-out operation can be performed.

According to the second aspect of the present invention, in the operation control method of the card issuing device according to the first aspect, the draw-out groove formed in the cassette rack is provided with a claw for facilitating the movement of the claw body in the cassette drawer. There is a slight gap in the cassette stacking direction with respect to the body, but at the time of length measurement before shipping, the position where the claw body is the center position of the draw-out groove is set to the actually measured value in consideration of the gap in this draw-out groove. Therefore, when the carrier unit is moved to the draw-out position of the target card cassette at the time of actual use after the shipment and the card cassette is pulled out, the claw body rubs against one side of the draw-out groove, so that a deviation occurs. Therefore, the target card cassette can be smoothly moved along the center position of the drawer groove, and the target card cassette can be smoothly drawn out.

According to the third aspect of the present invention, in the operation control method of the card issuing device according to the first or second aspect, the reference position sensor is disposed at one end in the card cassette stacking direction, and the reference position sensor is located at a reference point before shipment. The length of the card cassette to the drawing position is measured only for the drawing position of the card cassette farthest from the reference position sensor, and the amount of movement from the reference point to the drawing position of another card cassette is calculated by calculation based on the measured value. Therefore, if the accuracy of the distance between the draw-out positions of the card cassettes can be obtained after assembling the cassette rack, only the length measurement from the reference point to the draw-out position of the farthest card cassette is performed, and the other card cassettes are measured. By calculating the amount of movement to the pull-out position based on the actual measurement value, the amount of movement of the scanner unit can be accurately controlled, It is also possible to simplify the load before working.
