Entire Structure

[0030] FIG. 1 is an outward perspective view showing a card issuing device to which the present invention is applied. FIG. 2 is a cross-sectional view showing the card issuing device which is cut at the “A-A” position in FIG. 1. FIG. 3 is a plan view showing the card issuing device which is viewed from the “Z2” direction side. In FIG. 3, a code reader and a frame which supports the code reader are detached from the card issuing device. Further, in FIG. 3, a card issuing device does not store cards.

[0031] A card issuing device 1 (card conveyance unit) shown in FIG. 1 is communicably connected with a host apparatus not shown and used. The card issuing device 1 issues a card 2 as a member card whose front face is indicated (printed) with a bar code 2a (one dimensional code) and two dimensional code 2b based on a card issue instruction from the host apparatus. The two dimensional code 2b is, for example, a “QR” code (registered trademark).

[0032] As shown in FIGS. 1 and 2, the card issuing device 1 includes a card storage part 3 which stores cards 2 having not issued yet. Further, the card issuing device 1 includes a card conveyance mechanism 4 on the “X1” direction side with respect to the card storage part 3. The card storage part 3 and the card conveyance mechanism 4 are installed on a base 20 in a rectangular plate shape.

[0033] As shown in FIG. 1, the card storage part 3 includes a cassette holder 5 and a plurality of card cassettes 6 which are detachably attached to the cassette holder 5. A plurality of the card cassettes 6 is arranged in the “Y” direction. In this embodiment, the card storage part 3 includes six card cassettes 6(1) through 6(6). Six card cassettes 6(1) through 6(6) are arranged so that three rows each of which is comprised of two cassettes disposed in the “X” direction are arranged in the “Y” direction. Cards 2 are laminated and stored in each card cassette 6 in a posture that each face of a card 2 printed with a bar code 2a and two dimensional code 2b is directed to the “Z2” direction side.

[0034] Further, as shown in FIG. 2, the card storage part 3 includes a card send-out mechanism 7 structured to send out a card 2 one by one to the “X1” direction side from each of the card cassettes 6(1) through 6(6). In addition, the card storage part 3 includes card collection parts 8 which are respectively provided on the “Z1” direction side with respect to the card cassettes 6(1), 6(3) and 6(5) in the card cassettes 6 disposed in two rows in the “X” direction.

[0035] As shown in FIG. 3, the card conveyance mechanism 4 includes a carriage 10, a carriage conveyance passage 11 which is extended in the “Y” direction (arrangement direction of a plurality of the card cassettes 6) on the “X1” direction side with respect to the card storage part 3, and a carriage moving mechanism 12 structured to move the carriage 10 along the carriage conveyance passage 11. The carriage 10 includes a conveying mechanism 13 which is capable of conveying a card 2 in the “X” direction. The conveying mechanism 13 takes a card 2 which is sent out from the card cassette 6 and holds the card 2 in the carriage 10, and the conveying mechanism 13 sends out the card 2 from the carriage 10 to the “X1” direction side or to the “X2” direction side.

[0036] The carriage conveyance passage 11 is set with a plurality of taking-in positions “E” where a card 2 sent out from each of the card cassettes 6 is taken into the carriage 10 on one side in the “X” direction with respect to the respective card cassettes 6. Further, the carriage conveyance passage 11 is set with a reading position “R” where a bar code 2a on a card 2 held by the carriage 10 is read, a sending-out position “P” where a card 2 is sent out from the carriage 10 to one side in the “X” direction, and a collecting position “Q” where a card 2 is collected from the carriage 10. In this embodiment, the taking-in position “E” is set on the “X1” direction side with respect to each row comprising two card cassettes 6. Therefore, the taking-in position “E” is provided at three positions on the carriage conveyance passage 11. The reading position “R” and the sending-out position “P” are set at the same position as each other. In this embodiment, the reading position “R” and the sending-out position “P” are set in an end portion on the “Y2” direction side of the carriage conveyance passage 11. Further, the collecting position “Q” is set at the same position as the taking-in position “E”. Therefore, the collecting position “Q” is set at three positions on the carriage conveyance passage 11 similarly to the taking-in position “E”.

[0037] In this embodiment, as shown in FIG. 1, a code reader 14 is installed on the “Z2” direction side with respect to the reading position “R”. The code reader 14 is fixed to a frame 21 which is attached to an end portion on the “Y2” direction side of the carriage moving mechanism 12. The frame 21 is provided with a first extended part 21a which is extended from the carriage moving mechanism 12 to the “Z2” direction side, a bent part 21b which is bent to the “Y1” direction side from an end on the “Z2” direction side of the first extended part 21a and is extended to the “Y1” direction side, and a second extended part 21c which is extended to the “Z1” direction side from an end on the “Y1” direction side of the bent part 21b. The code reader 14 is attached to the bent part 21b in a posture facing the “Z1” direction side.

[0038] The code reader 14 faces a card 2 on the carriage 10 in the “Z” direction at the reading position “R”. The code reader 14 includes, for example, an image sensor and irradiates an illumination light toward a card 2 to acquire images of a bar code 2a and two-dimensional code 2b and then, image analysis is performed to acquire information of the codes. When the code reader 14 reads information from a card 2, the read information is transmitted to a host apparatus.

[0039] Further, a control part 15 is attached to the base 20 at a position overlapping with an end portion on the “Y1” direction side of the carriage conveyance passage 11. As shown in FIG. 2, the control part 15 includes a board 16 on which a circuit provided with a CPU, ROM, RAM and the like is mounted.

[0040] The control part 15 drives and controls the card send-out mechanism 7, the carriage moving mechanism 12, the conveying mechanism 13 and the code reader 14.

[0041] Further, after the control part 15 has driven the code reader 14, the control part 15 acquires a result whether the information that the code reader 14 has read has been transmitted to a host apparatus or not. More specifically, in a case that the information that the code reader 14 has read is transmitted to the host apparatus during a predetermined time period after the control part 15 drives the code reader 14, it is determined that a reading operation of the bar code 2a and the two-dimensional code 2b has been normally performed. Further, in a case that the information that the code reader 14 has read is not transmitted to the host apparatus during a predetermined time period after the control part 15 drives the code reader 14, it is determined that a reading operation of the bar code 2a and the two-dimensional code 2b has not been normally performed. In other words, the control part 15 acquires a result whether a reading operation of the code reader 14 has been normally performed or not by monitoring presence or absence of the transmission of information from the code reader 14.

Card Issuing Operation

[0042] FIG. 4 is a flow chart showing a card issuing operation for issuing a card 2. When a card 2 is to be issued, a card issue instruction is transmitted from a host apparatus to the card issuing device 1. The card issue instruction is inputted into the control part 15. The card issue instruction includes designating information which designates one of the card cassettes 6 from which a card 2 having not issued yet is supplied.

[0043] As shown in FIG. 4, when a card issue instruction is inputted, the control part 15 drives the carriage moving mechanism 12 to arrange the carriage 10 to the taking-in position “E” located on the “X1” direction side with respect to the designated card cassette 6 (step “ST1”). Next, the control part 15 drives and controls the card send-out mechanism 7 to send out a card 2 from the designated card cassette 6 to the taking-in position “E”. Simultaneously, the control part 15 drives and controls the conveying mechanism 13 of the carriage 10 to take the card 2 into the carriage 10 (step “ST2”).

[0044] After that, the control part 15 drives and controls the carriage moving mechanism 12 to move the carriage 10 to the reading position “R” and then, the control part 15 drives and controls the code reader 14 to perform a reading operation in which a code (bar code 2a and two-dimensional code 2b) is read from the card 2 on the carriage 10 (step “ST3”).

[0045] In this embodiment, in a case that information read by the code reader 14 is transmitted to the host apparatus, the control part 15 determines that reading of information from the card 2 has been normally performed (step “ST4”: “Yes”). As a result, the control part 15 drives and controls the carriage moving mechanism 12 to arrange the carriage 10 at the sending-out position “P” and, after that, the control part 15 drives and controls the conveying mechanism 13 to send out the card 2 to the “X1” direction side from the carriage 10 (step “ST5”). In this manner, issue of a card 2 has been completed. In this embodiment, the reading position “R” and the sending-out position “P” are the same as each other. Therefore, when the reading operation is performed, the carriage 10 is arranged at the sending-out position “P”. Accordingly, in this embodiment, the control part 15 does not drive the carriage moving mechanism 12 after the reading operation is performed, and the control part 15 drives the conveying mechanism 13 to send out the card 2 from the carriage 10 to the “X1” direction side.

[0046] On the other hand, in a case that information read by the code reader 14 is not transmitted to the host apparatus, and that the control part 15 determines that reading of information from a card 2 has not been performed normally (step “ST4”: “No”), the control part 15 drives and controls the conveying mechanism 13 to move the card 2 in the “X” direction on the carriage 10. A moving direction and a moving amount of the card 2 which is moved on the carriage 10 by the control part 15 are previously set. After that, the control part 15 drives and controls the code reader 14 again to perform a re-reading operation (step “ST6”).

[0047] In a case that reading of information from the card 2 has been normally performed by the re-reading operation (step “ST7”: “Yes”), the control part 15 drives and controls the carriage moving mechanism 12 to arrange the carriage 10 at the sending-out position “P” and, after that, the control part 15 drives and controls the conveying mechanism 13 to send out the card 2 to the “X1” direction side from the carriage 10. In this embodiment, the reading position “R” and the sending-out position “P” are the same as each other. Therefore, when the reading operation is performed, the carriage 10 is arranged at the sending-out position “P”. Accordingly, the control part 15 does not drive the carriage moving mechanism 12 after the reading operation has been performed, and the control part 15 drives the conveying mechanism 13 to send out the card 2 from the carriage 10 to the “X1” direction side (step “ST8”). As a result, issue of a card 2 has been completed.

[0048] In this embodiment, in a case that information read by the code reader 14 is not also transmitted to the host apparatus by the re-reading operation, and that the control part 15 determines that reading of information from the card 2 has not been normally performed (step “ST7”: “No”), the control part 15 drives and controls the carriage moving mechanism 12 to arrange the carriage 10 at the collecting position “Q” and, after that, the control part 15 drives and controls the conveying mechanism 13 to send out the card 2 to the “X2” direction side from carriage 10 (step “ST9”). As a result, the card 2 is sent out from the carriage 10 toward the “X2” direction side and the card 2 is guided by the guide member 9 to be collected in the card collection part 8. In this embodiment, in a case that the card 2 is to be collected in the card collection part 8 located on the “Z1” direction side with respect to the card cassette 6(5), the reading position “R” and the collecting position “Q” are the same as each other. Therefore, when the reading operation has been performed, the carriage 10 is arranged at the collecting position “Q”. Accordingly, in this embodiment, the control part 15 does not drive the carriage moving mechanism 12 after the reading operation has been performed, and the control part 15 drives the conveying mechanism 13 to send out the card 2 to the “X2” direction side from the carriage 10.

[0049] According to the card issuing device 1 in this embodiment, when a card 2 is to be issued as a member card or the like, a code (bar code 2a and two-dimensional code 2b) indicated (printed) on a surface of the card 2 is read and the read information is transmitted to the host apparatus. Therefore, in the host apparatus, the information of the code printed on the card 2 to be issued can be associated with information of a member who is an owner of the card 2.

Details of Card Storage Part

[0050] Next, details of the card storage part 3 will be described below with reference to FIGS. 1 through 3. As shown in FIGS. 1 through 3, the card cassette 6 is formed in a rectangular tube shape having a bottom and is, as a whole, formed in a rectangular parallelepiped shape. As shown in FIG. 2, an end portion on the “Z1” direction side of each card cassette 6 is provided with an opening part 6a facing the “X1” direction side when the card cassette 6 is attached to the cassette holder 5.

Further, the card send-out mechanism 7 includes, in the card storage part 3, a second card send-out mechanism 7B structured to send out a card 2 stored in the card cassette 6(2), 6(4) or 6(6) located on the “X2” direction side of two card cassettes 6 arranged in the “X” direction to the “X1” direction side.

[0052] The first card send-out mechanism 7A is provided in each end portion on the “Z1” direction side of the card cassettes 6(1), 6(3) and 6(5). The first card send-out mechanism 7A includes a slit 22 (see FIG. 3) which is provided in a bottom face of the card cassette 6 so as to be extended in the “X” direction, and a card sending-out claw 23 (see FIG. 2) which is capable of protruding in the slit 22. The card sending-out claw 23 is capable of engaging with an edge of a card 2 located at the lowest position of cards 2 stored in the card cassette 6 from the “X2” direction side. Further, the first card send-out mechanism 7A includes, as shown in FIG. 2, a chain drive mechanism 24 for moving the card sending-out claw 23 in the “X” direction, and a motor 25 for driving the chain drive mechanism 24. The card sending-out claw 23 of the first card send-out mechanism 7A is fixed to a chain of the chain drive mechanism 24.

[0053] When a card 2 is to be sent out to the “X1” side from the card cassettes 6(1), 6(3) and 6(5), the control part 15 drives the first card send-out mechanism 7A. In other words, the control part 15 drives the motor 25 to operate the chain drive mechanism 24, and the card sending-out claw 23 is protruded in the slit 22 and moved to the “X1” direction side. As a result, the card sending-out claw 23 is engaged with a card 2 located at the lowest position of the cards 2 laminated in the card cassette 6 to send out the card 2 to the taking-in position “E” of the carriage conveyance passage 11.

[0054] The second card send-out mechanism 7B includes, similarly to the first card send-out mechanism 7A, a slit 22 which is provided in a bottom face of the card cassette 6 and is extended in the “X” direction and a card sending-out claw 23 which is capable of being arranged in the slit 22. Further, the second card send-out mechanism 7B includes a belt mechanism 26 which is provided in each of end portions on the “Z1” direction side of the card cassettes 6(2), 6(4) and 6(6), a plurality of sending-out rollers 27 provided on the “Z1” direction side with respect to the card cassettes 6(1), 6(3) and 6(5), and a motor 28 for driving the belt mechanism 26 and a plurality of the sending-out rollers 27. A plurality of the sending-out rollers 27 is disposed in the “Y” direction with respect to the chain drive mechanism 24 of the first card send-out mechanism 7A.

[0055] When a card 2 is to be sent out to the “X1” side from the card cassettes 6(2), 6(4) and 6(6), the control part 15 drives the second card send-out mechanism 7B. In other words, the control part 15 drives the motor 28 to operate the belt mechanism 26 so that the card sending-out claw 23 is protruded in the slit 22 and is moved to the “X1” direction side. Further, the control part 15 rotates the sending- out rollers 27. As a result, the card sending-out claw 23 is engaged with a card 2 located at the lowest position of cards 2 which are laminated in the card cassette 6, and the card 2 is moved to the “X1” direction side and is transferred to the sending- out rollers 27. The sending-out rollers 27 further convey the transferred card 2 to the “X1” direction side and send out to the taking-in position “E” of the carriage conveyance passage 11. In this embodiment, when a card 2 is to be sent out to the “X1” side from the card cassettes 6(2), 6(4) and 6(6), the card sending-out claw 23 of the first card send-out mechanism 7A has been moved to the “Z1” direction side of the chain drive mechanism 24.

[0056] In this embodiment, the card collection part 8 is provided on the “Z1” direction side with respect to the card cassettes 6(1), 6(3) and 6(5) which are located on the “X1” side in the card storage part 3. A guide member 9 is disposed between the card collection part 8 and the card cassette 6. The guide member 9 is a plate spring which is inclined to the “Z2” direction side as going toward the “X1” direction side. A card 2 sent out to the “X1” direction side from each card cassette 6 by the card send-out mechanism 7 is guided by the guide member 9 to the carriage 10 which is arranged at the taking-in position “E”. On the other hand, a card 2 to be returned to the “X2” direction side from the carriage 10 located at the collecting position “Q” is guided to the “Z1” direction side by the guide member 9 and is stored in the card collection part 8.

As shown in FIG. 6, the side plate part 56 is provided with a recessed part 56a which is recessed to the “Y2” direction side in a center portion in the “X” direction. Further, as shown in FIG. 7, the side plate part 56 is provided with a second guide groove 56b which is recessed to the “Y2” direction side at a position facing the first guide groove 53a. In addition, the second frame 52 is, as shown in FIGS. 6 and 10, provided with a motor holding part 58 which is protruded from the side plate part 56 to the “Y1” direction side on the “Z1” direction side with respect to the second guide groove 56b. The motor 60 is held by the motor holding part 58 and is located on the “Z1” direction side with respect to the first guide groove 55a and the second guide groove 56b.

[0063] As shown in FIG. 7, a pressing mechanism 67 which presses the driven roller 62 toward the drive roller 61 is disposed between the first frame 51 and the second frame 52. The pressing mechanism 67 includes a pressing spring support member 68 extended in the “Y” direction on the “Z1” direction side with respect to the second rotation shaft 62a, and pressing springs 69 which are disposed in a compressed state between the second rotation shaft 62a and the pressing spring support member 68 on both sides in the “Y” direction with respect to the driven roller 62. An end part on the “Y2” side of the pressing spring support member 68 is fixed to the second frame 52, and an end part on the “Y1” direction side of the pressing spring support member 68 is fixed to the first frame 51.

[0064] As shown in FIG. 8, the gear train 73 includes a first gear 64 engaged with a pinion 60a which is provided in an output shaft of the motor 60, a first gear train 65 comprised of a plurality of gears disposed on the “X2” direction with respect to the first gear 64, and a second gear train 66 comprised of a plurality of gears disposed on the “X1” side with respect to the first gear 64. The first gear train 65 and the second gear train 66 are symmetrically structured in the “X” direction with a rotation center of the first gear 64 as a reference. The first gear train 65 transmits rotation of the motor 60 to the first rotation shaft 61a of the drive roller 61 of the first roller pair 71 which is rotatably supported at an end part on the “X2” direction side of the first frame 51. The second gear train 66 transmits rotation of the motor 60 to the first rotation shaft 61a of the drive roller 61 of the second roller pair 72 which is rotatably supported at an end part on the “Xl” direction side of the first frame 51. Therefore, the drive rollers 61 and the driven rollers 62 of the roller pairs 71 and 72 are rotated in a synchronous manner.

[0065] In this embodiment, ss shown in FIGS. 5, 9 and 10, the carriage 10 includes a card detection part 80. The card detection part 80 includes a sensor board 81 fixed to the second frame 52 from the “Y1” side and photo sensors 82 which are disposed on the sensor board 81. The carriage frame 50 includes a second cover 59 made of resin which covers the sensor board 81 from the “Y2” direction side. The second cover 59 is fixed to the second frame 52 together with the sensor board 81.

[0066] The photo sensors 82 are disposed one by one at both ends in the “X” direction of the sensor board 81. The card detection part 80 detects a card 2 based on a signal of the photo sensor 82 located at an end on the “X2” direction side when the card 2 is taken into the carriage 10. Further, the card detection part 80 detects a card 2 based on a signal of the photo sensor 82 located at an end on the “X1” direction side when the card 2 is sent out from the carriage 10. The sensor board 81 is provided with a sensor circuit which determines a passage of a card 2 based on a signal from the photo sensor 82. An output from the card detection part 80 (sensor circuit) is inputted into the control part 15.

Operation of Conveying Mechanism

[0067] When a card 2 sent out by the card send-out mechanism 7 toward a taking-in position “E” of the carriage conveyance passage 11 is to be taken into the carriage 10, both ends in the “Y” direction of the card 2 is guided by the first guide groove 53a and the second guide groove 56b. As a result, a center portion in the “Y” direction of the card 2 is capable of being held by the drive roller 61 and the driven roller 62 of the first roller pair 71. In this embodiment, the control part 15 drives the motor 60 of the conveying mechanism 13 to drive the respective drive rollers 61 of the roller pairs 71 and 72. As a result, the card 2 is taken into the carriage 10 in a state that the card 2 is sandwiched between the drive roller 61 and the driven roller 62 of the first roller pair 71 in the “Z” direction. After that, the card 2 is conveyed to the “X1” direction side by the first roller pair 71 and is stopped in a state that both end portions in the “X” direction of the card 2 are sandwiched by the first roller pair 71 and the second roller pair 72. As a result, the card 2 is held by the carriage 10.

[0068] Next, in a case that the control part 15 determines that a reading operation by the code reader 14 has been normally performed, the control part 15 drives the motor 60 to rotate the drive rollers 61 of the respective roller pairs 71 and 72 in a normal direction, and the card 2 is sent out from the carriage 10 to the “X1” direction side.

[0069] On the other hand, in a case that the control part 15 determines that the reading operation by the code reader 14 has not been normally performed, the control part 15 drives the motor 60 to rotate the drive rollers 61 of the respective roller pairs 71 and 72 in a normal direction or a reverse direction, and the card 2 is moved on the carriage 10 only by a predetermined amount to a predetermined side in the “X” direction. After that, the control part 15 drives the code reader 14 to perform a re-reading operation.

[0070] In this embodiment, in a case that the re-reading operation has not been normally performed, the control part 15 drives the motor 60 in a reverse direction to rotate the drive rollers 61 of the respective roller pairs 71 and 72 in a reverse direction, and the card 2 is sent out from the carriage 10 to the “X2” direction side.

Operations and Effects

[0071] In the card conveyance unit in this embodiment, the code reader 14 faces a card 2 which is held by the carriage 10 in the “Z” direction at the reading position “R” set in the carriage conveyance passage 11 and a code (bar code 2a and two-dimensional code 2b) is read. Therefore, the card cassette 6, the carriage conveyance passage 11 and the code reader 14 are avoided being arranged in this order in the “X” direction perpendicular to an arrangement direction of a plurality of the card cassettes 6. Accordingly, the card conveyance unit is prevented or restrained from being enlarged in the “X” direction. Further, in a structure that the card cassette 6, the carriage conveyance passage 11 and the code reader 14 are arranged in this order in the “X” direction, another send-out mechanism is required for further sending out a card 2 on which a reading operation has been performed by the code reader 14 to the “X1” direction side. However, when the reading position “R” by the code reader 14 is provided on the carriage conveyance passage 11, the card 2 having finished a reading operation by the code reader 14 can be sent out to the “X1” direction side by the conveying mechanism 13 provided in the carriage 10.

[0072] In this embodiment, the control part 15 acquires a result whether the code reader 14 has read a code in a reading operation or not and, in a case that the code has not been read, the control part 15 drives and controls the conveying mechanism 13 to move the card 2 on the carriage 10 in the “X” direction and perform a reading operation again. In other words, in a case that the code reader 14 is unable to read a code in the reading operation, a card 2 taken into the carriage 10 may be set in a state that the card 2 is not located at an appropriate position on the carriage 10. In this embodiment, the conveying mechanism 13 is capable of moving the card 2 in the “X” direction on the carriage 10. Therefore, in a case that the code reader 14 is unable to read a code, when the conveying mechanism 13 is driven and controlled to move the card 2 on the carriage 10, the code may be read by the code reader 14.

[0073] In this embodiment, the reading position “R” and the sending-out position “P” are the same as each other. Therefore, after the reading operation is finished, the card 2 can be sent out to the “X1” direction side without moving the carriage 10.

[0074] In this embodiment, one taking-in position “E” among a plurality of the taking-in positions “E”, the reading position “R” and the sending-out position “P” are the same as each other. Therefore, when a card 2 is to be sent out from the card cassette 6(5) and the card cassette 6(6) located on the other side in the “X” direction with respect to the taking-in position “E”, which is set at the same position as the reading position “R” and the sending-out position “P”, reading of a code and sending-out to the “X1” direction side of the card 2 can be performed without moving the carriage 10 from the taking-in position “E”.

[0075] In this embodiment, the collecting position “Q” where a card 2 is collected from the carriage 10 is set in the carriage conveyance passage 11. The control part 15 acquires a result whether the code reader 14 has read a code in a reading operation or not and, when the code has not been read, the control part 15 drives and controls the carriage moving mechanism 12 to arrange the carriage 10 at the collecting position “Q” and drives and controls the conveying mechanism 13 to send out the card 2 to the other side in the “X” direction from the carriage 10. Therefore, a card 2 which is unable to read a code by the code reader 14 can be ejected to the other side in the “X” direction from the carriage 10 and collected.

Other Embodiments

[0076] The reading position “R” and the sending-out position “P” can be set at an arbitrary position on the carriage conveyance passage 11. Further, the reading position “R” and the sending-out position “P” may be different from each other.

[0077] Further, in the embodiment described above, the card collection part 8 is provided on the “Z1” direction side of the card cassettes 6(1), 6(3) and 6(5). However, the card collection part 8 may be provided at only one position. In this case, the collecting position “Q” is set at one position located on the “X1” direction side with respect to the card collection part 8.

[0078] In accordance with an embodiment of the present invention, a front face of a card 2 may be printed with only one of a bar code 2a and two-dimensional code 2b. In a case that only a bar code 2a is printed on a card 2, a bar code reader may be adopted as the code reader 14 which irradiates reading light to the card 2 to read information based on the reflected light.

[0079] In accordance with an embodiment of the present invention, in a case that, as a card 2 on which a code is provided, a magnetic card having an information recording part such as a magnetic stripe is to be issued, or an IC card having an IC chip is to be issued, the card issuing device 1 in this embodiment is used as a card conveyance unit in which a card 2 is conveyed from the card storage part 3 to the “X1” direction side. Further, a card processing device for performing reading and writing of magnetic information to a magnetic stripe and reading and writing of information to an IC chip is installed on the “X1” direction side with respect to the sending-out position “P” of the card issuing device 1 and thereby, a card issuing device is structured. In this case, the card processing device takes a card 2 which is sent out from the carriage 10 to the “X1” direction side and performs reading and writing processing of information on the card and then, the card is issued.
