Next, the basic flow of the basic processing operation and the outline of the card transport operation of the card processing apparatus 1 of the present embodiment will be briefly described with reference to the flowchart of FIG.
When the rewrite card 2 is inserted into the card insertion section 4 (step 1 (indicated by S1 in the figure, the same shall apply hereinafter)), the optical sensor 11A as card insertion detection means detects the rewrite card 2 and the detection signal Is input to the control unit 30, and the conveyance roller drive motor 16 is driven by a command from the control unit 30 to start conveyance of the rewrite card 2 and convey it to the data processing unit 13 along the conveyance path 5 (step 2). . When a card detection signal is input from the optical sensor 11B to the control unit 30, the data processing unit 13 operates in response to a command from the control unit 30 to execute data reading and writing processes (steps 3 and 4). Thereafter, the rewrite card is conveyed to the color change processing unit 20 (step 5). When a card detection signal is input from the optical sensor 21A to the control unit 30, the conveyance roller drive motor 25 is driven by an instruction from the control unit 30, and the rewrite card 2 is conveyed to the position of the optical sensor 21B. Here, when the rewrite card 2 passes through the optical sensor 11C and the detection output from the optical sensor 11C disappears, the conveyance roller drive motor 16 on the data processing unit 10 side is stopped. When a card detection signal is input to the control unit 30 from the optical sensor 21B, the rewrite card 2 is stopped in the cooling chamber 23 and cooled, and the display unit 2A is discolored to erase visual data (step 6). When the color changing process is completed, the transport roller drive motor 25 is reversed to transport the rewrite card 2 to the print processing unit 14 of the data processing unit 10 (step 7). Here, when the detection output from the optical sensor 11C is input to the control unit 30, the conveyance roller drive motor 16 is driven, and when the detection output of the optical sensor 21A is lost, the conveyance roller drive motor 25 on the color change processing unit 20 side is stopped. . When the rewrite card 2 is conveyed to the print processing section 14, the thermal head 14A heats the display section 2A to discolor the print portion, thereby printing visual data corresponding to the written data on the display section 2A (step 8). . When the printing process is completed, the rewrite card 2 is ejected from the card insertion unit 4 (step 9).

Next, the detailed processing operation of the card processing apparatus 1 of this embodiment will be described with reference to the flowchart of FIG.
In step 11, it is determined whether or not the optical sensor 11 </ b> A has detected the rewrite card 2. If the determination is YES, the transport roller drive motor 16 is driven to transport the rewrite card 2, and the process proceeds to Step 12.
In step 12, it is determined based on the output of the card insertion direction detection sensor 12 whether or not the insertion direction is correct. If the determination is yes, go to step 13.

In step 13, the card data is read by the data processing unit 13.
In step 14, it is determined whether or not the card can be processed based on the read data. If the determination is yes, go to step 15.
In step 15, card data is written.
In step 16, it is determined whether or not the writing is correctly performed. If the determination is YES, the process proceeds to step 17.

  In step 17, it is determined whether or not the card is a newly issued card based on the read data. If it is an issued card in which the visual data is already printed on the display unit 2A, the determination is NO, and the process proceeds to step 18 in order to erase the visual data by the color change process, and the rewrite card 2 is conveyed to the color change processing unit 20. If it is a newly issued card in which visual data is not printed on the display unit 2A, the determination is YES, and the process skips steps 18 to 20 and proceeds to step 21.

In step 19, it is determined whether or not the optical sensor 21B has detected the rewrite card 2. If detected, the process proceeds to step 20.
In step 20, it is determined whether or not the rewrite card 2 is held in a predetermined cooling time stop in the cooling chamber 22 that is cooled to a temperature t1 or less. It is determined that the entire surface of the part 2A has changed to the first color and the visual data has been erased, and the process proceeds to step 21.

In step 21, the rewrite card 2 is conveyed to the print processing unit 14 of the data processing unit 13.
In step 22, the print processing unit 14 heats the print portion of the display unit 2A to the temperature t2 or higher by the thermal head 14A and prints visual data.
In step 23, the rewrite card 2 is ejected from the card insertion section 4.

  According to the card processing device 1 having the configuration of the first embodiment, since the visual data of the display unit 2A of the rewrite card 2 can be rewritten by simple cooling processing and heating processing, it is not necessary to perform complicated temperature control. Visual data update processing can be performed very simply.

Next, a second embodiment of the card processing apparatus of the present invention having an automatic rewrite card issuing function will be described.

It is a top view and a side view. In addition, the same code | symbol is attached | subjected to the same element as 1st Embodiment, and description is abbreviate | omitted.

In the figure, a card processing device 40 according to the second embodiment is provided with a card hopper unit 41 for storing the rewrite card 2 to be issued and an operation unit 42 for performing an issue operation of the rewrite card 2. Other configurations are the same as those of the first embodiment.
As shown in FIGS. 7 and 8, the card hopper unit 41 is disposed on the back side in the card transport direction of the color change processing unit 20 and stores the rewrite card 2. The stored rewritable card 2 is sent out to the transport path 5 by a sending roller (not shown) that contacts the bottom surface of the lowermost card.
In this embodiment, the card hopper unit 41 stores and issues the collected rewritten rewrite cards together with the unissued new rewrite cards in a state where the visual data is printed.

The card issuing operation of this embodiment will be described with reference to the flowchart of FIG.
In step 31, it is determined whether or not a card issuance command is issued from the operation unit 42 to the control unit 30, and if the determination is YES, the process proceeds to step 32.
In step 32, the delivery roller is driven to deliver the rewrite card 2 from the card hopper unit 41 and conveyed to the insertion direction detection sensor 12 of the data processing unit 10.
Thereafter, the operation is the same as steps 12 to 23 of the first embodiment.

  That is, if it is determined in step 33 that the card insertion direction is correct, the card data is read in step 34, and if it is determined that the card can be processed in step 35, the card data is written in step 36. If it is determined in step 37 that writing has been performed correctly, it is determined in step 38 whether or not the card is an unissued new card. If it is determined that the card is an issued recycled card whose visual data is printed on the display unit 2A, In step 39, the color is transferred to the color change processing unit, and the visual data of the display unit 2A is erased by the color change processing in steps 40 and 41. On the other hand, if it is determined in step 38 that the card has not been issued, the process proceeds to step 42 without being conveyed to the color change processing unit 20. In step 42, the rewrite card 2 is conveyed to the print processing unit 14. In step 43, visual data is printed on the display unit 2A by the thermal head 14A, and in step 44, the rewrite card 2 is issued from the card insertion unit 4.

  According to the card processing device 40 having the configuration of the second embodiment, the rewrite card 2 can be reissued without being erased, that is, without erasing the visual data on the display unit 2A.

However, the issued card sent from the card hopper unit 41 is Since it passes through the color change processing unit 20 and is transported to the data processing unit 10, the color change processing unit 20 executes a visual data erasure process on all cards issued regardless of whether it is a new card or a recycled card. May be. In this case, immediately after step 32 in FIG. 9, the operations of steps 39 to 41 are executed and the process proceeds to step 33. However, the determination in step 40 uses the detection output of the optical sensor 21A instead of the optical sensor 21B. Further, the determination operation of step 38 is not necessary, and when the determination is YES in step 37, the operation proceeds to step 42.

Next, a third embodiment of the present invention will be described.
In the third embodiment, the visual data of the collected recycled card is erased and then stored in the card hopper unit 41 to be issued. The hardware configuration is the same as that of the second embodiment, only the software is different. FIG. 10 shows the card issuing operation of this embodiment.

In FIG. 10, the operations from Step 51 to Step 55 are the same as Steps 31 to 37 of the second embodiment, and thus description thereof is omitted here.
In the present embodiment, after the determination in step 57 becomes YES, the image data is not conveyed to the color change processing unit 20, but is immediately conveyed to the print processing unit 14 in step 58, and visual data is printed in step 59. In step 60, the card is ejected and issued.
In addition, what is necessary is just to cool the visual data of the recycling card before storing in the card hopper part 41 to the temperature t1 or less outside.

Next, a fourth embodiment of the present invention will be described.
In the present embodiment, a cancellation processing function is provided.

When the rewrite card 2 to be canceled is inserted into the card insertion unit 4, the operation is started. Since operations in steps 71 to 74 are the same as those in steps 11 to 14 in the first embodiment, the description thereof is omitted here.

In step 75, the data processor 13 erases the card data.
In step 76, it is determined whether or not the erasure is correctly performed. If the determination is YES, the process proceeds to step 77.
In steps 77 to 79, the same color change processing operation as that in steps 18 to 20 of the first embodiment is executed to erase the visual data on the display unit 2A.
In step 80, for example, the cancellation card is collected by controlling the conveyance system so as to convey the collection card to the card collection stock unit.
On the other hand, if it is determined NO in any of steps 72, 74, and 76, the process proceeds to step 81, where the card is ejected from the card insertion unit 4 and returned.

According to this configuration, the visual data erasure process of the display unit 2A is automatically performed simultaneously with the cancellation card collection process. Therefore, when the collected rewrite card 2 is recycled, the visual data erasure process is separately performed. There is no need.
The visual data erasing process in steps 77 to 79 of the fourth embodiment may be omitted and the visual data may be collected without being erased, and the cancellation function of such a configuration is desirably incorporated into the apparatus of the second embodiment. .

In this case, moisture in the cooling chamber may be periodically removed, or the humidity in the cooling chamber may be monitored and controlled by monitoring the humidity.
Moreover, in the said embodiment, although it was set as the structure which detects the carrying-in to the color-change process unit 20 by providing the optical sensor 21B, you may abbreviate | omit the optical sensor 21B. In this case, when the rewrite card 2 passes through the optical sensor 21A and the detection signal from the optical sensor 21A disappears, it may be determined that the rewrite card is carried into the color change processing unit 20.
Further, the card conveyance form is not limited to roller conveyance, but may be belt conveyance or the like.
Further, in the above embodiment, the card transport system drive source (drive motor) is provided separately for the data processing unit, the color change processing unit, and the feed roller, but if one drive source is shared, The card processing device can be reduced in size and cost.
