Abstract

PURPOSE:To prevent a magnetic card from being disabled to use in another device by providing a write auxiliary processing means which stores write completed data transiently and performs re-write based on storage data when a write error occurs. CONSTITUTION:A control circuit 50 reads data via a read head 36 when the magnetic card is inserted, and supplies it to the write auxiliary processing means 22, and stores it in a data storage processing circuit 65. When payment is performed, a processor 100 subtracts a sale amount from read data, and supplies a difference to a write head 32. After write is completed, the data is read again from the card, and is compared with the data after substraction, and the means 22 is started up when noncoincidence is obtained. The means 22 resets temporarily stored data when the write is performed normally, however, when an error occurs, read data is supplied to the head 32 as it is, and is written on the card. Therefore, the data in the card can be recovered to the one before reading. In such a way, since the data can be recovered to the one before reading even when the write error occurs in the magnetic card, it is possible to prevent the card from being disabled to use hereafter.

13) Write the subtracted data to the magnetic card 9 by applying the write magnetic head 36 via the write driver 47 (
Step 214), the control unit W50 repeats steps 213 to 215 until the writing is completed (step 215), when the writing is completed, the control unit W50
50 stops the step motor 45 (step 2
16). Furthermore, it is determined whether the data written on the magnetic card 9 is correct. That is, the control device 50 reversely rotates the step motor 45 in order to place the magnetic card 9 in the predetermined position of the card insertion slot 10 (step 217).
), when the magnetic card 9 is located at a predetermined position (step 218), the step motor 45 is stopped (step 219), and then the control device 50 rotates the step motor 45 in the forward direction (step 220). The data on the magnetic card 9 is taken into the controller f50 via the read magnetic nozzle 32 (step 22). This machine is executed until all the data has been read (steps 220 to 222). When all the data has been read, the controller 50 stops the step motor 45 (step 223), and The subtracted data is compared with the data just read (step 224). Here, if both are the same, the control device! If it is determined in step 150 (step 225), a reset command is issued (step 226), the step motor 45 is rotated in the reverse direction (step 227), and stopped when the magnetic card 9 reaches the point where it protrudes from the card slot 10. (Step 227
~229). At this time, the write auxiliary processing means 22
As shown in the figure, it is in a state of waiting for a command (step 302).
), When the command is received, the IIJrIj unit 70 determines the content of the command (step 303). When the control unit 70 determines that the command is a reset command, the lid unit 70 resets the storage unit 71 (step 304). Finish the process. On the other hand, if the control device 5o determines that the two do not match (step 225), the control device 50 controls the magnetic card 9
The step motor 45 is rotated in the reverse direction until it is at the predetermined position of the 10 card slots (steps 230 to 231).
Then, the control device 50 stops the step motor 45 (Step 232), determines that a write error has occurred, and issues a write command to the write auxiliary processing means 22 (Step 233). The step motor 45 is rotated in the forward direction until the write auxiliary processing means 22 completes writing of the original data (steps 234 to 235). At this time, the write auxiliary processing means 22 is in a state of waiting for a command as shown in FIG. 7 (step 302), and the control section 70
When a command arrives, it determines the content of the command (step 303
). If the control unit 70 determines that the command is a write command due to a write error, it retrieves the original data from the storage unit 71 (step 305) and provides this to the write magnetic head 36 via the write driver 67 (step 306). ,
This operation continues until all data has been written (steps 305-30?). After the writing is completed, the control unit 70 resets the storage unit 71 (step 304), and ends the process. When the writing is completed in this way, the control device 50 stops the step motor 45 (step 236), turns on the unusable indicator light 13, and stops the subsequent operation.
