When the use of the device is finished, among the data stored in the readout memory 29, the variable value data stored in the variable part 8b of the magnetic card 7 is sent to the arithmetic circuit 30, and calculations are performed according to the degree of use of the device. , this itching result is stored in the write memory 31.

Also, at almost the same time, an end signal E is sent to the motor drive circuit 26, and the motor 23 is driven to rotate in reverse.

By this motor drive, the magnetic card 7 is conveyed to the insertion slot 11 side, and along with this movement, the clock generation circuit 2
4, a clock pulse is sent to the interrupt memory 31 and the flip-flop 32.

Therefore, the new data stored in the read memory 31 is sequentially outputted in synchronization with the clock pulse, and is stored in the variable section 8b of the magnetic card 7 by the write drive circuit 33.

The magnetic card 7 in which the data in the variable portion 8b has been changed in this manner is conveyed to the insertion slot 11 and returned.

<Other Embodiments of the Present Invention> In the above embodiments, the optical stripes of the magnetic card were formed at equal intervals, but if the magnetic data and the optical stripes were formed at synchronized positions, the optical The stripes do not have to be evenly spaced.

Further, in the above embodiment, the optical sensor and the magnetic head were placed facing each other in order to reproduce the optical stripe and magnetic information provided on both sides of the magnetic card, but this The optical stripe and the magnetic information may be provided in parallel, and the optical sensor and the magnetic head may be arranged in the same direction, or the optical stripe may be provided on the side surface of the magnetic card.

Furthermore, in the above embodiment, a card processing device that rewrites data on a magnetic card has been described, but this applies to a card processing device that accepts cards that do not rewrite data, such as bank cash cards and credit cards. can be similarly applied.
