Move to the position shown in 41a'41b ',
Make sure that each brush contacts the contacts 13a, 13b. When the IC card error code 122 is set to 1, which indicates an error of the IC card, for example, the brushes 41a and 41b are prevented from coming into contact with the contacts 13a and 13b.

FIG. 1 is a flow chart for explaining the operation of one embodiment of the present invention. Next, the operation of the embodiment of the present invention will be described in detail with reference to FIGS.

The customer inserts the IC card 11 into the card reader / writer 4. In response to the IC card 11 being inserted into the card reader / writer 4, the CPU 2 reads data from the magnetic stripe 12 and stores the read data in the RAM 9. Then, CPU12
Determines whether the IC card is out of order based on the IC card error code 122 of the data read from the magnetic stripe 12. Here, if the IC card error code 122 is set to 1, for example, the IC
When the IC card error code is 0, for example, the brush included in the card reader / writer 4 continues.
Touch the contact 13 of the IC card 11 to
Read the IC card information from the read IC card information in RAM9
Store at.

If there is any abnormality in the operation of reading data from the memory 17 of the IC card 11 in the above operation, the CPU 2 of the automatic teller machine 1
Determines that an abnormality has occurred in the IC card 11. Then, the CPU 2 sets the IC card error bit stored in the RAM 9 to 1, and subsequently turns on the motor of the card reader / writer to drive the IC card 11 against a head (not shown) to cause the magnetic stripe 12 to move. The error bit data updated to, for example, 1 is written. If there is an error in writing the error bit data, the error bit data may be rewritten or error processing may be performed. Then, when the writing is normally performed, the card is returned and the operation ends.

On the other hand, if the IC card information is read normally, the transaction processing is performed, and after the transaction processing is completed, the card is returned and the operation is completed. This transaction processing operation is not related to the present invention, so its explanation is omitted.

As described above, in this embodiment, the IC is connected without performing the connecting operation to the contact of the IC card and the power supplying operation.
By reading the magnetic stripe of the card, it is determined non-electrically whether or not there is any abnormality in the IC card, so it is possible to quickly detect the presence or absence of a failure and the electrical configuration of the card reader / writer side. Be protected.

In the above-described embodiment, when the IC card has an abnormality, the brush of the card reader / writer is prevented from coming into contact with the contact of the card, but the present invention is not limited to this. It is also possible to provide a switch on the power supply so that power is not supplied by controlling this switch.

Furthermore, although the contact type IC card has been described in the above embodiment, a contactless data card, that is, from the viewpoint of controlling careless power supply to a storage medium that supplies power in a contactless manner. It can be applied similarly.

[Effects of the Invention] As described above, according to the present invention, when it is non-electrically detected that the data indicating that the storage medium has a failure is recorded, the power supply means outputs the data. Since the electric power is controlled not to be supplied to the storage medium, the reliability of the storage medium processing device is improved.
