Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a magnetic card read / write device according to an embodiment of the present invention, and FIG. 2 is a side view of the same. In FIG. 1, a magnetic card read / write device mainly includes a CPU 1 that issues an instruction to operate the entire card reader, an EPROM 2 that contains an operation program for the card reader, read data when a magnetic card is read, and printing when printing. A RAM 3 for storing data, a card position detection sensor 4, a motor drive unit 5, a magnetic card R / W unit 6, a print head drive unit 7, and a rewritable EEPROM 8 are added.

In FIG. 2, this magnetic card read / write device is provided with a roller 11 for carrying a magnetic card along a carrying path 15 for the magnetic card 10, and further provided with a thermal head 12 and a magnetic head 13. In addition, the card position detection sensor 4 is provided at an appropriate place. Reference numeral 9 is a motor for driving the roller 11, and 14 is a magnetic card insertion slot.

By the way, what is usually called ROM is called EPROM2, which is used for writing.
2 electrically write data to and erase EPROM
(2) Ultraviolet rays were applied to the transparent glass portion provided on the upper portion to erase it. Therefore, at the time of rewriting data, it is necessary to remove the EPROM 2, apply ultraviolet rays to erase everything, and write again. The RAM 3 is one that can electrically rewrite data easily.
However, while the data is not erased even when the voltage is not applied, the RAM 3 has a drawback that the data is erased when the voltage is not applied.

In contrast to the above electronic parts, the EEPROM 8 has the characteristics of the above-mentioned two electronic parts, and the data can be easily rewritten electrically, and the data is not erased even when the voltage is not applied. It is an electronic component that has. Next, the procedure for recording the number of processes in the EEPROM 8 will be described while explaining the operation of the magnetic card read / write device. The order of processing is insertion of the magnetic card 10, read, write, verify (write check), printing, and ejection of the magnetic card 10.

(1) Card insertion: In the magnetic card read / write device, the magnetic card 1 is detected by the card position detection sensor 4.
It is detected that 0 has been inserted into the insertion slot 14 of the magnetic card 10, and the CPU 1 is notified. The CPU 1 commands the motor drive unit 5 to rotate in the direction of sucking the magnetic card 10. When the motor 9 rotates and the magnetic card 10 is taken into the magnetic card read / write device and then the magnetic card 10 is conveyed to a predetermined position, the card position detection sensor 4 detects it and informs the CPU 1. CPU 1 is a motor drive unit 5
Command to stop spinning. The motor 9 stops rotating and the magnetic card insertion operation ends.

(2) Read: The card position detection sensor 4 detects the position of the magnetic card 10 and informs the CPU 1 of the position.
The CPU 1 determines whether or not the magnetic card 10 is at the read start position. If the magnetic card 10 is not present at the read start position, the motor drive unit turns the motor 9 in the direction in which the magnetic card 10 moves to the read start position. Command 5 The magnetic card 10 is conveyed to the read start position by the rotation of the motor 9. When the card position detection sensor 4 detects that the magnetic card 10 is at the read start position, CP
U1 is notified, and the magnetic card read / write device starts the read operation. The CPU 1 issues a read command to the magnetic card R / W unit 6 and a motor drive unit 5 to rotate the magnetic card R / W unit 6. All the data entered in the magnetic read is put in the RAM 3, and the CPU 1 analyzes and reads the data in the RAM 3. When the card position detection sensor 4 detects that the magnetic card 10 has been conveyed to a position away from the magnetic head 13, it notifies the CPU 1, issues a read end command to the magnetic card R / W unit 6, and stops the rotation of the motor drive unit 5. Issue an order. Then, the motor stops and the read operation ends. After the read operation is finished, the value of the read count of the EEPROM 8 is incremented by one. If the read result is abnormal, the value of the read error count is incremented by 1.

(3) Write: The data to be written is expanded on the RAM 3 by the CPU 1. The position of the magnetic card 10 is detected by the card position detection sensor 4, and C
Tell PU1. The CPU 1 determines whether or not the magnetic card 10 is at the write start position. If the magnetic card 10 is not present at the write start position, the motor drive unit turns the motor 9 in the direction in which the magnetic card 10 moves to the write start position. Command 5 When the card position detection sensor 4 detects that the magnetic card 10 is at the write start position, CP
U1 is notified, and the magnetic card read / write device starts the write operation. The CPU 1 issues a write command to the magnetic card R / W unit 6 and a motor drive unit 5 to rotate it. When the card position detection sensor 4 detects that the magnetic card 10 has been conveyed to a position away from the magnetic head 13, it notifies the CPU 1, issues a write end command to the magnetic card R / W unit 6, and stops the rotation of the motor drive unit 5. Issue an order.
Next, the motor 9 stops and the write operation ends. After the write operation is finished, the value of the number of writes of the EEPROM 8 is incremented by 1.

(4) Verify: The operation is almost the same as the read, and the CPU 1 compares the read data and the write data after the read is completed. After the verify operation is completed, E
The value of the read count of the EPROM 8 is incremented by 1. If the result of verification is different from the data at the time of writing, the value of the number of write errors is increased by one.

(5) Printing: The position of the magnetic card 10 is detected by the card position detection sensor 4, and the result is sent to the CPU 1. C
The PU 1 determines whether or not the magnetic card 10 is at the print start position. If the magnetic card 10 is not present at the print start position, the motor drive unit turns the motor 9 in the direction in which the magnetic card 10 moves to the print start position. Command 5 When the card position detection sensor 4 detects that the magnetic card 10 is at the print start position and notifies the CPU 1, the magnetic card read / write device starts the printing operation. First, the CPU
1 commands the motor drive unit 5 to convey the magnetic card 10 to the desired position for printing, and to move the print head to the magnetic card 1.
Drop to 0. Next, the CPU 1 issues a print command to the print head drive unit 7, and issues a command to the motor drive unit 5 to convey the magnetic card 10 at the printing speed. RAM3
When the print data corresponding to the print data set in (1) is printed, the thermal head 12 is pulled up from the magnetic card 10 and the motor drive unit 5 is instructed to stop the rotation of the motor 9 to end the printing operation. After the printing operation is completed, the value of the number of printing times of the EEPROM 8 is incremented by one.

(6) Card ejection: The CPU 1 commands the motor drive unit 5 to rotate in the direction of ejecting the magnetic card 10. The motor 9 rotates and conveys the magnetic card 10 from the inside of the magnetic card read / write device to a position waiting for the magnetic card to be removed. When the card position detection sensor 4 detects that the magnetic card has been conveyed to the waiting position, the CPU 1 is notified. The CPU 1 commands the motor drive unit 5 to stop the rotation. The motor 9 stops rotating and waits for the magnetic card 10 to be removed. When the magnetic card 10 is removed, the card ejection operation is completed.

By carrying out as described above, the number of processes of the magnetic card read / write device is set to the EEPROM 8 for each process.
Since the data is recorded in, it is possible to easily know the number of processing times of the magnetic card reader / writer device even after removing it from the system.
