This is a computer system that integrates an M 151, a RAM 152, an input/output device 153, and an interface 154. The determining means 11 controls the CPU of the determining means II when the IC card 4 is inserted into the socket 5 electrically connected to the interface 154.
150 and the performance function-PU of the IC card 4 communicate, and only when certain conditions are met, the IC card 4
A part or all of the processing program in the storage section FROM is determined by the arithmetic function gate PI of the judgment means 11 (7) RAM
15H: Transferred, and the CPU 150 combines a part of the processing program with the processing program inside the ROM 151, and the CPU 150! St! When the processing program has been created as a working program, or when the entire processing program has been loaded into the RAM 152 and created as an internal processing program for driving the CPU 150, the prepayment amount and other necessary information are stored in the magnetic recording medium of the magnetic card. Writing means 1
2 can be given. The determination means 11 which has become operable in this manner reads the code Cd recorded in the second magnetic recording area 9 of the magnetic card 2 inputted from the reading means 10 and the code stored in the internal ROM 151. It is configured to compare the received code Cm and, when a match is detected, issue an issuance command and output necessary data such as the amount of money.

It is possible to write into the first magnetic recording area 8 of the magnetic card 2 via the magnetic card 2.

The operation of the embodiment configured in this way will be explained.

FIG. 10 is a flowchart shown to explain the operation of this embodiment.

First, the magnetic card issuing device 6 is operated. When the successive control means 6 starts its operation, the determination means 11 determines that I
It is determined whether the IC card 4 is installed in the socket 5 (step 500), and if the IC card 4 is not installed (step 500), the determination means 11:
Since the program on the IC card 4 cannot be read, a display (not shown) indicates that the IC card 4 is not inserted (step 50), and the operation ends.

On the other hand, when the IC card 4 is inserted into the socket 5, the determining means 11 communicates with the IC card 4 and confirms the protocol and parameters (step 501). Next, the confirmation of the protocol and the normal meter is completed, and the determining means 11 determines whether the predetermined conditions are met between the determining means 11 and the IC card 4 (step 503). This determination is also performed by the IC card 4. Here, if the determining means 11 determines that the predetermined conditions are not met (step 503
), a message indicating that the conditions are not satisfied is displayed on a display (not shown), and the process is terminated. This conditional judgment is I
If the conditions do not match, the IC card 4 will not output the processing program to the outside.

Further, if the predetermined conditions are met, the determining means 1
1 (step 503), the decision hand 1u
ll issues a command to output the processing program to the IC card 4, reads the program from the IC card 4, and stores it in the RAM.
152 (step 5051).

Of course, since the IC card 4 side also determines that the predetermined conditions are met, the processing program is output in accordance with the instructions from the determining means 11.

Then, the determining means 11 determines whether all the processing programs have been read based on the control J signal from the IC card 4 (step 506), and if the reading is not completed, steps 505 and 506 are further repeated.

Then, when the reading is completed, the determining means 11 processes the program so that it becomes an internal processing program (C step 507). This is a process in which the processing program read from the IC card 4 is combined with the internal processing program when it is a part of the entire processing program.
This is a process that enables operation when the processing program read in is the full processing program. Next, determination means 1
Step 508 is to determine whether the above processing is completed.
), if not completed, the process of steps 507 to 508 is repeated, but if completed, a display (not shown) indicates permission to issue a magnetic card (step 509).

When the magnetic card issuance permission display is completed in this way, the magnetic card 2 can be issued, and the process can proceed to the next step 510.

In the next step 510, it is determined whether a magnetic card issuing command is sent from the POS terminal 7 to the magnetic card issuing device 6, and if it is sent, the process moves to the next step 5]1. Information such as the amount of money and the operator name of the POS terminal 7 is sent from the POS terminal 7 to the magnetic card issuing device 6 (step 511). When this information is manually input to the judgment means 11, the judgment means 11 , first drive the motor 93 and drive the rollers 86, 87, 88, 89, 9
1.92 is rotated to take out only one magnetic card 2 from the card holder 3, and the motor 59 is rotated (step 512). As a result, the magnetic card 2 is transported by the rollers 53.52. The magnetic head 5 of the reading means 10 moves within the rail body 16 of the mechanism 13 and moves from the second magnetic recording area 9 of the magnetic card 2 to the magnetic head 5 of the reading means 10.
7 is read out (step 513).
).

The code Cd read in this way is determined by the determining means II.
, the code Cm previously stored in ROM etc.
(step 514), the determination means 11 compares the preset code Cm with the read code Cd.
When a match is detected between the two codes (step 515), the year, month, day, hour, and minute are first read out from the timer provided inside the CPU, and the data is set to be the same as the data from the POS terminal 7 (step 516). ).

Then, the determining means 11 sends the write command Sc to the writing means 12.
At the same time, the above-mentioned data is given to the writing means 12 to write "advance payment amount, operator name, device code, date of issue, etc." to the first magnetic recording area 8 of the magnetic card 2 via the magnetic head 67. (step 517.5)
1B), and the recording of all information in the first magnetic recording area 8 of the magnetic card 2 is completed (step 518).
Step 511 to reset the program read from the IC card 4 stored in the RAM of the determination means 11.
), the magnetic card 2 is ejected from the slit A of the front panel 20, and the process ends.

On the other hand, in step 515, if the read code Cd does not match the pre-stored code Cm, the determining means 11 performs error processing (step 520), and the process ends.

In the above embodiment, the processing program is reset every time the magnetic card 2 is issued, but the processing program may be reset when a fixed number of magnetic cards 2 have been issued. can. Further, in the above embodiment, the processing program is reset by issuing the magnetic card 2 every - time, but the processing program may be reset by turning off the 11fi switch.

Therefore, even if the magnetic card issuing device 6 were to be stolen, the magnetic card issuing device 6 would not operate unless the IC card 4 was present, thereby preventing the issuance of unauthorized cards. Furthermore, since the IC card 4 is extremely difficult to tamper with, the safety and reliability of the system are improved. Also, I
Since the C card 4 detects the consistency of complicated protocols, etc., the consistency can be confirmed reliably, and the safety and reliability of the system are further improved. In addition, even if the magnetic card issuing device 6 is stolen, the magnetic card 2 will not be issued unless the code Cd written in the second magnetic recording area 9 of the magnetic card 2 matches the code Cm inside the device. It turns out you can't do it. Furthermore, even if the magnetic card issuing device 6 is stolen, the code Cd written in the second magnetic recording area 9 of the magnetic card 2 where the magnetic card issuing device 6 was installed can be immediately retrieved. By changing to a different code, unauthorized issuance of the magnetic card 2 can be prevented.
