(random access memory), J e'B dot printer that outputs various print data, 17 a floppy disk device that stores and reproduces data on a floppy disk 19tlC inserted from a floppy disk insertion slot 18; 20 is an IC card reading/writing section.

The IC card reading/writing unit 2o is for reading data in the memory of the IC card 1 inserted from the card insertion slot 21, or writing data in the memory, and is connected to the card issuing machine main body by a cable 22. It is now possible to do so. That is, as shown in FIG. 5, a conveyor caliper 31 is provided to convey the IC card 1 inserted from the card insertion slot 21. The transport path 31 is provided with a plurality of pairs of rotatable transport rows 232, which are positioned so as to sandwich the IC card 1 from above and below when transporting it. The pair of transport rows 232 are provided at regular intervals along the transport path 3. The distance from the center of each of these transport rollers 32 to the center of the adjacent transport roller 32 has the width dimension in the card transport direction. Therefore, the transport path 31 of the IC card 1 is defined by the transport guide 334C.

Further, the CP in the IC card 1 is placed on the transport guide 33.
A reader/writer 34 is arranged to exchange data with U3. This reading/writing device 34 is electrically connected to the connecting section 2.

In addition, the IC card handling machine 10' that performs password verification is also
It has the same configuration as the C card issuing machine 10. however,
The control program in ROM 14 is different.

In addition, an example of an IC card handling machine that does not perform password verification is a card reader 50 installed at an amusement park, etc.)
It subtracts the contents of the card. That is, as shown in FIG. 6, it is composed of an IC card reading/writing section 51, a CPU 52 that controls the whole, a ROM 53 in which a control program is stored, and a RAM 54 for data storage. The IC card reading/writing unit 51 has the same configuration as the IC card reading/writing unit 20 described above.

Next, the issuance of an XC card in such a configuration will be explained. For example, now, the operator (issuer) sets the IC card issuing machine 10 to the IC card issuing mode using the key date 12, and inserts the IC card 1 into the card insertion slot 21. Then, the IC card reader/writer 34 and the connector 2 of the IC card 1 are electrically connected. ), CPU i is CRT

The signal corresponding to the above input and the signal indicating the issuing machine are CPU I.
The data is supplied from J to the CPU 3 via the IC chip reader/writer 34, the connector 2, and the interface circuit 5. Then, the CPU S stores the supplied control program in the ROM section (not shown) and stores the data in the data area 43 of the memory section 4. At this time, since the function does not perform password verification, the storage area 48 of the memory unit 4,
Nothing is stored in 4□. Then, the IC card 1 is issued from the card insertion slot 21.

Further, the CRT display device 13, which specifies whether or not to add a password verification function, provides guidance saying "Please enter your password." In response to this guidance, the operator selects key bead 1.
Enter your PIN number in step 2. A signal corresponding to this input and a signal indicating the issuing device are supplied from the CPU 11 to the CPU J via the IC chip reader/writer 34, the connecting section 2, and the interface circuit 5. Then, the CPU
S stores the supplied PIN number in storage area 4°,
The password verification bladder is stored in the storage area 4□.

Next, the CPU IJ connects the CRT display device 13.
``Please set the corresponding control program, data, etc.''. In response to this guidance, the operator inputs the control program, data, etc. using the key date 12. The signal corresponding to this input is sent from CPU J 1 to CPU
Supplied to S. Then, the CPU 3 stores the supplied control program in a ROM section (not shown), and stores the data in the data area 43 of the memory section 4. in this case,
The first process of the control program is a password verification function. Then, the IC card 1 is issued from the card insertion 121.

Next, a case will be described in which a customer handles the IC card 1 to which the PIN number issued as described above is attached. That is, the customer inserts the card into the card insertion slot 2 of the IC card handling machine 10'.

Then, the IC card 1 is connected to the IC card reader/writer 34 and the IC card reader/writer 34.
The connection section 2 in the C card 1 is electrically connected. Next, the CPU 11 displays the message "Please enter your password" on the CRT display device No. 3.

In response to this guidance, the customer enters his/her password using the keypad 12.

The signal corresponding to this input and the signal indicating the handling machine are CPU 1
1 to CPU 3. Then, the CPU 3 supplies the supplied password to the comparator circuit 7. At this time, the comparison circuit 2 is in a multi-operable state according to the flag from the storage area 4□, and the comparison circuit 2 is in a multi-operable state according to the flag from the storage area 4□. The PIN number is provided by. As a result, the comparator circuit 7
Compares the password supplied from U3 with the password from storage area 48, and outputs a match signal and a mismatch signal to CPU 3 as a result of this comparison.These signals are sent to CPU 3.
It is supplied from UJ to CPU J1. For this,
If the comparison result is a match, data can be accessed from the data area 4s of the memory section 4. Next, CPU 1
If a 1Fi match signal is supplied, it will be determined that the passwords match, and a message will be displayed on the CRT saying "Please enter your handling data".
This is done using the display device 13. As a result, the user handles the various types. Further, when a mismatch signal is supplied, the CPU 11 determines that the passwords do not match, and displays a message on the CRT display device 13 saying, "The password is incorrect. Please enter the correct password again."

Also, a case will be described in which a customer handles the IC card 1 issued as described in Q above and to which no PIN number is attached. That is, the customer inserts the card into a card insertion slot (not shown) of a card reader (an IC card handling machine that does not perform password verification) 5o installed at the amusement park. Then, the IC
In the card 1, the IC card reader/writer 34 and the connection section 2 of the IC card 1 are electrically connected. Then,
CPU5st outputs a data read signal to CPU3. Then, the CPU 5 reads the data area 4. of the data section 4.
Data (number of uses) is read from the CPU 52 and output to the CPU 52. At this time, since each of the seven password codes is not stored in the storage area 4□ of the memory section 4, the comparator circuit 7 is not activated. Is this it? ), CPU5;
t performs data subtraction processing and supplies the result to the CPU 3.

As a result, new data supplied from CPU 3d CPU' is used in data memory 4. Update the contents of.

Then, the IC card 1 is returned through the card insertion slot (not shown).

In the above embodiment, the verification of the password on the IC card was performed by the comparison circuit, but the verification is not limited to this, and the verification may be performed by the CPU.
