7, a display section 8 for data and messages, and a light emitting diode 9 for indicating that the IC card 1 is being accessed. Although not shown, the IC card 1 manually inserted through the card insertion slot 7 is held in the main body case 6a, and the card is automatically ejected when the access of the IC card 1 is completed. A mechanism is provided.

FIG. 1 shows an outline of the electrical configuration of the IC card 1 and the reader / writer 6, which will be described below.

First, in the IC card 1, the IC module 2
, A control unit 2a, an EEPROM 2b, a clock unit 2c for a clock function, and a driver 2d for driving the LCD panel 4. The EEPROM 2b has a unique function in a system using the IC card 1. PIN code XC and for example
The balance information RZ and the like corresponding to the issue price of the IC card 1 are stored. Further, the control unit 2a controls data rewriting of the EEPROM 2b and display control of the LCD panel 4 based on an input signal through the Hall IC 3, a clock signal from the clock unit 2c, and a program stored in advance. Specifically, the control unit 2a always displays the balance information RZ stored in the EEPROM 2b on the LCD panel 4 by numerals,
When a display switching command signal Sa described later is given through the hall IC 3, the personal identification code XC and the balance information RZ stored in the EEPROM 2b are displayed on the LCD panel 4 in an encrypted pattern.
Note that such a display may be performed with a predetermined time delay. Further, when a data rewrite command signal Sb described later is given through the Hall IC 3, the control unit 2a rewrites the balance information RZ stored in the EEPROM 2b according to the signal Sb.

On the other hand, in the reader / writer 6, reference numeral 10 denotes data reading means including a light source 10a, a charge-coupled device (hereinafter abbreviated as CCD) 10b, and an image processing unit 10c.

Of the LCD panel 4. In this case, the light source 10a is lit during a period in which the card feeding mechanism (not shown) holds the IC card 1. In the lit state, the LCD panel 4 is turned on.
The security code XC and the balance information RZ displayed in the encryption pattern are converted into electrical signals by the CCD 10b, and the electrical code is processed by the image processing unit 10c to read the security code XC and the balance information RZ. ing. Reference numeral 11 denotes a non-contact type data transmission means constituted by two coils 11a. Each coil 11a is connected to the hole IC3 of the IC card 1 when the IC card 1 is set through the card insertion slot 7. It is located so as to be in a magnetic coupling state in close proximity. Thereby, the data transmission means 11 can transmit the display switching command signal Sa and the data rewriting command signal Sb to the IC card 1 by electromagnetic induction.

Reference numeral 12 denotes a control unit including a microcomputer, which includes a security code XC and balance information from the image processing unit 10c.
Based on RZ and a program stored in advance, control is performed as shown in FIG. That is, when the IC card 1 is inserted into the card insertion slot 7, the control unit 12 first transmits a display switching command signal Sa to the hall IC 3 of the IC card 1 through the data transmission unit 11. As a result, in the IC card 1, the password XC and the balance information R are displayed on the LCD panel 4.
Z will be displayed in a cryptographic pattern.

Next, the control unit 12 determines whether the personal identification code XC is correct,
When it is determined that the IC card 1 is not correct, the fact that the IC card 1 is unusable is displayed on the display unit 8, and a card feeding mechanism (not shown) is driven to return the IC card 1 in the set state. When the control unit 12 determines that the password XC is correct, the control unit 12 displays the balance amount indicated by the balance information RZ on the display unit 8 and displays the balance amount on the load 13 (for example, at a playground equipment at an amusement park or at a ski resort). It is determined whether or not the price required to drive the automatic gate of the ski lift landing is higher than the price required for driving the IC card 1. If the price is insufficient, the fact that the balance of the IC card 1 is insufficient is displayed on the display unit 8, The IC in the set state by driving the card feed mechanism

When the balance indicated by the balance information RZ is not insufficient, the control unit 12 transmits the load 13 to the communication interface.
While driving through 14, the data rewriting command signal Sb such that the balance information RZ is reduced by the amount required for driving the load 13 is transmitted through the data transmitting means 11,
After that, the IC card 1 is returned. Therefore, when the data rewriting command signal Sb is transmitted, the IC card 1 performs an operation of rewriting the balance information RZ stored in the EEPROM 2b so as to reduce the balance information RZ by the price. The contents displayed on the display unit 8 are initialized after the IC card 1 is returned. Although not shown in FIG. 3 for the control unit 12,
The history of the data rewriting of the IC card 1 and the driving status of the load 13 as described above are stored in the memory 15. Further, reference numeral 16 denotes a stabilized power supply for the control unit 12.

Therefore, according to the above configuration, in a normal state in which the IC card 1 is not set in the reader / writer 6, the balance information RZ stored in the EEPROM 2b is displayed as a number on the LCD panel 4 of the IC card 1. The user can visually check the display on the LCD panel 4 to check the balance information of the IC card 1.
RZ can be easily known. The LCD panel 4 for performing the above-mentioned display is also used as a data transmission means from the IC card 1 side to the reader / writer 6 side. As described above, the structure is not complicated, and at the time of data transmission using the LCD panel 4, the display on the LCD panel 4 is performed in an encrypted pattern, so that security can be improved at the same time.
