The reader / writer antenna unit 32 can communicate with the IC card 11 at the frequency (13.56 MHz) via the first antenna unit 22 and the second antenna unit 24, and the IC card 11 is inserted into the reader / writer antenna unit 32. When inserted into the discharge unit 31, the first antenna unit 22 and the second antenna unit 24 are arranged at positions facing each other. That is, the reader / writer antenna unit 32 is a single unit and serves to communicate with both the first antenna unit 22 and the second antenna unit 24 of the IC card 11.

  The control unit 33 controls the device as a whole and makes the host device 13 accessible via the network 14, specifically, a control circuit, a memory, a power supply circuit, a transmission circuit, a modulation / demodulation circuit. It is an IC chip provided with a circuit, a power amplifier circuit, and a detector circuit as appropriate. The insertion / ejection unit 31, the reader / writer antenna unit 32, and the control unit 33 constitute a reader / writer in a broad sense.

  That is, the control unit 33 requests an ID code from the first control unit 21 of the IC card 11 inserted into the insertion / ejection unit 31, accesses the host device 13 based on the ID code, and retrieves the ID code from the player database. The display data is created by extracting the stored data (game media savings and balance data) associated with the ID code, and the second control unit 23 of the IC card 11 uses a protocol different from the communication protocol for the ID code request. At least the transmission control is performed.

At least.

  The host device 13 includes at least a player database 41, and other configurations are omitted. As shown in FIG. 2 (B), the player database 41 stores the number of game medium savings (number) associated with each ID code and the remaining data for the prepaid function for each ID code. It is.

  FIG. 4 shows a processing flowchart as a premise of the card display of game holding data according to the present invention, and FIG. 5 shows a processing flowchart of the card display of game holding data according to the present invention. 4, when the gaming machine IC card 11 is inserted into the insertion / ejection unit 31 of the information management apparatus 12, the control unit 33 receives an IC card insertion signal from the insertion / ejection unit 31 (step (S 1). The control unit 33 transmits the ID code request command superimposed on the carrier wave of the frequency F (13.56 MHz) from the reader / writer antenna unit 32 to the inserted IC card 11 using the communication protocol (S2).

  In the first control unit 21 of the IC card 11, the first IC chip is activated by the induced electromotive force generated by the carrier wave received by the first antenna unit 22, and the held ID code is transmitted to the information management apparatus 12 side by the communication protocol. (S3). In the information management device 12, the control unit 33 accesses the host device 13 via the network 14 based on the acquired ID code, and stores the number of game media stored in association with the ID code from the player database 41. And the retained data of the balance is extracted (S4).

  Subsequently, each time the control unit 33 makes a change in the decrease due to the deposit or use of the remaining amount during the game by the player and a change in the number of game media saved, the remaining amount associated with the ID code with respect to the player database 41 And the holding data of the number of game medium savings is updated (S5). Further, the control unit 33 displays the retained data on the display unit 34 every time the data is updated (S6).

  And said S5 and S6 are repeated until the eject button from the operation part 35 by a player is pushed (S7).

  Therefore, when the player presses the eject button on the operation unit 35 (S7), as shown in FIG. 5, the control unit 33 receives an eject signal from the operation unit 35 (S11) and is inserted. An ID code request command superimposed on a carrier wave having a frequency F (13.56 MHz) is transmitted from the reader / writer antenna unit 32 to the IC card 11 using the communication protocol (S12).

  In the first control unit 21 of the IC card 11, the first IC chip is activated by the induced electromotive force generated by the carrier wave received by the first antenna unit 22, and the held ID code is transmitted to the information management apparatus 12 side by the communication protocol. (S13). S12 and S13 are for final reconfirmation, and are not particularly necessary processes.

  Therefore, the control unit 33 of the information management device 12 accesses the host device 13 based on the acquired ID code, and retains the number of game media saved and the remaining money associated with the current ID code from the player database 41. Data is extracted (S14). The extracted number of game media saved and the retained data of the balance are used as display data, and a parity check flag is attached to the display data for the IC card 11 and superimposed on a carrier wave of frequency F (13.56 MHz). Transmission is performed using a different protocol (S15).

The display data is subjected to a parity check from the attached parity check flag, and the result is transmitted to the information management apparatus 12 side (S16).

  As a result of the parity check (S17), in the case of mismatch, a negative response (NAK) is transmitted to the information management device 12 side, so that the display data is retransmitted from the information management device 12, and the second control unit 23 responds to this. Also for parity check, the result is transmitted to the information management apparatus 12 side (S15 to S17).

  As a result of the parity check (S17), if they match, a response (ACK) is transmitted to the information management device 12 side, the display control unit 27 rewrites the display of the balance on the first display unit 25, and the second display unit 26 The display of the number of game medium savings for is rewritten (S18). And the 2nd control part 23 transmits the completion | finish signal of the display rewriting by timing etc. to the information management apparatus 12 side (S19).

  The control unit 33 of the information management apparatus 12 receives the display rewriting end signal and discharges the IC card 11 from the insertion / discharge unit 31.

As described above, the first IC chip of the first control unit 21 is changed to an existing high security IC chip compatible with ISO18092 as described above, and the antenna unit or the like can be changed only by changing the program of the control unit 33 of the information management device 12. The first control unit 21 and the second control unit 23 can communicate with the information management apparatus 12 without changing the mechanism of the reader / writer part, and the player database 41 of the player is stored on the IC card 11. The stored data stored can be displayed.

  By the way, although the said embodiment demonstrated as a case where the IC card 11 did not memorize | store a player's holding | maintenance data in the 1st control part 21, the said 1st control part 21 (1st IC chip) was provided with memory corresponding. Data of contents displayed on the first display unit 25 and the second display unit 26 may be stored.

  In this case, the information management device 12 acquires the ID code and stored data from the IC card 11 inserted into the insertion / ejection unit 31, and holds data (game medium) from the player database 41 based on the acquired ID code. It is also possible to extract, compare and confirm the number of savings and balance). Further, when the retained data fluctuates during the game of the player and the retained data in the player database is updated, the data stored in the IC card 11 may be updated each time.
