The logic circuit 72 detects return data from the EEPROM 67 when detecting a data request signal as data based on the demodulation result of the demodulation circuit 71, and outputs the return data detection result to the modulation circuit 73. The modulation circuit 73 generates a data return signal based on modulating the return data detection result, and varies the impedance based on turning on and off the resistor 74 based on the data return signal generation result.

  The reader 65 is carried by a pachinko hall clerk, and as shown in FIG. 7, an antenna coil 66, an oscillation circuit 75, a transmission circuit 76, a reception circuit 77, an A / D conversion circuit 78, a control circuit 79, and an operation switch. 80 and a display 81. The control circuit 79 is configured mainly with a microcomputer and has a CPU, a ROM, and a RAM. The control circuit 79 transmits a data request signal to the transmission circuit 76 based on the determination that the operation switch 80 has been operated. The transmission circuit 76 stores an AC waveform of a constant frequency oscillated from the oscillation circuit 75 as data. By modulating based on the reception result of the request signal, the data request signal is transmitted on the carrier wave from the antenna coil 66 to the antenna coil 63 of the IC tag 59. The current flowing through the antenna coil 66 changes in accordance with the fluctuation of the impedance of the IC tag 59, and the data return signal transmitted from the IC tag 59 is received by the antenna coil 66 as a change in current. The reception circuit 77 detects the current flowing through the antenna coil 66, and the AD conversion circuit 78 AD converts the detection result of the reception circuit 77 and outputs the result to the control circuit 79.

  FIG. 8 shows timer interrupt processing that the CPU of the control circuit 79 starts periodically at a constant time interval ΔT. The timer interruption process is performed based on a control program recorded in advance in the ROM, and the CPU determines whether or not the A / D conversion flag is turned off in step S1. The A / D conversion flag is initially set to an off state based on the power supply to the control circuit 79, and the CPU determines in step S1 that the A / D conversion flag is off. Sometimes, the process proceeds to step S2, and it is determined whether or not the operation switch 80 is operated. The operation switch 80 is electrically turned off in a non-operation state in which no operation force is applied, and is electrically turned on in an operation state in which the operation force is applied. The CPU turns on the operation switch 80 in step S2. Whether or not the operation switch 80 is operated is determined based on whether or not the operation switch 80 is operated.

  When the CPU determines that the operation switch 80 is turned on in step S2, the CPU outputs a data request signal to the transmission circuit 76 in step S3. This data request signal is recorded in advance in the ROM of the control circuit 79. When the CPU outputs the data request signal in step S3, the CPU sets an A / D conversion waiting time in the timer T in step S4. This A / D conversion waiting time is recorded in advance in the ROM of the control circuit 79. When the CPU sets the timer T in step S4, the CPU proceeds to step S5 and sets the A / D conversion flag to the on state. .

  When the A / D conversion flag is on, the CPU proceeds from step S1 to step S6, and determines whether or not there is a data return signal from the A / D conversion circuit 78. When it is determined that there is a data return signal from the A / D conversion circuit 78, the process proceeds to step S7, and a normal message is displayed on the display unit 81. This normal message informs the carrier of the reader 65 that there is a normal state in which fraud has not been performed. When the normal message is displayed in step S7, the CPU turns off the A / D conversion flag in step S8. Reset to state.

  If the CPU determines that there is no data return signal from the A / D conversion circuit 78 in step S6, the CPU subtracts the unit time ΔT recorded in advance in the ROM from the timer T in step S9, and the subtraction result of the timer T in step S10. It is compared with the limit time “0” recorded in the ROM in advance. If it is determined that “T = 0”, an abnormal message is displayed on the display 81 in step S11. This abnormal message notifies the carrier of the reader 65 that there is an abnormal state in which an illegal act is being performed. When the CPU displays the abnormal message in step S11, the CPU turns off the A / D conversion flag in step S8. Reset to state.

According to the said Example 1, there exists the following effect.
A resin sealing portion 52 is formed based on filling the main substrate box 35 with a liquid silicone gel, and the main control circuit 24, the main substrate 36, the front box 42, and the rear box 43 are respectively connected to the resin sealing portion 52. In order to illegally replace the regular main control circuit 24 with an illegal one, the rear box 43 is removed from the front box 42 against the adhesiveness of the resin sealing portion 52. In addition to the removal operation, it is necessary to perform the operation of peeling the resin sealing portion 52 from the main control circuit 24 and the main substrate 36 against the adhesiveness of the resin sealing portion 52. For this reason, a great deal of effort is required to illegally replace the main control circuit 24, so the deterrence of the main control circuit 24 against unauthorized replacement increases.

  An IC tag 59 was embedded in a region formed by projecting the main control circuit 24 to the rear side opposite to the main substrate 36. For this reason, the fraudster removes the rear case 43 from the front case 42 against the adhesiveness of the resin sealing portion 52 and scrapes a part of the resin sealing portion 52 that covers the main control circuit 24 from behind. If the main control circuit 24 is to be removed from the main board 36 on the basis thereof, the IC tag 59 is scraped off together with a part of the resin sealing portion 52. Therefore, when the main control circuit 24 is illegally exchanged, the IC tag 59 is removed from the resin sealing portion 52 together with the main control circuit 24. Therefore, the data request signal is transmitted from the reader 65 to the reader 65. Based on the fact that the data return signal is not returned, the unauthorized exchange of the main control circuit 24 can be reliably detected.

  The entire IC tag 59 was embedded in the region between the capacitors 41 in the region where the main control circuit 24 was projected rearward of the resin sealing portion 52 on the side opposite to the main substrate 36. For this reason, when a fraudulent person tries to remove the main control circuit 24, the possibility of scraping the resin sealing portion 52 from the back of the main control circuit 24 is increased, so that a part of the resin sealing portion 52 is scraped off. Accordingly, when the main control circuit 24 is to be removed from the main board 36, the IC tag 59 can be surely scraped together with a part of the resin sealing portion 52. Since the injection port 53 facing the main control circuit 24 from the rear is formed in the main substrate box 35 and liquid silicone gel is injected into the main substrate box 35 from the injection port 53, the main control circuit is utilized using the injection port 53. The IC tag 59 can be inserted in the area behind 24.

  Since the colorless and transparent IC tag 59 is embedded in the colorless and transparent resin sealing portion 52, it is difficult for an unauthorized person to recognize the presence of the IC tag 59. For this reason, when an unauthorized person attempts to illegally replace the authorized main control circuit 24 based on the fact that a part of the resin sealing portion 52 is scraped off, the IC tag 59 is attached to the resin sealing portion 52. It will be scraped off with a part. Therefore, when the main control circuit 24 is tampered with, the IC tag 59 is removed from the resin sealing portion 52 together with the regular control circuit 24. Therefore, the reader 65 is in spite of the data request signal transmitted from the reader 65. The illegal exchange of the main control circuit 24 can be found based on the fact that no data return signal is returned.

In the first embodiment, a prize ball control circuit may be mounted on the main board 36 instead of the main control circuit 24.
In the first embodiment, the main substrate box 35 may be filled with a solid resin sealing portion that is not gel-like instead of the gel-like resin sealing portion 52 having adhesiveness.
