For this purpose, the present invention provides an electronic control circuit board on which electronic components such as a central processing unit for controlling game contents and a memory element are mounted on a back surface of a game machine. In a pachinko gaming machine in which the control circuit board is covered by a transparent case, a transmitter / receiver that wirelessly transmits an abnormality detection signal when an electromagnetic wave that causes the electronic control circuit board to malfunction is provided inside the transparent case, A game machine is provided with a repeater for notifying an external device through a telephone line when an abnormality detection signal transmitted from the receiver / transmitter is received. Further, the present invention is characterized in that in the above-mentioned pachinko gaming machine, the repeater is externally controlled through a telephone line so that a signal transmitted wirelessly from a transmitter / receiver can be externally confirmed. Further, the present invention provides the pachinko gaming machine, wherein a plurality of pachinko gaming machines are provided with a receiver / transmitter provided with a unique identification signal for each of a plurality of pachinko gaming machines, and the identification signal is wirelessly transmitted to a repeater. It is characterized by the following.

[0006]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the back surface of a pachinko gaming machine according to the present invention, FIG.
Is a winning ball collecting case fixed to the back of the game board, 3 is a mounting plate made of a rectangular stainless steel plate fixed to the mounting portion of the winning ball collecting case 2, and 4 is fixed to the mounting plate with screws 5. An electronic control circuit board which is a rectangular printed circuit board. On the electronic control circuit board 4, a liquid crystal display device 12 provided on the game board 1 is operated to generate a jackpot at a predetermined establishment, and various electric opening and closing winning devices 13
And a central processing unit (CPU) and storage elements (RAM, RO) for controlling the game contents of the pachinko gaming machine.
Many electronic components 6 such as M) are mounted. Reference numeral 7 denotes a connector provided on the electronic control circuit board.

Reference numeral 8 denotes a plastic transparent case fixed with screws 9 so as to cover the electronic control circuit board 4.
Inside the transparent case 8, there is provided a transmitter / receiver 10 for wirelessly transmitting an abnormality detection signal when receiving an electromagnetic wave that causes the electronic control circuit board 4 to malfunction. Numeral 11 denotes an antenna installed on the inner surface of the transparent case to receive such an electromagnetic wave. The transmitter / receiver 10, as shown in FIG. 3, includes a receiving circuit, an abnormality detecting circuit, and a wireless transmitting circuit.
Also, the receiving / transmitting machine 10 has a number of pachinko gaming machines installed in a game arcade, and a unique identification number for each machine is described in its configuration ROM, and the identification signal and the abnormality detection signal are transmitted through a wireless transmission circuit. It is configured to wirelessly transmit to the repeater 15. The power supply for operating the transmitter / receiver 10 can be sufficiently provided by a button battery or the like, but may be obtained from the electronic control circuit board 4 if necessary.

[0008] As shown in FIG. 4, for example, the repeater 15 is installed on a ceiling surface above a number of pachinko game machines installed in a game arcade. The repeater 15 includes an antenna and a receiver for receiving a signal transmitted wirelessly from the receiver / transmitter 10, and a line connection device connected to a public telephone line.
When an abnormality occurrence signal is received from the transmitter / receiver 10, it automatically dials a telephone number registered in advance in the line connection device, and reports the fact of the abnormality occurrence to a manager or a supervisory control authority through a telephone line. Is displayed on the display.

In this case, by reporting the occurrence of the abnormality together with the machine identification signal, it is possible to simultaneously know which machine of the game arcade has caused the abnormality, and to take more appropriate measures. . If this line connection device is connected to a wireless telephone line such as a PHS, the repeater 1
5 is easy to install without requiring wiring work for telephone lines. Optical communication such as infrared light may be used as a wireless communication means between the transmitter / receiver 10 and the repeater 15.

If the repeater 15 can be controlled from the outside through a telephone line, the repeater 1 is always or periodically logged in to the line connection device through the telephone line and
5 to check the signal transmitted wirelessly from the transmitter / receiver 10 of each pachinko gaming machine, and from the response signal, it can easily confirm whether each pachinko gaming machine is operating normally from a remote place. Become like
