PROBLEM TO BE SOLVED: To facilitate the inspection of a game machine regarding unauthorized alteration without affecting transmission of signals from a main board to other boards. SOLUTION: A Pachinko game machine 1 is provided with a relay board 100C having a diode 30 between the main board 100A and a sub board 100B, and the reception interface 112 of the sub board 100B is provided with a resistor 113, a buffer 115 and a filter 116 for setting the L level of control signals in the order. Thus, by confirming the relay board 100C, whether or not measures against the unauthorized alteration are taken is easily inspected, and a communication speed between the main board 100A and the sub board 100B is prevented from becoming lower than before while preventing the output current of the main board 100A from being excessive. That is, the inspection of the game machine regarding the unauthorized alteration is facilitated without affecting the transmission of the signals from the main board 100A to the sub board 100B.
