PROBLEM TO BE SOLVED: To provide a game machine provided with an overcurrent suppression means for suppressing an excessive inflow current from flowing into a switch circuit provided with a transistor. SOLUTION: This game machine is provided with resistors 108 and 109 and a logic circuit so as to detect that a current flowing to a MOS transistor 105 as a switch for conducting a driving current is an overcurrent. When the overcurrent flows to the MOS transistor 105, the transistor inside the logic circuit 110 is turned on and overcurrent detection signals are outputted. Thus, a switch 115 is turned on. As a result, an input current flowing from the side of an input electrode IN flows through the switch 115 to a ground electrode GND. Thus, the respective MOS transistors 105, 106 and 107 are turned off and the MOS transistor 105 is protected from the continuous flow of the excessive inflow current.
