PROBLEM TO BE SOLVED: To cause a pay-out control device to accurately receive, without reception errors, a prize-ball command transmitted from a main control device and use an interruption NMI terminal both for interruption by the reception of the prize-ball command and for data backup during a power outage. SOLUTION: A gate circuit 6 is provided which outputs a signal when there is either a strobe signal transmitted according to the prize-ball command or a voltage drop signal transmitted from a source voltage monitoring circuit 7 according to the drop of voltage at a power supply. The output terminal of the gate circuit 6 is connected to the NMI terminal of the pay-out control device 3 to input the strobe signal and the voltage drop signal to the respective input ports of the pay-out control device.
