PROBLEM TO BE SOLVED: To miniaturize control baseboards, to reduce cost, to prevent a game player from receiving a disadvantage by a power source interruption state, and also to optionally cancel storage in a RAM. SOLUTION: A main control baseboard 22, a discharge control baseboard 24, a pattern display control baseboard 29, a voice control baseboard 20 and a lamp control baseboard 31 are connected to a power source baseboard 34. The power source baseboard 34 is provided with four power source generating circuits for generating from AC 24 V to DC 5 V, DC 12 V, DC 24 V or DC 30 V and power sources generated by the respective power source generating circuits are supplied to the corresponding control baseboards 22 and 24. One capacitor 78 is disposed in the power source baseboard 34 in order to back-up RAMs which are disposed in the main control baseboard 22 and the discharge control baseboard 24. Besides, a RAM clear switch 69 for initializing the RAMs of the both control baseboards 22 and 24 is disposed in the power source baseboard 34.
