PROBLEM TO BE SOLVED: To provide a game machine which can prevent a malfunction of a computer circuit caused by noises from the power source or the like even when a power source line is extended too longer and regardless of a possible increase in the quantity of power supplied to it. SOLUTION: In respective circuit boards arranged are the main control part, a shooting control part, a putout control part, a sub control part which executes a vocal performance and a picture performance synchronizing each other following commands from the main control part and a power source part for supplying necessary power source voltages to parts of devices based on an AC voltage received from outside. The main control part, the putout control part and the sub control part accomplish controlled operations with computer circuits arranged on the respective circuit boards. All of the power source voltages of the computer circuits are generated by lowering the DC voltages received from the circuit board of the power source part with stabilized power source circuits arrayed in the respective circuit boards.
