PROBLEM TO BE SOLVED: To provide a game machine suppressing occurrence of malfunction as much as possible in a circuit configuration in that a plurality of processors function at an appropriate supply voltage level each.SOLUTION: A performance control part 22 for controlling performance operation including a voice performance is configured to include: a one-chip microcomputer 40; a program ROM 41; a voice synthesis circuit 42 for reproducing a sound signal required for the voice performance; a voice ROM 43 for storing voice data; voltage generation parts CONV1-CONV3 for generating a supply voltage at a level lower than 5 V, based on a 12-V DC voltage received from a power supply board 20, and for supplying the supply voltage to the one-chip microcomputer 40 and the voice synthesis circuit 42; and a reset part for generating a reset signal RSET based on the 12-V DC voltage received from the power supply board 20. When the 12-V DC voltage drops, the one-chip microcomputer 40 and the voice synthesis circuit 42 are reset based on the reset signal RSET. |
