PROBLEM TO BE SOLVED: To provide a game machine allowing respective control means to surely receive a command from a game control means. SOLUTION: A voltage of +30 V power supply by which a power supply monitor IC 901 outputs signals is set to the same as a voltage of +30 V power supply by which a power supply monitor IC 931 outputs signals. A same brand IC is used for the power supply monitor ICs 901 and 931. When the power supply voltage gradually falls off, NMI (Non-Maskable Interrupt) occurs in a prize ball control CPU 371 of a prize ball control board 37 at the same timing as when NMI occurs in the CPU 56 of the main board 31. The respective CPUs stop the regular controls according to the NMI. That is to say, the CPU 56 of the main board 31 and the prize ball control CPU 371 fall at the same timing.
