PROBLEM TO BE SOLVED: To provide a game machine which enables an individual control means to accurately receive commands from the game control means. SOLUTION: The voltage of a positive 30 V power source which makes an IC 901 for monitoring power sources output a signal is set to the same voltage of another positive 30 V power source which makes an IC 931 for monitoring power sources output a signal. The ICs 901 and 931 for monitoring power sources herein used are of the same type of IC. As a result, when the power source voltage goes down, an NMI interruption is applied to a CPU 371 for controlling prize balls of a prize ball control board 37 at the same timing as that at which the NMI interruption is applied to the CPU 56 of the main board 31. The individual CPUs stop the normal control in response to the NMI interruption, hence making the CPU 56 of the main board 31 and the CPU 371 for controlling prize balls start at the same timing.
