PROBLEM TO BE SOLVED: To provide a game machine capable of reutilizing a conventional Pachinko machine main body or having control substrates allowing the use of a conventional tester and coping with a low voltage. SOLUTION: This game machine is provided with a main control substrate 1 controlling a game and a sub-control substrate 2 controlling various devices based on the output signal outputted from the main control substrate 1. The operating voltage of the sub-control substrate 2 is set lower than the voltage of the output signal outputted from the main control substrate 1. An output buffer 71 formed with an IC and having a voltage converting function is provided on the output side of the main control substrate 1, and the voltage of the output signal outputted from the main control substrate 1 is made higher than the operating voltage. An input buffer 72 formed with an IC and having a voltage converting function is provided on the input side of the sub-control substrate 2, and the voltage of the output signal from the main control substrate 1 is converted into the operating voltage of the sub-control substrate 2.
