PROBLEM TO BE SOLVED: To perform a highly reliable inspection for control of a CPU based on detection signals. SOLUTION: In the game machine comprising a detection means for detecting the entry of a game ball to a winning part, a game controller for generally controlling a game on the basis of a detected result from the detection means, and a variable winning device provided to the winning part, a signal take-out region for outputting signals to be changed according to a game state to the outside of the game controller is formed by providing a prescribed wiring pattern to a circuit board, control command signals for driving the variable winning device are transmitted from the output part of an output port circuit to the signal take-out region at all times, and also the detection signals from the detection means are transmitted from the output part of an irreversible signal transmission circuit to the signal take-out region at all times.
