PROBLEM TO BE SOLVED: To solve the problem that a conventional Pachinko game machine does not allow the detection of the disconnection of wiring of a game ball detection switch or the disconnection of a connector. SOLUTION: A game machine has a main CPU 31 judging the case where the comparison result of a first comparator 84 shows an output voltage V of a start winning ball switch 21S lower than a reference voltage (3 V) and the comparison result of a second comparator 90 shows an output voltage V of the start winning ball switch 21S higher than a judgement voltage (0.5 V) as the presence of passage of a Pachinko ball. The game machine judges the case where the comparison result of the first comparator 84 shows an output voltage V of a start winning ball switch 21S lower than the reference voltage and the comparison result of the second comparator 90 shows an output voltage V of the start winning ball switch 21S lower than the judgement voltage as the presence of an abnormal state and the absence of the passage of a game ball.
