<p>PROBLEM TO BE SOLVED: To provide a game machine capable of reducing the uselessness of a signal line for an external output while preventing a fraudulent act to be conducted at the power activation time of the game machine.SOLUTION: If it is judged that the difference between a game ball number detected by a start port switch 14a (or a proximity switch) and a game ball number detected by a winning confirmation switch 14b (or a photo-sensor) exceeds a predetermined threshold value (10 or more in this example), it is judged that an abnormal winning in a startup winning port 14 has occurred. On the basis of the fact that a predetermined signal output condition holds, including that an initialization has been executed at a power activation time, and that an abnormal winning in the startup winning port 14 has occurred, moreover, a security signal is outputted to the outside of a game machine. In this case, when the initialization processing has been executed and when it is decided that a predetermined error has occurred, a security signal is outputted from a common output terminal (i.e., a common connector CN7 of a terminal substrate) disposed in the game machine.</p> |
