摘要：PROBLEM TO BE SOLVED: To obtain game ball detection in a game machine with high reliability. SOLUTION: The game machine is equipped with a light emission section and a light receiving section, and also has a photosensor detecting the passage of game balls, a driving means pulse driving the light emitting section in a first period, a time measuring means measuring time on the basis of a second period shorter than the first period, a measured value acquisition means reading measured value of the time measuring means in response to the point of change of a light reception signal from the light receiving section and then clearing the measured value, a state determination means determining a first state showing that the photosensor is executing a prescribed operation, a second state showing that a game ball has passed between the light emitting section and the light receiving section, or a third state showing that the photosensor is performing an abnormal operation other than the first state and the second state on the basis of the result of comparison in which the measured value is compared with a plurality of set values, an information output means outputting a signal showing the second state to other control boards in the game machine when the state determination means outputs the second state and outputting a signal showing the third state to the outside of the game machine when the state determination means outputs the third state.
