PROBLEM TO BE SOLVED: To provide a game machine capable of detecting states of a plurality of movable members by single detection means.SOLUTION: The game machine comprises: detection means that includes a first movable member having a first detection object part with translucency, a second movable member having a second detection object part with translucency, a light-emitting element, and a light-receiving element, and that outputs a signal on the basis of a light-receiving state of the light-receiving element; and operation control means causing the first movable member and the second movable member to operate in prescribed modes respectively. The operation control means can change over among a first state where the first detection object part and the second detection object part are overlappedly present between the light-emitting element and the light-receiving element, a second state where any one of the first detection object part and the second detection object part is present between the light-emitting element and the light-receiving element, and a third state where neither the first detection object part nor the second detection object part are present between the light-emitting element and the light-receiving element. The detection means outputs a different signal according to the first state, the second state, and the third state respectively. |
