PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing a cost rise of a case corresponding to a request to be asked for a constitution to realize a rotation performance of a rotor.SOLUTION: At the time of rotation of a rotation shaft 82, either of opposing sensors 57 and 58 detects a groove so that the state of the rotation shaft 82, that is, the direction of a front face of an upper performance part or a lower performance part is grasped. At the rotation of the rotation shaft 82, a sensor 59 detects the groove of a Geneva mechanism thereby to grasp what rotation the rotation shaft 82 has made. More specifically, the sensor 59 is arranged to detect in the case where the rotation shaft 82 is between 1.5 rotations and 2 rotations. In the case of a rotation in the direction of an arrow, if the position of the groove of the rotation shaft 82 is detected by the sensor 57 after the groove of the Geneva mechanism is detected by the sensor 59, it is possible to grasp that the time is after two rotations from an origin. |
