PROBLEM TO BE SOLVED: To provide a game machine which can achieve the return of rotating bodies to their starting-points at a low cost when a power interruption occurs during the rotation of the rotating bodies.SOLUTION: In a game machine, a performance control part drives a motor so that the rotation shaft is rotated in the forward direction 55A (S3901), and when a sensor 59 detects a groove of a Geneva mechanism (Yes at S3902), next drives the motor so that the rotation shaft rotates in the reverse direction 55B (S3903). After that, the performance control part now determines whether or not the sensor 57 detects the groove of the rotation shaft twice, namely whether or not two-time rotation as a prescribed number is performed (S3904). Such a determination is performed only by the detection of the sensor 57. When the sensor 57 detects the groove of the rotation shaft twice (Yes at S3904), the performance control part stops the reverse rotation regarding that the rotating bodies have arrived at the starting-point (S3905). |
