PURPOSE:To restore a clamper to the normal state by providing a clamp detection switch to only give an ejection instruction externally at a faulty state of the clamper. CONSTITUTION:A clamper detection switch 8 detecting whether or not a clamper 8 is descended is turned on when the clamper 6 lifts up and is turned off when the clamper is descended. Since a sensor 3 is turned on when no disc 4 exists, whether or not the clamper detection switch 8 is turned off is decided. In this case, since the clamper detection switch 8 is turned off, a roller 7 is reversed and the ejection is started. The clamper 6 is restored to the normal state according to the ejection. It is desired to set the time when the roller 7 is driven so that the clamper 6 is restored sufficiently.
