IPC: G11B17/056
Filed: 1995-03-23
Abstract: PURPOSE: To prevent a disk from slipping down when the device is inclined. CONSTITUTION: In a disk player, holding force (p) of a gear 22 for the purpose of holding a tray 13 in an open position is set to a prescribed value. Then, the weight of the tray 13 is set to a prescribed value, so as to make force to be applied to the gear by weighting of the tray 13 and the disk 1 equivalent to or larger than the holding force (p) when the device is inclined at more than a prescribed angle. Consequently, when the disk player is inclined, the tray 13 is started to slide backward against the holding force (p) of the gear 22 by weighting of the tray 13 and the disk 1. In this case, a projecting part 26 is separated from an open switch 27 to turn off this switch. A motor gear 23 is driven by a control means upon detection of this switching off to close the tray 13.  Thus, when the disk player is inclined, the tray 13 is automatically closed, and the disk 1 is prevented from slipping down into the device.
