Claims (1)

[Scope of utility model registration request] It has a pick-up section that plays back a disk as a recording medium, and a pick-up section moving body that moves from a standby position that allows disk loading after the disk is loaded to a position facing the disk, and is interlocked with the movement of the pick-up section moving body. and a disk lifting mechanism that lowers the disk placed in a predetermined position onto the turntable by inserting a case containing the disk and removing the case, and a disk lifting mechanism that lowers the disk placed in a predetermined position onto the turntable when the main power supply is cut off. A disk playback device comprising a backup power source for supplying power to a motor that drives the pickup moving body to lower the pickup unit, a detection means for detecting that the case is inserted into the device; A disc playback device comprising means for cutting off the supply of the backup power to the motor and stopping the movement of the pickup section moving body when the detection means detects that the case is inserted.
