装置。 A tray is supported so as to be slidable between an attachment/detachment position where the disk is attached/detached and a storage position where the disk is mounted on the turntable, and the tray moves to the storage position in conjunction with the sliding movement of the tray. In a disc player configured such that a clamp plate that clamps the disc on a turntable when the disc is displaced is displaced from a non-clamping position to a clamping position, a motor for driving the tray and a motor for driving the tray and a clamp plate that clamps the disc on the turntable when the disc is displaced from the turntable are provided. a signal generating circuit that generates a signal until the tray is displaced to the attachment/detachment position, and generates a signal having a voltage level higher than that of a signal generated thereafter at a predetermined time from the opening operation of the tray; and a motor drive circuit that drives the motor according to the drive conditions, and the drive voltage generated from the motor drive circuit is made high for a predetermined period of time from when the tray is opened. Device.
