Claims

[Claim for Utility Model Registration] The tray moves between the disc ejecting position and the playback position for loading or unloading with respect to the chassis, and a signal reproducing unit provided so as to be movable up and down to the chassis is used for loading or unloading. In a disk loading device equipped with a signal reproducing unit lifting mechanism, the turntable is moved up and down so that it is pressed against the clamper after the tray is stopped, and moved down before the tray is moved during unloading. The mechanism is engaged with a drive gear for driving the tray, a slider provided on the chassis to move in the left and right directions in conjunction with the drive gear, and at least two positions in the left and right directions of the rotating tip of the signal reproducing unit. 1. A disk loading device comprising: a cam portion provided on a slider;
