Claims

[Scope of Claim for Utility Model Registration] 1. A slider that engages with disc toilets stored in upper and lower stages in a magazine is moved in and out of the loading chassis by a tray moving mechanism,
In a multi-disc player in which a disc tray is transferred to a turntable by the lifting and lowering movement of a loading chassis, the tray moving mechanism is configured to slow down the loading/unloading speed near the end of the drawer and near the end of the storage. Tray loading device for multi-disc players. 2. The tray moving mechanism has a loading arm that is engaged with the linearly moving slider so that it can slide in a direction perpendicular to the moving direction, and the loading arm is pivoted at approximately the midpoint near both of the above. 2. The tray loading device for a multi-disc player according to claim 1, wherein the tray loading device is configured to support the tray and rotate back and forth at a constant speed. 3. The multi-disk according to claim 1, wherein the tray moving mechanism has a constant speed drive feed screw screwed into the slider, and the lead of the feed screw is formed to be small near both of the above positions. Player loading device. 4. Claims 1 and 2, wherein the slider is such that the balls on the left and right sides slide into long holes provided in the loading chassis, and the lower surface of the slider is guided by at least the upper surface of the loading chassis. Or a tray loading device for a multi-disc player according to 3.
