Claims

[Claims for Utility Model Registration] 1. A signal reproducing unit which is moved by a drive gear for loading or unloading a tray between a disk ejecting position and a reproducing position and is movable up and down to a chassis. The disc is configured such that the turntable is moved upward so that it comes into pressure contact with the clamper after the tray is stopped during loading by a cam part of the slider that is linked to the drive gear, and is moved downward before the tray is moved during unloading. A disk loading device characterized in that a slider lock mechanism locks a slider in a signal reproducing unit lowered position except when the tray is in a playback position, and a tray lock mechanism locks the tray in the playback position. Device. 2. The slider lock mechanism includes a ring-shaped wall that is provided concentrically to the drive gear and has a notch, a protrusion that is provided on the slider to contact the inner peripheral surface of this ring-shaped wall, and a guide hole;
The tray lock mechanism consists of a guide pin provided to abut on the inner end of the guide hole, and a tray lock mechanism that engages with an arc-shaped stopper provided concentrically with the drive gear and a stopper provided on the tray. 2. The disk loading device according to claim 1, wherein the disk loading device comprises a protrusion having a notch.
