ーデイング装置。[Scope of Claim for Utility Model Registration] A main chassis that holds a loading chassis on which a turntable is disposed, a disk tray that enters into the main chassis, and a disk tray that is disposed on the main chassis and moves the disk tray in its advancing and retreating direction. In the loading device for a disk player, the disk player is equipped with a loading motor that moves the disk along the disk tray, and a permanent magnet is disposed at an inner end of the disk tray along the advancing and retracting direction, and the permanent magnet is disposed at an inner end of the main chassis. A coil is provided that generates an induced electromotive force when the motor approaches the loading motor, and an induced electromotive force detection circuit is provided to detect the generation of the induced electromotive force in this coil, and a normal voltage is applied to the loading motor. Switching for switching between a normal voltage supply power supply, a low voltage supply power supply that applies a voltage lower than the normal voltage to the loading motor, and a power supply connected to the loading motor based on the output from the induced electromotive force detection circuit. 1. A loading device for a disk player, comprising an approach speed control means comprising means.
