Claims

[Scope of utility model registration request]

A loading table configured to be horizontally movable in and out from a front opening provided in the player body, a tray attached to the loading table so as to be vertically movable, and a turntable provided in the player body. and a clamper arranged above the turntable and configured to be able to move up and down in the vertical direction, and with the disc placed horizontally on the tray,
The loading table is pulled horizontally into the player body to move the disc to a position above the turntable, and then the tray is lowered to mount the disc onto the turntable and the clamper is lowered. In a disc player configured to press and fix the disc onto a turntable using the clamper, and in this state rotate the disc on the turntable to perform desired recording or playback, the tray is lowered. When a disc is mounted on the turntable and the disc rides on the center guide of the turntable due to misalignment of the disc with respect to the center of the turntable, the downward stroke of the clamper is limited. In addition, a sensor is provided to determine that the downward stroke of the clamper has been restricted, and a sensor is provided to determine whether the downward stroke of the clamper has been restricted, and to detect a disk installation error and remove the disk from the tray and loading table. A disc player characterized in that the disc player is configured to be able to be pulled back out of the player body.
