Although the above-mentioned embodiment has been described with reference to an optical disc player using an optical pickup device, it goes without saying that the present invention can be applied to any player using a disc.

〔Effect of the invention〕

As described above, the present invention allows the diskette to be inserted and mounted perpendicularly to the cabinet on the rotating teagle that is rotated and driven perpendicular to the installation surface. The amount of movement of the disc holder can be reduced, and the disc player itself can be made smaller. Also, since the disk is mounted on the rotating Cheagle and removed from the NEI rotating Cheagle through the disk holder, there is a risk of damage to the disk. This ensures protection of the disk.

Furthermore, since the disc can be loaded and unloaded simply by inserting it into the disc insertion slot, the operation is simple and can be performed with one hand in particular. Furthermore, since the loading and ejecting operations 'f' for pulling the inserted disc into the player and mounting it on the rotating cheagle are performed by one drive motor, the configuration of the disc loading mechanism can be simplified. Furthermore, since the front panel and the disc holder are integrated and move together, the front panel serves as the entire lid, eliminating the need for a separate lid and a control mechanism for the lid, simplifying the configuration. can be converted into
