Disc players that can commonly use cIL discs are known. By the way, with such a tray structure, when using a 1.2CI11 disk, a large tray comes out from the main body in the same way as when placing a 30c1n disk, making it difficult to operate when loading the disk, especially when using a player. If you set the 12-inch disc in a position other than its intended position, such as when the disc is placed in a high position, not only will it not be possible to move it to the playback position within the main unit, but it may also damage the disc. Furthermore, since a tray of the same size as a large-diameter disk must be used to place a small-diameter disk, it is disadvantageous in terms of power consumption. Therefore, we devised a playback device that has a special tray for loading only 12-day discs. FIG. 9 is a perspective view showing its general shape. After the door member 103 is opened, 12 cI
