In order to feed the disc 14 to a predetermined loading position and to eject the disc 14 after playback, a drive 1-1-roller 16 and a guide roller 18 are provided immediately after the disc 1Φ entrance 12a. a5, the guide roller 18 is supported by a swinging arm 20, and the disk 14 can be held between both rollers 16 and 18 with a predetermined pressure.

FIG. 1 shows a case in which the disk 14 can be loaded.
In this state, the disk 1/l is in the disk rotation II! The disk holder 24 located at position 11 corresponding to Ill 22 and located on the F side of the disk 14 is located at the disk pushing up position (C/ii), and the descending device 26 pushes the disk holder 24 up. By pushing upward, the center hole of the disk 1/l IJ is fitted into the disk rotating shaft 22 at a predetermined position 115'.

A characteristic feature of the present invention is that when loading the disk shown in FIG. In particular, the brush 28 is made up of a plurality of soft bristles that extend from above and below the disc holder 12a, and can easily remove dust from the disc surface without causing any damage. It's loud.
