Abstract

PROBLEM TO BE SOLVED: To prevent the erroneous insertion of a disk without making the height of a door closing an optical disk inserting port higher by providing a protrusion preventing the optical disk from being inserted from the gap between the door and the optical disk inserting port when the door opening and closing the optical disk inserting port is closed. SOLUTION: When a disk 8 is to be inserted in the optical disk inserting port, a rubber roller arm 4 is rotated in a clockwise direction around an axis 7 and the disk 8 is held in between a rubber roller 5 and a disk guide 6 to be fed on a turntable 1a. When a clamp holder 2 is lowered and the disk 8 is clamped in between a clamper 3 and the turntable 1a, the rubber roller arm 4 is rotated in a counterclockwise direction and the disk inserting port is closed by a door 4a at this time. A protrusion 4b is provided at the upper part of the door 4a toward the outside. Thus, even when the tip of a second disk is directed toward the top of the door, the tip of the disk is caught by the protrusion 4b and the disk can not be inserted under the disk guide 6. Thus, the erroneous insertion of the disk is prevented.

After that, the clamper holder 2 is lowered to lower the clamper 3 on the turntable 1a, whereby the turntable 1a attracts the clamper 3 by magnetic force and the disk 8 is clamped. In addition, the lock of the floating chassis is released, and the rubber roller arm 4
Is rotated counterclockwise, the rubber roller 5 is separated from the disk 8. In this way, the floating chassis shown in FIG.
Playback of the disc is performed. At this time, the door 4a covers the disc insertion port. The operation opposite to the above is performed when the disc is ejected after the reproduction is completed.
