PURPOSE:To prevent the flaw of a disk as well as noises generated by the open/ close of a cover by fitting the disk to a rotary shaft of a turntable to secure a play mode after putting the disk on an upwardly sloping disk stage and then closing the cover. CONSTITUTION:When a knob 7 is moved up to load/unload a disk 1, a cover 5 is turned upward as shown by an arrow head. At the same time, a disk stage 8 is turned in the opposite direction to the cover 5 to secure a disk loading/unloading position sloping upward and obliquely. In this case, the contact of a switch 15 is opened to stop th revolution of a turntable 2 as well as actions of other devices. Under such conditions, the disk 1 can be loaded to and unloaded from the stage 8. When a play mode is desired again, the cover 5 is closed to set automatically the disk 1 at a prescribed position on the table 2. This prevents the flaw generated when the disk 1 is loaded and unloaded. Furthermore no effect is produced at all from vibration caused by opening/closing of the cover 5 since a play mode is possible only when the cover 5 is completely closed. |
