ATTACHING/DETATCHING DEVICE OF DISC

摘要

PURPOSE:To attach/detach a disc easily and to prevent the recording surface of the disc from dirtying, by opening/closing a disc holder by a driving motor and interlocking an elevation arm with a slider to ascend/descend the disc. CONSTITUTION:Projected sliding surface 36 are slided while being contacted with the inwalls of a back plate 10 and a disc holder 11 and a reversed V- shaped disc receiving part 38 to receive the disc is attached to the other end. Each elevation arm 32 is arranged between a slider 35 and the back plate 10. Coupling boards 41 and rotary arms are turned around supporting shafts 44 by the rotation of a driving motor and the sliders 35 are ascended. Accompanied with the elevation of the sliders 35, the elevation arms 32 are turned, sliding shafts 34 are slided along the guiding holes of the sliders 35 and the disc receiving part 38 is elevated up to a position where the center hole of the disc is exposed while putting the disc on it.
