PURPOSE:To miniaturize the entire device by elevating/descending a disc reproducing mechanism along a cam of a rotation body forming a cam requiring one rotation or over from one end until reaching the other end to attain the elevating/descending operation by a small-sized drive source. CONSTITUTION:The cam 20 requiring one revolution or over of a gear 19 is formed to a cam gear 19 from one end until reaching the other end and the cam 20 applies elevating/descending operation of a disc reproducing mechanism 13. Thus, even when the diameter is small as the gear 19, sufficient torque is generated and the miniaturization of the entire disc reproducing device is progressed effectively. |
