ABSTRACT:
A recorded disk playback apparatus in accordance with the present invention includes a sub-chassis whose one end is supported as turnable with the main chassis that is housed in the main frame, carriage which is freely movable on the sub-chassis to feed the pick-up head in the radial direction of the recorded disk, a turn table which is placed on the sub-chassis to have the recorded disk placed on it, a slide table which transports the recorded disk to a position which coincides with the center of the rotatable turn table, a disk clamper which is fixed rotatably to the main chassis, an adjusting mechanism which moves the carriage, as well as moves the sub-chassis upward/downward, a driving motor which, by the driving of the adjusting mechanism, serves commonly for the feeding drive of the pick-up head and the turning drive of the sub-chassis, and a locking/unlocking mechanism which locks/unlocks the slide table in association with the operation of the adjusting mechanism. The engagement/disengagement of the disk clamper with respect to the recorded disk which is placed on the turn table is controlled by the raising/lowering drive of the sub-chassis.
