ABSTRACT:
A winding knob and a winding wheel for winding a drive spring are received in alignment around and along the center shaft and are capable of being coupled together in both directions of winding and their axial movement. A reverse slippage restraining post or plunger is disposed between the winding wheel and a record disc axially movable along the center shaft. The record disc is resiliently urged toward a pickup.
The reverse slippage restraining post or plunger engages a locking piece provided on the record disc when it is pushed forward by the winding wheel when the winding knob is pushed forward in its first winding, while it is pushed back when the record disc is moved away from the record disc by the depression of a starting post, and is released from the engagement with the locking piece to permit rotation of the record disc when the record disc reverts back to its undepressed position when the depression on the start post is released.
In order to stop any idling rotation of the record disc immediately after the completion of one sound reproduction of the record disc, a rotatable pawl member and a fixed pawl member are disposed, respectively, on the record disc or a turn table and the casing.
