ABSTRACT:
A winding knob and a winding wheel are supported around a center shaft and are rotatable together in the direction of winding and are also axially movable together without causing axial movement of the center shaft by pushing ahead the winding knob. Between a record disc being urged toward a pickup and movable along the center shaft and the winding wheel, there is provided a slippage preventing post which is placed into engagement with a retaining piece provided on the reverse face of the record by operator's winding motion while depressing the knob but is released from such engagement by the operator's subsequent depression of a starting post and the movement of the record disc away from the pickup. When the record disc returns to its initial position by the operator's releasing of depression, the slippage preventing post moves out of engagement with the locking piece. The starting post is mechanically coupled to a driving source for rotating the record disc so as to play the sounds recorded therein and also serves as an output shaft to other devices outside of the sound reproducing device. In order to stop the record disc concurrently with or immediately after the completion of sound reproduction and also to prevent undesirable turning of the record disc during a winding operation a rotatable pawl member and a stopper pawl member are disposed on the record disc and casing, respectively. By virture of this construction, a sound reproducing device of this type can be operated exactly with a very simplified construction which also enables its driving mechanism to drive other devices disposed outside of the sound reproducing device.
