ABSTRACT:
The sound-reproducing device for playing the record disc has a number of selection poles corresponding to the member of recorded grooves and a stylus force releasing wheel normally urged to a specific direction but which rotated by one of the selection poles to release stylus force on a pickup. The stylus force releasing wheel includes a locking arm confronting the back face of the selection pole in an advanced position for pushing the inclined face of the releasing wheel. Each of the selection poles has a jaw which catches the locking arm and prevents the selection pole when in an advanced position from retraction. A locking device locks the stylus force releasing wheel at the position to which the wheel has rotated. A record disc unit includes a turn table and a record face member disposed in a stacked but axially separable arrangement. A stopper pin is disposed on the record face member. A ratchet is interposed between the turn table and the record disc member so that the turn table alone can rotate and is urged and moved along the center pin by the ratchet by ratchet bight toward the bottom plate of chassis during the time when the stopper pin engages the selection pole and temporarily locks the record face member from rotation. The locking device includes a hook for locking the stylus force releasing wheel at a rotated position and an inclined face for unlocking the locked wheel.
