<p>PURPOSE:To eliminate the need of a return energizing means and to simplify the constitution by interposing a freely rotatable shut-off transfer lever between a slide member for detaining an operating lever to an operating stage, and a shut-off member for pressing the slide member at the time of shut-off and releasing the detention against the operating lever, and energizing said lever in one direction. CONSTITUTION:In a reproducing mode, when a switching lack tooth gear 53 rotates from a reverse position to a normal position, namely, in the direction as indicated with an arrow C, an operating part to be pressed 74b is pressed by an eccentric cam part 54 and turns in the direction U, a shut-off lever 74 turns thereby, and by a pressure operating part 74c of the other end side, a lock plate 28 is moved in the direction as indicated with an arrow D' through a piece to be pressed 75a of a shut-off transfer lever 75. In such a way, when the lock plate 28 has moved, a claw part 24a which is pressed and a detaining claw part 28i are engaged in a forward moving position, the lock in the forward moving position of a reproducing lever 24 which has been locked by the lock plate 28 is released, and a reproducing or recording operation is stopped.</p> |
