<p>PURPOSE:To perform auto-play operation surely without malfunctions with a simple constitution, by providing a locking mechanism, which releases the lock by an operating piece for tape constant-speed running in the operation position, and a holding part which holds an operating piece for tape high-speed running in the operation position until a releasing part of the first rotating material is disengaged from a detecting member. CONSTITUTION:When a PLAY operator 12c and an REW operator 12a are locked together in the operation position, a rewinding/reproducing (review) state is set. When a tape runs out in this state, an ASO lever 54 is turned, and the REW operator 12a is held in the lock position. A gear 47 is rotated; and when its releasing piece 472 is disengaged from a pin 531 of an ASO driving lever 53, the ASO lever 54 is turned counterclockwise and is returned to a position where it is brought into contact with an engaging piece 552 of a switch slider 55. Therefore, holding of the REW operator 12a due to an arm part 544 in the operation position is released, and the REW operator 12a is returned to the non-operation position, and the PLAY operator 12c is locked in the operation position still, and a reproducing state is set, and the auto-play operation is performed. Since the REW operator 12a is held in the operation position until the releasing piece 472 of the gear 47 is disengaged from the pin 531 of the lever 53, malfunctions are prevented surely.</p> |
