PURPOSE:To make the lock releasing plunger needless to simplify the mechanism and facilitate the operation, by operating the plunger to lock the operation material and by using the plunger, which operates another operation material, for the purpose of releasing this lock thereafter. CONSTITUTION:In the reproducing mechanism, reproducing plunger 1 is operated, and driving lever 7 is sucked, and operation lever 20 is slided against spring 29. Lock pawl 20a is held in the lock state, and reproducing operation lever 35 is interlocked and operated also. Lock lever 16 moves to the left, and driving levers 8 and 9 are turned counterclockwise by contact pieces 18 and 19. For releasing the reproducing mode, plunger 2 or 3 is operated. When plunger 2 is operated, release lever 39 is slided, and lock lever 16 moves to the left to release the lock of operation lever 20, and reproducing operation lever 35 is returned to the nonoperation position also. |
