ABSTRACT:
An intermittent gear wheel lock mechanism includes major engaging portions and secondary engaging portions formed on one surface of an intermittent gear wheel and spaced by a predetermined distance. When an unlock lever is inserted, and a lock member is detached from the major engaging portion, the lock member is moved to the movement path of the secondary engaging portion while the unlock member remains in the inserted position, so that the lock member engages the secondary engaging portion which reaches there as the intermittent gear wheel rotates, and locks the intermittent gear wheel unrotatable. When the unlock lever returns to its original position, the lock member moves from the secondary engaging portion to the movement path of the major engaging portion and engages same to lock the intermittent gear wheel unrotatable.
