ABSTRACT:
A movable blade unit is fixed to a cutter release lever. The cutter release lever is attached to an upper frame by a cutter supporting point shaft so as to freely oscillate. A latch lever holding the upper frame at a closed position and a cutter lock lever locking the cutter release lever are integrated, and are coupled by an opening and closing lever. If the opening and closing lever is pushed down, the cutter lock lever cancels the lock of the cutter release lever while keeping a state in which the latch lever latches the upper frame. Accordingly, in the movable blade unit, a driving force transmission path between the movable blade unit and a cutter driving motor is disconnected, and a movable blade is returned to a home position by a return spring.
