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.
Claims13
A cutter apparatus comprising:
- an upper frame attached to a base frame so as to be openable and closeable;
- a movable blade unit provided in said upper frame;
- and
- a driving mechanism for transmitting a driving force from a driving source to said movable blade unit,
- wherein said movable blade unit is attached to said upper frame so as to be movable, and
- wherein the cutter apparatus is provided with a cutter lock mechanism which presses a roller attached to a leading end of a cutter release lever coupling said movable blade unit to said driving mechanism by locking said movable blade unit in a state in which said upper frame is closed, and
- upon transition of said upper frame from the closed to open state, uncoupling said movable blade unit and said driving mechanism by releasing pressure from the roller attached to a leading end of a cutter release lever allowing a moveable blade of said movable blade unit to rotate away from a fixed blade and detach said driving mechanism from a driving force so as to allow said moveable blade unit to move.
