2.1.4
Automatic Tape Cutter Mechanism
The cutter ASSY consists of a stationary blade and a movable blade driven by the cutter motor.
Upon completion of printing and tape feeding, the CPU activates the cutter motor whose clockwise
rotation is transmitted via the idle gears to the cutter moving gear.
As the cutter moving gear rotates counterclockwise, its boss "X" (which is fitted in the opening of
the movable blade) actuates the movable blade to pivot it around shaft "Y." Consequently, the
cutter cuts the printed tape routing through the movable and stationary blades, just like a scissors.
After that, the CPU keeps the cutter motor on. When the movable blade comes back to the home
position, its end "Z" activates the cutter sensor actuator which presses the cutter sensor. The
moment the CPU receives the sensor signal, it stops the cutter motor.
