2.1.3 Automatic Tape Cutter Mechanism
This mechanism consists of the cutter fixed blade and the cutter movable blade driven
by the cutter motor.
Upon completion of printing and tape feeding, the CPU activates the cutter motor (DC
motor) whose clockwise rotation is transmitted via the cutter double gears to the cutter
moving gear.
As the cutter moving gear rotates counterclockwise, its boss "X" (which is fitted in the
opening of the cutter movable blade) moves the cutter movable blade on the shaft "Y" to
the direction to the arrow as show in the figure below. Consequently, the cutter cuts the
printed tape routing through the cutter movable and fixed blades, just like a scissors.
After that, the CPU keeps the cutter motor on. When the cutter 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.
