Tape Automatic Half Cutter Mechanism
The tape automatic half cutter mechanism consists of the fixed plate and the half cutter holder
(the cutter blade is attached) driven by the half cutter motor.
This mechanism is applied only to the laminated tape.
After tape printing and feeding, the CPU directs to rotate the half cutter motor (DC motor)
counterclockwise, and the drive power is transmitted to the half rock gear via the clutch gear and
three idle gears.
Then, the half rock gear rotates counterclockwise, and the groove “D” of the gear moves the half
cutter holder around the shaft “E” because the boss of the half cutter holder is engaged with that
groove.
The fixed plate has the step equivalent to the thickness of the separator of the laminated tape,
against which the half cut holder (the cutter blade is attached) presses the laminated tape for
half cutting.
* Half cutting means the cutting motion to cut only the tape leaving the separator un-cut.
Then, the CPU directs to rotate the half cutter motor in reverse, by which the half cutter holder is
returned to the home position, the half cutter sensor on the half frame is pressed by the “F” part
of half rock gear and the motor is stopped at the moment when the CPU receives the signal
from the sensor.
