3.1.3 Sensor PCB
This PCB holds two mechanical sensors; a cassette sensor that detects the tape width
and ink ribbon type in a tape cassette loaded and a cover open sensor that detects the
opened/closed state of the cassette cover.
3.1.4 Tape End Sensor PCB
The tape end sensor uses a photo-interrupter to detect a zebra pattern provided at the
end of tape.
3.1.5 Sub PCB
The sub PCB holds the FEED/CUT switch (FEED/CUT button) and the ON/OFF switch
(ON/OFF button) with the lamp (green and red LEDs).
3.1.6 Cutter Sensor
The cutter sensor is a mechanical switch which detects the home position of the cutter.
3.1.7 Cutter Motor
The cutter motor is a DC motor which drives the cutter to cut the tape. This motor
operates on 12V.
3.1.8 Tape Feed Motor
The tape feed motor is a Ø30 stepping motor which drives the tape feeding mechanism
to feed both the tape and ribbon. This motor operates on 12V.
3.1.9 Thermal Head
The thermal head is a driver-integrated thick-film head having 128 heating element
aligned in 180 dpi. The drive voltage is 12V.
