  • Page 12: Chapter Ii Theory Of Operation

    CHAPTER II THEORY OF OPERATION 2.1 Main Mechanisms 2.1.1 Roller Holder ASSY Setting & Retracting Mechanism This mechanism consists of the roller release lever, roller holder release rod, and roller holder ASSY. The roller holder ASSY supports the platen roller and the tape feed sub roller so that they can move perpendicularly to the head ASSY and the tape feed roller, respectively, as well as rotating freely.

  • Page 13: Tape & Ribbon Feed Mechanism

    2.1.2 Tape & Ribbon Feed Mechanism This mechanism consists of the tape feed motor (DC motor), gear train, and roller holder ASSY. ■ Structure of Thermal Head When you load a tape cassette and close the cassette cover, the tape feed roller inside the cassette and the tape feed sub roller in the roller holder ASSY sandwich the tape (the laminate tape or adhesive tape when using laminated tape cassettes) inbetween, as described in Subsection 2.1.1.
  • Page 14 ■ Adhesive tape Feeding (only for laminated tape cassettes) A laminated tape cassette contains both a transparent laminate tape roll and a separate adhesive tape roll. When a transparent laminate tape and an adhesive tape pass through the contact point (between the tape feed roller and tape feed sub roller), they are then bonded together into a single, printed tape.

  • Page 15: Automatic Tape Cutter Mechanism

    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.

  • Page 16: Roller Holder Assy & Cassette Cover Interlocking Mechanism

    2.1.4 Roller Holder ASSY & Cassette Cover Interlocking Mechanism Closing the cassette cover pushes down the roller release lever and brings the top of the lever into the hooked section provided on the inside of the cassette cover. As described in Subsection 2.1.1 "Roller Holder ASSY Setting & Retracting Mechanism", the roller release lever shifts the roller holder release rod so that the roller holder ASSY is pressed towards the head ASSY side.

  • Page 20: 2 ] Cassette Sensor

    [ 2 ] Cassette Sensor The sensor circuit consists of a 7-switch cassette sensor (SW1 through SW7). Loading a tape cassette turns on some of those seven switches on the cassette sensor while keeping other switches off depending upon the ID encoding holes provided in the tape cassette currently loaded.
