    2.1.2 Platen Roller, (Tape Feed) Sub Roller Setting & Retracting Mechanism This mechanism consists of the holder cam (cassette cover ASSY) and the roller holder ASSY. The roller holder ASSY supports the platen roller and the sub roller so that : Ÿ...

  • Page 18: Tape & Ribbon Feed Mechanism

    2.1.3 Tape & Ribbon Feed Mechanism This mechanism consists of a DC motor, gear train, and roller holder ASSY. Tape Feeding As the tape feed motor (DC motor) rotates, the rotation is transmitted via the gear train to the platen idle gear (which rotates both the platen gear) and the tape idle gear (which rotates the tape feed sub roller).
  • Page 19 Adhesive Base Tape Feeding (only for laminated tape cassettes) A laminated tape cassette contains both a transparent laminate tape roll and a separate adhesive base tape roll. When a transparent laminate tape and an adhesive base 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 20: Tape Cutter Mechanism

    2.1.4 Tape Cutter Mechanism The tape cut unit consists from the cutter case ASSY and the board. Tape that finished printing is fed out from the tape cassette and stops at a point passed between the cutter case ASSY and the board. When the cutter lever is pushed at this point, then, the cutter case ASSY (cutter blade) is operated to cut tape.

  • Page 21: Cutter Safety Lock Mechanism

    2.1.5 Cutter Safety Lock Mechanism When the cassette cover ASSY is opened and no tape cassette is loaded, the roller holder ASSY is retracted from the thermal head with the roller holder release spring (as described in Subsection 2.1.2). In this retracted position, the cutter lever stopper of the roller holder ASSY blocks the end of the cutter lever, preventing the cutter blade from coming out of the cutter case ASSY for safety, as shown below.

  • Page 22: Interlock Mechanism Of The Roller Holder

    2.1.6 Interlock Mechanism of the Roller Holder When the cassette case ASSY is opened, then the holder cam attached at back side of cassette cover is released from surface A. Following to that, the roller holder ASSY is retracted from the thermal head side with tension of the roller release spring. When the cassette cover ASSY is closed, then the holder cam located at backside pushes the thermal head at roller holder ASSY by pressing A surface of the roller holder ASSY.
