  • Page 14: Theory Of Mechanism Operation

    THEORY OF MECHANISM OPERATION 2.1.1 Printing Mechanism (1) Construction of thermal head This machine uses thermal transfer printing. The thermal head contains 384 heating elements vertically arranged. The size of one heating element is 0.08 mm wide by 0.0545 mm high, as shown in Fig. 2.1-1. Fig.
  • Page 15 [For non-laminated thermal film tape cassettes] If the selected heating element(s) generates heat, the thermal film tape develops itself to produce a dot on the tape. The tape is advanced and the next printing cycle is repeated, thus forming a character and graphics on the tape.

  • Page 16: Roller Holder Assy Setting And Retracting Mechanism

    2.1.2 Roller Holder Assy Setting and Retracting Mechanism This mechanism consists of the release cam, roller release rod, and roller holder/head assy. The roller holder assy incorporates the platen holder and the sub roller holder. These holders support the platen and the tape feed sub roller so that they can move perpendicularly to the thermal head and the tape feed roller, respectively.

  • Page 17: Regular Tape And Ribbon Feed Mechanism

    2.1.3 Regular Tape and Ribbon Feed Mechanism This mechanism consists of the tape feed motor, the gear train, and the roller holder assy. (1) Regular Tape Feeding When you load a tape cassette and close the cassette cover, the platen and the thermal head sandwich the tape and ink ribbon (only the tape when using non-laminated thermal film tape cassettes or stamp tape cassettes) inbetween.
  • Page 18 (2) Adhesive Base Tape Feeding (only for laminated tape cassettes) A laminated tape cassette contains both a transparent laminated tape roll and a separate adhesive base tape roll. When a transparent laminated 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 19: Tape Automatic Full Cutter Mechanism

    2.1.4 Tape Automatic Full Cutter Mechanism The tape automatic full cutter mechanism consists of a stationary blade and a movable blade driven by the full cutter motor. Upon completion of printing and tape feeding, the CPU activates the full cutter motor (DC motor) whose clockwise rotation is transmitted to the cutter helical gear.

  • Page 20: Tape Automatic Half Cutter Mechanism

    2.1.5 Tape Automatic Half Cutter Mechanism The tape automatic half cutter mechanism consists of a stationary plate and a half cutter holder (equipped with a cutter blade) which is operated by the half cutter motor.
