2.1.4 Tape & Ribbon Feed Mechanism
This mechanism consists of a DC motor, gear train, and roller holder ASSY.
■
Tape Feeding
As the DC motor rotates, the rotation is transmitted via the gear train to the platen idle
gear (which rotates the platen roller gear) and tape idle gear (which rotate the tape
feed roller and its sub roller at the same rotation speed).
Accordingly, the sandwiched tape and ink ribbon will be advanced at the constant
speed. (When a laminate tape cassette is mounted, the sandwiched laminate tape,
ink ribbon and adhesive base tape will be advanced together).
■
Adhesive Base Tape Feeding (only for laminate tape cassettes)
A laminate tape cassette contains both a transparent laminate tape roll and a
separate adhesive base tape roll.
When a transparent laminate tape and 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. The ink printed on the laminate tape is, therefore,
sealed up with the adhesive base tape.
