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.
Also, the tape feed sub roller in the roller holder assy and the tape feed roller
inside the tape cassette sandwich the tape (and base paper when using
laminated tape cassettes or stamp tape cassettes) inbetween, as described in
Subsection 2.1.2.
As the tape feed motor (stepping motor) rotates, the rotation is transmitted via
the gear train to the platen idle gear (which rotates the platen gear) and the
tape feed gear (which rotates the tape feed roller and the tape feed sub roller
at the same rotation speed).
Accordingly, the sandwiched tape and ink ribbon will be advanced. (When a
laminated tape cassette is mounted, the sandwiched laminated tape, adhesive
base tape, and ink ribbon will be advanced together.)
The feeding amount of the tape feed sub roller is slightly greater than that of
the platen roller.
