Tape & Ribbon Feed Mechanism
This mechanism consists of the tape feed motor, the gear train, and the roller holder ASSY.
Tape Feeding
The platen becomes the state pressing the tape and the ink ribbon (only the tape when mounting
the heat sensitive tape cassette) against the thermal head when printing, as described in
Subsection 2.1.2.
Also, the tape feed sub roller in the roller holder ASSY becomes the state pressing the tape (the
sandwiched laminated tape and the adhesive base tape when using a laminated tape cassette)
against the tape feed roller built in the tape cassette.
As the tape feed motor (stepping motor) rotates, the rotation is transmitted via the gear train to
the tape feed gear and the platen idle gear so that the platen idle gear, the tape feed roller and
the tape feed sub roller rotate at the same rotation speed. Accordingly, the sandwiched tape
and the ink ribbon will be advanced at the same speed. (When a laminated tape cassette is
mounted, the sandwiched laminated tape, the adhesive base tape, and the ink ribbon will be
advanced at the same speed.)
The feeding amount of the tape feed sub roller is slightly greater than that of the platen roller.
