Tape & Ribbon Feed Mechanism
This mechanism consists of the tape feed motor, the gear train, and the roller holder ASSY.
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 adhesive base laminated tape) 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.
