2.1.3 Tape & Ribbon Feed Mechanism
This mechanism consists of a DC motor, gear train, and roller holder ASSY.
(1) Tape Feeding
As the tape feed motor (DC motor) rotates, the rotation is transmitted via the gear train to
the platen idle gear (which rotates both the platen gear) and the tape idle gear (which
rotates the tape feed sub roller).
Accordingly, the sandwiched tape and ink ribbon will be advanced. (When a laminated tape
cassette is mounted, the sandwiched laminate tape, adhesive base tape, and ink ribbon will
be advanced together.)
The feeding amount of the platen is slightly less than that of the tape feed sub roller.
