2.1.3
Tape & Ribbon Feed Mechanism
This mechanism consists of a DC motor, gear train, and roller holder ASSY.
(1)
Tape Feeding
When you load a tape cassette and close the cassette cover, the tape feed roller inside the
cassette and the tape feed sub roller in the roller holder ASSY sandwich the tape (the
laminate tape and adhesive base tape when using laminated tape cassettes) inbetween, as
described in Subsection 2.1.2.
As the DC motor rotates, the rotation is transmitted via the gear train to the tape idle gear
(which rotates the tape feed sub roller gear) and the platen idle gear (which rotates the tape
feed platen gear). Accordingly, the sandwiched tape and ink ribbon will be advanced.
(When a laminated tape cassette is mounted, the sandwiched laminate tape and adhesive
base tape and ink ribbon will be advanced together.)
The feeding amount of the platen is slighty less than that of the tape feed sub roller.
