Roller Holder ASSY Setting & Retracting Mechanism
This mechanism consists of the release lever, roller release rod, and roller holder/head assy.
The roller holder assy incorporates the platen holder and the sub roller holder. These holders
support the platen and the tape feed sub roller so that they can move perpendicularly to the
thermal head and the tape feed roller, respectively.
The platen is pressed perpendicularly against the thermal head under a uniform load regardless of
the thickness of the tape, so that the tape is fed.
Closing the cassette cover pushes down the release lever which moves the roller release rod to
the left (when viewed from the front of the machine). This pivots the roller holder assy around the
shaft secured on the thermal head assy so as to press the roller holder assy against the thermal
head.
The platen is pressed perpendicularly against the thermal head with the tape and ink ribbon (only
the tape when using AV labels cassettes or stamp tape cassettes) sandwiched inbetween under a
uniform load by the platen spring.
At the same time, the platen gear becomes engaged with the platen idle gear.
Also, the tape feed sub roller is pressed perpendicularly against the tape feed roller built in the
tape cassette with the tape (and base paper when using laminated tape cassettes or stamp tape
cassettes) sandwiched inbetween under a uniform load by the sub roller holder springs. At the
same time, the sub roller gear becomes engaged with the tape feed roller.
Opening the cassette cover causes the release lever spring to slide the roller release rod in the
direction of the arrow. This retracts the roller holder assy from the thermal head, providing you
with enough space to replace the tape cassette.
