Platen Setting & Retracting Mechanism
This mechanism consists of the roller holder ASSY and the roller holder setting lever
(wedged lever) provided on the inside of the cassette cover.
The roller holder ASSY supports the platen so that the platen can move perpendicularly
to the thermal head and rotate freely.
Closing the cassette cover fits its roller holder setting lever into the slot between the roller
holder ASSY and the chassis's bent section. This pivots the roller holder ASSY around
the shaft provided on the chassis so as to press the roller holder ASSY against the
thermal head.
The platen is pressed perpendicularly against the thermal head with the tape sandwiched
inbetween under a uniform load by the platen spring. At the same time, the platen gear
becomes engaged with the drive gear of the gear train on the chassis (see Figure 2.1-3).
Opening the cassette cover pulls out its roller holder setting lever so that the roller holder
spring retracts the roller holder ASSY from the thermal head, providing you with enough
space to replace the tape cassette.
