2.1.5 Cutter Safety Lock Mechanism
When the cassette cover is opened and no tape cassette is loaded, the roller holder
ASSY is retracted from the thermal head with the roller holder release spring (as
described in Section 2.1.2). In this retracted position, the cutter lever stopper of the
roller holder ASSY blocks the end of the cutter lever, preventing the cutter blade from
getting driven for safety, as shown below.
Closing the cassette cover releases the cutter safety lock mechanism.
If you close the cassette cover, the roller holder ASSY pivots towards the thermal
head so that the cutter lever stopper does not interfere with the cutter lever.
