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 spring (as described in
Subsection 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 coming out of
the cutter unit for safety, as shown below.
Closing the cassette cover or loading a tape cassette releases the cutter safety lock
mechanism as follows.
Closing the cassette cover pivots the roller holder ASSY towards the thermal head so
that the cutter lever stopper does not interfere with the cutter lever.
When a tape cassette is loaded, its outer edge pushes the tab of the roller holder ASSY
to pivot the roller holder ASSY towards the thermal head so that the cutter lever stopper
does not interfere with the cutter lever.
