Thus, the eccentric gear maintains the mechanism in
the state of tentative stop for “Playback” or “Recording”.
For “Fast-forwa:a’, or “Rewind”, the Corkscrew lever 'H)
works to push back the "FAST FWD, REWIND” knob to
the “Stop” position before stopping itself.
When the Automatic Cut-Off Switch is moved to “CUT
OFF" position, the Shut-Off lever (J) moves to the arrow-
mark direction to cut the power circuit, thereby depres-
sing the attached Micro Switch (K) to shut off the current.
