2. Auto-Stop
When tape transport stops, the counter pulley driven by
a round belt passing over the reel base, and the 12-polar
ring magnet connected to the counter pulley, also stop.
This is detected by the Hall IC, resulting in the activa-
tion of the auto-stop circuit. The solenoid plunger is
consequently pulled in, thereby moving the stop plate,
and releasing the depressed keys.
3. Memory Rewind
When the counter returns to 999 during rewind mode,
and the solenoid thereby activated, a pin inserted in
the core of the solenoid acts against the stop plat, there-
by releasing the depressed key.
The position of this pin is determined by the timer lever.
Consequently, only the stop plate is moved.
Although the timer lever is also coupled to the pause
key, it will not be moved unless the play key is also
depressed. The timer lever is held in check by the
selector lever.
4. Timer Start
When the record key (and/or play key) and pause key
are pressed, the selector lever is moved forwards. And
since the timer lever is coupled to the pause key, the pin
is moved away from the stop plate, but is in contact
with the operation plate. When the power supply is
turned on, and the solenoid activated, the operation
plate is moved across to the lock plate (which holds the
pause key in the pause position), thereby releasing the
lock.
