6. AUTOMATIC STOP MECHANISM

When the tape is threaded on pin (B), if the tape is
accidentally broken or comes to the end, Automatic
Stop Lever (A) drops to its original position.

When the tape is broken or comes to the end, Plate
Spring (C), located below the Automatic Stop Lever,
depresses a projected pin on Eccentric Gear (D).
Eccentric Gear (D) gears into Flywheel (E) to begin
rotation of the Eccentric Gear, This rotating action
operates Lever (L), which is connected to the base of the
Eccentric Gear, and Pushes up Instant Stop Lever (C).
When instant Stop Lever (G) is lifted, Shut-Off Lever (J)
contacts Micro Switch (K) and the current supply is cm
off. Thus, automatic stop control is provided in
Recording and Playback modes.

in Fast Forward and Rewind modes, the same operation
takes place except that Lever (H) works to push back
the FF, Rewind Shaft to Stop" position.
