4. FAST-FORWARD MECHANISM
Turning the FAST FWD-REWIND LEVER (A) to
“FAST FWD” position, causes cam (B) under the knob
to push up Lever (C). Idler (D) moves into the space
between Plastic Roller (F) above the Take-Up Reel
Spindle and the upper part of the rotating motor drive
bushing to transmit the motor rotation to the take-up
reel spindle. At the same time, Brake Rollers (H) and (I)
come off the reel spindle to free Supply Reel Spindles
(G) and (F), thereby allowing fast winding of the tape
onto the take-up reel.
(See figure 3)

knob
(A)
to
“REWIND” position, causes cam (B) under the knob to
push up Lever (C). Idler (D) moves into the space
between the upper part of the rotating Motor drive
bushing (E) and the Intermediate Pulley (F) to transmit
the high-speed rotation of the motor through the
intermediate pulley to Supply Reel Spindle (G). At the
same time, Brake Rollers (H) and (I) come off the reel
spindle to free take-up reel spindles (J) and (G), thereby
rewinding the tape onto the supply reel at a fast speed.
(See figure 4)
6. STOP CONTROL
