Akai 1700 Service Manual

FAST-FORWARD MECHANISM
Turn the FAST FWD-REWIND knob (A) to “FAST
FWD” position, and he cam (B) under the knob pushes up
the Lever (C). The Idler (D) moves into the space between
the 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 the Supply Reel Spindle (G), thereby allowing
fast winding of the tape onto the take-up reel.

position, and the cam (B) under the knob pushes the Levey
(C) up. The Idler (D) moves into the space between the up-

Intermediate Pulley (F} to transmit the high-speed rotation
of the motor through the intermediate pulley to the Supply
Reel Spindle (G). At the same time, Brake Rollers (H) and (I)
come off the reel spindle to free the take-up reel spindle (J),
thereby rewinding the tape into the supply reel at a fast
speed,
