Fast Forward Operation
When solenoid F is activated, the drive arm is
moved to the right, and the drive gear on the arm
engages the idler gear, resulting in rotation of the
TU reel base as shown in Fig. 3-12 (the drive gear
being belt-driven by the capstan motor). At the
same time, the pin on the branch of the drive arm
pushes the brake plate up, thereby releasing the
reel brake.

Rewind Operation
When solenoid R is activated (see Fig. 3-18),
the drive arm is moved to the left, and the drive
gear on the arm engages the supply reel gear result-
ing in rotation of the supply reel base. At the same
time, the pin at the tip of the drive arm pushes the
brake plate up, thereby releasing the reel brake.
