FF operation is obtained by pressing and locking the FF
lever. As the FF lever is pressed, the switch arm tums to
turn ON the mute switch. The head base is moved
backward along the FF lever cam groove.
As the head base moves backward to release the pinch
roller from the capstan, the play idier gear is
simultaneously disengaged trom the reel gear. As the head
base moves backward, the FR arm centered by Section A
is put into rotation by the FR arm spring to engage with the
FWD side FR gear.
The FF lever is locked by the FR lock arm and performs
the FF operation. (Fig.17)
(3) REW operation

Similar to the case of FF operation, pressing the REW
lever causes the mute switch to be turned ON.
Simultaneously with release of the pinch roller from the
capstan, the play idler gear is disengaged from the ree!
gear. :
Section D of the REW lever presses a movable side of the
FR arm spring, thereby engaging the FR gear to the FR
gear on the REV side.
The REW lever is locked by the lock arm, performing the
REW operation. This operation is cancelled when Section
C is turned by the lever return spring. (Fig.18)
