T slider assembly
T brake (soft brake)
S brake (OFF)
Tension lever (OFF)
Pinch assembly (OFF)
No. 9 guide lever (OFF)
[4] FF/REW mode
(1) When the [REW] button is pressed in playback standby mode, the mode enters the FF/REW mode.
(2) IC601 controls Capstan Motor Drive IC and makes the loading motor rotate in the forward direction.
The loading motor stops when the cam position reaches the position VI, VII (FF/REW mode).
The mechanism status is as follows :
1) The pinch roller is OFF.
2) The No. 9 guide is once loaded but immediately returned.
3) The tension post is moved to the reel disc side. That is, the band brake is released from the ON status and
the back tension is released.
4) The clutch holder assembly is in the direct status and the capstan driving force is directly transmitted to the
reel disc.
5) Brakes for the reel discs are as follows :
Œ
VI position FF/REW 1 mode (S Brake : soft brake, T Brake : off)
´
VII position FF/REW 2 mode (S Brake : off, T Brake : soft brake)
(3) IC601 makes the capstan motor rotate in the forward direction and the idle gear transmits the rotation to the
S/T reel discs to take up the tape.
[5] FF/REW to STOP mode
(1) When the [STOP] button is pressed in the REW mode, the mechanism enters the playback standby mode.
(2) IC601 makes the loading motor rotate in the reverse direction and stops at the position V.
With this mode shift, the mechanism actuates S, T main brakes to stop the tape. Then, the capstan motor also
stops by braking force 70ms after detecting “e” position.
(3) IC601 makes the loading motor rotate in the reverse direction again and stops the loading motor when the
cam slider reaches the position IV (playback mode), thus setting the playback standby mode.
