(1) When the [PLAY] button is pressed in the stop mode, the mechanism enters the playback mode.
(2) IC601 controls cylinder motor drive IC and rotates the cylinder motor.
(3) IC601 controls Capstan Motor Drive IC to rotate the loading motor in the reverse direction and stops the motor
when the cam slider reaches the position IV (playback mode). (When operating from the playback standby
mode, the cam slider has been already on the position IV.) The mechanism works as follows :
1) The pinch roller moves toward the capstan side and press fits the capstan.
2) The No.9 guide is loaded once and then returned immediately.
3) The tension post touches the tape, the band braking force is applied, and the tension servo mechanism
works.
4) The clutch holder assembly enters clutched condition.
5) S,T brakes are released.
(4) IC601 makes the capstan rotate in the forward direction and feeds the tape. The idle gear transmits the
rotation to the T reel disc and the reel disc takes up the tape at a constant torque by the clutch mechanism.
(5) IC601 controls the video circuit and switches the playback screen.
(6) The recording speed data identified by IC601 is displayed in the Led module.
