[1] Cassette loading & Tape loading mode
<Cassette loading>
(1) The FL cam gear is in the Cassette unloading (position I)position, and the cassette holder is in the out status
(start sensor ON). Under this condition, each motor is stopped.
(2) Status of the mechanism is as follows.
1) S.T guide rollers, tension post, No.9 guide are in unloading status and housed in the reel disc side.
2) S brake is released and T brake is in soft brake status.
3) The clutch holder assembly is in clutched status and idle lever assembly is enabled to be engaged with both
S and T reel discs.
(3) When a cassette is inserted, the lock lever of cassette holder is released from the stopper, the cassette holder
moves, the FL arm lever rotates, and the FL Drive Slider slides, thereby closing the start sensor.
(4) IC601 controls Capstan Motor Drive IC to rotate the loading motor in forward direction, and move the cassette
holder. At the same time, the capstan motor rotates in the reverse direction and moves the cassette
down (vertical motion) while rotating the S reel disc.
(5) The cassette lid opens when the vertical motion starts.
(6) When the vertical motion has completed and the cassette is mounted, the capstan motor rotates in the reverse
direction. At that time the position “a” is detected with the cam slider shifted and the loading/capstan
motors are stopped. After 300msec the loading motor rotates in the forward direction and enters the tape
loading operation.
