MECHANISM OPERATION DESCRIPTION

5. In the same way. during FF and HEW, the ED plate

operates when the tape end is reached, When the
plate (64) moves (0). the lock plate (96) rotates
I 6) and the FF/REW lever is released, causing
the deck to enter play mode ( 6).

6. The pin at the lower side of the reel disk assembly

(22) resets the ED plate (28) I 6).
Fig. 23

EJECT

1. Press the'EJ lever (61) ( 0 ).

2. The push plate (58) is pushed by the EJ lever (61)
and rotates the push arm (83) I 9).

3. The push arm (83) moves the head plate (2) back

- (9 ).

4. The EJ lever (61) moves the rod (52) and rotates
the PE plate (44) ( 0).

5. The holder (48) moves up following the push plate
I58) groove I O).

6. The PE plate (44) turns the reverse spring (47) over

and pushes out the pack slider (50) I 0).
