◆ HOW TO EJECT THE CASSETTE TAPE
(If the tape is stuck in the unit)
(If the tape is stuck in the unit)
1) Turn the Gear Worm 1 clockwise in the direction of arrow with a screwdriver. (See Fig. 2)
(Other method ; Remove the screw of Motor Load Ass’y, Separate the Motor Load Ass’y)
2) When Slider S, T approachs the unloading position, rotate holder Clutch counterclockwise after inserting screwdriver in the frame’s bottom hole
in order to wind the unwound tape. (Refer to Fig. 3)
(If you rotate Gear Worm 1 continuously when tape is unwinding, you may cause tape contamination by grease and tape damage. Be sure to
wind the unwound tape with the unit in the horizontall position.)
3) Rotate Gear Worm 1 clockwise using a screwdriver until the mecha is in the eject state. Remove the tape. (Refer to Fig. 2)
