In order to stop the tape in the fast forward mode, when the loading motor 90 is rotated slightly in the reverse direction, the second worm 94 and the second spur gear 93 reversely rotate and the ratchet 156 is rotated. By hitting the lock lever 153 so that the left bent end 153a of the lock lever 153 is separated from the second fast winding operating groove 126 of the fast winding mode plate 150, the plate 150 for the fast winding mode ) Is separated from the operation plate 100, and is rapidly returned to the original position by the restoring elasticity of the lock lever finger spring 154, whereby the operation part 150a and the operation part 150b are supplied to the supply side main brake 80. ) And the winding-up main brake 82 are released, and the supply-side main brake 80 and the winding-up main brake 82 rapidly brake the supply reel 10 and the winding reel 11.

When the capstan shaft 41 rotates in the reverse direction in the play mode and the feed force of the reverse direction is applied to the tape in the jog mode, the idler gear 73 is separated from the take-up reel 11 and then coupled to the supply reel 10. While the tape is loosely loosened and noise is generated, according to the present invention, when the operation plate 100 moves slightly to the right in the play mode, the third gear portion 113 of the operation plate 100 jogs. The idler gear 73 is coupled to the supply reel 10 as the idler mechanism 70 rotates by engaging the clutch gear 160 and the idler mechanism 70 engaged with the jog clutch gear 160 rotates. By rotating the reel 10 slightly counterclockwise, the tape is wound around the supply reel 10, thereby preventing the tape from loosening.

As described above, the present invention enables the user to perform the fast-winding mode in the unloading state and the loading state by using the plate for the fast-winding mode in which the FF / REW gear is coupled to one side of the protrusion. There is an advantage in that the fast forward mode can be selectively performed.
