Is rotated counterclockwise (second direction), the first
The intermediate gear 4 and the second intermediate gear 5 are rotated clockwise. Since a rotational load is applied to the first intermediate gear 4 and the second intermediate gear 5 by the compression spring 9, the sliding plate 6 rotates counterclockwise (second direction), and The second intermediate gear 5 is a second transmission gear as shown in FIG.
21 and the second reel base 19 is rotated clockwise, and the magnetic tape (not shown) is moved to the first reel hub 25.
To the REW state. At this time, the first and second
The intermediate gears 4 and 5 are acted on by the magnetic tape take-up load of the second reel base 19 so that a force to move in the direction of the drive gear 1 along the second transmission gear 21 acts, and Similarly, a moving force is applied to move the step portion 6c of the first guide groove 6a until the step portion 6c contacts the first guide shaft 11, as shown in FIG.
