PURPOSE: To prevent noise, undesired sound and damage of caused by the increase of tape tension by providing a rotation member selectively rotating an idler toward a supplying reel or a take-up reel before the motive power of a capstan is transmitted.

CONSTITUTION: When an operation gear is rotated with an upper part clutch gear 33, a lower part clutch gear 34 no longer receives the influence of the slip of a felt 36. After a deck perfectly moves to the state of oppositely and slowly advancing by the power of a loading motor like this, the moment a capstan shaft 4 rotates clockwise to move a tape (T) in the direction of an arrow B', the supplying reel 2 is rotated soon to wind the tape (T). Any noise is generated on a picture in this case and it is possible to move one frame in an opposite direction.
