<p>PURPOSE:To omit an adjusting mechanism for a drawing out post position by winding a tape always around an A/C head by a drawing arm. CONSTITUTION:Immediately after loading a cassette, the drawing out arm 13 is rotated around a supporting point O in the clockwise direction and a tape 14 is drawn out from the 1st position A of the post 12 to the 2nd position B, and when the tape 14 is wound around an A/C head 5 by a prescribed angle, stopped temporarily. At that time, a P5 post 9 draws out the tape 14 almost at a similar timing to form a tape traveling course. Under said state, stop and FF/REW operation are executed. Since the supporting point O of the drawing out arm 13 is formed on the intersection point between a straight line connecting P to G and a straight line dividing the tape winding angle theta of the post 12 into two parts, the ratio of the change of the tape traveling course from the A/C head to the change of the point B in the rotational direction is reduced even if the point B is slightly dispersed by the dispersion of the drawing out arm 13 or force (f) is applied to the drawing out post 12 by tape tention (t).</p> |
