<p>PURPOSE:To prevent the frange of a tape guide from being pressed to the edge surface of a magnetic tape by changing the height and the inclined angle of the tape guide after the magnetic tape starts to wind around an inclined post. CONSTITUTION:The inclined angle of the inclined post 10 and the final winding angle of the magnetic tape 1 are set so that the deviation of the inclined angle and the height at the magnetic tape 1 is not generated when the magnetic tape 1 is spirally wound around a rotary drum 5 at a prescribed angle. Thus, when the winding angle of the magnetic tape 1 around the rotary drum 5 is smaller than the prescribed angle while loading action, the winding angle of the magnetic tape 1 around the inclined post 10 is made smaller, that is, the quantity of changes in the winding angles and the inclined angles of first and third tape puling-out moving bodies 46 and 48 are made in proportion to the winding angle of the magnetic tape 1 around the inclined post 10.</p> |
