Abstract

PURPOSE:To stabilize the position of a magnetic tape without reference to the direction of the running of the magnetic tape, by constituting the rotary roller of a magnetic-tape drawing and guiding means by using a cylindrical rotary roller body and a roller shaft whose external circumferential surface coming into contact with the internal circumferential surface of the roller body is different in diameter. CONSTITUTION:A rotary roller, composed of a roller shaft 11 having a taper surface 11a and a cylindrical rotary roller body 12, is provided to a moving body 7, and the roller shaft 11 is provided with a flange 13 and a coming-off stopper 14. As a magnetic tape 1 runs to the right, the rotary roller body 12 slants to the right by running-directional frictional force and its internal circumferential surface comes into contact with the taper surface 11a of the roller shaft 11. When it runs to the left, the rotary roller body 12 slants to the left. Thus, the running direction of the magnetic tape is reversed, the body 12 is positioned on one widthwise end side to run the tape.
