<p>PURPOSE:To miniaturize the device concerned and to adjust the position of a tension pin during traveling of a tape after mounting a cassette by changing stretching directions of the tape. CONSTITUTION:An adjusting end 6a of a reel base braking member 6 is separated from the circumference of a supply reel base 9, and is once wound around a surface 14a of a direction changeover member 14. This surface 14a is a gently curved surface, and a wrapping angle is set within elastic displacement of the member 6. Since the separating direction of the member 6 is changed, an adjusting member 3 can be set up in a slide adjustable place even at the time of mounting the cassette 1, and can be adjusted once reliably. Since an adjusting space is not required for the member 14 like the member 3, the member 14 can be arranged in a place capable of securing the wrapping angle to the reel base 9 at the time of miniaturizing the mechanism. Moreover, by selecting a position of the member 14 and a curvature of the curved surface 14a, a set-up place of the member 3 can be selected independently of the wrapping angle to the reel base 9.</p> |
