<p>PURPOSE:To drastically reduce the number of parts and assembly manpower by using a pad brake for a tension servo of an S-reel base in place of a band brake. CONSTITUTION:Press contacting force against a cylindrical part 22 of a braking member 23 integrated with a control lever 21 is varied by detecting tension of a tape 27 with a tension lever 25. By this method, braking torque of the S-reel base 20 is adjusted and hence the tape tension is controlled.</p> |
