<p>PURPOSE:To travel a tape without twisting it and to use a thin tape for a long time by inclining guide rollers on the both sides of a rotary head drum while keeping parallel relation. CONSTITUTION:A slip post 2 and a guide roller 3 are across arranged and supported to a chassis while keeping the parallel relation not to twist the tape. They are loaded on locker arms 9 and 10 freely slidably supported to pillars 7 and 8 of a supporting stand, and the respective locker arms link the lower end parts by a link panel 11 so as to be slid each other. Since the link panel is moved by a piezoelectric element 12 to be driven by the output of a sensor 4, rotary shafts 13 and 14 of the respective pillars are simultaneously rotated in the same direction, and the slip post and the guide roller are inclined while keeping them parallel.</p> |
