<p>PURPOSE:To prevent damage of a tape by locking a locked part of an idler arm in case of fast feeding and fast rewinding to a lock part of a brake bar so as to provide a gap between the idler and the reel base thereby pressing the both and preventing a high tension. CONSTITUTION:The idler 10 delivering a torque of a motor 3 to reel bases 1, 2 is fitted to an idler arm 11 oscillated around a rotary shaft 8 and locked parts 12a, 12b are formed to the arm 11. On the other hand, brake bars 16a, 16b are provided turnably to fixed shafts 13a, 13b and locked parts 20a, 20b are formed to them. In case of fast feeding and fast rewinding, the locked parts 12a, 12b are locked temporarily to the locked parts 20a, 20b and a gap is formed between the idler 10 and the reel bases 1, 2 and then the both area pressed into contact with each other. Thus, a high tension due to rapid contact is eliminated and damages to tape are prevented.</p> |
