<p>PURPOSE:To suppress to the utmost the increase in the fluctuation of a tape tension due to external disturbance, by constituting only one of plural guides guiding the supply side of a tape to a rotary head drum into a tilted guide of nonrotation and all other guides with rotating rolls for reducing remarkably a running resistance (friction resistance). CONSTITUTION:The supply side 54a of the tape 54 is led out horizontally in parallel with a mechanism base 55 from a supply reel to a guide 68 through guides 79, 71 a tension regulator pin 83, and a guide 69. The winding side of the tape 54 is led horizontally in parallel also with the mechanism base 55 from the winding reel to the outlet of a drum 63 via a guide 72, a capstan 75, a pinch roll 73, a guide 78, both heads 82, 81 and a guide 77. An intermediate part 54c is regulated obliquely upward with a tilted guide 68, guided as it is with the guides 67, 65 and elevated upward gradually, reaches the guide 64 being a folding guide, is regulated obliquely downward being folded by 180 deg., is descent gradually via a head 80 and the guide 76 as it is and reaches the inlet of the drum 63. The direction and the height of the intermediate part 54c are restricted with the circumferential surface of the drum 63.</p> |
