<p>PURPOSE:To simplify the structure, to decrease the number of parts, and to make a titled mechanism more compact, by using an inverting flywheel as a part of a switchable driving mechanism for quick traversing and rewinding. CONSTITUTION:A belt 30 is extended to a pulley 28 of a driving motor 27, and a capstan flywheel 31 and an inverting flywheel 29 are driven. The inverting flywheel 29 and an intermediate gear 38 are supported so as to be freely rotatable by each prescribed control lever. At the time of quick traversing, the wheel 29 is moved in the direction as indicated with an arrow E by operating the control lever, a gear 35 is engaged with 37 and a winding reel 10 is rotated in the direction FF. At the time of rewinding, the intermediate gear 38 is moved in the direction as indicated with an arrow F by operating the lever, gears 38, 39 and 40 are engaged with each other, and a feed reel 11 is rotated at a high speed in the direction REW. Therefore, the structure is simplified, the number of parts is reduced, and this mechanism can be made more compact.</p> |
