<p>PURPOSE:To always hold a proper engaged state with a pinion, and to exactly execute an operation, by supporting an idler gear for transferring the rotating force to 2 reel base gears, on a slide plate. CONSTITUTION:On the same axis as the rotary axial core of feed and winding reel bases 4, 3, reel base gears 4a, 3a of the feed side and the winding side are provided, respectively, and between these 2 gears 4a, 3a, a pinion 14 interlocked with an output shaft 7a of a forward and reverse rotation driving mechanism 7, and a slide plate 16 for supporting an idler gear 17 engaged with said pinion are provided. Between this slide plate 16 and a substrate 2 of a device body 1, a guide mechanism 18 for guiding the slide plate 16 is provided so that the idler gear 17 rocks in a state engaged with the pinion 14 between 2 mutual positions engaged with the feed or winding reel base gear 4a, 3a. Also, a rack 15 which feeds this idler gear 17 through the forward and reverse rotations of the pinion 14 is provided as fixed to the substrate 2.</p> |
