<p>PURPOSE:To simplify the constitution and to reduce its size by constituting a differential gear train of the 1st gear which rotates together with a rotating body rotatable around the common shaft of a rotating mechanism, a couple of the 2nd gears which engage the 1st gear and have their rotating shafts provided to the 2nd rotating body, and an internal gear which engages the 2nd gears and rotates around the common shaft. CONSTITUTION:The rotating shaft 47 of an idler gear 28 is arranged in parallel to a common shaft 41 through an arm 29, and rotating bodies 26 and 32 rotate around the common shaft 41. A gear 33 is provided to the rotating body 32 in one body. This gear 33 engages a couple of gears 30 and 31 having rotating shafts 45 and 46 provided to a rotating body 26. The internal gear 34 engages the gears 30 and 31 rotates around the common shaft 41 and is provided with a gear 27 in one body. The gear idler 28 engages a gear 27 and couples with a reel turntable 43 to rotate the reel turntable 43 when turning force is transmitted to the rotating body 26 through a belt 25. The rotating body 26 and gears 33, 30, 31, and 34 constitute the differential gear train.</p> |
