<p>PURPOSE:To simplify an automatic reciprocating and reproducing mechanism by changing a drive force transmission path of a reel gear from a rotating drive member only by normally rotating and inverting the rotating drive member during a reciprocal inversion to rotate a desired reel gear in a prescribed direction. CONSTITUTION:A pair of rotating drive members 1, 2 giving a driving force to a reel shaft are provided at both sides. Drive gears 17, 18 attached to these rotating drive members 1, 2 are slightly engaged with a transmission gear 19 for transmitting the driving force during their stop and an idler gear 28 receiving a rotating force from the transmission gear 19 also slightly engages with both side reel gears 32, 33. Therefore, during a normal direction reproducing and during an opposite direction reproducing, only by rotating the rotating drive members 1, 2 in the normal direction or the opposite direction, one drive gear 17 engages with the transmission gear 19 and the other drive gear 18 disengages from the transmission gear 19 according to a biting force produced in the respective gears by a rotating direction. The idler gear 28 also selectively engages with one reel gear 32 by the biting force and disengages from the other reel gear 33 to simplify an automatic reciprocating and reproducing mechanism.</p> |
