<p>PURPOSE:To eliminate the need for a solenoid, etc., and to simplify the mechanism by driving reel bases and a mode changeover gear with a planetary gear which revolves around a driving gear and rotating a capstan and the driving gear with one motor. CONSTITUTION:The changeover for all modes is feasible only by controlling a motor M in its forward and reverse rotation. That is, when the capstan 6 and the driving gear 9 are rotated by only one motor M, the planetary gear 12 revolves around this driving gear 9, and either of the reel bases 2 and 3 is rotationally driven by meshing the revolving planetary gear 12 with one pair of reel gears 4 and 5. Moreover, when the planetary gear 12 is revolved round by one way rotation of the motor M, it is meshed with the mode changeover gear 15 on the way of its revolution locus, and then the mode changeover gear 15 is rotationally driven accordingly. By this method, the need of a solenoid, etc., is eliminated, while only one motor M is enough for the drive, and hence the mechanism can be simplified.</p> |
