<p>PURPOSE:To prevent turning transmission torque from lowering by transmitting the turning torque of a motor to an idler through engagement between gears. CONSTITUTION:When a motor 52 turns clockwise, a sun gear 56 turns, but an idler 64 is pressed against a friction member 62 by a compression spring 68 and a stopper 66 to generate turning braking force, so that while the idler 64 does no turn, a rotary lever 58, the idler 64, the sun gear 56, and a motor shaft 54 rotate round the motor shaft as a center clockwise in one body. As a rubber ring 72 comes into constact with a reel turntable 74, the sum gear 56 and a planet gear part 70 turn the idler 64 counterclockwise on a shaft 60 to drive a reel turntable 74 clockwise for roration. When the motor 52 turns counterclockwise, the reel turntable 76 is driven to rotate counterclockwise.</p> |
