<p>PURPOSE:To make thin the reel drive unit, by the constitution that the intermediate wheel which rotates with two flywheels at the same time is provided and the rotation of the reel is changed over by shaking the play idler through taking the shaft of the intermediate wheel as a fulcrum. CONSTITUTION:The intermediate wheel 13 rotating separately as two flywheels 7, 8 turned with the torque from the motor pulley 4 is provided, and the play idler consisting of two gears or rollers 16, 17 is shaken by taking the shaft of the intermediate wheel 13 as a fulcrum to change over the revolution of the reels 11, 12. Thus, the drive of the reels 11, 12 is shared with the intermediate wheel 13, and the energy due to the moment of inertia of the flywheels 7, 8 can be given to only the capstans 5, 6, allowing to improve the wow-flutter and to make thin the flywheels 7, 8.</p> |
