PURPOSE: A variable power transmission apparatus having a single shaft and equipment therewith are provided to reduce manufacturing costs by variously controlling each drive member even if multiple drive members are installed in a single shaft. CONSTITUTION: A variable power transmission apparatus having a single shaft comprises a drive shaft(100), a driving source(110), multiple rotatable bobbins(210,220), bobbin drive members(310,320), bobbin driving sources, a gear train, and a control unit. One end of the drive shaft is fixed to a base frame. The driving source drives the drive shaft. The drive members are installed in the drive shaft. The rotatable bobbins are installed in the drive shaft. The bobbin driving sources drive the rotatable bobbins. The gear train connects the bobbins to the driving sources. The control unit controls the driving sources. |
