<P>PROBLEM TO BE SOLVED: To provide a winding apparatus capable of stably adapted to a wider range of torque. <P>SOLUTION: The winding apparatus 20 includes: a winding shaft 21 that winds up rolled paper RP; a plurality of torque motors (first torque motor 33, second torque motor 34 and third torque motor 35) that rotate a winding shaft 21; a winding diameter detector 32 that detects a winding diameter of the rolled paper RP wound up by the winding shaft 21; and a controller 100 that, based on an output signal from the winding diameter detector 32, controls a plurality of torque motors to be wound up by the rolled paper PR while desired tension is applied so as to be wound by the winding shaft 21. The controller 100 includes a switch circuit 102 that selects a torque motor supplying voltage from a plurality of torque motors and a tension controller 101 that adjusts the voltage supplied to the selected torque motor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
