Abstract:
A drive apparatus according to the present invention includes a stepping motor that transmits power to a rotating shaft of a conveyance roller, a brushless motor that transmits power to the rotating shaft of the conveyance roller, a first controller that controls an operation of the stepping motor so that the stepping motor rotates at a constant speed, and a second controller that controls an operation of the brushless motor. The second controller switches control of the brushless motor between, in accordance with a conveyance state of the sheet, assist control in which power of the brushless motor assists a rotation of the stepping motor, brake control in which power of the brushless motor prevents the rotation of the stepping motor, and neutral control in which power of the brushless motor does not affect the rotation of the stepping motor.

Claim (Index 2):
The drive apparatus according to  claim 1 ,\n wherein said conveyance roller to be controlled, and another conveyance roller adjacent to said conveyance roller to be controlled along a sheet conveying direction hold and convey one sheet simultaneously, a conveyance state of said sheet changes in accordance with a speed difference between a sheet conveyance speed of said conveyance roller to be controlled and a sheet conveyance speed of said another conveyance roller, and said second controller detects a load acting on said stepping motor according to said speed difference to switch control of said brushless motor.
