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 5):
The drive apparatus according to  claim 2 ,\n wherein in a case where said another conveyance roller is disposed upstream of said conveyance roller to be controlled, said second controller controls said brushless motor so that an output torque of said brushless motor decreases when said conveyance roller to be controlled is pushed by said another conveyance roller via said sheet, and controls said brushless motor so that the output torque of said brushless motor increases when said conveyance roller to be controlled is pulled from said another conveyance roller via said sheet, and in a case where said another conveyance roller is disposed downstream of said conveyance roller to be controlled, said second controller controls said brushless motor so that the output torque of said brushless motor decreases when said conveyance roller to be controlled is pulled from said another conveyance roller via said sheet, and controls said brushless motor so that the output torque of said brushless motor increases when said conveyance roller to be controlled pushes said another conveyance roller via said sheet.
