1. A drive mechanism configured to drive a rotator to rotate, the drive mechanism comprising:
a main motor configured to drive the rotator;
an assist motor configured to drive the rotator and assist a drive of the rotator by the main motor; and
processing circuitry configured to:
control a speed of the main motor so that a rotational speed of the rotator is constant; and
control a motor voltage of the assist motor so that the motor voltage of the assist motor changes according to a change in a motor current of the main motor,
wherein a reduction ratio in transmitting a drive from the assist motor to the rotator is a value such that an adjustment range of an assist amount of the assist motor assisting the drive of the rotator by the main motor is equal to or larger than a predetermined width.
