Abstract:
When a rotation start position of a rotation shaft  132  is a middle start position  31 a  (i.e., when rotation of the rotation shaft  132  is stopped in the middle and the rotation is restarted), target rotational speed (relative target rotational speed) is defined using a relative pattern  31  that uses the middle start position  31 a  as a reference, without using an absolute pattern  33  that is defined using a normal rotation start position  33 a  as a reference. Upon detecting that a condition that absolute target rotational speed corresponding to an angular position detected by a rotation sensor  134  is greater than the relative target rotational speed is not satisfied, motor control is switched so that the absolute pattern  33  is used.

Claim (Index 9):
A motor controller for controlling a motor that includes a rotation shaft and that applies, to the rotation shaft, a torque toward an angular position in accordance with control, the motor controller comprising:\n a rotation sensor that detects the angular position of the rotation shaft; and a motor controller that controls rotational speed of the rotation shaft depending on the angular position detected by the rotation sensor, wherein the motor controller determines, based on a detection result by the rotation sensor, whether a rotation start position of the rotation shaft is a predetermined normal rotation start position, wherein, upon determining that the rotation start position is a middle start position other than the normal rotation start position, the motor controller controls the motor using a relative pattern that defines, using the middle start position as a reference, relation between the angular position and relative target rotational speed, so that the relative target rotational speed corresponding to the detected angular position is achieved, and wherein the motor controller uses an absolute pattern that defines, using the normal rotation start position as a reference, relation between the angular position and an absolute target rotational speed to identify the absolute target rotational speed corresponding to the detected angular position, wherein, upon detecting that a condition that the identified absolute target rotational speed is greater than the relative target rotational speed corresponding to the detected angular position is not satisfied, the motor controller controls the motor using the absolute pattern, so that the absolute target rotational speed corresponding to the detected angular position is achieved.
