Claim Text:
1. A motor control device comprising: a measuring unit configured to output a measurement value corresponding to a rotation speed of a motor; and a control unit configured to control driving of the motor such that the measurement value makes closer to a target value, the target value being between a lower limit threshold and an upper limit threshold, wherein the control unit is configured to: when the measurement value is between the lower limit threshold and the upper limit threshold, control the driving of the motor based on a difference between the measurement value and the target value, when the measurement value is lower than the lower limit threshold, control the driving of the motor based on a difference between a corrected measurement value and the target value, the corrected measurement value being set to a value lower than the target value, and when the measurement value exceeds the upper limit threshold, control the driving of the motor based on a difference between a corrected measurement value and the target value, the corrected measurement value being set to a value higher than the target value.
