摘要： A motor control device for controlling rotation of a motor by controlling a driving voltage applied to the motor is provided. The device includes a driving voltage control unit configured to control the driving voltage, and a detecting unit configured to detect rotation of the motor. The motor has operating characteristics indicative of relationship between the driving voltage and a rotation speed of the motor, where the operating characteristics have a specific dead-band range of driving voltages wherein the rotation speed of the motor is zero regardless of changes in the driving voltage. The driving voltage control unit performs a low rotation control operation including at least one alternating repetition of a first control operation and a second control operation. The first control operation adjusts the driving voltage to have a value outside of the dead-band range from a value within the dead-band range, while the second control operation adjusts the driving voltage to have the value within the dead-band range from the value outside of the dead-band range. The second control operation is performed after a specific first amount of motor rotation has been detected in the first control operation.

摘要： A pump member is cyclically moved to apply an air pressure to a liquid supply source to thereby supply liquid stored therein to a reservoir member. A driving source is driven in accordance with control information to move the pump member. A position sensor senses a position of the pump member. A first storage stores target information indicative of a target driving speed of the driving source. A first calculator obtains drive information indicative of an actual driving speed of the driving source based on the sensed position of the pump member. A second calculator obtains a difference between the target driving speed and the actual driving speed, and obtains correction information for reducing the difference. A corrector corrects the control information with the correction information.
