A motor control device, comprising: - a drive control device configured to perform an ON/OFF control on a motor; and - a voltage obtaining device configured to obtain a voltage across terminals of the motor, wherein: - the drive control device is configured such that when a motor drive signal of the motor is OFF and the voltage across the terminals of the motor, which is obtained by the voltage obtaining device, has dropped and reached a target voltage, the drive control device sets an immediately following ON time (Ton1, Ton2) based on an OFF time (Toff), Toff2), which is time from when the motor drive signal becomes OFF to when the target voltage is reached, and switches the motor drive signal to ON from OFF, - the drive control device is configured to switch the motor drive signal to OFF from ON when the ON time (Ton1, Ton2) has elapsed upon switching of the motor drive signal to ON from OFF, and the motor control device is further characterized in that the drive control device is configured such that - as the OFF time (Toff), Toff2) becomes longer, (i) the immediately following ON time (Ton1, Ton2) is set to be shorter than when the OFF time (Toff), Toff2) is short, and (ii) a sum of the OFF time (Toff2, Toff2) and the immediately following ON time (Ton1, Ton2), which is one-period-equivalent time, is set to be longer than when the OFF time (Toff), Toff2) is short. comprising: - a drive control device configured to perform an ON/OFF control on a motor; and - a voltage obtaining device configured to obtain a voltage across terminals of the motor, - a drive control device configured to perform an ON/OFF control on a motor; and - a voltage obtaining device configured to obtain a voltage across terminals of the motor, wherein: - the drive control device is configured such that when a motor drive signal of the motor is OFF and the voltage across the terminals of the motor, which is obtained by the voltage obtaining device, has dropped and reached a target voltage, the drive control device sets an immediately following ON time (Ton1, Ton2) based on an OFF time (Toff), Toff2), which is time from when the motor drive signal becomes OFF to when the target voltage is reached, and switches the motor drive signal to ON from OFF, - the drive control device is configured to switch the motor drive signal to OFF from ON when the ON time (Ton1, Ton2) has elapsed upon switching of the motor drive signal to ON from OFF, and - the drive control device is configured such that when a motor drive signal of the motor is OFF and the voltage across the terminals of the motor, which is obtained by the voltage obtaining device, has dropped and reached a target voltage, the drive control device sets an immediately following ON time (Ton1, Ton2) based on an OFF time (Toff), Toff2), which is time from when the motor drive signal becomes OFF to when the target voltage is reached, and switches the motor drive signal to ON from OFF, - the drive control device is configured to switch the motor drive signal to OFF from ON when the ON time (Ton1, Ton2) has elapsed upon switching of the motor drive signal to ON from OFF, and the motor control device is further characterized in that the drive control device is configured such that - as the OFF time (Toff), Toff2) becomes longer, (i) the immediately following ON time (Ton1, Ton2) is set to be shorter than when the OFF time (Toff), Toff2) is short, and (ii) a sum of the OFF time (Toff2, Toff2) and the immediately following ON time (Ton1, Ton2), which is one-period-equivalent time, is set to be longer than when the OFF time (Toff), Toff2) is short. - as the OFF time (Toff), Toff2) becomes longer, (i) the immediately following ON time (Ton1, Ton2) is set to be shorter than when the OFF time (Toff), Toff2) is short, and (ii) a sum of the OFF time (Toff2, Toff2) and the immediately following ON time (Ton1, Ton2), which is one-period-equivalent time, is set to be longer than when the OFF time (Toff), Toff2) is short.
