PROBLEM TO BE SOLVED: To provide a servo control equipment which can normally control scanner driving without being affected by the amount of an offset which a motor current detector has. SOLUTION: A correction means is installed which corrects the output of a motor current detector 21 when a current value detected by the motor current detector 21 is zero. Practically the output of the motor current detector 21 when the motor current value is zero is recognized by a microcontroller 20 via an unipolar A/D converter, and correction is performed to a target current value. As a result, motor control is normally performed irrespective of the value of offset which the motor current detector 21 has. |
