<p>A control apparatus for controllably driving a drive mechanism (25) which displaces a movable member (211), includes: an electric-current detecting unit (27) configured to detect electric current for driving the drive mechanism; a speed control unit (32) configured to set a target eleetric-eurrent according to a drive speed at which the drive mechanism (25) is caused to drive the movable member (211); and an electric-current control unit (333) configured to multiply, by an integral gain and a proportional gain, an electric-current deviation between a target electric-current and a detection electric-current detected by the electric-current detecting unit to set output electric-current to be output to the drive mechanism, wherein the current control unit changes at least one of the integral gain and the proportional gain according to the drive speed of the drive mechanism.</p> |
