Abstract
A device for controlling positioning of a movable object includes a system for storing therein a provisional target position for the movement of the movable object, the storing system being arranged to store therein the provisional target position by providing an offset with respect to a final target position at which the movable object is to be finally positioned, and a control unit for controlling movement of the movable object, the controlling unit being effective to move the movable object so that, at least during a particular section of the movement, the movable object aims at the provisional target position, and the controlling unit being also effective to introduce, at a predetermined timing, the final target position so that the movable object is moved while aiming at the final target position.
