Abstract
An anti-shake apparatus of a photographing-apparatus comprises a movable-unit and a fixed-unit. The movable-unit has an imaging device and a position-detecting coil, and is movable on a plane which is perpendicular to an optical axis of a camera lens of the photographing-apparatus. The fixed-unit supports the movable-unit so as to be movable on said plane, and has a hall element for detecting a position of the movable-unit on the plane. The position-detecting coil is a magnetic-field generating apparatus which is used for detecting the position, and has first and second position-detecting segments. The first and second position-detecting segments are parts of the position-detecting coil, and face the hall element, and are perpendicular to a movement direction of the movable-unit and to the optical axis. The direction of the current through the first position-detecting segment is opposite to a direction of the current through the second position-detecting segment.
