发明名称 Drive mechanism for camera
摘要 A drive mechanism for a camera includes a movable member located behind a photographing lens and linearly moved along an optical axis thereof, the movable member supporting an image pickup device; an AF coil secured to the movable member or an immovable member of the camera; a magnetic force generating device which is secured to the other of the movable member and the immovable member, so as to linearly move the movable member in the optical axis direction relative to the immovable member by applying a magnetic field upon the AF coil; and a controller which controls the direction of electric current flowing in the AF coil so that image light transmitted through the photographing lens is converged onto an image pickup surface of the image pickup device. The AF coil is a planar coil which is wound on a plane parallel with the optical axis.
