LENS DRIVING APPARATUS AND ITS MANUFACTURING METHOD
摘要:
A lens driving apparatus and method may include a movable body holding lenses; a fixed body for supporting the movable body via a spring member to move in the optical axis direction; and a magnetic drive mechanism which has coils held by the movable body and which drives said movable body in the optical axis direction. Additionally, the spring member may be configured with a plurality of spring pieces which are electrically divided at one location in the optical axis direction, and a plurality of coil end portions pulled out from the coils are respectively and electrically connected to different spring pieces of a plurality of spring pieces from each other.
