LENS DRIVING DEVICE USED IN COMPACT CAMERA AND PORTABLE DEVICE ATTACHED WITH CAMERA

摘要

PURPOSE: A lens driving device and a portable device attached with a camera are provided to simplify constitution, to reduce the number of parts, to miniaturize a lens driving device, and to decrease power consumption in a lens driving device and a portable device attached with camera without providing electricity to maintain a lens in a certain position. CONSTITUTION: A lens driving device(1) is composed of a movable body(10) having a lens(14) and a fixed body(24) which moves the movable body in the direction of an optic axis(11) of the lens and supports the movable body. The movable body constitutes a driving magnet(16) and one of driving coils(28,30). The fixed body constitutes the driving magnet and the other driving coil. The driving magnet and the driving coils are set up in the direction of the optic axis to move the movable body using the magnetic attractive force or the magnetic repulsive force.
