ABSTRACT:
An optical system driving apparatus is capable of vertically and horizontally driving an optical lens, a part of the lens or a complete optical system including the optical lens. The apparatus is miniaturized and lightened in order to have a rapid response characteristic and a wide control limit, by the utilization of a single magnetic circuit forming a ferromagnetic field between two magnets, and an electronic circuit having a plurality of coil elements having a force acting in each direction in a ferromagnetic field. The optical system is placed in the magnetic field between the two magnets and interlinked to the coil elements, thereby occupying minimal space.
