Abstract
Providing a lens driving mechanism that has a rotary cam connected to a cam pin for driving a lens, a rotor directly attached to the rotary cam, and a stator having a plurality of coils provided so as to face a plurality of poles of a magnet disposed along a rim of the rotor. Another lens driving mechanism has a rotary cam connected to a cam pin for driving a lens, a rotor directly attached to the rotary cam, a stator having a plurality of coils provided so as to face a plurality of poles of a magnet disposed toward the center of rotation along a rim of the rotor. Electronic device equipped with the lens driving mechanism is also provided.
Claims6
A lens driving mechanism comprising:
- a rotary cam connected to a cam pin for driving a lens;
- a rotor directly attached to said rotary cam;
- and
- a stator having a plurality of coils disposed so as to face a plurality of poles of a magnet provided along a rim of the rotor, wherein said rotary cam and said rotor are flat-plate shaped, said rotor being directly superposed on said rotary cam and attached to each other.
