摘要:
In the lens driving device of the present invention, at least two second coils are disposed at a 90 degree interval in a circumferential direction of a first coil wound around an outer circumference of a lens support in the circumferential direction, at least four magnets are provided at an inner circumferential side of a circumferential wall of a yoke and are provided at even intervals about the circumferential direction of the first coil, each magnet being provided so that an inner circumferential face is the same magnetic pole and opposes an outer circumferential face of the first coil, and in addition is opposite the second coil at the position of providing the second coil. When the lens support is moved in the optical axis direction, an electric current flows in the first coil, and when the lens support is moved in an X-Y direction orthogonal to the optical axis, a predetermined electric current flows in a predetermined second coil.
