Patent ID: 8717653

Claim:
A light scanner comprising: a light reflection part having a light reflection surface; a movable part having the light reflection part and being rotatable around a first rotation center axis and a second rotation center axis orthogonal to the first rotation center axis, the movable part being supported only by a pair of movable beams extending from the moveable part and oppositely provided with the moveable part in between; a pair of displacement parts connected to each of the movable beams and producing displacement of rotating the movable part around the first rotation center axis; a pair of first drive part that drive each of the displacement parts; a pair of drive beams extending from the displacement parts in parallel to the light reflection surface and orthogonal to an extension direction of the movable beams; a support frame that supports the drive beams; and a second drive part that rotates the movable part around the second rotation center axis, wherein the movable beam has a bending part that bendingly deforms in a thickness direction of the support frame due to displacement of one of the displacement parts; each of the displacement parts includes a first permanent magnet, the first drive parts each include a coil that generates a magnetic field acting on the first permanent magnets, the movable part includes a second permanent magnet, and the second drive part includes a coil that generates a magnetic field acting on the second permanent magnet.
