Abstract
A light scanner includes a light reflection part having light reflectivity, a movable part having the light reflection part and being rotatable around a first rotation center axis and a second rotation center axis, a pair of movable beams extending from the movable part, a displacement part connected to the movable beams and rotating the movable part around the first rotation center axis, a first drive part that drives the displacement part, a pair of drive beams extending from the displacement part 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, and the movable beam has a bending part that bendingly deforms due to displacement of the displacement part.
