PROBLEM TO BE SOLVED: To provide an optical scanner that can control a movable part on the basis of a value obtained by beam part deformation detection means irrespective of the occurrence of a change in temperature or a change over time of a beam part.SOLUTION: An optical scanner according to an embodiment of the present disclosure changes a reflection surface of a movable part supported by a beam part constituting a light deflector (24), and includes beam part deformation detection means for detecting the amount of deformation of the beam part, light locus detection means (26) for detecting the locus of reflected light reflected on the reflection surface, storage means (21) for storing the value obtained by the beam part deformation detection means when the locus of the reflected light obtained by the light locus detection means (26) falls within a predetermined setting range, and control means (20) for controlling the movable part to cause the value obtained by the beam part deformation detection means to match the value stored in the storage means (21). |
