Patent ID: 8553303

Claim:
An optical scanner comprising: a light reflecting section having a light reflecting surface; a supporting section supporting the light reflecting section; a movable section that supports the supporting section and can turn about a rotation center axis; at least a pair of movable beams extending from the movable section and disposed in such a way that the movable beams face each other with the movable section interposed therebetween; a displacement section connected to one of the movable beams on a side opposite from the movable section; a driving section for driving the displacement section; two drive beams each extending from the displacement section in a direction along the light reflecting surface and perpendicular to a direction in which the movable beam extends; and a supporting frame for supporting the drive beams, wherein the movable beams each include a bending section which is bent and deformed in a thickness direction of the supporting frame by displacement of the displacement section, an end of the supporting section located proximate the movable section is fixed at a position more distant from the light reflecting section than an end face of the movable section that faces the light reflecting section, the supporting section is fixed to a bottom face portion of a concave section of the movable section by being bonded thereto, the displacement section includes a permanent magnet having, along a direction perpendicular to the light reflecting surface, a north pole disposed on a side where one surface of the displacement section is located and a south pole disposed on a side where another surface of the displacement section is located, the displacement section has a through-hole, and the permanent magnet is inserted into the through-hole, and the driving section includes a coil disposed so as to generate a magnetic field in a direction perpendicular to a polarity of the permanent magnet.
