偏向器。 Dynamic pressure bearings are constructed at the upper and lower parts of the hollow rotating shaft and the fixed shaft, and the shaft is made to float by the repulsive force of a plurality of magnets, and is composed of the hollow rotating shaft, a mirror, a rotor magnet assembly, and some of the magnets. In an air magnetic bearing type optical deflector in which the driving source of the rotating body is a surface facing type motor equipped with the rotor magnet assembly, the plurality of magnets form pairs at the upper and lower ends of the hollow rotating shaft, and the plurality of magnets form pairs at the upper and lower ends of the hollow rotating shaft. The magnets are concentrically and radially magnetized, each pair of magnets is axially offset and the direction of the offset is opposite at the top and bottom, and the hollow rotating shaft is axially magnetized at the top and bottom ends. An air magnetic bearing type optical deflector characterized by being open to the air.
