Galvanometer mirror and optical switching device using the same

An optical switching device characterized in that a galvanometer mirror thereof comprises at least a mirror;

• a moving body comprising a first coil and a second coil;
• supporting members for supporting the moving body tiltably around at least a first axis with respect to a stationary member;
• and magnetic circuits, wherein light from a first light conducting member is reflected at the galvanometer mirror in which the first coil and the second coil are disposed at both sides of a plane passing through the center of gravity of the moving body and parallel to the surface of said mirror, and the light is selectively incident on a plurality of second light conducting members by controlling a tilt of the galvanometer mirror.
