Abstract:
1. An optical deflecting device comprising: a substrate; a pivot member formed on the substrate; a regulating member formed on the substrate; a plate-shaped member having an upper surface as a light reflecting surface; and a group of electrodes formed on the substrate, wherein the plate-shaped member has a loop-shaped bearing portion on a lower surface side, the regulating member has a stopper protruding in approximately parallel to the substrate and embedded inside the bearing portion, with an engagement of the lower surface of the plate-shaped member and an apex of the pivot member and an engagement of an inner surface of the bearing portion and a lower surface of the stopper, the plate-shaped member is rotatably supported with the apex of the pivot member as a center, and a position of the plate-shaped member in a rotation axis direction is regulated by a side surface of the regulating member facing a side surface of the bearing portion, and with an electrostatic force generated between the group of electrodes and the plate-shaped member, the plate-shaped member is rotated with the apex of the pivot member as the center, thereby changing a reflecting direction of a light beam incident to the light reflecting surface of the plate-shaped member.
