Abstract:
1. An optical scanner comprising: a movable member that includes a light reflecting member with a light reflecting surface and that is rotatable around an X-axis and a Y-axis perpendicular to the X-axis, the X-axis and the Y-axis passing through a center of the movable member; first and second connecters that are respectively provided at each side of the movable member along the X-axis, third and fourth connecters that are respectively provided at each side of the movable member along the Y-axis, each of the first through fourth connecters having a movable beam, a displacement member and two driving beams respectively extending form each side of the displacement member, each movable beam connecting between the movable member and each displacement member, an extending direction of the two driving beams being perpendicular to the each movable beam, the each displacement member having a permanent magnet penetrating therethrough; a coil that is provided at next to the each displacement member opposite to the each movable beam; and first through fourth single fixed members that are provided next to the movable member, wherein each of the first through fourth single fixed members is connected between two of the adjacent first through fourth connecters by each one of the two driving beams of the two adjacent connecters, the each movable beam includes a bending member that deforms the each movable beam by bending in a direction perpendicular to the light reflecting surface, a first beam member connecting between the movable member and the bending member, and a second beam member connecting, between the bending member and the each displacement member, a thickness of the first beam member is thinner than a thickness of the second beam member, a magnetization direction of the permanent magnet intersects with one of the X-axis and the Y-axis and with the extending direction of the two driving beams, and the coil drives the each displacement member.
