| 发明名称 | Light deflector | ||
| 摘要 | An optical deflector includes a movable portion having a mirror plane, a fixed portion, a pair of combined torsion bars connecting the movable portion and the fixed portion to each other so that the movable portion can be rotationally displaced about a rotation axis with respect to the fixed portion, and a driver to drive the movable portion. Each combined torsion bar includes a plurality of torsion bars extending to be parallel to the rotation axis and a plurality of connecting bars, each of the connecting bars connecting one ends of each adjacent two of the torsion bars to each other. A torsion bar farther from the rotation axis has higher torsional rigidity than a torsion bar closer to the rotation axis. | ||

| 主权项 | 1. An optical deflector comprising: a movable portion having a mirror plane; a fixed portion; a pair of combined torsion bars connecting the movable portion and the fixed portion to each other so that the movable portion is rotationally displaced about a rotation axis with respect to the fixed portion; and a driver to drive the movable portion, each combined torsion bar comprising a plurality of torsion bars extending to be parallel to the rotation axis and a plurality of connecting bars, each of the connecting bars connecting one ends of each adjacent two of the torsion bars to each other, a torsion bar farther from the rotation axis having higher torsional rigidity than a torsion bar closer to the rotation axis. | ||
