Abstract:
1. An optical deflector array, which includes electromagnetically actuated optical deflectors, comprising: a first board having movable plates respectively having reflecting surfaces, wirings passing through the respective movable plates, and first connecting portions provided at two ends of the each wiring; a second board having second connecting portions electrically connected to the first connecting portions of the first board, third connecting portions for external electrical connection, and connecting wirings electrically connecting the second connecting portions and the third connecting portions; connecting members that electrically connect the first connecting portions of the first board to the second connecting portions of the second board; and magnetic field generating means for generating a magnetic field; wherein the first board further has, for each of the deflectors, an outer movable plate located outside the movable plate, two inner torsion bars connecting the movable plate and the outer movable plate, a support located outside the outer movable plate, and two outer torsion bars connecting the outer movable plate and the support, the inner torsion bars extending along a first axis, and the outer torsion bars extending along a second axis substantially perpendicular to the first axis, and of four portions of the support divided by two virtual straight lines each of which is on a plane including the first and second axes and divides associated diagonal two of four quadrants divided by the first and second axes, the first connecting portions are located on two portions that exclude connecting portions with the outer torsion bars.
