Patent ID: 8599460

Claim:
A micromirror device comprising a reflecting portion and an electrode portion facing the reflecting portion, said reflecting portion comprising at least: a first plate-shaped movable beam and a second plate-shaped movable beam each having one end fixed and the other end displaceable, said first movable beam and said second movable beam being arranged in a line at a predetermined distance while said other end of said first movable beam faces said other end of said second movable beam; a plate-shaped mirror which is arrayed in a line with said first movable beam and said second movable beam and rotationally arranged between said first movable beam and said second movable beam; and a pair of a first connector and a second connector each of which connects said other end of a corresponding one of said first movable beam and said second movable beam to said mirror, and said electrode portion comprising at least: a first driving electrode for said first movable beam which faces said first movable beam at a predetermined distance; a second driving electrode for said second movable beam which faces said second movable beam at a predetermined distance; mirror driving electrodes which face said plate-shaped mirror at a predetermined distance; wherein said first movable beam and said first driving electrode for said first movable beam are arranged face to face in a thickness direction of said first movable beam, said first movable beam completely overlaps said first driving electrode, and said displaceable end of said first movable beam is displaced to be attracted toward said first driving electrode for said first movable beam; said second movable beam and said second driving electrode for said second movable beam are arranged face to face in a thickness direction of said second movable beam and said first movable beam completely overlaps said first driving electrode; and said displaceable end of said second movable beam is displaced to be attracted toward a facing surface of said second driving electrode for said second movable beam.
