Patent ID: 6972890

Claim:
An MEMS mirror device comprising: a rectangular frame; a mirror unit including a reflecting portion on one face thereof, connected via hinges inside the frame and formed on the same plane as the frame; a drive unit including an electromagnetic coil of eight-figure type wired on the other face of the reflecting portion of the mirror unit, and a permanent magnets; an elastic unit, wherein: the frame, the mirror unit, and the hinges are integrally formed of the same material; the frame has two protruding portions spaced at a regular interval and extending into the frame on both sides of a connected portion with the hinge; the drive unit oscillates the mirror unit around an oscillating axis with the hinges; the permanent magnets generates a magnetic field to cause a Lorentz force in a direction for oscillating the mirror unit in a predetermined part of the electromagnetic coil in flowing a current through the electromagnetic coil; and the elastic unit made of gel-like high molecular resin is provided to bridge the hinge between the two protruding portions.
