Patent ID: 7636101

Claim:
A MEMS scanner for a laser printer; comprising: a silicon scan plate having a lateral dimension greater than about 4 times its longitudinal dimension; first and second opposed torsion arms, each torsion arm coupled to the scan plate and extending longitudinally from a proximal to a distal point, the first and second torsion arms defining an axis of rotation of the scan plate; first and second opposed mounting structures, each mounting structure coupled to a distal point of a respective torsion arm; and first and second suspensions interposed between the scan plate and respective first and second torsion arms, the first and second suspensions forming a torque spreading apparatus operative to maintain dynamic flatness of the mirror during operation of the MEMS scanner, wherein the first and second suspensions include respective first and second suspension beams and the first and second suspension beams are coupled to the silicon scan plate by respective center connectors and first and second lateral connectors.
