Patent ID: 8305671

Claim:
A biaxial scanning mirror for an image forming apparatus, comprising: a first wafer having a plurality of cavities forming a first row and a second row; a plurality of permanent magnets each installed in one of the plurality of cavities, two adjacent permanent magnets of the same row having an air gap formed therebetween; a second wafer, comprising: a mirror unit, rotatable around a first axis, for reflecting light beams; and a rotating unit, formed around the mirror unit, for rotating the mirror unit around a second axis which is perpendicular to the first axis; at least one coil substrate having a planar coil, assembled in the rotating unit, wherein the planner coil is partially inserted into the air gap formed between the two adjacent permanent magnets; and a spacer, formed between the first wafer and the second wafer, for separating the first wafer and the second wafer.
