OPTICAL SCANNING DEVICE, IMAGE FORMING APPARATUS, APERTURE FIXING METHOD

摘要

n optical scanning device includes a scanning member, a plurality of light sources, a first reflection mirror, and a second reflection mirror. The scanning member scans incident laser beams in a predetermined main scanning direction. The plurality of light sources emit the laser beams from positions that are different along a sub scanning direction that is perpendicular to an optical axis direction of the laser beams and the main scanning direction. The first reflection mirror is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams emitted from the light sources. The second reflection mirror is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams reflected by the first reflection mirror toward the scanning member.

1. An optical scanning device comprising:
a scanning member configured to scan incident laser beams in a predetermined main scanning direction; a plurality of light sources configured to emit the laser beams respectively from positions that are different along a sub scanning direction that is perpendicular to an optical axis direction of the laser beams and the main scanning direction; a first reflection mirror inclined around the main scanning direction as a rotation axis, inclined around the sub scanning direction as another rotation axis, and configured to reflect the laser beams emitted from the light sources; and a second reflection mirror inclined around the main scanning direction as a rotation axis, inclined around the sub scanning direction as another rotation axis, and configured to reflect the laser beams reflected by the first reflection mirror toward the scanning member.
