Optical scanner assembly

摘要

An optical scanner assembly includes a plurality of laser beams emitted from a laser light source reflected by a polygonal mirror and incident upon a multi-sided splitter mirror containing two adjacent reflective sides of a polygon, such as a square. The top of the multi-sided splitter mirror is arranged on the incidence center axis, and the aforementioned plurality of laser beams are split to be incident upon two reflective surfaces with the top interposed therebetween.
