MULTI-BEAM LIGHT SOURCE DEVICE, OPTICAL SCANNER, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a multi-beam light source device which has superior environmental stability and assemblability and by which scanning line intervals on a surface to be scanned is exactly set by an inexpensive method; and a light scanner, and an image forming apparatus. SOLUTION: The multi-beam light source device consists of an n-pyramid prism (n≥3) and (n) pieces of semiconductor lasers emitting a light beam toward the prism at its bottom. the reflection direction of (n) pieces of the light beams after reflection by the prism of the light beam emitted from the semiconductor lasers is the specified direction.
