Abstract:
A multi-beam light source device comprising:a light source unit holding light sources and coupling lenses, the coupling lenses coupling light beams emitted by the light sources; a base member holding the light source unit such that the light beams from the light source unit held by the base member are rotatable around an axis which passes through a point of intersection of the light beams and is perpendicular to a sub-scanning cross-section in a sub-scanning direction of an optical scanning device; and an angle adjustment mechanism configured to adjust a mounting angle of the light source unit relative to the base member with respect to the sub-scanning direction, so that respective pitches of beam spots, formed on a scanned surface by the light beams, in the sub-scanning direction are variable in accordance with the mounting angle adjustment.
