    摘要: In a light beam scanning device, a plurality of light sources, which irradiates a plurality of light beams in a first direction and is retained by a holder, are disposed at distance from one another in a second direction orthogonal to the first direction. The plurality of light beams are incident, via a coupling optical system, to deflecting and reflecting surfaces of a deflector from a direction that is tilted with respect to a plane orthogonal to the rotational shaft of the deflector. The holder is supported by a housing of the light beam scanning device at a plurality of different positions in a third direction extending from the light source to the coupling optical system.

    摘要: An optical scanner includes a light source, a deflector and a scanning optical system. The scanning optical system includes a first optical system including at least one resin scanning lens, and a second optical system between the target surface and one resin scanning lens. The second optical system includes at least one of a folding mirror(s) and a glass sheet(s), wherein m1+g2=m2+g1 is satisfied wherein m1 and g1 are respectively number of the folding mirror(s) and number of the glass sheet(s) to which the first ray has a shorter optical path than the second ray does, m2 and g2 are respectively number of the folding mirror(s) and number of the glass sheet(s) to which the first ray has a longer optical path than the second ray does.
