Abstract: A reflector guiding an optical axis is housed in a mirror holder with a compression spring disposed therebetween so that the reflector is biased by the compression spring to move backward. A mirror retainer is rotatably supported by a rear cover for the mirror holder and the reflector is supported by a pair of supporting projections and an adjusting screw to bear against the rear surface of the reflector. The reflector tilts as the projection length of the adjusting screw is changed while the direction in which the effective surface of the reflector faces is changed as the mirror retainer is rotated and thereby the angular position of the adjusting screw is changed.

Abstract: Provided are a light source apparatus capable of preventing a shift in an optical path of a light beam, and an optical scanner comprising the light source apparatus. An optical scanner comprises a light source apparatus in which four light sources corresponding to four colors Y, M, C and B are supported as a unit by one holder. The light sources are integrally disposed in a specific position (a position where the holder is disposed) on an optical base as a supporting base, so even if distortion of the optical base occurs resulting from a dynamic load, ambient temperature or the like, an influence of the distortion is exerted upon each of the light sources supported by the holder to substantially the same extent. Even if a shift in the whole arrangement of the light sources occurs, a large shift in a positional relationship between each light source does not occur.
