    Abstract: A method for correcting recording positions of light beams scanned by a light beam scanning apparatus, in which at least one of plural light beams is deflected by an optical deflecting device and all the plural light beams are combined and scanned by a common scanning optical system. The beam position correction data for the optical deflecting device for keeping positions of the light beams constant is obtained by detecting the beam positions before the scanning optical system. The recording positions of respective light beams on a recording surface is also detected to obtain an additional correction data for correcting deviations of the recording positions due to uneven optical power distribution of the light beam or astigmatism of the scanning optical system. The additional correction data is added to the beam position correction data to obtain the final correction data, by which the optical deflecting device is controlled.

    Abstract: A lens unit (U15) includes a housing (45), an upper and a lower lens arrays (A1′, A2′), and a first and a second prisms (4A, 4B). Each of the lens arrays includes a plurality of lenses, a light-shielding member (4), and a plurality of positioning projections, all of which are integral with each other. Downwardly traveling light which enters the housing (45) through a first slit (45c) formed at an upper portion of the housing (45) is directed upward by the first prism (4A) to pass through the two lens arrays (A1′, A2′). The light is then directed downward by the second prism (4B) to exit the housing through a second slit (45d) formed at a lower portion of the housing (45).

    Abstract: A sensor chip arranged in a casing having a window portion on the side thereof to be faced to a medium to be read takes in the form of a single long chip. In particular, a single long and seamless sensor chip having a plurality of photoelectric conversion elements arranged thereon throughout a length of the window portion of the casing is mounted on a long supporting substrate having a length long enough to support the whole sensor chip. The sensor chip and the supporting substrate are bonded together such that transmission of stress due to external force exerted on the supporting substrate to the sensor chip is restricted.
