    摘要: A image reading apparatus includes a plurality of point light sources, arranged in a straight line state, configured to output light for lighting a document situated on a contact glass from a lower side of the contact glass, a light leading member, positioned in front in a light outputting direction of the light output from the point light sources, configured to lead the light output from the point light sources so as to irradiate along a main scanning direction toward the document situated on the contact glass, and a photoelectric conversion element configured to receive reflection light from the document. The light leading member includes positioning means configured to make a gap between each of the point light sources arranged in a line state and the light leading member constant and make an arrangement direction of the point light sources be positioned along a longitudinal direction of the light leading member.

    摘要: A reading light exposure system scans an image recording medium with a reading light beam. The reading light exposure system includes a line source emitting the reading light beam, an optical means which converges the reading light beam emitted from the line source in a direction perpendicular to the longitudinal direction of the line source, and a pinhole array having a number of pinholes which limit the angle of divergence of the reading light beam in the longitudinal direction of the line source with respect to the optical axis of the optical means. The length of each of the pinholes in the direction perpendicular to the longitudinal direction of the line source is larger than the length thereof in the longitudinal direction of the line source.

    摘要: A line-focus system (310) with a curved fluorescent bulb (400, 500, 600) for directing light from the curved fluorescent bulb (400, 500, 600) toward the scan line (314) in the line-focus system (310). The curved fluorescent bulb (400, 500, 600) is shaped in such a manner that the light intensity across the photosensor line array (316) in the line-focus system (310) is relatively uniform and the length of the light bulb (400, 500, 600) is shorter than the prior art. The curved fluorescent bulb (400, 500, 600) may be C-shaped (400), U-shaped (500) or towel bar-shaped (600).
