Abstract: A lighting device includes a light source that illuminates an object of illumination, a reflecting member provided opposite the light source so as to direct a first part of illuminating light emitted therefrom to the object of illumination, and a light-blocking member provided between the light source and the object of illumination and between the reflecting member and the object of illumination. The light-blocking member blocks the first directed part of the illuminating light and a second part of the illuminating light directly illuminating the object of illumination with a certain ratio of a light-blocking rate for the first directed part of the illuminating light to a light-blocking rate for the second directly illuminating part of the illuminating light.

Abstract: A lens array unit includes first and second lens arrays cooperative with each other. The first lens array is provided with a plurality of first convex lenses and a first transparent holder formed integral with the first lenses. Each of the first lenses has first and second lens surfaces. The second lens array is provided with a plurality of second convex lenses and a second transparent holder formed integral with the second lenses Each of the second lenses has third and fourth lens surfaces. The second lens array is attached to the first lens array so that the third lens surfaces face the second lens surfaces. The lens array unit further includes a light shield mounted on the first lens array. The light shield is formed with a plurality of through-holes each facing the relevant one of the first lens surfaces.

Abstract: In an image reading device in which an original is illuminated by a light source, and a reflected beam from the original is imaged on a sensor through a rod lens array, a light-shielding member is arranged between the beam exit surface of the light source and the incident surface of the rod lens array to prevent the beam from the light source from being directly incident on the rod lens array to cause a flare. An image reading device and information processing apparatus in which the image quality is rarely degraded by the flare beam are provided.

Abstract: A stray light baffle for reducing an amount of stray light incident on a detector may comprise a main body portion and a mounting pad portion. The mounting pad portion is affixed to a mounting surface with a light curable adhesive. The stray light baffle substantially blocks stray light and substantially transmits curing light. The mounting surface is located adjacent the detector so that the main body portion of the stray light baffle is interposed between the detector and a source of stray light when the stray light baffle is mounted to the mounting surface.
