Abstract: The photoelectric converter includes a transparent substrate (1) with a photoelectric converting element opposes a document (6) for reading of image information. A tramsparent support (2) holds the substrate, and a light source (3) is held at a surface of the support opposite to a supporting surface for the substrate. Light emitted from the light source is radiated on a document through the support and the substrate, and reflected light is received by the photoelectric converting element. An adhesive layer (5) retains the substrate on the support which carries conductive tracks (4) for the converting element. A light shield eliminates stray light. A light adjuster enusres uniform light distribution.

Abstract: There is disclosed an illumination device in which a light guide is adapted to emit the light from a face thereof and is provided with an area, on a face opposite to the light emitting face, for diffusing and/or reflecting the light introduced into the light guide from an end face thereof or is provided with uneven light emitting characteristics along the longitudinal direction of the light guide, and the center of the light source positioned at the end of the light guide is placed at a position aberrated from the normal line to said area, whereby attained are compactness, a low cost, a low electric power consumption, a high efficiency of utilization of the light emitted by the light source, and excellent and uniform illumination characteristics. There are also disclosed an image reading device and an information processing apparatus, equipped with the above-mentioned illumination device.

Abstract: An array 3 of LEDs irradiate an image and an array 1 of photosensors produces an electrical signal representing the image. The array of LEDs is arranged in for example four blocks 5-8. Each block is continuously energised within a time slot. The time slots of the four blocks overlap each other. Outside the time slots the light source blocks are intermittently energised. Such a procedure increases the speed of response of the photosensor array. … …
