Abstract: There is provided such a shape of a light-guiding body that can guide light emitted from a LED while reflecting such light under conditions which satisfy total reflection as much as possible within the light-guiding body, to thereby improve the light intensity on the surface of a document in the shorter axial direction (i.e., the sub-scanning direction), and also, the light-guiding body has such an optimized shape of a light-incoming face that makes it possible to control the angle of light fluxes in the longer axial direction (i.e., the main scanning direction) to thereby illuminate the surface of the document with light having an uniform intensity distribution. Further, a reflecting member is provided at a position opposite the light outgoing face of the light-guiding body so as to improve the efficiency of illuminating an objective image-reading region on the surface of the document.

Abstract: A size-reduced image reading apparatus for optically reading an image drawn on the document surface. The size reduction is achieved this way. Two light sources are so mounted over the document surface at a specific angle formed with the document surface that they are a certain distance away from each other and bilaterally symmetrical. These light sources are surface light emitters made by forming a light-emitting layer on a transparent substrate. And a fiber lens formed of a plurality of bundles of optical fibers is mounted in the gap between the two surface light emitters. Even if the surface light emitter is brought close to the reading position, a uniform illuminance intensity can be obtained at this reading position. Furthermore, if a fiber lens with a small diameter is used in place of the rod lens, the conjugate length can be shortened.

Abstract: A new technique is provided to manufacture a CIS module by employing an alignment-plate, a light-guide plate, and a resolution plate. The above plates can be selected to be pre-fabricated into one piece to reduce the number of components for the CIS module. The dimension of resolution definition structures of resolution plate determines the resolution of CIS module and allows only the reflect light from the image with a desired resolution to pass through. Consequently, it alleviates the butting difficulty in the convention butting operation to form a linear sensor array. Also, a signal reading technique is provided to improve the photo-response of the conventional photo-sensing device. Therefore, operation speed is increased and product performance is improved.
