    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 contact image sensor unit includes: a light source (10) illuminating an original; a rod-like light guide (11) guiding light from the light source to the original; an imaging element (12) forming reflected light from the original on a plurality of photoelectric conversion elements; a sensor substrate (14) on which the plurality of photoelectric conversion elements are mounted; a frame (15) to which they are attached and which has a positioning part (200) for attaching the light guide (11) thereto; and a supporting member (16) which attachably/detachably supports the light guide (11) and is attachably/detachably attached to the positioning part (200).

    Abstract: An illumination device includes a light guide made of plastic, and a light source including a light emitting element whose dominant wavelength is a light emission wavelength in an infrared region, and identifies a banknote. White reference plates are provided at positions that are at opposite ends of a rod lens array and cover respective areas external to an image region across the banknote. A correction coefficient is acquired by calculation. The calculation is made by correcting an illuminance such that IR correction data is substantially identical to IR reference data preliminarily stored in a memory circuit in a signal processor on the basis of IR white reference data representing a white reference illuminance generated from light reflected from the white reference plates. The correction coefficient is used for correcting IR image data when the banknote is read.
