    Abstract: An image reader for reading an image drawn on a paper or a sheet-like recording medium, an image processor provided with the image reader, such as a copying machine, a scanner and the like, and a fiber lens to be applied to those devices. The image processor has to be large in the whole size of device to read both sides of an original. Therefore, the image processor of the present invention comprises an image reader (10a) on the upper side of transport path and an image reader (10b) on the lower side of that respectively. In order to downsize the device, it is necessary to shorten the diameter of optical fiber (140) of the fiber lens (14) installed in the imager reader as light receiving means. In this case, the optical fiber (140) is provided with a light-absorbing layer 8 (143) around of the optical fiber (140) in order to restrain the crosstalk and the flare phenomenon. The illuminance of light source means (15) installed in the image reader gets smaller as the device is downsized. In case where the illuminance is small, the image quality is deteriorated by the floating of the original. Accordingly, the image reader should be provided with the light source means so as to uniform the illuminance over a specific width of the main and sub scanning directions. Therefore, it is possible to avoid the deterioration of the image quality.

    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: The present invention provides an optics module for a scanning device such as a portable scanner. The optics module includes an illumination source and guide that transmits light through an optical window of the scanning device casing before reflecting off of the object to be scanned. The reflected light from the object travels back through the optical window and a lens before reaching a photosensor for evaluation by an associated microprocessor. The optical window of the scanning device provides a recessed portion in the scanning device casing. The recessed portion of the window is formed using the functional components of the optics module to eliminate a piece of glass typically used within the optical window that can be easily scratched or broken and provides a loss during the illumination process. By using the functional components of the optics module to form the recessed optical window, manufacturing costs to secure and replace a typical glass window contained therein can be eliminated, size of the optics module is reduced, and any contaminates that gather around the optics module can be easily removed by the user.

    Abstract: A sensor unit and LEDs are arranged on a sensor board. A light guide is placed above the resultant structure to be parallel with the sensor. The two end portions of the light guide are bent downward at right angles, and the bent end portions serve as incident portions on which light beams from the LEDs are incident. Light entering the light guide emerges from an exit portion to be irradiated on an original. The light reflected by the original is read by the sensor. The direction in which the reflected light is incident on the sensor is parallel with the direction in which the light from each LED is incident on the incident portion. With this structure, in the image sensor, electrical connection between the LEDs, the sensor unit, and an external system is facilitated.
