    Abstract: The invention is to provide a light-focusing for image-gathering device that receive the light coming from the image of an object to be scanned. The light-focusing for image-gathering device is comprised of: at least one reflection mirror, an imaging device and at least one raster (optical grate). The reflection mirror has plural concave surfaces that are arranged appropriately, and the concave surface provide the light to be focused and reflected to a predetermined route. The imaging device receives the light reflected from at least one reflection mirror and converts it into electronic signal. The raster has plural pervious holes, of which positions are just respectively corresponded to each concave surface. The raster is located in the light-path route between the imaging device and at least one reflection mirror. When an image data of an object to be scanned that can be divided into receivable image-and-light signal of the object to be scanned and un-receivable image-and-light signal of the object to be scanned is gathered executively, the un-receivable image-and-light signal of the object to be scanned is first removed, then the adjacent receivable image-and-light signal of the object to be scanned is connected together to obtain a complete image output data.

    Abstract: An image reading apparatus and method is realized which can obtain light correction data with accurately and without involving a complicated operation. A turret including balance filters for a negative film and for a positive film, respectively, is provided in the image reading apparatus. When light correction data is acquired, the turret is controlled so that the positive-film balance filter is inserted and located on an optical axis L of light emitted from a lamp, and in a state in which a photographic film is not set in a film carrier, light correction data is generated based on image data outputted from a line CCD. At the time of reading images on the photographic film, when a negative film is used as the photographic film, the negative-film balance filter is inserted and located on the optical axis L, and when a positive film is used as the photographic film, the positive-film balance filter is inserted and located on the optical axis L. Further, light correction is performed for image data inputted from the line CCD using the above-described light correction data.

    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.
