A read sensor generates front side image information indicating an image on a front side of an object to be read, and front side measurement information indicating a line of an image in a main scanning direction on the front side of a correction chart. A read sensor generates back side image information indicating an image on a back side of the object to be read, and back side measurement information indicating a line of an image in the main scanning direction on the back side of the correction chart. The image correction device calculates an amount of misalignment of read positions based on the front side measurement information and the back side measurement information, and corrects misalignment of images on the front side and the back side of the object to be read, indicated by the front side image information and the back side image information.

An image sensor includes a light source; a bar-shaped light-guiding element having a first light-emitting section, which propagates light from the light source and irradiates an document from an oblique direction, and a second light-emitting section emitting light in a carrying direction of the document; a lens converging the light reflected from the document; a sensor receiving the light passed through the lens; a reflector disposed on the opposite side of the light-guiding element, by reflecting the light from the second light-emitting section such that an optical path of the light emitted from the second light-emitting section is located between the lens and the document, and irradiating the document from an oblique direction; and first and second light-scattering layers formed in areas opposed to the first and the second light-emitting sections, respectively, in the light-guiding element.

An image reader includes a first calculation unit for calculating an output value from an output value of a photodetector adjacent to a specific photodetector in read-width direction; a second calculation unit for calculating a ratio between a first value and a second value, the first value being an output value of the photodetector disposed in conveyance direction of the specific photodetector, and the second value being an output value of the photodetector adjacent, in the read-width direction, to the photodetector disposed in the conveyance direction of the specific photodetector; and a pixel correcting circuit that multiplies the values obtained by the first calculation unit and second calculation unit, substitutes the product for the output value at the pixel position of the photodetector specified by the pixel detecting circuit, and produces as a line output the substitute together with output values at pixel positions of the photodetectors not specified.

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.

A lighting device includes a light source that illuminates an object of illumination, a reflecting member provided opposite the light source so as to direct a first part of illuminating light emitted therefrom to the object of illumination, and a light-blocking member provided between the light source and the object of illumination and between the reflecting member and the object of illumination. The light-blocking member blocks the first directed part of the illuminating light and a second part of the illuminating light directly illuminating the object of illumination with a certain ratio of a light-blocking rate for the first directed part of the illuminating light to a light-blocking rate for the second directly illuminating part of the illuminating light.
