20080304117 | IMAGE READING APPARATUS - An image reading apparatus has: a setting unit; a sheet conveying unit; a reading unit which can read an image of the sheet conveyed onto the setting unit by the sheet conveying unit and can read the image of the sheet set onto the setting unit; and an abutting unit which abuts an edge of the sheet which is set onto the setting unit, said edge of the sheet crosses a sheet conveying direction of the sheet conveying unit. The abutting unit is provided at a position where it is not come into contact with the sheet conveyed by the sheet conveying unit. | 12-11-2008 |
20090122367 | IMAGE SCANNING DEVICE AND IMAGE FORMING DEVICE - An image scanning device including: a conveyance path which conveys originals; a first scanning means and a second scanning means which are placed such that they sandwich the conveyance path; and a white reference member used for adjusting the white levels of the scanning means; wherein at least one of the first scanning means, the second scanning means and the white reference member is movable; the first scanning means and the second scanning means can scan the same surface of said white reference member since the first scanning means or the second scanning means is moved or the white reference member is moved. | 05-14-2009 |
20090316222 | IMAGE READING APPARATUS - An image reading apparatus is provided that can prevent image streaks due to dirt, stain or the like from being produced in an image of an original that is read while being conveyed. The image reading apparatus (A) includes an ADF ( | 12-24-2009 |
20100157375 | IMAGE FORMING APPARATUS - The image forming apparatus includes first and second reading portions which read images of first and second faces of an original, an image forming portion which forms an image on a sheet based on image data read by the reading portions, a calculation portion which calculates difference between respective image data, a correction portion which calculates correction data to decrease difference of the image data based on the image data difference, and a control portion which controls the image forming portion so that an image for correction to correct the reading accuracy difference is formed on a sheet based on the correction data; and the calculation portion calculates difference between respective image data when the image for correction formed on a sheet is respectively read by the first and second reading portions, and the correction portion recalculates correction data based on the image data difference calculated by the calculation portion. | 06-24-2010 |
20120113487 | IMAGE READING APPARATUS - An image reading apparatus capable of avoiding an erroneous detection that documents that are not bound are erroneously considered as bound, thus reducing the number of suspended document feeding operations. | 05-10-2012 |
20130278975 | LIGHT GUIDE UNIT THAT GUIDES LIGHT IN AN ORIGINAL DOCUMENT READING APPARATUS - A plurality of LEDs (light emitting diodes) are mounted upon a metallic plate member, and thus heat from the plurality of LEDs is transmitted to the metallic plate member. The plate member functions as a heat radiating plate. In addition, a light guide is fixed to the plate member so that a surface of the light guide and a surface of the plate member that face each other are parallel. | 10-24-2013 |
20130278976 | ORIGINAL READING APPARATUS FOR READING IMAGE OF AN ORIGINAL - A light guide includes a plurality of boss portions. A round hole portion is provided near the center of a base member for fixing the light guide, and slit portions are provided on both ends thereof. The round hole portion supports one boss portion in both the longitudinal direction and the lateral direction of the light guide. The slit portions support boss portions in the lateral direction of the light guide, but are free in the longitudinal direction of the light guide. That is, the center of the light guide is fixed from both directions, and thus both ends of the light guides can expand away in the longitudinal direction. This cuts the influence of expansion by half. | 10-24-2013 |
