    Abstract: In order to correct chromatic aberration accurately and read out a document original properly, an image reader apparatus includes a chromatic aberration correction chart, a CCD linear sensor, and a correction processing unit. A chromatic aberration correction chart includes a high reflectance portion and a low reflectance portion lower than the high reflectance portion. A CCD linear sensor receives light reflected from the chromatic aberration correction chart. A correction processing unit corrects chromatic aberration of image data according to a light receiving position in the photoelectric conversion unit receiving light of a first wavelength included in the reflected light from the chromatic aberration correction chart and a light receiving position in the photoelectric conversion unit receiving light of a second wavelength included in the reflected light from the chromatic aberration correction chart.

    Abstract: An automatic document feeder for a copier has the position for reading the image of an original fed by the automatic document feeder disposed near the rear edge of the original table of the copier. In this automatic document feeder, essential parts such as a pickup roller, etc., for feeding originals to the reading position of the original table are arranged concentratedly on the rear side of the copier. Therefore, the center of gravity of the automatic document feeder resides near the rear side of the copier. This automatic document feeder is hinged at the rear side of the copier so as to cover the top surface of the original table in an openable and closable manner. Accordingly, the automatic document feeder is opened and closed with respect to the top of the copier, at a pivot which resides on the rear side near the center of gravity thereof.

    Abstract: An image of the original document is read rapidly to effect quick production of the first copy even when the function of the shading correction and the function of the color/monochrome judgment operate. A waiting position P2 of a first slider 211 is located on the opposite side from a scan starting position P3 in reference to a reading area for the original document, and a location of a shading correction plate 206 is interposed between the reading area for the original document and the waiting position P2 of the first slider 211. While the first slider 211 is in the process of returning from the waiting position P2 to the scan starting position P3 for the preparation of reading the image of the original, a shading correction and a color/monochrome judgment are carried out for preventing the first slider 211 from having extra motion.

    Abstract: An input scanner provided with a document input, a sheet feeding path for transporting documents to a scanning station and to a document output; a scanning station having a first scanning element, fixed in position relative to the sheet feeding path, and a second scanning element, arranged at a home position for substantially simultaneous duplex scanning of sheets fed along the sheet feeding path, and which is also supported for movement past a scanning platen, each scanning element supporting a full width array of photosensitive sensors with a corresponding optical arrangement for directing light from the document to the sensors, there is provided a dual purpose calibration/baffle member, which in a first position serves as a paper baffle along the sheet feeding path to the scanning station to support sheets at the first scanning element, and in a second position, supports a calibration target at a position for detection by the first scanning element. The calibration/baffle member is mounted on the input scanner frame for movement between the first and second positions, and is provided with a bias arrangement which biases the calibration/baffle member for document scanning operation to the first position. The calibration/baffle member is arranged in the path of movement of the second scanning element, for engagement therewith to move the calibration/baffle member to the second position.
