    Abstract: An apparatus and method for calibrating a scanner connected to a document feeder are provided. In one embodiment, the apparatus includes a calibration strip attached to a rotatable wheel assembly disposed within the document feeder. A cam is provided to rotate the wheel assembly and expose the calibration strip to the field of view of a head assembly of the scanner for calibration. The cam is configured to then rotate the wheel assembly in the opposite direction, so that the calibration strip is no longer exposed to the head assembly. A cleaning blade may be provided to wipe the calibration strip as it is moved to its non-exposed position.

    Abstract: The image reader according to the present invention is able to set the accurate threshold level free of influence of dirt and dust even when the reference nullwhitenull level is requested for shading correction during the acceleration while the carriage is being accelerated without increasing the averaging frequency when the reflected light from the white board is read for shading correction. In addition, because the distance between the head end of the transparent glass and the home position as well as the distance between the home position and the reading window are shortened, the size of the image reader is reduced.

    Abstract: An image forming apparatus includes a document feeder having a stand on which documents are placed and a pair of guide members which move from a center of the stand to sides of the stand. The document feeder feeds a document such that the center of the document moves approximately along the center of the stand. An image reader reads the document to obtain document-shaped image data. An image processor has a memory region to store the document-shaped image data. The memory region has a width whose center approximately conforms with the center of the document-shaped image data. When the image processor conducts an image processing, the document-shaped image data is shifted toward one side of the memory region so that one side of the document-shaped image data is approximately conformed with a reference side of the memory region.

    Abstract: An image reading apparatus comprises a correcting mechanism for correcting an output signal from a reading unit in accordance with a reference level. The correcting mechanism includes a reference element for setting the reference level and a drive mechanism for rocking the reference element between a first position in which the reference element is advanced to a reading position and a second position in which the reference element is retreated from the reading position. The drive mechanism includes a rotating member that is continuously rotated in one direction. As the rotating member rotates, the reference element rocks between the first and second positions, thereby executing correction of the output signal before image information recorded on a recording medium is read.

    Abstract: A method for automatically aligning a charge coupled device of a scanner by using a software contained in the scanner instead of physically aligning the charge coupled device is disclosed. The scanner comprises a charge coupled device (CCD) having an array of optic sensors for converting a reflected line image into an analog signal array, an analog-to-digital (A/D) converter for converting the analog signal array into an image data array, and a test region having a positioning mark in it. The method comprises the following steps of: (1) generating an image data array which comprises the image of the test region in it by using the CCD and the A/D converter; (2) identifying the positioning mark from the image data array; and (3) setting an effective scanning range which defines the start and stop positions of valid image data within the image data array according to the identified positioning mark.

    Abstract: An image scanner having an improved scanning quality is disclosed. Two different color blocks having an interface therebetween are provided on the document platform of the image scanner. The image pickup device passes by the color blocks prior to the document area so that color calibrations and/or error detection can be performed before the scanning operation is performed. By this way, the color data such as the brightness of the obtained image can be compensated, and the deflection rate and/or the amplification error of the image pickup device can be corrected.

    Abstract: A method for positioning the initialization position of a light source for an image reading apparatus operated under a passing-light mode is provided. A platen including a reference area that provides a pattern disposed at a position x is provided. The method comprises a first step of positioning the scan model at the position x in order to read the pattern within the reference area. Secondly, the method moves the light source toward the reference area and, at the same time, triggers the scan module to scan the image. Thirdly, repeat the second step until the image scanned by the scan module meets a pre-determined criterion. Fourthly, the method makes the light source module further move a distance of .DELTA.D-.DELTA.d. The .DELTA.d is the distance traveled by the light source during an interval which begins at the capture of the pattern by the scan module and ends at the determination of the pre-determined criterion as being met.
