Abstract: A compact structure and rapid method for calibrating a document scanner provides for a substantially cylindrical calibration casing having a central axis and an outer surface, with a brightness calibration section of the outer surface encompassing a portion of the circumference of the outer surface, a document width detection segment encompassing a second portion of the circumference of the outer surface, and a document backer element encompassing a third segment of the circumference of the outer surface of the casing. A driver selectively positions the casing in different rotational positions in which the different segments of the outer surface of the cylinder face the optical element of the scanner.

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: A method and apparatus for judging contamination of a scanner in a device having a scanning function, such as a printer scanner, are disclosed. When a data level of a white reference panel which is scanned is above a predetermined reference level, normal scanning is performed. Otherwise, the contamination of a scanner module or the white reference panel is notified to the user. Accordingly, the user can check the scanner or the white reference panel and stable image quality can be obtained by maintaining the scanner clean.

Abstract: An image scanner arrangement (11) having a scanner (14), a document feeder scanning portion (12) and a flat scanning bed (31). A single white plate (43a) is provided between the document feeder scanning portion and flat bed. Before scanning, the scanner (14) scans the white plate to provide image data for testing. If this image data contains white pixels not less than 90%, a controller (82) determines that a lamp (37a) of a light source (37) of the scanner illuminates appropriately. After confirming that the light source (37) is in a good condition, the scanning starts. The single white plate (37a) is utilized regardless of scanning being performed with the document feeder scanning portion or the flat scanning bed.

Abstract: PURPOSE: An image scanning unit and system is provided to install a driving roller near a white member while making the driving roller face an image sensor for reducing a distance between the roller and a reading position of the image sensor so that it makes the scanner smaller and lighter. CONSTITUTION: The system comprises an image sensor(110), a white member(120), and a driving roller(130). The image sensor(110) is installed on a feeding path of a document. The white member(120), whose one side is white, faces the image sensor(110). The driving roller(130), installed at an upper part of the image sensor, feeds a document, to be scanned, between the image sensor(110) and the white member(120) while it rotationally contacts the image sensor(110).

Abstract: A method and apparatus for image reading and image forming. A shading operation is performed by initially setting an operation parameter necessary for the shading operation and an image reading operation. The shading operation is then performed, an image reading operation is executed, and a further shading operation is then performed after the image reading operation. An operation parameter is then again set when a preparation of a next image reading operation is completed, an image reading operation is performed, and then a further shading operation is performed.
