Abstract: An image scanning unit for correcting a variation in magnification caused by an inclination of optical visual-line between a manuscript and a photoelectric conversion element when a full-speed scan reciprocating bed and a half-speed scan reciprocating bed are scanned in the sub-scan direction. The image scanning unit has: an optical system that leads light reflected on the manuscript to the photoelectric conversion element; a marking that is disposed on the optical visual-line of the full-speed scan reciprocating bed; a light source that supplies light to the marking; and a control circuit for accumulating marking information that is input through the optical system to the photoelectric conversion element and detecting an inclination of optical visual-line by comparing the accumulated marking information and regular marking information at regular optical visual-line, and for canceling the variation in magnification in the sub-scan direction caused by the detected inclination of optical visual-line.

Abstract: An apparatus for assembling components of a color optical scanner subassembly which includes a first filter member, a second filter member and a photosensor unit. The apparatus includes an imaging means for impinging an imaging light beam from a line object onto the first and second filter assemblies for producing spatially separated color component images of the line object on the photosensor unit. The apparatus also includes a physical adjustment assembly for holding and selectively adjusting the relative position of the first filter member, the second filter member and the photosensor unit in response to data signals generated by the photosensor unit. This positioning accurately locates the filter members relative to the photosensor unit for optimizing performance of the color optical scanner.

Abstract: A 90* reflector scans a flat document to reflect an image of part of the document into a plane parallel to the document. Then a 180* reflector reflects the image back toward a detection station. A transport made of a cable and pulleys moves the 180* reflector at one-half the speed of the 90* reflector so that the optical distance between the detection station and the document remains constant throughout the scan.

Abstract: A mounting bracket for an image sensing unit of a scanner according to one example embodiment includes a first portion and a second portion extending from the first portion. The first portion has a plurality of elongated holes therein each for receiving a fastener to mount the mounting bracket to a scan head frame. The second portion includes a cutout section therein for allowing an image sensor of the image sensing unit to receive an image from an optical unit of the scanner. A pivot hole in the first portion is centered about a width of the cutout section. When the mounting bracket is mounted on the scan head frame, the elongated holes in the first portion permit linear adjustment of the mounting bracket relative to the scan head frame and the pivot hole permits angular adjustment of the mounting bracket relative to the scan head frame.

Abstract: An image forming method is performed by an image forming apparatus having a head mounting a plurality of writing units that form an image on a recording medium. The writing units are aligned in a sub-scanning direction perpendicular to a main-scanning direction. A part of the image is formed on the recording medium by the writing units, the part of the image forming a line extending in the main-scanning direction. The step of forming a part of the image is repeated while shifting the writing units in the sub-scanning direction by a predetermined amount of shift. The amount of shift of the wiring units is varied so that an amount of misalignment in a connecting portion between the parts of the image on the recording medium is reduced.
