Abstract: According to aspects of the embodiments, there is provided an apparatus that includes a calibration member that is disposed within a calibration holder and is movable to a position within the optical path of the scanner head assembly. The apparatus can perform optical analysis of images on sheets, comprising a structure forming a baffle for passage of a sheet therethrough, and a photosensor disposed to receive light reflected from a sheet in the baffle. In particular, this embodiment employs a shutter plate mounted to a rack and pinion system where the shutter plate serves the dual purpose of presenting the calibration member to the scanner when engaged into the paper path and when retracted, the backside of the shutter serves as a paper guide.

Abstract: An image reading apparatus which is capable of performing accurate shading correction with simple arrangement while preventing a reference member from being scratched and preventing paper powder and the like dust from being deposited on the reference member. The image reading apparatus includes an image reading unit in which a contact glass guides an original on an image reading location. The contact glass is held by a glass holding member. A line image sensor reads the image on the original conveyed on the image reading location, through the contact glass. The image reading unit further includes a reference member whose image is readable by the image sensor, and a moving mechanism to move the image sensor so as to enable the image sensor to alternatively read the original and a reference surface of the reference member.

Abstract: A multiple non-directional scanning method. A document preview scanning is carried out from one end of the document to the other. The preview image is next analyzed to provide a set of scan parameters. After setting the scan parameters, the scanner performs a backward scanning operation from the other end of the document back to the original start-up position to obtain a final scan image.
