  • Patent number: 6888650
    Abstract: A document reading apparatus and method are provided for outputting an image faithful to a document as possible even if the document is accidentally fed in an oblique fashion on the way of a sheet feeding path. For this purpose, a plurality of document end detecting sensors S1 to S3 are disposed on the way of the sheet feeding path 5, and further, a reading controller 20 calculates a skew quantity ? of the document with respect to the sheet feeding path 5 based on a signal output from the document end detecting sensor, thereby adjusting a document reading timing in accordance with the skew quantity.

  • Patent number: 6775513
    Abstract: An image forming apparatus includes an image reading unit, document convey unit, display/operating portion, and hinge. The image reading unit has a slit glass plate for conveying and scanning a document, and a platen glass plate for fixing and scanning the document. The document convey unit is set above glass surfaces of the slit glass plate and platen glass plate. The display/operating portion is provided to one side of the glass surfaces. The hinge is provided to the other side of the glass plates and serves to attach the document convey unit to be openable and closeable with respect to the glass surfaces. The hinge has an angle stopper with which the document convey unit can be opened at one desired open angle selected from at least two different open angles with respect to the glass surfaces.
