    Abstract: Provided is a document reading apparatus capable of suppressing a shock that may occur when a trailing edge of a tabbed sheet passes through a roller pair. In an image reading section, when a document to be read is the tabbed sheet, a timing to start separation of the roller pair in response to detection of a trailing edge of the document is delayed by a time period corresponding to a tab length with respect to the timing to start separation when a document other than the tabbed sheet is conveyed. Thus, it is possible to prevent the shock when the trailing edge of the tabbed sheet passes through the roller pair, and to thereby suppress image reading failure due to the shock.

  • Patent number: 8879128
    Abstract: An image reading apparatus is disclosed. The image reading apparatus includes an automatic document feeding unit that transports a document in a predetermined direction while the document floats above a platen glass member and a light source disposed below the platen glass member that irradiates a portion on the document at a predetermined reading location such that reflected light from the portion on the document is converted into image data and a floating distance between the document and the platen glass member is detected to set a value of an image parameter for correcting the image data for the document, based on the detected floating distance between the document and the platen glass member.

  • Patent number: 8867112
    Abstract: In an image reading device, a scanning unit moves relative to the main unit between a base position and a moved position. A conveyance unit moves relative to the scanning unit between a base position and a moved position at which the cover closes the platen, and is formed with a first and second openings. The cover member moves between a base position at which the cover member covers a second opening and a moved position. The first and second detectors detect a state of the scanning unit, the conveyance unit, and the cover member. The conveyance unit conveys the document along one of a first and second conveying paths that is used to convey the document and is determined based on the state of the first and second detectors.

  • Patent number: 8861051
    Abstract: A roller assembly includes a roller shaft, a roller base and at least one roller. The roller shaft defines at least one clipping slot. The roller shaft passes rearward through the roller base to rotatably mount the roller base to the roller shaft. An inside of the roller base extends forward to form an elastic arm. A free end of the elastic arm projects beyond a front surface of the roller base. The free end of the elastic arm defines a hook portion hooked in the clipping slot to restrain the roller base on the roller shaft. The roller is set around the roller base. When the roller assembly is disassembled, press down upon the free end of the elastic arm to make the hook portion project out of the clipping slot, so that the roller base together with the rollers is disassembled from the roller shaft.
