  • Patent number: 8599450
    Abstract: An image read device is provided, which conveys an original while performing reading of an image of the original at a read position on a transparent member by a read unit fixed, the image read device including: a moving unit that moves the transparent member back and forth in an original conveying direction; a control unit that conveys the original and moves the transparent member by using the moving unit while causing the reading of the image to be performed at the read position; and a determining unit that, when an event causing interruption of original conveyance occurs, stops the transparent member and determines whether a control of returning the transparent member to a home position is to be performed or not in accordance with a stopped position of the original in an original conveying path.

  • Patent number: 8570623
    Abstract: An image reading system reads an image of an original document by conveying the original document through a fixed reading position along a platen glass. The image reading system includes a conveyance device that conveys the original document keeping a prescribed distance from the platen glass at the reading position. The contact glass is arranged outside a depth of focus at the reading position.

  • Patent number: 7953341
    Abstract: An automatic document feeder, included in an image reading system that can be included in an image forming apparatus, is configured to transfer an original document to an image reader included in the image reading system, and includes a first drive unit configured to include a first motor to drive the document separation and feed unit, a second drive unit configured to include a second motor to drive the document conveyance unit, a third drive unit configured to include a third motor to drive the document discharging unit, where at least two motors of the first, second, and third motors disposed in a substantially in-line arrangement, and a cooling member configured to supply a coolant to the at least two motors disposed in a substantially in-line arrangement, to the first, second, and third motors, in that order.

  • Patent number: 7869755
    Abstract: An automatic document feeder, for transferring a document through a scanning position three times, includes: a first transfer mechanism to reverse a given document via a reversing path, and transfer the same to a scanning position; a second transfer mechanism to transfer the given document from the scanning position to one of a switchback path and a document discharging part; a switchback mechanism to transfer the given document to a lay-by on the switchback path, and then transfer the given document towards the reversing path via a re-entry path; and a control unit to control the mechanisms so that a second original document passes through the scanning position a first time before a first original document passes through the scanning position a third time, and to pause travel of the second original document at the lay-by as the first original document is passed through the scanning position a third time.
