  • Patent number: 7782503
    Abstract: An image reading apparatus reads an image from a document being simultaneously fed by the apparatus. A document feeder unit feeds the document on a original plate. A first image reading unit reads an image from the fed document at a first document-read position on the original plate. A second image reading unit reads an image from the fed document at a second document-read position located at a predetermined distance from the first document-read position in a document feeding direction. An abnormal pixel detection unit detects abnormal pixels resulting from rubbish moved between the first document-read position and second document-read position on the original plate together with the document.

  • Patent number: 7719726
    Abstract: There is provided an image reading apparatus for acquiring a read signal of an image by receiving and photoelectrically converting a light reflected from a document. The location of an alien substance on an original plate is detected based on a reflected light received by a light receiving unit adapted to receive a light reflected from a document. When an alien substance is detected, an illumination unit selectively illuminates the location in which the alien substance has been detected. Also, a message which prompts cleaning of the alien substance is displayed. A method of displaying the alien substance location are also provided. Thereby, the image reading apparatus of the present invention can assists a user in cleaning the alien substance such as a dust or dirt on the original plate.

  • Patent number: 7315714
    Abstract: An image forming apparatus includes a controller controlling a movement of a moving member to successively move a plurality of developing devices to a developing position in an image forming operation. A moving distance in at least one moving operation is different from a moving distance in other moving operations. A controller performs at least one moving operation and other moving operations during a transfer operation by a primary transferring device. The controller controls a moving speed of the moving member so that a relative position of a trailing edge of an image forming region on the image bearing member with respect to the developing position is controlled for the at least one moving operation and the other moving operations and so that the moving speed is uniform when the moving member performs a developer supplying operation in a non-image forming operation.
