An imaging device provides a mobile device multi-feed scanner, which may utilize remote data capture for multi-sheet feed scanning by using mirrors to form a reflective path allowing the viewing of the reverse side of the check on a platform to capture the check image on a mobile device. A camera on the mobile device may either sequentially or simultaneously capture a picture of both the front and back sides of the check. The platform may include a transparent portion, which may be adjacent to a stage portion. The first and second mirrors may be positioned such as to allow imaging of a reverse side of an object through the transparent portion of the platform while the object rests on the stage portion.

An image processing apparatus including two image reading units can sequentially execute image processing of front face image data and back face image data of a document using a single image processing circuit. The image processing apparatus transfers the first face image data of the read document to a first ring buffer and the second face image data thereof to a second ring buffer, respectively, while switching, predetermined unit by unit, whether to transfer the first face image data or the second face image data of the image data to an image processing unit.

A method of digitizing, including accepting papers in an input tray for digitizing, digitizing content of the paper with a first digitizing scanner, digitizing calibration markings with each paper digitized by the first digitizing scanner or digitizing content of the paper with a second digitizing scanner, comparing the calibration markings to predefined markings or comparing the digitized content of the paper from the first digitizing scanner with the digitized content of the paper from the second digitizing scanner, determining if the content of the paper from the first digitizing scanner was scanned correctly based on the, directing the paper to one of two or more output trays by a controller responsive to the determining.

An image forming apparatus includes an image scanning device, which comprises: a document tray to load an original document to be scanned; a discharge tray to load the original document after being scanned; and a frame which the document tray and the discharge tray are mounted on. A conveyance path is formed inside the frame to connect the document tray and the discharge tray. The frame contains a conveying structure to convey the original document along the conveyance path; a transparent support member located below the conveyance path to support the original document; a scanning member located below the transparent support member, the scanning member having a scanning position in which the scanning member scans the original document when being located on the transparent support member; and a pressing member disposed above the transparent support member and facing the scanning member for pressing the original document onto the transparent support member.

An image forming apparatus temporarily stores, in an image memory, image data generated by a front surface reading unit and a back surface reading unit for reading images of a front surface and a back surface of an original respectively. A CPU of an image forming apparatus, at a time of starting a copy job, sets an output frequency of the image memory (transfer rate of image data) to a first frequency F1 that is lower than a second frequency F2. The CPU sets the output frequency of the image memory to the second frequency F2 when transfer of the image data of the first page which corresponds to the front surface of a first original completes.

A two-sided scanning device includes a first image scanning module, a second image scanning module, a first scanning background component, a first brightness calibration component, a second scanning background component, and a second brightness calibration component. When the second image scanning module moves relative to the first image scanning module to a scanning position, the second image scanning module drives the first scanning background component to move relative to the first image scanning module, so that the first image scanning module and the second image scanning module are aligned with the first scanning background component and the second scanning background component, respectively. Therefore, the first scanning background component and the second scanning background component can be scanning backgrounds for the first image scanning module and the second image scanning module to generate a scanning image of an object with a size corresponding to an actual size of the object.

An image reading apparatus includes a shooter where a first mounting surface that is inclined with respect to a horizontal plane is formed thereon, a stacker, a supporting unit that movably supports the stacker in such a manner that the stacker is arranged in a first region or a second region, a conveyance unit that conveys a document from the shooter to the stacker when the stacker is arranged in the first region, and a reading unit that reads an image from the document when the document is conveyed by the conveyance unit, wherein a surface area of a region of the first mounting surface that is covered by the stacker when the stacker is arranged in the first region is greater as compared with that when the stacker is arranged in the second region, and the stacker is formed to be capable of being lengthened or shortened.
