摘要:
An image scanning apparatus includes: a feeding unit; an upstream scanning unit that scans an image of one surface of the document; a downstream scanning unit, which is arranged at a downstream side, and which scans an image of the other surface of the document; a memory unit, which stores both data of the upstream scanning unit and data of the downstream scanning unit; and a control unit that controls the document feeding by performing one of a first feeding process and a second feeding process, wherein the first feeding process is a feeding process in which the upstream scanning unit starts to scan a following document while the downstream scanning unit scans a preceding document, and wherein the second feeding process is a feeding process in which the upstream scanning unit starts to scan the following document after the downstream scanning unit scans the preceding document.

PROBLEM TO BE SOLVED: To enable simultaneously reading double-sided images up to a maximum manuscript size, using a memory capable of storing image data of a manuscript size smaller than the maximum manuscript size.SOLUTION: When a manuscript size is not fixed during carrying the manuscript at manuscript reading in a mixed manuscript mode, according to a read instruction received from a control device corresponding to the manuscript size, which is reported to the control device in a report step, while storing surface image data and rear image data being simultaneously read by reading means by using a first region and a second region, respectively, first reading control reads out and transfers to the control device the surface image data and the rear image data stored in the memory. While storing the surface image data and the rear image data being simultaneously read by the reading means by using the first region or the second region, second reading control reads out and transfers to the control device the surface image data and the rear image data stored in the memory. The first reading control and the second reading control are switched (S410-S438).

PROBLEM TO BE SOLVED: To raise efficiency in processing software by performing processing by required minimum setting, and to attain high productivity and a low cost. SOLUTION: An image processor includes: a scanner CCD 101; a contact image sensor CIS 102; hardware 301 and middleware 302 for performing prescribed image processing with respect to inputted image data; and a primary storage device 107 for temporarily holding the inputted image data. The image processor includes a double-sided simultaneous reading image processing controller for controlling the transfer of the image data between elements. The double-sided simultaneous reading image processing controller divides a processing unit by each image processing request, and allows the image data of the scanner CCD 101 and the contact image sensor CIS 102 to be image-processed by the common hardware 301.

摘要:
A duplex recording method for an image forming apparatus stores page-by-page image data in a storage in the order of page and records, among the image data, two consecutive pages of image data on the front and rear of a recording medium, respectively. At this instant, the method records the image data on the rear of the recording medium carrying an image on the front and a new recording medium alternately by using an interleaf control system. Assume that images are continuously recorded on the fronts of n consecutive recording media at the initial stage of printing. Then, the method continuously records images on the fronts of n+1 consecutive recording media at the final stage of printing. An apparatus for practicing the method is also disclosed.

PROBLEM TO BE SOLVED: To provide an image information apparatus which can transfer each of data of both sides of a document read by a document both-side simultaneous reading means in an optional timing without matching transfer timings of both data to each other when transferring the data. SOLUTION: The image information apparatus is provided with: an image input devices 133, 134 for parallel reading images on both sides of a document; a local memory 116 for temporarily storing one or more pieces of image data read by the image input devices 133, 134; and a hard disk unit for preserving the image data stored in the local memory 116, wherein a PCI bus serving as a transfer path of the image data of both sides of the document, and a PCI transfer controller 152 for controlling communication via the PCI bus are provided between the sides of the image input devices 133, 134 and the local memory 116, and at the side of the image input devices 133, 134, transfer sections 151a, 151b are provided for parallel and individually dispatching the image data of both the sides read by the image input devices 133, 134 to the PCI transfer controller 152.
