    摘要： An automatic document feeder (300) of an image forming apparatus capable of improving a duplex scanning or printing (copying) efficiency includes a single scan path (110) having a document admission passage (112) to admit a document to a document scanning part (200) and a document discharge passage (114) to discharge the scanned document, a duplex scan path (120) having a first document reversing and waiting passage (121) diverged separately from the document discharge passage (114) on the single scan path (110) at the rear of the document scanning part (200) to reverse the document, one surface of which is scanned, and admit the reversed document again to the document scanning part (200), and a document re-reversing path (130) having a second document reversing and waiting passage (131) diverged separately from the document discharge passage (114) on the single scan path (110) at the rear of the document scanning part (200) to reverse the document, both surfaces of which are scanned, again and send the re-reversed document to the document discharge passage (114).

    摘要： An image forming apparatus has an image forming unit that forms an image on one side of a recording medium, and a return unit that returns the recording medium to the image forming unit so that an image can be formed on the other side. A control unit selects different transport speeds for different types of recording media on at least part of the return path, preferably selecting a comparatively high speed for normal recording media and a slower speed for recording media that are thicker or stiffer than normal, as sensed by a thickness or stiffness sensor or inferred indirectly from another setting such as a fusing temperature setting. Thick or stiff recording media can then negotiate tight turns on the return path without transport failure, while normal media can be transported at high speed on the entire return path.

    摘要： Method for producing simplex prints by means of a single pass duplex printer characterised by the steps of :

    using for each printing cycle two sheets and conveying them in coinciding relationship along a common path through said printer,
    forming one toner image on one side of one sheet and forming another toner image on the opposite side of the other sheet while both sheets are simultaneously conveyed through the printer, thereby to produce two simplex prints, and
    simultaneously fixing the images on both sheets.

    摘要： A time required for a copying operation is shortened in making duplex copies from simplex documents. In a copying machine provided with a recirculating document feeder (2) for feeding documents one by one from a document container (6) to an exposure region and returning the exposed documents to the document container (6), when the documents are circulated prior to the copying operation so as to count the number thereof, the copying operation is started immediately in the case where the number of the documents is detected before a first document passes the exposure region.

    摘要： A duplex document handler includes a supply tray (20) on one side of a stationary exposure position (15), a simplex exit tray (32) on the opposite side of the exposure position from the supply tray and a duplex exit tray above the supply tray. A turnover drum (24) receives sheets from the supply tray and guides them past the exposure position and to the simplex exit tray or past the exposure position and through an inverting path to a reversing location (36, 42), back to the exposure position and then back through the reversing location to the duplex exit tray.
