    Abstract: An image forming apparatus comprising a laser beam radiating unit utilized as a light source, and an optical system that the surface of an original reflects a laser beam radiated from the radiating unit to project an image reflected form the original onto a photosensitive member. In this apparatus, an image is formed selectively in a print mode that an image results from turning on and off the laser beam, in a copy made that a copy of an original results form exposure of the photosensitive member to the laser beam reflected from the surface of an original or in a composite mode that a composite image is formed of a copy of an original and an image resulting from turning on and off the laser beam. Also, this apparatus comprises a reflecting member which is provided on an original supporting table and extends in the sub scanning direction, and a sensor for detecting the laser beam reflected from the reflecting member. A signal produced by the sensor is used as a signal for setting a starting point in outputting image data, a start signal for starting outputting image data in the sub scanning direction and a completion signal for finishing the scanning.

    Abstract: A copying machine of the scanning exposure type has a device for entering the position on a copy sheet where a copy image corresponding to a document image is to be formed. According to the input from the device, the operation timing of a feeder is controlled which feeds the copy sheet to a position where an image formed by scanning exposure on a photosensitive member is transferred from the member to the sheet, such that the copy image is formed on the specified position on the sheet. When an edition copy mode is set or the image forming position input is given with the setting of this mode, the scanner is controlled to move a distance which permits a shift of the document image as specified by the position input.

    Abstract: In an image forming apparatus such as an image reader printer according to the present invention, light is radiated onto an original image by a light source, and a projection image corresponding to the irradiated original image is displayed on a projection screen. Cursors for designating a predetermined region of the projection image corresponding to the predetermined region of the original image are slidably displayed. When the original image is to be copied, the original image irradiated with the radiation light from the light source is optically scanned by a pivot mirror, and the scanning light is shielded by a shutter of a shutter unit only for a predetermined period of time corresponding to the predetermined region designated by the cursors. The shutter is controlled by a controller in accordance with the count of pulse signals generated by a generator that generates the pulse signals having a predetermined period, and shields the scanning light. Upon reception of the scanning light, and an image corresponding to the original image only within the designated region is formed on paper by an image forming unit comprising a photoconductive drum, a developing system, and the like.

    Abstract: A document scanning system is disclosed which utilizes a scan carriage mounted on guide rails which are connected between novel support members. The support members are mounted at one location only to a fixed base support. The guide rails do not require mounting to a side frame structure; the support structure providing the stability usually provided by the sides of a frame. The guide rails are inherently stable and provide the support for the scan load components. The second embodiment of the invention uses a single guide rail to support the optical system rather than plural guide rails.

    Abstract: The present invention is directed to optical imaging systems which utilize linear lens arrays and particularly gradient index lens arrays as the means for projecting light images onto a photosensitive image member. Exposure modulation at the image plane is reduced by oscillating the lens array during an exposure interval, the oscillating period and excursion distance being dependent upon the type of imaging environment the lens is used in. For document copying applications, the requirement for a two-row array to provide minimum exposure modulation is reduced so that a one-row lens array is enabled. For printer and RIS scanning functions, oscillation of a two-row array enables improved system efficiency and hence greater image irradiance and exposure.
