摘要： A line scanning apparatus employing a multiplicity of linear arrays, the linear extent of which is less than the length of the scan line. To permit an entire line to be covered, the arrays are offset from one another in the direction of scan with adjoining array ends overlapped. To correct for the misalignment and redundancy introduced, the image data from the arrays is buffered until a line is completed when readout, is initiated. During readout, cross over from one array to the next is effected within the overlapped areas and the redundant data discarded.

摘要： A full width opto-mechanical modulator comprised of a silicon chip have dual rows or arrays of flexible finger-like reflectors disposed thereon in staggered facing relationship to one another. The reflectors, the surface of which is highly reflective, bend in response to the application of a predetermined potential. The modulator is placed in the path of a beam of high intensity light, and potentials applied to selected reflectors in accordance with an image signal input cause the modulator to reflect light striking the individual reflectors in either an exposure path or against a beam stop.

摘要： A multiple mode image processing apparatus and method. The apparatus, in a copy mode, processes copies xerographically. In a write mode, images derived from image signals are written on the apparatus photoreceptor by a raster scanner, and in a read mode, the raster scanner scans images developed on the photoreceptor to produce image signals representative thereof. A multiple speed drive is provided for the photoreceptor to move the photoreceptor at a high speed when processing copies xerographically and at a lower speed compatible with the data transmission rate for image signals when writing or reading images.

摘要： An image scanner apparatus scans a document and provides image data in digital form representing the scanned document. The compression apparatus detects characteristics of the image data and compresses the image data using parallel compressors, each employing a different encoding scheme. The apparatus then selects compressed image data encoded by one of the compressors in accordance with the detected characteristics and stores the selected data.

摘要： In an input scanner provided with a document input, a sheet feeding path for transporting documents to a scanning station and to a document output; a scanning station having at least a first scanning element, normally fixed in position relative to the sheet feeding path, and supporting a full width array of photosensitive sensors with a coresponding optical arrangement for directing light from the document to the sensors, there is provided an arrangement for bringing the optical arrangement and sensors of the scanning element to a calibration sensing position for detection of a calibration target provided in a fixed position within the input scanner, while retaining the scanning element at a fixed position relative to the sheet feeding path. The arrangement for moving the optical arrangement and sensors of the scanning element to a calibration sensing position for detection of a calibration target may also provide movement to a service position to allow access to the sensors from a position exterior to the input scanner without disassembly of the scanning head from the input scanner.

The optical system includes a first mirror for guiding the laser beam forward along a downwardly inclined slope to the modulator, a second mirror below the modulator for intercepting the beam from the modulator and folding the intercepted beam to guide the beam backwards along a horizontal plane to a third mirror which folds the beam and guides the beam forward along an upwardly inclined slope against the mirrored facets of a rotating polygon, the polygon scanning the beam through a preset scan arc and returning the beam via a focusing lens to the third mirror, the third mirror folding the scan beam and guiding the scan beam forward, and a fourth mirror for intercepting the scan beam and guiding the beam to the object to be scanned.
