Abstract: In a document processing array, an imaging/illumination arrangement for illuminating and imaging the documents at one or several imaging-sites as they are rapidly transported there-past, each site having, as its illumination source, a hollow Lambertian integrating cylinder housing lamps which project essentially all their light onto the inner cylinder walls to be reflected/diffused thereby in Lambertian fashion and sent to the imaging site(s).

Abstract: An arrangement for illuminating objects wherein a large number of objects are rapidly and continuously transported past one or more stations, each illuminated by a cylindrical, integrating Lambertian reflecting/diffusing cavity having one or more like light sources therein so as to generate and project a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating optical guide means to couple said illumination beam to the face of the objects at said station and to couple the reflected image of the object back to the cavity.

Abstract: This invention is a sheet processing array having an imaging station, an in-site, an exit-site and a transport array connecting all of them. The transport array is adapted to advance sheets from the in-site, past the imaging station for imaging the first face of the sheet and to advance it to a reversing transport section. This section has a series of rollers arrayed in a loop which continually rotate in one direction and are adapted to provide non-stop forward movement that turns the sheet over and returns it to present its opposite face to the imaging station for imaging. The sheet is then advanced to the exit-site.

Abstract: In a check processing array, an imaging/illumination arrangement for illuminating and imaging checks at one or several imaging sites as they are rapidly, continuously transported past two or more imaging stations, each station having, as its illumination source, a hollow Lambertian integrating vessel, housing lamps which project a highly uniform, diffuse Lambertian illumination-beam to its respective imaging site.

Abstract: A mounting array for a planar photo-sensitive imaging CCPD disposed in a camera and adapted to facilitate both position-adjustment and securement of the CCPD in five senses, i.e. Left/Right, up/down, in/out, pitch angle and red angle; third array comprising a planar circuit board for receiving and carrying the CCPD; a pair of like threaded posts projected from the camera to penetrate through respective oversized holes in the board; two pairs of front/rear washers each adapted to adjustably affix the board on a respective post and so facilitate Left/Right, up/down and roll angle adjustment of the board in the oversized holes; the washer means also facilitating in/out adjustment of the board and, by differential-adjustment between both washer pairs further facilitating pitch angle adjustment.

Abstract: A set of track gauges for use in aligning, focusing and normalizing an imaging system of a high speed document processor have been provided. Each of the gauges fit within a track (14) in front of the imaging system (10 or 12). The depth gauge (70) is used to align the secondary light beam (26) with the primary light beam (22) so that all documents passing through the track (14) will be evenly illuminated from two points symmetrically offset from a line normal to the track (14). In addition, the depth gauge (70) is used to align a normally reflected beam (32) with a photodetector array (56). Two different trunnion mirrors (54 and 28) are adjusted in the two different alignment operations. The focusing gauge (80) includes a set of black 87 and white 88 stripes positioned on a middle region 86. The white reference gauge (90) has a reflective white coating in its middle region 96.

Abstract: Arrangement for lifting image of checks, with Xenon lamp, Fluorescent lamp or like source of stable-wavelength-output and CCPD Camera means selected to exhibit "close-to-human" spectral response plus a photopic filter, disposed upstream of the Camera and adapted to shift its received image-light spectrum in the direction of that which is optimal for the human-eye.

Abstract: An arrangement for illuminating documents in a document-processing system wherein a large number of documents are rapidly and continuously transported past one or more imaging stations, each station having, for illumination, an integrating structure which houses one or more cylindrical, integrating Lambertian reflecting/diffusing cavities, each cavity having one or more like light sources, so that each cavity generates and projects a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating imaging camera means and optical guide means to couple the illumination beam to the face of the documents at the imaging station and to couple the image of the document to the imaging camera.

Abstract: A skip count clock generator yielding multiple frequencies of clock pulses for variably driving a scanner to produce a required resolution of scanned data includes a base frequency generator of clock pulses and a device for establishing a periodic clock pulse cycle. An electrical logic circuit is used to skip any chosen whole number of clock pulses in a period to yield a desired fraction of the clock pulse cycle.
