Title: Maintaining spacing between sheets from and onto which document images are transduced
IPC: H04N1/36
Filed: 1970-02-18
Abstract: 1283514 Reading or printing consecutively conveyed sheets. AMPEX CORP 18 Feb 1970 [20 Feb 1969] 7667/70 Heading H4F In an arrangement in which sheets are consecutively conveyed through a transducing station wherein they are line scanned by a beam of radiation (e.g. light) for transducing image intelligence from or into video intelligence signals i.e. a document reader or printer, the adjacent leading and trailing of consecutive sheets are maintained spaced apart a predetermined distance (thus preventing the sheets overlapping and jamming) by deflecting the transducing radiation beam in the direction of travel of the sheet through the scanning station (in addition to its transverse line scanning), and synchronizing the conveyance of the sheets and the operation of the source of the transducing beam to the frame scan synchronizing signals associated with the video signals. More particularly a signal in time synchronizing relation to a frame sync. pulse commences the conveyance of a sheet through the scanning station, and when the leading edge of the sheet is at the position in which the first line of the raster of scanned lines is formed the scanning of the transducing beam is started in response to a further (or the same but delayed) frame sync. pulse. The video signals may be recorded on a magnetic disc, each picture being recorded on a separate track and that for the first sheet being played-back twice so that two frame sync. pulses are produced, one for starting the conveyance and the other for starting the scanning. Since the beam is also deflected in the direction of travel of the sheet each transverse line scan occurs further downstream from the immediately previous line scan and hence the first and final line scans of each sheet occur at positions separated by the predetermined distance between consecutively conveyed sheets. In the embodiment described the drive for the sheets before they enter the transducing station is intermittent, whereas through the transducing station it is continuous. The sensitized copy sheets may comprise photoelectrostatic sheets which are conveyed past a CRT with a fibre-optic faceplate, or a modulated laser beam scanned over a photographic sheet. The sheet reader may include a camera tube, e.g. image orthicon or vidicon, a flying spot scanner or laser scanner. Instead of electromagnetic visible radiation, electrons, infra-red, ultraviolet, X-rays or γ-rays may be employed. The sheets or documents may comprise papers, films or slides.
