Abstract: A solid-state scanning apparatus for scanning the surface of an original to convert light information into electrical signals suitable for application to a facsimile system is provided. The scanning apparatus comprises a stationary original holder, on which an original to be scanned is placed, a stationary optical system including a solid-state line sensor comprised of at least two CCD image sensing devices arranged in a line to carry out the split scanning with a predetermined overlapping scanning section between the two adjacent scanning sections, a pair of first and second storing devices provided for each of said CCD image sensing devices, a control circuit for controlling the operation of the CCD image sensing devices and the storing devices, and a reciprocatingly movable mirror system for leading the light information of the original to the solid-state line sensor.

Abstract: An original document for facsmile transmission or the like is fed over a horizontal transparent platen by rollers for scanning. A light source illuminates the document and a mirror reflects a light image of a linear portion of the document perpendicular to the direction of movement horizontally to a converging lens. The light image from the lens is reflected upwardly by another mirror onto the light receiving surface of a linear photosensor array. The light receiving surface of the array faces downwardly, minimizing accumulation of dust thereon. A light baffle in the form of a box is provided between the first mirror and converging lens and is formed with apertures for the light image to pass therethrough. A scan drive and amplifier circuit for the array is mounted closely adjacent thereto while a signal processing circuit comprising a quantization means is mounted on the box and electrically connected to the drive unit. The various units of the apparatus are individually detachable for ease of servicing.

Abstract: In an electrostatic copying machine, a light source radiates an elongated, narrow beam of light onto an original document which is moved perpendicular to the beam of light for scanning. A plurality of imaging optical fibers are arranged in a row extending coextensively parallel to the light beam, which focus images of adjacent portions of the document onto a photoconductive member which is moved in a manner conjugate to the original document for scanningly forming an image of the document on the photoconductive member. The imaging optical fibers themselves extend parallel or at an angle to the document. First and second reflectors which may be mirrors or prisms are disposed between the document and imaging optical fibers and between the imaging optical fibers and the photoconductive member respectively to deflect the optical paths of the images.

Abstract: A bar lens array is mounted between an original document and a photoconductive member in such a manner that the ends of the bar lenses are equally spaced from the document and photoconductive member regardless of manufacturing differences in the length of the bar lenses of the array. Reference marks may be provided at the center of the bar lens array and at a point halfway between the document and photoconductive member which are aligned with each other. The bar lens array may be mounted in a sleeve which compensates for the length of the bar lenses. In this embodiment, a stopper is provided at a fixed distance from one of the document or photoconductive member. The distance C from one end of the bar lens array to a point on the sleeve adapted to align with the stopper is C=(D-L)/2-K where D is the distance between the document and the photoconductive member, L is the length of the bar lens array and K is the distance from the stopper to the one of the document or photoconductive member.

Abstract: A rectangular array of rod lenses is arranged between an original document and a photoconductive member, and the document and photoconductive member move relative to the rod lens array at the same speed. The document is illuminated for three sequential color separation exposures so that three color images are formed on the surface of the photoconductive member by the rod lens array. Due to the construction of the means for illuminating the document, the brightness of the illumination is different for the three color separation exposures. This is compensated for by varying the number of rod lenses for the three color separation exposures and thereby the cross sectional area of the rod lens array which constitutes an exposure aperture so that the effective brightness of illumination is the same for the three color separation exposures.

Abstract: A plastic casing in which bar lenses are imbedded is formed with longitudinal grooves in the sides thereof. The bifurcations of a bifurcated pull rod are guidingly slidable in the grooves. A frame is connected to the pull rod for movement therewith and has portions facing the end faces of the bar lenses to which is fixed a cleaning material such as cloth. Movement of the pull rod, frame and cleaning material results in the cleaning material moving over the faces of the bar lenses to clean the same.
