    Abstract: A line scan camera comprises a printed circuit board upon which a charge-coupled device (CCD) is mounted. A lens component is fixed within a lens mount, and the base of the lens mount is adjustably mounted upon an optical bench. Calibration devices adjustably interconnect the lens mount to the printed circuit board and to the optical bench so as to calibrate the positional location of the lens component relative to the charge-coupled device (CCD) and to an object plane past which objects to be scanned and photographed are conveyed. In this manner, the focus distance defined between the lens component and the charge-coupled device (CCD) as well as the focal distance defined between the lens component and the object plane are fixed and do not need any further calibration. The object plane is defined upon the front surface of a sealed housing enclosure and all of the components are disposed within the housing enclosure so as to prevent dust and contaminants from collecting upon the optical components. LED arrays are disposed within the front of the housing so as to illuminate and properly expose the objects conveyed past the object plane. A positive pressure differential is also created within the sealed housing enclosure so as to prevent the ingress of dust and contaminants into the housing enclosure.

    Abstract: The invention is a system for scanning a document. A light source illuminates the document; an imager receives light from the document and directs it toward a detector array which produces a corresponding array of electrical signals. The imager has several optical properties that are useful either individually or in combination. The imager is telecentric and thereby ensures that image size and magnification are insensitive to object displacement along the optical axis and image brightness is uniform independent of object off-axis distance. An aspheric element within the imager balances focus variation within the depth of field with spherical aberration and thereby provides nearly uniform image resolution. A diffraction pattern, carried by the imager, corrects for spectral dispersion which occurs when light passes from air into a refractive material. An imager with a reflecting surface provides a system that is subject to little or no chromatic aberration. A solid imager with multiple internal reflecting surfaces in optical series, configured to include the previously mentioned optical properties, also provides for highly stable alignment of reflecting surfaces.

    Abstract: A mounting method and a mounting structure for the solid-state image pickup element in the image reading-out apparatus aiming at assembling the element with high precision and eliminating positional deviation occurring thereafter. The mounting structure comprises a solid-state image pickup element fixing member having a focusing lens fixed thereon, a basic board having the element mounted thereon, and a solid-state image pickup element supporting member from which the basic board can be detached. Between the fixing member and the supporting member are provided connecting portions, and the supporting member is bonded to the fixing member by filling the gap between the connecting portions with the adhesive agent. The connecting portions are constructed with the projection part provided on the fixing member and the hole part provided on the supporting member or vice versa.

    Abstract: An imager for imaging a document moving in a document track in a table top document processing machine. The imager includes a housing which is made of several portions which are designed to be assembled quickly with a minimum of fasteners. A first line of green LEDs and a second line of red LEDs are located in the housing to illuminate a scanning line from which image data about the document is obtained by an optical system including a CCDs. The imager is also designed so that the same imager can be used on either side of the document track to image the front or back of the document. When two such imagers are used, a white reference member (for calibrating the imager to ensure repeatable and uniform data) located in one of the imagers is used by the other imager.
