Abstract:
An imager (50-1) for imaging a document (12) moving in a document track (14) in a table top document processing machine (10) 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 (82-1) and a second line of red LEDs (82-2) are located in the housing to illuminate a scanning line (84) from which image data about the document is obtained by an optical system including a CCD device (100). The imager (50-1) is also designed so that it can be used on either side of the document track (14) to image the front or rear of the document. When two such imagers are used, a white reference member (198) located in one of the imagers is used by the other imager for calibrating the imager to ensure repeatable and uniform data.

Abstract:
Process and apparatus for fabricating an extended scanning or printing array in which several smaller scanning or printing chips (5) are bonded end-to-end onto the surface of a glass substrate (10) having an opaque thermally and/or electrically conductive coating (19) thereon, with the coating removed at discrete sites (24) to allow a photocurable adhesive (30) placed at the sites to be cured through exposure to UV light from underneath the substrate, the photocurable adhesive holding the chips in place while a chip-bonding adhesive (38) deposited on the conductive coating where the chips are located is cured to provide a permanent structure.
Abstract:
The invention relates to a joining construction for mounting the CCD cells of a color line camera on a color splitting prism (30) attached to a prism housing (2). Each CCD cell (6, 7, 8) is attached, by a first glue joint (13), to its fastening element (9), the length (L2) whereof is essentially larger than the length (L1) of the CCD cell, and which fastening element (9) extends from the housing margin (12a) located on one side of said exit surface (20a, 20b, 20c) of the color splitting prism to the other housing margin (12b) located on the opposite side thereof. Each fastening element (9) is attached to said margins by third glue joints (11).
