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).
Abstract:
The present invention is made to provide a fixing structure for solid state image forming device made inexpensively and easily by simple caulking adhering method with keeping high positional accuracy, by which it is achieved that the solid state image forming device can be separated easily from the image focusing lens holding member when the image focusing lens holding member has a defect, In the fixing structure of present invention, an image focusing lens holding member 3 and an intermediate holding member 6 are adhered by caulking adhering method. Because one or more projecting portion 3c for painting adhesive material formed on the image focusing lens holding member 3, have smaller area than that of bottom surface 6a of the intermediate holding member 6, a space 10 is formed between the image focusing lens holding member 3 and the intermediate holding member 6, the solid state image forming device 1 fixed on the intermediate holding member 6 can be easily separated from the image focusing lens holding member 3 by inserting and turning a tool 11 whose width of top portion is smaller than the width of space 10.
Abstract:
An image reading apparatus configured to read an image of an original, including: a light source configured to irradiate the original with light; an optical system configured to condense and image a light beam from the light source reflected from the original; a substrate member having a photoelectric conversion unit; a fixing member fixed to the substrate member; a support member configured to support the optical system; and an adhesive bonding the fixing member and the support member together, wherein one of the support member and the fixing member has a protruding portion which protrudes toward the other of the support member and the fixing member, the other has a recessed portion opposed to the protruding portion, the protruding portion protrudes in the recessed portion in a non-contact state to maintain a gap between the protruding portion and the recessed portion, and the adhesive is applied to the gap.
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.
