    Abstract: In a system for scanning a document (43), a light source (22) illuminates the document; an imager (24, 41, 41', 61, 62) receives light from the document and directs it toward a detector array (25) 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 (46, 46') and image brightness is uniform independent of object off-axis distance. An aspheric element (33) within the imager balances focus variation (82-81-83) within the depth of field with spherical aberration and thereby provide nearly uniform image resolution. A diffraction pattern (33'), carried by the imager, corrects for spectral dispersion which occurs when light passes (63) from air into a refractive material (61, 62). An imager with a reflecting surface (32, 33) provides a system that is subject to little or no chromatic aberration. A solid imager (61, 62) with multiple internal reflecting surfaces (32, 33, 42) in optical series (32-33-32-42), configured to include the previously mentioned optical properties, also provides for highly stable alignment of reflecting surfaces.

    Abstract: A reading pen for reading text has an elongate casing with a reading opening (3) formed in one end thereof, a printed circuit board (5) which is arranged inside the casing, light-emitting diodes (7a, 7b) arranged inside the reading opening and adapted to illuminate the text that is to be read, and a light-sensitive sensor (9) arranged inside the reading opening and adapted to read the illuminated text. The printed circuit board (5) has an end portion at said one end of the casing. The end portion essentially corresponds to the form of the casing. The light-emitting diodes (7a, 7b) and the light-sensitive sensor (9) are arranged on said end portion.

    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: A contact-type linear image sensor has two separate substrates (l2, l4) aligned adjacent to each other A linear array (D) of amorphous silicon photoelectric converting elements serving as photoelectric cells and a matrix wiring unit (28) are provided on a first substrate (l2) Driver IC chips (34, 36) are mounted on a second substrate (l4) Connection pad patterns (20a) for common cell electrodes (20) of cell groups (Dl, D2,..., Dm) and connection pad patterns (32a, 32b, 32c, 32d) for row signal lines (26) of the matrix wiring unit (28) are provided concentrically at a peripheral edge of the first substrate (l2) to be alinged along a junction edge line defined between the substrates (l2, l4). Con­nection pad patterns (38) for the IC chips (34, 36) are linearly aligned at a peripheral edge of the second substrate (l4) and along the substrate junction edge line to oppose the pad patterns (20a, 32a, 32b, 32c, 32d) of the first substrate (l2). A connector unit for electrically connecting the pad patterns of the first and second substrates (l2, l4) may be provided at only one position of the junction edge portion of the first and second substrates (l2, l4).
