    Abstract: A light projection unit includes a substrate, a plurality of light emitting elements arrayed on the substrate in a main scanning direction and including light emitting surfaces, a light guide facing the light emitting surfaces to direct light projected from the light emitting elements onto an illumination target and including a first positioning portion, and a holder including a second positioning portion that engages the first positioning portion of the light guide to position the light guide on the holder. The first positioning portion of the light guide is positioned between centers of light emission of adjacent light emitting elements in the main scanning direction of the substrate when the first positioning portion engages the second positioning portion of the holder.

    Abstract: An optical unit including a lens unit including a lens and an optical element configured to receive a light beam focused by the lens, and a support member configured to support the lens unit. Cutouts are provided on joint surfaces of the lens unit and the support member, respectively, such that the cutouts on the joint surface of the lens unit match the cutouts on the joint surface of the support member. The cutouts are configured to accommodate a jig inserted thereinto and rotated to move the lens unit relative to the support member and adjust a position of the lens unit in a direction parallel to an optical axis of the lens.

    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: An image sensor (100) comprises a lens (4), a sensor (6) and a first casing (1). The lens (4) is configured to focus light irradiated toward an object to be read (30) from a direction tilted relative to the X-Z plane, and reflected by the object to be read (30). The sensor (6) is configured to receive the light focused by the lens (4). The first casing (1) is configured to contain or retain the lens (4) and the sensor (6) and to have, in a surface (1j) extending along a main scanning direction, a tilted portion having a length in a sub-scanning direction that decreases toward the object to be read (30).
