    Abstract: A rod-shaped light guide includes an end face to which light is incident, a bottom plane on which a scattering pattern to scatter light incident to the end face is formed, and a light emitting portion located to be opposite to the bottom plane and emitting light outside. The light emitting portion is formed as a first plane and a second plane connected to each other. The first plane is formed to be smaller than the second plane so that the cross section thereof perpendicular to the longitudinal direction is asymmetrical.

    Abstract: A multi-lightguide document imaging device is proposed for scanning a document transported atop it. The device includes a line image sensor module having a top sensing area and built-in circuitry for converting an incident line image into video signal output; an intervening rod lens for focusing line image lights from the document onto the sensing area; a number or lightguides lightguide-j (j=1,2, . . . ,N) disposed below the document where each lightguide-j has its own built-in light sources, a transverse cross section spaced at a distance SPCj from the scan line an oriented angularly along a θ-coordinate so as to project a line-illumination aiming at the scan line; and an imager frame having a base for holding the line image sensor module, a multi-element support for holding the rod lens plus the lightguides and a scan line backing portion for backing the document.

    Abstract: An image sensor module includes a light source, a light guide elongated in a first direction, a reflector covering the guide, and a light receiver for linear light reflected on a reading target in a second direction perpendicular to the first direction. The guide includes an incident surface for entering light from the light source, a reflecting portion for reflecting, in a direction crossing the first direction, the light from the incident surface, and a surface for emitting light from the reflecting portion as linear light elongated in the first direction. The reflector has an opening and an inclined surface. The opening extends in the first direction to pass the light reflected by the target. The inclined surface, at an end of the opening in the first direction, has a normal which is non-parallel to the first direction and a third direction perpendicular to the first and second directions.
