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: Systems and methods using polarized filtering for glare removal to improve the process of scanning documents, particularly bound documents with glossy content, are disclosed. The system may generally include a lighting source for illuminating a document, a lighting source polarizer attached to the lighting source to polarize light therefrom, a camera for capturing images of the document, and a camera polarizer attached to the camera. The camera polarizer and the lighting source polarizer may be positioned relative to each other so as to facilitate blocking light reflections causing glare off of the document resulting from the lighting source and arriving at the camera. The system may include multiple lighting sources, some or all of which may have a lighting source polarizer attached thereto.

Abstract: A document reading apparatus has a slit along one side of a document support platen of a glass plate to insert one part of an opened book as a document to be read. An insertion pocket forming a recessed space contiguous with the slit and inclined diagonally is provided in the apparatus. A lid is operable between open and closed positions exposing and covering the slit. In the open position, one part of a book can be inserted into the slit with a page in the other part of the book being in intimate contact with the platen, while in the closed position, a sheet as a document can be placed at a proper position on the platen by contacting one side of the sheet to a rim of the lid. This apparatus prevents a problem of image deformation and black image in print output when reading the book.

Abstract: A book scanner comprises a transparent platen, a carriage and a housing. The carriage is disposed in the housing, and the transparent platen with an angular structure is disposed on the housing for an original placed to be scanned. The carriage has a strip-shaped light tube disposed corresponding to the transparent platen. The part of the light source that has the highest luminance is disposed in the position farthest away from the transparent platen, while the part of the light source that has the lower luminance is disposed in the position closer to the transparent platen to assure a uniform and stable luminous intensity of light on each scan line when the light source illuminates the original.
