Abstract: There is provided such a shape of a light-guiding body that can guide light emitted from a LED while reflecting such light under conditions which satisfy total reflection as much as possible within the light-guiding body, to thereby improve the light intensity on the surface of a document in the shorter axial direction (i.e., the sub-scanning direction), and also, the light-guiding body has such an optimized shape of a light-incoming face that makes it possible to control the angle of light fluxes in the longer axial direction (i.e., the main scanning direction) to thereby illuminate the surface of the document with light having an uniform intensity distribution. Further, a reflecting member is provided at a position opposite the light outgoing face of the light-guiding body so as to improve the efficiency of illuminating an objective image-reading region on the surface of the document.

Abstract: A light guide capable of reducing the degrading of the read image, even when the document face is raised, by expanding the distribution of light intensities in the longitudinal direction in the position of the irradiated item (document position), and a line illuminator into which the light guide is incorporated. The light guide emits lights incident on an end face from an emitting face extending longitudinally, while having the lights reflected by an internal face of the guide. The sectional shape of the internal face in a direction orthogonal to the longitudinal direction is provided with first and second oval arc curved faces, first and second emitting faces, and a light scattering part formed on the focal position (or a position near the focus) of the oval on the longer axis plane of each oval. The concentrating position of lights reflected by the first curved face and the concentrating position of lights reflected by the second curved face are different from each other.

Abstract: A coating film 9 is formed on a light guide-mounting portion of a frame 2. This coating film 9 presents a color reflecting light over a wide range of wavelength such as a white color. Instead of forming the coating film 9, a light guide 3 can also be mounted through a thin paper-shaped member such as a white-colored paper or a silver-colored paper that allows light to reflect. The coating film or the thin paper-shaped member can be provided not only on the bottom surface of the light guide-mounting portion of the frame 2, but also on the side thereof.
