    摘要: A light guide 11 of a rectangular cross-section has side faces 11a, 11b including short sides in the longitudinal direction of which one side face 11a is provided with a light-scattering pattern 20, formed by screen-printing in white paint, for scattering the light incident to the light guide 11. The other side face 11b facing the side face 11a is exposed from a casing 12 to serve as a light-emitting surface. In the present embodiment, it is possible to secure a sufficient amount of light because the whole area of the side face is used as the light-emitting surface. The remaining side faces 11c, 11d of the light guide 11 are side faces including the long sides. Since the side faces 11c, 11d easily produce a surface sink during molding, neither the light-scattering pattern 20 nor the light-emitting surface is provided thereon.

    摘要: A line-illuminating device 10, 20 having a light guide 11, 21 of which the cross-sectional shape is rectangular and its one corner is chamfered to form an emission plane 11a, 21a is provided, in which the light guide 11, 21 is housed in a light guide casing 12, 22, wherein the chamfer dimension of the emission plane 11a, 21a is more than 40% of a height dimension of the light guide 11, 21. By enlarging the chamfer dimension and broadening the width of the emission plane 11a, 21a, the directional characteristics of the emitted light is expanded. In this manner, it is possible to reduce the extent of decrease in the quantity of illuminating light on a document surface when the document surface is elevated.

    摘要: To provide a rod-like light guide and a line lighting device including the rod-like light guide, both of which are easy to include in an image reading device, a contact-type image sensor and an image reading device. For instance, a protruding portion having a flat or curved surface is formed by grinding an end face of a rod-like light guide in a longitudinal direction while leaving at least 80% of the surface area of the end face, and a reflective surface is formed by bonding a heat transfer film to the protruding portion. Thus, even if a portion of the protrusion portion melts when performing thermal processing on the heat transfer film, the portion will not jut out beyond a cross-sectional area of the rod-like light guide, and the rod-like light guide can be easily contained in a case.
