Abstract: A light guide emits lights incident on an end face from an emitting face extending longitudinally of the guide, while having the lights reflected by its internal face. A sectional shape of the guide in a direction orthogonal to the longitudinal direction of this light guide has two opposite parabolas, a line segment connecting the focal points of the two opposite parabolas, and a line segment (bottom face) corresponding to the emitting face. A scattering pattern consisting of white ink is formed on the line segment (bottom face) connecting the focal points. With this guide, the face of a document is to be efficiently illuminated by conversely utilizing the characteristic of the compound parabolic concentrator (CPC) to convert scattered lights extending over a full angle from a limited area into radiant lights confined to a prescribed emission angle and thereby minimizing the expansion of lights.

Abstract: A line-illuminating device is provided in an image-scanning device such that the end of a transparent light guide is not disengaged from a casing and uniformity of the light amount can be achieved. A rib is formed unitarily with a resin mold which constructs a light source unit so as to cover an end of a light-emitting plane of the transparent light guide. The end of the light guide can be prevented from being disengaged from the casing by the rib. Another rib is formed unitarily with the end of the casing on the opposite side of the light source unit. This rib covers an opposite end of the light-emitting plane of the transparent light guide, and prevents the opposite end of the light guide from being disengaged from the casing.

Abstract: An image reading apparatus capable of switching between and reading a reflective original and a transparent original is adapted to consume less power and is reduced in size. The evolution of heat by a light source can be suppressed and power consumption reduced by using a solid-state light source such as an LED as light sources for illuminating both reflective and transparent originals. In addition, owing to use of LEDs and sharing of a timing drive circuit, the apparatus per se can be reduced in size.
