Abstract: A structure of a line lighting device permits a rod-like light guide to be attached to a case without rubbing against the case. An end portion of the rod-like light guide provided with a pin is inserted into an opening in a case main body and pushed down, thus making the pin engage with a recess in the case main body. At this time, a distal end of the rod-like light guide is inserted, to some extent, into an opening in a light emitting unit fixing portion. Subsequently, the rod-like light guide is pushed down and pivoted around the pin so as to be completely contained within the case main body. In this state, the distal end of the rod-like light guide is fitted into the opening and the end face of the rod-like light guide is flush with the outer side face of the light emitting unit fixing portion.

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.
