摘要： 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.

摘要： A sensor unit and LEDs are arranged on a sensor board. A light guide is placed above the resultant structure with be parallel to the sensor. The two end portions of the light guide are bent downward at right angles, and the bent end portions serve as incident portions on which light beams from the LEDs are incident. Light entering the light guide emerges from an exit portion to be irradiated on an original. The light reflected by the original is read by the sensor. The direction in which the reflected light is incident on the sensor is parallel with the direction in which the light from each LED is incident on the incident portion. With this structure, in the image sensor, electrical connection between the LEDs, the sensor unit, and an external system is facilitated.

A sheet as an object to be read, coming into contact with the linear reading region, is reciprocally moved in the secondary scanning direction which is perpendicular to the primary scanning direction. The opening is defined by a pair of edges of the case spaced in the secondary scanning direction. Each of the edges includes a convex surface having a top positioned above the outer surface of the cover glass.
