Line illuminating device

Two illuminating units 2L and 2R, each having a light guide provided at its one end, with a light-emitting source, are provided. Each illuminating unit is arranged in such a manner that light emitted from its emission plane irradiates the same area of a document-reading plane and the light-emitting source is situated on the opposite side in a main-scanning direction (i.e. the longitudinal direction). By alternately arranging two illuminating units, it is possible to offset characteristics of each illuminating unit so that uniformity and equalization of light intensity distribution can be improved. Since each-illuminating unit is arranged so that its emission plane is symmetric relative to a plane at right angles to the document-reading surface, it is possible to reduce shading that is produced on a document surface when the document surface is not flat.

An imaging optical system a high quality image may be implemented by determining the optimum design conditions for suppressing the generation of ghost while holding uniform and sufficient light using a simulation method. In the imaging optical system having a slit, the requirements for removing the stray light are the inclination of a lens arrangement direction, the slit width, the lens pitch, the view angle, and the height of the light-shielding wall. The slit location, the lens thickness, and the lens row width do not affect the stray light removal, but affect the brightness. In the imaging optical system having no slit, the essential requirements for removing the stray light are the height of the light-shielding wall and the lens pitch. The lens thickness and the lens row width do not affect the stray light removal, but affect the brightness.
