A line type illuminator comprising a plurality of light sources at a side of one end of a rod-like transparent light guide, wherein an auxiliary light scattering pattern is formed with two (2) spot-like patterns, which are provided at positions being shifted from a center line of a main light scattering pattern in the longitudinal direction and are separate in a width direction, for maintaining evenness or uniformity of illumination intensity in a longitudinal direction. Normal lines of those two (2) spot-like patterns and the center line of any one of the plurality of light sources, extending in the longitudinal direction, intersect each other. Specifically, the longitudinal center lines of the red-color light sources and the green-color light source intersect the respective normal lines of the spot-like patterns 21a and 21a. |

DETAILED DESCRIPTION What is claimed is: 1.
A line type illuminator having a scanning direction in a longitudinal direction, and a sub-scanning direction being orthogonal to said scanning direction and being narrow in width thereof, comprising: a light source unit being constructed with a plurality of light sources, each of which can be activated independently; a rod-like transparent light guide, having a reflective surface opposing said light source unit at one end in the longitudinal direction thereof; and a case, in which the rod-like transparent light guide is received, wherein said rod-like transparent light guide is formed to have a polygonal cross-section thereof, a chamfered portion formed as a light emission surface and formed in the longitudinal direction at a comer thereof, and a main light scattering pattern formed in a portion intersecting a normal line of said light emission surface and opposing thereto, wherein an auxiliary light scattering pattern is provided between said main light scattering pattern and said light source unit, and said auxiliary light scattering pattern is shifted outside from a longitudinal center line of said main light scattering pattern, and further a normal line from the auxiliary light scattering pattern intersects a center line of any one of said plurality of light sources extending in the longitudinal direction.
2.
A line type illuminator as defined in claim 1, wherein said auxiliary light scattering pattern is formed as a pattern of light-scattering discrete spots and is provided in a position corresponding to said plurality of light sources.
3.
A line type illuminator as defined in claim 1, wherein said plurality of light sources comprises three light sources, and said auxiliary light scattering pattern is formed with two or three spot-like patterns being separated in a width direction of said rod-like transparent light guide.
4.
A line type illuminator as defined in claim 1, wherein said rod-like transparent light guide of said main light scattering pattern has an engaging portion in a concave and convex shape, and is provided with a pattern omission portion corresponding thereto
