摘要： An image scanning device includes a linear light source to illuminate a linear illumination position of a scan target with light, a lens body, and a sensor. The linear light source includes a light guide, a scatterer, an emitter, a stepped portion, and a light-shielding member. The stepped portion is formed, from the end surface of the transparent body along the main scan direction, on a side of the light guide that is opposite to the illumination position side of the light guide. The light-shielding member covers a portion of the emitter of the light guide, the portion including the end surface of the transparent body, and extends beyond the stepped portion in the main scan direction and has an end portion that is located out of a scan range of the sensor in the main scan direction.

摘要： A light guide includes a first exit portion emitting first exiting light, a second exit portion emitting second exiting light in a different direction than the first exiting light, and a reflecting portion reflecting light entering the light guide to each of the first and second exit portions. The first and second exit portions respectively have first and second curved surfaces each having a convex cross section perpendicular to the long axis direction. The second exit portion is connected to the first exit portion in the direction perpendicular to the long axis direction. The reflecting portion is provided, in a plane facing the first exit portion and the second exit portion, at a position shifted in the direction perpendicular to the long axis direction from a position where a normal to the plane passes through a connection portion between the first and second exit portions.

A light emitting surface portion includes first and second light emitting surface portions, the first light emitting surface portion has a longer circumferential length than that of the second light emitting surface portion in the transversal cross section, and circumference curvature of the first light emitting surface portion in the transversal cross section increases away from the second light emitting surface portion. A normal line to the light scattering portion, passing through the center of the light scattering portion in the transversal cross section, intersects with the first light emitting surface portion, at a point at a near side to the second light emitting surface portion in the transversal cross section.
