Abstract: There are provided a light emitting unit in which temperature increase due to heat generated in a light emitting element is suppressed to enhance light emission efficiency, a linear illumination device in which the light emitting unit is incorporated, and a contact-type image sensor and an image scanner in which the linear illumination device is incorporated. A lead frame 23 in the light emitting unit has an extension 29. The extension 29 is folded along a case 12, and a plate-shaped heat dissipater 30 is connected to the extension 29. The connection is carried out by forming holes 29a and 30a in the extension 29 and the heat dissipater 30, respectively, and engaging a protrusion 31 formed on the case 12 in the holes 29a and 30a. The extension 29 thus comes into tight contact with the heat dissipater 30 and is fixed thereto. The heat dissipater 30 is made of a good thermally conductive material, such as copper, and formed separately from the lead frame 23.

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.

The light-shielding wall may remove the stray light which is the light that is obliquely incident on a lens, passes through the lens array plate in a thickness direction thereof, and outgoes from the neighbored lenses.

Abstract: Spherical convex micro-lenses are arranged between rectangular grooves adjacent to each other of a lens plate. The arrangement of convex micro-lenses is made to be in parallel with the short-side direction of the lens plate, namely, the direction of the rectangular grooves. Since stray light appears mainly on the convex micro-lenses arranged in the long-side direction of the lens plate, the stray light to appear in the long-side direction of the lens plate is removed by forming grooves at regular intervals in the long-side direction of the lens plate and forming a light absorbing film in each of the rectangular grooves. Or the stray light to appear in the long-side direction of the lens plate is removed by making the direction of arrangement of convex micro-lenses different from the long-side direction of the lens plate.

Abstract: A lens array 4 is formed as an erect 1:1 imaging lens by superimposing two lens plates 40 and 40 together. Each lens plate 40 consists of a number of micro lenses 41 which are regularly provided at a predetermined pitch and in a two-dimensional manner. This lens plate 40 is for example made by press molding the ultraviolet curing resin in a soft condition using a transparent mold and by irradiating the ultraviolet light on the ultraviolet curing resin from outside for hardening. Since the lens array 4 is provided with micro lenses 41 in rows in a sub-scanning direction, deterioration of an amount of light level resulting from the displacement between a light axis of the lens and an image sensor 6 is not generated.
