| 20090034296 | Light Emitting Unit, Illumination Device Using Such Light Emitting Unit, and Image Scanner - A light emitting unit comprises a light emitting element, a light emitting element substrate for mounting the light emitting element, a light emitting element substrate frame member provided with a window for exposing the light emitting element, and an electrode for supplying electricity to the light emitting element, wherein the light emitting element substrate is a metal and the light emitting element is mounted directly on the light emitting element substrate. The light emitting unit is also characterized in that the light emitting element substrate is a metal, a metal oxide film is provided on the light emitting element substrate, and the light emitting element is mounted on the electrode formed on the metal oxide film. | 02-05-2009 |
| 20090073715 | Light Emitting Unit and Illumination Device and Image Scanner Using Such Light Emitting Unit - A light emitting unit comprises a light emitting element, a light emitting element substrate for mounting the light emitting element, and a light emitting element substrate frame member provided with a window for exposing the light emitting element, wherein the inside of the window is sealed with a first resin and a second resin, the ratio of the second resin relative to the first resin becomes smaller toward the outside of the window from the inside thereof. The first resin is a transparent resin, and the second resin is a colored resin with a high color value or a resin including a light reflective material and/or a light scattering material. Since a sectional border line between the first resin and the second resin is a curved line, the light reflected from the bottom section of the window among the light emitted from the light emitting element can also be efficiently emitted to the outside. | 03-19-2009 |
| 20090111048 | ALKALI-DEVELOPABLE BLACK PHOTOSENSITIVE RESIN COMPOSITION FOR FORMING LIGHT-SHIELDING BARRIER WALL - An alkali-developable black photosensitive resin composition for forming a light-shielding barrier wall which comprises, as indispensable components, (A) a carboxyl group-containing photosensitive prepolymer, (B) a photopolymerization initiator, (C) a black pigment, and (D) light-transmitting fine particles. By the use of this composition, light-shielding barrier walls ( | 04-30-2009 |
| 20090168126 | Light Emitting Unit, Lighting Apparatus and Image Reading Apparatus - 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 | 07-02-2009 |
| 20090218525 | Light guide and image reader - A rod-shaped light guide which does not cause unevenness in color at the portion near an incident face is produced by injection-molding transparent resin such as acryl and its surfaces include a light-emitting surface, a bottom face, left and right sides and end faces. One end face opposes a light emitting unit, and light scattering patterns for scattering light incident from the end face are formed on the bottom face. The light scattering patterns are different in shape between a portion near the end face as the incident face and a portion away from the end face. The light scattering patterns formed at the portion near the incident face are composed of a large number of fine hemispherical concaves, whereas the light scattering patterns at the portion away from the incident face are composed of triangular grooves or half cylindrical grooves, and the axial direction of these triangular grooves or half cylindrical grooves is equal to coincides with the width direction (sub-scanning direction) of the bottom face on which the patterns are formed. | 09-03-2009 |

| 20100014062 | LENS ARRAY PLATE OF ERECTING UNIT MAGNIFICATION SYSTEM, IMAGE READING APPARATUS AND IMAGE WRITING APPARATUS USING THE LENS ARRAY PLATE, AS WELL AS METHOD FOR MANUFACTURING THE LENS ARRAY PLATE - A lens array plate of long-size or large area is provided reducing deterioration of optical performance. A lengthy lens array plate ( | 01-21-2010 |
| 20100128353 | IMAGING OPTICAL SYSTEM, IMAGE READING APPARATUS AND IMAGE READING APPARATUS USING THE IMAGING OPTICAL SYSTEM - 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. | 05-27-2010 |
