20090003016 | Light Guide, Lighting Device and Image Reading Device - To provide a rod-like light guide and a line lighting device including the rod-like light guide, both of which are easy to include in an image reading device, a contact-type image sensor and an image reading device. For instance, a protruding portion having a flat or curved surface is formed by grinding an end face of a rod-like light guide in a longitudinal direction while leaving at least 80% of the surface area of the end face, and a reflective surface is formed by bonding a heat transfer film to the protruding portion. Thus, even if a portion of the protrusion portion melts when performing thermal processing on the heat transfer film, the portion will not jut out beyond a cross-sectional area of the rod-like light guide, and the rod-like light guide can be easily contained in a case. | 01-01-2009 |
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 |
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 |
20090294630 | IMAGE SENSOR, IMAGE READING DEVICE AND PRODUCTION METHOD OF IMAGE SENSOR - An image sensor and a manufacturing method thereof are provided, so that the warp or the distortion is not caused even if there is the thermal expansion difference or the thermal contraction difference in the longitudinal direction between the linear illuminating device and the frame. The image sensor comprises a linear illuminating device for illuminating an original; a light-receiving element array for receiving reflected light from the original; a lens array for focusing the original on the light-receiving element array; a frame for containing the linear illuminating device, the lens array, and the light-receiving element array; and a resilient retaining portion for pressing the linear illuminating device, which is mounted in the frame, into the frame. | 12-03-2009 |
