Abstract:
Provided is an illumination apparatus that applies light to an original, the illumination apparatus including: a light source; and a rod-shaped light guide including: an incident surface that receives the light from the light source; a reflection surface provided with a diffusion portion that diffuses the light incident on the incident surface; and an emission surface that emits, to the original, the light diffused by the diffusion portion. An area of the light guide is reduced by an inclination of the light guide from the incident surface side to a middle part in a longitudinal direction of the light guide, and the light guide is provided with the diffusion portion from the incident surface side to the middle part on the reflection surface.

Abstract:
An image sensor unit includes: a plurality of sensor substrates that are connected in a main-scan direction and that are provided with sensor chips in the main-scan direction, the sensor chips converting light from an original to electric signals; and a plurality of rod-lens arrays that are connected in the main-scan direction and that are provided with a plurality of rod lenses in the main-scan direction, the rod lenses focusing the light from the original on the sensor chips, wherein connection positions between the plurality of sensor substrates are arranged at positions not overlapping with connection positions between the plurality of rod-lens arrays. A decrease in reading accuracy of an image can be reduced even if short constituent members are connected in the main-scan direction to form an elongated image sensor unit.
Abstract:
There is provided with a method of manufacturing a resin article having a plating layer. A portion of a surface of a resin article is selectively irradiated with ultraviolet rays. The resin article irradiated with ultraviolet rays is treated using an alkaline solution. An electroless plating catalyst is applied to the surface of the resin article treated using the alkaline solution. A plating layer is selectively deposited on a portion of the surface of the resin article that is not irradiated with ultraviolet rays by submerging the resin article applied with the electroless plating catalyst in an electroless plating solution.
Abstract:
A substrate member includes a substrate and a plurality of chip regions formed on the substrate across a scribe line. Each of the plurality of chip regions includes a first region that has contact with the scribe line and in which a plurality of first pattern elements are formed, and a second region that is surrounded by the first region and in which a plurality of second pattern elements are formed. A minimum value of a size of the first pattern elements is greater than a minimum value of a size of the second pattern elements and/or a minimum value of an interval between adjacent first pattern elements is greater than a minimum value of an interval between adjacent second pattern elements.
Abstract:
A flexible circuit board 3a for mounting a light emitting element has base films 31a and 31b, a wiring pattern 32 formed on a surface of the base films 31a and 31b, and the cover films 33a and 33b that covers the base films 31a and 31b and the wiring pattern 32. At least one of the base film and the cover films 33a and 33b have a substrate 331 and 331a comprising a metal. The cover film 33a and 33b have such surface properties as to produce specular reflection or diffuse reflection of light or has substantially white reflecting films 36 and 333 on a surface of the cover film.
Abstract:
A flexible circuit board includes a base film formed by a metallic material, a first protective film formed on a first surface of the base film, and a circuit pattern adhered to the first protective film through an adhesive film. Projections and recesses for heat release are formed on a second surface that is a surface on the opposite side of the first surface of the base film.
Abstract:
Illumination apparatuses include: light sources; and light guides formed in a rod shape, wherein end surfaces in a longitudinal direction are incident surfaces that receive light emitted from the light sources. Diffusing patterns are formed on the light guides, and intervals between the diffusing patterns closer to the incident surface in a first area close to the incident surface are smaller than intervals between the diffusing patterns closer to the incident surface in a second area farther from the incident surface than the first area.
Abstract:
A first light source and a second light source are arranged so that a protrusion direction of a first terminal from a first supporting body and a protrusion direction of a second terminal from a second supporting body are different when viewed in the longitudinal direction of a light guide. The first light source and the second light source are arranged so as to reduce a protrusion direction of the first supporting body and the second supporting body in a predetermined direction from an area where the first light source and the second light source overlap when viewed in the longitudinal direction of the light guide.
