Abstract:
An image sensor unit includes a light source that emits light, and a light guide that guides the light from the light source to an object to be illuminated. The light guide includes a linearly elongated rod-like rod portion provided with a light emission surface from which light is emitted to the object to be illuminated, and a curved portion which is integrally connected to an end in the longitudinal direction of the rod portion, includes a light entering surface where the light emitted from the light source is emitted on an end of a side opposite to the rod portion and in which the center line is curved. A reflection member that reflects light is provided to be in close contact with at least a part of a surface of the curved portion.
Abstract:
An image sensor unit (60) includes: a light source part (25) that emits at least ultraviolet light in a main-scan direction to an object to be illuminated; a light condenser (32) that focuses light from the object to be illuminated; an image sensor (75) that converts the light focused by the light condenser (32), into an electric signal; and an ultraviolet cut part (65) that is disposed between the object to be illuminated and the image sensor (75), cuts off ultraviolet light in light reflected by the object to be illuminated, and allows fluorescent light to transmit therethrough. The image sensor (75) includes an ultraviolet detection part (77) that detects light in the ultraviolet light emitted from the light source part (25), the detected light having been reflected by a reflecting part but having not transmitted through the ultraviolet cut part (65).

Provided is a conveying apparatus including a conveying unit that conveys a recording paper along a conveyance path, an imaging unit that images the recording paper to detect conveyance information on the recording paper, and a light source unit that emits light to the recording paper imaged by the imaging unit, wherein the light source unit has a shape of a rod elongated in a conveyance direction of the recording paper.
Abstract:
Provided is a control unit of a conveying apparatus, the conveying apparatus including: a conveying unit that conveys recording paper along a conveying path; and an imaging unit that images the recording paper and an object not conveyed by the conveying unit, wherein the control unit acquires actual conveyance information of the recording paper from image information of the recording paper imaged by the imaging unit and image information of the object imaged by the imaging unit.
Abstract:
An illumination apparatus includes a light source and an elongated light guide, wherein the light guide includes an emission surface that emits light from the light source and a reflection surface that reflects the light to the emission surface, the reflection surface includes a plurality of diffusion portions that diffuse the light, the diffusion portions have a shape of part of a sphere recessed from the reflection surface, a depth of the diffusion portions from the reflection surface is equal to or greater than 16.5% and equal to or smaller than 50% of a diameter of the sphere, and a width of the diffusion portions is equal to or greater than 0.1 mm and equal to or smaller than 50% of a width of the reflection surface.
Abstract:
An image sensor unit includes: a light source; a rod-shaped light guide; a light condenser that condenses light from an illuminated object; and a frame. The frame includes: a light guide housing chamber that houses the light guide; a light condenser housing chamber that houses the light condenser; and a partition wall provided between the light guide housing chamber and the light condenser housing chamber. The light guide includes: a light incident surface that receives light emitted by the light source; a light diffusing surface that diffuses the light entered from the light incident surface; and an abutment surface abutted to one side of the partition wall, which covers at least a part of the abutment surface of the light guide, where an incident angle to the abutment surface of the light directly reaching the abutment surface from the light diffusing surface is smaller than a critical angle.
Abstract:
An image sensor unit includes a light emitting element, a light guide that has a substantially rod-like shape and shapes light emitted by the light emitting element into a line, a light condenser that focuses light from an illuminated object, an image sensor that detects the light focused by the light condenser, and a frame in which a light guide housing chamber that houses the light guide and an image sensor housing chamber that houses the image sensor are formed. A correction optical path that extends from the light guide to the image sensor without passing through the light condenser is formed in the frame.
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:
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 irradiated with ultraviolet rays. A binding agent is applied to the surface of the resin article. The binding agent binds the resin article with an electroless plating catalyst. The resin article applied with the binding agent is washed using an alkaline solution. The electroless plating catalyst is applied to the surface of the resin article after the resin article was washed. The resin article applied with the electroless plating catalyst is submerged in an electroless plating solution.
