Abstract:
In an image reading apparatus incorporating a CIS unit warped by heat shrinkage of a thermoplastic resin molded product, the optical distances from a read line to a photoelectric conversion element in the center and the two end portions in the longitudinal direction of the photoelectric conversion element are different. A thermally caulked combined structure is obtained by fixing an object to be fixed by thermal caulking by thermally deforming a plurality of caulking projections formed in the longitudinal direction of a molded product made of a thermoplastic resin and having a rectangular parallelepiped outer shape. Antiwarping grooves (15) are formed apart from the proximal portion of each caulking projection (12) of the molded product (4) before thermal caulking so as to sandwich the projection.

A white light emitting apparatus (20) is provided with a first white light emitting diode (11) that emits yellowish white and a second white light emitting diode (12) that emits bluish white in the same direction of the light emitted from the first white light emitting diode (11). The white light emitting apparatus (20) is further provided with a current control circuit that controls drive currents of the first and second white light emitting diodes (11, 12).
Abstract:
The invention alters the light emission proportion of each of five LEDs for each of a plurality of accumulation cycles in a main scanning direction, in accordance with light emission conditions that are configured in the lighting condition register, causes the emission spectra of the multicolored illumination that composites the light emitted from the five LEDs to approximate three types of color-matching functions that are represented with CIEXYZ or other standard color space, and thus, use a sensor to convert the light that is illuminated by the five LEDs onto an original, and reflected therefrom, into an electrical signal.

A color image sensor which uses a sensor array that has, as a lighting light source, 3-color light emitting elements capable of independently controlling light emitting timings respectively and at least three pixel arrays respectively constituted by a plurality of pixels, respective pixel arrays being comprising color filters having different transmitting wavelength regions from each other, and which independently controls the lighting start and lighting period of each light emitting element, whereby it is possible to prevent color misalignment in an output image signal and regulate the image signal level of each color component.
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).
Abstract:
There is provided with a method of manufacturing an electrostatic adsorptive belt. A portion for forming an electrode pattern on a first resin layer is irradiated with an ultraviolet laser beam. A region including the portion for forming the electrode pattern on the first resin layer is oxidated. The electrode pattern if formed on the first region layer by plating. A second resin layer is formed on a surface of the first resin layer on which the electrode pattern is formed.
Abstract:
An illumination apparatus includes: a light source that emits light at a plurality of wavelengths; and a rod-like light guide that shapes light emitted by the light source into a line, wherein the light guide is made of a material including a region in which transmittance of wavelengths is not constant, the light source is arranged at one end of the light guide in a longitudinal direction, the light source includes a wavelength of a region in which transmittance of the light guide is not constant, and a reflection surface including reflection member having reflectance differences for the light at a plurality of wavelengths is formed at the other end of the light guide in the longitudinal direction.
Abstract:
A contact image sensor unit includes: a light source (10) illuminating an original; a rod-like light guide (11) guiding light from the light source to the original; an imaging element (12) forming reflected light from the original on a plurality of photoelectric conversion elements; a sensor substrate (14) on which the plurality of photoelectric conversion elements are mounted; a frame (15) to which they are attached and which has a positioning part (200) for attaching the light guide (11) thereto; and a supporting member (16) which attachably/detachably supports the light guide (11) and is attachably/detachably attached to the positioning part (200). Since the light guide (11) can be attached to the frame (15) without using an adhesive, the deformation of the light guide (11), the warpage of the contact image sensor unit and so on can be prevented.
