Abstract:
The present invention relates to photosensitive chips for creating electrical signals from an original image, as would be found for example in a digital scanner, copier, facsimile machine, or other document generating or reproducing device. More specifically, the present invention relates to preferably providing a supplemental chip in each abutment region to enhance image quality.
Abstract:
A method of producing an optical device, includes the steps of forming a space between an optical member and a first mold and a second mold by arranging the optical member between the first mold and the second mold, at least either the first or second mold is arranged to touch one surface of the optical member. A resin member is injected through an injection port provided with the first or second mold in the formed space.
Abstract:
A photoelectric converting device having a guide member includes a plurality of photoelectric converting elements disposed to confront an original sheet the image information of which is to be read; a protection layer disposed on the photoelectric converting elements; a light transmissive substrate on which the photoelectric converting elements are disposed; and a flexible guide member disposed on the original-sheet supply side of the light transmissive substrate, the guide member being disposed in such a manner that at least a portion of the guide is positioned in contact with the edge surface of the light transmissive substrate.
Abstract:
A solid state imaging device has solid-state imaging-device chips each having a picture-element array and bonding pads, chip carriers each having long sides longer than the solid-state imaging-device chip and terminals electrically connected to corresponding bonding pads on the chip, a package board which carries the chip carriers, and external leads provided on the package board and electrically connected to the respective terminals of the chip carriers. In a method of assembling such a solid state imaging device, a plurality of solid-state imaging-device chips are mounted on respective chip carriers, and a plurality of imaging units are formed by electrically connecting the terminals of each chip carrier to the corresponding bonding pads. The imaging units are then arranged on the package board and the terminals of the imaging units are connected to the external leads, respectively. A test is conducted on the solid-state imaging-device chips of each imaging unit, and if a non-conforming chip is found, an imaging unit including the non-conforming chip is removed from the package board and a new imaging unit is secured to the package board in place of the removed chip.
Abstract:
A mathematical method for selecting the shape for an occluding aperture which is to be positioned at a predetermined aperture location in a light path extending between an illuminated line object and a linear photosensor array. Through use of the aperture selected according to the method, a light intensity measurement is obtained across the linear photosensor array which is uniformly proportional to the light intensity across the illuminated line object.
Abstract:
A light emission element array comprises a substrate, a plurality of light emission elements such as light emitting diodes aranged linearly in a row on the substrate and a rod like, i.e., columnar, light converging lens unit arranged above the light emission element row in parallel thereto and adapted to diffuse and simultaneously converge the transmitted light. The light emitting surface of the light converging lens unit is made rough by a chemical treatment, blast treatment or other means.
Abstract:
An image sensor which does not produce stress in a line illuminating device or a frame and therefore is free from warping or the like even when thermal expansion difference or thermal contraction difference exists between the line illuminating device and the frame, and a production method of the image sensor. The image sensor comprises a line illuminating device for applying light to an original copy, an light reception element array for receiving light reflected from the original copy thus illuminated, an lens array for imaging the original copy and the light reception element array, a frame housing the line illuminating device, the lens array and the light reception element array, and a resilient holding unit mounted on the frame, for pressing the line illuminating device against the frame.
