    摘要： A system for detecting reflectance from an image bearing surface in a printer or electronic copier includes an illuminator array, positioned adjacent to the image bearing surface, comprising a plurality of discrete illuminator elements that are spaced in a linear arrangement; a light diffuser positioned between the illuminator array and the image bearing surface, the light diffuser being positioned with respect to the illuminator array to receive the light beams emitted by the illuminator elements and to diffuse the light beams for transmission to the image bearing surface at an incidence angle; and a linear sensor array positioned adjacent to the image bearing surface such that specular and diffuse portions of the light beams reflecting off the image bearing surface at a reflectance angle bearing are received by the sensors.

    摘要： A document illuminator comprising a light-transmissive element having an embedded side emitting LED fitted in a cavity formed therein. The light-transmissive element is formed with one or more optical notches and is totally encased in a white surround to yield total internal reflection of the light rays emanating from the LED. The reflected light rays are collected at an aperture which in turn transmits high power and highly uniform illumination profile to illuminate a document.

    摘要： An apparatus for scanning a document comprises a platen for supporting at least a portion of the document; a light source; and an optical element for directing light from the light source to the platen. The optical element defines a plurality of small planar surfaces, the small planar surfaces being arranged in a linear array. Light emanating from a source is reflected from one of the small planar surfaces and emerges substantially perpendicular to an exit surface.

    摘要： Image sensor module architecture provides flexible mounting of illuminators in an imaging apparatus with flexible fasteners. The architecture involves one or more LED-based illuminators that may be mounted adjustably to provide high intensity and uniform profile luminescence. The supporting imaging and electronic circuit components are quickly assembled and disassembled from the image sensor module by using a flexible multi-function clip having multiple segments for holding multiple objects together.

    摘要： A document illuminator includes a light-transmissive element having an embedded source of illumination fitted in a cavity formed therein. The light-transmissive element preferably has one or more optical notches and preferably is encased in an opaque surround to promote total internal reflection of the light rays emanating from the LED. The one or more optical notches may include a dual-V notch or an elliptical notch. The reflected light rays are collected at an aperture which in turn transmit light at high power and highly uniform illumination profile to illuminate a document.

    摘要： A light-transmissive constant velocity transport platen. A light source is an integral part of the light-transmissive platen forming a light guide illuminator. The constant velocity transport integrated illuminator uses total internal reflection within the light-transmissive platen as well as frustrated total internal reflection at extraction surfaces to direct light out from an aperture to a document translated by a constant velocity transport system. For point light source, the system uses a deflector to avoid hot spots in the illumination profile. The deflector is no longer needed when line source is used in the constant velocity transport integrated illuminator.
