摘要： A scanning apparatus includes an illuminator for illuminating a portion of a document to be scanned. The illuminator includes an array of discrete light sources and an optical element. The optical element includes a light-transmissive material and defines a focusing portion and an angular modification portion. The angular modification portion tends to reduce specular flare by modifying the angular distribution of light from the light sources which are within the acceptance angle of a lens arrangement which focuses light from the document onto a sensor.

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： 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.
