Abstract: 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.

Abstract: A scanner includes an illuminator and a platen adapted to support a document to be scanned. A light source directs light into the platen and the light is reflected internally within the platen. A movable light sensor is positioned adjacent the platen. Liquid crystal sections between the document and the light sensor cause a zone of light to pass from the platen to the document, thereby illuminating only a portion of the document.

Abstract: 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.
