    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: An apparatus for illuminating a document includes an optical element formed of a light-transmissive material of a predetermined refractory index that defines a curved entry surface and an exit surface opposite the entry surface in which light enters the optical element via the entry surface and light exits the optical element via exit surface. A first substantially parabolic surface is defined between a first edge of the entry surface and first edge of the exit surface and a second substantially parabolic surface is defined between a second edge of the entry surface and a second edge of the exit surface such that the first and second substantially parabolic surface are spaced apart more at the exit surface than at the entry surface.

    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 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 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.
