Abstract: A portable scanning head emits and receives light from a light-emitting diode (10) to read symbols, such as bar-code symbols. The optics (12,18) within the scanner are operative for focusing a light beam (11) and the view of a light sensor (17) in different planes (13,22) exteriorly of a scanner housing. Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED (10) as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode (17) "sees" only that portion of the scan spot visible through the viewing window.

Abstract: In bar code symbol scanning systems employing laser, optical and sensor components, a mirrorless scanner arrangement mounts one or more of these components on a drive for repetitively reciprocating movement either about an axis or in a plane to effect scanning. All of the components are mounted together in a common assembly to constitute a compact, lightweight scan module which is mounted in an interchangeable, modular manner in housings of different configurations.

Abstract: A light scanning system, for example for a bar code reader, provides a scan pattern of intersecting lines by means of a scanning system having at least one rotating mirror (176,210), and a plurality of fixed angled mirrors (180,182,184) which are spaced around the axis of rotation of the rotating mirror.
