Abstract: A dynamic omni-directional scan pattern is generated in an electro-optical reader for reading indicia by oscillating a mirror located between a light source and a rotating mirrored component. Light from the mirror is reflected off the rotating component and swept across a plurality of stationary mirrors for reflection therefrom through a window of the reader.

Abstract: A bar code reader has an integrated scanning component module which is mountable on a printed circuit board. In one embodiment, the module may include the digitizer/decoder electronics, enabling the module to be used with a generic PCB. In some embodiments, the module includes a high speed optical scanning arrangement having an optical element which extends longitudinally of a flexible member, secured at one end. In other embodiments, the invention extends to a hand-held optical scanner having a scanning assembly, detector and data transmission coupling all mounted to a common printed circuit board, preferably located within a manually-graspable handle. In yet a further embodiment, an abuse-detector or accelerometer is provided for determining when the device is exposed to deceleration above a predetermined limit, and optionally for automatically shutting down applications programs and for providing a black-box-record of a short time frame before the device was exposed to an unexpected shock. Preferably, the reader is shock protected by a thermo-plastic elastomer housing section. An outgoing light beam is directed at a non-orthogonal angle relative to the PCB.

Abstract: A flexible member mounts a scanner component for angular oscillating movement relative to a support about an axis in alternate circumferential directions between scan end positions. The scanner component is electromagnetically driven in order to scan a light beam across optically encoded indicia to be read. A permanent magnet is connected to the scanner component and magnetically interacts with an electromagnetic coil so as to impart a force to the magnet and move the scanner component from a rest position to at least one of the scan end positions.

Abstract: An optical scanning module has a metal base, a first circuit board mounted across one end of the metal base and a second circuit board mounted orthogonal to the first circuit board. The metal base supports a light emitter for producing a scanning beam and serves as a heat sink for the emitter. A flexible support attached to the metal base supports a mirror for oscillating motion. The module includes a drive mechanism, typically in the form of a permanent magnet and electromagnet, for producing reciprocal motion of the mirror. A detector included in the module senses light reflected from an indicia scanned by the beam. A flexible electrical cable connects the circuitry on the first and second circuit boards so that circuitry operates together to produce all signals necessary for operation of the scanner module and to process the electrical signals from the detector. Preferred embodiments include a flexible support consisting of a planar spring located between the mirror and one of the magnets. The components of the module are dimensioned so that the weight of the magnet balances that of the mirror. The invention also encompasses systems for scanning the beam simultaneously in two orthogonal directions at two different frequencies. This bi-directional scanning can produce a raster scan pattern for reading two-dimensional bar codes, or this scanning can produce a moving zig-zag pattern for reading truncated bar codes.

Abstract: High speed scanning arrangements in scanners for reading bar code symbols by oscillating a scanner component in a single line pattern, the scanner assembly being suspended from a flexural assembly for oscillating movement. A drive is operative for moving the scanner assembly from a rest position in a circumferential direction to one of two scan end positions. The flexural assembly is tensioned and stores energy, which energy is released in order to return the scanner assembly in the other circumferential direction to the other scan end position.

Abstract: An optical scanner such as a bar code scanner includes a segmented fold mirror, the individual sections of which have different profiles. By directing the scanning laser beam across the fold mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.
