Abstract: Described is a scanner for reading an optical code which includes a light transmission system and an image acquisition system. The light transmission system projects light on a target. The image acquisition system receives light reflected from the target to generate an image of the target. The image acquisition system is arranged to receive the light reflected from the target at a plurality of angles so that, when specular reflection of the target is associated with a first of the plurality of angles, light from a second one of the plurality of angles is available to minimize image degradation associated with the specular reflection.

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: An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements within the scanning assembly. The optical assembly may be in modular form, mounted onto a common printed circuit board with a beam scanner.

Abstract: A terminal for and method of reading indicia employ a hand-held housing, a scanning initiator, a keyboard and a display. The housing has a main portion and a head portion, both having generally rectangular cross-sections. A scan module is mounted on a circuit board that extends through the housing portions. The module includes a base for supporting a light emitter, another circuit board overlying the base, an opening for a light beam from the emitter to pass, and a planar member orthogonal to the base. A sensor having a field of view is mounted on the module. A drive scans the light beam and/or the field of view to read the indicia.

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 single flexural assembly for oscillating movement. The flexural assembly includes a flexure that lies in a plane extending through a central region of a scan mirror in a direction orthogonal to the plane of the mirror. 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: A scanning arrangement for use in an optical scanner, for example a bar code scanner, comprises an optical element which is mounted for oscillation in two directions to produce a two dimensional scanning pattern. The optical element is preferably relatively light, and is mounted for oscillatory motion in an x direction by the flexing of a spring of relatively high modulus of elasticity. The spring is secured to a mounting bracket which itself is mounted to a stationary frame by a further spring which is arranged to flex and cause oscillation in the y direction. The mounting bracket is relatively heavy in comparison with the mirror, and the second spring has a relatively low modulus of elasticity, thereby producing a y oscillation which is slower than the x oscillation.
