Abstract: An optical scanning module has orthogonally-mounted first and second circuit boards (416,418) which carry circuitry that operates together to produce the signals necessary for operation of the module, and to process electrical signals from a reflected light detector. In a preferred embodiment, scanning of the light beam is achieved by reflecting the beam from a mirror (159) which is mounted to a support (103) which itself is mounted for reciprocal oscillation on leaf springs (121,123). Oscillation is provided by the interaction of a permanent magnet (109) on the support (103), and a stationary electro-magnet (133). The invention also encompasses systems for scanning the beam simultaneously in two orthogonal directions, and for producing a moving zig-zag scanning pattern.

Abstract: The disclosure relates to systems and techniques for reading optical codes, and more particularly to code reading systems with plural imaging or scanning modules pointed in various directions toward a target volume, which increase the likelihood that a code symbol on an arbitrarily oriented object in the target volume will be read. Other aspects of the invention relate to use and configuration of hand held readers, docking devices, operator side rails, arched tunnels and mirrors for increasing the coverage of the system. Additional aspects of the invention relate to components associated with point of sale installations or code reading terminals including integrated scales, input pads, system controls and displays.

Abstract: Several optical systems for imaging engines of imaging optical code readers are disclosed. Each optical system includes the abilities to change the depth of field of the imaging field and to adjust a focus quality of the imaging field. The disclosed structures for changing the depth of field of the disclosed optical systems allow for the automatic or manual selection of one of a plurality of depths of field.

Abstract: An optical scan module, for example for in a bar code reader including a light source, 208 mounted on the base of the module and at least one fold mirror, 213,215, for reflecting and redirecting the scanning light beam along an optical path, 212,214,206, which is parallel to the base and over at least a portion of the top side surface of the module, so that the scanning beam is longer than the length of the side of the module which the scanning beam passes over enroute to the target. Focusing optics for collecting light reflected from the indicia comprises either an element configured such that its first surface receives the incoming light, and the second surface attenuates rays collected from the middle at the scan line relative to the rays collected from the ends or an element having a cross-section of a cosine function over one cycle. The sensor for detecting the reflected light has selectively activatable discrete 1 and 2 portions corresponding to the position of the spot beam on the target indicia.

Abstract: To read optically encoded information over a wide range of densities, the present invention provides a spacer system on the tip of an optical reader. The optical reader may be a contact wand type device, for example including a fixed laser emitter. Alternatively, the optical reader may be a moving spot scanner. In either case, the emitter element of the optical reader produces a diverging beam of light. During a reading operation, the spacer contacts the object surface on which optically encoded indicia is formed. The spacer selectively defines at least two different distances between the light emitter, or the focal point of the emitted beam of light, and the object surface. Because of the beam divergence, the diameter of the beam at its point of impact on the object surface will be different for each of the two different distances. The different beam diameters provide the optical reader with different effective sensing spots for reading different density symbols. The present invention also incorporates an optical reader, typically a moving spot laser scanner, into a number of different types of computer data input devices, such as the stylus of a digitizer table and a computer "mouse." In one such integrated terminal embodiment, the optical reader is combined with a touch sensitive display and data input device.

Abstract: A first module (10), including a laser for emitting a laser beam and a photodiode for detecting light reflected from a bar code symbol, is independently mounted on a support (14a) in a spaced relation to a second module (12) which includes a movable reflector and a drive for moving the reflector. The reflector is advantageously mounted for oscillation on a pair of taut elements constituting an endless band.

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 system for reading bar code symbols or the like, having a scanner for generating a laser beam directed toward a target and producing a narrow first raster scanning pattern that enables the user to manually aim and direct the beam to the location desired by the user and a relatively wider second raster scanning pattern that sweeps an entire symbol to be read, and a detector for receiving reflected light from such symbol to produce electrical signals corresponding to data represented by such symbol.
