Abstract: An optical scanning system for reading indicia of differing light reflectivity has an optical scan module including a light emitter for emitting light onto the indicia and a light detector for detecting the reflection of light from the indicia. The scan module is adapted to be mounted on at least one finger of a user. A first peripheral module has a receiver for receiving a first signal corresponding to the detected reflection of light from the optical scan module. The first peripheral module is adapted to be mounted on an arm or wrist of the user. A second peripheral module includes a receiver for receiving a second signal corresponding to the first signal from the first peripheral module by radio frequency transmission. According to other aspects of the invention, the light detector is located in a housing separate and apart from the optical scan module.

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 mirro r. 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: An optical scanner (30) has a scanner component mounted to a leaf spring (34) for oscillatory motion about an axis. An electromagnetic coil (58) and permanent magnet (56) cause a force to be applied to the scanner component away from a central, neutral position. Bending of the leaf spring provides a restoring force biasing the scanner component back towards the neutral position.

Abstract: To reduce the size and weight of an optical scanner, the present invention provides a mirrorless beam scanning unit. In some embodiments, the light emitter itself moves back and forth, and in other embodiments the objective lens reciprocates laterally in front of the light emitter. For example, a flexible support structure, such as one or more strips of mylar, movably mounts the objective lens in front of the light emitter. The objective lens is laterally reciprocated in response to a motive force, for example as might be applied by a combination of a permanent magnet coupled to the objective lens and a fixedly mounted electromagnet driven by an alternating current signal. Reciprocation of the objective lens during emission of light by the light emitter causes the light to scan a surface, such as a surface bearing a bar code label.
