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 repetitive reciprocating movement either about an axis or in a plane to effect scanning.

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 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: A scan board module includes a printed circuit board on which optical and scanning components are mounted in an optically-aligned relationship. The module is mountable in hand-held heads and protected from damage due to external shock by shock mounts, or in workstations which are either directly or indirectly connected to a cash register-type terminal or hand-held terminal.

Abstract: The present invention relates to a bar code symbol scanning systems. The bar code scanning system is comprised of a laser, optical and sensor components. In the present invention a mirrorless scanner arrangement mounts one or more of these components on a drive for repetitive reciprocating movement either about an axis or in a plane to effect scanning. A photodetector can also be moved in a reciprocating motion. In another embodiment, the photodetector is fixed and a light receiving lens is moved in a reciprocating motion to focus a received light beam on the fixed photodetector. In yet another embodiment received light merely falls onto the surface of a fixed photodetector.
