Abstract: An arrangement for and a method of reading bar code symbols on a target to move a light beam emitted by a light source in a multiple line, scan pattern during a scan period in a first operational mode. Upon selection of a second operational mode by a user, a controller intermittently operates and energizes the light source to emit the light beam for a working time period which is less than, and a fraction of, the scan period to generate a single scan line across the symbol.

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: A compact assembly for electro-optically scanning indicia includes an oscillatable component operative for focusing, and for sweeping, a light beam across the indicia and, optionally, for correcting for scan aberration. A laser diode for emitting the beam is inserted into a central opening surrounded by an electromagnetic coil to conserve space. A magnet on the component interacts with the coil to effect oscillation. A floating flexure returns the component to an equilibrium position.

Abstract: A retroreflective optical scan module, including first and second selectable light sources having different beam characteristics for directing a selected light beam to a symbol to be read, an optical assembly including a light collecting portion which collects and redirects the light reflected from the symbol along an optical path to a sensor, and a selector for selecting which light source to use depending on whether a one-dimensional or a two-dimensional symbol is being scanned.

The reflector is advantageously mounted for oscillation on a pair of taut elements constituting an endless band.

A manually operable switch is disposed from one mode of use to the other, and also functions to move an appropriate focusing optical element in and out of the beam path.

Abstract: A unitary body of optical material and associated methods for reading indicia such as bar codes is provided. The unitary body can focus light from a light source into a beam, redirect light reflected from a target to a photodetector, and provide mechanical support for a light source, printed circuit board, or other indicia reader components. In comparison to conventional apparatus, the unitary body requires a reduced number of components and is therefore easier and less expensive to manufacture and assemble. The unitary design increases reliability and performance consistency while decreasing sensitivity to thermal and mechanical loading. Moreover, the unitary body reduces the overall tolerance budget of a reader and therefore facilitates mass production of optical apparatus and readers. The unitary body and associated methods may be implemented in a compact reader with the aforementioned advantages in the form of a pen, or can be integrated into an antenna of a wireless device, such as a cell phone or a PDA.
