Abstract: An image scanning device is provided which includes a system for determining the distance to a target to be scanned. The image scanning device includes an optical system and an image sensor array for focusing a light beam and imaging the target. The device preferably includes an automatic focusing system for adjusting the position of the optical system in order to adjust the focal point, and thereby focus the image of the target onto the image sensor array. In one embodiment of the image scanning device, the distance is determined by analyzing a collimated aiming pattern formed by collimating the light beam. In another embodiment, the distance is determined by analyzing a speckle pattern caused by the speckle effect upon the light beam hitting the target.

Abstract: Actuator systems are provided for automatically focusing an optical image reader. Techniques are also provided which are applicable to the design of imaging engines and imaging lens systems associated with image readers of various types. More specifically, the present invention relates to lens guidance assemblies and actuator systems for automatically focusing an objective lens associated with an imaging system of an optical image reader. The optical image reader is preferably an optical code image reader for imaging optical codes, such as bar codes.

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: 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: 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 repetitively reciprocating movement either about an axis or in a plane to effect scanning. All of the components are mounted together in a common assembly to constitute a compact, lightweight scan module which is mounted in an interchangeable, modular manner in housings of different configurations.

Abstract: A bioptics bar code reader has first (1) and second (2) windows disposed at an angle to each other, a first imager (3) for the first window (1) and a second imager (4) for the second window (2) and first and second optics for directing light from a bar code in a reading area between the windows to the first and second imagers. The two imagers each obtain an image of the bar code in the reading area.
