摘要： An optical system and method for data reading. The preferred system is directed to a scanner which includes a multiple beam service, such as a laser diode and a beam splitter which generates first optical beam and a second optical beam, the first optical beam being directed toward one side of a scanning optical element such as a rotating polygon mirror and to a first mirror array, the second optical beam is being simultaneously directed toward a second optical element such as another side of the rotating polygon mirror and then to a second and a third mirror array. The first mirror array is configured to generate a scan pattern through a vertical window and the second and third mirror arrays are configured to generate scan patterns passing through a horizontal window. In combination, the three mirror arrays generate three sets of scan lines so as to scan the bottom and all lateral sides of an object being passed through the scan volume.

摘要： An improved, rotatably articuable scanner for reading and decoding bar codes in connection with the sale of retail articles is disclosed. An ultra-compact, lightweight, low-cost, self-contained, visible laser diode (VLD) bar code scanner is provided with a great range of functionality and versatility. A scan head housing an optical subsystem is rotatably connected with a tower housing. The heat-generating electronic components are located in the tower housing away from heat-sensitive optical components located in the scan head. The scanner presents an extremely small footprint, and provides for its mounting in virtually any orientation and location. The optical subsystem uses a basket-type mirror array configured around a rotating planar folding mirror, driven by a compact cup (brushed) DC motor. The scanner features a short optical beam path. The organization of components within the scan head and tower housings, as well as the partitioning thereof between the two, provides for convection-cooled operation of the optical subsystem. The center of mass of components in the scan head is located near an axis of rotation of the scan head, thereby making the scanner extremely stable despite its small footprint. Ease of field maintenance and calibration of the optical subsystem is very simple because the replaceable components thereof are decoupled from the remaining components and replacement parts do not require optical alignment.

摘要： A method and apparatus for reading bar codes or other images while reducing or eliminating the need for self-generated illumination. An image reader is preferably embodied as a handheld unit and comprises an efficient optical collection system including an aperture with a high aspect ratio and/or a multi-focal lens or lenses. An optically transmissive spacer affixed to the front of the handheld unit allows ambient light to be collected at close range, and a diffuser may be used to reflect ambient light from the handheld unit to provide additional illumination at close range. A masked CCD detector with rectangular pixels receives collected light and is coupled to an adaptive exposure circuit for preventing saturation of the CCD detector at high illumination levels. A correlated double sampling circuit coupled to the adaptive exposure circuit rejects common mode noise and allows operation in lower light levels. The correlated double sampling circuit is connected to a signal processor which uses a derivative based technique for detecting edges of the image. A decoder uses the edge detection information to decode encoded information from the image.

摘要： An integrated data reader and electronic article surveillance (EAS) system, and methods of operation. In one configuration, a data reader such as a bar code scanner is equipped with an EAS deactivation module disposed behind the scanner surface preferably downstream and/or upstream of the scanner window. The system may be configured such that the EAS deactivation module is interchangeable from the right side of the scanner housing (which is preferred for left-to-right scanning motion) to the left side of the scanner housing (which is preferred for right-to-left scanning motion). In other configurations, the deactivation module may be disposed in the housing adjacent to the window and oriented longitudinally and parallel to the sweep direction of the item. The EAS deactivation modules have various configurations such as simple planar coils, a magnetically active core with coil windings, or two part L-shape construction.
