摘要： A system for synchronization of the angular position of a rotating optical assembly in a bar code scanner having a rotating optical assembly. The optical assembly is rotated by a motor which produces a fixed number of pulses per rotation, the pulses occurring at equal intervals such that each pulse indicates a degree of angular rotation of the motor. The pulses are continuously monitored and counted. Timing is simultaneously monitored. A synchronization label is placed in the scanner such that light directed through the rotating optical assembly will strike the synchronization label and be reflected back to the rotating optical assembly when the rotating optical assembly is at a particular angular position, thus establishing an initial angular position of the rotating optical assembly. Once the initial angular position is established, timing is continuously monitored and pulses are continuously monitored and counted. When an event of interest, such as bar code scan occurs, the pulse count is evaluated and processed to determine an angular position of the rotating optical assembly with respect to the initial position as established at synchronization.

摘要： An attenuator for varying the power of a laser scanning light beam includes a bracket having a reduced portion intermediate its ends enabling one end to be rotated around its other end. A glass element is secured to the movable end and is moved to a position which intercepts the laser light beam at an angle of incidence which varies in accordance with the amount of rotation of the movable end around the other end.

摘要： The useful life of a laser, such as a laser diode, is extended by causing the laser to operate only intermittently when continuous operation is not required. When such a laser diode is used in a scanner for scanning coded symbols, such as bar codes, in merchandise check-out operations, continuous operation is required only when a coded symbol is present in a target area. A sensing device is provided for sensing the transitions in light reflected back from the target area, and a counter is provided for counting the number of such transitions. Since a much larger number of transitions are sensed and counted when a coded symbol is being read than when no such symbol is present in the target area, this difference in number of transitions is used to distinguish between the two conditions and to cause the laser diode to be turned on for continuous operation only when a coded symbol is present in the target area to be read.

摘要： A compact optical scanning system comprises a portable enclosure structure having a cover portion which includes a glass enclosed aperture over which a UPC label attached to a purchased merchandise item is moved. Mounted within the enclosure is a laser whose output coherent light beam is reflected along a path extending in a direction parallel to the cover portion by mirrors and a bifocal lens member mounted on a shelf extending between opposite sidewalls of enclosure. One of the mirrors mounted on the shelf reflects the laser beam in a downward direction at a rotating multifaceted mirrored member mounted on and directly beneath the shelf and the bifocal lens. The rotating mirrored spinner directs the laser beam at a plurality of pattern mirrors which redirects the received laser beam towards the aperture, forming a scan pattern thereat for scanning the UPC label.
