ABSTRACT:
A feedback system for an optical scanner which provides scanning rate information to an operator during scanning. The feedback system includes a controller for determining scanning rate information during scanning, and a plurality of lights controlled by the controller which provide the scanning rate information to an operator during scanning. The system also includes a shift register coupled between the controller and the indicator lights, and a speaker for providing an aural indication of successful and unsuccessful scanning events during scanning. The number of lights turned on during scanning is directly related to the scanning rate. The indicator lights may also provide information about the maximum scanning rate. The indicator lights are preferably arranged in a line on a side of the scanning window opposite the operator, but could be located anywhere on or in the vicinity of the scanner.
