Abstract
A barcode scanner includes a spinner disposed in optical alignment with a light emitter for reflecting a light beam from a plurality of mirror facets. A motor is joined to the spinner for rotating the spinner to align in turn the spinner facets with the light emitter. A plurality of pattern mirrors are optically aligned with the spinner for reflecting the light beam from the spinner facets as a plurality of scan lines. A controller is operatively joined to the light emitter for turning the light emitter on during a first mode of operation for effecting all of the plurality of scan lines in sequence. A control tab is joined to the spinner for rotation therewith. A sensor is spaced adjacent to the spinner for detecting proximity of the control tab, and is operatively joined to the light emitter for periodically turning on the light emitter during a second mode of operation for effecting less than all the scan lines corresponding with detection of the control tab adjacent to the sensor.
