Abstract
An automatic electronically triggered scanner includes photo sensing apparatus for reading bar code data and for decoding the bar code data and then ascertaining whether the bar code data is valid. Following the reading and decoding of a valid bar code, the further decoding of bar code data by the scanner is inhibited until a predetermined condition is met to ensure that the bar code just read (which provided valid data) is not re-read. For the predetermined condition to be met the scanner must sense the absence of potentially valid bar code data for a preset interval following the decoding of each set of valid data. Subseqent to the preset interval during which only invalid data is present the scanner is placed in a condition to process valid data.
