Japanese Patent JP2727037
Kind Code:
B2
Abstract:
A bar code reader employs plural scanners for scanning a bar code mark with respective, plural optical scanning beams, counters connected with the scanners respectively producing numerical data representing the widths of corresponding black and white bars of the bar code. A composer selects the numerical data from the scanners so as to produce composed numerical data, and a decoder decodes the composed numerical data and produces a bar code data signal output. The composer, upon detecting a false data such as an overflow error data or waveform error data present in the respective numerical data output of a first selected scanner, switches therefrom to the respective numerical data output of a second scanner.
