Abstract
PURPOSE: To increase the reading efficiency by analyzing the module number of the bar based on the width of the bar scanned just before the relevant bar when the scanning is carried out by applying the hand scanner to the bar code symbol.
CONSTITUTION: The hand scanner 2 is operated manually on the bar code symbol 1 which is coded in combination of the bars having the different colors. Thus the optical signal changing in the lapse of time is received 4 and then converted into the electric signal. And this electric signal is analyzed by the analyzer 5. In this case, the module number of the bar when the scanning is carried out by applying the scanner 2 to the symbol 1 is analyzed based on the width of the bar scanned just before the relevant bar. As a result, a compact and lightweight structure is realized for the analyzer, at the same time reducing the effect of the fluctuation of the scanning velocity and thus increasing the reading efficiency.
