Abstract

PURPOSE: To eliminate the re-reading when the reading is impossible by scanning the plural areas at one time when the bar code is read out and then the logic operation is given to the plural information thus obtained to select the assured information.
CONSTITUTION: The light given from linear light source 1 is irradiated in parallel to bar code 3 through lens 2. Code 3 shifts in a constant speed in the direction of arrow (a). Thus, the binary information of the bar codes corresponding to the C, D and E areas of the bar code are detected via photoelectric element 8, 9 and 10. The signals of three areas thus obtained are supplied to the 3-input majority decision logic to obtain the final output. As a result, an accurate reading is poosible even though the reading is impossible at one area or the misreading is given at one area.
