Abstract
Together with the Delta Distance Method, barcode data can be correctly read by converting to a digital signal an optical signal scattered from a barcode. Two types of toggle signals are generated every time the digital signal changes from high potential to low potential or vice versa and other toggle signals opposite to said toggle signals. The width of said 4 types of toggle signals are counted and various signals are detected necessary to read barcode data in use of said count signals.
