Abstract
The intensity of light reflected from a bar code constructed by bars and spaces is time-sequentially detected by use of a line sensor, sample-and-hold circuit and binary-coding circuit. Data representing the time-series of bars and spaces is counted by a white/black variation point detector and bar/space width counter and converted into width information. In this case, the bar/space width counter starts the counting operation in response to a count enable signal output after a skip-reading counter has counted a count amount previously set by a skip-reading amount setting section. Thus, when width information is stored into a memory, data obtained after data of the preset width among the width information is stored into the memory.
