Abstract

PURPOSE: To make it possible to attain bar code display with high recording density and low rate of error read by making constant the width of the dark part of a bar code and by displaying information by the rate between the width of the light part and that of the dark part.
CONSTITUTION: Widths W40, W41...W47 of dark parts 40, 41...47 are all equal; and, for example, light parts 50, 53, 55, 56, and 57 narrow in width express "0", and light parts 51, 52 and 54 wide in width express "1". In this case, rate R of the width of a light part to that of the dark part right before it is set between, for example, 0.9 and 1.1 as to "0" or 1.8 and 2.2 as to "1", so that even if the scanning speed is changed by about 10% at its maximum, it can be made possible to read codes. Consequently, the display of high-density and low-error-read-rate bar codes can be achieved
