ABSTRACT:
An optical readable code employing dots, wherein dot files are divided into eight groups perpendicular to the course of printing so that each group that consists of a plurality of dot files is separated from the other parts by divisions, each of which consist of one or several dot files; dot ranks are divided similarly; and each part divided up in this way is regarded as one bit mark. The combination of printed and blank dots in each bit mark optically expresses the information to be communicated; thus, the information is communicated by being coded and printed into the optically readable code, which is read and converted into information by a code reader.
