<p>PURPOSE:To secure the printing with high density when the binary information is converted into print codes to produced bar codes, by coding binary information ''0'' and ''1'' with white/black picture elements and black/white picture elements respectively with addition of a synchronizing signal and a frame area. CONSTITUTION:A frame area A consists of all black recording picture elements of N2 units (N2=4 as shown in the figure) with a fixed width. While an area B indicates the columns of the short side direction (X) of an odd order or that of an even order. In the case of an odd order, the picture elements start at a white one to form N1 units of recording picture elements equal to the number of windows of close gathering where white and black elements are set adjacent to each other as shown in a figure (a). While in the case of an even order, the picture elements start at a black one as shown in a figure (b) to form N1 units of recording picture elements where white and black elements are adjacent to each other. In an area C the binary information on sound signals, product codes, etc. are printed and ''0'' and ''1'' are coded in the order of white/black picture elements and black/white picture elements respectively.</p> |
