Abstract

PURPOSE:To increase information with a color and to decrease the display area by performing a process color printing for a figure symbol and a character symbol at every bar. CONSTITUTION:For a bar code label 1, for example, a two-color-printing figure symbol 2 and a two-color-printing character symbol 3 are printed with a black and a yellow at every bar. When a bar code reader 4 for color identification scans the bar code label 1, it reads the two-color-printing figure symbol 2 and the two-color-printing character symbol 3, and identifies the black and the yellow, a bar code decoder 5 decodes transferring information, and displays it one a display section 6. Thus, the quantity of the transferring information can be increased, and the display area can be decreased.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to barcodes.

[Conventional technology]

Conventionally, barcodes were printed in a single color with numeric symbols and nine character symbols.

[Problem that the invention seeks to solve]

In the above-mentioned conventional barcode, one numeric symbol and one letter symbol are printed in a single color, so if you want to increase the amount of information to be transmitted, it is necessary to increase the number of one numeric symbol and one letter symbol. This has the disadvantage that the display area increases.

In contrast to the above-mentioned conventional barcode, the present invention uses the numeric symbol 1
It has the original content of increasing color information to a single numerical symbol and character symbol by printing character symbols in multiple colors for each bar, and reducing the display area of the single numerical symbol and character symbol.

[Means for solving problems]

The barcode of the present invention is characterized in that it is displayed using a plurality of colors.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a schematic diagram of a first embodiment of the present invention. In FIG. 0, 1 is a bar code decoder, 2 is a numeric symbol for two-color printing, and 3 is a letter symbol for two-color printing.

FIG. 2 is a schematic diagram of a barcode reader for color identification. In FIG. 6, 4 is a barcode reader for color identification, and 5
is a barcode decoder, and 6 is a display screen.

The barcode label 1 has two-color printed numeric symbols 2 and two-color printed character symbols 3 printed in black or yellow for each bar. When the barcode label 1 is scanned by the color identification barcode reader 4, the color identification barcode reader 4 can read the numeric symbol 2 of the two-color printing and the character symbol 3 of the two-color printing, and read the numeric symbol 2 of the two-color printing and the character symbol 3 of the two-color printing. Distinguish between black and yellow in character symbol 3. Interpretation of 2-color printed numeric symbol 2 and 2-color printed character symbol 3, and discrimination between black and yellow in 2-color printed numeric symbol 2 and 2-color printed character symbol 3. , the barcode decoder 5 decodes the transmitted information and displays the transmitted information on the display screen 6.

FIG. 3 is a schematic diagram of a second embodiment of the invention.

In the figure, 7 is a barcode label, 8 is a number symbol for two-color printing, 9 is a character symbol for two-color printing, 10 is a number for two-color printing, and 11 is a character for two-color printing.

In this embodiment, the barcode label 1 shown in FIG.
By adding the number 10 printed in color and the letters 11 printed in two colors, identification by the human eye can be made possible.

〔Effect of the invention〕

As explained above, the present invention can increase the amount of information to be transmitted by identifying the printing color of, for example, the numeric symbol 2 printed in two colors and the character symbol 3 printed in two colors, and the amount of information transmitted can be increased. This has the effect of reducing the display area of the character symbol 3 in two-color printing.

In addition to the two-color barcode used in the above description, the present invention can further increase the amount of information by using a barcode in other colors using three or more colors.
