Embodiment Construction

[0015] The present invention discloses an embodiment altogether, set forth as follows:

[0016] The "bar code of empty bar" of Arabic numeral 1 is represented by "bar of 1 unit width + bar of 1 unit width + bar of 1 unit width" (which can be expressed as "101"), and "empty bar and empty code" can be used But it is not limited to use "1 unit wide space + 1 unit wide bar + 1 unit wide space" (can be expressed as "010") to represent it;

[0017] The "bar code of empty bar" of Arabic numeral 2 is represented by "1 unit wide bar + 1 unit wide space + 2 unit wide bar" (which can be expressed as "1011"), and "empty bar and empty code" can be used But it is not limited to use "1 unit wide space + 1 unit wide bar + 2 unit wide space" (can be expressed as "0100") to represent;

[0018] The "bar code of empty bar" of Arabic numeral 3 is represented by "1 unit wide bar + 2 unit wide space + 1 unit wide bar" (which can be expressed as "1001"), and "empty bar and empty code" can be used B...

Abstract

The invention belongs to an Arabic numeral barcode with greater black-and-white contrast between two adjacent numbers, and relates to the technical field of digital barcodes. The black-and-white contrast between two adjacent numbers is not enough, and the read-only accuracy of the code reading device is not enough. The object of the present invention is to provide a kind of Arabic number bar code that the black-and-white contrast contrast of two adjacent numbers is bigger, in order to realize above-mentioned purpose, the bar code of " empty bar code " of Arabic numeral 0 in the present invention uses the bar of " 3 unit width + 1 unit wide space + 1 unit wide bar" (can be expressed as "11101") to represent the three, "empty bar and empty code" can be used but not limited to "1 unit wide space + 2 unit wide bar... ... The present invention has the advantage that the contrast between black and white of two adjacent numbers is completely sufficient.

Description

technical field [0001] The present invention relates to digital coding technology, specifically, one-dimensional code in bar code. Background technique [0002] The black-and-white contrast between two adjacent numbers is not enough, and the read-only accuracy of the code reading device is not enough. Contents of the invention [0003] The object of the present invention is to provide a kind of Arabic numeral bar code that the black and white contrast contrast of two adjacent numbers is bigger, in order to realize the above object, the present invention adopts following technical scheme: [0004] 1, the present invention is a kind of Arabic number bar code that the black and white contrast contrast of two adjacent numbers is bigger, it is characterized in that, [0005] The "bar code of empty bar" of Arabic numeral 0 is represented by "3-unit wide bar + 1-unit wide space + 1-unit wide bar" (which can be expressed as "11101"), and "empty bar and empty code" can be used Bu...
