Crossed bar code

Abstract

To provide methods different from conventional methods of displaying and reading bar codes, and to contribute to an expansion in the range of use by increasing the amount of information that can be assigned the bar codes and increasing the total number of bar codes.SOLUTION: While a conventional bar code is displayed as an array of vertical lines (perpendicular lines), a bar code disclosed herein has transverse lines (horizontal lines) superimposed on the vertical lines. The bar code thus has a row of vertical lines and a row of horizontal lines. The bar code is not only displayed in monochrome (two colors), but displayed in full color (multiple colors) to solve the problem.SELECTED DRAWING: None

Summary of the Invention

Problems to be Solved by the Invention

[0003] Barcode, which is one of the identification codes, is used in many applications. However, due to the limitations of its display method (display conditions), the amount of information that can be assigned to one code has been limited. When used under the same conditions (constraints), not only an increase in the amount of information to be assigned and the use of printed barcodes, etc., but also an increase in the total number of barcodes is required to support their use in optical signal applications (display on a display) in information processing within a computer.

Means for Solving the Problems

[0004] (1) Conventional barcodes were arranged and displayed as vertical lines. However, if a horizontal line arrangement is superimposed here, it becomes a barcode with a display where the vertical and horizontal lines intersect. By doing so, two barcodes are combined into one barcode, and more information can be assigned. (The method of reading this barcode with an intersecting line shape is not a conventional infrared sensor barcode reader, but a barcode reader that irradiates cross-shaped infrared rays so that the vertical line arrangement and the horizontal line arrangement can be read simultaneously). In addition, the display method of intersecting the line arrangements includes not only vertical and horizontal lines but also a method of intersecting diagonal lines drawn from opposite positions (X-shaped display), which has the same effect. By using the method described in (2)(1) and making the cross-line shape a full-color (multi-color) display instead of a monochrome (two-color) display, more information can be provided. A method of converting a full-color (multi-color) display barcode into a binary (0 and 1) digital signal is to assign an order to the colors used and set it to be binary (0 and 1) in a combination of a specific color and other colors. Set it to be read in order. (For the method of reading this multi-color display cross-line shaped barcode, use a code reader that utilizes technologies such as a camera with an image sensor capable of color identification.) Solve the problem using the methods described in (1) and (2).

Claims

1. The barcode, which is one of the identification codes, arranges monochrome (two-color) bars (vertical lines) and the information attached is read by a dedicated device (infrared sensor code reader) and converted into a digital signal by the program of the device. (Apply the two-color display to the binary system of 0 and 1 for digital conversion). By using this barcode not only in the conventional vertical line arrangement but also adding a horizontal line arrangement, and making a display where the vertical line column and the horizontal line column are overlapped (the vertical line column and the horizontal line column are crossed), even with the same method of attaching and reading information of the identification code of the same barcode, more information can be attached. By making the barcode a display where the vertical line arrangement and the horizontal line arrangement are overlapped (crossed), it becomes a form of combining two barcodes into one, a method of attaching more information and further increasing the total quantity of the barcode itself. (The ratios such as the lengths and numbers (array spaces) of the vertical and horizontal lines are not limited). (Since the conventional barcode reader (infrared sensor code reader) cannot read the vertical and horizontal crossed barcode, the infrared irradiation should be a reader that can simultaneously irradiate in a cross shape for the vertical line column and the horizontal line column, or a device such as a camera using an image sensor should be used). (When the barcode is displayed in a crossed manner, not only the intersection of the vertical line (vertical line) and the horizontal line (horizontal line), but also the intersection of the diagonal lines has the same effect. A method of overlapping (crossing) a diagonal line column from the upper right to the lower left direction and a diagonal line column from the upper left to the lower right direction for display.

2. With the method described in Claim 1, instead of a barcode that overlaps (crosses) a monochrome (two-color) vertical line column and a horizontal line column, a barcode that overlaps (crosses) a full-color (multi-color) vertical line column and a horizontal line column can provide more information even for barcodes of the same shape and size. (Similar to the method described in Claim 1, not only the intersection of the vertical line (vertical line) and the horizontal line (horizontal line), but also the intersection of the diagonal lines in the reverse direction is acceptable). The method of converting a full-color (multi-color) barcode into a digital signal in the binary system (0 and 1) is to set it to be in the binary system (0 and 1) with a specific color and other colors for the colors used. Set this for all the colors used and number them in order. And set it to read in order. By doing so, the barcodes are grouped according to the number of colors used in one barcode, and more information can be added. In this way, by changing a monochrome (two-color) barcode to a full-color (multi-color) barcode, more information can be added to one barcode, and furthermore, the total quantity of the barcodes themselves can be increased. (Since a full-color (multi-color) barcode cannot be read by a monochrome (two-color) barcode reader (infrared sensor barcode reader), a device such as a camera that can identify colors using an image sensor is used.)

3. A barcode using the method according to Claim 1 and Claim 2, and a reading device therefor.

4. An OS (program software) using the reading device according to Claim 3.

5. A service or business using the barcode and reading device according to Claim 3, and the OS (program software) according to Claim 4.
