Abstract

PURPOSE:To realize a code system without requiring any high-level printing technique by dividing a circular, rectangular, or triangular figure into plural parts and coloring the divided parts in color distinctively from adjacent parts. CONSTITUTION:The circular, rectangular, or triangular figure is divided into plural parts, which are colored distinctively from adjacent parts to provide a code formed using a difference in color; and a sensor which detects the difference in color of the code and a decision circuit which reads the meaning of said code from the output signal of the sensor are provided. Consequently, the code is formed of the color provided to the divided part and any fine part is no required at all, so there is no speciality required in the printing technique and the code is easily formed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a code system used to display identification, classification, price, etc. of articles.

(Prior Art) As a code system for displaying the identification, classification, price, etc. of articles, there is a bar code system.

This combines thin lines and thick lines to form parts that can reflect light and parts that cannot reflect light, and these reflective parts and non-reflectable parts can be used to identify articles.

A code is formed to indicate classification or price, and light (light emitted by a light-emitting semiconductor) is irradiated onto this code and reflected to read the code meant by the code.

(Problems to be Solved by the Invention) Since this bar code can reliably and easily read the above-mentioned identification, classification, price, etc., it has become widely popular and is now used in all fields. However, this barcode system cannot be said to be perfect.

Issues remained to be resolved. In other words, when printing barcodes on the product itself or on the packaging of the product, misalignment or smearing may occur in areas with small gaps between thin lines, and in order to prevent this, very strict measures must be taken. This means that it is necessary to carry out technical management. Therefore, it is expected that a code system based on a completely new concept will be introduced in place of the bar code.9 The present invention was made in view of this point.

(Means for Solving the Problems) As a means for solving the above problems, the present invention divides a circular, square, or triangular figure into a plurality of parts, and divides the divided parts into adjacent parts. is provided with a code that is distinguished by a distinguishable color, and is provided with a sensor that detects the difference in the color of the code, and a discrimination device that reads the code meant by the code from the output signal of the sensor. This is a code system configured with a circuit.

(Function) With this configuration, the code is formed by the colors applied to the divided parts, and there is no need for detailed parts at all, so no special printing technology is required. It can be easily implemented. In addition, the divided parts can be colored by hand, making it possible to create personal codes that were not possible with barcodes.
Furthermore, since the code is read over the entire figure, it is possible to read the code with high accuracy.

Note that colors include not only colors that can be visually confirmed due to paints and colorants, but also optical colors that can be identified using special optical filters and electric circuits.゛(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 is a code, and a circular figure 2 is connected to three concentric circles 3, 4, .
5 divided into four parts (area parts) 6° 7.8.9. One to four of these divided parts are colored in any color that allows them to be distinguished from the adjacent parts, and depending on the color they are numbered ``0'' to ``9'' and rAJ to rFJ.
You can obtain all 16 types of codes 1 up to. This code 1 is usually colored by printing, but it may also be colored by hand. This code l is
The descriptions are arranged in an appropriate order depending on the classification or price of the item to be displayed.

When reading this code l, light is simultaneously irradiated outward from the center of the four parts 6, 7, 8, and 9 of the circular figure 2, and the color form of the reflection of this part is determined. will be read. Therefore, the reading device requires a light emitter that irradiates the entire area with light, a color sensor that identifies the color of the reflected light, and a discrimination circuit that reads the code meant by code l from the output signal of this sensor. shall be.

In the embodiments described above, a circle is divided concentrically to form a code, and the divided parts are colored. However, the present invention is not limited to a circle, but can be formed into a rectangular shape, for example, into four shapes. The triangle may be divided into four parts and each part may be colored to distinguish it from the adjacent part, or a triangle may be divided into four parts and a similar configuration may be made. Furthermore, one color includes not only colors colored with paint or colorants, but also optical colors that can be identified using special optical filters or electric circuits.

(Effects of the Invention) Since the present invention is a code system configured as described above, it is possible to solve the problems of conventionally commonly used barcodes, that is, the need for advanced printing technology. Not only can you do this, but you can also create codes by hand if necessary, which has the advantage of greatly expanding the range of uses.
