Abstract

PURPOSE:To obtain a code system which requires any speciality for printing technique by coloring optional parts among four divided parts obtained by dividing a circular figure by three concentric circles. CONSTITUTION:The three concentric circles which decrease in diameter in order are placed on the circular figure 2 to divide the circular figure into four, and one-four optional parts among the divided parts 6-9 are colored to provide a code where light reflectable parts and unreflectable parts are formed. Further, this system is provided with a sensor which projects light on a part extending outward from the center of the code and detects projected light reflected by the reflectable parts of the code and a decision circuit which reads the meaning of the code from the output signal of the sensor. Consequently, the code is formed by handwriting at need without requiring any high-level printing technique and the usage becomes extremely wide.

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 a thin line and a thick line to form a reflective area and an unbalanced reflective area, and identifies the reflective area and non-reflective area of the article.

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 was not perfect, and there were still issues to be solved. 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 idea will be introduced instead of a bar code.The present invention was made in view of this point.

(Means for Solving the Problems) As a means for solving the above-mentioned problems, the present invention divides a circular shape into four by superimposing three concentric circles whose diameters are successively smaller on a circular shape, and divides the circular shape into four parts. By coloring arbitrary parts from one to four of the divided parts of the divided figure, a code is created that forms a part that can reflect light and a part that cannot reflect light. A sensor that irradiates light onto a portion facing the code and detects that the irradiated light is reflected by a reflective portion of the code, and a discrimination circuit that reads the code meant by the code from the output signal of the sensor. This is a code system with a configuration that includes:

(Function) With such a configuration, the code is formed in a circular shape and does not require any detailed parts, so it can be easily implemented without requiring any special printing technology. It is also possible to color the divided circular parts by hand.

It is now possible to create a personal code, which was not possible with barcodes, and since the code is read over the entire circle, it is possible to read the code with high precision.

(Embodiment) Next, one embodiment of the present invention will be explained with reference to the drawings.
In the figure, l is a code, and a circular figure 2 is divided into four parts (area parts) 6, 7, 8 by three concentric circles 3, 4.5.
．． It is divided into 9 parts. Color 1 to 4 of these divided parts arbitrarily (black can be used), and depending on the position and number of the colored parts, from rAJ to ``0'' to ``9'' as shown in Figure 2. A total of 16 types of codes up to rFJ can be obtained. This code 1 is normally colored by printing, but it may also be done by hand. The codes 1 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 radiated outward from the center of the four parts 6, 7, 8. Reading will be performed. Therefore, the reading device includes a light emitter that irradiates the entire area with light and a sensor that distinguishes between reflected light and non-reflected light.
A discriminating circuit is required to read the code meaning 1 from the output signal of this sensor.

(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 is this possible, but you can also create codes by hand if necessary, which has the advantage of greatly expanding the range of uses.
