Abstract

PROBLEM TO BE SOLVED: To much more widen application and utilization by using new characters (0-9, A-F) easily identifiable even by the sense of sight, and its identification code system, capable of conducting numerical design by a simple theory to POS, EDI, FA, OA, ISBN or the like used as a present bar code symbol. SOLUTION: 1. The inside of a rectangle is divided into four, and weights of 1, 3, 5, 7 are given to the divided sections. The inside of the rectangle is colored to form a pattern, and the sum of the weights in the colored pattern or the colored part is read out to form 16 characters of 0-9 and A-F (first characters). 2. By combining two characters (the first character), CODE-256 containing an ASCII code revised table is expressed. 3. An easily identifiable pattern among many patterns coloring the inside of the rectangle is substitutively expressed as a second character, application identifier. 4. Two characters (the first character) are joined with a joining sign to make reading easy.

Description

Detailed Description of the Invention

[Object of the Invention] Based on the decimal system, visual identification,
With a code that can express a variety of expressions and variable lengths and has excellent expandability, it will contribute to further labor saving for EDI in the advanced information age.

[0001]

[Industrial field of use] In the modern era, it is said to be the age of mega competition and advanced information technology, and labor saving and shortening of lead time are important themes for companies. In such a situation, anyone can easily and accurately input data in a speedy manner, and the computer automatic recognition technology that realizes the integration of "things" and "information" can be used in any distribution or manufacturing process. It is attracting attention from all directions. Various automatic recognition technologies for computers, represented by barcodes, are technologies that "take in data without human intervention" and are used according to the purpose of use. However, no matter how a computer develops, it is desirable that human beings can visually identify the basics of automatic recognition from the viewpoint of use, and it is automated for efficiency and labor saving. From this recognition, it is possible to visually identify even on the computer as if there are the current letters, numbers and symbols on paper, and "new" that can be easily, quickly, accurately and automatically recognized. By creating a code, we will contribute to further labor saving and lead time reduction in the advanced information age.

[0002]

2. Description of the Related Art 1) The current one-dimensional bar code has no visibility and cannot be visually identified. 2) Since the format of symbols is fixed, the display contents are restricted. 3) Present one-dimensional barcodes are double-displayed with numbers, and are subject to information density restrictions. 4) The character code of each country cannot be expressed. 5) Present one-dimensional barcodes and two-dimensional codes are required to have high printing accuracy. 6) It is difficult to use the same reader when used in combination because the system of 1D barcode and 2D code is different. 7) The two-dimensional code can be minimized but is not visible, and the matrix system tends to have a square shape. 8) Both 1D barcode and 2D code lack design. 9) There are many types of one-dimensional barcodes and two-dimensional codes, and there is a demand for unified ones (having versatility).

[0003]

[Problems to be Solved by the Invention] 1) In modern times, everything is benefiting from the utilization of computers, for which automatic recognition of data is an absolute requirement, and conversely the development of automatic recognition means. Contributes to the spread and advancement of computers, making them more accessible. The most familiar computer automatic recognition method is the bar code printed on every household item. When you want to develop EDI from now on, the identification code system and bar code symbol currently used as a means (including one-dimensional and two-dimensional)
It is considered that the systematic ones will be further developed and standardized. 2) Two-dimensional code PD with one-dimensional barcode stacked
The F417 is evaluated for its minimization and high confidentiality. One-dimensional code CODE-128 is about to become the mainstream of EDI due to the variety of applications. 3) When using the automatic recognition means, a large amount of data may be required like PDF417. On the other hand, ED
When converting to I, a variety of expressions is required like CODE-128, and the display of several lines like ID is easy to recognize, and in addition, it is easy to identify and want to be beautiful. 4) Due to the problems with existing codes, new codes required are based on visual identification, variety of expressions, and variable length of data, and also expandability, accurate reading, inexpensive use, and existing codes. It means compatibility and minimization. Therefore, the new code table should be designed with a new philosophy,
Although the character itself is a two-dimensional code, it is desirable that it can be used as a one-dimensional code. 5) Visual identification means that it is a code, but it can also be said to be a letter, number, or symbol itself. The letters, numbers, and symbols are convenient for computer processing. Therefore, it is possible to freely express using letters, numbers, and symbols on paper, and it is easy for humans to visually identify, so it is easy to recognize visually even when using a computer, and automatic recognition is easy. It is desirable that the new code, such as the case of numbers, symbols, can be directly used as electronic letters, numbers and symbols for computers. 6) The basics of current barcodes are electronically simplified by making the modules that make up the characters binary, and the binary system is the principle. However, the reason that humans can easily understand both theoretically and visually is by the commonly used decimal system, and if a simple and effective decimal expression technique is established, the decimal system will be established. It is possible to create convenient and easy-to-understand code. 7) The existing code is digitized into 0 and 1 by binary conversion, and is electrically expressed by the 8-digit numerical value of the combination. Therefore, if the decimal numbers 0-9 can be easily recognized electrically and optically, the ASCII code can be expressed by a combination of the numbers 0-9. 8) As a result, based on the decimal system, 0-9, AF
A new code (CO
By using DE-256), characters, numbers and symbols can be expressed by two characters as electronic data that can be visually identified, and can be used for many application identifiers at the same time. Also, since four characters can express Kanji, in the Japanese-speaking world, all characters, numbers, and symbols including Kanji can be expressed as electronic data, as in ordinary sentence expressions. 9) Furthermore, a shortened and easy-to-identify expression can be realized by using a connection symbol between a large number of application identifiers and characters. Typical examples are various symbols, and the CODE-256 can create a large number of different symbols by combining a title, an outer frame, and colorization. 10) Regarding visual identification and variety of expressions, pattern recognition is easy as icon display is currently progressing on personal computers, and two-dimensional pattern recognition is easier and easier to recognize. easy. In addition to the case of CODE-256, the weight and the 1/2 display in the frame can be used together to provide the character self-check function. 11) In CODE-256, vertical and horizontal enlargement/reduction of the character itself (and hence the symbol) can be arbitrarily performed, and can be expressed in an arbitrary size according to the required format and character size. Also, by using a large number of application identifiers and concatenation symbols, it is possible to perform detailed classification, so there are many types of expression, a large amount of data, a code that satisfies the variable length of data, easy identification, and designability at the same time. it can. 12) There are five possible ways to display the code, but the code is basically a separable type because it is easy to understand, easy to use, and universal, and it is basically expressed as a pair using a connecting symbol. 1. Principle (1 set of 2 characters) 2. Informal (1 character substitutes) 3. Connection symbol (connects characters with a connection symbol) 4. Direct connection (2 characters directly connected) 5) Tabi-shaped (4 characters directly connected in a Tabi-shaped) 13) Since variable length expressions are possible, it is possible to expand according to the expansion of data. On the other hand, just like increasing the number of digits, you can increase the number of characters above the existing code. The number of digits is simply increased, and existing ones can be used as they are.

[Constitution of the invention] [Means for Solving the Problems]

[0001]

[Character of code character] 1 for existing barcodes
Since the character is composed of several modules, it is difficult to visually identify the difference in the number of modules and characters and the thickness, and there are many arrangement patterns, which cannot be visually identified. The two-dimensional code can be minimized, but it is difficult to visually identify it, and the symbol shape becomes a square, which is easy to win. Therefore, in both cases, visual identification is difficult, and there is a property that information density is restricted due to fixed format. The original purpose of the symbol is to have the necessary information that can be visually recognized and identified, and the necessary information can be put in, and it can be said that automatic recognition is the one that enables minimization and machine reading from the viewpoint of efficiency. As a method of recognition, there is a method of electrically or optically discriminating, and at present, an electrical method is basically used and developed from the application to a computer. When humans visually identify, it is easy to identify by figures, which is expressed by a certain logic,
The simpler the logic, the easier it is to use. Arabic numeral 0
Although 9 is a two-dimensional character, it is used all over the world. If a correspondingly electrically distinguishable figure is devised, the automatic recognition of the numbers will be facilitated, and since the computer is based on the numbers 0 and 1, the automatic recognition of the characters will also be facilitated. The numbers are 1 and 9, 2 and 8, 3
And 7 and 4 and 6 have the property of becoming 10 when added,
This is a function that enhances the utility value of the decimal system. It would be convenient if such a function could be expressed on a figure, and in addition, the expression could be simple like 0 to 9 and erroneous recognition could be prevented. Therefore, paying attention to the above points, we will sort out the character of the figure that becomes the character. 1) Considering that the current bar code is electrically patterned as “Yes, No” and its arrangement, it is expressed as “Yes, No” position (arrangement) on the figure. 2. The condition for a figure to be simple is that it can be distinguished into two: "Yes" and "None".
If the position (without) has a simple logic, the discrimination becomes easy. 3) Ten figures are required to represent the numbers 0-9. Considering the property of being the complement of 1 and 9, 2, 8 and 3, 3 and 7, 4 and 6, it can be said that it is the same as the figure and is desirable if the relationship on the figure is complementary. 4) It is of little use value today when computer recognition is required only by patterning on figures. For this reason, it is necessary to make not only a pattern but also a numerical difference. (If possible, add one by one like numbers.) 5) In order to prevent erroneous recognition, it is necessary to avoid erroneous recognition as another figure due to the presence of voids, spots, etc. Any pattern other than the pattern with the “Yes, No” classification is not recognized, cannot be easily added and removed, and has a self-check function in which the numerical value changes if the pattern is altered. 6) The data is mainly represented by numbers or letters. The application identifier is a simplification of the ID, and the data contents cannot be expressed even if the items are classified. For this reason, it is desirable that the character that represents the data is simple and easy to understand, and that does not cause misreading. It is best to use decimal numbers for that.
CODE-256's 0 to 0 can be used to visually identify the system of decimals, and in addition, to be able to clearly and electrically identify it electrically and optically.
It is the numeral representation of 9, and the letters are the same as the numerals in which the numerals are connected by a connecting symbol. Therefore, CODE-2 is easy to see and can express numbers and letters in decimal.
56 is the optimum EDI code.

[0002]

[CODE-256 design concept] The design concept is as follows in pursuit of problems with existing code and new functions. 1) It can be easily visually identified by humans. (Pattern recognition, 1/2 coloring, weight, pair in decimal system) 2) Basic representation in decimal system. 3) All ASCII codes can be expressed. 4) Can express multiple languages including Kanji. 5) Only necessary data can be expressed in variable length. 6) The size of the character (hence the symbol) is free. (Vertical and horizontal are unique, golden ratio (1:
It is possible to flexibly comply with the required standard, which is close to 1.8). 7) It is highly expandable by increasing various application identifiers and their detailed classification numbers. 8) It is possible to use the characteristics of both the one-dimensional code (ID) and the two-dimensional code (data) as they are. (EDI conversion, compatible with current codes, there is no limit on the amount of symbols) 9) Colorization is easily possible. 10) Facilitates compatibility with symbols in existing code. 11) It can be used inexpensively. (Since the standards of the printing system are loose, you can use it by FAX regardless of the paper quality.) 12) Since the amount of information can be increased, the character can be minimized. (The aspect ratio is free even in the case of multiple stages, and the end can be shaped by the end code.) 13) It is possible to express from either the left or right. 14) I want to read it securely even if it gets dirty. 15) I want to read at high speed regardless of the reading direction. 16) I want to have high security.

[0003]

[Means for Solving the Problems] 1) The above

As stated in [Character of Code Character], in order for the figure that becomes the character to be simple, it can be distinguished into two, "Yes, No", and the arrangement of "Yes, No" on the figure is a simple logic. Need 10 figures to represent the numbers 0-9, and 1 and 9,
2 and 8, 3 and 7, 4 and 6 have a complementary relationship on the figure, not only pattern recognition but also numerical difference, and to prevent misrecognition, voids and spots Therefore, it is required that the figure should not be erroneously recognized as another figure and that it has a self-check function. Therefore,

[Figure 1]

FIG. 2 considers a figure in which the inside of a rectangle is divided into four equal parts and weights (0, 1, 3, 6) and (1, 3, 5, 7) are added to each. Then, a part of the entire internal area is color-painted, and the total weight of the color-painting pattern and the color-painted portion is read. As a simple example of the pattern, the areas in the rectangle are simply contrasted in black and white by ½, which facilitates visual recognition and identification and, at the same time, since black and white have the same area, it serves as a check function for voids and spots. 2)

In FIG. 1, weights can range from 0 to 9, 0,
The numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 can be expressed as they are. However, considering various uses, it is desirable to be able to represent ASCII codes in the English-speaking world, and to represent hiragana, katakana, and kanji in the Japanese-speaking world. 3)

In Fig. 2, since weights from 0 to 16 are possible,
Consider a method of expressing patterns of insufficient weights (1 to 3, 13 to 16) (regardless of 1/2 expression). 4)

FIG. 3 considers a method of expressing a pattern having weights of 1 to 3 and 13 to 16 as shown in FIG. 5)

As shown in FIG. 3, the numbers 0 to 16 can be expressed by one figure, and weights can be attached to each figure.
In addition, since 256 characters can be expressed by a combination of two figures having weights of 1 to 16, 256 kinds of codes including all ASCII codes (128 kinds) can be expressed, and computer correspondence is also possible. Therefore 1
The figure representing the numerical value of ~16 is the character of CODE-256 (half & half code). 6) 16 numbers from 0 to 9 and A to F, a figure representing a character is represented as the first character, a double number of columns and rows in the ASCII code revision table, and a symbol are represented as one figure. Is the second character. In the CODE-256 table, those other than the ASCII code revision table are represented by one figure as an application identifier. 7) The shape of the figure is basically a square, but in order to make it easier to recognize the beauty of expression and the directionality when expressing in multiple stages, a rectangle with a golden ratio (1:1.8) is the standard. .. 8) It is the same as a one-dimensional barcode when it is used in one stage, and it is the same expression as a two-dimensional code when it is used in multiple stages. 9) The pattern that colors half of the area inside the rectangle is

[Fig. 2]

FIG. 4 is variously conceivable, which is used as a second character or an application identifier. 10) Application identifiers are common to each language, in order to express more data in a shortened form, and to avoid using characters other than 0-9 that can be modified, the column and row It is assumed that two characters are represented by one figure which is easy for pattern recognition. 11) Numbers, letters, and symbols can be represented by a pair of characters in two columns and rows. In order to easily identify a pair of characters in these two strings, it is only necessary to connect two strings of characters, and various codes may be used depending on the difference in the connection symbols. It is assumed that the connecting symbol for coloring the lower half between the characters is A-type to represent each language, and the language name is identified by the application identifier except English which is a general-purpose word. Similarly, in Japanese, the Hiragana code is represented by the concatenation symbol B type that colors the upper half of the characters, and the Katakana symbol code is represented by the concatenation symbol C type that colors the upper 1/4 and the lower 1/4 of the characters. It shall be. Also, the kanji is J
Since it can be expressed by 4 consecutive numbers of IS code and dot, A
Type 4 quads for type 1 Kanji, Type B quads for type 2
It is possible to express 30,000 kanji by expressing the 3rd kind kanji with 4 kinds of kanji and C type. It should be noted that more kanji can be expressed by changing the combination of connecting symbols. Also, foreign kanji such as China may be identified by an application identifier. 12) In order to express the detailed classification of the application identifier, use an H-shaped concatenation symbol that colors the center half of the character immediately after the application identifier, and use a 2-digit or 3-digit classification number. Connecting. 13) Use second characters and application identifiers to shorten data and messages, and to make common ones easier to identify. One-character reading represents numbers and various symbols and application identifiers, and two-character reading represents various characters.
Kanji reading represents the Kanji symbol.

(Function) 1) A character based on 16 figures which is easy to understand, which can be visually identified, and which can be identified electrically and optically is devised, and a combination of these two 16 characters CODE that represents 256 codes with
-256 is proposed, and various languages can be supported by converting the language code. 2) Part of CODE-256 is the ASCII code revision table. Since there are many parts of the language code other than characters that are common throughout the world, and in order to save labor and simplify identification, they are represented by a single figure (character), which is referred to as the second character or application identifier. 3) By using four types of connecting symbols that connect two characters, it becomes easy to identify characters and various codes (English and others, hiragana, katakana) can be easily identified. Further, the classification function can be increased by adding a detailed classification number based on the H-shaped concatenation symbol immediately after the application identifier. 4) The data can be expressed in variable length, and the size of the character is free, so composite type expression that combines the use as an ID and the use as data is possible. 5) Many different symbols can be expressed by combining titles, outer frames, and colorization in data and messages. 7) In CODE-256 (half & half code), the character is closely related to the weight, and it is easy to understand as an image. For this reason, the ASCII code table has already been standardized, but when using CODE-256, the order is rearranged so that two ASCII characters 0-9 can represent the ASCII code symbols and alphabetic characters.

The ASCII code revision table as shown in [Table-1] shall be used. Codes for each language are also organized according to the ASCII code. 8) Characters can be expressed from 0 to 16, but 0
Since it is easy to modify the pattern, only characters with weights 1 to 16 are used. 9) The weights other than 3 to 12 (1 to 2, 13 to 15) can be modified. In addition, it is easy to misidentify when it is made extremely small, so I would like to avoid using it as much as possible for EDI and barcode. Therefore, the second character and one character of the application identifier are used as substitutes. 10) Each character itself has a self-check function, so a check digit is not usually required. But,
When using a concatenation symbol in EDI or the like, a void may occur between characters and it may be mistaken for a concatenation symbol (although it is defined as 1/2 high). Therefore, if a check digit is required, the application identifier for the check digit is used. 11) The patterns and weights in the rectangle are recognized, but the thickness of the outer frame and the thickness of the connection symbol (interval between characters) are not less than a certain thickness so that they can be read even if they are minimized. Secure.

[How to use the character set]

[Standards for characters, etc.] (Graphic scale 80%) When the width of the character is set to 10 mm... Basic form 1) The horizontal/vertical ratio of the character is the golden ratio (1:1.8). 2) Title standard (Type A) Square is the vertical length of the character (18 mm)
Is one side. The width of a (B type) rectangle is the same as that of a square title (1
8 mm) and the vertical length is the same as the second stage of the character (39 mm). (C type) The horizontally long type is used for two-tiered characters. 3) The space between characters is twice the thickness of the frame (2mm)
In the case of multiple stages, the space between the upper and lower characters is 3 times (3 mm) the thickness of the frame. 4) Arrangement of peripheral spaces when an outer frame is attached The upper and lower spaces should be 5 times (5 mm) the thickness of the frame. The left and right spaces are 10 times (10 mm) the thickness of the frame.
The space between the title and the character is 4 (4 m
m) times.

[Character usage] 1) Start character
Display at the beginning of the symbol Note) The application identifier is also the start character. 2) Stop character is displayed at the end of the symbol. 3) Corner character Displayed at the beginning of the bottom row in the case of multi-stage 4) Terminal character Use as stop character when application identifier is used as start character Note) Prepare multiple items to prevent misidentification when flipped

[Separate character] Used to separate IDs and data Note) Some have a meaning in combination with the application identifier.

[Expression using concatenation symbol]

[Each language, English, hiragana, katakana] Numbers, symbols (second character) and application identifiers are expressed by one character. Characters are represented by two consecutive characters in columns and rows, and Kanji is represented by four consecutive characters in JIS Kanji code, so the connection is emphasized, and in order to make identification easier, connect character kaku with connecting symbols. good. The shape of the concatenation symbol determines the usage for the language.

[Kanji] Kanji can be expressed by 4 characters in columns and rows of JIS kanji code. The language code is displayed for kanji other than Japanese. Note) The number of types can be increased by combining different symbols. It is also possible to display in 5 rows. Except for characters, it is common throughout the world and is simplified and expressed as one character. All languages can be mixed and expressed by adding the application identifier of the language code.

[Application identifier subdivision] In order to enable subdivision of the application identifier, two or three subsections are arranged immediately after the application identifier. It is not necessary for a general-purpose application identifier. Use prominent ones for specific and general purposes. The classification is divided by a separator and can be subdivided in any number of stages.

[How to use application identifier and separator] 1)
Basic application identifier + data separator + data The data order is fixed and the data is variable length. 2) Specific/general-purpose application identifier + data Fixed format, effective for specific and general purpose. 3) Application identifiers that classify application identifiers + detailed classification codes + data Application identifier + multiple detailed classification codes + data The data order is fixed, but the data is variable length. There are two ways to express the data part: 1) and 2). The standard for classification is 2 or 3 digits.

[Cord set character] Usually, it is placed immediately after the start character. Since English and Japanese can be identified by a concatenation symbol, the language code application identifier does not necessarily have to be set.

[Expression method by CODE-256]

A country has two stations, a prefecture has three stations, and a municipality has four stations. The chief of the institution uses the black and white inverted application identifier, and the separator also uses the black and white inverted version. The one immediately before the terminal character is the name of the institution or the chief of the institution. Quasi-public agencies use vertically inverted application identifiers and separators as well.

It is necessary to format the organizational system of prefectures and municipalities.

[Effects of the Invention] 1) Characters are simple in design, so high printing accuracy is not required. A total of 10 characters form a pair as a pattern, which is easy to understand and can be visually identified. 2) The aspect ratio of the character itself is the golden ratio (1:1.
It is close to 8), and in principle, the contrast of black and white is 1/2, which is excellent in aesthetic sense. 3) Since the character itself can be scaled up and down in any direction vertically and horizontally, it is possible to make a composite type representation in which the ID is large and the data is small. 4) There are many ways to create a character that contrasts with 1/2 black and white, or a character that is easy to distinguish, and can be used as an application identifier. 5) The functions can be expanded by introducing colorization such as coloring the black background and coloring the white background, and also improve the aesthetic sense. 6) Since there are a maximum of 256 numbers, characters, and symbols that can be represented by two characters (first character), all ASCII codes (128 types) can be represented, and all 1-byte code tables can be represented. 7) In addition to the ASCII code expression, various application identifiers can be used to include multiple items of messages and at the same time shortened expression is possible. 8) By using the concatenation symbol, it is easy to read, and at the same time, the application identifier can be omitted or abbreviated. 9) Numbers, languages, and various symbols can be freely expressed within one symbol. Also, code conversion is easy, and multilingual can be expressed in one message by using an identifier (national language) or an abbreviated identifier (only main word). 10) By using the application identifier, only necessary items can be easily expressed and sorted. 11) In principle, two-character reading is used, and one-character reading is a number/symbol or various application identifiers. Kanji can be expressed by four-character reading by setting the JIS code and dot reading. It can represent numbers, letters, symbols, and various application identifiers. It is also possible to express as many kanji as necessary by changing the combination of concatenated symbols for reading four characters. 12) There is an advantage in ideographic characters that can be expressed with a small number of characters, and Japanese that expresses a mixture of Kanji, Hiragana, Katakana, and English characters is superior. However, for standardization that is applicable to the world, it is desirable that characters be created as separate and independent codes and that concatenation symbols be used because they are easy to identify and have commonality. 13) The basic structure of the character is 1/2 the area within the rectangle.
Since the pattern recognition is performed only by contrasting it with black and white one by one, and the visual identification is easy, it is not necessary to attach a numerical expression, and the density of information amount can be increased. In addition, since the black and white have the same area, it has a self-check function that makes it unreadable if there are voids or spots, and thus the misreading rate is low. Also, pattern recognition, weight reading, and cross-checking by 1/2 reading are possible. 14) Characters are the display of the space inside the rectangular frame, and the thickness of the outer frame and the space between characters can be changed, and the aspect ratio can be changed. Can be enlarged or reduced to improve legibility as a logistics sign. 15) The length of the symbol is equal to or less than that of various existing symbols, but the area is reduced, so that the expression items and the expression amount of the data are increased. 16) The division between data can be clearly discriminated by incorporating an application identifier, a detailed classification number, and a separator. This makes it possible to express the variable length by arbitrarily increasing or decreasing the number of characters and freely increasing or decreasing the amount of information. However, when the format is fixed, by inserting a separator between data, it becomes easier to identify the partition. 17) When the amount of information is large and the symbol is long, it is possible to display the arbitrary amount by stacking in a stack method. In this case, the length of one step can be arbitrarily set within the range of the reading width of the reader. In the case of multiple columns, the number of vertical and horizontal characters can be adjusted to any number of characters by adding non-space characters. Also, by inserting a corner character, it is possible to recognize the directionality in the case of the multistage type. 18) Both the one-dimensional code representation (one-stage display) and the minimized two-dimensional code representation (multi-stage display) are possible with the same character, which simplifies the performance of the reader. 19) It can be expanded by increasing the detailed classification number of the application identifier, and is highly expandable. 20) Various symbols of existing one-dimensional code and two-dimensional code can be expressed, and the existing code can be easily interchanged. 21) Pave the way for applications from binary to decimal and hexadecimal. 22) The application from electricity (weight recognition) to light (pattern recognition) can be easily converted. 23) Both single code and continuous code can be expressed. 24) When creating a ciphertext, each user can create a unique format, and by making the character itself square-shaped, it can be made difficult to decipher, such as rotating and reversing colorization.

Claims (8)

[Claims] 1. A rectangular shape is divided into four parts in a square shape, and weights of 1, 3, 5, and 7 are attached to the areas of the respective divisions. Then, a part of this rectangle is colored to form a pattern, and the total of the weights of the coloring pattern and the colored part is read to obtain a code character. 2. The weight of the whole rectangle is 16, so that 1 to 1 is basically used as a pattern for coloring a half area of the rectangle.
The weight (pattern) of 6 represents the numbers 0 to 9 (first character) and the letters A to F (first character). [Figure 3] 3. A number from 0 to 9 (first character) and A to
A code table (CODE-256) expressing numbers, letters, and symbols is created by combining two of the 16 characters of the letter F (first character). Of these, 00-C9
The part of is corresponded to the ASCII code table in which the order is changed (called an ASCII code revision table). [Table 1] 4. A number, a character, and a symbol expressed by a combination of columns (rows) of the code table (two characters each) in a row (first character) and letters A to F (first character) are 0. The number 9 (first character) and the connecting symbols connecting the letters A to F (first character) are used to emphasize the combination and facilitate identification. [Table 1] [Table 2] [Table 3] 5. A number of patterns are conceivable in which half of the rectangle is colored and the weights are read, but these are substituted for numbers, letters and symbols expressed in two columns and rows in the code table, and ASCII codes are used. The one located in the revision table is used as the second character, and the others are used as the application identifier. [Table 1] [Table 2] [Table 3] 6. The application identifier and the classification function of the application identifier are expanded by using a combination of a fine classification number represented by a concatenation symbol. 7. A large number of symbols are created by combining a title, an outer frame, and curling with respect to data or a message. 8. A rectangular shape is divided into four parts in a square shape, and weights of 0, 1, 3, and 6 are attached to the areas of the respective divisions. Then, a part of this rectangle is colored and patterned, and the total weight of the colored parts is read to obtain the character of the code. [Figure 1]
