Detailed Description of the Invention

[0001]

[Industrial field of application] The disclosed technology is used in POS systems and F
This belongs to the field of the technology of the two-dimensional code used for product processing management or the like that is functionally used in the A system.

[0002]

As is well known, the prosperity of civil society depends largely on the advanced development of industrial society, and both civil society and industrial society are supported by the rapid development of science and technology in recent years. the article is adapted to migrate to the society that has been supported by Daiwa Ri information to energy, information processing system, which was developed in the high-definition centered on the computer production companies, as well distribution, deeply penetrate up to the civic life However, further development is required, and the research, development and practical application thereof are being promoted more and more.

[0003] In addition to the production and distribution of goods, the wave of informationization has come to the point of transportation, and information has spread to every corner of society as a network.

In the distribution system directly connected to the personal life of an individual, the so-called POS system has become common sense in recent years in terms of stable supply and demand for consumer life, safe consumption, reliable and prompt supply, and the like. In the markets such as shops, department stores, etc., information codes such as bar codes, which are the center of information processing, have been used everywhere, greatly contributing to healthy society.

Thus, in a code system such as the so-called bar code, accurate and speedy information processing beyond human senses has come to appear over a wide range. Not only mere distribution management and inventory management, but recently there is a momentum that it will be introduced as a so-called FA system for production management and the like.

Therefore, various researches and developments have been made on an automatic recognition processing system corresponding to a man-machine interface in which binarized data is optically detected through a scanner and a predetermined processing is performed by a computer. With the practical use of today's bar code system, various necks and other problems have been raised.

That is, since the bar code is a one-dimensional bar mark data processing, there is a limit to the amount of information even if a multi-step bar code is developed as a two-dimensional bar code, and an extremely high printing technique is required. As a result, inconvenience of high cost occurs, the space on the display surface of the object to be processed is individually limited, and surface sensing is impossible. Etc. has become a bottleneck to the introduction.
Although the AN code has been certified, it is difficult to introduce it to the production side.

[0008]

On the other hand, in comparison with the one-dimensional bar code system, which is simply a combination of the space between the bars, the surface sensing is possible by a CCD camera or the like. The two-dimensional code system comes into the limelight due to various advantages such as direct input of information and good connection with a computer on the data processing side. For example, US Pat. No. 4,939,3
No. 54 invention, British patent No. 1249545 invention, JP-A-53-129533 invention, JP-A-57-191788 invention, JP-A-1-22223.
No. 93 invention, Japanese Patent Publication No. 2-268383, etc. The invention is developed and proposed worldwide, and it is a substantial prior application of the applicant, and it is also shown in Japanese Patent Application Laid-Open No. 53-12953. The so-called Carla code system, which is a character expression system of four boxes, has come into practical use.

[0009] Then, subsequently, there is a momentum for research and development of new matrix type two-dimensional codes which are excellent in practicality and low cost one after another.

Thus, in the matrix type two-dimensional code that has been (researched) developed so far, a large amount of the information amount is mainly pursued, and it is simply accumulated as an image. In order to improve the degree of miniaturization,
Although refinement has been attempted, for example, when sensing with a CCD camera or the like, it is necessary to capture the entire image frame and automatically recognize not only the entire image but also the unit image in the optimal posture state to process information. Therefore, there is a drawback that image processing and video processing are not clearly differentiated. For example, even if a spot-like image is enlarged in space, information processing in the entire image cannot be performed. It has a difficult difficulty, and also has a drawback that it lacks an index function for functional data to be extrapolated, and also has a drawback that the check digit function must be complemented.

Further, in the invention of the above-mentioned Japanese Patent Laid-Open No. 53-12953, there is no at least one position code in the address code, the start code and the end code, and therefore the bit code and the protect code are lacking. There was a hate that I couldn't complete.

In the invention of Japanese Patent Laid-Open No. 2-268383 mentioned above, the reference printing point as a position code is shown as an invention, but the address code, start code, end code and line feed code functions are clearly shown. There were some drawbacks.

And, the data of which the meaning is not clear is only specified in the arrangement of the reference print points.

Therefore, there is a minus point that the FA system cannot be widely put into practical use due to a serious obstacle to the standardization and the like of the FA system.

[0015]

The object of the present invention is to provide a conventional one-dimensional bar code based on the above-mentioned prior art and a two-dimensional bar code based on the conventional matrix system which has been developed to cope with the bar code. As a technical issue to be solved, surface sensing can be performed, and by using the automatic recognition technology developed so far, the image recognition posture can be achieved regardless of the conveyance of the object to be processed and the processing posture. Whether it is the entire picture frame or spot,
The matrix information in the columns can be scanned, the check digit function can be fully equipped, and the amount of data can be increased sufficiently.
It has a function code that can take in data from other extrapolations and also gives the ultimate interface language, and the potential of multilingualization. It is intended to provide a two-dimensional code sheet for information processing.

[0016]

In order to solve the above-mentioned problems, the structure of the invention of this application, which has the above-mentioned claims as its gist in accordance with the above-mentioned object, is arranged on the side surface of various kinds of objects to be processed. In a two-dimensional code sheet for processing (including information input / output disk and floppy disk), a unit block of a code of a predetermined size is arranged in a row and column system in a code display column of the sheet by a normal high thermal printing means. To be arranged in a matrix in a matrix including, in each unit block, a positive type in a plane in a mark zone of a predetermined shape which is formed by adjoining each other, or,
Negative type, and further, code mark including data code of both mixed type is displayed by printout or projection according to a predetermined marking rule in a mark sheet system.In this case, the code mark of the unit block is the head. part predetermined start code is formed, and the end code at the end portion, further, position codes such as line feed code is formed, in the meantime, taking technical means predetermined data code are then granted It is a thing.

[0017]

In the above structure, in the code mark of the unit block, between the start code of the head and the end code of the end part, and the position code such as a line feed code, etc., from another list outside the seat. Number of extrapolated bits, character code, English characters, Chinese numerals,
Mathematical equations, control data characters, information exchange codes, rule codes such as ASCII codes are inserted as function codes, and automatic recognition of the unit block is performed optically.
Even if the entire image frame of the input image is captured while being scanned by a CD camera or the like,
Even if a part of the matrix is photographed, the position of the scanning part in the matrix of the image is determined by the position code inserted in the data code of the matrix, and the matrix is calculated from the start code. The code data can be captured and started, and the processed product is processed as designed through computer processing.
