- the key dots 2 are dots arranged at both ends of a set of fixed information as shown in FIG.
- the key dot 2 is a representative point of the dot pattern 1 for one region representing a group of information dots.
- the representative point may be arranged anywhere in the group of information dots. For example, if the interval between adjacent reference dots is 0.5 mm, the reference dot 4 at the end of the area of the dot pattern 1 is arranged at a position shifted by 0.1 mm upward from the position where it should originally be arranged. . Therefore, when the information dot 3 is defined by the X and Y coordinate values from the reference dot 4, the position at a distance of 0.1 mm below the key dot 2 is the coordinate point.

On the contrary, if the distance between the information dot 3 and the virtual reference point 5 is longer than this distance, it is determined whether the information dot 3 has the vector direction around one of the adjacent virtual reference points 5. This is because it becomes difficult.
- the dot pattern according to the present invention is read by an optical reading means (for example, a camera or a scanner), and the dot pattern of a predetermined position, a predetermined region, or the entire region is read by being brought into contact with or separated from the medium surface, or formed in a linear shape. This is done by tracing and reading the dot pattern.

- the information dot 3 if two types of short (upper part in FIG. 3) and long (lower part in FIG. 3) are used from the virtual reference point 5 derived from the reference dot 4 and the vector direction is eight directions, then 4 bits. Can be expressed. At this time, it is desirable that the longer one is about 25 to 30% of the distance between adjacent virtual reference points 5, and the shorter one is about 15 to 20%. However, it is desirable that the center interval between the long and short information dots 3 is longer than the diameter of these dots.
- the information dot 3 is preferably one dot in consideration of its appearance.

- FIG. 28 is a diagram illustrating an example of obtaining the center XY coordinate value obtained by imaging the dot pattern by the optical reading unit.
- the coordinate value of the coordinate center of the dot pattern is obtained.
- the representative point coordinate value of the dot pattern in which one coordinate value is defined is (X 0 , Y 0 ) in the dot coordinate system and (x 0 , y 0 ) in the imaging coordinate system.
- the increment value of the X coordinate value of the dot coordinates is Kx and the increment value of the Y coordinate value is Ky
- the coordinate values adjacent to (X n , Y n ) are (X n + 1 , Y n).
- the value of +1 ) can be expressed as the following equation. Therefore, the XY coordinate value of the imaging center is expressed by the following formula.
- n is the number of reference dots from the beginning of a plurality of reference dots that define a set of coordinate values to the beginning of the reference dot that is defined by the coordinate values that are successively arranged next.
- ⁇ is a coefficient for indicating the increment value of the imaging coordinate system y coordinate with respect to the distance ⁇ x between the reference dots of the imaging coordinate system of the dot pattern, that is, ⁇ x is the increment value of the dot coordinate system Y coordinate.
- ⁇ x is the increment value of the dot coordinate system Y coordinate.
- a code value may be defined in the area where the Y coordinate value is defined.
- a Z coordinate value can also be defined, whereby a three-dimensional coordinate can be expressed.
- the height can be read at any position on the map, and further, if dots are printed on the surface of the solid, the shape of the solid can be read and reproduced.
- Ink used for dot printing of stream dot pattern is stealth ink (invisible ink) that absorbs infrared rays or carbon black, and ink used for normal graphic and text printing is non-carbon ink that reflects or transmits infrared rays. Is desirable.
- the dot pattern is composed of extremely small dots with a diameter of 0.04mm (about 0.05mm for inkjet printers) and is difficult to see. Using colorless and transparent infrared absorbing stealth ink developed for high-quality output makes the dots completely invisible. It is also possible to do.
- the information dot is usually provided at a position equidistant from the virtual reference point in order to make the dot inconspicuous, but if you want to express the information not only in the direction but also in the length and accurately recognize the information dot, Information may be defined by different distances for each virtual reference point.
- CMYK K carbon black
- CMY may be used for CAD drawings, characters / symbols / graphics, maps, photographs, and graphics, and dots may be printed thereon with K.
- the black color is expressed as composite black by mixing 100% of CMY.
- perfect black cannot be reproduced, black may not be emphasized and the picture may not be tightened.
- the area where dots are printed is dot-like because the dots are printed with K, and if you look closely, it will be a light grayish pattern. In order to solve this, it is only necessary to print dots only in the minimum necessary area and use CMYK in the area where dots are not printed as usual. However, the scanner can be touched only in a limited area where dots are printed.
- ink that reacts in the infrared region cannot be used for copying, security can be maintained at a high level.
- printing media regardless of the type of paper to be printed, dot printing is possible on any paper, such as art paper, matte paper, high-quality paper, plain paper, newspaper, photographic paper, printer paper, etc. Other than paper, any medium that does not expand or contract can be printed.
- a scanner that reads dot codes can process from dot pattern shooting to dot code analysis in just 0.1 to 0.2 seconds, and can access information instantly without stress.
