2. Description of the Related Art In the former known technology of Japanese Patent Laid-Open No. 57-14263, a rectangular code display frame (display area) is used for optically reading a signal code recorded on a base cloth for article identification display. There is no technical idea to read the position and range. The latter known art of Japanese Patent Laid-Open No. 53-73026 discloses means for detecting the range of the display area by displaying a position mark before and after the display area to clearly indicate the range of the display area in the longitudinal direction. Does not disclose any technical means for detecting the vertical range of the display area. When reading the information recorded on the identification code paper as alphanumeric and Chinese characters, etc., use a line sensor, C
A binary signal code recorded on an identification code sheet is detected by a CD camera, and the binary signal code is converted into a JIS code by image processing and data processing by a computer and output and displayed as an alphanumeric kanji symbol or the like. In image processing and data processing by this computer,
The read data of the binary signal mark is always processed in the memory of the computer, and the data displayed on the paper, the surface of the article or the like is not directly recorded in the memory. Therefore, there are the following problems. The memory for data processing naturally has the capacity of the memory, and the data area cannot be limited from the code itself from an unspecified wide range like the human eye. For example, even if data (for example, a binary signal mark) is printed on the coordinates orthogonal to the line, the difference in the reading direction and the difference in the reading speed (the movement direction of the line sensor is different from the coordinate X-axis direction). In some cases, if the DDC camera is misaligned vertically and horizontally with respect to the front facing position of the identification code paper, if the product surface with the identification code paper attached is a curved surface, the product with the identification code paper attached and the line sensor. Depending on the relative movement speed with
In reality, it is often the case that the processed data and the image processed data do not always match. Therefore, it is possible to identify the area to be image-processed in the memory and to reliably determine the position of each data area to be image-processed in the memory (not on the printed paper). This is the most important issue for improving the reading error rate and putting this type of identification code paper into commercial use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on the embodiments shown in the drawings. The code surface B of the present invention is printed and displayed at an appropriate position on the identification code paper A, but the printing direction and the number thereof are arbitrary. In the code surface B of the present invention, the shape and area of the display area b 1 are determined by the X-axis base line 1 and the Y-axis base line 2. FIG. 2 shows various display areas b, and the object of the present invention can be achieved if at least 16 unit data areas (subsections) 3 can be formed. (A) The figure is one step
6 pieces are arranged in the horizontal direction, (b) figure is 2 steps and 8 pieces are arranged horizontally in each step, (c) figure is 4 steps and 4 pieces are arranged in each step horizontally and the display area is shown. Square, (d) Figure and (e)
The drawing is obtained by turning the embodiment shown in FIGS. (B) and (a) by 90 degrees, and the display area is a vertically long rectangle.

For 16 unit data areas 3,
Referring to FIG. 3, addresses are designated in an appropriate order (P ₁ P ₂
... _{P 16),} the further embodiment is divided into four at a time four groups _{(P 1 ~P 4, P 5} ~P 8, P 9 ~P 12, P
_{13 to} P ₁₆ ), four medium data areas 4 are formed, and binary signal marks (binary signals) are recorded and displayed in each unit data area 3 to obtain 2 ¹⁶ (OOOO to FF).
FF) binary code can be recorded and displayed. 16
The method of dividing the individual unit data area 3 into four groups and the arrangement order in the middle data area 4 are arbitrary, and can be appropriately changed under the control of the microcomputer printer.
For example, (P ₁ , P ₆ , P ₁₁ , P ₁₆ ; P ₅ ,
P ₁₀ , P ₁₅ , P ₄ , P ₉ , P ₁₄ , P ₃ , P ₈ ; P
₂ , P ₇ , P ₁₂ , P ₁₃ ) (P ₁ , P ₅ , P ₉ , P)
₁₃ ; P ₁₄ , P ₁₅ , P ₁₆ , P ₁₂ , P ₈ , P ₄ ,
P ₃ , P ₂ ; P ₆ , P ₁₀ , P ₁₁ , P ₇ ) (P ₁ ,
_{P 2, P 6, P 5} , P 3, P 4, P 8, P 7, P 11;
P ₁₂ , P ₁₆ , P ₁₅ ; P ₉ , P ₁₀ , P ₁₄ , P
₁₃ ) and other various combinations are possible. As the binary signal mark k for recording and displaying the binary signal in each unit data area 3, it is not necessary to completely fill the unit data area 3 as shown in FIG.
(C) As in (d), a blank portion is left in a part of the unit data area 3 and other marks (for example, a circle for b, a star for c, a triangle for d, etc.) are used for the purpose of the present invention. Can be achieved. Further, the above-mentioned marking method is not limited as a signal display method of the binary signal of the unit data area, and a perforation method or a magnetic writing method can be considered as a method capable of obtaining the same effect.

Further, in the embodiment, as shown in FIG. 5, an extended X axis base line 11 and an extended Y axis base line 12 are added to set an auxiliary display area d and an auxiliary display area d.
The auxiliary mark 5 is recorded and displayed at an appropriate position (in the embodiment shown by the solid line in FIG. 5, a diagonal position with respect to the 0 point of the X axis base line and the Y axis base line). The auxiliary mark 5 is not limited to a square shape, and may be ◯, ☆, +, − or any other mark whose presence can be identified. Also, as shown in FIG.
If the horizontal division line 6 and the vertical division line 7 are printed and displayed in addition to the X-axis base line 1 and the Y-axis base line 2, each unit data area 3 can be printed with an appropriate writing tool without printing with a microcomputer printer.
By filling in or displaying a circle mark etc.,
It is convenient that the signal code can be determined at the site where the identification code string is applied.

When the code surface B is printed on the identification code paper A, it can be printed by a general printing means, but a 16 or 24 dot personal computer printer or a handy computer printer which is normally commercially available at present. You can also print out using. In this case, character strings (product name, department name, address name, telephone number, etc.) and sentences (messages, advertisements, etc.) are converted into binary signals according to JIS code by PC processing, and each character is converted into 2
One display area b of ¹⁶ signal codes can be made to correspond, and when the letter L corresponding to the adjacent area (for example, the lower side) of the display area b displayed in binary code is displayed, the product name and the person in charge It is convenient that you can display the kanji at the same time as coding. (See Fig. 8)

Further, the position designation of each address P ₁ , P ₂ ... P ₁₆ of the ₁₆ unit data areas 3 and each group Q ₁ , Q ₂ , Q ₃ , Q ₄ of the middle data area ₄ are selected. If the designation of the unit data area 73 to be changed can be freely changed by the microcomputer control (the letter L in FIG. 8 is deleted),
It is convenient that you can add the cost to the product code and password of various cards can be encrypted and used for encryption number. In reading the identification code sheet of the present invention, the line sensor is moved in the vertical direction or the horizontal direction to send a read signal to the personal computer, and the personal computer calculates the X-axis base line 1 and the Y-axis base line 2 to display the display area. By identifying b, the position of each unit data area 3 and each middle data area 4 in the display area b and the presence or absence of the binary signal mark at each position are image-processed to identify the product. The code can be read and the specified kanji can be printed out based on the JIS code. By reading the X-axis base line 1 and the Y-axis base line 2 of the identification code sheet, the display area b is recognized in the memory of the computer at the position / range that matches the display area b of the identification code sheet, and the display area b is displayed. It is possible to detect the binary signal mark displayed on the display corresponding to a predetermined unit data area of the identification code sheet.

That is, when the identification code sheet is read by the line sensor, if the line sensor moves in the direction of the X-axis base line 1 of the identification code sheet and the longitudinal direction of the identification code sheet coincides with the movement direction of the line sensor, the computer The display area b in the memory has its X-axis baseline aligned with the X-axis baseline 1 of the identification code paper, but the line sensor is displaced in the direction of movement or the product sticking position of the identification code paper is vertically or horizontally displaced. The display area in memory b
Can be dealt with by rotating the X-axis baseline of the display area b in the memory by image processing so that the X-axis baseline coincides with the direction of the X-axis baseline 1 of the identification code paper. Further, the length of the display area b in the memory in the X-axis direction is the standard for the change in the length in the X-axis direction of the display area b in the memory due to the change in the moving speed of the identification code paper or the moving speed of the line sensor. Can be dealt with. The Y-axis baseline direction of the display area b corresponds to the display area b in the memory in the same manner as in the X-axis direction described above. In addition, when the DDC camera reads the identification code sheet, the DDC camera is displaced vertically and horizontally with respect to the front facing position of the identification code sheet, and when the product surface to which the identification code sheet is attached is a curved surface, it is stored in the memory. In order to match the X-axis baseline of the display area b with the direction of the X-axis baseline of the identification code paper, the X-axis baseline of the display area b is rotated by the image processing of the computer.

Furthermore, when there is a difference in the vertical and horizontal directions when attaching the identification code paper to the product, or when the relative movement direction of the product to which the identification code paper is attached to the sensor is different, the X-axis base line and Y This can be dealt with by rotating the display area b with the origin 0 intersecting with the axis base line as a reference to match the X axis base line in the memory with the X axis base line 1 of the identification code paper. When the X-axis base line and the Y-axis base line intersect at a point other than the origin 0, that is, by eliminating the T-shaped intersection as an error, H (black coloring) in the display area b is displayed.
In order to prevent an erroneous recognition error of the range / position of the display area b by erroneously recognizing a vertical line or a horizontal line generated by the continuous binary signal mark of 1) as a Y-axis base line or an X-axis base line, If the X-axis base line and the Y-axis base line intersect at a point other than the origin 0, it is excluded as an error. In the embodiment, the extension X-axis baseline 11 and the extension Y-axis baseline 12 detect the auxiliary display area d and how to detect the position and range of the display area b by the X-axis baseline 1 and the Y-axis baseline 2 described above. it can. Further, in the embodiment in which the auxiliary area mark 5A is displayed at the position opposite to the origin 0 in the auxiliary display area d, the X axis base line 1, the extended X axis base line 11,
By determining the position and range of the display area b and the auxiliary display area d by the surroundings of the Y-axis base line 2, the extended Y-axis base line 12, and the auxiliary area mark 5A, the display area b and the auxiliary display area d by the image processing of the computer are determined. The location and range of can be shortened and the memory capacity of the computer can be reduced.

For the above reasons, in the present invention, X
By reading the axis base line 1 and the Y-axis base line 2, the reading direction of the sensor can be determined by a computer by a calculation process, and thus the reading direction of the line sensor may be any of up, down, left and right. Further, in the embodiment in which the auxiliary display area d is provided and the auxiliary mark 5 is attached, the judgment processing of the sensor reading direction by the personal computer becomes easy. In other words, even if the sensor is read from the wrong direction, accurate reading is possible by computer processing (generally, it is said that the barcode cannot be read if the reference reading direction deviates by 45 ° or more).
When reading by pasting on the object to be read, for example, if the object to be read flows on the conveyor, regardless of the direction of the pasting or the direction of the object to be read (shift from the normal sticking direction, Accurate interpretation is possible even if the relative position of is incorrect.

A normal string can be used as the identification code paper. That is, in the case of a bar code, it is necessary to use expensive special paper because a reading error may occur due to expansion and contraction of the line, but it is sufficient to detect the presence or absence of a binary signal code in each unit data area of the display area. Therefore, it is sufficient to print on normal paper and print out. Further, even if the size of each code is different, since the binary code is read in the display area within the base line, it can be read without any problem. Furthermore, it is possible to print on plastic films other than paper, product containers, etc. Also, by recording with transparent magnetic ink on the printed paper, film, etc., it is recorded on top of the usual printed display. You can also

The present invention can also be output by a personal computer printer or the like, and if a handy computer printer is used, it is possible to immediately change the code contents on the spot, such as when a time-based discount is made at a supermarket or the like. There is an advantage that it can be handled and there is no need to perform data master maintenance of the host computer. In addition, even if the data entry to the computer is extremely troublesome work (for example, a person's name, place name, address, etc.), if the same contents as the data are written in advance on this identification code sheet, it can be easily entered ( If you want to input data such as a part of the contents of a book or printed matter or a relatively long sentence without needing to perform individual master registration or searching for data with the host computer, you can directly input from the printing paper without entering with the keyboard. ). Further, when a sentence is expressed, one character in the sentence becomes one code, so that the number of characters is the same and it is possible to print in parallel. For example, referring to FIG. 8, four display areas b
"4267", "3A65", "4240", which are JIS kanji codes corresponding to "large", "saka", "thick", and "ro"
The present invention is applied to "4F4A" to record a binary signal code, and "large", "saka", "thick", and "ro" are displayed in parallel therebelow.

In the above embodiment, the case where there are 16 unit data areas has been described, but the unit data areas are multiples of 4, such as 20, 24, 28.
The number of unit data areas for each medium data area can be 5, 6, 7 ... (In this case, the number of unit data areas for each medium data area is 4, and the number of groups is 5, 6). , 7 ...)
See FIG. The number of unit data areas is an integer multiple of 16, and the number of unit data areas for each medium data area is an integer multiple of 4 (or the number of groups is an integer multiple of 4).
Can also be Further, assuming that the number of unit data areas is 2 ″ and n = 5, that is, 2 ⁵ = 32 unit data areas, one identification code is OOOOO ... VV.
Characters can be expressed by a combination from VVV 2 ³² = 4.2
The number of characters is increased to 94968 × 10 ⁹ . Furthermore n
= 6, 7, ..., The number of character types that can be displayed by one identification code increases by 2 ² exponentially (first
(See Figure 0). The number of medium data areas is 2 ^m [m =
n-2], the number of m also increases as n increases, and the number of medium data areas can be exponentially increased. That is, in the embodiment, m = 2 is used to divide into four groups, but n = 5.
In the case of, m = 2 (2 ² = 4), m = 3 (2 ³ = 8)
Therefore, it can be divided into 8 groups in addition to 4 groups. n = 6
In the case of (the number of unit data areas is 64), m = 4 (2 ⁴ = 16) in addition to the above 4 groups and 8 groups.
It can also be divided into 16 groups.
