Description

  The present invention is an element cell that is a highly-integrated information code that is free to form and has excellent operability as compared to the conventional one-value and two-value code system, has a wide range of applications, and enables accurate information recognition. The present invention relates to a recognition code and a recognition code sheet for non-element cells.

  A representative example of the optically recognized encoding method is a bar code symbol character.

  In the JAN code (JIS-X-0501), the binary level bit code by 1-value recording in which the black bar is 1 and the white bar (space) is 0 is a unit module, and the numbers 0 and 1-9 are in units of 7 modules. One character.

  The binary level system module row that uses non-recording space (unrecorded background or blank area) as zero information is the unit module and double and triple black and white bars (spaces). The non-recording space is designated as a white bar by accurately recognizing the unit module that is synchronized with the time measurement and the code area indication code (code such as start and stop) that distinguishes the white bar from the general space. Things are needed.

  The error in the size of the black bar and white bar (space) by this binary level method is always correlated, and it is difficult to cope with the deformation of the code medium even if the recording accuracy of the black bar is strictly controlled, and the field of use is limited. Has been.

  The bar code of Code 39 and Coder Bar / NW-7 (JIS-X-0503) is composed of four types of code bars: a fine bar and a double bar of black and white (space) that is twice as wide as the fine bar. The idea of diverting space to two types of white bars remains the same.

  Even in highly integrated two-dimensional codes with bit codes as practical codes, the concept of recording and non-recording binary levels remains the same, and the areas, parts, and quantities of practical codes are determined by the huge amount of preset software and pattern recognition of redundant figures. , And a practical code is recognized according to a specified algorithm and is output in bits.

  The OCR (Optical Character Reader) method using character codes recognizes each character code as a pattern, compares a large amount of subdivided data with the basic data for each code, selects the information assigned to the character code, and outputs the bits. Depends on how you do it.

  There is a need for a highly integrated and reliable code and a recognition method with low redundancy for multiplicity of application fields.

  80 and 120 displayed in decimal numbers make it easy to omit eight picks, one hundred picks and empty positions (zero symbols) in Chinese characters, but 1010000 and 1111000 are omitted in binary code, and empty positions (zero symbols) are omitted. In the one-value display, it is difficult to determine the number of 11, 1111 and vacancies (zero symbols) at which position. Specify the code area and position, and ■■■■ □□□ indicate.

  In the barcode based on optical recognition, a recording black bar having a plurality of large and small widths and a non-recording white bar (space) are arranged, and it is impossible to recognize a unit bit without using an auxiliary method.

  The size error between the recorded black bar and the non-recorded white bar (space) always correlates. When the recorded black bar becomes thicker than the standard, the non-recorded white bar (space) becomes thinner, and conversely, when the black bar becomes thinner, it becomes white. The bar becomes thick and an error occurs in the count synchronization.

  If the code medium is deformed, the code standard is disturbed and it becomes difficult to cope with it.

  If the amount of data is increased, the code string becomes longer, and it is difficult to maintain a constant moving speed manually with an inexpensive pen reader, and recognition errors increase.

  In order to increase the reading accuracy, a highly accurate scanning system is required.

  Furthermore, the standard for the character connection quiet zone is strict, and data cannot be changed by additional writing, and even if a highly convenient code string with negative added is invented, it does not have a function to apply.

  Even in a highly integrated two-dimensional code where the practical code matches the computer binary code, the idea of binary level by recording or non-recording remains the same, and the area of the code is recognized by the huge amount of preset software and pattern recognition of redundant figures. In many cases, a recognition method using an image sensor consisting of two steps of specifying a position and quantity and recognizing and outputting a bit code according to a specified algorithm is used, and data change by additional writing is also impossible as with a barcode. .

  The character code for OCR is composed of a code string that can be additionally written that also represents a zero code, but there is a limit to space saving. Further, it is necessary to collate the pattern recognition data of each code with basic data, and it is difficult to improve the system easily.

  The present invention is characterized in that the unit module is multi-adic cell information in order to save data and to achieve high integration.

Unit cell may express element cell information from E ₁ by a positive or negative arbitrary multiple of the basic numeral basic numerals (including equal multiples) in a plurality of elements of En.

E represents a numeral information of the cell ₁ from any element of En by the synthesis of the element.

  However, in a cell expressing positive number information and negative number information, all number information may not be expressed in the cell depending on the base number. In this case, it depends on a combination with an adjacent cell.

Further, in the present invention, a set of element cell synthesized by a combination of En from E ₁ and saturated element cell Bs, characterized in that the saturated element cell Bs zero information.

  If there is a combined element cell with a combination of elements not corresponding to the cell number information and the saturated element cell Bs, the combined element cell is defined as a combined element cell B'o or B "o and is set as a function code.

And En element from E _1, N-ary number of the positive numeral information becomes element cell unit modules information synthesized by the combination, representing the negative numeral information and zero data.

  In the present invention, a portion that is not represented by an element cell is a non-element cell Bo and is a function code.

  The combination of the element cells to which the function code Bo is added becomes a recognition code in which the same kind of element cells are not continuous due to the role of the function code Bo, so that the recognition method becomes easy.

  Furthermore, according to the present invention, the redundant figure is omitted by the role of the function code Bo, and the synchronization of the count by time measurement becomes unnecessary.

  Furthermore, according to the present invention, data can be easily changed by additional writing due to the role of the function code Bo.

Hereinafter, the present invention will be described based on examples and drawings. FIG. 1A is a conceptual diagram showing an element cell and a non-element cell expressed by two types of elements E ₁ and E ₂ .

The E ₁ element cell 11 and the E ₂ element cell 12 express the numerical information of the cell, the composition 13 of the E ₁ element 11 and the E ₂ element 12 is a saturated element cell Bs, and the non-element cell (space) 14 is a function code Bo. And

  Thirteen synthesized saturation element cells Bs are element cells expressing zero information, and 14 non-element cells (spaces) Bo are function codes.

  FIG. 2-A is an N-ary matrix in which the basic number of each digit in N-ary is displayed as a power number (N times to the upper digit).

  FIG. 2-B is an N-ary matrix displaying the basic number of each digit in N-ary (N times the basic number 1 is the upper digit 1).

  The element cell of the present invention uses N-ary basic number 1 as basic element information, and uses any positive or negative multiple number element information of the basic number and numerical information by combining elements as N-ary element cell information.

  Zero information is expressed by a saturated element cell Bs, and a space is a non-element cell Bo unlike a conventional method used for information, and is used as a function code.

  The combination of a plurality of element cells represents the number of N-digit digits and the scale.

In the conceptual diagram of FIG. 1-B, when E ₁ element 11 is a basic number and E ₂ element 12 is a negative multiple of a basic number, E ₁ element 11 is the value information of the basic number of the cell, E ₂ element 12 is It can be the negative value information of the basic number. The synthesized element cell Bs13 is an element cell expressing zero information, and the non-element cell Bo14 is an element cell having a function code.

  In the binary matrix (FIG. 3-A) constituted by this element cell, the information on the negative number of the binary cell is also expressed without using the redundant bit or the complement conversion method by the conventional bit recording method.

  A combination of the binary element cell information and the number of digits and the scale by the power number display is as shown in FIG.

Since the ternary element cell of the ternary matrix of FIG. 3-C does not have the positive and negative doubling information of the basic number as shown in FIG. 1-B, the expression of the doubling information is the adjacent element cell. (2 = 10 ₃ −1, −2 = −10 ₃ +1).

4-A and 4-B are combinations of ternary element cell information, digit number, and scale with E ₁ element as a basic number and E ₂ element as a double number as shown in FIG. 1-C. Is illustrated.

  An embodiment (function 1) in which the function code of the non-elemental Bo14 is used as a trigger function between element cells will be described with reference to FIG.

  FIG. 17A is a partial view of a continuous combination of element cells in which an odd number of similar element cells are displayed adjacent to 181, 182, and 183.

  In the conventional coding method using a space as a sign, consecutive homogeneous codes recognize unit modules by time measurement or counting according to a specified method.

  In the present invention, the function code of the non-element cell Bo14 is the previous element cell instruction function code, and the same type of element cell 182 next to the element cell 181 of FIG. 17-A is converted into the non-element cell Bo14 and is displayed in FIG. Thus, it becomes a combination of element cells that do not have continuous element cells of the same type, and an easy recognition method that does not require time measurement or counting.

  In the continuous combination of element cells in which the even number of the same type of element cells in FIG. 18A are displayed adjacent to 191, 192, 193, 194, the next 192 element cell of the 191 element cell and the next 194 element cell of the 193 element cell 18B converted to the non-element cell Bo14 having the previous element cell instruction function code as the previous element cell instruction function code, the continuous combination of the same kind of elements is eliminated.

  However, when the 194 element cell is located at the end of the element cell combination matrix, a predetermined element cell end instruction code 196 is added.

5 _{E 21} element _{21, E 22} element _{22, E 23} element 23 and the synthetic element 24 representing the cell information is a conceptual diagram showing the saturation element Bs25 non element Bo14.

When a unit module is a multi-element element cell and the cell is expressed by three elements E ₂₁ , E ₂₂ and E ₂₃ , the element cell of each element becomes three types of cell number information.

The cell number information is expressed by an E ₂₁ element cell, an E ₂₂ element cell, an E ₂₃ element cell, and a composite element cell 24 by combining two types of elements.

  FIGS. 13 and 14 exemplify the element cell information of the decimal matrix by the maximum 15-digit element cell according to the conceptual diagram of FIG.

  In the conventional bit unit expansion, 4 bits (1/2 byte) are set to hexadecimal numbers. However, the use of the 15-element element cell of the present invention facilitates recording and calculation of time and period in the hexadecimal system.

Binary binary display unit digits are expressed in bits, but ternary ternary unit digits are expressed in bit three (Bit ₃ ) and the same digits (bit and bit ₃ ) are recorded. As shown in the data volume comparison table of FIG. 15, when the number of bit digits or the number of bytes (in units of 4 digits) is increased, the data magnification becomes an astonishing number. The binary bit unit recording method has a much larger amount of data.

It is possible to express information with graphics or the like.

  Furthermore, since the features of the present invention can be configured by elements and non-elements having a free size and a free shape, information can be formed into an arbitrary shape using the elements and non-elements (FIG. 19-D). ) The visual language for humans and the information language for computers can be expressed simultaneously, and the application fields of the system are greatly diversified.

  By making the figure or the character shown in FIG. 20 partially divided into element cell parts and non-element cell Bo parts, the visual language and the computer language can be easily combined. In addition, it is possible to perform scanning that is simple and excellent in operability with an inexpensive pen type sensor, and becomes a space-saving recording method in which two languages are not written side by side.
