Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bar code notation device for characters and a reader for reading bar coded characters.

[0002]

[Prior art]

 Recently, it has been attempted to provide a digital data recording unit on a business card and directly input the contents of the business card into a computer to make address book organization extremely simple. There have been attempts to use barcodes as the recording section, but it is necessary to barcode not only numbers such as telephone numbers but also Chinese characters such as addresses and names. In this case, conventionally, a code with a large amount of expression per unit is newly created to directly express the JIS Kanji code. In addition to this, a bar code called Code 5 of 10 has been proposed as a method that can convert all JIS 6226 and Shift JIS kanji with real codes.

[0003]

[Problems to be solved by the device]

 When considering and using the above-mentioned new code, since the used code is not common, a special reading device is required and it is difficult to spread. Further, Code 5 of 10 has a problem that the code system is not open to the public and the decoder IC has not been put on the market. Therefore, the object of the present invention is to spread all characters up to JIS level 2 using the ITF bar code, which has a sufficiently wide spread, has a short symbol length, and can be used by existing bar code readers. The purpose is to provide a bar code notation device and a reading device therefor.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the bar code notation device according to the present invention converts an input character into a hexadecimal JIS code and an output from the input conversion unit into a decimal number. At the same time, it is composed of control means for outputting the image data of the ITF bar code corresponding to this numerical value, and printing means for receiving the output of the control means and forming the ITF bar code on the recording medium. An ITF bar code reader on a recording medium formed by the above-mentioned device converts a bar code reading means and a decimal number read by the bar code reading means into a hexadecimal JIS code, and converts this. It is composed of control means for reading characters corresponding to the JIS code from the font ROM and display means for displaying the characters read from the font ROM. Further, in the reading device, a printing unit may be used instead of the display unit.

【Example】

 The JIS code is represented by a 4-digit hexadecimal number, and as non-Kanji characters for information exchange, 524 non-Kanji characters, 1st level Kanji characters 2965 characters, and 2nd level Kanji characters 3385 are the first bytes 21 to 7E and the second bytes. 21 to 7E. That is, non-Kanji 524 characters are in the first bytes 21-28 and second bytes 21-7E, first level Kanji characters 2965 are in the first bytes 30-4F, second bytes 21-7E, and second level Kanji characters 3385 are It is specified in the first byte 50 to 74 and the second byte 21 to 7E. Since 8836 characters can be represented in the first bytes 21 to 7E and the second bytes 21 to 7E, it is sufficiently possible to represent them in decimal.

Therefore, in the present invention, the interleaved 2 of 5 (ITF bar code), which is a bar code having a large amount of expression per unit and a high diffusion rate, is used to convert the hexadecimal JIS code into a decimal number. And the numerical value converted into the decimal number is expressed in ITF bar code.

In this embodiment, non-kanji characters, first level kanji characters, and second level kanji characters are divided into three areas and are evolved into 10 areas, and are expressed by 4-digit decimal numbers. Therefore, the above three Kanji areas are defined as non-Kanji areas 0000 to 0999, first level Kanji areas 1000 to 3999, second level Kanji areas 4000 to 7999, and 8000 to 9999 are reserved for future expansion.

In the conversion formula described below, JISC represents a JIS code and ITFC represents an ITF code. Hi represents a numerical value in which the first byte of the JIS code is represented by a decimal number, and Lo represents a numerical value in which the second byte of the JIS code is represented by a decimal number. The operators "/" and "%" indicate integer division and remainder calculation. Furthermore, (16) and (10) indicate that they are a hexadecimal number and a decimal number, respectively.

Therefore, first, the case of converting from a JIS code into a decimal number value represented by an ITF barcode will be described. The conversion formulas for the three types of characters are as follows. The conversion formula (1-1) of non-kanji is ITFC = (Hi-33) × 94 + (Lo-33) The conversion formula (1-2) of the first level kanji is ITFC = (Hi-48) × 94 + ( Lo-33) +1000 The conversion formula (1-3) of the second level Chinese character is ITFC = (Hi-80) × 94 + (Lo-33) +4000. Here, 33 is a numerical value obtained by converting 21 (16) into a decimal number, 48 is a numerical value obtained by converting 30 (16) into a decimal number, and 80 is a numerical value obtained by converting 50 (16) into a decimal number. is there.

As an example, a case of obtaining the decimal value of the first level kanji “sei” will be described. The JIS code for "fine" is 403A, the first byte is 40, and the second byte is 3A. Therefore, Hi = 40 (16) = 4 × 16 = 64 (10) Lo = 3A (16) = 3 × 16 + 10 = 58 (10), and from the above conversion formula (1-2), ITFC = (64-48) X94 + (58-33) + 1000 = 16x94 + 25 + 1000 = 2529. Therefore, the JIS code 403A of the Chinese character "sei" is converted into the decimal number 2529. Similarly, the kanji "Kou" is JIS code 3929, and the conversion formula (1-2) gives a decimal value 1854. Further, the kanji "sha" is JIS code 3 C4B and the conversion formula (1 -2) is converted into a decimal number 2170. Therefore, the kanji character string “Seikosha” is converted into the decimal numeral string “252918542170”, and the ITF bar code is displayed as shown in FIG. In this embodiment, a four-digit decimal number is obtained, but a numeric value obtained by simply converting the JIS code into a decimal number may be displayed by an ITF bar code. It is desirable to use even digits by adding "0" to the end of the base number.

Next, an apparatus for performing the above conversion and writing characters by a bar code will be described with reference to FIG. Reference numeral 1 denotes an input conversion means, which converts a JIS code by inputting a character and supplies the output a to the control means 2. The input conversion means 1 may be of any type as long as it provides a JIS code as an output, and examples thereof include a kana-kanji conversion device, a kanji input tablet, and an OCR device. The control unit 2 includes a CPU 21, a RAM 22 and a ROM 23, and the ROM 23 stores the control program and the conversion formulas (1-1), (1-2), (1-3) described above. Has been done. When the output a is supplied to the control means 2, the JIS code is converted into a decimal number by the above conversion formula, and this value is further converted into the image data of the ITF barcode, and this output b is printed by the printing means. Supply to 3. Upon receiving the output b of the control means 2, the printing means 3 forms an ITF barcode on a recording medium (not shown).

When the image data of the ITF barcode is built in the printing means 3, the control means 2 supplies a decimal number value to the printing means 3 as an output b. The printing means 3 receives this output b, converts it into image data of an ITF barcode, and prints it on a recording medium (see FIG. 1).

Next, with reference to FIG. 3, a reader for reading an ITF barcode on a recording medium formed by the above-mentioned device will be described. A bar code reading means 4 reads the image data of the ITF bar code and supplies its output c to the control means 5. The bar code reading means 4 may be of any type such as a pen type reader or a touch scanner. The control means 5 includes a CPU 51, a RAM 52, and a ROM 53. The ROM 53 stores a control program and the following conversion formulas (2-1), (2-2), (2-3), etc. There is.

A conversion formula for converting a decimal number expressed by an ITF barcode into a JIS code is as follows. The conversion formula (2-1) for non-kanji is Hi = ITFC / 94 + 33 Lo = ITFC% 94 + 33 JISC (10) = Hi × 256 + Lo The conversion formula (2-2) for first level kanji is Hi = (ITFC-1000). ) / 94 + 48 Lo = (ITFC-1000)% 94 + 33 JISC (10) = Hi × 256 + Lo The conversion formula (2-3) of the second level kanji is Hi = (ITFC-4000) / 94 + 80 Lo = (ITFC-4000). % 94 + 33 JISC (10) = Hi × 256 + Lo.

It should be noted that the JISC (10) is converted into a hexadecimal JIS code by dividing Hi and Lo by 16 respectively, and setting the integer as a high-order number and the remainder as a low-order number. It is a hexadecimal JIS code.

As an example, a case where a decimal number 1854 is converted into a JIS code and the character is obtained will be described. Since the numerical value 1854 is between 1000 and 3999, it is converted to the first level kanji. From the above conversion formula (2-2), Hi = (1854-1000) / 94 + 48 = 854/94 + 48 = 9 + 48 = 57 Lo = (1854-1000)% 94 + 33 = 854% 94 + 33 = 8 + 33 = 41 JISC (10) = 57 It is x256 + 41 = 14633 (10).

When this is converted into a four-digit hexadecimal JIS code, the first byte is 57 ÷ 16 = 3 remainder 9 = 39 (16) The second byte is 41 ÷ 16 = 2 remainder 9 = 29 ( 16) Therefore, the JIS code corresponding to the decimal number 1854 is 3929, which is defined as the Chinese character “K”.

When the output c is supplied to the control means 5, the image data of the bar code is converted into a decimal number value, which is further converted into a JIS code by the above conversion formula, and this output d Is supplied to the display means 6. Also, the output d of the control means 5 is supplied to the font ROM 7, the character corresponding to this JIS code is read from the font ROM 7, and this character is displayed on the display means 6.

When the bar code reading means 4 is of a decoder built-in type, the image data of the ITF bar code is converted into a decimal number and the output c is supplied to the control means 5.

As the display unit 6, a CRT, LCD, LED or the like is appropriately used. It should be noted that instead of the display means, a printing means may be arranged to print the character corresponding to the read ITF barcode on the recording medium. Further, instead of the display means, the output d of the control means 5 may be supplied to a storage means such as an IC memory or a magnetic storage device or a communication means such as an RS-232C line or an IEEE standard bus.
