Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for representing special characters in an information processing device having a document creation function, such as a word processor.

[Prior art and its problems] Conventionally, in information processing devices with document creation functions such as word processors, in order to output a special character such as "■", it is necessary to output a special character that corresponds to the kanji code of the special character. It had to have a character pattern. That is, it was necessary to register in advance all the character patterns of kanji codes for special characters frequently used in document creation.

Alternatively, a single character pattern of a single character was synthesized using a two-character kanji code and a preset special code. For example, ro 127, which is the kanji code for "○"
"■" was synthesized from J, a preset special code, and ro 317J, which is the kanji code for "1".

Or, use the first character of two characters as a special code to make one sentence -
I was synthesizing character patterns. For example, the special code for rOJ and a special code set in advance to be combined with the next code, and the kanji code for "1" for ro.
317J, "r■" was synthesized.

However, these combination methods have the disadvantage that since the display or print columns and the memory size are different, any program that handles the data must perform extra processing.

[Objective of the Invention] The present invention has been made in view of the above points, and it is possible to match characters that are frequently used and are expressed by combining two characters by matching the display and print columns with the size in memory. The purpose of this invention is to provide a method for expressing special characters that can be expressed in

[Summary of the Invention] In order to achieve the above-mentioned object, the present invention is expressed by combining graphic characters such as "○" and "1 mouth" with characters that can be expressed in one byte such as alphanumeric characters and katakana. Codes for special characters such as "■" are composed of preset 1-byte codes corresponding to graphical characters such as "○" and 1-ku, and 1-byte codes corresponding to the alphanumeric characters and katakana characters listed above. It is characterized by being expressed using a 2-byte code.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, numeral 10 is a display character register that stores the supplied 2-byte Kanji code. In this case, the upper 1 byte of the above Kanji code means, for example, roj (FE
) 1e or (FD)l B, which means 1 unit, is a preset special code, and the lower 1 byte is an EBCD code such as alphanumeric characters or katakana that can be expressed in 1 byte.
This code is a C code or an ASCII code (hereinafter referred to as an alpha code). In other words, using the EBCDIC code
If □, “■” is (FEF 1) 1a,
rQJ' is (FECI) 1s, 1 mouth' is (F
D81) Kanji code expression such as 1e. In this way, the display character register 10 stores kanji characters as codes for characters expressed by combining alphanumeric characters, katakana characters, etc. that can be expressed in one byte, and graphic characters such as "○" and "mouth". A 2-byte code equivalent to one character is stored.

12 in the figure is a special code table, in which special codes and kanji codes correspond.

14 is a comparison circuit which compares the upper one byte of the Kanji code stored in the display character register 10 and the special code in the special code table 12. 16
is an AND circuit which takes the Kanji code of the special code table 12 as one input and the output of the comparison circuit 14 as the other input. Further, 18 is an AN having one input as the kanji code stored in the display character register 10 and the other input as the inverted output of the comparison circuit 14.
This is the D circuit. Reference numeral 20 denotes an OR circuit having one input as the output of the AND circuit 16 and the other input as the output of the AND circuit 18.

22 is a display character register that stores the output of the OR circuit 20. 24 is a kanji code/character pattern conversion circuit for converting the kanji code stored in the display character register 22 into a font pattern for display or printing.

Further, 26 is an alpha code/kanji code conversion circuit for converting the lower 1 byte of the kanji code stored in the display character register 10, that is, the alpha code, into a 2-byte kanji code.

28 is the alpha code/kanji code conversion circuit 26
This is a kanji code/character pattern conversion circuit for converting kanji codes converted into font patterns. 3
0 is a character reduction circuit for reducing the font pattern converted by the Kanji code/character pattern conversion circuit 28 by about 20%.

32 is an AND circuit which takes the output of the character reduction circuit 30 as one input and the output of the comparison circuit 14 as the other input. 34 is an OR circuit which takes the output of the AND circuit 32 as one input and the output of the Kanji code/character pattern conversion circuit 24 as the other input. Note that 36 is a character generator RAM (hereinafter referred to as CGRAM), 38 is a display control circuit, and 40 is a CRT display.

In such a configuration, the display character register 10
There are two types of operations: one when the Kanji code supplied to the character is a Kanji code corresponding to a special character, and the other when it is a normal Kanji code. The operation in the case of Kanji codes corresponding to special characters will be explained below. That is, a preset 2-byte Kanji code corresponding to the special character is stored in the display character register 10. Then, the upper 1 byte of the stored Kanji code, that is, the special code, and the special code table 12
The contents of are compared in the comparison circuit 14. In this case, special codes are supplied to the comparison circuit 14 in order from the beginning of the special code table 12, and the Kanji code corresponding to the special code is supplied to the AND circuit 16.

For example, when (FD) 1B is supplied to the comparison circuit 14, (2222) IB is supplied to the AND circuit 16.
is supplied and (GFE) 18 is supplied, the AND circuit 16 is supplied with (217B) 1s.

As a result of the comparison, if equal codes exist, the output of the comparison circuit 14 becomes "high". Therefore, the kanji code corresponding to the matched special code becomes the output of the AND circuit 16, and is supplied to the OR circuit 20. In this case, one input of the AND circuit 18 is "
Therefore, there is no output from the AND circuit 18. Therefore, the output of the OR circuit 20 is the output of the AND circuit 16.
This is the kanji code supplied by the user. This Kanji code is stored in the display character register 22, and converted into a font pattern by the Kanji code/character pattern conversion circuit 24. This font pattern is the same as the above OR
One side of the circuit 34 is supplied with human power.

On the other hand, the lower 1 byte of the Kanji code stored in the display character register 10 is converted into a 2-byte Kanji code by the alpha code/Kanji code conversion circuit 26. Then, the Kanji code is converted into a font pattern by the Kanji code/character pattern conversion circuit 28. The font pattern is further changed to the above character reduction circuit 3.
0, it is reduced by about 20%. This reduced font pattern is supplied to one of the AND circuits 32. In this case, the other input of the AND circuit 32 is "high"
Therefore, the reduced font pattern is supplied as is to the other input of the OR circuit 34.

Subsequently, the OR circuit 34 outputs a composite font pattern of the output caffondo pattern of the kanji code/character pattern conversion circuit 24 and the output cuffondo pattern of the character reduction circuit 30, and this composite font pattern is written into the CGRAM 36. Therefore, the above CR
The T display 40 shows ■, ■, ..., [! ],
-0 where special characters such as 口, . That is, the 2-byte kanji code is stored in the display character register 10.
is stored in Then, the upper 1 byte of the stored Kanji code and the contents of the special code table 12 are as follows.
The comparison circuit 14 compares them and checks whether they match.

As a result of the comparison, if no equal code exists, there is no data output from the AND circuit 16, and the data from the AND circuit 18, that is, the contents of the display character register 10, becomes the output of the OR circuit 20 as is. It is stored in the display character register 22. The Kanji code, which is the content of the display character register 22, is converted into a font pattern for display or printing by the Kanji code/character pattern conversion circuit 24.

In addition, since the output of the AND circuit 32 is also "0",
The output of the Kanji code/character pattern conversion circuit 24 is written as is into the CGRAM 36 and displayed on the CRT display 4o.

In this way, characters that can be expressed by combining alphanumeric characters, katakana, etc. that can be expressed in 1 byte, and graphic characters such as O2 mouth are expressed in 2 bytes, which is the same as 1 Kanji character, and the above display characters are expressed. By storing the special characters in the register 1o, the special characters can be output (displayed, printed).

Note that as a manual method using a keyboard (not shown), any unused keys are used. For example, in order to input ``1 kuchi'', it is conceivable to manually input the key corresponding to ``1 kuchi'' in katakana by using a kana shift. That is, by inputting the kana shift J, rAJ of ``口'', it becomes possible to output ``prison''.

[Effects of the Invention] As detailed above, according to the present invention, special character codes can be expressed while matching display and print columns with memory size, and it is not necessary to register all character patterns to be used. Therefore, it is possible to provide a special character representation method that dramatically facilitates the input of composite characters that are difficult to use.
