DETAILED DESCRIPTION OF THE INVENTION [Outline] A character processing device capable of inputting Japanese and having a function of storing a character string in a field formed by ruled lines when the character string is input into the field. Regarding a character processing device, vertical (horizontal) formed by ruled lines in a horizontal (vertical) written document
The purpose is to provide a character processing device that automatically converts character codes for vertical (horizontal) writing even when characters are stored in a field that stores 1 × n long characters. And a field shape recognition unit for recognizing that the field has a shape of one character in the horizontal (vertical) direction and n characters in the vertical (horizontal) direction when a horizontal (vertical) written document is created. A character code conversion unit that converts a character input into the ruled line by the identification output by the unit into a character for vertical (horizontal) writing using a conversion table is configured.

[Field of Industrial Application] The present invention is a character processing device capable of inputting Japanese and has a function of storing a character string in a field formed by ruled lines when the character string is input into the field. It relates to a character processing device.

In recent years, word processors, workstations, and the like have been widely used as character processing devices capable of inputting Japanese, and there is an enormous need for sophisticated functions. In particular, there is an increasing need for a word processor that can incorporate not only simple sentences but also tables and graphs into documents, and it is desired that the functions be further enhanced.

Among them, a function of describing various tables and describing respective attributes of a large number of items is frequently used by providing areas separated by ruled lines in the text. When you enter characters in the area surrounded by ruled lines, the characters are stored in the area of the ruled lines as a conventional Japanese processing function. However, you can write one column of characters vertically in a horizontal writing document, or in a vertical writing document. When writing one line of characters horizontally, there are cases where the characters used (including symbols) are unsuitable for vertical writing or horizontal writing, and it is desired to improve this.

[Prior Art] FIG. 6 is an explanatory diagram of a conventional example.

FIG. 6A. Is a structural diagram of a conventional example, B. Shows the operation procedure of the conventional example.

A. In the figure, 60 is a key input unit including character keys such as kana characters, alphanumeric characters and symbols, line figure input keys such as ruled line characters, control function keys such as kana-kanji conversion keys, and 61 is a key input from the key input part 60. A Japanese conversion control unit that performs processing such as Kana-Kanji conversion, 62 is a field recognition unit that identifies a field surrounded by ruled lines, 63 is a reorganization control unit that reorganizes the characters input in the ruled line field,
A character storage unit 64 stores document data including characters and ruled lines.

The characters produced as a result of Japanese conversion by operating the key input unit 60 are stored in the character storage unit 64 according to the storage direction of the document being created. In particular, when a ruled line character is input and the character forms a closed area, and when a character is input with the cursor inside the character, reorganization is performed so as to enter the area. This is shown in FIG. It will be described using the operation procedure of the conventional example shown in FIG.

This example shows a case where the field surrounded by the ruled line has a shape in which one horizontal line of characters is accommodated vertically in the horizontal writing document, and one horizontal line of characters is written in the vertical writing document. The same applies to the case.

B. In the horizontal document with ruled lines, "item 1",
A vertical field 6 that allows you to write one character in the horizontal direction and multiple characters in the vertical direction after entering characters such as "Item 2"
5 shows a state in which the cursor is placed at the head of 5.

When the character "data" is input in the state of, the field recognition unit 62 causes the field 6 where the cursor is placed.
It recognizes that 5 is surrounded by ruled lines and supplies the recognition result to the reorganization control unit 63. Reorganization control unit 63
As a result, the originally horizontally written character string "data" is reorganized in the field 65 and stored in the character storage unit 64 and displayed as shown in.

Looking at this display, if the operator judges that the character (symbol) "-" in the word "data" is inappropriate for vertical writing, move the cursor to the position "-" as shown in. Move to. Then replace that letter If you enter the character code from the key input unit 60,
The correct code is input as vertical text as shown in.

[Problems to be Solved by the Invention] As described above, in the conventional Japanese input device, when vertical writing or horizontal writing is first designated when creating a document, the character code suitable for that is automatically selected. , Vertical fields formed by ruled lines in a horizontal document (1
A character code for horizontal writing is input even when a character is input to (× n characters), and in order to change this to a character code for vertical writing, it is necessary to perform a character input operation from the key input unit. was there. Similarly, when a horizontally long field formed by ruled lines in a vertically written document has a shape in which n characters (1 × n characters) are written in one line in the horizontal direction, the same problem occurs.

According to the present invention, even if a character is stored in a field that stores vertical (horizontal) long 1 × n characters formed by ruled lines in a horizontal (vertical) writing document, it is automatically written for vertical (horizontal) writing. An object is to provide a character processing device that is converted into a character code.

[Means for Solving the Problems] FIG. 1 is a basic configuration diagram of the present invention.

Reference numeral 10 is a field shape recognition unit, 11 is a character code conversion unit, 12 is a conversion table, and 13 is a character storage unit.

The field shape recognition unit 10 and the character code conversion unit are means provided in an information processing apparatus such as a conventional word processor having a Japanese input function. The conversion table 12 stores, for character codes in which different characters are used for vertical writing and horizontal writing, a vertical writing code and a horizontal writing code in association with each other.

According to the present invention, when a Japanese character is input, the field shape is identified and a field formed by a ruled line extending in a direction perpendicular to this is stored in a vertical (horizontal) written document with a character width of n characters. When it is identified that the shape is the same, the character code conversion unit selects a character code suitable for the shape of the field and performs conversion.

[Operation] It is assumed that the input character is stored in the field formed by the ruled line character in the character storage unit 13 by the same function as that of the conventional word processor. When a character is input in the field designated by the cursor, the field shape recognition unit 10 included in the information processing device determines that the field formed by the ruled line based on the data in the character storage unit 13 is as follows. Identify which is. That is, when creating a horizontal (vertical) writing document, it is identified whether or not the shape is one character in the horizontal (vertical) direction and n characters in the vertical (horizontal) direction (this is referred to as 1 × n character shape). To do.

If the field shape recognition unit 10 recognizes that the shape is 1 × n, the character code conversion unit 11 is activated. The character code conversion unit 11 refers to the conversion table 12 for the character in the recognized field. In this case, if a horizontal writing document is being created, each character in the field (horizontal writing code) is compared with the horizontal writing code in the conversion table 12, and if they match, the vertical writing code of that code is compared. Is extracted from the conversion table and stored in the character storage unit 13 at the position where the original code for horizontal writing was stored.

1 created by horizontal ruled lines during vertical writing
Even when a field of × n characters is recognized, the character code conversion unit 11 similarly converts the character code using the conversion table.

However, in this case, the vertical writing code is converted to the horizontal writing code.

[Embodiment] FIGS. 2 (a) and 2 (b) are configuration diagrams of an embodiment of the present invention, and FIG. 3 (a) is a processing flow chart of an embodiment of a field shape recognition unit, and FIG.
(b) is an explanatory view of the principle of field shape recognition and data, FIG. 4 is a processing flow chart of the embodiment of the character code conversion unit, and FIG.
The figure is a diagram showing a specific operation example according to the present invention.

In FIG. 2A, 20 is a key input unit, 21 is a Japanese conversion control unit, 22 is a field recognition unit, 23 is a reorganization control unit, 24 is a field shape recognition unit, 25 is a character code conversion unit, Reference numeral 26 is a conversion table, and 27 is a character storage unit.

As shown in (b) of FIG. 2, the conversion table 26 shows each code of “(”, “:”, “−” ... As a code, "⌒", "...", Each code of ... Is stored.

In the structure of the embodiment, each part of 20 to 23 is the same as the structure of the conventional example (see FIG. 6), and the structure provided by the present invention is the part of 24 to 26.

The field shape recognizing unit 24 identifies the field surrounded by the ruled line by the field recognizing unit 22, and according to the result, the reorganization controlling unit 23 controls the arrangement of the character string in the field and then activates.

A processing flow of the embodiment of the field shape recognition unit shown in FIG. 3 (a) will be described with reference to FIG. 3 (b).

First, the storage state of the character data in the character storage unit (FIG. 27) will be described. As shown in, one word is stored at each address of the memory that constitutes the character storage unit, each represents one character of the JIS code, one line of data is sequentially stored, and then the data of the next line is stored. ing. This character code also includes a code representing a ruled line. In addition, c. Indicates the control data, and the width (number of characters) of one line of the current document data in this information processing apparatus and the direction flag D (for example, vertical direction) indicating whether the current document being created is vertical writing or horizontal writing. "1" for the direction and "0" for the lateral direction) are set as control data.

Also, the current cursor position (tip position in the field)
Recognizes a field of "1 × n" in the vertical writing direction in a horizontal writing document, assuming that it is the b digit of line a in FIG. 3 (a).
The process of starts.

In step 30, the recognition flag R is set to the “not 1 × n row” state (“0”). Next, at step 31, the number of rows a at the cursor position is set in the register holding the variable c. Then the number of characters (the number of characters in the field,
1 is subtracted from the value sent from the Japanese conversion control unit 21) (step 32). Next, it is determined whether the number of characters is 0 (step 33). If the number of characters is not 0, then it is determined whether the character on the right side b + 1 of the same line c is a ruled line, as shown in FIG. 3 (b).
B. The contents of the memory shown in are read out and discriminated (step 34). If it is a ruled line, 1 is added to the value of the variable c (step 35).

This moves to the next row (lower side), where b-
Similarly, it is determined whether the character of the first digit is a ruled line by reading the corresponding word in the memory (step 36). If this character is a ruled line, the process returns to the next step 32, and when the number of characters is 0 at the end by following the same flow as above, the recognition flag R is set to the state of “1 × n lines” ( Step 37).

The determinations in steps 32 to 36 are a. In FIG. 3 (b). It is performed according to the principle shown in, and before and after the b digit of the c line (b-1 and b + 1).
When the character code of is a ruled line, the same determination is made for the next line c + 1, and if it is a ruled line, it is determined whether or not the condition is satisfied for n characters (the number of input characters). Be seen. It is obvious that a 1 × n field shape in the horizontal direction in a vertically written document can be recognized by the same principle.

If NO is determined in steps 34 and 36, it is determined that the field shape is not “1 × n rows”, and the processing of the character code conversion unit 25 is not performed.

Next, the processing flow of the embodiment of the character code conversion unit will be described with reference to FIG.

When the field shape recognition unit 24 recognizes “1 × n” and the recognition flag R is set to “1”, the processing of the character code conversion unit starts, and it is first determined whether the document is a vertically written document. (Step 40). This judgment is shown in FIG.
C of (b). This can be understood by examining the direction flag D which is the control data shown in. If it is a horizontal writing document, the determination result is NO, the process moves to step 42, the search pointer is set to the head of the table (conversion table), and the data pointer is set to the table head + 1.

The conversion table is composed of a memory, and an example of the arrangement of character codes is shown in FIG. As shown in the figure, the code for the horizontal writing character "(" is stored in the first address of the table, and the vertical writing character "⌒" corresponding to the next address is stored to form one unit. A plurality of units are sequentially stored as a pair of a character and a code for a character for vertical writing corresponding to the character, and the end code ends.

Therefore, in the case of a horizontally written document, the head of the horizontally written character code is used as a search pointer to read the contents of the conversion table, and in step 43 it is discriminated whether or not it is the end (termination code). The head of the conversion character (character to be converted extracted from the character storage unit 27) in the field is compared with the character read by the search pointer (step 44). If they match, the content of the data pointer (vertical writing character in this case) is extracted and stored in the position of the converted character (character storage unit 27 in FIG. 2). If they do not match, the search pointer and the data pointer are incremented by +2 and the same processing is performed for the next character unit of the conversion table (step 48). When the conversion for one character is completed in step 45, or when the search pointer reaches the end position in step 43, the next converted character is taken out (step 46). If it is not the end of the converted character, the process returns to the first step 40. Perform the same processing as above,
When the processing is completed for all the characters to be converted, the character code conversion processing is ended (step 47).

When it is determined in the first step 40 that the document is a vertical writing document, in step 41 the search pointer is set to the table head + 1, the data pointer is set to the table head, and the address opposite to that in step 42 is set. Is set. The subsequent processing is the same as in the case of the horizontal writing document.

FIG. 5 showing a specific operation example according to the present invention will be described.

At, a table is created by ruled lines.

Moves the cursor to the beginning of the field of vertical 1 digit x horizontal n rows.

At, the Japanese sentence “(data)” is stored (not displayed) in the character storage unit in the form of entering the field by the conventional field recognition and reorganization functions.

After the input of, the shape of the ruled line field is recognized, the contents of the conversion table are checked for each character code, and the ones that match are converted.

The data after the character code conversion is displayed in the ruled line field, and it can be seen that the characters for vertical writing were correctly converted.

EFFECTS OF THE INVENTION According to the present invention, when inputting Japanese in a region surrounded by ruled lines such as a table, a document with an accurate character expression is created without requiring the user to perform a troublesome operation. You can
