2. Description of the Related Art A full-screen text editor or word processor causes a logical line separated by a line feed symbol in document data to cause a digit break for each specified number of display lines when the logical line is longer than the width of the display area. It is supposed to be displayed. In addition, in a European word processor or the like, when a word is divided by a display line, it generally has a word wrap function of sending this word to the next line. As a text processing device having such a word wrap function, Japanese Patent Publication No. 60-37944
The publication describes a text processing device that automatically moves the word at the end of one line of text beyond the right margin to the beginning of the next line of text. Also, in a text editor or word processor,
There is a device in which a plurality of document data can be simultaneously displayed on the screen of a display device and correction (editing) can be performed.

Further, Japanese Patent Laid-Open No. 63-291158 discloses a Japanese editing device for editing a translated sentence in phrase units based on information at the time of translation.

Some machine translation devices can insert translated words, phrases or sentences into the original sentence and output the original sentence. For example, in Japanese Patent Laid-Open No. 1-169672, the layout of the entire document is confirmed by designating a range to be translated and replacing the designated document with the translated document or inserting the translated sentence in the document. A document processing device capable of performing the above is disclosed. In addition, JP-A-4-21
Japanese Patent Publication No. 173 describes a machine translation device that displays words and phrases in natural language B in the form of bilingual or partial translations in the original sentence in natural language A only for words and phrases having a frequency of occurrence lower than a certain level. ing. Furthermore, JP-A-6-32
Japanese Patent No. 5081 describes a translation support device that arranges and outputs a translated word near each language in an original sentence to clarify the relationship between the language and the translated word.

[0005]

However, when a plurality of document data are simultaneously displayed and modified by a conventional text editor or word processor, each document data is divided into screens or lines or columns separated by windows. It is only displayed in each continuous display area. Therefore, it is still not enough when, for example, in the translation work, the original sentence and the translated sentence are compared word-by-word or phrase by word. There was a problem that it could not be said to be useful.

Further, in the conventional machine translation device, the original sentence and the translated sentence can be displayed or printed for easy comparison by adjoining them in word units or line units. There was a problem that it could not be corrected.

However, it is possible to create a composite document in which the original sentence and the translated sentence are mixed and thus correct the composite document. However, since such a synthesized document is treated as one independent document data different from the original sentence and the translated sentence, even if the synthesized document is corrected, the original document data and the translated sentence document data are corrected. There is a problem that the result is not reflected.

Moreover, as shown in FIG. 40, when a composite document in which an English original sentence and a Japanese translated sentence are alternately arranged line by line is corrected, for example, the position of the cursor 25 on the display screen 8a. When the Japanese character string "Japan" displayed in is deleted, the English character string "Init" displayed at the beginning of the third line is displayed at the cursor 25 position as shown in FIG. The characters are sent to the end of the second line, and the characters at the beginning of the lines are also sent to the subsequent lines, so that English and Japanese are mixed in the line and the layout is disturbed. In addition, the number of characters in one line of the composite document shown in FIG.
When the format is changed by changing the characters from 38 to 38, for example, the character string "n Japan" at the end of the first line is displayed.
As shown in FIG. 42, n ″ is sent to the beginning of the second line, and the subsequent lines also similarly have large deviations, which causes a problem that the layout is disturbed.

Further, as shown in FIG. 43, if a line feed symbol 22 is added to the end of the display line of English and Japanese sentences to create a composite document, at least English and Japanese sentences will be created unless the line feed symbol 22 is deleted. It will not be mixed in the same line. However, when processing this composite document with a European word processor that has a word wrap function,
If you change the number of characters per line from 46 to 44,
The English character string "Japan" in the line is sent to the second line word by word as shown in FIG. 44, but the corresponding Japanese character string "Japan" remains at the end of the line. As a result, the correspondence between the English words and the Japanese words or the like corresponding to the English words and the like, which is aligned and compared, is disturbed.

Even if the English words of the composite document and the corresponding Japanese words are aligned and displayed at the same position in the vertical direction as described above, the font and size of the characters are changed. There is also a problem that when printing or displaying, the correspondence may be misaligned due to the digit alignment. For example, in FIG. 45, since the English font is proportional spacing, the character width changes depending on the English character, and the correspondence with the corresponding Japanese sentence is greatly shifted toward the end of the line.

In view of the above-mentioned circumstances, the present invention provides a document processing apparatus that allows a plurality of document data to be independently corrected on a composite output, and the layout of the composite output is not disturbed by this modification or the like. Has an aim.

In the present invention (Claim 1), a RAM is suitable as the document storage means, but a hard disk device or the like can be used as long as it is a rewritable storage device. When processing the document data stored in the document storage means, a buffer provided on the RAM or the like as a work area can be used.

The line dividing means normally divides a line into a length equal to or shorter than a predetermined line division length, but when the character next to the line to be divided is a line feed symbol or a non-start of line character. , May also include these characters at the end of the divided line, and in this case, the line is divided to a length exceeding the line division length. Since this line dividing means may be executed just before the output means outputs each line, for example, the document data is divided into lines by this line dividing means and then stored in the document storage means for each line (display line). You can also Further, this line dividing means is also executed at any time after the document correcting means corrects the document data.

The output area assigned by the output area assigning unit need not be a specific position on the display screen, for example, and may be an area defined only by the relative relationship with other output areas. Also, this allocation content can be stored separately in one of the storage devices,
A program or the like for executing the output means may be held as an algorithm.

The output means selects any one of a plurality of output areas corresponding to the document data, further designates a position within the output area, and outputs each line. However, for example, in the case of allocating the output area of each document data to every other line of the display screen, in the case of a normal terminal device, it is sufficient to perform the output in order from the output area at the top of the screen and to perform a line feed after the output of each line. The output means outputs each line to a display device, a printing device, a storage device, or the like.

The correction instruction means is executed by displaying the document data output by the output means on the display screen of the display device. However, it is not limited to the case where the output unit directly outputs to the display device, but may be the case where the composite document is displayed on the display device after being output once to the RAM or the like as the composite document. The correction instruction means indicates the correction position by displaying an index such as a cursor at any character position on the display screen. The modification position is changed, for example, by accepting an input of a cursor movement key or the like of a keyboard or a pointing device such as a pen, a mouse or a tablet, and the modification content is also accepted by accepting an input of a keyboard or the like.

The document correction means selects the document data to be corrected depending on which document data is assigned to the correction position indicated by the correction instruction means, and the document data stored in the document storage means is selected. , The character position corresponding to the corrected position is corrected. The character position of the document data corresponding to the corrected position on the display screen can be detected at least by re-executing the line dividing means for the document data. Further, for example, when the previous line dividing means is executed, if a pointer indicating the character position on the document storage means of the first character of each line divided in advance is stored, the character position corresponding to the correction position is , Can be easily detected by obtaining the offset from this pointer. Further, while the correction position is relatively moved only within the output area assigned to the same document data, the pointer pointing to the character of the document data on the document storage means is made to follow the change of the correction position at any time. By moving, the corresponding character position can be detected immediately.

With the above arrangement, the output means outputs each document data to a plurality of output areas, so that a composite output can be obtained in which the relationship between the plurality of document data is more clearly compared. Further, the content of each document data can be independently corrected on the display screen by such a composite output by the document correction means. Then, when the document data is corrected by this, the line dividing unit and the output unit are executed again and the correction result is displayed on the screen, so that the layout of the combined output can be maintained. It should be noted that the line dividing means and the output means here do not necessarily have to be performed for each document data as a whole, and need only be performed for the range that is affected by the correction.

In the present invention (claim 2), the conversion processing means performs some conversion processing on one or more document data, and the new document data created by this is stored in the document storage means. Since the document data converted in this way has a special correspondence relationship with the original document data, it is possible to effectively use the above-described combined output in which the correspondence relationship is clear.

According to the present invention (claim 3),
Since the conversion processing means translates the document data of the original sentence and creates the document data of the translated sentence, it becomes more convenient by obtaining a combined output comparing these. When the document storage means is an internal storage device such as a RAM, the conversion processing means causes the new document data to be temporarily stored in an external storage device such as a hard disk device and then read and stored in the document storage means. It may be one that does.

In the present invention (claim 4), the corresponding position storage means can immediately detect the corresponding character position on the document storage means from the correction position indicated by the correction instruction means. The processing can be speeded up and simplified. The corresponding position storage means may include a storage means for storing a pointer indicating the character position on the document storage means of the first character of each divided line as exemplified above. However, for example, if a table-like corresponding position storage means that associates each row and column position on the display screen with the character position of each document data on the document storage means in a one-to-one correspondence, the search for the corresponding position can be performed more quickly. Can be done.

In the present invention (Claim 5), since the line division length of the line division can be changed, by executing the line division means and the output means based on the new line division length, an arbitrary layout can be obtained. It is possible to obtain a composite output comparing document data with.

According to the present invention (claim 6),
This line division length is set as the number of characters per line in the output format.

In the present invention (Claim 7), the unit division performed by the unit dividing means is a process for determining whether or not to set a unit division delimiter that permits line division immediately before or after each character of the document data. is there. And the line dividing means
Lines are split only at this unit division, not immediately before or after any character. Therefore, the character string delimited by the unit division is not divided in the middle of the line, so that not only the easy-to-read composite output similar to the case of performing word wrap in English sentence but also the correspondence between document data can be obtained. It is possible to prevent the relationship from becoming unclear.

In the present invention (claim 8), since each word is unit-divided, this word is not divided halfway by a line.

According to the present invention (claim 9),
Since the unit division is performed based on a delimiter such as a space character, a character string such as a word formed only of characters other than the delimiter is not divided halfway by a line. Moreover, in this case, by positively inserting an appropriate delimiter such as a space character, it is possible to clearly separate a character string having a correspondence relationship between document data from other character strings in the same document data. , It becomes possible to more reliably compare the correspondence relationships of these character strings.

Further, in the present invention (claim 10), since the unit division is carried out based on the character attribute to which an underline or other decoration is added, a character string consisting of only characters having a common character attribute is inserted in a line in the middle. It will not be divided. Moreover, in this case, by designating or changing the character attribute, it is possible to perform arbitrary unit division according to the operator's intention. The unit dividing means may be executed collectively before executing the line dividing means, or the line dividing may be performed while word-by-word division is performed simultaneously with the line dividing means.

In the present invention (Claim 11), the unit dividing means does not divide each document data into independent units, but when the unit division is performed for any document data, the same character position is used. Performs unit division of other document data. Therefore, when using a plurality of document data arranged such that the positions of the corresponding character strings from the beginning of the sentence are always the same, if any of the document data can be reliably unit-divided, Even if it is impossible to perform the same unit division on document data by itself,
Since it is possible to perform unit division in which the unit division is the same for all document data, it is possible to clarify the correspondence relationship in composite output. In this case, for other document data, without actually performing unit division,
It is also possible to simply copy or refer to the processing result of the document data that has already been divided into units.

In the present invention (claim 12), the line dividing means not only divides the line by the division of the unit division, but also makes the number of divisions by the unit division the same in the corresponding lines of each document data. Split the line into. Therefore, for example, when a plurality of character strings (division unit) of each document data are separated by a delimiter, it is possible to match the number of character strings included in the corresponding line when these document data are divided into lines. , It is possible to prevent the correspondence in the combined output from being disturbed by this line division.

According to the present invention (claim 13), the output positions of the respective division units within the corresponding lines of the respective document data can be aligned with each other. Therefore, even if the character position of the corresponding division unit differs between the document data, or the character font and size etc. at the time of display output or print output differ between the document data, the correspondence relationship in the composite output will be the same digit position. Can be reliably represented by contrasting with. Each line divided by the line dividing means for each document data is temporarily stored in the RAM.
It may be each line of the composite document output to, for example.

It is a figure which shows the synthetic output displayed on FIG.

In the present invention, a plurality of types of document data can be output in any format, but in the present embodiment, two types of document data are written as one in order to simplify the explanation.
The case of outputting every line will be described.

As shown in FIG. 2, the hardware of the document processing apparatus of this embodiment is constituted by a computer device having a CPU 1. A ROM 3 and a RAM 4 are connected to the CPU 1 via a bus 2. Bus 2
Are a large number of input / output lines including an address bus, a data bus, and the like. The ROM 3 is a read-only nonvolatile semiconductor memory device (ROM that stores programs and fixed data).
[Read Only Memory]), and the RAM 4 is a readable / writable volatile semiconductor memory device (RAM [Random Access Memory]) that stores programs and data. CPU
Reference numeral 1 denotes a central processing unit (CPU) that controls the entire apparatus by executing the programs stored in the ROM 3 or the RAM 4.
Further, in the RAM 4, a document data area for storing the document data processed by the program executed by the CPU 1 is secured, and variables such as pointers and buffers or tables used when the program processes the document data. A work area to be allocated to etc. is secured. In addition,
The document data area and the work area do not have to be continuous areas in the RAM 4, and may be a plurality of distributed areas. The document data is data having character data composed of a sequence of character codes, and with attribute data, format information, etc. added as necessary. The attribute data is
It is data that specifies fonts, character sizes, decorations such as underlines for each character code, and is specified for each character code or by delimiting the range of this character code. The format information is data that specifies an output format and the like.

The bus 2 has a VRAM 5 and a CGROM.
6 is connected, and the display device 8 is connected via the display controller 7. The display device 8 is a bitmap type display device such as a liquid crystal display device or a CRT display. In addition, the VRAM 5 is the display device 8
Is a video RAM (VRAM [Video RAM]) having addresses corresponding to all the dots on the screen of 1 to 1, and the display pattern for one screen written therein is periodically read by the display controller 7. It is displayed on the screen of the display device 8 in real time. The CGROM 6 is a ROM which stores matrix-like dot patterns and font patterns such as outline fonts corresponding to respective character codes such as characters and symbols that can be used in this apparatus. And
A character generator (CG [Character G
enerator]) refers to the font pattern of the CGROM 6 to develop the character code into a character pattern (dot-structured pattern) and write it in the VRAM 5. In the case of the outline font, this character generator develops a character pattern of an arbitrary size according to the attribute data attached to the character code. Also,
In the case of a dot pattern as well, the basic dot configuration is fixed, but it is possible to expand to a character pattern of any size by appropriately enlarging or reducing. Furthermore, depending on the type of font pattern, the width of the character pattern may differ from character to character even if they have the same size due to proportional spacing. However, in the case of displaying on the display device 8 in the present embodiment, in order to simplify the explanation, it is assumed that only the character patterns of two types of dot configurations are developed according to the type of the character code.
That is, an alphabetic code that represents alphanumeric characters and symbols in European languages is expanded into a character pattern for one character with a predetermined dot configuration,
A kanji code representing Japanese kanji, hiragana, katakana, etc. is developed into a character pattern having a size of two characters in which two alphabetic character patterns are arranged in the digit direction.
Therefore, in this case, as the VRAM 5, the video RA
It is also possible to use a text VRAM in which the character code is directly stored in M.

Further, as an input device on the bus 2,
A keyboard 10 via a keyboard controller 9 and a pen 12 via a pen controller 11 are connected, and a floppy disk drive device 14 via an FD controller 13 and a hard disk drive device 16 via an HD controller 15 as input / output devices. Further, a printer 18 via a printer controller 17 and a buzzer 20 via a buzzer controller 19 are connected as output devices. Keyboard 10
Is an input device for inputting a character or symbol or a control symbol such as cursor movement as a key code by pressing a key, and is controlled by the keyboard controller 9 to perform this input processing. Therefore, the operator can input the document data to be stored in the RAM 4 from the keyboard 10 and can also instruct the document data displayed on the display device 8 to be corrected. The pen 12 is an input device for inputting coordinates on the display screen by bringing the stylus-shaped tip close to or pressing the screen of the display device 8, and is controlled by the pen controller 11 to perform this input processing. The pen 12 can be used to indicate a correction position when correcting the document data displayed on the display device 8.

The floppy disk drive device 14 is
The hard disk drive device 16 is an external storage device that is controlled by the FD controller 13 and performs input / output with a floppy disk inserted in the device. It is an external storage device for outputting. Then, the document data stored in the RAM 4 can be written to and saved in the floppy disk or the hard disk, and the document data read from this can be stored in the RAM 4. The printer 18 is a printing device that is controlled by the printer controller 17 and prints document data and the like. At this time, in the document data, etc., each character code is RA
The character pattern may be expanded on M4 and then sent to the printer 18, or the character code may be sent as it is to the printer 18.
It is also possible to develop the character pattern in the printer 18 and print it. Buzzer 20
The output device is controlled by the buzzer controller 19 and emits a buzzer sound to alert the operator.

A schematic configuration of the document processing apparatus of the present embodiment using the above hardware will be described based on the block diagram of FIG. The document data is stored in the document data areas 23 and 24 which will be described later on the RAM 4 (document storage means). In the present embodiment, this document data is assumed to be the first and second types of document data. Here, the second document data is
The first document data (original text) stored in advance in the RAM 4 may be translated by the translation processing 31 (conversion processing means) and stored in the RAM 4 as a translated text. The first and second document data are output to the display device 8 and the printer 18 as a composite output by the output processing 32 (output means, output area allocating means). Alternatively, the composite document 33 can be stored in the RAM 4 as well. In the output process 32,
These first and second lines are divided by the line division processing 34 (line division means).
The document data is divided into lines according to the line division length, and the lines of the divided document data are alternately output to form a composite output.

The output processing 32 displays the composite output on the display device 8.
In the case of outputting the correction contents, the correction processing 35 (document correction means, correction instruction means) indicates the correction position on the display device 8 by an input operation from the keyboard 10 or the pen 12, and inputs the correction content from the keyboard 10. Accept. Then, when the correction content is input, the correspondence relationship between the document data stored in the correspondence table 27 (corresponding position storage means) described in the second embodiment and the screen position of the display device 8 is referred to as necessary. Then, the correction process 35 corrects the document data on the RAM 4. The correspondence table 27 is used for the line division processing 3
It can be created in case of 4.

The line division length used in the line division processing 34 is
By the line division setting processing 36 (line division length changing means), the output format is changed (line division length setting means) on the input screen (output format setting means) displayed on the display device 8 according to the input from the keyboard 10. be able to.

The document data can be divided into units, for example, word by a unit dividing process 37 (unit dividing means). The result of this unit division is stored as a division position in the unit division table 26 described later. Then, when the output process 32 is performed, the line division process 34 refers to the division position of the unit division table 26 to perform line division by word wrap.

Composite document 33 stored in the RAM 4
Is the bitmap output process 38 described in the second embodiment.
By (output position storage means, output position adjusting means), it is possible to display on the display device 8 or print with the printer 18 in an arbitrary font and character size. At this time, the words and the like that have been unit-divided in the unit-division processing 37 are output with their digit positions aligned.

Details of the processing operation of the document processing apparatus having the above configuration will be described. In this document processing device, the CPU 1 has a ROM 3
It operates by executing the program stored in the RAM or the program read from the floppy disk drive device 14 or the hard disk drive device 16 and loaded into the RAM 4. It is also assumed that the RAM 4 has already stored two types of document data. It is assumed that the first document data among these document data is an English sentence as shown in FIG. 3, and the second document data is a Japanese sentence as shown in FIG. Here, the blank character 21 shown as a rectangle in the English sentence of FIG. 3 represents a blank that is not actually displayed or printed, and is indicated by a downward arrow in the rectangle at the end of the sentence of FIG. 3 or FIG. The line feed symbol 22 indicates a control symbol for changing the line. These are the same in the subsequent figures. These English and Japanese sentences are divided into logical lines by each line feed symbol 22.

The character data of the first and second document data can be stored in the RAM 4 in any data structure used in a usual text editor, word processor or the like. That is, for example, the character data of each document data is divided into logical lines and stored in different areas, or these logical lines are further divided into display lines which are lines on the screen when displayed on the display device 8. Then, each display row can be stored in a different area. At this time, the area of each logical line or display line is managed by a link structure, a management table, or the like. Further, the attribute data, the format information and the like are stored in the same area as the character data or in an area secured separately in association with the character data. However, in this embodiment, attribute data, format information and the like are stored in another area not shown, and the document data means only character data unless otherwise specified. Then, as shown in FIG. 5, the first and second document data are sequentially stored in the continuous first and second document data areas 23 and 24, respectively. Further, it is assumed that the alphabet code including the blank character 21 used in the English sentence of the first document data is a 1-byte code, and the Kanji code used in the Japanese sentence of the second document data is a 2-byte code. further,
The line feed symbol 22 is assumed to be a 1-byte code. Therefore,
In the first document data, a 86-byte character code from the character "R" at the beginning of the sentence to the line feed symbol 22 at the end of the sentence is stored in the first document data area 23 having continuous addresses in the RAM 4, and the second document The data is stored in the second document data area 24 in which the 84-byte character code from the character "day" at the beginning of the sentence to the line feed symbol 22 at the end of the sentence has consecutive addresses in the RAM 4. Then, the program for processing these document data stores and manages the head addresses of the respective document data areas 23 and 24 in the work area. When storing the document data in this way, the byte length of each document data is stored separately in the work area, or a special terminal symbol is added to the end of the document data stored in each of the document data areas 23 and 24. To detect the end of a sentence. In addition, the numbers attached to the respective document data areas 23 and 24 in FIG.
Indicates the number of characters in bytes from the beginning of each area.

The first and second document data are stored in the CPU 1
By the processing of the program executed by the keyboard 10
Input from the floppy disk drive device 1
4 or the hard disk drive device 16 and read and stored in the respective document data areas 23 and 24 on the RAM 4. Further, one or both of these document data is converted into the other document data or another document data by a program, and the document data area 2 is processed.
It may be stored in 3, 24. For example, the first
When translating the first document data stored in the document data area 23 to create the second document data, as shown in FIG. 7, in step (hereinafter referred to as “S”) 21, The second document data area 2 where the English sentence of the document data is translated and the translated sentence in Japanese is used as the second document data.
4 (S22). The document data converted in this way may be temporarily stored as a file in the floppy disk drive device 14 or the hard disk drive device 16 and then stored again in the document data areas 23 and 24 of the RAM 4.

In this way, each document data area 23, 2
The first and second document data stored in No. 4 are combined and output every other line by the processing of the program executed by the CPU 1. When the output destination is the display device 8, a screen display is performed, and in this case, the contents can be corrected by interactive processing. It can also be output to the printer 18 for printing, or stored in another area of the RAM 4, the floppy disk drive device 14 or the hard disk drive device 16.

The display device 8 displays the first and second document data.
The output processing for outputting the data will be described based on the flowchart of FIG. First, for initialization, the start address (sentence) of each document data area 23, 24 is set in the pointer provided for each document data (S1), and the line division length is set according to the output format (S2), and output. The position is set to the beginning of the first line (S3), and the processed document is set to the first document data (S4). The line division length sets the length of one line (display line) when outputting document data, and the actual length and the number of dots can be specified, but in this embodiment, 1-byte alphabetic characters are used. It shall be specified as the number of characters in the code.

Next, it is judged whether or not the pointer of the current processed document has reached the end of the sentence (S5), and if it is not the end of the sentence, line division processing for cutting out one line from the processed document is performed (S6). Here, the line division process is simply a process of cutting out a character string having a line division length from the character pointed by the pointer. However, when there is a line feed symbol 22 in the middle or when the end of the sentence is reached, the line feed symbol 22 that appears first or the end of the sentence is cut out. Further, since the line division length is the number of characters of the alphabet code, when a 2-byte Kanji code is cut out between bytes, the character immediately before that is cut out. Further, in the present embodiment, when the character following the character string to be cut out is the line feed symbol 22, the line feed symbol 22 is also cut out. It should be noted that in this line division processing, it is also possible to perform clipping taking into consideration the beginning of line prohibition and the end of line prohibition rule. In addition, when the line division length is specified by the length and the number of dots, this line division processing adds character widths according to the font and size of each character sequentially from the character pointed by the pointer, and the addition result is the first line division. It is also possible to perform a process of cutting out a character before the character exceeding the length up to one character. By the way, in the case where the document data is divided into display lines and stored in the RAM 4 as described above, the line division processing is executed not when outputting but when storing the document data in the RAM 4.

When the line division processing is completed, the character string of the cut line is output to the display device 8 (S7), the pointer is moved to the next character position beyond this character string (S8), and the output position is changed. It is set at the beginning of the next line (S9). If the next document data exists (S10), the processing document is set to the next document data (second document data) (S10).
11), return to S5 and repeat the above process. However, when the preceding processed document is the last document (second document data) and there is no next document, the processed document is set to the first document (first document).
Document data) (S12), and the line division length is reset according to the output format (S13).
Return to 5. However, the process of S13 has no particular meaning here.

As a result, in the processes of S5 to S13, a character string of each line is sequentially cut out from each document data and output, and this cutout is performed for all document data 1
If the order is followed, the next character string of each line is sequentially cut out from each document data and output, and this is repeated thereafter. Further, the display device 8 receives the character strings in each of these lines and combines them on every other line in order and displays them. That is, in the present embodiment, as shown in FIG. 8, the first document data is displayed on the first and third lines of the display screen 8a of the display device 8, and the second document data is displayed on the second line. Eyes and fourth
Displayed on the line. However, in this FIG. 8, since the line division length is set to 48 characters, each line has a line feed symbol 22.
The line (display line) on the display screen 8a and the logical line match. In addition, the line feed symbol 22 at the end of the third line
Is the 49th character from the beginning of the line, but since it is cut out including the line feed symbol 22 in the line division processing as described above, it is displayed at the end of the line.

When it is determined in the process of S5 that the pointer of the current processed document has reached the end of the sentence, it is stored that the process of the document data of the processed document is completed (S14), and all the document data are stored. It is judged whether or not it is finished (S1
5). If the document data still remains, S
Returning to step 9, for the document data for which processing has been completed, one line is output and the processing for other document data is repeated. When all the document data are completed, the output process is completed.

In the above output processing, it is assumed that the combined output of the first and second document data is the number of lines that can fit on one screen, and all of these document data are output. However, if the address set in the pointer in S1 is set to the address of a character in the middle of the document data, or if the process is terminated before the pointer reaches the end of the sentence in S5, only part of the document data can be output. . As the address set in the pointer in S1, for example, each time the line division processing of S6 is performed, the address of the pointer indicating the beginning of the line at that time may be stored separately. Then, when the combined output does not fit on one screen, it is possible to perform screen switching, page switching, scrolling, or the like by performing such output processing.

Although the output process of FIG. 6 is described as being output to the display device 8 here, the same process can be applied to the case of printing output to the printer 18.
Further, such a composite output is used as a composite document in the RAM 4
It is also possible to store the data in another area of the hard disk drive device 14 or the hard disk drive device 16. Moreover, once such a composite document is created, the same screen display and printout as described above can be performed by outputting the composite document in the same manner as when processing the document data of a normal single document. Is.

The display screen 8 of the display device 8 is as described above.
In the case of correcting the first and second document data synthesized and displayed in a, first, as shown in FIG. 9, the correction position is designated on the display screen 8a by the keyboard 10 or the pen 12 (S31). The correction position on the display screen 8a is designated by the cursor 25 as shown in FIG. Then, it is assumed here that the cursor 25 is moved onto the line feed symbol 22 on the first line of the screen. The position of the cursor 25 is the first document data area 2 of the first document data indicated by the address A in FIG.
It corresponds to the position of the first line feed symbol 22 in 3. Next, the correction content is input using the keyboard 10 (S3
2) It is determined whether or not this correction content is character deletion (S33). Here, for the sake of simplicity of description, it is assumed that there are only two types of correction contents, that is, character insertion when a character is input and character deletion when a delete key is pressed. However, all correction contents can be realized by a combination of these character insertion and character deletion.

If it is determined in S33 that a character has been input from the keyboard 10, the input character is inserted at the position of the document data areas 23, 24 corresponding to the corrected position (S34). That is, here, the address A in the first document data area 23 of the first document data shown in FIG.
The character code is stored in the position of, and the subsequent character codes are shifted to the right in the figure. It should be noted that each of the document data areas 23 and 24 has a sufficient margin even after the end of the sentence of the document data. Also, in S33, the keyboard 1
If it is determined that the delete key of 0 is pressed, the character on the cursor 25 indicating the correction position is deleted (S3).
5). That is, the line feed symbol 2 at the address A shown in FIG.
2 is deleted, and the characters after the next character code are shifted to the left in the drawing. In addition, in the character deletion, the character immediately before the cursor 25 may be deleted, but here, the character on the cursor 25 is deleted.

When the character insertion or character deletion is performed in S34 or S35, the output process of the corrected document data is performed (S36). This output processing may be the same processing as that shown in FIG. 6, but since such correction affects the display output only in the portion after the correction position in the corrected document data, It is also possible to re-output only that part by the same processing as when outputting part of the part. That is, in the example of FIG. 8, the display screen 8
It suffices to re-output only after the position of the cursor 25 on the first line of a and the odd-numbered lines on and after the third line according to the correction content.

As a result, when the character is inserted, the input character is added and displayed after the cursor 25 on the first line of the display screen 8a shown in FIG.
Move by a character. Then, when characters are sequentially inserted, line division is performed by the line division process of S6 in the output process shown in FIG. 6, and the divided rear line is displayed on the third line. The line previously displayed on the third line is displayed on the fifth line.

When a character is deleted, if the deleted character is a normal character, the character next to the deleted character to the line feed symbol 22 is moved leftward by one character and displayed. If there is no line feed symbol 22 in the line, the above S
By the line division process of 6, the bullets of the line two lines below are inserted in the empty space at the end of the line, and the line two lines below is moved to the left by one character as in the case where the bullet is deleted. The operation is sequentially advanced to the line with the line feed symbol 22 or the end of the sentence. However, in the example of FIG. 8, the deleted character is the line feed symbol 22 on the first line. Therefore, in this case, S
As shown in FIG. 10, by the line division processing of No. 6, the first character string of the third line, not the second line, is sent and displayed after the deleted line feed symbol 22 at the same time, and the third line is displayed. The eye will move the remaining string to the left to the beginning of the line.

Therefore, according to this embodiment, for example, the correction of the first document data does not affect the display of the even-numbered lines of the second document data. Even though they are displayed while being alternately contrasted with each other, these document data can be independently corrected, and the layout is not disturbed.

In the correction process shown in FIG. 9, the processing program can easily know the position of the line and column on the screen where the cursor 25 is located. And this cursor 2
It is possible to easily detect which document data is corrected by the line position of 5. For example, in the above example, if the cursor 25 is on an odd line, the first
It is a correction to the document data of, and if there is an even line, the second
It is a correction to the document data of. However, in order to detect which character position in the document data the line and column position of the cursor 25 is, the document data is divided into display lines and stored in the document data areas 23 and 24. It's not always easy unless you're there. For example, in the line division process of S6 shown in FIG. 6, when cutting is performed before the line division length in order to avoid cutting out between bytes of the Kanji code, or when there is an exception of the line feed symbol 22 and the line cutting process. , And the case where the number of characters in one line fluctuates greatly due to word wrapping as will be described later, and the case where the entire document data including the line feed symbol 22 is stored sequentially as in the present embodiment. When the number of characters in one line on the display screen 8a becomes unstable due to the line feed symbol 22, the offset position from the start address of the document data can be easily obtained by a simple calculation based on the position of the line and column of the cursor 25. Can not.

Therefore, when the entire document data is sequentially stored as in the present embodiment or when the document data is divided and stored for each logical line, the line is divided by the dividing process of S6. Document data area 2
If the address of the first character of the line on 3, 24 is stored in association with the number of display lines, the offset position from the first address corresponding to the line can be easily obtained based on the digit position of the cursor 25. You will be able to detect. Further, as will be described later, a corresponding table storing the corresponding document data and the data indicating the corresponding character positions on the document data areas 23 and 24 for each coordinate position of the row and the digit on the display screen 8a is provided as a work area. If set up in
The corresponding character position on the corresponding document data can be immediately searched from the line and column position of the cursor 25.
As for the correspondence between the position of the cursor 25 and the character position of the document data, the same method as that used in a conventional ordinary text editor or word processor can be arbitrarily used.

In the document processing apparatus of this embodiment, the line division length can be changed by setting the output format. To set the output format, as shown in FIG. 11, first, the input screen of the output format is displayed on the display device 8 by operating the keys of the keyboard 10 or the like (S4).
1). On this input screen, as shown in FIG. 12, the current set values of the number of characters per line and the number of lines per page are displayed, and these values can be changed. So 1
When a new value for the number of line characters is input (S42) and the setting process is completed, the set value for the number of line characters is updated and stored (S43). For example, in FIG. 12, the keyboard 1
When the input of the number of characters per line is specified by the operation of 0 (the specified numerical value is underlined), the number of characters per line is changed from "48" to "28" by the numerical value input, and the setting process ends. 28 new characters per line in output format
It is set as a character. This output format is stored as management information by the document processing apparatus of this embodiment such as a translation program. However, it can be attached to each document data as format information of each document data. Further, although only the process of setting the number of characters in one line has been described above, the number of lines in one page can be similarly set. Then, here, the number of lines per page is changed from "6" to, for example, "1".
It shall be changed to 0 ".

When the setting of the number of characters per line and the number of lines per page is completed in this way, the same document data output processing as shown in FIG. 6 is performed based on this output format (S44). In this output process, in S2, the line division length is set to the value of the number of characters per line in the output format.
Therefore, in the case of the above example, in the line division processing of S6, the first and second document data are sequentially line divided based on the newly set line division length of 28 characters, and the display output shown in FIG. 13 is obtained. . For example, the combined output as shown in FIG. 8 is set as one combined document, and a word processor or the like outputs 1 to the combined document.
When the process of changing the number of characters in a line is performed, the layout of the correspondence between the first and second document data for each line is disturbed. However, in the document processing apparatus of this embodiment, the output format is changed. If you do, you can save this layout.

By the way, the display screen 8 shown in FIG.
In a, the word “in” in the first document data is divided into the line end of the first line and the line start of the third line, and the word “step” in the second document data is also divided into the line end of the sixth line and the line end. Since it is divided into the beginning of the 8th line, the display is hard to see.
Therefore, the document processing apparatus according to the present exemplary embodiment has a word wrap function that prevents word division. Such a word wrap function can also be realized by adjusting the division position while detecting a word at any time in the line division processing of S6 in the output processing shown in FIG. 6, but in the present embodiment. Unit division processing is performed in advance as preprocessing for necessary document data. In the unit division processing, in the case of an English sentence, it is possible to automatically divide each word by detecting the presence or absence of the blank character 21 or the like. However, instead of such uniform division, the operator may want to specify an arbitrary range as a division unit. In the case of Japanese sentences, for example, the floppy disk drive device 14 or the hard disk drive device 1
It is possible to automatically divide each word by preparing a dictionary in which the grammatical information such as the part of speech of a word is stored in 6, and performing a grammar analysis while referring to this dictionary. However, in such a method, the processing is extremely complicated and a large amount of dictionary data is required. Therefore, in this embodiment, the operator can add an underline to an arbitrary character or character string in the document data by an input operation, and the underline can specify a unit such as a word to be divided into units. I have to. The underline is attached to this document data as attribute data for each character or character range of the document data. Further, in the document processing apparatus of the present embodiment, when this unit division processing is performed, as shown in FIG. 14 and the like, each character on the document data areas 23 and 24 of the document data to be processed corresponds one-to-one. Unit division table 26 having a storage area
Are created in the work area. In each storage area of the unit division table 26, division positions for indicating word boundaries and the like are set. However, this storage area only needs to know whether or not the division position is set.
It may be a set of flags by bit fields or the like.

An example of the unit division processing for performing the unit division based on the blank character 21 will be described with reference to FIG. First, the start address of the document data to be processed is set in the pointer (S51), and then it is determined whether the character pointed to by the pointer is a blank symbol (S52). The blank symbol mentioned here is not limited to the blank character 21, but also includes symbols such as periods and commas for delimiting English words and control symbols such as the line feed symbol 22 and tabs. If the character pointed to by the pointer is a blank symbol, the division position is set in the storage area on the unit division table 26 corresponding to this character (S53).
Then, the pointer is moved by one character (S54), and it is determined whether or not the end of the sentence has been reached (S55). If the end of the sentence has not been reached, the process returns to S52 and repeats this processing. Also, S5
When it is determined in 2 that it is not a blank symbol, the process proceeds to S54 without setting the division position. When the processing is completed for all the characters of the document data in this way, it is determined in S55 that the end of the sentence has been reached, and the unit division processing ends.

When the first document data in English is processed by the above unit division processing, as shown in FIG. 14, it corresponds to the blank character 21, the period and the line feed symbol 22 on each document data area 23, 24 of this document data. The division position indicated by the upward arrow is set in each storage area on the unit division table 26. Then, here, the line division is possible only when the characters for which these division positions are set are the end of the line.

The position of the storage area on the unit division table 26 corresponding to the character pointed by the pointer can be easily calculated from the difference (offset) between the start address of the document data and the address of the pointer. . Therefore, in the unit division processing, the offset from the start address may be stored in a variable and counted without using the pointer. Further, with respect to the unit division table 26, another pointer for counting at the same time as this pointer can be used. This is also the case with other unit division processing described below.

An example of a unit division process for dividing the second document data into units based on underlining will be described with reference to FIG. In this second document data, the word “step” in the second document data area 24 is underlined in advance, as shown in FIG. However, it is assumed that this underline is actually recorded in the attribute data stored in another area on the RAM 4. First, the start address of the document data to be processed is set in the pointer (S61), the underline flag provided in the work area is reset (S62), and it is determined whether or not the character pointed to by the pointer is underlined ( S63). If the character pointed to by the pointer is not underlined, it is determined whether the underline flag is set (S64). If the underline flag is not set, the character currently pointed to by the pointer is supported. The division position is set in the storage area on the unit division table 26 (S65). And the pointer is 1
The character is moved (S66), and it is determined whether the end of the sentence has been reached (S67). If the end of the sentence has not been reached, the process returns to S63 and this process is repeated.

Therefore, in this unit division processing, as shown in FIG. 17, the division positions indicated by the upward arrows are set in the respective storage areas on the unit division table 26 corresponding to all the characters not underlined. It That is, here
Japanese sentences not underlined can be divided into lines at any character position. In FIG. 17, since the Kanji code of the Japanese sentence is a 2-byte code, the division position is set only in each storage area on the unit division table 26 corresponding to the first byte.

When it is determined in S63 that the character pointed by the pointer is underlined, the underline flag is set (S68), and the process proceeds to S66. Therefore, since the dividing position is not set in principle for the underlined character, it is not possible to perform line division with this character as the end of the line. When processing the first character that is not underlined after processing the underlined character, it is determined that the underline flag is set in S64, so this underline flag is reset. At the same time (S69), the division position is set to the character one character before the character currently pointed to by the pointer (S70), and the process proceeds to S65. Therefore, here, the division position is also set to the last character of the underlined character string. That is, in the example of FIG. 17, the division position is also set to the last character “p” of the underlined word “step”. This is to enable line splitting at the position when the underlined word is the end of the line.

When the document data subjected to the unit division processing is to be output, the line division processing of S6 shown in FIG. 6 has the processing contents shown in FIG. That is, first, when the character pointed by the pointer used in the output processing is the number of characters of the line division length ahead, or the first line feed symbol 22 appearing in the middle or the end of the sentence is reached, the number of characters up to the end of this sentence is used as the variable of the character string length. Is temporarily set (S81). Next, it is determined whether or not the division position is set to the character ahead of this character string length from the pointer (S82). Further, here, it is assumed that the division position is set even when the character preceding the character string length is the end of the sentence. Then, when the division position is set, the processing is ended as it is. In the output processing shown in FIG. 6, the line output in S7 and the pointer movement in S8 can be performed using this character string length. However, if it is determined in S82 that the division position is not set in the previous character by the character string length, the number of characters of this character string length is reduced by one character (S83) and the process returns to S82.
The length of the character string to be cut out by line division is shortened until a character whose division position is set appears. Incidentally, in an actual program, it is necessary to separately provide a measure for the case where the character string length is 0 character.

As a result, for the first document data,
Line breaks are performed only at the positions of the English blank character 21, period, or line feed symbol 22. For the second document data,
Since line division is not performed in the middle of the underlined character string, the word “in” divided in the first and third lines in FIG. 13 is changed as shown in FIG. The word "step" displayed at the beginning of the third line and divided into the sixth line and the eighth line in FIG. 13 is also underlined so that the word "step" is displayed in the eighth line as shown in FIG. Will be displayed at the beginning of the line, and the word wrap function can make the synthesized document easier to see.

Incidentally, in the unit division processing shown in FIG.
In the division position setting processing of S65, if the division position is changed only when it is an English blank symbol or a Japanese sentence character (kanji code character), the English sentence and the Japanese sentence are distinguished from each other. The same unit division process as described above can be performed in common. Further, in this case, it is also possible to underline the English sentence and suppress line division between the underlined character strings.

Further, with respect to the English sentence, not only the word wrapping described above but also hyphenation can be performed to divide a word related to line division by adding a hyphen. The word division position by such hyphenation is determined by referring to a dictionary stored in the hard disk drive device 16 or the floppy disk drive device 14.

FIG. 9 is a diagram showing another output image by the bitmap output process. The same members as those shown in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The hardware configuration of the document processing apparatus of this embodiment is the same as that of the first embodiment shown in FIG. In addition, in the present embodiment, a case will be described in which the first document data in English is translated into Japanese by the translation process shown in FIG. 7 and is created as second document data. However, the second document data here is an array of Japanese words and the like corresponding to each English word in the first document data. Then, the corresponding English word and Japanese word, etc. are appropriately blank characters 21 so that the digits of the leading characters of them are aligned with each other.
Is inserted. Therefore, the translation process here is a conversion process of first translating the first document data to create the second document data, and also inserting the blank character 21 for aligning the first document data. The contents are rewritten by applying. Such rewriting of the contents of the document data is performed, for example, by converting the first document data to create the third document data, and discarding the original first document data to replace the third document data with the first document data. The document data may be changed to 1.

It is assumed that the first and second document data are sequentially stored in the respective document data areas 23 and 24 of the RAM 4 as in the case of the first embodiment. However, since the blank character 21 for digit alignment is inserted in both sides, the corresponding word or the like is stored at the same offset position from the start address of each document data. For example, the English word "started" and the corresponding Japanese phrase "Started" are both stored after the 21st character from the beginning of the sentence. Further, it is assumed that both document data are each composed of only one logical line, and the line feed symbol 22 is added only at the end of the sentence.

The document processing apparatus of this embodiment also outputs the document data by the same output processing as that shown in FIG. In this case, in the line division process of S6 in the output process of FIG. 6, assuming that the number of characters per line of the output format is set to 46 characters, each output line is cut out and line division is performed as shown in FIG. Become. At the time of this cutout, it is also possible to actually prepare a buffer for 46 characters as shown in FIG. 21 in the work area of the RAM 4 and once copy it. Then, as shown in FIG. 22, on the display screen 8a of the display device 8, the first and second document data are alternately output every other line, and the Japanese corresponding to the English words in each odd line are displayed. The digits are aligned and displayed on each even line under the line. However, for the sake of simplicity, here, a case is shown in which the end-of-line character of each divided line is a period or a blank character 21, and even if line division processing by unit division is performed, as shown in the first embodiment. No word wrap will occur.

The correspondence between the character positions on the document data areas 23 and 24 of the document data and the row and column positions on the display screen 8a when the above display output is performed will be described with reference to FIG. For example, the first character "b" of the word "broadcasting" in the first document data area 23 of the first document data is displayed on the first screen of the display screen 8a through line division as shown by arrows B and C in the figure. Corresponds to the 8th digit of the line. In addition, the first character "day" of the word "Japan" at the end of the sentence in the second document data area 24 of the second document data is displayed on the display screen 8a via line division as shown by arrows D and E in the figure. Corresponds to the 4th to 5th digits of the 6th row. Then, in the document processing apparatus according to the present embodiment, when the same correction processing as that shown in FIG. 9 is performed, the correspondence table 27 as shown in FIG. 24 is used to associate such document data with the display screen 8a. I try to manage the relationship. The correspondence table 27 is provided in the work area of the RAM 4.

The correspondence table 27 has a storage area 27a corresponding to each row and column position of the display screen 8a on a one-to-one basis. Each storage area 27a stores the number of document data and the character position. It has become. Document data number is
A number for distinguishing the first and second document data,
Here, the number "1" indicating the first document data is stored in all the storage areas 27a corresponding to the odd-numbered rows of the display screen 8a, and the second number is stored in all the storage areas 27a corresponding to the even-numbered rows. The number “2” indicating the document data is stored. The position of the character indicates the position of the character of the document data in bytes from the start address. For example, the character "b" in the first row, eighth digit of the display screen 8a illustrated above corresponds to the first row, eighth digit, storage area 27a of the correspondence table 27, and the character data of the document data stored here is stored. It can be seen from the number “1” and the character position “8” that the first document data is stored in the eighth character from the start address. In addition, the 6th line 4th to 5th of the display screen 8a
The character “day” in the digit is the fourth to the sixth in the correspondence table 27.
The fifth-digit storage areas 27a and 27a correspond to each other, and by the document data number "2" and the character positions "96" and "97" stored therein, from the start address of the second document data in byte units. It can be seen that is stored in the 96th and 97th characters. These document data numbers and character positions may be sequentially written in the storage area 27a during the line division processing of S6 in the output processing shown in FIG.

Therefore, in the program for correcting the document data in the document processing apparatus of this embodiment, when the correction position is designated by the cursor 25 on the display screen 8a in S31 shown in FIG. 9, the correspondence table 27 is displayed. By referring to, it is possible to immediately search for the document data to be corrected and the position on the document data areas 23 and 24 from the position of the line and column of the cursor 25.
It becomes possible to easily perform the character insertion of S34 and the character deletion of S35. Further, by using such a correspondence table 27, the correspondence relationship between the document data and the display screen 8a can be collectively held here, so that the composite document is created by the output processing shown in FIG. 6 and temporarily stored in the RAM 4, for example. After that, even if the output is displayed on the display device 8 and the correction is performed, if the correction for the composite document is detected, the original document data can be easily corrected based on the detected correction. However, when the document data is modified or the screen display is switched, the contents of the correspondence table 27 also need to be updated. In addition, in the case of correction of the composite document, it is necessary to recreate the composite document and the correspondence table 27 in order to reflect the correction result on the display screen 8a.

The document processing apparatus of this embodiment also has a word wrap processing function as in the case of the first embodiment. However, in the present embodiment, a unit division process different from that shown in FIG. 15 and FIG. 16 is exemplified. In the unit division processing shown in FIG. 25, first, the start address of the document data to be processed is set in the pointer (S91), the blank flag provided in the work area is set (S92), and the character pointed to by the pointer is a blank symbol. It is determined whether or not (S93). The blank symbol here has the same meaning as the blank symbol in S52 shown in FIG. If the character pointed to by the pointer is not a blank symbol, it is determined whether the blank flag is set (S94), and if the blank flag is set, the blank flag is reset (S95),
The division position is set in the storage area corresponding to the character pointed by the pointer on the unit division table 26 shown in FIG. 26 (S96). Then move the pointer by one character (S
97), it is determined whether the end of the sentence has been reached (S98), and if it is not the end of the sentence, the process returns to S93 to repeat this process. When it is determined in S94 that the blank flag is not set, the process proceeds to S97 without setting the division position. Therefore, in the example of the first document data shown in FIG. 26, the division position is set to the first character “R” of the word “Radio” at the beginning of the sentence, but each subsequent character “adi” is set.
No division position is set for o ”.

If it is determined in S93 that the character pointed to by the pointer is a blank symbol, the blank flag is set (S99) and the process immediately proceeds to S97. Therefore, in this unit division process, the division position is not set in the blank symbol. However, once the pointer passes the blank symbol, it sets the split position only to the first non-blank character. That is, in this unit division processing, as shown in FIG. 26, the division position is set only for the first character of each word delimited by the blank symbol. The reason why such a division position is set is that a blank character 21 or the like added for digit alignment after each word is attached to this word and word wrapping is performed. Therefore, line division is performed only immediately before this division position, as will be described later. In the Japanese sentence of the second document data, since one or more blank characters 21 are always added after each word, etc., this unit division processing puts the same position as in the case of the first document data. The division position can be set.

When the output processing shown in FIG. 6 is performed on the first and second document data subjected to the unit division processing of FIG. 25, the line division processing of S6 is performed by the same processing as that shown in FIG. You can also do it. However, in this embodiment, the meaning of the division position is different from that in the first embodiment, so S8
In the process shown in FIG. 2, it is necessary to judge whether the division position is set not to the character ahead of the pointer by the character string length, but to the character one character ahead. Further, in the case of inspecting the character one character ahead in this way, it is necessary to judge whether or not the end of the sentence is reached, and when the end of the sentence is reached, it is necessary to perform the same processing as when the division position is set.

Here, the operation of the line division processing according to FIG. 18 will be described in detail based on the example of FIG. For example, when the line division length is 50 characters, the first document data area 23
When attempting to divide the first document data stored in to the line, the 50th character of the character string length temporarily set in S81 becomes the first "t" of the word "Initiates". But,
Since the division position is not set in the unit division table 26 for the character "i" which is one character ahead, when the character string length is sequentially subtracted in S83, when the character string length becomes 46 characters, one character The previous character becomes "I" with the division position set. Therefore, in this line division, a character string of 46 characters is cut out, and word wrapping is executed by sending the words "Initiates" and the subsequent lines to the subsequent lines.

For example, for the first and second document data output as shown in FIG. 22, the number of characters in one line is 4
By changing from 6 characters to 44 characters and re-executing the output processing by the line division processing, a display output as shown in FIG. 28 can be obtained. In this display output, since each word and the like are integrated with the trailing blank character 21 and the like, the length of the character string cut out from the first document data by line division and the second document data in the next output line are used. The length of the character string cut out by line division always matches, and it is possible to surely hold the correspondence at the digit position between the English word and the corresponding Japanese word or the like.

By the way, in this embodiment, since the translation processing is performed such that one or more blank characters 21 are always added after each word or the like of the Japanese sentence in the second document data, FIG. The setting of the division position by the unit division process shown in is the same as that of the first document data. However, for example, as shown in FIG. 29, when the second document data stored in the second document data area 24 does not always have the blank character 21 added after each word of the Japanese sentence, etc. , The division position on the unit division table 26 for the first document data stored in the first document data area 23 is not the same. In Fig. 29, words such as "radio" and "broadcast" or "started" and "de"
Since the blank character 21 is not added between, for example, it is impossible to set the division position by distinguishing them. Therefore, in such a case, using the first document data as a reference document, unit division processing is performed only for this first document data, and the second document data has the division position set here. It can also be used as is. In the unit division processing of all the documents in this case, as shown in FIG. 30, first, the first document data is selected (S101), and it is judged whether this document data is the reference document (S102). Only when it does, unit division processing is performed (S10).
3). When the next document data exists, (S
104) and selects the next document data (S10).
5) The process returns to S102 and repeats this process, and if the next document data does not exist, the output process is performed (S106). However, the output processing here is executed by sharing the setting of the division position for the reference document with all the document data. Therefore, in the case of the example shown in FIG.
By performing the unit division process on the English sentence of the first document data and sharing the division position set in the unit division table 26 also for the Japanese sentence of the second document data, it corresponds to the English word due to the difference of the division position and this. It is possible to prevent the occurrence of disorder in the correspondence with Japanese words and the like.

Further, as shown in FIG. 30, when the unit division processing is performed only for the reference document and the division position is set, the line division processing of FIG. 18 is first executed only for this reference document, and other documents are With respect to data, it is also possible to uniformly divide the lines according to the length of the character string that is actually divided into lines in this reference document. In this case, FIG.
In the line division processing, the value of the line division length needs to be directly subtracted in S83, instead of the character string length obtained by copying the line division length. Then, by first correcting the line division length of the reference document based on the division position, other document data thereafter is uniformly divided into lines on the basis of the corrected line division length. It is possible to perform the same line division processing as in the case of sharing the division positions set in the table 26. The corrected line division length is reset according to the output format when returning to the processing of the first document data, that is, the reference document, by the processing of S13 in the output processing shown in FIG.

Further, depending on the translation process, there may be a case where one blank symbol is always added between each word or the like in the first and second document data, but two or more blank symbols are not added. In this case, the digit positions between the corresponding words in the first and second document data are not aligned, but the number of division positions set by the unit division process is the same. Therefore, when outputting such first and second document data, line division processing as shown in FIG. 31 can be performed. That is, first, when the character pointed by the pointer used in the output process reaches the previous character by the number of characters of the line division length, or the line feed symbol 22 appearing in the middle or the end of the sentence, the number of characters up to the end of this sentence is temporarily stored in the variable of the character string length. It is set (S111). next,
It is determined whether the division position is set to the character one character ahead from the character ahead of the number of characters of this character string length from the pointer (S112). Further, here, it is assumed that the division position is set even when the character preceding the character string length is the end of the sentence. If the division position is not set, the number of characters of the character string length is reduced by one character (S114), the process returns to S112, and the character is cut out by line division until the character for which the division position is set appears. Reduce column length.

When it is determined in S112 that the division position is set one character ahead, it is determined whether or not the division number of the previously processed document data matches (S114). Ends the line division processing. However,
When processing the first document data, the judgment here should always be the same. The number of divisions is the number of division positions in the line divided by the line division. If it is determined that the number of divisions does not match in S114, it is determined whether the number of divisions is larger than other document data (S115). If the number of divisions is large, S11 is determined.
Return to 3 and further shorten the length of the character string to be cut out. However, when the number of divisions is smaller than the others, the re-processing is performed again for the previously processed document data, in which the line division processing of the relevant line is redone. In order to perform this re-processing, it is necessary to cancel the line output (S7) and the pointer movement (S8) of the document data which has been subjected to the line division process for the line. However, in the document data to be subjected to the line division processing again, the line division is performed according to the small number of divisions this time, so that line division can be performed according to the document data having the minimum number of divisions.

When the first and second document data are aligned by adding one or more blank characters 21 after the word or the like, the unit division of FIG. 15 shown in the first embodiment is performed. When the process is performed and the line division process of FIG. 18 is performed, the division positions are set for all the blank symbols, and line division is possible here. Therefore, for example, a short Japanese word corresponds to a long English word. In such a case, even if a long English word is sent to a subsequent line by word wrapping, a short Japanese word or the like may be divided into lines in the middle of the trailing blank character 21 and remain on that line. For example, regarding the first and second document data in FIG.
If the number of characters in one line is changed from 46 characters to one character and changed to 45 characters, the word "Japan" at the end of the first line is sent to the third line in word wrap because the character "n" is not the split position. However, for the word "Japan" at the end of the second line, the blank character 21 immediately after that is the dividing position, and the correspondence relationship remains in the second line and is disturbed.

Therefore, even in such a case, if the line division processing as shown in FIG. 31 is performed, it is possible to obtain an output in which the correspondence relationship shown in FIG. 28 is held. However, since the unit division processing is the processing of FIG. 15 in the case of the first embodiment, in the processing of S112, the division position is not the character one character ahead, but the character itself that is ahead by the number of characters of the character string length from the pointer. Determine if it is set. Further, the number of divisions is not the number of division positions, but it is necessary to count the number of words and the like divided at the division positions. As a result, if an attempt is made to divide the line in the second document data after the word "Japan" at the end of the second line shown in FIG. 22, the number will be larger than the number of divisions in the first line for the first document data. Therefore, this word "Japan" can also be the target of word wrap.

In the unit division processing, the division position corresponding to the underline can be set by the processing shown in FIG. Here, it is assumed that each character of the document data or the character range is underlined in advance. In the example of the first document data stored in the first document data area 23 shown in FIG. 33, a plurality of related words are underlined so as not to be divided by line division. Figure 32
The processing of S121 to S129 in the unit division processing shown in (5) corresponds to S91 to S99 shown in FIG. 25, respectively. However, the relationship between setting and resetting the underline flag is
This is the reverse of the case of the blank flag, and in S123, it is determined whether or not the character pointed by the pointer is underlined. Therefore, in this unit division processing, the underlined character string is treated in the same manner as the word in the case of FIG. 25, and as a result, as shown in FIG. 33, the beginning of each underlined character string The division position can be set only in the storage area on the unit division table 26 corresponding to the character.

If the unit division processings of FIGS. 32 and 25 are combined, the division position is set only for the first character of the character string underlined or the first character of the word not underlined. You can also do it. For example, as shown in FIG. 34, if an underline is added to the character string “in Japan” of the first document data on the first line of the display screen 8a, 1 is obtained as in the case of FIG. When the number of line characters is changed from 46 to 44 and the output process is performed again, a display output as shown in FIG. 35 can be obtained. In this display output, the character string "in Japan" is word-wrapped as a unit and sent to the beginning of the third line. However, in this case, if the same unit division processing was performed for the second document data as well, this Japanese sentence is not underlined, so the character string of "de Japan" corresponding to "in Japan" Is divided, and the display output as shown in FIG. 35 is not obtained. Therefore, when performing line division processing in which the numbers of divisions match as shown in FIG. 31, the number of divisions is not the number of division positions set under the influence of an underline, but the number of words or the like separated by blank symbols. It must be counted. Further, as shown in FIG. 30, the setting of the division position for the first document data may be shared with the second document data. As a result, in FIG. 34, the character string of "in Japan" on the second line is word-wrapped together with the character string of underlined "in Japan" on the first line, as shown in FIG. As described above, since they are sent to the third and fourth lines, respectively, the correspondence between English sentences and Japanese sentences can be retained.

Further, according to the unit division processing shown in FIG. 36, it is possible to set division positions corresponding to a plurality of character decorations including underlines. In this unit division processing, first, the pointer is set to the beginning of the sentence (S131), a dummy is set to the decoration variable provided in the work area (S132), and the type of decoration of the character pointed to by the pointer is the same as the setting of the decoration variable. It is determined whether or not (S133). The dummy is a virtual decoration that is different from any kind of decoration. If the decorations are different, the division position is set (S134), and the decoration variable is set to the decoration type of the character (S135). Then, the pointer is moved by one character (S136), and it is determined whether the end of the sentence is reached (S1).
37) If it is not the end of the sentence, the process returns to S133 and this process is repeated. If it is determined in S133 that the decorations match each other, S is set without setting the division position.
Move to 136. Therefore, in this unit division processing, every time the decoration of a character is changed, including the case where there is no decoration, the division position is set to the first character.

When the composite document of the first and second document data is created by the output process of FIG. 6 and stored in the RAM 4, this composite document is displayed on the display device 8 and the printer 18 by the bitmap output process shown in FIG. Can be output to. Each character code of the composite document here is VR
After being developed into a character pattern on the AM 5 or the RAM 4, it is sent to the display device 8 or the printer 18. It is also assumed that the unit division table 26 is created for this composite document and the division positions in the first and second document data are copied to the corresponding storage areas of the unit division table 26.

In this bitmap output process, the image pointer is first set to the initial position (S141). The image pointer indicates an address on the VRAM 5 or the RAM 4, and its initial position is, for example, as shown in FIG.
The address corresponding to the upper left end point P1 in the output image shown in FIG. However, in the following description, the address value of this image pointer is represented by the corresponding position on the output image. Next, the character pointer is set to the start address of the composite document on the RAM 4 (S142), and it is determined whether the character pointed to by the character pointer is the division position (S143). If the character pointed to by the character pointer is at the division position, it is determined whether the line currently being processed is the reference line (S144). The reference line is a line in which the first document data serving as the reference document is output among the lines of the composite document, and here, the odd number line is the reference line. If the line currently being processed is the reference line, the address values of the image pointer are sequentially stored in the order of the division positions detected in the line (S145). If the line is not the reference line,
Of the address value of the image pointer, the position in the digit direction is changed so as to match the address value of the previously stored image pointer at the divided position in the same order (S146), and the character pointed by the character pointer is output (S147). ). Also,
When it is determined in S143 that the character pointed by the character pointer is not at the division position, the process immediately proceeds to S147. When the character is output in S147, the character generator reads the font from the CGROM 6 based on the attribute data of the character and develops it into a character pattern of the designated size.
Then, this character pattern is written in the address position on the VRAM 5 or RAM 4 indicated by the image pointer.

When the above character output is completed, the image pointer is moved to the right in the digit direction by the width of the character pattern in which the character is expanded (S148), and the character pointer is also moved by one character (S149). It is determined whether this character pointer has reached the end of the line (S150). When the end of the line is reached, the image pointer is moved downward in the line direction by the line feed width (S151), and the character pointer is also moved to the beginning of the next line (S152). It is determined whether the end of the sentence has been reached (S153). If it is determined that the end of the line has not been reached, the process immediately shifts to S153. This S1
If it is determined in 53 that the end of sentence has not been reached, S1
Returning to step 43, the above processing is repeated, and when it is determined that the end of the sentence has been reached, the bitmap output processing ends.

According to the above-mentioned bitmap output process, FIG.
In the output image shown in FIG. 8, first, each character from the first line, first digit in the composite document is sequentially output, and each character pattern is expanded to the rightward in order from the position of the point P1 which is the initial position of the image pointer. Written. At this time, the points P1 to P3 indicated by the image pointer when the first character of each word is output are the first to third points, respectively.
Stored as the th split position. Then, even when the processing of the first line of the composite document is completed and the respective characters from the first digit of the second line are sequentially output, the point P4 which is expanded into a character pattern and indicated by the address value of the image pointer Are written in order from the position. However, the point P4 where the character "LA", which is the first division position of this line, is written is the same digit position as the point P1, and the point P5 where the character "release" of the next division position is written is the same digit position as the point P2. Then, the point P6 where the character "S" at the third division position is written is also the same digit position as the point P3,
The position is lowered by the line feed width in each direction. When each character pattern is written in the VRAM 5 or the RAM 4 in this way, the display controller 7 reads it from the VRAM 5 or outputs the dot configuration pattern in the RAM 4 to the printer 18 to output the image shown in FIG. It is possible to obtain a display output or a printed output as usual.

In the bitmap output, the width of the character pattern differs depending on the font and size of the character, so if the number of characters in bytes from the beginning of the line is the same as described above. The digit positions on the output image are not always the same. However, according to the bitmap output process, the English word and the corresponding Japanese word or the like are aligned in the same digit position regardless of the font or character size difference between the first and second document data. Can be output. Therefore, as shown in FIG. 39, even if the font of the first document data has a different character width depending on the characters due to proportional spacing,
It becomes possible to align each digit position of each word and the like of the document data with that of each word of the first document data and output.

In the output process shown in FIG. 6 as well, by performing the same process as the bitmap output process, the bitmap is directly generated from the first and second document data without creating a composite document. It is possible to display or print out the method.

[0115]

As is apparent from the above description, according to the document processing apparatus of the present invention, each document data can be independently corrected on the display screen on which a plurality of document data are combined and output. It is possible to prevent the layout of the composite output from being disturbed by this correction or the change of the format. Further, it is possible to compare and output a plurality of document data so that the correspondence is clear.
