Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display method in a document processing device that proofreads and edits characters on the screen of a display device.

[Background of the Invention] Conventional document processing devices store multiple article data, such as proofreading and editing devices, and use C, for example, which can display kanji and graphics.
There are those that lay out articles in a predetermined format based on commands from an RT terminal and display the results on the screen of a CRT terminal, and Japanese word processors.
In some cases, an operator creates a document based on a predetermined format. If there is a part that needs to be corrected after the layout or document is created, it has a function of calling up the desired article or document on the screen of the CRT terminal device and making the corrections.

For example, in a Japanese word processor, you can move the display screen up or down to a desired location by pressing the scroll key.
Alternatively, by specifying a page, the desired page is called up and displayed, and by specifying a line, the page is scrolled to the desired line and displayed. Then, the cursor is moved to a desired location to perform corrections such as insertion, deletion, correction, etc.

For example, as shown in FIG. 2(a), the character string 40 displayed on the display screen of the display unit 19 is represented by "mouth" for purposes of explanation. ), when inserting the character string 43rABCJ between “i” and “u” in the character string [...Aiueo...],
The cursor 41 set between the lines is moved from the current position to the desired insertion point "U" as shown by the arrow, and an insertion command is input. When the insert command is input, a command 42 is displayed at the bottom of the display screen, and a character string 43r to be inserted is displayed.
When ABCJ is input, the character string 43 is displayed. In this way, once the character string 43 to be inserted has been input, the character string 43rABCJ is inserted as shown in FIG. 4(b).

[Problems with Background Art] However, in such conventional document processing devices, in order to display a desired location on the display screen, a page must be specified.

It was necessary to specify a line and then move the cursor to the desired location for corrections.

Additionally, when displaying a desired location on the display screen, the format on the manuscript may differ from the format on the display screen (on the document data), and the desired location on the manuscript may differ from what page in the document data. Since it is not easy to determine whether the desired location is located in the row, the above-mentioned designation method causes the trouble of repeatedly performing operations to display the desired location.

OBJECT OF THE INVENTION An object of the present invention is to provide a display method in a document processing device that allows a desired location to be called up quickly and accurately.

[Summary of the Invention] The present invention provides a document processing device that proofreads and edits characters on the screen of a display device; a screen configuration information section that stores information necessary for displaying document data on the screen; a calibration screen display information creation section that creates calibration screen display information based on the screen configuration information section; a calibration screen display information section that stores the calibration screen display information created by the calibration screen display information creation section; and a calibration screen display information section that stores the calibration screen display information created by the calibration screen display information creation section. a display section that displays document data based on the information section; an input buffer that stores character strings and function symbols input in the order of appearance; a search table that creates a search table based on the character strings and function symbols in the input buffer. a creation unit; a search unit that sequentially searches for character strings and function symbols in the document data based on the search table; and a search unit that sequentially searches for character strings and function symbols in the document data; memorize; create a search table based on the character string; sequentially search the document data for the character string in the search table; and rewrite the information displayed on the proofreading screen each time a matching character string is found; , is characterized in that the line containing the character string is scrolled and displayed.

In other words, as shown in FIG. 1(a), when scrolling to a desired character string t'DEJ in the document data, as shown in FIG. The character string or function symbol that appears first within a predetermined range (in the illustration, rABcJ).

"Dan") etc. to create the search table 30, rABcJ → "Dan" → rDEJ.

The search is started in order, and each time the character string is searched, the searched character string is scrolled and displayed as shown in (b). This allows rABcJ.

Only the desired character string rDEJ appearing next to "dan" is searched. Once the desired character string rDEJ is retrieved, processing such as insertion', deletion, correction, etc. is performed on the character string as necessary.

This is a search unit that searches for document data.

Next, the operation will be explained. Although the case of horizontal writing will be explained, the same can be applied to the case of vertical writing.

, (Setting of screen configuration information) Screen configuration information necessary for displaying document data on the display screen of the display unit 19 is set using the input unit 10 . The screen configuration information to be input includes, for example, the vertical/horizontal designation of the document data to be displayed on the display unit 19 (the figure shows horizontal) as shown in FIG. 4, and the character pitch (Px) indicating the space between nine characters. , line spacing (PY), which indicates the amount of free space between lines; X size (x), which indicates the size of the displayed characters in the X (horizontal) direction; Y) Origin coordinates (0) indicating the coordinates that are the display origin on one screen.

The number of characters (m) that indicates the number of characters included in one line on the screen
9 Set the number of lines (n) indicating the number of display lines on the screen.

(Calling of Document Data) A desired document name is input from the input unit 10 and the document name is stored in the document name register 12. The file control unit 14 reads the document data of the document name stored in the document name register 12 from the document file 13 and stores it in the document buffer. Store in 1.5.

The document data stored in the sentence buffer 15 is sequentially sent to the proofreading direction display information creation section 16, and the screen configuration information section 1
Calibration screen display information is created based on the information in No. 1 and stored in the calibration screen display information section 17. FIG. 5 shows the correspondence between the display screen and the calibration screen display information.

The document data in the document buffer 15 is read from the first line address A D s based on the information in the screen configuration information section 11, and the line address 17-1 .
A first character position 17-3 is created which indicates the number of characters in one line 17-2 and the total number of first characters of each line on the display screen from the first character of the first line. According to the calibration screen display information in FIG. 5(a), the display 1lIJI11 section 18 is displayed in
) The document data is displayed on the display 1 section 19 as shown in FIG.

Furthermore, when page designation 0 screen scrolling or character string scrolling 7, which will be described later, is commanded from the input unit 10, document data is sent to the proofreading screen display information creation part 16 from the desired line address according to the command, and the proofreading screen is displayed again. By creating the information, the display control unit 18 displays the scrolled document data on the display unit 19.

(Character String Scroll) Character string scroll is designated from the input unit 10 and the command is stored in the input command register 20. In order to accurately search for a desired character string or function symbol (hereinafter simply referred to as a character string) and a desired character string to be searched from the input section 10, a function symbol that appears earlier than the desired character string within a predetermined range is used. An arbitrary number of character strings are input and stored in the input buffer 27. Search table creation, section 29 is command register 2D
A search table 3o is created based on the character string (II) in the input buffer 27 by the stored character string scroll command.

As shown in FIG.
J) from the search table 30, and on the other hand, document data of the number of characters of the character string is read from the document buffer 1S and compared. When a character string to be searched is found in the document data, the comparison circuit 60 sends the line and character position of the search character string to the line register 219 and character position register 22, and the pointer control circuit 61 sends the line and character position of the search character string to the line register 219 and character position register 22.
and searches for the next character string "dan".

On the other hand, when a character string is searched and one character position of a line is written to the line register 21 and the character position register 22, the proof processing unit 28 starts the document buffer 1 from the line indicated by the line register 21.
The document data of No. 5 is sent to proofreading screen display information creation s16. Thereafter, by creating the proof screen display information as described above, the document data is scrolled and displayed on the display screen up to the searched character string. In this way, by sequentially searching the search table 30 consisting of a desired character string and character strings that appear before the character string, the desired character string is scrolled and displayed each time it is searched.

(Generation of cursor) When generating a cursor and specifying the desired position, input section 1
By instructing cursor generation from 0, the command is stored in the input command register 20.

This command sends a signal to the calibration screen position calculation section 26 and the cursor generation section 23. Upon receiving this signal, the cursor generation unit 23 generates a cursor based on the screen configuration information in the screen configuration information unit 11 and the size of the character at the position indicated by the line register 21 and the character position register 22 set in advance. The display position signal is calculated and the display position signal is sent to the display control section 18. The display control unit 18 generates a cursor corresponding to a character at the display position on the display unit 19.

Thereafter, by moving the cursor from the input unit 10 using the cursor keys, the coordinates indicating the current position of the cursor are stored in the X coordinate register 24 and the Y coordinate register 25, and the calibration screen position calculation unit 26 calculates the screen configuration of the screen configuration information unit 11. Based on the information, it is calculated which line and character the cursor position indicated by the X coordinate register 24 and Y coordinate register 25 is, and stores it in the line register 21 and character position register 22, respectively. The cursor generating section 23 calculates the display position and generates a cursor as described above.

Note that the X coordinate register 24. Y coordinate register 251 calibration screen position calculation unit 26 calculates line and character positions relative to the coordinates on the tablet (on the screen) when specifying a position on the tablet. Therefore, when moving the cursor using the cursor keys on the keyboard as described above, it is sufficient to simply output the line and character position where the cursor is located, so the X coordinate register 24. Y coordinate register 259
The calibration screen position calculation unit 26 may not be provided.

(Proofreading Process) As described above, move the cursor to a desired position and perform proofreading processes such as insertion, deletion, and correction. In the present invention, when an insertion is commanded, the command is stored in the input command register 20 by instructing the insertion from the input unit 10. In response to the insertion command, the cursor generating section 23 first compares the position and position of the line 0 character at the insertion position with the information in the calibration screen display information section 17, and notifies an error if the position does not contain a character. If it is correct, the size of the cursor is
Find Y, and if the insertion position is in the line as shown in Figure 7(a),
Display position of cursor 50 at insertion position (Xl, Yl)
From, X2 =X+ (X/20PX), Y2 =
Y+ (where Px is the inter-character pitch) is calculated, and the cursor 50 is displayed from this display position.

In addition, when the insertion position is at the beginning of the line as shown in (b), a space 52 is provided at the beginning of the line in advance, and the display area If of the cursor 50 at the beginning of the line is
(X3, Yl) yo'), X4 =X3-X/
2. Calculate Y<=Y3 and move the cursor 50 from the display position
Display. Note that the space only needs to be a half-width valve of the maximum font size to be displayed.

Next, by inputting an insertion character string from the input unit 10, the input insertion character string is stored in the input buffer 27 and sent to the display control unit 18 and the proofreading processing unit 28. The display control section 18 displays the inserted character string at a predetermined position on the display section 19, while the proof processing section 28 displays the line register 21 and character position register 2 for the document data in the document buffer 15.
The inserted character string is inserted and rewritten from the position indicated by 2. The rewritten document data is sent to the proof screen display information creating section 16, new proof screen display information is created, and the inserted data is displayed on the display section 19.

The document data configured and edited in this way is saved in the document file 13 by commands from the input section 10.

[Effects of the Invention] As described above, the present invention enables accurate and easy scrolling to a desired location by sequentially searching for a desired character string and character strings that appear before the desired character string and performing line scrolling. This improves the efficiency of proofreading and editing work.
