Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a document processing device that processes document data of characters, figures, and images, and in particular, includes latent data in a document displayed in a layout, and processes the data as necessary. The present invention relates to a document processing device capable of calling up and displaying and editing.

[Prior Art] In a conventional word processor, the storage position, display position, and print position of input data are determined. For example, the storage position and display position of input data are determined based on the location where a cursor is placed. When creating a document using such a device, it is generally convenient to handle data that is common to each page, such as headers and footers, in a separate frame from the original document data, but when creating a document using a conventional device, the header of each page I had to type in the same data for each item.To avoid this, it is possible to specify the common items for each page all at once, but if you do that, the specified data will be valid for all vanes, and you can change the header or other data from a certain page. The footer cannot be changed.One way to solve this problem is to embed control data for the header and footer in a pile of text and 1!j data, like conventional computerized phototypesetting machines, and process them all at once.However, With this method, even if you want to modify the control data later, it is difficult to find the embedded control data and the t and ν information of the header and footer. The drawback was that it could not be done.

[Objective 1] The present invention has been made in view of the drawbacks of the prior art described above, and its purpose is to facilitate the handling of such common data and to facilitate its modification and editing, thereby improving the total An object of the present invention is to provide a document processing device that has significantly improved document editing ability.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram of a document processing apparatus according to an embodiment of the present invention. In the figure, ■ is a CRT display unit using the rask scan display method, 2 is a video RAM (VRAM) that stores one screen of pattern development information, and 3 is a VR
A display control unit controls pattern expansion to AM2 and pattern readout to CR7 display unit 1, 4 is a microprocessor (MPU) that controls the main control of the device of this embodiment, and 5 is a ROM containing a control program. and a main memory consisting of a RAM for data processing, 6 an external magnetic disk device storing document files, etc., 7 a pointing device (FD) for inputting display screen position specifications, 8 a keyboard, 9 is an I10 hash that connects each of these blocks and the MPU4.

FIGS. 2(a) and 2(b) are diagrams showing an example of a data sequence handled in this embodiment. The data input string includes control data in addition to character data. The same figure (a
) is the control data h1 of the header string start in the data input column.
．． Header string H, header string end control data h2
This is an example of a case where One use of a word processor using the invention! According to Mr. Le, this control data h,,h
When pair 2 arrives, the headers on and after the page currently being created are automatically replaced with the header character string H. Therefore, by embedding this control data in the document data of an appropriate page, the header can be updated without having to input the header for each page.

FIG. 3B shows an example in which the data input string includes control data for page number preset. In this case, after the normally used page break control data PE, control data P+ for starting page number presetting, page number /<P, and control data p2 for ending page number presetting are included. Similarly, according to one mode of use of a word processor using the present invention, when this set of page number preset control data pHP2 appears, a new page number /<P The value is set from .

Figures 3(a) to (d) show the data input column in Figure 2 as CR7.
FIG. 3 is a diagram showing a case where it is displayed on the display unit 1. FIG. Figure (a),
(b) is a diagram when the data column of Figure 2 (a) is displayed, and the header display "O〇-Roro" on the nth page of Figure 3 (a) is the same as +1A (b). : The header display has changed to FAA-XXJ due to the header control data h, , H1h on page ftJn+1 (shows E). However, the actual header control data h, , H, h2 are not displayed in the header. Since it does not exist at the position, the control data h
, ,H, to indicate the location of h, the symbol Fu is a sentence,! ) is displayed at the appropriate position.

Figures (C) and (d) are diagrams obtained by reducing the data in Figure 2 (b), and even though the page number is displayed as "25" in the upper right of Figure 3 (c), the In order to include control data Pl, P, and P2 for page number preset in the data input column of the vane, the page number is displayed in the upper right corner of the next vane.
1" is displayed, and subsequent pages show a state in which the number increases as 2, 3, 4, and so on. In this case as well, since no control data exists at the position where the page number is actually displayed, the symbol (
It's displayed at the top left of my page.

With this kind of relationship between document data and symbol display, sentence 1! ) It is possible to insert control data into document data without destroying the overall display layout, and the position of the control data can be easily known. In addition, control data can be manually entered at appropriate positions depending on the context of the document data, such as by updating the header midway.

Figures 4(a) and 4(b) are diagrams showing a method of calling the header character string H of FIG. 2(a) via the display 1m of FIG. 3(b). Symbol display (h) in Figure 4 (a)
When you point to the cursor using the PD7, the same figure (
As shown in b), the header data H that was potentially included in the symbol display (world position) is read out, and the FAA-
Appears as the north riding display of XXJ. PD7 can be used as keys for moving the cursor, but it can also be used as a light pen,
A joystick, trackball, mouse, etc. can be used.

FIG. 5 is a block diagram showing the configuration of FIG. 1 divided into functions. In the figure, document data from a data supply source 10 consisting of a keyboard 8 and a disk device 6 is transmitted to a control means 4.
1 to the page processing means 42. The page processing means 42 handles line breaks included in the read document data string,
In accordance with various format control codes such as page breaks and offsets, a table is created that corresponds to pattern development addresses in the VRAM 2 and manual liberal arts codes, and is stored in the page address table 5■. In this case, the data hl related to the header control described above.

The H and h2 parts are represented by symbols ('Fv
It can be replaced with the following code. However, the replaced header control data h, , H, h2 is stored at an address that can be referenced at any time by pointing out the symbol display (~) by operating the PD 7. In this way, it is stored in the page address table 51. The created document data is immediately read out for display and processed by a character generator (CG).
At step 31, the pattern is converted and expanded to the VRAM2. The main memory 5 also contains header control data hl+h2, header character string H1 control data PI, P2 . Page number P,
It is provided with registers 52 to 60 for storing Y coordinates, X coordinates, offsets, and quantities.

FIG. 6 is a diagram showing the structure of the page address table 51. In the figure, yo and Xo are data giving the X coordinate and X coordinate of the first character position 1ξ of the line, and ofstl is data giving the offset of the X coordinate from the first character position of God. In this case, the most significant bit of ofstl is OFF to indicate that it is an offset from the first character position. Also, when there is header control data indicated by (■), the X coordinate offset afstiI becomes the offset value of O and does not affect the display position of the next character, and the most significant bit of ofstil in this case is turned ON. There is.

FIG. 7 is a Fuco chart showing the processing procedure of this embodiment described above. In step St, it is determined whether or not there is manpower available for document data. If there is data input, step S2
reads the data and sends the data to the page processing means 42. The page processing means 42 determines where on the VRAMZ the data is located in step S3,
In step S4, the obtained coordinates of the VRAM 2 and their code data are stored in the page address table 51. Next, in step S5, the code and the expansion address on the VRAMZ are displayed on the display control unit 3 according to the page address table 51.
The upward 0 display control unit 3 sends a pattern corresponding to the code to the given position on the VRAMZ in step S6.
1, the data is expanded and displayed on the CRT display section l, and the process returns to step S1.

Further, if it is determined in step Sl that data is not input, the input from PO2 is checked in step S7, and if there is no data input, the process returns to step S1 again. Also, if there is an input for PO2, press
The cursor position coordinates indicated by O2 are read in step S8. In step s9, the page address table 51 is searched from the coordinates of the cursor position, and in step slo, the corresponding coat data is checked. If there is no corresponding data or if the data is data other than control data (character data), the process returns to step S1. For example, if this is the symbol data D of the header control data, the symbol data (corresponding character data string FAA-XXJ
is determined, the CG 31 is activated with the display address and character code following the symbol data (■), and the data is expanded onto the VRAMZ. As a result, a header control data display FAA-XXJ is obtained on the CRT display section 1. In this way, this data is fully realized.”
It can be easily modified by following the method. The same applies to the case of presetting to the page number.

[Effect] As described above, according to the present invention, specific data in the document data that cannot be displayed in the same line as other data is represented by a symbol at an appropriate position in the document data, so that the entire document The storage location of specific data can be easily known without destroying the display layout. Further, when modifying the specific data, the corresponding specific data is called up and displayed at the position of the symbol display by instructing the symbol display on the screen, so that it is easy to modify the data. Therefore, for example, a word processor equipped with the present invention can easily and diversely handle common data such as headers, footers, page numbers, etc., and can also easily modify and edit the data, thereby significantly improving the total document editing ability. can.
