Abstract

PURPOSE:To easily edit plural document data edited at separated positions by displaying partial document data including a part whose editing position is instructed out of the document data being displayed before forming an area at a prescribed display area, and displaying the document data in an arbitrary area in a storage means at another display area. CONSTITUTION:When it is required to refer to the document data not being displayed on a display means b, a display control means c forms plural display areas on the display screen of the display means b replying to an instruction, and displays partial document data including the part whose editing position is designated out of the document data displayed before forming the area at the prescribed display area, and displays the document data in the arbitrary area in the storage means a at another display area. Therefore, an editing processing can be performed at any display area by indicating the display area arbitrarily by an indicating means d. In such a way, it is possible to easily edit the plural document data edited at the separated positions.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a document editing device such as a Japanese word processor, and particularly to a document editing device such as a Japanese word processor, and particularly to a device for editing a document while referring to document data different from the document data to be edited. The present invention relates to a suitable document editing device.

[Prior Art] Generally, when creating a document by hand, the document is often created while appropriately referring to pages of the document that have already been created and checking for uniformity of terminology, consistency of context, etc.

If you tried to do something similar to this using a conventional Japanese word processor, you could do the following.

The first method is to change the displayed content by performing a scroll operation, etc., find and confirm the document data you want to refer to on the display screen, and then display the document data that is being created again by scrolling, etc. to process the document creation process. This is a method of creating a document by continuing to do this and repeating this process as necessary.

The second method is to set an arbitrary area on the document data,
This is a method of creating a document by displaying the document data in this area as reference data on a part of the display screen. In this method, as in the first method, first, perform a scroll operation etc. to switch the display contents, search for the document data you want to refer to on the display screen9, and then specify a range of the found document data you want to refer using a cursor etc. By specifying with a cursor or the like where on the display screen the reference data in this range is to be displayed, the document data to be edited and the reference data are simultaneously displayed on the same display screen.

[Problems to be Solved by the Invention] However, the first method requires repeated display switching between reference data and document data to be edited, and requires complicated key operations. Furthermore, it is not possible to simultaneously display the reference data and the document data to be edited on the same display screen, which is inconvenient in terms of comparing and checking the two.

On the other hand, the second method simultaneously displays the other reference data on the display screen and the document data to be edited, and displays the reference data in the same one! Although there is an advantage that document data can be created while referring to screen ii-L, the operation for simultaneously displaying the reference data and the document data to be edited on the same screen J-1l is extremely complicated.

Further, editing processing is possible only in a display area where document data to be edited is displayed, and editing processing is not possible in a display area where only reference data is displayed. Therefore, for example, even if it is determined that the reference data should be corrected after comparing and refining the document data in the image display area, it is difficult to correct the reference data if both data are displayed simultaneously. If you are unable to do so, you may need to make corrections by displaying only the reference data part on the entire display screen, then switch the display to only the original document data to be edited again, or perform the complicated operations described above. Therefore, it is necessary to simultaneously display the reference data and the document data to be edited on the same display screen again, which is troublesome, so the simultaneous display function has been avoided.

An object of this invention is to be able to simultaneously display multiple pieces of document data that have been edited at separate locations on the same display screen, and to be able to edit any of the document data that is being displayed simultaneously. It is to do so.

[Means to solve the problem] The means of this invention are as follows.

The storage means stage a (see the functional block diagram of FIG. 1, the same applies hereinafter) stores document data.

Display means 1] displays part of the document data stored in storage means a.

In response to a predetermined instruction, the display control means C changes the display level 1 to 1-.
), multiple display areas are formed on one display screen, and a predetermined display area displays part of the document data that was displayed before the area was formed, including the part for which the editing position was specified. and other tables, 1. area (, 9 for displaying document data in an arbitrary area in storage means a; designation means d is formed by display control means C); Arbitrary Designation of Display Area 9 1 Operation] The operation of the means of this invention is as follows. Assume that you have given a predetermined instruction because it becomes necessary to refer to .

Then, in response to the instruction, the display control means C,
A plurality of display areas are formed on one display screen of the display means 1], and a part of the document data that was displayed before the area was formed, including the part for which the editing position was specified, is displayed in a predetermined display area. , and document data in an arbitrary area in the storage means a is displayed in other display areas.

Therefore, the editing process is performed by comparing the document data in each of these display areas. At this time, if the document data displayed in the reference area is not corrected, the document data displayed in the reference area should be edited. The data display area may be designated as the display area to be edited by the designation means d, and correction processing may be performed.

That is, by arbitrarily specifying a display area using the specifying means d, editing processing can be performed in any display area.

Therefore, a plurality of document data edited at separate positions can be displayed simultaneously on the same display screen, and editing processing can be performed on any document data that is being displayed simultaneously. One embodiment will be described with reference to FIGS. 2 to 7.

FIG. 2 is a block diagram of the document editing device.

This document editing device performs document editing processing with the CPU as the core, and in addition to the CPU, it also includes a key human power section 2, a document memory 3, an editing control section 4, a display section 5, a screen memory 6,
Display control unit 7, Kurtarboink P, and work RAM
It has 8. Note that the display screen of the display unit 5 is a 20-line display.

The editing control section 4 responds to the key operation of the key human power section 2,
Various editing processes (document creation processes) such as insertion, deletion, and movement are performed under the control of the CPUI, and the editing results are stored in the document memory 3. At this time, the CPUI causes the screen memory 6 to update and store one screen worth of document data to be displayed on the display section 5, and the display control section 7 controls the display of the contents stored in the screen memory 6.

The cursor pointer P specifies the display position of the cursor for specifying the position of document data displayed on the display screen of the display unit 5, and the display control unit 7 moves the cursor to the position specified by the cursor pointer P. Display.

The key input unit 2 includes a data input key 2a for inputting various document data, and a cursor key 2 for instructing movement of the cursor.
In addition to b, reference key 2C, search key 2d, switching key 2
It has various function keys such as e and release key 2f.

The reference key 2c is a key for instructing to search and display the specified input search target character (referred to as one or less search specified characters including a character string).

That is, when the reference key 2c is operated, the 20-line display screen of the display unit 5 is divided into two vertically under the control of cpul, and the lower screen displays the line whose position was specified by the cursor at the time of division. Half a screen worth of document data including
On the lower screen, 10 lines of document data centered around the search specified characters searched on the document memory 3 are displayed.

The search key 2d searches for the next search target character string,
This key is used to instruct the display contents of the lower screen to be changed based on this.

The switching key 2e allows the lower screen,
This key is used to specify the lower screen to be switched arbitrarily.

The release key 2f is a key for canceling the split screen and returning to the normal 11 screens.

In addition, when performing the above-mentioned screen division processing, etc., the main start line storage area ST, main end line storage area EN, search specified character storage area SER,
Edit position storage area EDT, auxiliary position storage area SUB
, the main screen editing flag F is utilized. Note that the editing position storage area EDT stores position data on the document memory 3 of document data designated as an editing target with a cursor on the display screen. Furthermore, when the main screen editing flag F is turned on, editing is possible on the lower screen, and when it is turned off, editing is possible on the lower screen. The data stored in each of the other areas will be explained along with the operation.

Next, the operation of the embodiment will be explained with reference to FIGS. 3 to 7.

First, the split display processing based on the operations of the reference key 2C and search key 2d will be explained with reference to FIGS. 3 and 4.

After operating the reference key 2c, when one or more desired search characters are specified using the cursor keys 2b (step SL in FIG. 3), the CPU stores the specified search characters in the work RAM 5. Step S2). Next, cursor pointer P is 1
Whether or not it indicates a line after line 0, that is, 10
It is determined whether a character in a line after the line has been specified as a search character (step S3).

As a result, if a character in a line after the 10th line is specified as a search character, the search result is found in the document memory 3 corresponding to the first line of the currently displayed page, which is the current content of the main start line storage area ST. Add 10 times the totality Nα (Step S4).

On the other hand, if characters in lines 10 and earlier are specified as search characters, the document memory 3 corresponds to the last line of the currently displayed page, which is the current content of the main end line storage area EN.
Multiply the above summation Nα by minus 10 (Step S5)
.

Next, the display contents are cleared once and the display screen of the display unit 5 is divided into two upper and lower parts, and the totality N in the main start row storage area ST is
The document data in the document memory 3 sandwiched between α and the summation NO in the main end row storage area EN is displayed on the divided child screen.Step 56)9 Here, Steps S4 and B5
, B6 will be specifically explained based on FIG.

As shown in FIGS. 4 (A1) and (B1), when the contents of page 5 are displayed, the main start line storage area s'
The total row number corresponding to the first row of the page in r2 The totality number corresponding to the last row of the page in the main end row storage area EN are "
81 ``,'' ] OO'''9 and,
1 on the display screen, as shown in Figure 4 (A], ).
When the character on the 5th line is specified as the search character, the commensurability Nα”8] of the main start line storage area ST1 No.
" is incremented by 10 to become '91', and the totality Na "100" in the main end row storage area FAN is maintained as it is. Therefore, the content in the lower half of the display screen shown by hatching in Figure 4 (A] j will be returned to its original position (child screen).
is displayed, and nothing is displayed on the main screen (Figure 4 (A)
2)).

Furthermore, as shown in FIG. 4(B)), when the character in the fifth line on the display screen is designated as the search character, the summation value Nα in the main end line storage area EN is ``100''. is subtracted by minus 10 and becomes '91', and the summation number "8 ] '" in the main start row storage area ST is maintained as it is.Therefore, as shown by hatching in Figure 4 (B1) of the display screen 2. The contents of the second half of the screen are displayed on the sub screen, and nothing is displayed on the main screen (see Figure 4 (B2)).
.

In this way, of the document data displayed as an editing target, half a screen worth of document data including the designated search character is displayed on the divided child screen.

Next, the document memory 3'2 is searched for the search specified character toward the page preceding the currently displayed page (step S7). Note that this search may be performed toward a page after the currently displayed page. Then, the position data of the search specified character is stored in the auxiliary position storage area SUB.
In step S8), document data for 0 lines centered around the retrieved search specified character is displayed on the divided main screen (step S9). Next, the position data of the display screen corresponding to the edit position data on the document memory 3 set in the edit position storage area EDT is calculated, and the calculated position data is stored in the cursor pointer P. (
Step S]-〇), the process moves to editing processing on the child screen.

Note that the significance of this step 81.0 will be described later.

When the search key 2d is operated, the screen edit flag F
Step S1]
, ) If it is turned on, editing on the main screen is possible as mentioned above, so the search specified characters can be entered in the direction before the current class book specified position in the document memory 3. search step 512). Then, the position data of the retrieved search specified character is stored in the editing position storage area EDT (step S], B3)--the process proceeds to step S9.

On the other hand, if the main screen flag F is turned off, editing on the sub screen is possible, so enter the search specified characters toward the front of the auxiliary position indicated by the current auxiliary position storage area SUB. search step 514). Then, the position data of the search specified character is stored in the auxiliary position storage area SUB (step 515), and the
Proceed to step 9.

Here, the significance of step S10 will be explained. For example, when a character in the output screen part is specified as a search character as shown in FIG. 4 (B1), the document data in the output screen part that includes the search character is The screen is moved and displayed on the lower split screen as shown in FIG. 4 (B2). Therefore, as it is, the cursor pointer P specifies a character other than the search character, so this is done to initially specify the search character as the character to be edited using the cursor on the sub-screen. Furthermore, when a search specified character is searched in response to the operation of the search key 2d and the display of the main screen is switched based on the search result, the process of step S10 is performed for the same reason.

Next, the process when the release key 2f and the switching key 2e are operated will be explained with reference to FIG. Step 551) The summation Nα in the area ST is subtracted by minus 10. Then, the document data in the area on the document memory 3 sandwiched by the summation Nα in the main start line storage area ST that has been subtracted by 10 and the summation Nα in the main end line storage area EN is displayed on the entire screen ( Step 552).

That is, by operating the release key 2f, a normal single screen without division is displayed.

Next, it is determined whether or not the main screen editing flag F is turned on (step S5B). If it is turned on, the main screen editing flag F is turned off (step 554). and,
The contents of the editing position storage area EDT and the contents of the auxiliary position storage area SUB are exchanged (step 555), and then the document memory 3 indicated by the editing position storage area EDT is replaced.
The position data on the display screen corresponding to the above editing position data is calculated and stored in the cursor pointer P (step 556), and the process ends.

If it is determined in step 353 that the main screen editing flag F is not turned on but off, step S54
, the process immediately proceeds to step S56 without passing through step S55.

Further, when the switching key 2e is operated in a state where the screen is divided vertically, it is determined whether or not the main screen flag F is turned on (step 557). If it is turned on, the process proceeds to step S54 and the main The screen editing flag F is turned off, and if it is not turned on, the main screen editing flag F is turned on in step 958, and the process proceeds to step S55. In other words, by operating the switching key 2e, it is possible to arbitrarily switch the split screen to be edited upward or downward.

Next, the processes shown in FIGS. 3 and 5 will be explained in detail with reference to FIG. 6.

Now, in the document memory 3, as shown in FIG. 6(A),
It is assumed that document data from page 1 to page 5 is stored. In addition, the part indicated by the opening in FIG. 6 is a search designation character, and the numerical value indicates page Na. .

Then, as shown in Fig. 6 (R) (■), if you operate the reference key 2c while page 5 is displayed, the display screen will be divided into two parts, and a sub-screen will appear.]-7 is the search specification. The bottom 10 lines of document data of 5 pages containing characters are displayed, and the main screen displays 10 lines of document data centered on the search specified characters of 4 pages in document memory 3 (6th (See Figure (B) ■). In addition, Figure 6 (
In B), ``■'' indicates the search specification character currently specified with the cursor to be edited.In other words, if the display screen is divided into two, ``■゛' exists. The other split screen is an editable screen.

If you operate the search key 2d in this state, the specified search characters will be searched toward the pages before the 4th page, but as shown in Figure 6 (A), the specified search characters will be searched for on the 3rd page. Since there are no characters, 10 lines of document data centered on the search specified characters from the previous two pages are displayed on the main screen, as shown in Figure 6 (B) ■, and the display contents on the sub-screen are remains fixed.

When the release key 2f is operated in the state shown in Fig. 6 (B) ■,
As shown in FIG. 6(B) 8, the screen division is canceled and all the contents of the original five pages are displayed on one screen]8.

On the other hand, if the switching key 2e is operated in the state shown in FIG. The cursor position is specified at the display position corresponding to the original auxiliary position (position of the search specified character). Therefore, as is clear from ``'' shown in ``■'' in Fig. 6<B), the cursor is moved to the search designation character on page 2 displayed on the bivalent surface. Zunawaji, the displayed content remains fixed and cannot be edited, but the split screen (to be edited) is switched from the bottom side to the top side.

If you operate the search key 2d in the state shown in Fig. 6 (B) ■,
As shown in Figure 6 (B) ■, the display content on the bottom side remains fixed, and the top side displays 10 lines of document data centered on the search specified characters on page 1, which is 2 pages before page 2. is displayed. In addition, as shown in Figure 6 () 3) ■,
If you operate the switching key 2e while the top surface is the subject of editing, the displayed content remains fixed and the surface to be edited is switched from the bivalent surface to the bottom surface (Fig. 6-1). )■
reference).

Also, as shown in FIG. 6(B) (■), when the release key 2e is operated while the upper surface is being edited,
Similar to when the lower side is the subject of editing, the screen division is canceled and all the contents of the original five pages are displayed on one screen. However, when canceling this screen division, if characters in the upper half of the original page 5 are specified as search characters, as can be inferred from the process in step S51 in FIG. The document data in the area and the document data in the first half area of page 5 of the relevant environment are displayed on one screen.

In this way, with a simple operation, you can switch to display half a page of the document data of another page that contains the search specified characters on the upper side of the divided page, and display the half page that contains the search specified characters of the page you were editing. The document data can be fixedly displayed on the bottom surface, and the split screen to be edited can be switched vertically or arbitrarily.

Note that the present invention is not limited to the above-described embodiments, and, for example, it is also possible to automatically divide the screen into three or more screens. Also, without automatically splitting the screen,
It is also possible to automatically form so-called multi-windows at predetermined positions.

[Effects of the Invention] According to the present invention, multiple pieces of document data can be displayed simultaneously on the same display screen with simple operations, making it easy to edit while comparing multiple pieces of document data. . In addition, with a simple switching operation, it is possible to edit any document data that is being displayed simultaneously.
You can compare the document data that is currently being edited and the document data that has already been created (edited) displayed at the same time, and you can easily make corrections to the document data that has already been created (edited) according to the comparison results, making it easy to use. is much more favorable.
