Abstract

PURPOSE:To produce a document with extremely high efficiency by displaying plural types of documents on the same screen by a multi-window display technique. CONSTITUTION:It is possible to display >=2 types of documents on a screen 57 of a CRT by a multi-window display technique. At the same time, ''misdeeds of youth'' within a memo pad window is shifted into a main window after ''recent'' is fed into the main window. Thus ''recent misdeeds of youth'' is displayed within the main window with no reinput of ''misdeeds of youth''. This can increase greatly the efficiency for production of documents.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an improvement in a document input method in a document processing device such as a Japanese word processor.

<Technical background of the invention and its problems> Generally, when creating a certain text, first list out the outline (gist) of the text you want to create in a memo pad etc.
Afterwards, it is normal to create the actual text while referring to those notes.

On the other hand, conventional word processors can only handle one document at a time, and cannot handle multiple types of documents simultaneously on the same screen. Therefore, when creating a certain sentence, for example, as shown in Figure 1 (a) [
As shown in Figure 1(b), first create a memo l listing the summary items of the text by hand on a word processor, then write the actual text on the display screen 2 of the word processor while looking at memo 1 as shown in Figure 1(b). The method used was to create

However, according to such a conventional method, the memo pad 1 and the document to be actually created that is displayed on the display screen 2 of the word processor are located at separate positions, resulting in a problem that the operator's line of sight has to shift considerably. Also, when creating a memo pad and when creating an actual sentence, it is necessary to input the same concept (same word, same phrase) again, which is very wasteful in operation and wasteful in writing. The problem was that a lot of time was wasted.

Also, in conventional word processors, it is possible to move information from one document to another, but in this case, first call up one document on the screen, then select the part you want to transfer (
This is an emergency procedure where you specify a region and temporarily register a paragraph, then delete this Bunzuri and call up the other document on the screen, and then specify the place in the document where you want to insert it and call up the temporarily registered paragraph. required time-consuming operations.

<Object of the Invention> An object of the present invention is to provide a document input method that eliminates the above-mentioned problems and can provide a word processor with excellent operability. The documents are displayed on the same screen, and each document displayed on the same screen can be entered independently, and information including character strings can be moved from one document to another. .

<Embodiments of the Invention> Hereinafter, an example in which the present invention is applied to a Japanese word processor will be described as an example. However, before going into a specific explanation of the embodiments of the present invention, it is important to explain the First, window display technology will be explained.

Multi-window display technology is a technology for simultaneously displaying multiple types of information in a superimposed manner on a display terminal device of an information device, thereby making it possible to view two or more types of information simultaneously on the same display. In this case, since two or more types of screens are overlapped at the same time, a necessary portion of the display content of one screen may be hidden by the display of the other screen.

To avoid this, these windows can be moved anywhere on the display screen and deleted at any time according to the user's instructions.

Next, a specific example for realizing the VC77-window display function will be described, but various means for realizing the multi-window display function can be considered, and the present invention is not limited to this.

FIG. 2 is a block diagram showing the principle of a multi-window display function in a so-called bitmap CRTK.

In FIG. 2, 10 is a central processing unit (CPU), 11

), ] 3 is a frame memory for several screens having storage elements corresponding to the display on the CRT one dot at a time, 14, 15 and 16 are frame memories for one screen each comprising the frame memory 13i, and 17 is a frame memory for one screen of the CRT. This is the display screen.

Also, address (pl, ql, r1+ s+) and (ul
.

'V(+w]lX]) are the addresses of the four corners of each window of the frame memories I5 and I6, respectively, and each of these address information is held in the window controller (WDC) 12.

Also address (1)2. q2+ r2+ s2) and (
u2°V2 + w21 X 2 ) are respectively the above addresses (pH, q.

171181) and (ul, vllwl, Xl) are the addresses of the four corners of each window on the CRT screen 17 that supports VC, and each of these address information is also held in the window controller (WDC) 12.

Furthermore, the window controller (WDC) +2i holds display priority information between each window, and in the example shown in FIG.
s), that is, the order of frame memory+6.15.14 is maintained.

In the above configuration, the CRT controller (CR
TC) 11 is a window controller (WDC) ■2 holds the frame memory 15 and each window address information of I6 mentioned in 1, each window address information and display priority information on the CRT screen 17 as well as a frame memory. Each frame memo 'J' 14, 15, and 16 in 13 is selected as appropriate and its stored contents are read out, and the contents are displayed on the CRT screen 7 as shown in Figure 2 above.

In addition, by appropriately rewriting each of the above information held by the window controller (WDC) 12 according to instructions from the CPU10, the display on the CRT screen 17 can be changed to
(c) It becomes possible to easily change as shown in K.

That is, by rewriting the window address on the frame memory 13, the display within the window can be scrolled. For example, window address (111, V 1+
By raising w1 +
The display within the window is scrolled as shown in K0. Furthermore, by rewriting the window address on the CRT screen 17, the window can be moved. For example, the window address (u 2 + 'V 2 * W2 , x
2) by one line (decreasing each y-coordinate of the window address by one line) to create C as shown in Figure 3(b).
The window on the RT screen 17 is moved.

Furthermore, the priority order of the window is changed, for example, the priority order of the window address t (p+ q+ rt s) (
u.

v, w, x), the display can be changed as shown in FIG. 3(c) VC.

By using multi-window display technology in this way, the dot patterns in the frame memo January 4 to 16 are completely removed even when the screen display is drastically changed as shown in Figures 3 (a) to (c). There is no need to rewrite, and only a few parameters such as the window address held in the window controller (WDC) 12 need to be rewritten.

Therefore, display changes such as those shown in Figures 3(a) to (c) can be made in a short time within one frame time (usually about 1/30 second), which may give the user a completely strange feeling. There is no.

Note that even with a normal display device that does not have a multi-window display function, the display shown in FIGS. 3(a) to 3(c) can be changed by rewriting the contents of the frame memory 14 each time. Note that in this case, it takes more time to switch the display than when using multi-window display technology.

Next, an embodiment of the present invention using the above-described display technology will be described in detail.

FIG. 4 is a block diagram showing an embodiment of the present invention applied to a Japanese word processor. In FIG. 4, 50 is a central processing unit (CPU), 51 is a CRT controller (CRTC), and 52 is a A window controller (WDC) provided in the controller (CR, TC) 5 ] of this CR'T, a frame memory with a storage capacity of several screens corresponding to the display on 5 & RT one dot at a time,
Reference numerals 54 and 55 are display screens of frame memos IJ and E+7UCRT, respectively, which constitute one screen of the frame memory 53. Further, 58 is a keyboard, and the keyboard 58 has an arrangement of all characters including Kanji characters.

In this case, the keyboard 58 may be configured as a kana keyboard, and a function for performing kana-kanji conversion processing via a kana-kanji conversion dictionary may be added to the main body of the device.

Reference numeral 60 denotes a character generator, 6114 and a character code buffer memory corresponding to the frame memory 53, and this character code buffer memory 61 has character code buffer memory sections 62 and 63 corresponding to the frame memories 54 and 55. It is also a screen position indicating device such as a 64-inch mouse or a light pen. Reference numeral 65 is an external memory such as a floppy disk, and the document once created is stored in the memory 65.

Next, the operation of the apparatus configured as described above will be explained with reference to the operation flow diagram shown in FIG.

First, in step n1 of the operation flow shown in FIG.
It is understood by Specifically, the operator instructs to set the domain of the memo pad window by specifying a position on the display screen 57 using the keyboard 58 or the mouse 64.

Also, display the memo pad window area at the bottom left corner of the screen 57.
It may be configured to be fixedly set in advance for four screens.

The CPU 5 (1-J), which has grasped the domain of the memo pad window specified in step n1, then sets the window address (pH, q, etc.) based on this definition.

rl, 8.1) and (1) 2+ q2+ r2+ 82
) and its contents as window controller CWD
C) Load 52Kg (Step 1. Step H2, n3). Furthermore, in step n4, the display priority between windows is changed from frame memory 55 for memo to main frame memory 5.
It is set to give priority to 4.

In this state, the input cursor is located within the memo pad area.

Next, in step n5, it is determined whether there is an instruction to change the input location. This instruction to change the input location is provided, for example, on the keyboard 58 with a )' (7:l% (7) shift) key 58a, and depending on the key operation of this key 58a, the input cursor position is moved between the memo pad area and the main area. Alternatively, the switching may be performed by indicating the position of a predetermined area using the mouse 54. If an instruction is given to change the input location while the device is in the mode (■) for specifying the memo pad area, this change instruction is determined in step n5, and the device shifts to the mode (■) for specifying the main area.
From now on, input to the main area is possible. Also, if you specify a change in the input location while the device is in the mode (■) for specifying the main area, this change instruction is determined in step n14, and the device shifts to the mode (■) for specifying the memo pad area. Enables input.

Therefore, when inputting into the memo pad, after confirming that the 1d device is set to mode ■, operate the keyboard 58 to input the desired character string (step n7),
The character code input from the keyboard 58 is recognized by the CPU 50 (n8), and the character code is written into the character code buffer memory 6'3K (n9), and the corresponding character pattern is read out from the character generator 60 and stored in the frame memory. 55 (nlO
). The information written in this frame memory 55
It is immediately displayed in the memo pad area on the display screen 57 by the multi-window display function described above under the control of the C51 and WDC52.

When inputting into the memo pad is completed, the user moves on to inputting the actual text into the main area, but in this case, the user first instructs to change the input location (n5), and then switches the device to the main area specification mode (■). .

If the keyboard 58 is operated after switching to the mode (2), the input from the keyboard 58 will be performed in steps n16 to n1.
9, the character code is written to the character code buffer 1 memory 62, and the character pattern is written to the frame memory 54 and immediately displayed in the main area of the display screen 57, as in the case of the memo pad. become.

As described above, input can be made independently for each document of different types in the main area or memo pad area.

Next, the operation when specifying a character string in one document and moving the character string to a desired position in the other document will be described.

Now, when a desired character string or the like in the main area or memo pad area is specified using the mouse 64 or the like (step n6 or Un15), the specified area on the CPU 501-1 display screen 57 is grasped (nl 1 ), Window information (
P1+ q1+ r1+ s, ) (p2. q2s r
2., s2) and the display priority information to determine whether the specified area is for the frame memory 54 or 55 (nl'2), and based on the result of this determination, the character code buffer memory 62 or The corresponding character code string designated by the area on 63 is recognized (n13).

Next, when the operator specifies a desired insertion position in the memo pad area or the main area using the mouse 64 or the like (n20), the CPU 50 grasps the specified position on the display screen 57 and uses the window controller (WDC) 52. Window information held within (p1+ q1+ rl+
5l) (p2・q2+r2+s2) and the display priority information to determine whether the specified position is for the frame memory 54 or 55n21), and based on this determination result, the character code buffer memory 62
Or the specified corresponding position on 63 is grasped (
n22).

Next, the process moves to step n28, and the character code string on the character code buffer 7 memory 62 or 63 recognized in step n13 is transferred to the corresponding position on the character code buffer memory 62 or 63 grasped in step n22. The character pattern is then read out by the character generator 60 and written into the frame memory 54 or 55 (n24).

Through the series of operations described above, a character string is moved from one document area to another document area.

As mentioned above, the position on the memo pad window or the main window is specified using the screen position indicating device 64 such as a mouse or a light pen, but these outputs are usually absolute coordinates on the screen, and it does not matter which window It is not possible to immediately determine whether it belongs. However, according to the above-mentioned embodiment, as a parameter defining the window on the CPU 50 side, (p1+ qlt r1+ slL
(p2+Q2+r2+s2), the absolute coordinates on the screen are stored in the frame memory 54 or 55.
It can be easily converted to the above address, and the frame memories 54 and 55 and the character code buffer 7 memory 62
and 63 have a one-to-one correspondence, so as a result, specifying the position of the mouse 64 is equivalent to specifying the positions of the character code buffer 7 memories 62 and 63.

Through the above operations, two or more types of documents are displayed on the same display screen 57 using the multi-window display function as shown in FIG. Also, specify an area in the memo pad window and specify "Youthful Delinquency," then specify a position in the main window, enter "Youthful Delinquency" in the main window, and then use the keyboard to select "Recent By inputting iI and further inputting "youthful delinquency" in the main window using the above operation, you can avoid re-entering the same concept ("juvenile delinquency").
Text can be created extremely efficiently in the main area by effectively utilizing the character strings in the memo pad area.

Also, the memo pad window may get in the way when you are actually creating the text, but in this case, the window address (p2 + q2 * r2 + s2) can be rewritten using the multi-window display conversion technology mentioned earlier. This allows you to move the Notepad window to any position. Furthermore, the window address (PH+91+r
By rewriting 1+s+), it is also possible to scroll within the notepad window and display ``competition for higher education'' and ``dropout''.

Note that although the above embodiment has been explained using a memo pad and an actual text as an example, the present invention is not necessarily limited to this as long as there are two or more documents. For example, one of the sentences may be a document stored in an external memory such as a floppy disk 65, and in this case, it is possible to move not only the same words and phrases as in a memo pad, but also paragraph units, and the same concept can be moved. The effect of saving re-input is even greater.

<Effects of the Invention> As described above, according to the present invention, multiple types of documents can be displayed on the same screen, and input can be made independently to each document displayed on the same screen. Since information including character strings can be moved from one document to another, documents can be created extremely efficiently.
