Abstract

PURPOSE:To reduce error for setting a bisecting position in the case of bisecting a display picture by displaying a changed firs block area line on third display conditions different from first and second display conditions. CONSTITUTION:In the bisected display picture, the picture frame of a first display picture 12 to display a current picture is displayed by a thick line, and the picture frame of a second display picture 13 to display a non-current picture is displayed by a thin line. When a picture size setting key is inputted, the lower frame of the picture frame of the first display picture 12 is changed into a broken line 16. When a vertical cursor move key is operated, the broken line 16 is vertically moved. When a current picture size decision key is operated at the time point when the suitable size of the current picture is provided, the broken line 16 is changed into the same thick line as the picture frame of the first display picture of the current picture. Thus, the current picture and the non-current picture can be easily identified. Further, the size to set the current picture can be exactly grasped.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention inputs document data,
Regarding a document processing device for editing input document data,
More specifically, 1 or 2 when inputting or editing document data
The present invention relates to a document processing apparatus capable of displaying the respective document data of 2 on a 2-split display screen, setting a 2-split position on the display screen, and a 2-split screen display control device.

[0002]

2. Description of the Related Art In a conventional document processing apparatus, when document data is input and edited on a two-division display screen,
The current screen and the non-current screen are identified by using the screen where the cursor is displayed as the edit screen (current screen) and the screen where the cursor is not displayed as the reference screen (non-current screen). Further, in the document processing device capable of setting the split position of the display screen, as shown in FIG. 12A, the cursor is moved to the screen position desired to be split into two,
By operating the screen division key, a two-division display screen could be obtained at any position on the display screen (see FIGS. 12B and 12C). As described above, the position of the cursor on the display screen plays an important role as a display for distinguishing the current screen from the non-current screen and as a means for determining the position where the display screen is divided into two.

[0003]

However, the split position of the two-split display screen is determined only by the position of the cursor on the display screen as in the above-described document processing apparatus, and the current screen and the non-current screen are determined. There were the following problems when judging. That is, since the cursor is usually small and often rectangular, the cursor may not be clearly identified, and it may be difficult to accurately grasp the current position of the cursor on the display screen. Especially, in the bar-shaped bar cursors, the number of which has been increasing in recent years, the tendency is further strengthened.

Therefore, when the division position for dividing the display screen into two is determined using the conventional document processing apparatus,
It was necessary to determine the 2-split position of the display screen while predicting the 2-split display screen after the 2-split display screen was halved by visually confirming only the cursor position on the display screen. . However, it is often difficult to accurately grasp the cursor position on the display screen. Therefore, by mistakenly setting the split position of the display screen, the non-current screen that you actually want to refer to is reduced and becomes invisible. There was a problem that caused it.

Further, when the current screen is judged by the cursor position on the display screen, it is visually difficult to immediately identify the current screen. Therefore, there is a problem in that the current screen and the non-current screen are confused with each other, various edits such as data overwriting and deletion are performed on the non-current screen, and the reference data is broken, resulting in an erroneous operation. These problems are particularly remarkable after the switching between the current screen and the non-current screen is repeated many times. Further, there is a problem in that the user is overly cautious about an operation because he is conscious of an erroneous operation, and hinders smooth editing work.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to reduce the setting error of the split position when the display screen is split into two. It facilitates screen identification, reduces erroneous operations such as destruction of reference data due to erroneous recognition of the current screen and non-current screen, and improves the operability of the document processing device when editing a document using the two-division display screen, thus ensuring smooth operation. An object of the present invention is to provide a document processing device that enables document editing.

[0007]

In order to achieve this object, a document processing apparatus of the present invention comprises a display capable of displaying 1 or 2 pieces of document data divided on a display screen.
Split display means for dividing the display screen into an edit screen and a reference screen by the first section area line and the second section area line, and displaying one document data on the edit screen and the other document data on the reference screen, respectively. In a document processing device having screen switching means for switching between an edit screen and a reference screen,

Partition area line display means for displaying the first partition area line of the edit screen and the second partition area line of the reference screen in respectively different first display mode and second display mode, and the edit screen And a section area line changing unit for displaying the changed first section area line in a third display mode different from the first display mode and the second display mode. , The first displayed in the third display mode after being changed by the section area line changing means
While setting the editing screen with the division area line,
An edit screen setting unit that switches the display mode of the first divided area line displayed in the display mode to the first display mode is provided as a configuration.

[0009]

According to the document processing apparatus of the present invention having the above structure, one or two pieces of document data are divided and displayed on the display, and the divided display means displays the first display screen.
The division area line and the second division area line divide the edit screen and the reference screen, and one or two pieces of document data are displayed on the edit screen and the other is displayed on the reference screen. The edit screen and the reference screen displayed on the display display are switched by the screen switching means.

The partitioned area line display means displays the first partitioned area line of the edit screen and the second partitioned area line of the reference screen in mutually different first display mode and second display mode. The division area line changing means changes the position of the first division area line on the current screen during the setting of the two-divided position of the display screen, and the changed first division area line is displayed in the first display mode and the second display. It is displayed in the third display mode different from the mode. The edit screen setting means sets the area of the edit screen by the first division area line displayed in the third display manner by the division area line display means, and then sets the display manner of the first division area line to the first display manner. Switch.

The operation of the word processor 1 configured as described above will be described with reference to FIGS. 3 to 11.
First, the split display processing of the liquid crystal display 10 will be described with reference to FIG. At this time, the liquid crystal display 10
As shown in FIG. 6, it is assumed that the document data input via the keyboard 3 or the document data read from the floppy disk via the floppy disk drive device FD is displayed together with the cursor 15 as shown in FIG. As will be described later, the first display screen 12 displayed on the upper side of the liquid crystal display 10 is the non-current screen, the second display screen 13 displayed on the lower side is the current screen, and the document data to be opened later is the current screen. It shall be displayed on a certain second display screen 13.

FIG. 3 shows a flow chart of the two-division display processing program. First, the menu key 8 is operated to change the display to the two-division display screen, and "File" is selected from the displayed main menu. Next, "Fi
From the “le” submenu, select “Open File fo”
r Dual ”. By these operations, FIG.
As shown in FIG. 2, the liquid crystal display 10 includes a first display screen 12 and a second display screen 13 at the position of the cursor 15.
The screen is switched to the split display screen (S1). At this time the first
The coordinate position of the screen frame lower side 14 of the display screen 12 is stored in the first coordinate position storage area 32, and the coordinate position of the screen frame upper side of the second display screen 13 is stored in the second coordinate position storage area 33 (S10). .

In this embodiment, as shown in FIG. 7, when the two-split display screen is opened, the second display screen 13 is always the current screen, and the first display screen 12 is not the current screen (S11: NO). The screen frame of the display screen 12 is displayed by a thin line, and the screen frame of the second display screen 13 is displayed by a thick line (S13). Here, if the first display screen 12 is the current screen (S11: YES), the screen frame of the first display screen 12 is displayed by a thick line and the screen frame of the second display screen 13 is displayed by a thin line as shown in FIG. It is displayed (S12).

When a key input is made in S14 (S1
4: YES) Proceeding to S15, if the input key is the current screen switching key 5 (S15: YES), the current screen and the non-current screen are switched (S16).
After that, the process returns to S12. If no key input is made in S14 (S14: NO), the process stands by. For example, when the current screen switching key is input in the state shown in FIG. 7, the current screen switches from the second display screen to the first display screen (S1
6), the first display screen 12 becomes the current screen (S
11: YES), based on the coordinate position data stored in the first coordinate position storage area 32 and the second coordinate position storage area 33, as shown in FIG. The screen frame of the display screen 13 is displayed as a thin line (S
12).

If the subsequently input key is not the current screen switching key 5 (S15: NO) but the screen size setting key 6 (S17: YES), the screen size setting process described later is performed (S19). After that, the process returns to S12. If the key is not the screen size setting key 6 (S17: NO), the process corresponding to each key is performed (S18). Next, S1
Regarding the control of the screen size setting process performed in FIG.
This will be described with reference to the flowchart of FIG.

FIG. 4 is a flowchart of the screen size setting processing program. If the first display screen 12 is not the current screen (S20: NO), the value of the second coordinate position storage area 33 is taken out (S21). On the other hand, if the first display screen 12 is the current screen (S20: YES), the first
The value in the coordinate position storage area 32 is extracted (S22). The value of the extracted second coordinate position storage area 33 or the value of the first coordinate position storage area 32 is set to the dashed coordinate position storage area 3
4 (S23), and the broken line 16 is displayed at the coordinate position as shown in FIG. 9 (S24).

Next, if the key operated by key input (S26: YES) is the cursor up / down moving key 4 (S2
7: YES) The value of the broken line coordinate position storage area 34 is stored in the broken line coordinate position moving storage area 35 (S28), and the value of this broken line coordinate position moving storage area 35 is set in accordance with the pressing of the cursor up / down moving key 4. If the addition / subtraction value has reached the limit (S30: YES), the value of the broken line coordinate position storage area 34 is stored in the storage area 35 for moving the broken line coordinate position (S31), and an error is generated. A warning sound for notifying is issued (S32). If no key is input (S26: NO), the process stands by.

Here, a method of judging the limit of addition and subtraction will be described. The upper limit value and the lower limit value of the number of rows that can be added and subtracted are stored in advance in the addition and subtraction limit value memory 25 of the ROM 21. Then, when the value in the broken line coordinate position moving storage area 35, which temporarily stores the coordinate position when the broken line 16 moves, exceeds the addition / subtraction limit value, it is determined that the addition / subtraction is the limit. Then, when the value of addition and subtraction is the limit (S3
0: YES, S31), and also when the value of addition and subtraction is not the limit (S30: NO), the broken line coordinate position storage area 3
The broken line of the coordinate position stored in 4 is deleted (S3
3) The data saved in the broken line lower screen save area 36 is returned to the coordinate position of the broken line coordinate position storage area 34 (S34), and the value of the broken line coordinate position moving storage area 35 is set in the broken line coordinate position storage area 34. S after memorizing (S35)
Return to 24.

By repeating the above steps, as shown in FIG. 10, a broken line 16 for setting the current screen size is set.
Can be moved up and down while displaying a section. In S27, if the operated key is not the cursor up / down moving key 4 (S27: NO), the operated key is the current screen size determination key 7 (S36: YE).
S), the current screen size determination process described later is started (S37). On the other hand, if it is not the current screen size determination key 7 (S36: NO), the process corresponding to each key is performed (S38) to set the current screen size. After finishing the process, S
Return to 12.

Next, the current screen size determination process performed in S37 will be described with reference to FIG. Figure 5
It is a flowchart of the current screen size determination processing program, and when the current screen size determination processing (S37) is started, the broken line 16 of the coordinate position stored in the broken line coordinate position storage area 34 is erased (S40). Here, it is assumed that the difference between the coordinate positions of the screen frame lower side 14 of the first display screen 12 and the screen frame upper side of the second display screen 13 is fixed to X. X is the thick line width of the screen frame that indicates that the screen is the current screen.

Next, if the first display screen 12 is the current screen (S41: YES), the broken line coordinate position storage area 3 is displayed.
The value of 4 is stored in the first coordinate position storage area 32 (S4
2) The value of the coordinate position obtained by adding X to the value of the first coordinate position storage area 32 is stored in the second coordinate position storage area 33 (S43). If the first display screen 12 is not the current screen (S41: NO), the value of the broken line coordinate position storage area 34 is stored in the second coordinate position storage area 33 (S44), and the value of the second coordinate position storage area 33 is calculated from the value. The value of the coordinate position obtained by subtracting X is stored in the first coordinate position storage area 32 (S4
5). Therefore, the thick line in the two-divided display screen is always displayed by expanding the line width by X in the direction of the non-current screen with reference to the lower side or the upper side of the screen frame of the current screen, and the screen size of the current screen varies. There is nothing to do.

With the above, the current screen size determination process ends, and the process returns to S12 in FIG. 3 and if the first display screen 12 is the current screen (S12: YES), the first coordinate position storage area 32 and the second coordinate position storage area are stored. At the coordinate position of the area 33, the screen frame of the first display screen 12 is displayed as a thick line with a line width X, and the screen frame of the second display screen 13 is displayed as a thin line (S13). If the second display screen 13 is the current screen. (S12: NO), first coordinate position storage area 32 and second coordinate position storage area 3
At the coordinate position of 3, the screen frame of the first display screen 12 is displayed as a thin line, and the screen frame of the second display screen 13 is displayed as a thick line with a line width X (S1
4) Do.

For example, consider a case where the first display screen 12 is the current screen. Since the first display screen is the current screen, the screen frame is displayed with a thick line as shown in FIG. Next, the screen frame lower side 14 of the screen frame of the first display screen 12 changes to a broken line 16 as shown in FIG. When the up / down cursor up / down key 4 is operated, the broken line 16 moves up, and when the down cursor up / down key 4 is operated, the broken line 16 moves down as shown in FIG. When the current screen size determination key 7 is operated when an appropriate size of the current screen is obtained, the broken line 16 changes to the same thick line as the screen frame of the first display screen, which is the current screen, as shown in FIG. As described above, the size of the current screen is determined, and then the document data is edited.

As shown in the above embodiment, when a document is edited on the two-division display screen, the screen frame of the current screen is displayed with a thick line and the screen frame of the non-current screen is displayed with a thin line, so that it can be seen even during the editing work. Thus, the current screen can be identified, and it is possible to avoid erroneously destroying the document data in the non-current screen even after repeating the switching operation between the current screen and the non-current screen. Also, when setting the size of the current screen, by displaying the lower or upper side of the screen frame of the current screen with a broken line, it is possible to accurately grasp the size to set the current screen, and to display the non-current screen to be referenced. You can set the size of the current screen without obscuring it.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and various modifications and improvements can be made without departing from the spirit of the present invention. It can be easily guessed. For example, in the present embodiment, it is assumed that the current screen is displayed on the second display screen 13 without fail when the two-division display screen is opened, but the current screen may be displayed on the first display screen. Further, regarding the display means of the division area line, in the present embodiment,
The current screen has a thick frame line, the non-current screen has a thin frame line, and the broken line is used as a division line when setting the size of the current screen, but the current screen has a thin frame line and the non-current screen has a thick frame line. May be used. Further, it may be a boundary line that simply separates the current screen and the non-current screen without using a frame.

In this embodiment, the two-divided screen is divided into rows (vertical direction), but it may be divided into columns (horizontal direction). Further, in this embodiment, a current screen switching key 5, a current screen size setting key 6, and a current screen size determination key 7 of the menu key 8 are provided, and a series of two-division display screen processing is executed by operating these. But
Any operation method may be used as long as it is possible to operate the two-division display screen processing in the above embodiment.

[0031]

As is apparent from the above description, the document processing apparatus according to the present invention changes the position of the first division area line of the edit screen while setting the position of dividing the display screen into two. The divided area line changing means for displaying the first divided area line in a third display manner different from the first display manner and the second display manner, and the third by the divided area line change means
The display screen is divided into two because it is provided with an edit screen setting means for setting the area of the edit screen by the first division area line displayed in the display manner and then switching the display manner of the first division area line to the first display manner. In doing so, it is possible to reduce an error in setting the two-divided position.

Further, since the first division area line of the edit screen and the second division area line of the reference screen are displayed in the first display mode and the second display mode which are different from each other, the division area line display means is provided. The non-current screen can be easily identified, and the erroneous operation such as the destruction of the reference data due to the erroneous recognition of the current screen and the non-current screen can be reduced.
(EN) The operability of a document processing device at the time of editing a document using a split display screen is improved to enable smooth document editing.
