Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a display switching method in a document processing device.In recent years, document processing devices that edit and process a sentence, figure, etc. while displaying it on a display screen have become popular. . In this type of document processing device, there is a so-called multi-window processing method in which one display screen is divided into a plurality of windows and a plurality of tasks are processed in parallel. In the case of multi-window processing, for operator operability, it is desirable to display only the window currently being processed and to prevent windows that are not subject to processing from remaining on the display screen. In order to erase a window that is not the target of the display from the display screen, it is necessary to terminate the task that owns the window, and to display the window on the display screen, the task must be started again. On the other hand, there is a method that shrinks windows that are not subject to processing and leaves them on the display screen, but this requires space, and it is difficult to secure this space especially when the number of windows increases by two or three. It was difficult.

[Purpose of the invention]

In the multi-window processing of nine document processing devices, the present invention temporarily erases windows that are not the target of processing from the display screen without terminating the task, and instantly redisplays them when needed. It is an object of the present invention to provide a display switching method that can effectively utilize the space on a display screen.

[Structure of the invention]

EMBODIMENT OF THE INVENTION Below, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a document processing apparatus according to the present invention. In FIG. 1, image data input from an image scanner 1 and text data input from a keyboard 2 are written into a work memory 15 via an input control section 3 and an internal bus 100. The floppy disk 4 stores processed data and unprocessed data, and the floppy disk controller 5. The data is transferred to the work memory 15 via the internal bus 100. Programs, guidance information, etc. are stored in the hard disk 6, and the programs are loaded into the program memory 14, and the guidance information, etc. are transferred to the work memory 15 via the hard disk control section 7 and the internal bus 100. The contents of the work memory 15 are transferred via the internal bus 100 1, the image data as is, and the code converted to a dot pattern by the character generator 13.
The image is transferred to the image memory 11 and displayed on the 4 display device 12.

The operator operates the pointing device (mouse) 9 while looking at the display screen of the display device 12.

As with the keyboard 2, menu instructions, task selections, etc. are input via the input control unit 10.

Processing unit I (CPU) 8 is the middle phase of the system.

The program in the program memory 14 is executed.

The programs in the program memory 14 are roughly divided into a system program that controls processing 2 of the entire system, an application program that controls user window processing, and a video program that controls display processing.

FIG. 2 shows an example of the structure of the display surface. The display screen consists of a system area, a user area, and a kana-kanji guidance area. 101 to 107 are system icons, all of which are processed by the system program.

101 means a system help request, +02 means a screen reorganization request, 103 means a system termination request, and 104 means a main menu display request. 105 is the archive name display user I/ who is remembered following this icon.
Activation request 106 of F means a activation request of the document name display editor that is remembered following this icon. Reference numeral 107 indicates a request to display the name of the activity that has the window that has been reduced to the icon following this icon, and to bring the window that has been reduced to the icon to the front of the work area. This icon 107 is related to the present invention.

The user area is divided into a window ladder and other work areas. 110 to 113 are user icons, 110 is a request for user help, 111 is a request to end this activity, 112 is a request to display the current window of the relevant window by reversing it, and 113 is a request to degenerate the relevant window to the background. .

The headers of the system area, guidance area, and user area have a fixed size, but the size of the work area changes depending on the number of user windows. FIG. 2 shows a case where only one user window is opened in the work area.

FIG. 3 shows an example of the structure of a window memory area prepared in the work memory 15 shown in FIG. This system window corresponds to the system area of the display surface in FIG. 2, the guidance window corresponds to the kana-kanji guidance area, and the user window corresponds to the user area. Here, there are three user windows, and therefore up to three user windows can be opened simultaneously on the display screen. Even if you erase a window that is not the target of processing from the display screen, its contents remain in the corresponding user window in the window memory area.
By instructing, it will be redisplayed in the user area.

The contents of the menu window are displayed in the work area at any time by pointing to the icon 104.

Figure 4 shows the processing flow from system startup to opening one user window on the display screen.
As shown in FIG. 2, the user window is displayed over the entire user area of the display surface. FIG. 5 is a process flow diagram when the second side of the user window is opened following the first side of the user window. In this case, the user area of the display screen is divided into two, and two sets of user windows are displayed.

Of the two user windows displayed on the display screen,
FIG. 6 shows a processing flow for erasing one user window that is not subject to processing on the display surface, and FIG. 7 shows a processing flow for restoring it to the display surface. That is, when a certain user window is to be deleted from the display screen, the mouse 9 is used to point to the background icon (BG fine) 113 of the corresponding user window on the display screen. As a result, the corresponding BG fine 107 in the system area of the display screen
is changed to reverse display, and the name of the job to be deleted (BG job name) is displayed in the area following the icon 107. At the same time, the user window specified with the mouse 9 is erased from the display screen. As explained above, the contents of the corresponding user window on the work memory 15 remain unchanged. To restore the erased user window to the display screen, use the mouse 9 to point to the corresponding BG fine 107 that is displayed in reverse in the system area of the display screen.

As a result, the reverse display of the corresponding BG fine 107 is restored, and the user window contents corresponding to the job name are read out from the work memory 15 and restored to the display screen.

〔Effect of the invention〕

As is clear from the above description, one aspect of the present invention is as follows.

In multi-window processing of a document processing device, user windows that are not being processed can be temporarily deleted from the display screen without terminating the task, and only the job name remains on the display screen. Effective use of display screen space and improved operability are achieved.
