Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device capable of displaying a plurality of windows.

[Conventional technology]

Conventional display devices capable of displaying multiple windows on a display screen display various messages and image information in each window to diversify the display contents.

[Problem to be solved by the invention]

However, in this type of conventional display device, when an operator wants to exchange the window located on the left and the window located on the right on the display screen, the operator has to perform the following instruction operation.

That is, the display screen must be temporarily erased, and the type and position of a new window to be displayed must be specified. For example, if five windows are displayed and the operator wants to exchange the display positions of two of them, the operator must respecify all the windows to be displayed, so the operator has to perform complicated instructions when changing the window display. Conventional display devices have some drawbacks.

Therefore, it is an object of the present invention to solve such problems and to provide a solution when changing the display position of two or more windows.
An object of the present invention is to provide a display device that can reduce an operator's instruction operation effort.

(Means for Solving the Problems) In order to achieve such an object, the present invention provides a storage means for storing output information to be displayed in a plurality of window display areas on a display screen for each window screen; an input means for inputting instructions for mutually exchanging display positions of output information displayed in a plurality of window display areas, and a display screen for output information stored in the storage means in response to instructions inputted manually from the input means Display control means for exchanging and setting display start addresses of the above windows with each other, and display means for displaying output information of the storage means based on the display start addresses exchanged by the display control means. shall be.

The present invention also provides a storage means for storing output information to be displayed in a plurality of window areas whose display positions on a display screen are predetermined in correspondence with the display positions of each window, and A manual means for inputting an instruction command to mutually exchange the display positions of the displayed output information, and a start of writing of the output information stored in the storage means and each window of the storage means in response to the instruction input from the input means. It is characterized by comprising an information processing means for exchanging and setting addresses, and a display means for displaying output information of the storage means exchanged by the information processing means.

(Function) In the first embodiment of the present invention, when the operator instructs replacement of the window to be replaced using the input means, the display control means exchanges the display start address of the window with respect to the stored information in the storage means. So the window display on the display screen is automatically replaced.

Furthermore, the operator only has to issue an instruction to replace the window, making the instruction processing by the operator much easier than in the conventional example in which the operator issues an instruction to display all windows.

In the second embodiment of the present invention, the output information of the storage means is exchanged in response to the window exchange instruction of the input means, and the write address for the output information of each window of the storage means is exchanged. It is possible to exchange window displays, and there is no need to change the preset window display start address.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 2 shows a specific circuit configuration of an embodiment of the present invention.

In Fig. 2, 1 is a central processing unit (cpυ) that controls the entire device connected to the common bus, and executes the control procedure shown in Fig. 4 to perform window exchange processing. functions as display control means and information processing means.

2 is an information input keyboard connected to the common bus. The keyboard 2 as an input means has a cursor key 2-
11 position instruction key 2-2 and window replacement instruction key 2-3 are provided.

The cursor key 2-1 is a key for inputting the direction and amount of movement of the cursor mark displayed on the display screen of the display unit 9, and is used to specify the window on the display screen.
The position instruction key 2-2 is a key for instructing the display 9 to output information on the cursor position on the display screen set by the cursor key 2-1. Although this example describes an example in which the coordinate position is input using the cursor key 2-1, it is also possible to use a dedicated coordinate input device called a mouse.

2-3 is a window exchange instruction key for instructing exchange of two window displays specified by cursor key 2=1.

In response to pressing the window replacement instruction key 2-3, CPt
11 starts the finder exchange process.

Memories 3 to 7 are readable and writable by the CPt1l, and are provided for each type of stored information.

The (work) memory 3 stores general data related to arithmetic processing of the CPUI.

Memories 4 to 6 store information to be displayed in the first to third windows, respectively, on a double-sided basis. Memory 4~
6 functions as a storage means.

The memo leaf constitutes two parts of the display means, and stores display image information in the form of dots in correspondence with the display position of the information to be displayed on the display 9. For example, character information is processed in the form of a character code for external information processing. When the apparatus is manually operated, the character code signal is converted into dot information indicating a character image by a character generator (not shown), and is stored in the bitmap memory 7.

A driving circuit 8 drives the display 9 based on display information stored in the bitmap memory.

In this example, OM^(
Direct memory access) controller! 0 reads the information to be displayed from the bitmap memory 8;
11 is an interface that receives information to be displayed from an external information processing device.

The window exchange process of this embodiment in such a configuration will be explained with reference to the flowchart of FIG. 4. In this example, it is assumed that the display positions of the first to third windows are determined in advance.

FIG. 4 shows a control procedure executed by CPt1l shown in FIG.

In FIG. 4, upon receiving window display information and a display window instruction via the interface 11, the CPUI stores the display information in the window memory corresponding to the designated window (step S1).

For example, information to be displayed in the first and second windows as shown in FIG. 3(^) is stored in the memory 4.5 for the first and second windows.

Next, the CPU converts the display information of the two windows into dot-shaped display information and writes it into the bitmap memory 7 in correspondence with the display position of each window (step S2).

The display information stored in the bitmap memory 7 is D.
The signal M^ is sent to the drive circuit 8 according to an instruction from the controller IO, and is displayed as an image on the display 9.

Since the control processing up to this point is conventional processing, the explanation will be kept brief.

In this state, when the operator uses the cursor keys 2-1 (see Figure 2) to move the cursor to the first window on the display screen and presses the position instruction key 2-2, the A cursor counter (not shown) provided in the cursor counter (not shown) transmits cursor position information to the CPUI. CPIII
When the cursor position information is received, it is identified that the cursor is within the preset first window area based on the cursor position, and the number "1" of the window to be replaced is stored in the work memory 3 ( Step 53-1).

Next, the operator selects the second window by pressing the cursor key 2.
-1 When specified by the position instruction key 2-2, CPIJI stores the window number "2" in the work memory 3 in the same procedure as described above (step S6 → 53 → 54-5
4-1).

Next, when the operator presses the window exchange instruction key 2-3, (:PIll confirms that the number of windows stored in the work memory 3 is 2, and selects the window "1" for the bitmap memory. and the writing start address of "2", that is, the display start address are exchanged. When the CPU reads the display information from the first window memory 4 corresponding to this window number "1",
Subsequently, the read display information is sequentially written in the bitmap memory 7 starting from the position corresponding to the first window after the write address positions have been exchanged.

When the writing of the display information in the first window memory 4 is completed, the CPUI subsequently transfers the display information in the second window memory 5 to the corresponding area of the second window in the bitmap memory 7 (step Sa).

As a result, the window display on the display screen of the display device 9 is changed from the display shown in FIG. 3(^) to that shown in FIG. 3(B).

Next, as shown in Figure 5 (^), the first to
A case will be described in which the displays A to C in the third window are exchanged.

In Figure 5 (^), for example, the first window A and the third
When replacing window C, install the first window on the rear side to be replaced.
An area in the bitmap memory 7 of the non-overlapping portion of window A is determined in advance, and only the display information corresponding to the display position of the third window memory 6 is written in this area. Needless to say, the display information of No. 4 is exchanged with the display information of the current third window in the bitmap memory 7.

As explained above, in this embodiment, the bitmap memory 7 for display and the memories 4 to 6 for storing display information in each window are provided, and the bitmap memory By exchanging the information of each window stored in 7 using CPIII, the window display is automatically exchanged on the display screen.

Further, even if the window screen is replaced, the information stored in each window memory 4 to 6 remains unchanged, so that replacement display can be performed any number of times.

In this embodiment, the display start address of the display screen, that is, the memory address of the bitmap memory 7 is exchanged to exchange the display information of the window in the bitmap memory 7, but each window memory In a display device that directly reads and displays data from windows 4 to 6 in accordance with the display position of the window, as a second embodiment of the present invention, memory for each window 4 to 6 is read out in response to a window replacement instruction from an operator. All you have to do is replace it with the write start address for each memory of the stored contents and information received from the outside.
In this case, after the contents of each window memory 4 to 6 are temporarily stored in the work memory 3, the contents of the work memory are rewritten to the corresponding memory by CPIJI.

Since the display control means exchanges the display start address of the window with respect to the stored information, the window display on the display screen is automatically exchanged. Furthermore, the operator only has to issue an instruction to replace the window, making the instruction processing by the operator much easier than in the conventional example in which the operator issues an instruction to display all windows.

As yet another method, in the second embodiment of the present invention, the output information of the storage means is exchanged in response to a window replacement instruction of the manual means, and the write address for the output information for each window of the storage means is exchanged. This makes it possible to exchange window displays and eliminates the need to change the preset window display start address.

〔Effect of the invention〕

As explained above, according to the present invention, the first aspect of the present invention
In this case, if the operator instructs the replacement of the window to be replaced using the input means, the storage means
