Description

Detailed Description of the Invention Technical Field The present invention relates to a display device having a multi-window display function suitable for use in various data processing devices such as personal computers, office computers, word processors, and DPS (data processing systems).
The present invention relates to an improvement in a printing device, and particularly to a display/printing device that can obtain a hard copy of each virtual screen memory through an operation similar to a conventional hard copy operation of a real screen memory.

Specifically, since the priority is low, the virtual screen memory that is behind the window display can be selected, so that a hard copy of the desired screen can be executed, and it can be used regardless of the currently running program. The present invention relates to a display/printing device that enables efficient use of multi-window display and simplification of hard copy operations by quickly performing back-end processing.

2. Description of the Related Art Conventionally, display devices having a multi-window display function, so-called multi-window display systems, have been used in various data processing devices.

Multi-window display uses CR, which is a physical display device.
This is a display method in which the display screen of a display device such as T is divided into an arbitrary number of sections and separate data is displayed in each section.

FIG. 6 is a diagram showing an example of the correspondence between a virtual screen and a real screen in a conventional display/printing device having a multi-window display function. In the drawings, virtual screen 1 is a first virtual screen memory, virtual screen 2 is a second virtual screen memory, real screen is a real screen memory, and F indicates a folder (outer frame).

In FIG. 6, multi-window display is performed by displaying an arbitrary part of the data contents of the two virtual screens 1 and 2 on the left in each section of the real screen shown on the right. .

In this way, the display device having the multi-window display function allows multiple windows to be opened on the real screen.

Therefore, this multi-window display is extremely convenient when processing a plurality of mutually related jobs in parallel.

In the case of a multi-window display system, each section of the real screen display screen in FIG.

Only one window (in this display example, virtual screen 2 surrounded by folder F) allows input and processing for that window.

Activate this window (AC DIVE)
Other windows are simply displayed and cannot be used for input or other processing. Folder F is usually displayed in reverse video so that it can be easily distinguished from other areas. It is being

By the way, in a conventional display/printing device having a multi-window display function, that is, a display/printing device equipped with a multi-window display system and a hard copy function,
When creating a hard copy from screen data using the hard copy function, the printer is configured so that only the data displayed on the actual screen can be output to the printer.

For example, when a plurality of windows are displayed as shown on the right side of FIG. 6 as a real screen, only a hard copy similar to the display state of the real screen is obtained.

In the case of FIG. 6, the portion of the virtual screen 2 surrounded by the broken line and the portion of the virtual screen 10 pie chart are copied at the same time.

Therefore, when many windows overlap,
You will end up with a hard copy that is very difficult to read.

Therefore, in order to obtain an easy-to-read copy, it is recommended to select the required screen from the overlapping real screens as shown in Figure 6, change it to the same size as the real screen, and then create a hard copy. required.

Besides, when you need to copy the shaded window area,
For example, in FIG. 6, the part of the virtual screen 2 outside the broken line,
When it is necessary to copy an area that is not displayed on the real screen, such as the left part of the virtual screen 1, the desired area is copied after switching windows.

In any case, the conventional display/printing apparatus having a multi-window display function has the disadvantage that the operator is forced to perform extremely inefficient work.

Purpose Therefore, the present invention solves these disadvantages in conventional multi-window display systems having a hard copy function, namely, that only the data displayed on the real screen can be printed, and furthermore, it is possible to print data that is displayed on a specific virtual screen memory. By solving the inconvenience of having to perform complicated operations to print data, and by simply selecting the desired screen, the data in each virtual screen memory can be printed, thereby increasing the multi-window display function. The object of the present invention is to make effective use of a data processing system to which a display/printing device is connected and to simplify temporary copying operations.

Specifically, by making it possible to quickly obtain not only real screen data but also hard copies of each virtual screen with a simple operation, display and printing devices can be used effectively. The purpose is to simplify hard copy temporary operations.

In the display/printing device of the present invention, hard copy selection information is inputted through the input device 1 comprising a keyboard or the like, and provided by programs stored in the first to nth program sections 3a to 3n, respectively. is possible.

First, a case will be described in which hard copy selection information is input from the input device 1 such as a keyboard.

FIG. 3 is a flowchart showing the flow of processing when a hard copy is selected from the input device in the display/printing device having the multi-window display function of the present invention shown in FIG.

In the following explanation, in order to facilitate understanding, FIG. 6 and FIG. FIG. 7 showing an example of a hard copy according to the above will be used as an example.

In addition, the screen number of the actual screen is "0", 1st to nth
The screen numbers of the virtual screens are "1" to r, respectively.
In nJ, screen No. of virtual screen l.

It is assumed that the screen number of the virtual screen 2 is "1" and the screen number of the virtual screen 2 is "2".

When the hard copy execution key is pressed, the flow shown in FIG. 3 starts, and the system waits for screen selection input.

In this state, select the screen you want to make a hard copy of. As already explained, in the examples of FIGS. 2 and 6, the screen number is "0" for the real screen, and the first to nth virtual screens are numbered rlJ to rnJ, respectively. There is.

The number pressed after the hard copy execution key is screen N.
o, the hard copy screen number is saved in the save area 91, this screen number is given to the screen selection section 92, and the screen corresponding to the screen number is selected.

When a screen is selected, the screen read section 93 reads the image data of the selected screen.

The read data is converted by the printer output data creation section 94 into data for output to the printer, and is output to the printer 10.

This process creates a hard copy of the selected screen.

For example, when 1 screen number "0" is selected, the data of the actual screen shown in the display example of FIG. 6 is read out and a hard copy like the actual screen shown in FIG. can get.

Further, when the screen number "1" is selected, the data of the virtual screen 1 shown in FIG. 6 is read out, and a hard copy like the virtual screen 1 shown in FIG. 7 is obtained.

Similarly, when the screen number "2" is selected, the data of the virtual screen 2 in FIG. 6 is read out, and a hard copy like the virtual screen 2 in FIG. 7 is obtained.

Next, a case where hard copy is executed within a program, that is, a case where hard copy selection information is provided by programs stored in the first to nth program sections 3a to 3n, respectively, will be described.

FIG. 4 is a flowchart showing the flow of processing when a hard copy is selected by a program in the display/printing device having the multi-window display function of the present invention shown in FIG.

Here, as an example, it is assumed that program A and program B are being executed.

FIG. 5 is a diagram showing a program A in a display/printing device having a multi-window display function according to the present invention.

As shown in Figure 5, program A creates a graph from input data, executes a hard copy after the graph creation is completed, and then creates the next graph. Suppose it is a program.

It is also assumed that program B is a program for inputting data.

In program A, as shown in FIG. 5, a function is prepared for the hard copy, and the screen number is passed as an argument to the function.

In this case, the screen number (Screen No. 01) is the same as in the previous case, with the real screen being numbered "0" and the first to nth virtual screens being numbered "1" to "n", respectively. It is assumed that there is

By writing the program as shown in FIG. 5, it is possible to execute the process of creating and displaying a graph and then making a hard copy.

That is, when a hard copy is specified from the key, the fourth
The diagram flow starts, the arguments are checked, and the keyboard processing routine begins.

Next, the hard copy function is called using the input numeric key as an argument.

Next, a screen is selected using this argument.

The subsequent processing is similar to the case using the input device described above, in which data is read from the selected screen, printer output data is created, and a hard copy is obtained.

For example, when the screen number "1" is selected, the data of the virtual screen 1 in FIG. 6 is read out, and a hard copy like the virtual screen 1 in FIG. 7 is obtained.

In this way, in the display/printing device of the present invention, it is also possible to select the screen by a program.
In this case, in multi-processing, it is possible to create a hard copy of a desired screen by back-processing, regardless of the processing by the program currently being executed, so that the multi-window display system can be used effectively.

As explained in detail above, the present invention includes a real screen memory that stores display data of a physical display device, at least one virtual screen memory, and data in a partial area of the virtual screen memory is retrieved. a display/printing device having a multi-window display function and a hard copy function; A screen specifying means for specifying the real screen memory and the virtual screen memory, a screen information storage means for storing information of the specified screen, and a reading means for reading image data from the corresponding screen based on the screen information. and printer output data creation means for creating printer output data from the read data, and by designating the screen with the screen designation means, a hard copy of each screen can be selected.

auxiliary-m=( Therefore, according to the display/printing device having a multi-window display function of the present invention, even a screen displayed in a multi-window can be used in the same way as creating a hard copy of an actual screen, which has been done in the past. With the operation, it is possible to create a hard copy of the overlapping backside virtual screen.

In other words, there is no need for the conventional complicated operations in which the operator selects a window, changes its size, moves its position, etc., and then makes a hard copy.

Furthermore, since a virtual screen can be specified by the program, it is also possible to use the hard copy creation process as a background process in multi-processing, regardless of the process currently being executed, which makes multi-window display effective. The advantage is that the use and creation of a hard copy of the virtual screen is significantly simplified.
