Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] This IJI relates to a data output device for hard copying a multi-window screen.

[Prior Art] Conventionally, in office computers and the like, when a hard copy key is operated while a multi-window is displayed on a CRT screen, the multi-window screen is printed out as is. In other words, the contents of multiple window screens are hard-copied in an overlapping state.

Therefore, as shown in Figure 6 (A), if you hard copy a multi-window in which window screens B and C overlap behind the window screen A of the highest song,
As shown in FIG. 6(D), only a portion of the contents of window screens B and C were printed.

Therefore, if you want to print all the contents of window screens B and C, switch the window screens so that window screens B and C appear immediately before them, as shown in Figure 6 (B) and (C). I was trying to make a hard copy from there. FIGS. 6(E) and 6(F) show examples of printing when hard copying is performed with the window screen switched as described above.

[Problems to be Solved by the Invention] However, in order to switch and display each of the overlapping window screens to the front, it is necessary to perform switching operations a number of times in accordance with the overlapping.

Especially if there are a large number of overlapping windows,
This method has the disadvantage that the number of operations is extremely large, making it troublesome.

An object of this invention is to print out the display information of the rear screen without performing a screen switching operation even when making a hard copy of the screen behind the multiple screens that are displayed in a superimposed manner. It has been made possible.

[Means to solve the problem] The means of this invention are as follows.

Screen information storage means l (see the functional block diagram in Fig. 1,
The same applies hereafter) is a window screen RAM etc. that stores display information for a plurality of logical screens.

The display means 2 is a CRT display device or the like that displays and outputs overlap information (multi-window information) in which the display information for the logical plurality of screens is superimposed.

The print control means 3 is a display copying device or the like that responds to a specific print command and reads display information stored in the one-screen information storage means 1 one screen at a time and prints it out. Here, the print control means 3 sequentially reads display information for a plurality of screens stored in the screen information storage means 1 and prints out the information, or prints out the display information stored in the screen information storage means 1, or
Print out the display information for the screen.

[Work] The operation of the means of this invention is as follows.

Currently, in a state in which overlap information obtained by superimposing display information for multiple screens is displayed, that is, in a state in which a multi-window screen is displayed, the screen information storage means 1 displays the information displayed on the display means 2. Display information for multiple screens is stored.

In this state, when making a hard copy of the multi-window screen, by operating a predetermined key, etc., the print control means 3 reads out the display information stored in the screen information storage means 1 for each screen individually and prints it out. let

Therefore, even when making a hard copy of the screen behind a plurality of screens displayed in a superimposed manner, the display information of the screen behind the screen can be printed out without performing a single screen switching operation.

[Example] Hereinafter, an example will be described with reference to flIJ2 to FIG. 5.

FIG. 2 is a system configuration diagram of the data output device.

The CPU II controls various operations of this data output device according to microprograms stored in the ROM 12. When it receives a multi-window display command from the keyboard 13, etc., the CPU II
14 and the data input from the keyboard 13 are imported into the RAM 15 for the window 9 screen.
write to.

The window screen RAM 15 stores display information for multiple screens constituting a multi-window screen sequentially for each screen, that is, for each window, in the order in which they are stacked. Creates overlap information that overlaps display information for the screen and stores it in video RAM (VRAM) 16.
write to.

The video signal synthesis device fi17 reads out the contents of the video RAM 16, converts it into a video signal, and converts it into a video signal from the CRT display device i18.
If the overlap information is written in the video RAM 16 in a normal configuration where the display is output from the CRT
A multi-window screen is displayed on the display device 18.

The display copying device 19 uses a hard copy key 〇〇P and a window copy key WCP provided on the keyboard 13.
When the key is operated, the video R
The contents of the AM 16 or the contents of the window screen RAM 15 and video RAM 16 are read out, converted into print signals, and printed out by a printer 20 constituted by a thermal printer, a liquid crystal printer, or the like. here,
The hard copy key HCP is a key that instructs the display copy device 19 to print only the contents of the video RAM 16, and the window copy key WCP instructs the display copy device 19 to print the contents of the RAM 15 for the window 9 screen and the video RAM 1B. This key instructs you to print.

The display copying device 19 also includes a hard copy key HCP,
CPUUI in response to window copy key WCP operation
Gives a CPU stop signal to I. In addition, this CPU
The stop signal is a signal that remains at a high level from when the hard copy key HCP or window copy key WCP is operated until the printing operation is completed.While this signal is at a high level, CPUII performs window screen operations from time to time. R.A.
The data write operation to M15 is temporarily stopped.

Next, the operation of this embodiment will be explained with reference to f:IS 3 to 5.

It is now assumed that a multi-window screen as shown in FIG. 3 is displayed on the CRT display W11B.

In this case, each window and screen ■,
Overlap information is written in which the images 1 and 2 are superimposed, and display information corresponding to each of the window screens 2, 2, and 3 is sequentially written in the window screen RAM 15.

Here, when the display copying device 19 is powered on, it starts executing operations according to the flowchart in FIG. state (steps S1, S2).

Now, assuming that the hard copy key HCP is operated, the display copying device 19 operates as follows.

That is, when the depression of the hard copy key HCP is detected in step S1, the two-display copying device 19 turns on the CPU stop signal (step S3).

As a result, the CPU stop signal becomes a high level signal, and when this signal is input to the CPU II, the CPU II stops writing data to the window screen RAM 15. After stopping the writing operation of the CPU II in this way, the display copying device 19 transfers the data to the video RAM.
16 is read out and printed out from the printer 20 (step S7). As a result, the contents of the multi-window screen shown in FIG. 3 are printed out as they are (f
JS5 (see figure (A))), and after printing the contents of the video RAM 16, the display copying device 2119 turns off the CPU stop signal (step S8).
The PU stop signal becomes low level, and the CPU II resumes writing data to the window and screen RAM 15.

Then, the display copying device 2219 enters the state of waiting for key input again (steps S1 and S2).

Further, when the window copy key WCP is operated, the display copying device 19 operates as follows.

That is, when detecting that the window copy key WCP is pressed in step S2, the display copying device fi19 first turns on the CPU stop signal as in the case described above (step S4).
), and the contents of the window screen RAM 15 are read out and printed out from the printer 2°, but in this case,
Among the display information for multiple screens stored in the window screen RAM 15, display information for one bottom surface from the top is read out and printed out (step s5). As a result, in the multi-window 9 screen shown in FIG. , first,
The contents of the window screen ■ displayed immediately before that are printed out (see No. 51.;d (B)).

When the printing for 9 windows of l is completed in this way, the process proceeds to the next step S6, and it is checked whether all the windows have been printed. Since there is, the process returns to step S5 and the display information for the next screen is retrieved from the window screen RAM 15.
That is, the contents of the window screen ■ are read out and printed out (see Fig. 5 (C)), and the process returns to step S5 again, and the contents of the window screen ■ are read out from the window screen RAM 15 and printed out (see Fig. 5 (C)). (See (D)).

When all the windows 9 have been printed in this way, the process proceeds to step S7, where the contents of the video RAM 16 are printed out (see FIG. 5(A)), and in the next step S8, the
After turning off the PU stop signal, the process returns to step S1.

In this way, in this embodiment, the hard copy key HC
When P is operated, the contents of the multi-window screen are simply printed as is, as usual, but when the window copy key WCP is operated, the contents of the multi-window screen are printed in addition to the multi-window screen. Since the contents of each window screen are sequentially printed out, it is possible to make a hard copy of each window screen without complicated operations.

Also, when you operate the window copy key WCP, C
Since the writing operation of the PUII is stopped and the contents of each window screen at that time are copied, it is important to completely preserve the momentary screen information of a certain problem when managing computer usage.

In the above embodiment, the contents of each window screen are printed sequentially, but by providing a specifying means for arbitrarily specifying a window screen, the contents of the specified window screen may be selectively printed. good.

In addition, a window screen buffer (having a capacity that can store the contents of the window screen RAMI 5) is provided in the display copying device a19, and under the control of the CPU II, the stored contents of the window screen RAM 15 are transferred to the window screen buffer 5. The content of each window screen may be transferred and printed under the control of the display copying device 19.

[Effects of the Invention] This invention makes it possible to print out the display information of the rear screen without performing a screen switching operation even when making a hard copy of the screen behind the multiple screens that are displayed in a superimposed manner. Therefore, it is possible to efficiently make a hard copy of the window screen.
