Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a document creation device that can edit documents in units of editing areas, and in particular, to control display/hide of documents within an area. related to display control technology.

(Prior Art) Generally, in a document creation device (word processor), in order to improve its document creation function and document editing function, characters, figures, ruled lines, etc. can be created within the same document. Furthermore, recently, images such as illustrations and photographs can be input using image scanners, etc., as necessary.
It is configured so that the input image can be displayed on the screen together with the document.

In order to display an image on the screen, first, the display position of the image is determined by a cursor operation or the like. In this case, since the document is displayed on the screen, if the screen is scrolled for positioning operation, it is necessary to follow the scrolling and redeploy the document data into the display buffer.

For this reason, there is no problem when positioning the image within the range of one display screen, but when positioning it outside of one display screen, screen scrolling is required, so the document data is replayed along with the scrolling. Because expansion processing is performed, it takes a long time from when scrolling is specified until the screen is actually scrolled.

This becomes a major factor in reducing the efficiency of editing processing using images.

In addition, in terms of operability, documents include not only characters but also figures and ruled lines as mentioned above, so if such a document and an image are displayed together on the screen, the image will be distorted. There are problems such as making it difficult to recognize visually.

In this way, conventionally, various functions are executed on a display screen with document data displayed, and there is a problem in that editing efficiency and operability are degraded depending on the functions to be executed.

(Problem to be Solved by the Invention) Conventionally, various functions are executed on the display screen with document data displayed, so depending on the function to be executed, editing efficiency and operability may be reduced. was there.

This invention was made in view of these points, and it is possible to automatically switch between displaying and hiding a document according to the content of the function executed on the display screen, so that it is always displayed regardless of the function executed. It is an object of the present invention to provide a document creation device that can obtain sufficient editing efficiency and operational performance.

[Configuration of the Invention (Means and Effects for Solving the Problems) The present invention provides a document creation device having a layout editing function that allows a plurality of editing areas to be arbitrarily set on a display screen. means for holding display management information indicating whether or not to display the document in the editing area above; means for controlling display of the document in the editing area according to the display management information; and a display screen for editing the layout. and means for rewriting the display management information so that the document in the editing area is controlled to be hidden during the execution period of the predetermined function in response to the execution command operation of the predetermined function. do.

In this document creation device, display management information is rewritten in response to an execution instruction operation for a predetermined function. Therefore, the display/non-display of the document is automatically switched when the execution of the function is specified, and the document can be hidden during the execution period of the function. Therefore, no matter what function is executed on the display screen, automatic switching between display and non-display of documents makes it possible to always obtain sufficient editing efficiency and operational performance.

The input unit 41 performs various functions on the layout editing display screen where the print image of the document in the editing area is displayed, such as image calling, printing, display switching, correcting the size of the editing area, connecting areas, etc. Specify the execution of the function. Here, area concatenation is a function that assigns the distribution order for distributing the document to other areas when the amount of created documents is too large to fit in one area. It's about. In addition, the display switching function includes setting the display size on the layout editing display screen, setting whether to display the scale for that display screen, and setting the display within the area (whether to display everything or only the frame of the area). ), setting whether to display external characters, setting optional fonts (switching between displaying in Mincho or options), and setting image display (switching whether to display images on the screen) Contains the following features:

The process of specifying such various functions by the input unit 41 is performed in the first
This is performed on the message data and setting screen output from the display control section 29 and displayed on the display section 43 shown in the figure.

Further, when the display switching function is specified by the input section 41, a setting screen as shown in FIG. 3 is displayed on the display section 43 by the message data and display control section 29.

The display management information switching unit 42 performs overall control such as correcting and concatenating the size of the editing area, printing documents in the area, etc. according to the contents selected and specified on the screen by the input unit 41, and also controls the display format management table. The display management information stored in 21c is rewritten. This rewriting is performed on the information regarding the setting of display within an area in the display management information mentioned above, and is performed when a specific function (for example, image, area connection, etc.) is specified in the input section 41. In response to this, the management information for display within the area is changed from "display all" to "display only frame".

The display form management table 21c includes display management information selected on the setting screen for display switching shown in FIG.
That is, management information (data such as flags) regarding display size, scale display, area display, external character display, option font, and image display is stored.

The display control unit 30 controls the display of the layout editing display screen according to the display management information stored in the display format management table 21e, and when the management information for display within the area is set to "display all" In this step, the print control device 19 is instructed to display the document within the area. In this case, the print control device 19 displays the document within the area and the area frame on the display unit 43.

M2g is combined with the area frame image from the display control device 20 and displayed on the liquid crystal display 30.

On the other hand, if the management information for display within the area in the display form management table 21c is set to "display only frame", the display control device 30 instructs the print control device 19 to hide the document within the area. In this case, since the print control device 19 does not develop the document data into the print image buffer 27, only the area frame is displayed on the screen.

Next, the document display changing operation by the display control system shown in FIG. 2 will be described with reference to the flowchart in FIG. 4.

Here, as an initial state, the display form management table 21
Assume that the intra-area display management information of e is set to "display all".

In this case, on the layout editing screen of the display unit 43,
A frame indicating the area and the document within the frame are displayed.

In this state, various functions are specified by the user's key operations, but certain functions, such as the image function (
When the display management information switching unit 42 recognizes and determines that the area concatenation function (F1) or the area connection function (F2) has been specified (step Al), the display management information switching unit 42
reads the management information for display within the area from the display format management table 21e, saves it to the work buffer inside the display management information switching unit 42, and also sets the management information for display within the region in the display format management table 21e to "All". "display" to "display only frame" (step A2). Then, the display control unit 20 clears the print image of the document data developed in the print image buffer 27 by controlling the print control device 19 according to the management information of "display only the frame", thereby clearing the print image of the document data in the area. is hidden, and only the frame of the area is displayed on the layout editing screen of the display unit 43 (step A3).

After this, the image function (Fl) or region concatenation function (
The process of F2) is executed on the layout editing screen (step A4), and the process is completed (including execution cancellation).
When it is recognized and determined (step A5), the display management information switching unit 42 restores the saved management information of the display within the area to the display form management table 21c, that is, changes the initially set "display all" (Step A)
S).

The display control unit 20 then controls the display format management table 21.
The print image of the document data is developed in the print image buffer 27 by controlling the print control device 19 according to the "display all" management information stored in c. They are also displayed on the layout editing screen of the display section 43 (step A7).

As explained above, in the document creation device of this embodiment, predetermined functions (image, region connection, etc.) by the user are provided.
The display management information is rewritten in response to the execution command operation. Therefore, the display/non-display of the document is automatically switched when the execution of the function is specified, and the document can be hidden during the execution period of the function.

When the document is controlled to be hidden, even if the screen is scrolled by the user's cursor operation, there is no need to re-deploy the document data to the print image buffer 27, so the scrolling process can be performed at high speed. can.

Therefore, in this embodiment, no matter what function is executed on the display screen, the display screen can always be maintained in an easy-to-operate state by automatically switching between displaying and hiding documents. This makes it possible to obtain high editing efficiency and operational performance.
