BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing device capable of moving/copying and editing the contents of documents displayed at different display magnifications.

0002

2. Description of the Related Art Conventionally, in image display devices used in word processors, workstations, personal computers, etc., the display magnification of documents is collectively managed. Therefore, when images are displayed on a display screen, they are displayed at a uniform magnification. That is, the image is displayed at a specified display magnification among several preset display magnifications. At that time, even if you switch to window display mode, the display magnification in each window will be the same as the screen before this window was opened (
That is, the display magnification of the background screen of the window is automatically set. As a result, all window images and their background images are displayed at the same display magnification.

0003

[Problems to be Solved by the Invention] As described above, in the display magnification setting method for conventional image display devices, the display magnification of a plurality of windows displayed on one display screen is selected from a plurality of predetermined display magnifications. The display magnification is uniformly set to one selected from the following. Usually, when using the word processors, workstations, personal computers, etc. mentioned above, it becomes necessary to edit documents, rearrange data, etc. In this case, for example, the source figure or data can be displayed locally in an enlarged window to search for the cutting point, while the destination text or data can be displayed in a reduced window and the insertion point can be checked while checking the overall layout. The task of making a decision is necessary. However, as mentioned above, in the conventional display magnification setting method, the display magnification of each window displayed at the same time is uniformly set to the selected display magnification. The display magnification of figures and data cannot be changed.

[0004] Therefore, when editing a document using a conventional image display device, the area around the cutout point in the source document is displayed at a high display magnification, and the cutout point (for example, a figure) is determined. The figure cut out at this determined location is temporarily stored in the working memory. Next, the text near the cut-out figure insertion point in the destination document is displayed in a reduced size at a low display magnification, the move location is determined while checking the balance of the entire document, and the above-mentioned data is stored at this determined move location. You must call up the cutout shape and insert it. In other words, the source document and the destination document must be read out separately and displayed separately at a desired display magnification, making the editing process extremely troublesome. As a result, there is a problem in that the transferred figure may not be transferred to the transfer location intended by the operator in one editing process.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a document editing device that can easily perform editing processing such as moving/copying even between documents displayed at different display magnifications.
