BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation device that can set the size and position of characters on a character-by-character basis, and more particularly to a document creation device that is characterized by character overwriting processing.

0002

2. Description of the Related Art Various developments have been made in document creation devices such as Japanese word processors to further improve operability and functionality. One of these is the expansion of character modification functions.

For example, conventionally, when a character B is overwritten on a character A, the character A is erased. That is, on the document buffer, character A is erased and character B is inserted in its place.

When such conventional overwrite processing is applied to a document creation device that has a function that allows character sizes and positions to be arbitrarily set on a character-by-character basis, for example, a 1/4 double-width character A is replaced with a 1/4 double-width character A. When the character B of is overwritten, 1
/The display section of the quadruple-width overwritten character A except for the display section of the quadruple-width overwritten character B becomes blank, and most of the quadruple-width display section is displayed as a blank area.

[0005] Such a document display form goes against the expansion of character modification functions, resulting in unfavorable results in terms of functionality.

[0006]

[Problems to be Solved by the Invention] As mentioned above, conventional document creation devices that have the function of arbitrarily setting the size and position of characters on a character-by-character basis do not have the existing overwrite processing function. When this happens, a document display format with a poor amount of information may occur, with most of the overwritten portion being a blank area, which is contrary to the aim of expanding the character modification function.

[0007] The present invention was made in view of the above circumstances.
It is an object of the present invention to provide a document creation device that has a function that allows the size and position of characters to be arbitrarily set on a character-by-character basis, and which has an expanded overwrite processing function and realizes a highly versatile character modification function. purpose.

[0008]

[Means for Solving the Problems] The present invention detects overlapping characters in a document creation device in which the size and position of characters can be set on a character-by-character basis, and at the time of detecting the overlap between the overwritten character A and the overwritten character. When it is determined that the overwritten character B is smaller than the overwritten character A by comparing the sizes of B, the overwritten character A is displayed in the display area of the overwritten character A, excluding the display area of the overwritten character B. It is characterized by having a structure having means.

[0009] Furthermore, the present invention is characterized in that it has a structure that allows a document in this form to be saved.

0010

[Operation] When the overwritten character B is smaller than the overwritten character A, the overwritten character B is displayed in a part of the display section of the overwritten character A, and the overwritten character B is displayed in the display section of the overwritten character A. The overwritten character A excluding the display section portion of the character B is displayed.

[0011] In this way, by leaving the original character (overwritten character) in a draft state in the area that would conventionally be erased and left blank, the overwrite processing function is expanded and the character modification function is rich in variety. can be realized.

[0012] Furthermore, by saving, reading, and reproducing documents in this form, it is possible to create documents with greater variety.

FIG. 3 is an explanatory diagram of the operation according to an embodiment of the present invention, in which the overwrite processing routine (XRT) is followed.
This is realized by executing the overwrite process shown in FIG. Here, the quadruple-width character "Ima" corresponds to the overwritten character A, and the character "日" overwritten there corresponds to the overwritten character B.

FIG. 3(a) shows a display example when the double-width character "Ima" is overwritten with the full-width character "日", and FIG. 3(b) shows the double-width character "Ima". Figure 3 shows an example of the display when the 1/4 double-width character "日" is overwritten.
(c) shows a display example in which the double-height character "日" is overwritten on the double-width character "ima".

The operation of one embodiment of the present invention will now be described with reference to FIGS. 1 to 3.

At system start-up, the program stored in the hard disk drive 13 is loaded into the program storage area of the RAM 11 under the control of the CPU 10. At this time, the program loaded into RAM 11 includes:
An overwrite processing routine (XRT) for executing the overwrite processing shown in FIG. 1 is included.

In the input mode, the block cursor indicates the character input position, and is initially set to full-width size.

Here, by operating the function key for selecting the size of the block cursor provided on the keyboard 15, the full-width size (default) is selected.
Change the size of the block cursor to 1/4 x horizontal, 1
It can be arbitrarily selected and changed to /2-width, double-width, double-height, quadruple-width, etc., and can be moved in units of dots by operating the cursor keys. At this time, if the size of the block cursor indicating the character input position is changed to, for example, double-width, the input character becomes a double-width character.

[0031] When using the block cursor to overwrite, for example, a smaller character at a position where a quadruple-width character has been input, the overwritten character is erased and the display section of the overwritten character excluding the overwritten character is displayed. However, in the present invention, as shown in FIG. 3, by the overwriting process shown in FIG. Except for the overwritten character ``Ima'', it is displayed as a draft.

That is, the presence or absence of character overlap (overwrite) is determined (step S1 in FIG. 1), and if there is character overlap, the size of overwritten character A and overwritten character B is determined by the magnification of each character. A comparative judgment is made based on the attributes (step S2 in FIG. 1).

Here, if the overwritten character A is smaller than or equal to the overwritten character B, the normal overwriting process similar to the conventional one is executed (step S3 in FIG. 1).

When overwritten character A is larger than overwritten character B, overwritten character B is displayed in a part of the display section of overwritten character A, and overwritten character B is displayed in the display section of overwritten character A. The overwritten character A excluding the display area is displayed (steps S4 to S7 in FIG. 1).

That is, first, the overwritten character A is saved in the save area 11b in the RAM 11 (step S4 in FIG. 1), and then the overwritten character B is written into the document buffer (step S5 in FIG. 1). When writing the overwritten character B into the document buffer, attribute information indicating that the overwritten character A is attached to the overwritten character B is added.

[0036] Then, the save area 11b in the RAM 11
Read the overwritten character A saved in the video RAM (
V-RAM) 19 (step S6 in FIG. 1), and the overwritten character B is also expanded in the video RAM 19 (FIG. 1).
Step S7).

As a result, the overwritten character B is displayed in a part of the display section of the overwritten character A, and the overwritten character A excluding the display section of the overwritten character B is displayed in the display section of the overwritten character A. is displayed.

A concrete example of this display is shown in FIG.

Here, the quadruple-width character "Ima" corresponds to the overwritten character A, and the overwritten character "日" corresponds to the overwritten character B.

FIG. 3(a) shows an example of a display when the double-width character ``day'' is overwritten with the double-width character ``day''.

[0041] FIG. 3(b) shows the quadruple-width character "now" and 1/
A display example is shown when the quadruple-width characters "日" are overwritten.

FIG. 3(c) shows an example of a display in which the double-height character "日" is overwritten on the double-width character "ima".

In this way, when the overwritten character B is smaller than the overwritten character A, the overwritten character B is displayed in a part of the display area of the overwritten character A, and the overwritten character A
By displaying the overwritten character A excluding the display area of the overwritten character B, the original character (overwritten character) can be written in a draft state in the area that would normally be erased and left blank. This allows a wide variety of character modification functions to be realized.

In the above embodiment, since the character size can be specified arbitrarily and the block cursor can be moved arbitrarily in units of dots, the above-mentioned overwriting process can be performed not only within the same line column position but also across line columns. Of course, there are cases in which this is executed.

[0045]

Effects of the Invention As detailed above, according to the present invention, in a document creation device in which the size and position of characters can be set on a character-by-character basis, there is provided a means for detecting overlapping characters, and a method for detecting overlapping characters. means for comparing the sizes of overwritten character A and overwritten character B; and when it is determined by this means that overwritten character B is smaller than overwritten character A, a display section for overwritten character B is displayed in a display section for overwritten character A; By having a configuration including a means for displaying the overwritten character A with the part removed, the original character (overwritten character) can be written in a draft state in the part that would conventionally be erased and left blank. The overwrite processing function can be expanded to realize a wide variety of character modification functions.
