DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram showing a schematic configuration of a document editing system according to one embodiment of the present invention. This document editing system performs various document editing processes with a control device 1 composed of a CPU that controls the entire apparatus as a core. The control device 1 includes an input device 2 having a keyboard and a mouse, a ROM, A storage device 3 having a RAM or the like and using a hard disk, a floppy disk, or the like as a recording medium
And the output device 4 are connected. The output device 4 is connected to a display device 5 and a printer (not shown). The control device 1 responds to various editing commands similarly input from the input device 2 with respect to document element data such as characters and symbols input from the input device 2 in accordance with a program preset in the ROM of the storage device 3. In response, various editing processes including a character string format setting process to be described later are performed, and the edited document data is temporarily stored in the RAM of the storage device 3 and is also stored in the hard disk of the storage device 3. 5 to control display and printing by a printer. When performing such editing processing, the control device 1 sends the R in the storage device 3 to use for a specific purpose.
The area prepared in AM is adopted.

Next, the contents of the character string format setting process controlled by the controller 1 of FIG. 1 will be described with reference to FIG.

FIG. 2 is a diagram showing a display image of a character string from the designation of the character string range of the document to the drawing of the intersection ruled line.

On the display screen of the display device 5, a character string of one line is displayed horizontally, and a ruled line in the character string (FIGS. 2 and 1) is provided with an intersection ruled line for "do not destroy". And

In the initial state of the display screen of FIG. 2, the character insertion point is located after the character "i" (FIGS. 2 and 1).

The character insertion point is moved so as to designate the front of the character "" by operating the keyboard or mouse of the input device 2 (FIGS. 2 and 2). Next, the character insertion point is moved from “を” to “I” by the input device 2 to specify a rectangular area from “領域” to “I”. The designated range information is temporarily stored in the RAM of the storage device 3, and the range designation is completed (FIGS. 2 and 3).

In this state, an instruction to set a cross ruled line is input by the input device 2. As a result, the control device 1 obtains the first coordinates (Xs, Ys) of the start position and the first coordinates (Xe, Ye) of the end position of the specified range from the specified range information stored in the storage device 3, and The height t of the line within the specified range is calculated (FIGS. 2, 6), and the calculated coordinate information and the height of the line are stored in the storage device 3.

The control device 1 calculates the first coordinates (Xs, Ys) of the start position of the designated range calculated and stored and the first coordinates (Xs, Ys) of the end position.
Based on the coordinates (Xe, Ye) and the height t of the line, a process of drawing a line segment on the diagonal line of the designated area is performed (FIGS. 2, 4 and 5).

Next, a description will be given of a processing procedure from the above-described designation of the range of the character string to the application of the intersection ruled line to the area of the designated range with reference to FIG. FIG. 3 is a frame illustrating a processing procedure for applying a cross rule to a character string according to the present embodiment.

First, in step S1, a character string range designation operation is performed. That is, for example, assuming that the character insertion point is next to the character "i" as shown in FIGS. 2 and 1 above, the character insertion point is changed from this state to the character " ”(FIGS. 2 and 2), and then again after the character“ I ”to specify a range, a rectangular area in the specified range is woven (FIGS. 2 and 3). This specified range information is temporarily stored in the storage device 3.

When this range designating operation is completed, a command for setting a cross ruled line is executed by operating the input device 2 in step S2. With this command, the control device 1 calculates the first coordinates (Xs, Ys) of the start position of the specified range from the specified range information stored in the storage device 3 (step S).
3), and first coordinates (Xe, Ye) of the end position of the specified range
Is calculated (step S4), and the coordinate information is stored in the storage device 3.

Next, the control device 1 controls the first Y coordinate Ys of the start position of the designated range calculated and stored and the first Y coordinate Ys of the end position.
Then, it is determined whether the designated range extends from one line or a plurality of lines (step S5). When both Y coordinates (Ys, Ye) are the same, that is, when the designated range is one line, the control device 1 determines the height t of the line within the designated range from the designated range information in the storage device 3. Calculate (Step S
6), and store the calculation result in the storage device 3.

Since all the information of the rectangular area for which the range has been specified has been prepared by the above processing, the control device 1 performs a process of drawing a line segment on the diagonal line of the rectangular area of the specified range based on the information at step S7. And S8.

First, a display command corresponding to the display device 5 is output to the output device 4, and the first coordinates (Xs, Ys) of the start position are output.
Of the end position obtained by subtracting the line height t from the Y coordinate of
A line segment is drawn along the diagonal of the rectangular area up to the coordinates (Xe, Ye-t) (step S7). Then, from the Y coordinate, the row height t
A line segment is drawn in the same manner as described above from the second coordinate (Xs, Ys-t) of the start position after subtracting the minute to the first coordinate (Xe, Ye) of the end position. As a result, a diagonal line segment, that is, an intersection ruled line is drawn in the rectangular area in the specified range.

On the other hand, when the first Y coordinate Ys at the start position of the specified range is different from the first Y coordinate Ye at the end position in step S5, that is, when the specified range extends over a plurality of lines, Then, a process of drawing a diagonal line segment for each line within the specified range is performed.

That is, first, the control device 1 regards the start position of the specified range as the current position from the specified range information in the storage device 3, and stores the position in the storage device 3 (step S9). Next, the height t of the line to which the character at the current position belongs is calculated (step S10). Further, the end position of the line (hereinafter referred to as line end position) is obtained from the specified range information in the storage device 3 (step S11), and the obtained line end position and the end position of the specified range of the specified range information in the storage device 3 are obtained. Are compared (step S12). If the end of the line is later than the end of the specified range by this comparison, that is, if the specified range ends at the line, the coordinates of the current position (Xs, Ys)
And the coordinates (Xe, Ye) of the end position of the designated range are calculated, and a line segment is drawn based on these coordinates and the row height t in the same manner as described above (step S13). That is, the display command is output to the output device 4 up to the second coordinate (Xe, Ye-t) of the end position obtained by subtracting t minutes from the Y coordinate of the first coordinate (Xs, Ys) of the start position of the designated range. And draw a line segment. Next, in the same manner, a line segment is drawn from the second coordinate (Xs, Ys-t) at the start position obtained by subtracting t minutes from the Y coordinate to the first coordinate (Xe, Ye) at the end position, and designated by this. This means that the intersection ruled line has been drawn up to the end position of the range area.

On the other hand, if it is determined in step S12 that the end of the line is not after the end of the designated range, that is, if the designated range does not end at the current line and continues to the next line, the coordinates (Xs, Xs, Ys) is calculated, the coordinates (Xe, Ye) at the end position (end of line) of the specified range are calculated, and a line segment is drawn based on these coordinates and the height t of the line. That is, the coordinates (Xe, Ye-t) of the end position (current position) obtained by subtracting t minutes from the Y coordinate of the start position (current position) of the specified range (Xs, Ys).
The display command is output to the output device 4 until a line segment is drawn (step S15). Next, similarly, the coordinates (Xs, Ys-) of the start position (current position) obtained by subtracting t minutes from the Y coordinate are similarly calculated.
A line segment is drawn from (t) to the coordinates (Xe, Ye) of the end position (end of line) (step S16), whereby a cross rule is drawn from the current position to the end of line.

Next, the control device 1 obtains the start position of the next line from the specified range information stored in the storage device 3 in order to proceed to the processing of the next line (step S17). Is set as the current position (step S18). And
Step S10 and subsequent steps are executed again, and the processing up to the line where the specified range ends is continued.
