Abstract

PURPOSE:To easily move a ruled line to an arbitrary position by providing a ruled line data storing means, ruled line movement control means and ruled line data reloading means. CONSTITUTION:A cursor moving key 10c moves a cursor mark to the head position of the ruled line to be moved and an area designation key 10b is pushed. Further, the cursor moving key 10c moves the cursor mark to the end position of the ruled line to be moved and the area designation key 10b is pushed. Thus, the movement of the ruled line is set over a range from the head position to the end position. Next, by pushing a ruled line moving key 10a, the movement of the ruled line is commanded. Therefore, by moving the cursor mark by the cursor moving key 10a afterwards, the ruled line data of a ruled line memory 16 is reloaded with the movement of the cursor mark and the ruled line in a display picture is moved as well.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ruled line processing device, and more particularly to a ruled line processing device used for creating a frame v'j, that is, a ruled line, in a text editing device such as a so-called word processor.

In text editing devices such as word processors,
Framing, i.e., adding rules and lines when creating sentences
- Often required.

FIG. 1 is a diagram showing ruled lines displayed on a display of a text editing device or the like. In FIG. 1, there are cases where it is desired to move ruled line 1 shown as a solid line to, for example, ruled line 2 shown as a dotted line. In such a case, in the conventional ruled line processing apparatus, it was necessary to erase the data for ruled line 1 and then input the data for ruled line 2. The operation for inputting the ruled line data varies depending on how the ruled line data is processed or stored, but it generally requires very complicated operations, takes a long time, and is troublesome.

For example, when storing ruled line data corresponding to each character display position on a display, the ruled line data must be input one character at a time. Furthermore, when storing the ruled line data as coordinate data on the display screen of the gold display, it is necessary to determine the coordinates of the ruled line to be created in advance and input the determined coordinates, for example, in the form of a mathematical formula. The former method is based on the patent application No. 56-4088 already filed by the applicant of this invention.
6 is shown in detail.

Therefore, the main object of the present invention is to provide a ruled line processing device that can easily move all already inputted ruled lines to any arbitrary position without requiring complicated operations as in the prior art.

Another object of the present invention is to arbitrarily select a desired ruled line and move the selected ruled line to an arbitrary position without moving it with other ruled lines.

In summary, the present invention provides a ruled line data storage means for storing all ruled line data necessary for displaying ruled lines on a display device independently of display data for other display contents, and ruled lines to be moved. A device comprising ruled line movement control means for specifying all the specified ruled lines and moving the specified ruled lines, and data rewriting means for rewriting the ruled line data stored in the ruled line data storage means as the specified ruled lines are moved. It is.

The above objects and other objects and features of the present invention will become more apparent from the following detailed description with reference to the drawings.

The text memory I3 and the ruled line memory 1G each store character data and ruled line data corresponding to the character display position of the display image of the display device 14.

FIG. 3 is an illustrative diagram for explaining all the ruled line data used in the embodiment of FIG. 2. As shown in FIG. 3, an area surrounded by, for example, 24 bits in the vertical direction and 24 pits in the horizontal direction is defined as a character pattern recording area for one character. A vertical line 31. above in FIG. 3 from the center of this recording area. A plurality of ruled line patterns are determined by combinations of the lower vertical line 33, the right horizontal line 34, and the left horizontal line 32.

For example, the ruled line at address (10,2) in FIG. 4 is formed by a combination of horizontal line 34 and vertical line 33 in FIG. For example, a 4-pit code is assigned in advance to these plurality of ruled line patterns. Then, the ruled line memory 16 stores a code indicating a ruled line pattern corresponding to the character data storage address of the text memory 13 according to the character display position of the display image of the display device 14.

Furthermore, the editing control circuit 12 includes an X buffer 22, a Y buffer 28 . A counter 24 is connected to.

This X buffer 22 stores the number of characters in the X-axis direction (see FIG. 1), that is, the number of columns of sentences, included in the range when setting the range in which the ruled line is to be moved.

Further, when setting the range in which the ruled line is to be moved, the Y buffer 23 stores the number of characters in the Y-axis direction (see FIG. 1) included in the range, that is, the number of lines of text.

In addition, when shifting the ruled line data, the K counter 24
This is used as an address pointer indicating which line the currently shifted ruled line data is.

Furthermore, the edit control circuit 12 includes an address circuit 17 and an address pointer (hereinafter simply referred to as a pointer) Pl,
P2. Pa is connected. Pointer P1. P2. P3 includes an X counter and a Y counter, respectively, and is used to store the start address and end address of the range in which the ruled line is to be moved, and to store data for address control when moving the ruled line. These pointers PI, P2 . The output of P3 is given to address circuit 17. This address circuit 1

The R7 display stand and printing device 15 include, for example, a dot printer. These devices 14 and 15 combine data from the text memory 13 and the ruled line memory 16 and display or print the combined data.

Here, referring again to FIG. 1, key operations in the embodiment shown in FIG. 2 will be explained. First, use the cursor movement key 10c to move the cursor mark to the starting position (for example, AI) of the ruled line to be moved, and press the area designation key tobt-. Furthermore, the user moves the cursor mark to the last position (for example, Bl) of the ruled line to be moved using the cursor movement key 10c, and presses the area designation key 10b'. As a result, the movement of ruled lines in the range of 81 from AI is set. Next, the ruled line movement key 10ai is pressed. This commands the movement of the ruled line. Therefore, if the cursor mark is subsequently moved using the cursor movement key 10c, the ruled line data in the ruled line memory 16 is rewritten accordingly, and the ruled lines in the displayed image are also moved. For example, when the cursor is moved to the position of the cursor mark 'tAlO by the cursor movement key 10c after the ruled line movement key 10a is pressed, the ruled line l shown by the solid line is moved to the position of the ruled line 2 shown by the dotted line. Note that in this embodiment, it is also possible to specify a part of the ruled line and move it to an arbitrary position. For example, if the area from A2 to B1 of the ruled line 1 indicated by the solid line is designated to be moved and moved to the position of the cursor mark 1A20, the ruled line indicated by the dotted line will be moved. In this case, there is a space between A2 and A20, but if you input the rule m+later, the entire 11 ruled lines will be extended in the X-axis direction.

FIG. 4 is an illustrative diagram for explaining the entire operation of the embodiment of FIG. 2. 5, 6A, 6B, 6C, and 6D are flowcharts for explaining the operation of the embodiment of FIG. 2. The operation of the embodiment shown in FIG. 2 will be described below with reference to FIGS. 4 to 6D.

First, the cursor mark is moved to the beginning position of the ruled line to be moved using the cursor movement key 10c. Therefore, the steps shown in FIG. 5 (abbreviated as S in the diagram) ■,
After step 2, press cursor movement key 10 in step 3.
It is determined that c is suppressed, and in step 4, the X counter and Y counter of the cursor counter 21 are incremented and decremented in accordance with the movement of the cursor mark. Next, in step 5, it is determined whether the flag F2 included in the editing control circuit 12 is set. At this time, since flag F2 is not set, the operation in step 1 is performed again.

Next, the area designation key 10b is pressed to set the starting position of the range to which the ruled line is to be moved.

Then, in step 1, it is determined whether the area designation key 10b (7) has been pressed. Then, in step 6, it is determined whether the flag F1 is set.

At this time, since the flag F1 is not set, the contents of the cursor counter 21, that is, the address of the starting position of the ruled line to be moved, is transferred to the pointer P3 in step 7. Then, in step 8, flag F1 is set. Note that when the area designation key 10b is pressed, a specific number or symbol (for example, A) is displayed in the cursor mark, and it is recognized that the area designation is the start position designation.

Next, the cursor movement key 10c is operated again, and the cursor mark is moved to the last position of the ruled line to be moved. Therefore, in step 3, it is determined that the cursor movement key 10c has been pressed, and the operations in steps 4 and 5 are performed. Next, the area designation key tab is pressed again, and the last position of the ruled line to be moved is set. At this time, since the flag F1 was set in step 8, all operations in step 9 are performed after the determination in step 6. In step 9, the contents of the cursor counter 21, that is, the address of the last position of the ruled line to be moved, is transferred to the pointer P2. Then, in step 10, the flag F1 is reset. Note that by pressing the area designation key 10b for the second time, a number or symbol different from the above-mentioned specific number or symbol (for example, B
) is displayed. This recognizes that the area specification at that time is the specification of the last position of the ruled line to be moved.

The above operation completes the designation of the area in which the ruled line is to be moved, and next, the ruled line movement key 10a is pressed to move the ruled line. This is determined in step 2. and,
In step 11, the count value of the X counter of pointer P2 is subtracted from the count value of the X counter of pointer P3,
Address difference in the X-axis direction of the movement specified area, that is, the number of characters included in the range of the ruled line to be moved (see Figure 4)
is calculated and written to the X buffer 22. Further, in step 12, the count value of the Y counter of pointer P2 is subtracted from the count value of the Y counter of pointer P3, and Y
The axial address difference, that is, the number Y of lines included in the range of the ruled line to be moved (see FIG. 4) is calculated and written to the Y buffer 23. Then, in step 13, flag F2 is set.

Next, the cursor mark is moved to move the entire ruled line by operating the cursor movement key 10c. That is, in step 3 it is determined whether the cursor movement key 10c is depressed, and after the operation in step 4, in step 5 it is determined whether the flag F2 is set. And step 14
At this point, the contents of the pointer P3, that is, the start address of the ruled line movement designated area, are transferred to the pointer PI. Thereafter, in steps 15.16 and 17 the direction of movement of the cursor mark is determined. Depending on the determination of the moving direction, the ruled line moving operation shown in FIGS. 6A to 6D is performed.

First, with reference to FIG. 6A, a case will be described in which the cursor mark and therefore the rule M are moved to the right on the screen in FIG. 1 or 4. In this case, step 18
At this point, the count value of the X counter of pointer P1 is incremented by 10I and transferred to pointer P2. That is, in FIG. 4, when pointer P1 specifies address 1 (10, 1), pointer P2 specifies address (10, 2)' at a position shifted by one character in the X-axis direction. Next, in step 19, the contents of the Y buffer 23, that is, the number of lines included in the designated movement range of the ruled line, are transferred to the counter 24. Then, in step 20, the ruled line data for X characters in the same line starting from the position indicated by pointer P1 in the ruled line memory 16 is shifted so that the starting position is at the position indicated by pointer P2. That is, the ruled line data of the first line within the designated movement range is shifted rightward by one character. Next, in step 21, the ruled line data at the position indicated by the pointer P1 in the ruled line memory 16 is cleared. Then, in step 22, the Y counter of the pointer P1 is incremented by one. That is, pointer P1 specifies the address (11,1) on the 11th line in FIG. 4. Next, step 2
3, the X counter of pointer P1 is i+11. and transfers it to pointer P2. In other words, pointer P2 is address (11,2)! It will be shown. In this way, preparations for shifting the next row of ruled line data are made in steps 22 and 28. Next, in step 27, the counter 2
4 is incremented by -l, and in step 25 it is determined whether the count value of the counter 24 is O. That is, in step 25, it is determined whether the ruled line data of the line shifted in step 20 is the ruled line data of the last line of the designated movement range. If the count value of the X counter is not 0, the operations of steps 20 to 24 are repeated.

In this way, the ruled line data of each line is shifted to the right by one character, and the ruled lines in the specified range are moved to the right. When the row is shifted to the last row, the count value of the X counter 24 becomes 0, and in step 26, the X counter of the pointer P3 is incremented by 1. In other words, the first position of the ruled line is (10,2)
The pointer P3 memorizes the movement.

Next, the operation for moving the cursor mark and therefore the ruled line to the left will be described with reference to FIG. 6B. Since the operation in this case is almost the same as the operation in FIG. 6A, only the different portions of the operation will be explained. That is, in step 27 corresponding to step 18, ll1
1 X counter ff1-I of pointer P1 and pointer P
Transfer to 2.

Therefore, pointer P2 stores address (10,0). Also, step 3 corresponding to step 23 above
In step 2, the X'6 counter of pointer P1 is decremented by 1 and transferred to pointer P2. Further, in step 35 corresponding to step 26, the X counter of pointer P3 is decremented by 1 and the leading position of the ruled line after the movement is stored.

Next, the operation when moving the cursor mark and therefore the ruled line downward in FIGS. 3 and 4 will be described with reference to FIG. 6C. In this case, in step 36, the contents of the Y buffer 123, that is, the number of rows in the Y-axis direction of the designated movement range are added to the Y counter of the pointer P1.

Therefore, pointer PI stores address (n, 1).

Then, in step 37, the Y counter of pointer P1 is incremented by 1 and transferred to pointer P2. Therefore, pointer P2 stores address (n+1.1) at this time. Thereafter, in step 38, the contents of the Y buffer 23 are transferred to the counter 24. Next, in step 89, the same operation as in step 20 or 29 is performed. Then, in step 40, the contents of pointer P1 are transferred to pointer P2. Furthermore, in step 41, the Y counter of pointer P1 is decremented by 1.

That is, in steps 40 and 41, preparations are made for shifting the next row. Next, in step 42, the counter 24 is decremented by 1, and in step 43, it is determined whether the count value of the counter 24 is O. The determination in step 43 is the same as step 25, and the operations in steps 39 to 42 are repeated until the ruled line data in the last row of the designated movement range is shifted.

When the shift of the last line of the specified movement range is completed, in step 44, the ruled line data for X characters on the same line is cleared from the position corresponding to the pointer PIK in the ruled line memory 16. Then, in step 45, the pointer P3
The Y counter of is incremented by 1, and the starting position of the ruled line after the movement is stored.

Next, referring to K, 6D (2), the operation when moving the cursor mark in the entire direction above the ruled line will be explained. Since the operation in this case is almost the same as the operation in FIG. 6C, only the different parts will be fully explained. First, when moving the ruled line upward, the operation corresponding to step 36 is not necessary. This is because when moving a ruled line downward, it must be shifted sequentially from the last row of ruled line data in the specified movement range, but when moving it upward, it must start from the ruled line data on the first line of the specified movement range. This is because it is sufficient to shift them sequentially. Next, step 37
In step 46 corresponding to , the Y counter of pointer P1 is decremented by 1 and transferred to pointer P2. Therefore, pointer P2 stores address (9, 1) at this time.

Further, in step 50 corresponding to step 41, the Y counter of pointer P1 is incremented by 1. Further, in step 54 corresponding to step 45, Y of pointer P3 is
The counter is incremented by 1 and the entire starting position of the ruled line after the movement is memorized.

As described above, the ruled line can be moved in accordance with the moving direction of the cursor mark. In addition, when moving the ruled line in an oblique direction as shown in FIG. 1, the cursor mark may be moved by a predetermined amount to the right or left and then moved downward or upward by a predetermined amount.

If it is determined in step 55 of FIG. 5 that another function key is to be suppressed after the movement of the ruled line is completed, the flag F2 is reset in step 56, and the subsequent operation of the cursor movement key 10c simply moves the cursor mark. It only gives instructions.

Generally, when creating text, characters are entered in a format such as A4 size or B5 size, but if the ruled lines are moved too much, they may extend beyond this size. It is also possible to determine whether the size of the format has been exceeded, and if the size has been exceeded, to disable all operations and issue a warning to the operator.

Furthermore, as described above, there are methods of processing and storing ruled line data other than those used in this embodiment, such as storing the coordinates of ruled lines in the form of mathematical formulas, and the present invention is not limited to such methods. Other ruled line data processing methods can also be applied to storage methods.

As described above, according to the present invention, the ruled line data is rewritten as the ruled line moves, thereby making it possible to easily move the ruled line to any desired position without requiring complicated operations as in the past. Moreover, it is possible to specify a desired ruled line and move only the specified ruled line regardless of other ruled lines, thereby further improving operability in changing the layout of frames, etc.
