Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a method for searching for a corresponding ruled line in various data processing devices (hereinafter referred to as a word processor, etc.) such as a word processor, an office computer, or a data processor. When selecting all or part of a group of ruled lines that make up a table, etc., and selecting the target ruled line to be moved or deleted, the operation method for specifying the target ruled line will be unified, and the corresponding If there is no ruled line, it is automatically processed as the first instruction of the two-point instruction, and by simply giving the next one-point instruction, the ruled lines included within the range of the diagonal instruction can be searched, and the word The present invention relates to a method for searching for a corresponding ruled line, which reduces the burden on an operator when operating ruled lines in a table or the like using a processor or the like, and improves operational efficiency.

Conventional technology Word processors and other devices are connected to CTR, plasma, and other display devices for inputting documents, tabulations, etc., and the operator inputs the necessary data while interacting with the display screen. Output processing is in progress.

In this case, particularly when manipulating ruled lines for tables and the like, it often happens that the image of the layout drawn in the operator's head does not necessarily match the actually set ruled lines. For example, the position of a table may not be appropriate, or the length of a particular column may be incorrect.
There may be cases where you want to move or delete the ruled line because it is too large or too small in relation to the characters written inside it.

The methods conventionally used in word processors and the like to search for a corresponding ruled line when moving or deleting a ruled line are broadly classified into the following five types.

The first is a method in which an operator specifies a point on a ruled line to be selected, and a ruled line including that point is searched. In this method, there are cases where the search target is limited to only one ruled line, and cases where a plurality of ruled lines are searched at the same time.

The second method is similar to the first method above, but the target ruled line must be specified at the start point or end point.

The third method is to select all ruled lines as target ruled lines.

The fourth method is to search for all ruled lines included in the range above, below, to the left, to the right of the indicated point, depending on the position and direction of the indicated point.

The fifth method is to specify two points and search for ruled lines included within the diagonal range of the two points.

Figures 1 to 7 are display examples to explain how to search for the ruled line in a conventional word processor, etc., and 1 is a movement operation when only a part of multiple tables is moved. 2 is a state in which the corresponding ruled line to be operated is selected by the first or second search method; 3 is a state in which one ruled line is selected by the first search method; 4 is a state in which the corresponding ruled line is selected by the third search method,
5 is a state in which the fourth search method is used to search for a ruled line that is above or to the left of the indicated position and has either the start point or the end point, or both. at least 1
indicates that the ruled lines within the specified range are selected. In the drawing, a, b, e to g, k, and l are horizontal ruled lines, c, d, h to j, m, and n are vertical ruled lines, P is a cursor, and a broken line indicates that the ruled line to be operated is searched. Indicates the display state when

Here, the ruled line group a shown on the left side of FIG.
The operation for moving only the central table made up of ruled lines e to j out of three tables made up of lines e to n to the state shown on the right side of FIG. 1 will be described.

First, the operations for moving the six ruled lines e to j described with reference to FIG. 1 using the first or second search method are shown in FIGS. 2 and 3.

That is, in the method of selecting two horizontal ruled lines and two vertical ruled lines by one instruction as shown in FIG. 1 and 2, a total of three operations are required. Further, according to the first search method of selecting one line at a time as shown in FIG. 1, the movement operation is completed after a total of six operations. Note that the operation for deleting only the ruled lines e to j shown on the left side of FIG. 1 is exactly the same.

Next, if the ruled lines e to j in FIG. 1 are to be deleted using the conventional third target ruled line search method,
By instructing as shown in FIG. 1, all ruled lines a to n become the target.

Therefore, when using this third method, once all the ruled lines are deleted, the necessary ruled lines a
~d and k~n must be reset.

The same goes for moving part of the ruled line. First,
After deleting all the ruled lines, it is necessary to set the ruled line at the position after the movement, and to set the ruled line again at the original position because it was deleted even though it was not moved, and this third operation is necessary. This method is not very practical when it is desired to select part of a ruled line.

In the fourth search method, when moving some ruled lines, first specify the part that includes the ruled line to be moved, move all the ruled lines included there, and then move the unnecessary ruled lines. must be moved to return it to its original position.

For example, as shown in Fig. 1, when you specify a point, a ruled line with a start point and/or an end point is selected above or to the left of it, and the specified ruled line is searched on the display screen. The display changes to a broken line to indicate that the Therefore, by appropriately repeating such instructions, the desired ruled lines are sequentially selected and moved, and the extra moved portion is returned to its original position.

The same is true for deletion; the specification shown in Figure 1, Figure 5 will also delete the parts within that range that you originally wanted to keep. It is necessary to reset the settings.

Finally, in the fifth method, you can specify the range of movement or deletion by specifying two diagonal points.
If you specify as shown in Fig. 1 6 or 7, you can select the target ruled line with just one instruction. In particular, if you specify as shown in Fig. 1 7, you can select the center ruled lines e to j.
Moving or deleting only is extremely easy.

However, in this method of diagonal indication using two points,
Even when specifying one ruled line, it is necessary to specify two points.For example, when selecting only one ruled line, compared to the first and second methods described above,
The problem is that it takes extra effort.

As described above, each of the first to fifth conventional methods for selecting the ruled line has advantages and disadvantages.

Therefore, in the conventional method of searching for the ruled line, the first to fifth methods are used in an appropriate combination.For example, the first method is used to delete a ruled line, and the fourth or fifth method is used to move it. I try to use

However, when the various ruled line selection methods are combined in this way, the operation methods for selecting the target ruled line are different depending on whether to delete or move the ruled line, so the operator must perform the operations according to each purpose. There were disadvantages in that the method had to be learned separately, which increased the burden and reduced operational efficiency.

Problems to be Solved by the Invention The present invention solves these inconveniences in various conventional ruled line selection methods, reduces the number of operations for selecting a corresponding ruled line as much as possible in ruled line operations, and eliminates/deletes ruled lines. By unifying the movement operation method, the purpose is to reduce the burden on the operator, prevent the occurrence of operational errors, and improve the operability of word processors and the like.

Means for Solving the Problems The present invention provides a word processor that includes at least a display device and an input device, displays characters, figures, etc. on the display device according to instructions from the input device, and performs input/output processing of necessary data. In a processor or the like, a ruled line information storage means for storing already set ruled line information, and information on a designated position given by operation of the input device to designate one or two points on the screen of the display device. and the ruled line information stored in the ruled line information storage means, it is determined whether a ruled line exists at the position indicated by one point, or a ruled line having a start point and/or an end point within the diagonal range indicated by two points. ruled line search means for searching for the existence of a ruled line, when a single point is specified by the input device,
When the ruled line search means searches the ruled line information stored in the ruled line information storage means and detects that the corresponding ruled line does not exist, two points are automatically awarded based on the detection information indicating that. I try to switch to searching for instructions.

Example Next, regarding the applicable ruled line search method of the present invention,
Examples thereof will be described in detail with reference to the drawings.

In the applicable ruled line search method of the present invention, when an operator specifies one point during movement or deletion processing, if that one point is on an already set ruled line, that ruled line is determined as the applicable ruled line. On the other hand, if the specified one point is not on the ruled line, specifying the next point becomes a two-point instruction, and the starting point/point is within the diagonal range specified by the two points.
A ruled line where one or both of the end points exists is determined to be the ruled line.

By adopting this method of searching for the corresponding ruled line, operations for moving/deleting one, two, or more ruled lines as the target ruled line can be unified with one or two point instructions. You will be able to do it.

FIGS. 2 1 to 6 are display examples for explaining the selection state of a ruled line by the corresponding ruled line search method of the present invention, 1 is the state before the ruled line selection operation is performed, and 2 is the state of the ruled line to be deleted by two points. 3 is the state specified to delete one ruled line, 4 is the state specified at the same time to delete two ruled lines, 5 and 6 are specified once shows the state in which one ruled line is deleted. The symbols in the drawing are the same as those in FIG. 1, and P1 and P2 indicate the position indicated by the cursor.

First, if you want to delete one horizontal ruled line e among ruled line groups a to n in FIG. 2 1, as shown in FIG. Use the cursor to indicate the position that should not be touched. When the corresponding ruled line is searched, only the display of the ruled line e changes to, for example, a broken line, and the operator can confirm that the specified ruled line has been correctly selected. Here, a key input to delete the ruled line may be given. The selection operation for moving the ruled line is exactly the same.

Next, if you want to select the two ruled lines f and i in Figure 2 1 as the ruled lines to be deleted, move the cursor to the intersection of the two ruled lines f and i, as shown in Figure 2 4. , may be selected in one instruction, or may be selected one by one as shown in FIG. 2, 5 and 6.
The same applies to the case of movement.

Furthermore, when deleting the six ruled lines e to j in FIG. 2, the method explained with respect to FIG. It is also possible to perform the deletion process by specifying two points P1 and P2 with a cursor so that the ruled lines e to j are included within the diagonal range.

That is, first, point the first point P1 with the cursor. In this state, since there is no ruled line above the point P1, the operation of the logic circuit in the processing device such as a word processor causes the operator to
prompt for the cursor position. When the operator specifies the second cursor position P2, the ruled lines e to j included in the diagonally specified range between the two cursor positions P1 and P2 are searched as applicable ruled lines, and only the ruled lines within that range are searched. , the display changes to a display that can be distinguished from other ruled lines as shown in FIG. 2. In this state, a deletion/movement instruction may be given.

The following Figure 3 shows an example of the main parts involved in processing such as setting, moving, and deleting ruled lines in a data processing device such as a word processor used when carrying out the applicable ruled line search method of the present invention. FIG. In the drawings, 1 is a display device, 2
is a cursor control unit, 3 is an operation unit, 4 is a ruled line display control unit, 5 is a ruled line control key processing input unit, 6 is a corresponding ruled line search unit, 7 is a ruled line calculation unit, 8 is a repeat ruled line generation unit, and 9 is a set ruled line Table 10 shows the corresponding ruled line table.

A brief explanation of the functions of each part is as follows.

The display device 1 displays ruled lines, characters, cursors, and other patterns.

The cursor control section 2 displays a cursor on the display device 1 based on cursor information from the operation section 3 and outputs the current cursor position to the ruled line control key input processing section 5.

The operation unit 3 is composed of a keyboard, etc., and inputs various data and control information, and also provides instructions for setting ruled lines, moving a cursor, etc.

The ruled line display control section 4 displays ruled lines on the display device 1 based on information about the starting point, end point, and line type of the ruled line provided from other sections.

The ruled line control key input processing section 5 outputs a control signal to each section according to the input signal of the ruled line control key inputted from the operation section 3, and also takes in the current cursor position given from the cursor control section 2.

The corresponding ruled line search unit 6 searches the cursor position (x1, y1)
The corresponding ruled line is sequentially compared with the set ruled line table 9 to determine which ruled line exists on which line, or which ruled line exists within the range of one set of cursor positions (x1, y1), (x2, y2). When found, it outputs to the ruled line display control unit 4 to change the display of the corresponding ruled line to a display that is easy to distinguish from other ruled lines, such as a broken line display, and stores the ruled line information in the corresponding ruled line table 10. It works like this.

When instructed to [move] a ruled line, the ruled line calculation unit 7 calculates the positions of the starting point and ending point of the ruled line in the corresponding ruled line table 10 after the movement, and only one end of the ruled line, that is, the starting point or the ending point, is to be moved. , the same calculation is performed only for the start point or end point of the movement target.

The repeat ruled line generation unit 8 calculates the pitch M and the starting point, end point, etc. of M corresponding ruled lines to be repeated based on the instruction of the number of repeated ruled lines N, and repeats the ruled lines. The M pieces of ruled line information to be performed are generated and additionally set in the set ruled line table 9.

The set ruled line table 9 stores ruled line information of all the ruled lines currently being displayed, and outputs the ruled line information in response to a request.

The corresponding ruled line table 10 temporarily stores information about existing ruled lines included in a position indicated by one or two cursor positions and ruled lines calculated and generated during ruled line operation.

Figures 4 1 to 4 are the process flow for setting ruled lines such as setting ruled lines in Figure 3, 1 is the flow for setting the whole part and the ruled line, 2 is the move/delete operation, and the corresponding ruled line is found by specifying one point. Processing flow when
3 is a process flow when specifying a diagonal range by two-point instruction in a move/delete operation, and 4 is a process flow when searching a set ruled line table and selecting a corresponding ruled line. ~ in the drawings indicate connection points to corresponding numbers.

Next, while referring to Fig. 3 and Fig. 4, 1 to 4,
The operation of the method for searching for a corresponding ruled line in a word processor or the like according to the present invention will be explained.

First, when the ruled line key is selected on the operation unit 3, the flow shown in FIG. 41 starts.

In the case of the ruled line function, the ruled line control key input processing section 5 receives the current cursor position from the cursor control section 2. Let the coordinates of this cursor position be (x1, y1).

When setting a ruled line, the operator further specifies another point to be the end point, so the screen waits for key input again.

When the execution key is pressed after the cursor has been moved, the ruled line control key input processing section 5 retrieves the current cursor position from the cursor control section 2.
Let the coordinates retrieved at this point be (x2, y2).

The ruled line control key input processing unit 5 sends the coordinate information of these two points to the set ruled line table 9 along with an instruction signal indicating setting, and adds the table.

Following this operation, this ruled line information is sent from the set ruled line table 9 to the ruled line display control section 4 for display, and is displayed on the display device 1.

When the ruled line setting operation is completed, the flow returns to the start again.

Next, in the case of movement or deletion, the flow moves from FIG. 4 1 to FIG. 4 2 , and the cursor position (x1, y1) is sent to the corresponding ruled line search unit 6.

The applicable ruled line search unit 6 searches the set ruled line table 9 for the applicable ruled line. A detailed processing flow of the corresponding ruled line searching section in the corresponding ruled line searching section 6 is shown in FIG. 4, but this point will be explained later.

Here, we will explain the process of deleting and moving ruled lines in the fourth section.
The flows in FIGS. 2 and 3 will be explained first.

In Fig. 4 2, if the corresponding ruled line is placed above the specified cursor position (x1, y1),
The corresponding ruled line information is stored in the corresponding ruled line table, and is displayed as the corresponding ruled line, for example, as a broken line, on the display device 1 through the ruled line display control unit 4.

In the case of the ruled line deletion process, the ruled line data of the corresponding ruled line table 10 is deleted from the set ruled line table 9 and also from the screen of the display device 1.

In addition, in the case of movement, the ruled line calculation section 7 calculates the position after the movement in accordance with the instruction of the movement direction, and the ruled line data on the corresponding ruled line table 10 is updated. At the same time, dashed ruled lines are displayed on the display device 1 at the positions after the movement based on the updated data.

The operator moves the ruled line to the desired position while viewing such a display, and when the ruled line is moved to the desired position, inputs the execution key. By inputting this execution key, the data in the set ruled line table 9 is updated with the ruled line data in the corresponding ruled line table 10, and the normally displayed ruled line is displayed on the display device 1 at that position. When these deletion and movement processes are completed, the process returns from the bottom to the one shown in FIG. 4, respectively.

By the way, the cursor position (x1,
If the corresponding ruled line does not exist in y1), the flow moves from FIG. 4 2 to FIG. 4 3, and the ruled line control key input processing section 5 waits for input again.

When the operator performs a cursor movement operation and then presses the execution key, the cursor position (x2, y2) at that time is input from the cursor control section 2 to the ruled line control key input processing section 5.

The ruled line control key input processing unit 5 provides the inputted two-point cursor position (x1, y1) and (x1, y2) information to the corresponding ruled line search unit 6.

The corresponding ruled line search unit 6 searches the set ruled line table 9 for a ruled line that falls within the diagonally indicated range at the two cursor positions (x1, y1) and (x2, y2).

If the corresponding ruled line is not found, the process is immediately terminated and the flow returns from the flow shown in FIG. 4 3 to the flow shown in FIG. 4 1 again.

On the other hand, when the corresponding ruled line is found, the fourth
From FIG. 3 to FIG. 4, the flow moves to FIG. Start any necessary moves or deletions.

By the way, in the corresponding ruled line search method of this invention,
As shown in the flow in Figure 4, one point (x1, y1)
is specified, the information for each ruled line sequentially extracted from the set ruled line table 9 is compared with this cursor position information (x1, y1) to determine whether this point exists on the ruled line. Determine whether or not.

One ruled line can be either a vertical ruled line or a horizontal ruled line, so 1
Set the start and end points of the book's borders (xS, yS),
If (xE, yE), then the ruled line to be searched is either xS≠xE yS=yE or xS=xE yS≠yE.

In the case of horizontal ruled lines, since yS=yE, the determination of whether one point (x1, y1) is on a ruled line is as follows: xS≦x1≦xE y1=yS (=yE).

However, the coordinates of the starting point of the ruled line are smaller than the coordinates of the ending point. It goes without saying that a similar determination can be made in the opposite case as well.

In addition, in the case of vertical ruled lines, change the x of the upper horizontal ruled line to y
, just read y as x.

Next, in the case of two-point designation, the ruled line included in the diagonal range indicated by the cursor positions (x1, y1) and (x2, y2), that is, within the rectangular range, becomes the corresponding ruled line.

First, between x1 and x2, the smaller one is x1 and the larger one is x2.Similarly, regarding y1 and y2, the smaller one is y1 and the larger one is y2.

In this case, the ruled line to be searched and compared is determined to be the corresponding ruled line when x1≦xS≦x2 and y1≦yS≦y2, or when x1≦xE≦x2 and y1≦yE When ≦Y2.

Through such operations, information on the searched corresponding ruled line is added to the corresponding ruled line table 10.

The subsequent processing is similar to that described with respect to FIGS. 1 to 3.

Effects of the Invention According to the applicable ruled line search method of the present invention, when an operator specifies one point in the process of moving or deleting a ruled line in a word processor or the like,
If that one point is on a ruled line that has already been set, that ruled line will be set as the corresponding ruled line, and if the specified point is not on the ruled line, the next point will be specified. Therefore, two points are automatically specified, and a ruled line in which one or both of the start point and end point exists within the diagonal range specified by the two points is determined to be the corresponding ruled line.

Therefore, by adopting the applicable ruled line search method of the present invention, the operation when moving/deleting one, two, or more ruled lines as a target ruled line can be performed by specifying one or two points. It will be possible to do this in a unified manner.

Furthermore, since the number of operations required to select a corresponding ruled line in ruled line operations is significantly reduced, the burden on the operator is greatly reduced, operational errors are prevented, and the operational efficiency of word processors, etc. is improved. Many excellent effects can be obtained, such as:
