BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation device having a ruled line editing function capable of creating, deleting, moving, copying, etc. ruled lines.

0002

2. Description of the Related Art Generally, a document creation device is provided with a ruled line editing function for editing ruled lines, such as creating, deleting, moving, copying, etc., in order to create a table or the like in a document. In this type of document creation device, when editing created ruled lines, the ruled lines to be edited (excluding creation) are specified either in a rectangular range or individually. For example, if two diagonal points indicating a rectangular range are specified for a ruled line that has already been created, the system ruled line ( (for example, a dashed line). In this way, when specifying ruled lines to be edited,
The start and end points of the ruled line need to be specified (included within the rectangular range).

[0003] When a table or the like is created using a combination of ruled lines, the starting and ending points of each ruled line are set on the ruled lines that make up the outer frame of the table or on the already created ruled lines. be done.

As described above, in the ruled line editing function of conventional document creation devices, when specifying a ruled line to be edited, it is necessary to specify the starting point and ending point of the ruled line. That is, it is not possible to partially edit the ruled lines, which limits the operation of the ruled line editing function.

[0005] Furthermore, when creating a table, the start and end points must be specified for each ruled line constituting the table, making the operation complicated.

The present invention has been made in view of the above-mentioned points, and includes a ruled line editing function (designation of ruled lines to be edited,
The purpose of the present invention is to provide a document creation device with improved operability in (table creation).

Next, the procedure for specifying a ruled line to be edited in this embodiment will be explained with reference to the flowcharts shown in FIGS. 2 and 3. As an example, assume that a table as shown in FIG. 4 is created by a combination of ruled lines. It is assumed that the ruled lines shown in the figure are created by specifying a starting point and an ending point. Ruled line data buffer 8
Ruled line data (starting point/end point position, ruled line type, etc.) regarding each ruled line is stored in , and can be processed for each vertical ruled line or horizontal ruled line. Note that a description of the case where the starting point and ending point are included within a rectangular range as in the conventional case will be omitted.

[0021]Here, the case of deleting ruled lines will be explained as an example. First, when an instruction is given to delete a ruled line, a process for specifying the target ruled line is started, and a screen as shown in FIG. 4 is displayed. Note that the arrow in the figure is a cursor for specifying coordinates.

Here, a starting point and an ending point indicating a rectangular range for specifying the target ruled line are input (step A1). When the cursor is moved to a desired position on the screen shown in FIG. 4 and the "Select/Execute" key is pressed, the starting point position is determined and a screen for requesting end point designation as shown in FIG. 5 is displayed. Similarly, the end point position is determined when the cursor is moved to the desired position and the "Select/Execute" key is pressed. This rectangular range can be specified regardless of the starting and ending positions of ruled lines that have already been created.

When the starting point and end point indicating the rectangular range are specified, horizontal ruled lines included in the vertical width of the rectangular range are searched from the ruled line data stored in the ruled line data buffer 7 (step A1). For example, as shown in Figure 6, if we consider the upper left as the origin, the horizontal direction as the X coordinate, and the vertical direction as the Y coordinate, the Y coordinate of the starting point (Y1) and the Y coordinate of the ending point (Y2) of the rectangular range.
Find the ruled line data of the horizontal ruled line that has the Y coordinate of the starting point or ending point between the . In the following description, the position of the point that defines the position of the ruled line is such that the point with the smaller coordinate value is the starting point, and the point with the larger coordinate value is the ending point.

If the corresponding ruled line data is found through this search, the intersection point between the horizontal ruled line and the vertical frame of the rectangular range is found based on the X coordinate of the starting point and the X coordinate of the ending point (Step A
3, A4).

If an intersection exists, the ruled line data is changed based on the coordinate position of the intersection (step A6). The details of this process are shown in the flowchart of FIG. 2
If two intersection points are obtained, that is, when the ruled line passes through the rectangular range, the unspecified ruled line is the ruled line defined by the starting point of the original ruled line and the first intersection, and the ruled line defined by the starting point of the original ruled line and the first intersection point. A ruled line defined by the end point of the ruled line is determined, and a ruled line defined by the first intersection point and the second intersection point is determined as the specified ruled line within the rectangular range (steps B1 and B2).

[0026] Furthermore, when one intersection point is obtained, if the starting point of the ruled line is included within the rectangular range, a ruled line between the intersection point and the end point of the original ruled line is determined as an unspecified ruled line, and the specified point within the rectangular range is A ruled line based on the starting point and intersection of the original ruled line is determined as the ruled line (steps B3 and B4). If the end point of the ruled line is included in the rectangular range, a ruled line formed by the intersection with the starting point of the original ruled line is calculated as an unspecified ruled line, and a ruled line formed by the intersection point and the end point of the original ruled line is calculated as the specified ruled line within the rectangular range. (steps B3, B5).

Next, the data of the specified ruled line within the rectangular range obtained in step A6 is stored in the ruled line data work buffer 8 as an editing target (step A7).
. Also, the original ruled line data in the ruled line data buffer 7 is
The data is changed to the unspecified ruled line data obtained in step A6. Thereafter, the process is repeated for each horizontal ruled line in the same manner (steps A2 to A7). When the processing for all horizontal ruled lines is completed, the process moves to vertical ruled line processing (step A8).

Vertical ruled lines are also processed in the same way as horizontal ruled lines to obtain ruled line data within a rectangular range (
Steps A8 to A13).

[0029] Based on the obtained ruled line data, a dashed line indicating the rectangular range is displayed as shown in FIG. 7, and the specified ruled line is changed to a system ruled line indicating that. . In this state, "Select/Execute"
When the key is pressed, as shown in FIG. 8, the ruled lines displayed as system ruled lines are erased, and the original ruled line data in the ruled line data buffer 7 is changed to the unspecified ruled line data obtained in step A6. do. Please note that the content of border editing is
If there is no change in the original ruled line display such as copying, there is no need to change the original ruled line data.

When the ruled line data stored in the ruled line data work buffer 8 is copied or moved, the coordinate position is updated according to an instruction using a cursor key, for example.

In this way, it is possible to specify a ruled line to be edited even if the starting point and end point are not included in the rectangular frame, thereby eliminating operational restrictions and improving the operability of ruled line editing.

Next, the procedure for creating a table using the ruled line editing function (automatic ruled line creation) will be explained with reference to the flowchart shown in FIG. Usually, when creating a ruled line, it is done by indicating the positions of the starting and ending points of the ruled line. When creating a rectangular frame such as the outer frame of a table, 2
This is done by pointing to a point.

First, as shown in FIG. 10, when the outer frame and vertical ruled lines of the table have been created in advance, for example, when "Function 1" + cursor key (or "ruled line" key may be pressed) is pressed, Automatic ruled line creation is performed from the cursor position in a predetermined direction to the already created ruled lines.

First, when an instruction to automatically create a ruled line is input, if the cursor position is on a ruled line and that ruled line is a vertical ruled line, the vertical ruled line stored in the ruled line data buffer 7 is searched and the cursor is The coordinate position of the intersection of the position and each vertical ruled line is determined (steps C1 to C3).

Then, a horizontal ruled line is generated between the initial position indicated by the cursor and the vertical ruled line with the largest coordinate value, as shown in FIG. (steps C4, C5
). Hereinafter, this display state will be referred to as rubber band display.

When the "Next Candidate" key is pressed in the state of the rubber band display as shown in FIG. 11, the initial position indicated by the cursor and the vertical position with the next largest coordinate value are A horizontal ruled line is generated between the ruled lines and a rubber band is displayed. That is, each time the "Next Candidate" key is pressed, horizontal ruled lines are sequentially generated between another vertical ruled line and a rubber band is displayed, as shown in FIGS. 11, 12, 13, and 14. Let's do it.

When the "select/execute" key is pressed while any horizontal ruled line is displayed, the starting and ending positions of the horizontal ruled line at that time are stored in the ruled line data buffer 7, and the data shown in FIG. 15 is stored. (In the figure, the ruled lines are created up to the outer frame.) Display the confirmed ruled lines (step C8).
, C9).

On the other hand, if the initial position of the cursor is on a horizontal ruled line, the horizontal ruled line is retrieved from the ruled line data buffer 7 (step C10), and then vertical ruled lines are generated by the same procedure as steps C4 to C9. (Step C1
1 to C16).

In FIG. 10, the initial state is a case where the cursor is located on the outer frame, but the cursor may be located on any ruled line. In addition, ruled lines are generated sequentially between ruled lines with large coordinate values and displayed as a rubber band, but the order in which they are generated is particularly limited, for example, ruled lines are generated sequentially between ruled lines with small coordinate values. Not done.

[0040] In this way, when creating ruled lines, it is not necessary to specify the start point and end point for each ruled line, so operations for creating tables, etc. can be simplified.

[0041]

As described above, according to the present invention, restrictions on specifying ruled lines to be edited are alleviated, and the creation of ruled lines when creating tables, etc. is simplified, so that the ruled line editing function is improved. This makes it possible to improve the operability of the machine.
