Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a ruled line input method in an interactive electronic device having an input device, a display device, a processor, and the like.

Conventionally, in interactive electronic devices such as word processors, there are the following two methods for inputting ruled lines.

(1) A method in which the operator determines the starting point of the ruled line using the starting point key on the input device and instructs the direction in which the line will be drawn.

(2) A method in which the operator determines the start and end points of ruled lines using the start and end point keys on the input device, and then connects them.

In the method (1) above, since the operator does not provide information on how far to draw the line, the device makes its own judgment and draws the line to an appropriate point. In this case, if the line drawn by the device differs from the operator's intention, there is a drawback that addition or deletion operations are required.

In addition, method (2) is used, for example, when trying to draw ruled line 1 as shown in FIG. 1 on the screen of a display device.
As shown in Figure 2, stop the cursor at position A, specify the start point of ruled line 1 using the start point key on the input device, then move cursor 2 to the right, and stop cursor 2 at position D. When you specify the end point of ruled line 1 using the end point key on the input device, a horizontal ruled line 1A is drawn above the character string ABCD, and then a new ruled line is drawn at the right position of D as shown in Figure 3. Indicate the starting point of , move cursor 2 one line down to the right of D,
When you specify the end point of the ruled line, a right vertical ruled line 1B is placed to the right of D.
is drawn. Similarly, the lower horizontal ruled line 1C and left vertical ruled line 1D of the character string ABCD are drawn, and the first
A framed ruled line 1 as shown in the figure is obtained. In this way, in method (2), information on the start point, end point, and length of the ruled line is provided, so the line is drawn as desired by the operator, but the start point and end point must be specified for each line. Therefore, in the case of a shape that requires a large number of ruled lines, the operation becomes complicated.

The present invention has been made in order to eliminate the drawback of the method (2) above, and its features include at least an input device, a display device, and a processor, means for permitting the input of ruled lines, and A ruled line input device comprising: means for sequentially inputting ruled lines along a locus of movement of a position indicated by a cursor while input of ruled lines is permitted by the input permission means;
The apparatus is provided with a means for erasing a ruled line when the ruled line has already been input on the locus of movement of the position indicated by the cursor while the input of the ruled line is permitted by the ruled line input permission means.

The present invention will be described in detail below along with examples.

4 to 6 are diagrams for explaining one embodiment of the present invention, and the same parts as in FIG. 2 are given the same symbols. When drawing a ruled line as shown in FIG. 1 on the screen of a display device according to this embodiment, as shown in FIG. After specifying the starting point, each time you move cursor 2 to the right,
Ruled line 1 is displayed at the position corresponding to the trajectory, and when cursor 2 moves to position D,
A horizontal ruled line 1A is drawn above the character string ABCD.
Next, as shown in Figure 5, move the cursor 2 down one line and draw the right vertical ruled line 1B, then move the cursor 2 to the left and move it to position A, ABCD.
Draw a horizontal ruled line 1C at the bottom of the character string, then move the cursor 2 up one line and draw a left vertical ruled line 1D. When the line drawing is completed, the end point is designated by the end point key of the input device.

In other words, without having to specify the start point and end point for each of the vertical, horizontal, horizontal, and vertical ruled lines 1A to 1D one by one, simply by specifying the starting point and end point once, each of the vertical, horizontal, left, and right vertical ruled lines 1A to 1D can be successively executed. You can subtract 1D.

Additionally, if you make a mistake in drawing too many ruled lines when moving the cursor, you can delete ruled line 1 by returning the cursor 2 to the specified position, as shown in Figure 6. .

Note that although this embodiment is a program executed by a processor such as a microcomputer, the present invention is not limited to this. For example, hardware may be configured by combining known circuits having the above functions. Of course, this is a good thing.

It goes without saying that the present invention can also be applied to ruled lines other than the framed ruled lines shown in FIG. 1, such as table layout ruled lines.

As explained above, according to the present invention, even if the shape is made up of a plurality of ruled lines, it is necessary to specify the starting point and ending point once for each ruled line, without specifying the starting point and ending point for each ruled line. Each ruled line can be drawn using the cursor, and if the ruled line is drawn too much due to an operational error when moving the cursor, the overdrawn portion of the ruled line can be deleted, making the operation extremely simple.
