Abstract

PURPOSE:To easily draw a delimiter line in the middle between stages by designating two points out of four corners between stages. CONSTITUTION:When an icon on a display device 2a is used to designate a longitudinal direction or a transverse direction in which a ruled line is drawn and the coordinates of two points are designated by a mouse 2d, the length of the major side and that of the minor side of a rectangle having these points as two points on a diagonal line are calculated, and the coordinates of middle points of major and minor sides are calculated, and the rules line is so drawn that it passes through middle points of the major sides or minor sides in accordance with the designated direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruled line drawing mechanism, and more particularly to a ruled line drawing mechanism for a dividing line drawn in the center between paragraphs (hereinafter referred to as a space) of sentences of a Japanese word processor.

[0002]

2. Description of the Related Art Conventionally, in the ruled line drawing mechanism of this type of Japanese word processor, an operator designates the center of a column by calculation and draws a ruled line for dividing between columns according to the designation.

[0003]

In the above-described conventional ruled line drawing mechanism, since the operator specifies the center of the step by calculation, there is a problem that it takes time to draw the ruled line.
Furthermore, there is a drawback that the ruled line may be drawn off the center due to the calculation.

[0004]

The ruled line drawing mechanism of the present invention includes a first means for specifying whether to draw a ruled line in a vertical direction or a horizontal direction, and a second means for specifying two points among four corners between steps. 2 means, means for calculating the lengths of the horizontal side and the vertical side of the rectangle by regarding the coordinates of the two points designated by the second means as two points on the diagonal of the rectangle, and the rectangle Means for calculating the coordinates of the midpoint of the side length of the rectangle, and when the designation by the first means is the vertical direction, the midpoint of the sides of the rectangle in the horizontal direction is specified. And a means for drawing a ruled line so as to pass through the midpoints of the sides.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings.

Referring to FIG. 1, the embodiment of the present invention includes a display device 2a, a Japanese word processor body 2b, a keyboard 2c, and a pointing device (hereinafter referred to as a mouse) 2d.

FIG. 4A shows an example of a column set having columns. In the case of the example, the space between steps is the line between point 3a and point 3b and point 3c.
-Means between the line between the points 3d. The dividing line between the steps, that is, the ruled line, starts from the midpoint between 3a and 3b, and 3c
The midpoint of d is set as the end point. If the operator uses a calculation to specify the intermediate point, it may take time and a deviation may occur.

FIG. 2 is a view of a display screen including icons displayed on the display device 2a in the ruled line drawing mechanism of this embodiment. The icon 4a indicates that the ruled line is drawn in the vertical direction, and the icon 4b indicates that the ruled line is drawn in the horizontal direction.

Next, the operation of the embodiment shown in FIG. 1 will be described with reference to FIG. 3 as an example in which a ruled line is drawn on a column as shown in FIG. 4B.

First, since the ruled line between columns in FIG. 4B is in the vertical direction, the icon 4a in FIG. 2 is designated by the mouse 2d in FIG. Then, as shown in FIGS. 2 and 4B, the upper left 5a between the steps is designated as the starting point, and the lower right 5b between the steps is designated as the end point, and the mouse 2d is designated. Accordingly, in the main body 2b, step s
It is determined whether or not the icon of 4a or 4b is designated in 1. When the icon is designated, the coordinates of the two points designated by the mouse 2d are received in step s2, and the calculation means obtains the coordinates of the four points of the rectangle which are regarded as two diagonal points by calculation in step s3. Step s4
It is determined whether to draw the ruled line in the vertical direction or in the horizontal direction in step S2.
The coordinates of the middle point of the two points and the lower two points are calculated. That is, the lateral intermediate coordinates are calculated. In the case of the horizontal direction, in step s6, the coordinates of the middle points of the two points on the left and the two points on the right of the four points of the rectangle are calculated. That is, the vertical intermediate coordinates are calculated. Then, in step s7, the intermediate points are connected by ruled lines by the ruled line drawing means. As a result, as shown in FIG. 4C, the ruled line 6a is drawn in the vertical direction connecting the centers of the steps.

It is also possible to calculate only one of the long side and the short side of the corresponding rectangle based on the icon designation and calculate the midpoint thereof, or both the long side and the short side. Alternatively, all intermediate points between the two may be calculated and selected from the calculation results based on the icon designation.

[0012]

As described above, according to the present invention, it is possible to easily draw a dividing line in the middle of the steps by only designating two points among the four corners of the steps to draw the dividing lines between the steps. There is an effect that can be done.
