Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document creation device, and more particularly to a document creation device that generates an optimal ruled line code according to intersections and branching points of ruled lines in the process of generating ruled line codes. It is related to the device.

Conventional technology When generating a ruled line code and displaying it on the display screen, the starting and ending points of the ruled line must be specified by the cursor position, or
Alternatively, there is a method of inputting coordinate values as numbers, or a method of generating ruled lines as the cursor moves. However, in either method, the character code at the upper position, the character code at the lower position, the character code at the left position,
After determining whether the character code is a ruled line by referring to the character code at the right position, it was necessary to generate a ruled line code at that position depending on the manner of connecting the ruled lines (for example, 14239).

Problems to be Solved by the Invention In such conventional techniques, the ruled line code of the relevant position must be determined after determining the ruled line codes of the four directions adjacent to the relevant position, and the ruled line generation becomes very slow. It has become complicated. In view of the above-mentioned problems, the present invention provides a text that can easily generate ruled lines.In order to solve the above-mentioned problems, the present invention provides an input section for inputting characters and ruled lines, a character code buffer for storing character codes of characters and ruled lines, It has a display section that displays the contents of this character code buffer, and a function that generates ruled lines using the cursor movement keys of the input section, and positions above and below the cursor position that indicates the current input position in the document. 1. A ruled line code generation unit that operates the ruled line configuration bits of the position and the moving direction position as the cursor moves to the left and right positions, and the code 1 specifies that the ruled line is a ruled line in the data structure of the ruled line code.
An optimal ruled line code can be easily generated by providing the bytes and ruled line configuration bits corresponding to the constituent elements in the four directions (up, down, left, and right) that constitute the ruled line.

According to the above configuration, the ruled line code generation section calculates the real address in the character code buffer corresponding to the cursor position and the position adjacent to the direction specified by the cursor movement key of the input section, and generates the ruled line at the cursor position. By setting the bit corresponding to the moving direction among the constituent bits and the bit corresponding to the moving direction among the ruled line constituent bits at positions adjacent to the moving direction, there is no need to judge the ruled line code in the vertical and horizontal directions. The optimal ruled line code can be generated for the relevant position and the adjacent position in the cursor movement direction.
In addition, a ruled line pattern corresponding to this ruled line code can be displayed on the display section. Embodiment 1 FIG. In Figure 1A, which is a diagram showing the correspondence with constituent elements in four left and right directions, 1 indicates the right direction of the ruled line pattern constituent elements, 2 indicates the upward direction, 3 indicates the left direction, and 4 indicates the downward direction. Compatible.

FIG. 1B is a diagram showing how ruled lines are generated when the cursor movement key of the input section is pressed. Figure 1 BIICb, a is pressed by the right cursor movement key, b is pressed by the left cursor movement key, c113 is the upward cursor movement key, and d is pressed by the downward cursor movement key. This shows how ruled lines are generated at the cursor position and at positions adjacent to the cursor movement direction when the cursor is moved.

FIG. 1C is a diagram showing the correspondence between 15 types of ruled line turns and ruled line configuration bits. FIG. 2 is a diagram showing an example of the implementation configuration of the present invention.

Character keys input manually from the input section keyboard 1 are converted into character codes by a character code generating section 4 according to a predetermined procedure and stored in a character code buffer 16. Normally, the cursor on the display screen is used to indicate the currently available input position on the display, and the Kahnl control unit 3 is a human-powered unit that moves the cursor position in the direction of the input cursor movement key. After the creation of a ruled line is instructed from step 1, the cursor movement keys are used to create a ruled line code. The ruled line code generation unit 6 generates an optimal ruled line code for the position and a position adjacent in the direction of the input cursor movement key, and stores it in the character code buffer 6. The screen control unit 8 converts the character code stored in the character code buffer θ into a character code turn and displays it.
The ruled line pattern created by the ruled line turn creation section 7 is displayed on the display section 9.

The procedure for generating a ruled line will be explained by taking as an example the case of creating a ruled line as shown in FIG. Assume that when the generation of ruled lines is instructed in FIG. 3, the cursor is at the coordinate position of X:2, Y==2. When you press the right movement key, X=2, Y=2
The right bit of the coordinate position and the left bit of the coordinate position of X:3, Y=2 are set, respectively
- A ruled line code for J is generated. 0 When the right direction movement key is input successively, the right direction bit at the coordinate position of X=a, Y=2 is set, and the ruled line configuration bits at this position are the left direction and right direction bits. is set, and the ruled line code changes to "-". While generating the ruled line code in the same way, X:8. After moving the cursor to the coordinate position of Y=2, input the downward movement key, and it will be set to X=8. The lower bit of the coordinate position of Y=2 is set, and the left and lower bits of the ruled line configuration bits at this position are set, and a ruled line code of "]" is generated.

The upper bit of the coordinate position of X=a, Y:3 is set. If you continue to input the downward movement key, X=s
, a ruled line code of "1" is generated at the coordinate position of Y=4. If we pay attention to the coordinate position of X=a, Y=4, we can see that a ruled line code of "1" is generated,
7. When the cursor moves from Y=4 to this X=s, Y=4 coordinate position, the left direction bit of that position is set, a ruled line code of "H" is generated, and then the right direction movement key is pressed. When input, the right direction bit is set and a "±" ruled line code is generated.

The same thing can be said about the coordinate position of X=3 and Y=2. A ruled line code of "-" has already been generated at this position, but by pressing the upward movement key from the coordinate position of X=3.7=3. When the cursor moves to the coordinate position of Y=2, the lower bit of the position is set, and a ruled line code of "Ding" is generated.

Effects of the Invention As described above, according to the present invention, it is possible to extremely easily generate an optimal ruled line code according to the intersections and branching points of ruled lines. In addition, when erasing ruled lines, by resetting the ruled line configuration bits at the cursor position and positions adjacent to the cursor movement direction, it is possible to erase ruled lines extremely easily, just like creating ruled lines, and create documents. This is extremely useful when creating and erasing ruled lines in the device.
