Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus, and more particularly, to creating an optimum ruled line code according to an intersection or a branch point of a ruled line in a process of creating a ruled line code. It relates to the device.

Conventional technology When generating a ruled line code and displaying it on the display screen, specify the start and end points of the ruled line with the cursor position, or enter the coordinate values with numbers, or move the cursor. There is a method of generating ruled lines. However, in either method, after determining whether the character code is a ruled line by referring to the character code at the upper position of the position, the character code at the lower position, the character code at the left position, and the character code at the right position. It is necessary to generate a ruled line code at the position according to the mode of ruled line connection (for example, Japanese Patent Laid-Open No. 58-14239).

Problems to be Solved by the Invention In such a conventional technique, the ruled line code of the position must be determined after determining the ruled line codes in the four directions of up, down, left, and right that are adjacent to the position. It's complicated. The present invention has been made in view of the above problems, and an object of the present invention is to provide a document creation apparatus that can easily generate ruled lines.

Means for Solving the Problems In order to solve the above problems, the present invention provides an input unit including a character key and a cursor moving key, and a cursor for moving and controlling an input coordinate position of the cursor according to an operation of the input unit. Adjacent two before and after the cursor movement according to the direction of the cursor movement key input from the control unit and the input unit.
It is composed of a ruled line code generation unit that generates a ruled line code at one input coordinate position, a character code buffer that stores the characters input from the input unit and the ruled line code, and a display unit that displays the contents of the character code buffer. In addition, when the ruled line is generated, the data structure of the ruled line code is composed of a code for specifying that it is a ruled line and a ruled line configuration bit corresponding to the presence / absence of each of the constituent elements of the ruled line in the four directions of up, down, left and right. , The ruled line configuration bit or ruled line pattern other than the input coordinate position is identified by turning on or off the ruled line configuration bit corresponding to the direction of cursor movement at two adjacent input coordinate positions before and after the cursor movement. Without doing so, the ruled line code is generated in the character code buffer.

According to the present invention, with the above configuration, the ruled line code generation unit calculates the real address in the character code buffer corresponding to the cursor position and the position adjacent to the direction designated by the cursor movement key of the input unit, and the ruled line configuration of the cursor position is calculated. By setting the bit corresponding to the moving direction among the bits corresponding to the moving direction and the ruled line composing bit at the position adjacent to the moving direction, it is not necessary to judge the ruled line code in the up, down, left, and right directions. An optimum ruled line code can be generated at a position adjacent to the position and the cursor movement direction, and a ruled line pattern corresponding to this ruled line code can be displayed on the display unit.

Practical Example FIG. 1A is a diagram showing the correspondence between the data structure expressing the ruled line code in the character code buffer, the ruled line configuration bits in the ruled line data structure, and the components of the ruled line pattern in the four directions of up, down, left and right. In FIG. 1A, 1 is to the right of the ruled line pattern component, 2 is upward, 3 is left, and 4
Corresponds to the downward direction.

FIG. 1B is a diagram showing how ruled lines are generated when the cursor movement key of the input unit is pressed. In FIG. 1B, a is a cursor movement key to the right, b is a cursor movement key to the left, c is an upward cursor movement key, and d is a downward cursor movement key. It shows how ruled lines are generated at a position adjacent to the cursor position and the cursor movement direction when pressed.

FIG. 1C is a diagram showing correspondence between 15 types of ruled line patterns and ruled line configuration bits.

FIG. 2 is a diagram showing an example of an embodiment configuration of the present invention. The character key input from the input section keyboard 1 is stored in the character code buffer 6 which is converted into a character code by the character code generation section 4 according to a predetermined procedure. Normally, the cursor on the display screen is used to indicate the currently inputable position on the display unit, and the cursor control unit 3 moves the cursor position in the direction of the input cursor movement key. After the ruled line creation is instructed from the input unit 1, the cursor movement key is used to create the ruled line code. The ruled line code generation unit 5 generates a ruled line code optimum 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 6 into a character pattern and displays the character pattern, and displays the ruled line pattern created by the ruled line pattern creating unit 7 on the display unit 9.

The procedure for creating a ruled line will be described by taking the case of creating a ruled line as shown in FIG. 3 as an example. It is assumed that the cursor is located at the coordinate position of X = 2 and Y = 2 when the ruled line generation is instructed in FIG. When the right move key is entered, the right bit at the coordinate position of X = 2, Y = 2 and the left bit at the coordinate position of X = 3, Y = 2 are set, and the "-" and "-" ruled line codes are respectively set. Is generated. When the rightward movement key is subsequently input, the rightward bit at the coordinate position of X = 3, Y = 2 is set, and the ruled line configuration bit at this position is set to the leftward and rightward bits. It changes to "-". Similarly, while generating ruled line code, X = 8, Y
After moving the cursor to the coordinate position of = 2, if you press the downward movement key, the downward bit of the coordinate position of X = 8, Y = 2 is set, and the ruled line configuration bit at this position is the leftward and downward bits. It has been set, The ruled line code is generated and the upper bit of the coordinate position of X = 8, Y = 3 is set. When the downward movement key is continuously input, a ruled line code "|" is generated at the coordinate position of X = 8, Y = 4. Focusing on the coordinate position of X = 8, Y = 4, when the ruled line code of "|" is generated, the coordinates of X = 8, Y = 4 are changed from X = 7, Y = 4. When the cursor moves to a position, the bit to the left of that position is set. The ruled line code of is generated, and when the rightward movement key is input, the rightward bit is set. The ruled line code of is generated.

The same applies to the coordinate positions of X = 3 and Y = 2. A ruled line code of "-" is already generated at this position, but when the cursor is moved from the coordinate position of X = 3, Y = 3 to the coordinate position of X = 3, Y = 2 by the upward movement key,
The down bit for that position is set, The ruled line code of is generated.

EFFECTS OF THE INVENTION As described above, according to the present invention, it is possible to extremely easily generate an optimum ruled line code according to an intersection or a branch point of a ruled line. Further, even when the ruled line is erased, by resetting the ruled line configuration bits at the position adjacent to the cursor position and the cursor moving direction, exactly the same as the ruled line generation,
The ruled lines can be erased very easily, which is extremely useful for generating and deleting the ruled lines in the document creating apparatus.
