In the case of a document creation device that handles dotted lines, thick lines, etc., it is necessary to consider not only the intersection and branching of ruled lines, but also the connection of ruled lines of different line types.

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 device that can easily generate ruled line codes of multiple line types.

Means for Solving the Problems In order to solve the above problems, the present invention provides an input section for inputting characters and ruled lines and key operations, and a character code for storing characters and ruled lines input from the input section. A buffer, a display unit that displays the contents of the character code buffer, and a data structure in the character code buffer,
By providing a specific code in the first byte to indicate that the data at the position is a ruled line code, and a ruling line bit corresponding to the elements in the four directions of the top, bottom, left, and right that make up the ruled line in the second byte, Equipped with a ruled line code generation unit that generates an optimal ruled line code, it is easy to move the cursor in the up, down, left and right directions, as well as the content of data already stored in the character code buff 7a, as well as the connection mode of ruled lines of multiple line types. A ruled line code can be generated and displayed on a display screen.

Effect of the present invention With the above-described configuration, the present invention determines the ruled line codes in four directions adjacent to the position in question, and then determines the ruled line code in the position, as was done in conventional document creation devices. There is no need to perform such complicated processing, and a ruled line code can be easily generated by simply manipulating the ruled line bits in the ruled line data 5° structure at the position and the position adjacent to the cursor movement direction. In addition, there is no need to have a large number of ruled line pattern data consisting of combinations of ruled lines of various line types, as is the case with ordinary document creation devices, and instead a ruled line pattern at the relevant position can be generated by synthesizing the minimum necessary basic ruled line patterns. Therefore, memory-efficient processing can be performed.

Embodiment FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. A key code input from the input device 11 is determined by an input key determination circuit 12 as to whether it is a cursor key or an ANK (alpha numeric) key. If the key code input from the input device 11 is an ANK key, the character code generation unit 4 converts it into a character code, stores it in the corresponding position of the character code back arrow indicated by the character code buffer pointer 6, and then creates the character pattern. It is converted into a character pattern by the generator 8 and displayed on the display device 91 via the display control circuit 92.

When the key code input from the input device 11 is a cursor key, the cursor is normally moved in the direction of the cursor movement key input by the cursor control unit 2. When generating ruled lines, the cursor control unit 2 works in conjunction with the ruled line code generation unit 3,
A ruled line code is generated by manipulating the ruled line bit at the position indicated by the character code buffer pointer 5 and at a position adjacent in the moving direction of the input cursor key, and is stored in the character code buffer 6. Thereafter, the ruled line code is converted into a ruled line pattern by the ruled line pattern generation circuit 72 according to the information in the ruled line basic pattern section 71, and is displayed on the display section 91 via the display control circuit 92.

FIG. 2 (person) is a diagram showing an example of the data structure expressing the ruled line code in the character code buffer and the correspondence between the ruled line bits in the ruled line data and the constituent elements of the ruled line pattern in four directions, top, bottom, left, and right. In Figure 2 (person), ■ is to the right of the ruled line pattern component, ■ is to the top, ■ is to the left,
■ corresponds to the downward direction.

FIG. 2(B) is a diagram showing an example of the correspondence between ruled line types and ruled line bits in a ruled line code. In Fig. 2 (B), for example, when the ruled line is a solid line (01), when it is a dotted line (1o), when it is a thick line (11), and when the ruled line is deleted (0
0) to a predetermined position within the ruled line code.

FIG. 2(C) is a diagram showing how ruled lines are generated as the cursor moves. As the cursor moves in the up, down, left, and right directions, bit operations are performed at the relevant position and at positions adjacent to the cursor movement direction.

FIG. 2(D) is a diagram showing the correspondence between the 12 basic ruled line patterns and the ruled line bits in the case of three line types, and the numbers in parentheses ( ) represent the ruled line bits.

FIG. 2(E) is a diagram showing how a ruled line pattern is generated. In FIG. 2(E), among the ruled line pattern components, ruled lines are generated that have dotted line elements in the right direction, solid lines in the upper and lower directions, and thick line elements in the left direction.

FIG. 3 is a flowchart showing an overview of ruled line generation processing. In FIG. 3, the input key accepted from the input unit in step 101 is determined in step 102 as to whether it is a λNK key or a cursor key, and if it is an ANK key, the process branches to the character code generation process; For example, in step 103, the current ruled line type is determined, and in step 104, the direction of movement of the cursor is determined. Steps 105 and 10
6, a ruled line code at the current position is generated, and a ruled line pattern is generated and displayed from the ruled line bit configuration at the current position. The cursor is moved in the direction of the input cursor key in step 107, and in steps 108 and 109, a ruled line code at a position adjacent to the current position is generated, and a ruled line pattern is generated from the ruled line bit configuration at the position adjacent to the current position. indicate.

Effects of the Invention As explained above, according to the present invention, an optimal ruled line code can be easily generated at the intersection or branching point of ruled lines according to the manner of connection between ruled lines of different line types, and the necessary minimum code can be easily generated. A ruled line pattern can be efficiently generated from a basic ruled line pattern, and is extremely useful when performing ruled line processing in a document creation device.
