Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for creating ruled lines used when creating a table using a document creation device, etc., and particularly relates to a method for creating a diagram using this tabulation function. This invention relates to a method for realizing arrows attached to frequently used leader lines etc. with simple operations.

Recently, with the progress of office automation, many document creation devices and the like have come into use. Normally, document creation devices create sentences by displaying characters entered from a keyboard on a display unit using a cathode ray tube or liquid crystal display, and then store the created sentences on a floppy disk or the like and print them out using a printer. .

This writing device usually has a tabulation function and can draw ruled lines continuously by pressing keys on the keyboard. Therefore, it is also possible to create diagrams using this tabulation function, and when diagrams are created, arrows are often added to leader lines and the like to indicate specific parts.

Therefore, it is necessary that the operation for expressing the line to which the arrow is attached is simple.

[Conventional technology]

FIG. 3 is a block diagram of a circuit showing an example of a document creation device.

The processor 1 reads the program stored in the ROM 2 and starts operating, controls the disk control circuit 11 to read the program from the floppy disk 12, and stores the program in the RAM.
Store in 3.

Information on the press of a character key is input from the keyboard 6 via the keyboard control circuit 5, and the processor 1 converts this information into a character code and stores it in the RAM 3 in accordance with instructions from a program read from the RAM 3.

The processor 1 also reads out a character pattern corresponding to this character code from the character generation circuit 4, sends it to the display control circuit 9, and displays it on the display section 10. Further, in response to instructions from the keyboard 6, sentences composed of character codes stored in the RAM 3 are stored on the floppy disk 12.

In response to instructions from the keyboard 6, the processor 1 reads the text stored on the floppy disk 12, sends it to the printer 8 via the printer control circuit 7, and prints it.

FIG. 4 is a diagram illustrating a conventional drawing method.

For example, !Vjl1 with an arrow as shown in Figure 4 (al)
5 and 16, the operator uses the tabulation function to move the cursor continuously by, for example, pressing the cursor movement key and the expansion function key on the keyboard 6. ) Create a diagram without arrows as shown.

When drawing a ruled line, an example of the state of the cursor and ruled line displayed on the display unit 10 is as shown in FIG. is displayed in the cursor 16.

When adding an arrow to the diagram in FIG. 4(b), the operator stops the cursor 17 at the tip of the line 16 in FIG. 4(a), for example, as shown in FIG. 4(d), and ” from the keyboard 6 and press the conversion key, the fourth
As shown in Figure (e), an arrow is displayed at the end of the ruled line.

[Problem that the invention seeks to solve]

As mentioned above, conventionally, to draw a leader line with an arrow in a diagram, the method is to draw the diagram using ruled lines, input the characters, and then convert, which makes the operation complicated. The problem is that it's annoying.

[Means for solving problems]

The above problem is solved by providing a means for displaying a ruled line or an arrow at the cursor position and a means for giving an instruction as to whether the line is a ruled line or a ruled line with an arrow. Forms a ruled line, expresses the ruled line at the cursor position that stops when forming the ruled line, and in the case of a ruled line with arrow instruction, expresses an arrow at the cursor position, forms a ruled line according to the cursor movement instruction, and stops when forming the ruled line ends. This problem is solved by the ruled line creation method according to the present invention, which expresses an arrow at the cursor position.

[Effect]

In other words, when drawing a ruled line, an arrow is displayed at the cursor position to indicate that a ruled line with an arrow is being created.
By making it possible to leave this arrow at the end point of creating a ruled line, it is possible to easily form a ruled line with an arrow.

By doing this, in the same way as when drawing ruled lines,
Since it is possible to express an arrow at the end of a leader line, etc., it is possible to eliminate the need for complicated operations as in the past.

〔Example〕

FIG. 1 is a diagram illustrating an embodiment of the present invention, and FIG. 2 is a flowchart illustrating the operation of FIG. 1.

The operator presses, for example, a cursor movement key and a specific shift key on the keyboard 6 shown in FIG. When the processor 1 detects the key force, it checks whether it is a ruled line as shown in FIG. 2. If it is not a ruled line, it moves to other processing, and if it determines that it is a ruled line instruction, it checks whether there is an arrow.

Since the keys to be pressed on the keyboard 6 are different for normal ruled lines and those with arrows, the processor 1 displays normal ruled lines in the cursor 17 unless the keys are pressed with arrows. In the case of an arrow, the arrow is displayed in the cursor 17 as shown in FIG. 1(a).

If the cursor movement key is held down, the processor 1 moves the ruled line in the direction indicated by the cursor movement key (see FIG. 1).
Pull as shown in b). When the cursor movement gear is restored, the specific shift gear is also restored, and the end is instructed, the processor 1 leaves an arrow at the stop position of the cursor 17 and moves the cursor 17 to the next position, as shown in FIG. 1(C). move it to

〔Effect of the invention〕

As explained above, when creating a diagram using the tabulation function of a document creation device, when forming a line with an arrow in the diagram, the present invention draws ruled lines (as in the case of drawing ruled lines). This can be achieved by pressing a specific shift key instead of pressing .
