Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underline input device for drawing an underline in a sentence created by a document creation device such as a word processor.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram showing a sentence creating apparatus using a conventional underline input method.

In the figure, when a character or a designated position for drawing an underline is input through the keyboard 11,
The control unit (CPU) 12 stores the document data composed of these input characters in the document buffer 13 and displays it on the display unit 14, and the print command is issued via the keyboard 11. When input, print control for outputting the document in the document buffer 13 via the printer 15 is performed. In this case, one character code is usually composed of 2 bytes.

Here, for example, when a document whose title is "Business Trip Report" is created as shown in FIG. 4, an underline is drawn to the title "Business Trip Report" as shown in FIG. This underline display processing, printing processing, etc. are performed by setting the eighth underline bit of the 2-byte character code to "1" as shown in FIG.

[0005]

However, in the document shown in FIG. 4, for example, a line feed code is usually added after the title "business trip report", so that the title "business trip report" as shown in FIG. When the underline is drawn by extending one character to the left and right of the calligraphy, the underline cannot be drawn by extending one character on the right side by the line feed code.

Therefore, in the above-described conventional underline input method, when the underline is drawn by protruding by one character on the right side of the title "business trip report", the operator follows the title "business trip report". It is necessary to input a space and then add a line feed code, which is a troublesome operation and troublesome.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an underline input device which can easily draw an underline even in a region where there is no character.

[0008]

In order to achieve the above-mentioned object, an underline input device of the present invention comprises an input means for inputting a character and a pointing position at which an underline should be drawn.
Storage means for storing the character code and position of the character input through the input means; and when the underline indicated position is input through the input means, the underline indicated position is stored in the storage means. It is determined whether or not the character code is already stored. If the character code is stored, an underline bit is set in the character code,
If a character code is not stored, a space code is inserted in the position and an underline setting means for setting an underline bit in the space code is provided. To do.

[0009]

According to the underline input device of the present invention, when an instruction position for drawing an underline is input, the underline setting means determines whether a character exists at the indicated position of the underline in the storage means. Determine whether or not. Here, if a character is stored, the underline bit is set in the character code. On the other hand, when the character is not stored, the space code is inserted at that position and the underline bit is set in the space. Therefore, it is possible to easily draw an underline without needing to enter a space not only in a region having a character but also in a region having no character.

From the following examples of the present invention, such effects of the present invention will be further clarified, and other effects of the present invention will be clarified.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a document creating apparatus including an underline input device according to an embodiment of the present invention, and FIG. 2 is a flowchart for explaining the operation of the underline input device of FIG. It is

In FIG. 1, a keyboard 21 constituting an example of input means is a character input key for inputting various characters and various functions for inputting a designated position where an underline should be drawn. Keys, and these key operation processes are performed by the control unit (CPU) 22. The control unit 22 edits a document in the document buffer 23, which is an example of a storage unit, according to characters and various commands input via the keyboard 21, and the display unit 24 edits the document. Performs display control for displaying. Further, when a print command is input via the keyboard 21, the control unit 22 performs print control for outputting the document in the document buffer 23 via the printer 25. The character presence / absence checking unit 26, which constitutes an example of the underline setting means together with the control unit 22, receives the underline designated position via the keyboard 21 and determines whether or not a character exists at that position. To judge. Then, depending on the result of the judgment, an underline bit is set in the character code as will be described later, or a space code is inserted and the space code is inserted.
It is configured to set the underline bit in the command line.

In this case, one character code is usually composed of 2 bytes, and the underline display processing and printing processing are the same as those of the 8th character code of 2 bytes as shown in FIG. This is done by setting the underline bit to "1".

Next, the operation of the embodiment configured as described above will be described with reference to FIG.

In the figure, when the underline pointing position is input via the keyboard 21 (step S1), the control unit 22 checks the input position information on the document buffer 23 for the presence / absence confirmation unit.
The presence / absence confirming unit 26 discriminates whether or not a character already exists at this designated position, that is, whether or not a character code is already stored at the designated position in the document buffer 23 (step S2).

When there is no character at the underline designated position (NO), the presence / absence confirmation unit 26 inserts a space for one character at that position (step S3), and the control unit to that effect. Notify 22 and proceed to step S4. If a character exists at the underline designated position (YES), step S2
Directly to step S4. In step S4, the control unit 22 sets the 8th underline bit of the 2-byte code in the document buffer 23 to "1", and similarly, in step S5, the keyboard 21 is set. When the underline designated position is input via (YES), the process returns from step S5 to step S1, and the above process is repeated.

Therefore, when the title "business trip report" is extended by one character to the left and right and is underlined as shown in FIG. 5, when the character exists, as shown in FIG. 8th underline bit is set to "1". If no character is present, a space code is inserted at the underline indication position and the 8th underline bit is set to "1". Therefore, the underline can be automatically input even in the area where there is no character.

[0018]

As described in detail above, according to the present invention, when an instruction position for drawing an underline is input, the underline setting means causes the storage means to display a character at the indicated position of the underline. Is present. Here, if a character is stored, an underline bit is set in the character code, and if a character is not stored, a space code is inserted at that position, Since the underline bit is set in the space code, it is possible to easily draw an underline without needing to enter a space not only in a region having a character but also in a region having no character. As a result, it is possible to realize a document creation device with extremely good operability by using the underline input device of the present invention.
