BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control device for displaying input data of a computer or the like, and more particularly to a plurality of display devices input from input means in a display area having a preset width of the display device. The present invention relates to a display control device that displays a character string of characters.

[0002]

2. Description of the Related Art Generally, a display control device for displaying a character string corresponding to input data such as a computer may have a display area for the character string corresponding to the input data set in advance. In this case, this display area is configured to be preset with a certain width by a so-called default function, for example, 22 characters per line.

By the way, when the area for displaying the data is set in advance and the width of the display area is set to a certain width by the default function or the like, the character string corresponding to the input data is set. If the length of is longer than the width of the display area set by the default function, the character string corresponding to the input data cannot be displayed in this display area. Therefore, in this case, an input error occurs when the length of the character string corresponding to the input data exceeds the width of the display area, and it becomes impossible to input more data.

Therefore, in the conventional display control device,
In this case, shift the character string displayed in the display area to the left by the required number of characters so that new data can be input, or input of this data is temporarily stopped and this display area It was configured to perform another enlargement operation of the display area to increase the width or height, and then re-enter the data.

[0005]

However, in the configuration in which the character string displayed in the display area is shifted to the left, the character at the left end is sequentially erased by this shift processing, so that it corresponds to the input data. It is not possible to display the entire character string to be displayed, and in the configuration for enlarging the display area, the enlarging operation of the display area is very troublesome, and a device having this type of display unit is provided. Therefore, the operability of the device is deteriorated, and the working efficiency using the device having the display unit of this kind is deteriorated.

Therefore, the present invention improves the operability of a device having a display device for displaying a character string consisting of a plurality of characters input from the input means in a display area having a predetermined width set in advance, It is an object of the present invention to provide a display control device with a large improvement in work efficiency.

[0007]

In order to achieve the above object, the present invention provides a character string consisting of a plurality of characters input from an input means in a display area of a display means having a preset width. In the display control device for displaying, when inputting a new character to the display area from the input means, the length of a new character string formed by the input of the new character is compared with the width of the display area. And a display control means for automatically enlarging the width or height of the display area by one character when the length of the new character string is larger than the width of the display area.

[0008]

According to the present invention, when a new character is input to the display area from the input means, the length of a new character string formed by the input of the new character is compared with the width of the display area, When the length of the new character string is larger than the width of the display area, the display control means automatically enlarges the width or height of the display area by one character.

FIG. 2A shows an example of a display screen displayed by the display device 50 shown in FIG. A window 501a having a predetermined size is displayed in the display screen 501 shown in FIG. 2A, and a data display area 501b is displayed in the window 501a. The data display area 501b is preset to a predetermined size, in this case 6 characters per line, by the default function of the display control device.

In this state, consider a case where a predetermined character string is input into the data display area 501b from the input section 40 shown in FIG.

For example, in the data display area 501b from the input section 40 shown in FIG. 1, "My name is Yamada"
Suppose you try to input a character string of 10 characters in one line. In this case, the size of the data display area 501b of the display screen 501 shown in FIG. 2 (a) is preset to one line of six characters by the default function of this display control device. Therefore, "My name is Yamada When a character string of 6 characters and 1 line up to ““ My name ”” is input from the input unit 40 in the character string of 10 characters and 1 line, the data display area 5
01b will be full, and it will not be possible to enter the remaining character string of “Eha Yamada” consisting of four characters and one line. This state is shown in FIG.

By the way, in this embodiment, when a new character is input from the input section 40 to the data display area 501b, the length of a new character string formed by the input of the new character and the data display. The width of the area 501b, that is, one line of six characters in this case is compared, and if the length of the new character string is larger than the width of the display area, the data is controlled by the central processing unit (CPU) 10. The width of the display area of the display area 501b is automatically expanded by one character.

Therefore, when the data display area 501b becomes full as shown in FIG. 2 (b), the width of the data display area 501b shown in FIG. 2 (b) becomes 1 as shown in FIG. 2 (c). The data display area 501c is automatically enlarged by the character, and the next character "e" is displayed in this data display area 501c.

Thereafter, this operation is repeated three times, and the width of the data display area 501c is automatically expanded by one character for each operation, and as a result, the data display of one line of six characters shown in FIG. 2A is performed. The area 501b is enlarged to a data display area 501d of 10 characters and 1 line as shown in FIG. 2D, and a character string "My name is Yamada" of a desired 10 characters and 1 row is expanded to this enlarged data display area. It is displayed in 501d.

In the above embodiment, when the data display area 501b is filled with the character string input from the input section 40, the width of the data display area 501b is automatically expanded. When the area 501b is filled with the character string input from the input unit 40, the height of the data display area 501b, not the width thereof, that is, the line may be enlarged by one character (one line at a time). .
