Abstract

PURPOSE:To improve the efficiency of an input operation and to minimize the number of the times of the character input of an operator especially. CONSTITUTION:The device has a character input part 1 to perform the character input, a left parenthesis mark deciding part 2 to decide whether or not the input character from the character input part 1 is the left parenthesis mark, and a right parenthesis mark output part 4 to output the right parenthesis mark corresponding by the decided result of the deciding part 2. The character inputted subsequently is inserted before the right parenthesis mark by a character inserting part 5. Further, the data from the left parenthesis mark deciding part 2 and the corresponding right parenthesis mark output part 4 are synthesized and stored in an input character storing part 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character input device such as a computer system, and more particularly to a character input device such as a keyboard.

[0002]

2. Description of the Related Art Conventionally, this type of character input device is used for inputting characters in a computer system or the like. In addition, it is required that the number of character inputs by the operator be reduced. For example, when the left parenthesis symbol is input and the characters and the like are finished, the right parenthesis symbol must be input eventually. In such a case, as for the parenthesis symbol by keyboard input, it is required to press the shift key and the corresponding parenthesis symbol, and the number of times of pressing increases compared with the input of characters. In short, in the conventional character input device, the operator is forced to input the right bracket symbol.

[0003]

In the above-described conventional character input device, not only the operator inputs the left bracket symbol but also the right bracket symbol, so that the number of character inputs increases. There is.

An object of the present invention is to provide a character input device that automates the input of such a right parenthesis symbol and reduces the number of times of character input.

[0005]

A character input device of the present invention comprises a character input section for inputting characters, and a left parenthesis symbol determination section for determining whether or not an input character from the character input section is a left parenthesis symbol. If the left parenthesis symbol is a left parenthesis symbol according to the result determined by the left parenthesis symbol determination unit, the corresponding right parenthesis symbol output unit outputs the corresponding right parenthesis symbol, and the characters input thereafter are in a state of being input before the right parenthesis symbol. And an input character storage unit that stores information from the left parenthesis symbol determination unit and the corresponding right parenthesis symbol output unit.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of a character input device showing an embodiment of the present invention. As shown in FIG. 1, in this embodiment, when the operator or the like first inputs one character using the character input unit 1, the left bracket symbol determination unit 2 determines whether or not it is a left parenthesis symbol. As a result, when it is determined that the symbol is a left parenthesis symbol, the right parenthesis symbol corresponding to the left parenthesis symbol input by the corresponding right parenthesis symbol output unit 4 is output. The output right parenthesis symbol is put in the character input state by the character insertion unit 5 so that the input character is inserted before the right parenthesis symbol. Characters input from the character input unit 1 via the determination unit 2 are stored in the input character storage unit 3 together with the data from the output unit 4.

When the input of the right parenthesis symbol is requested, the operator moves the character input position to the position next to the left parenthesis symbol which has been input by the cursor key or the like, and the character insertion unit 5
To cancel.

FIG. 2 is an operation flow chart of the character input device in FIG. As shown in FIG. 2, first, S1 is a character input step by the operator, and next S2 is a determination step of determining whether or not the character is a left bracket symbol. YE here
If it is S, the process proceeds to a right parenthesis output step S3 for outputting the right parenthesis symbol corresponding to the left parenthesis symbol, and then a character insertion state step S4 for putting the character input into the insertion state and an input character storage for storing the input character. Step S5 is performed.
On the other hand, if NO in step S2, the process proceeds to input character storage step S5 for storing character input and waits for character input.

FIG. 3 is a block diagram of a character input device showing another embodiment of the present invention. As shown in FIG. 3, in this embodiment, the determination unit 2 and the corresponding right parenthesis symbol output unit 4 in the one embodiment of FIG. This is because the specific character determining unit 6 for determining a specific character and the corresponding specific character determining unit 7 corresponding to the specific character are replaced. Others are the same.

[0011]

As described above, in the character input device of the present invention, when the left side of a parenthesis symbol or the like is input, the right side parenthesis symbol is automatically created, so that the number of times of character input by the operator can be reduced. The effect is that it can be reduced.

Claims (1)

[Claims] 1. A character input section for inputting characters, a left parenthesis symbol determination section for determining whether an input character from the character input section is a left parenthesis symbol, and a result determined by the left parenthesis symbol determination section. If it is a left parenthesis symbol, a right parenthesis symbol output unit that outputs the corresponding right parenthesis symbol, a character insertion unit that makes the characters to be input subsequently input before the right parenthesis symbol, and the left parenthesis symbol determination unit And an input character storage unit for storing information from the corresponding right parenthesis symbol output unit.
