Abstract

PROBLEM TO BE SOLVED: To input and display a closing parenthesis at an arbitrary position being conscious of closing parenthesis corresponding to an opening parenthesis at the time of document preparation. SOLUTION: When a key input is the opening parenthesis, a key decision part 4 supplies this key input to a key input processing part 5 to display it on a screen, and retrieves the closing parenthesis corresponding to the opening parenthesis from a parenthesis corresponding data part 1 and saves the closing parenthesis in a closing parenthesis stack part 3. Then when there is a key input, the key decision part 4 decides whether or not this key input is a specified function key input, and takes the closing parenthesis out of the closing parenthesis stack part 3 and supplies it as a key input to the key input processing part 5 when the key input is the specified function key input. The key input processing part 5 performs an input process and displays the closing parenthesis on the screen.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for creating sentences in response to keyboard input, and more particularly to a device for automatically inputting symbols (for example, parentheses) used in pairs.

[0002]

2. Description of the Related Art Generally, in an OA device such as a word processor and a personal computer, when a sentence is expressed using parenthesis symbols such as "{" and "}", an opening parenthesis "{, (, [" etc. is entered. After that, closing brackets are input corresponding to these opening brackets.

In such a case, it is necessary for the operator to consciously input the closing parenthesis, and in the OA equipment and the like, generally, the inputting of the parentheses is an input method of pressing a plurality of keys at the same time. Operability is poor when inputting closing brackets.

As a device for improving the operability described above, a device for automatically inputting opening brackets "{, (, [", etc., and at the same time, closing brackets corresponding to the opening brackets, allowing a sentence to be entered in the brackets. Are known (for example, Japanese Laid-Open Patent Publication No. 2-
85954 issue).

Now, with reference to FIG. 3, parenthesis symbol input processing in a conventional document creating apparatus (for example, a word processor) will be described.

In this apparatus, for example, when "{" is input as a parenthesis symbol from the keyboard (step S1), "{" is first displayed on the display section (step S2). At this time, the bracket symbol correspondence table is searched (step S
3) The corresponding bracket symbol "}" is extracted (step S4). Then, "}" is displayed on the display unit (step S5). Then, a cursor is set between the inter-bracket symbol insertion mode symbols (step S6). In other words, "{ } ”Is displayed.

When a character is input with the cursor position kept unchanged (steps S7 and S8), it is determined that the character is inserted and the character is input and "{ }] Is inserted (step S9). For example, if you leave the cursor at the same position and enter "A" from the keyboard, "{A }] ”Is displayed.

On the other hand, when the character is input by moving the cursor outside the parenthesis symbols, it is determined that the insertion has been completed (step S10), and the input character is displayed outside the parenthesis symbols. For example, "{a }] Is displayed, move the cursor to After that, click "I" from the keyboard.
When you enter, "{A} Is displayed.

[0009]

As described above, in the conventional document creating apparatus, the closing parenthesis is displayed at the same time when the opening parenthesis is input, so that the operability at the time of creating the document is improved, but the parenthesis input is performed. If you do, the closing bracket will always be entered, so if you want to add a bracket to a sentence that has already been created, delete the closing bracket that was displayed and enter it at the position you want to insert. The operation to fix is necessary. That is, there is a problem that unnecessary operations increase.

That is, since the closing parenthesis is displayed at the same time when the opening parenthesis is input, the position of the closing parenthesis cannot be arbitrarily specified, and thus the operability when correcting the prepared sentence is poor. There is a point.

An object of the present invention is to provide a document creating apparatus which has good operability when inputting characters including parentheses.

[0012]

According to the present invention, there is provided a document creating apparatus for displaying a sentence on a screen in response to a key input from a keyboard, wherein a key designated in advance among the key inputs is used. The input is set as a designated function key input, and when the key input is received, it is determined whether the key input is an open parenthesis and if it is an open parenthesis, the close parenthesis corresponding to the open parenthesis is temporarily held. There is provided a document creating apparatus characterized by further comprising a determination processing means which holds the closing parenthesis as the closing parenthesis and displays the holding closing parenthesis on the screen when the key input is the designated function key input.

Further, the document creating apparatus includes a setting table in which a key corresponding to the designated function key input is set as a designated function key, and the opening parenthesis and the closing parenthesis corresponding to the opening parenthesis are paired. It has a data section corresponding to parentheses stored in.

The determination processing means may be, for example, a key determination unit that determines whether the key input is the designated function key or the key input is the open parenthesis, and the key input is the open parenthesis. And a stack portion on which the closing parenthesis corresponding to the opening parenthesis is stacked, and the key input is the opening parenthesis, the key determining unit retrieves the parenthesis data corresponding data portion and detects the closing parenthesis. Stacked as the holding closing bracket in the stack part,
When the key input is the designated function key,
The holding closing bracket is taken out from the stack portion. The stack unit is, for example, a first-in-first-out memory.

When inputting a sentence including parentheses, the closing parenthesis corresponding to the opening parenthesis is saved from the parenthesis corresponding data section to the stack section. After that, when the designated function key is input, the closing parenthesis is read from the stack portion according to this input and displayed on the screen. Therefore, the operator can input and display the closing parenthesis at an arbitrary position on the screen without being aware of the corresponding opening parenthesis, and the operability can be improved.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

Referring to FIG. 1, the document creating apparatus according to the present invention is, for example, a word processor. This document creation device includes a parenthesis correspondence data section 1, a designated function key setting area 2, a closing parenthesis stack section 3, a key determination section 4, and a key input processing section 5.

Data relating to the opening parenthesis and the closing parenthesis is stored in the parenthesis corresponding data section 1, and when inputting characters,
It is a table in which parentheses that form a pair (pair) are set.

The designated function key setting area 2 is an area for setting a key for automatically inputting a closing bracket.

The closing parenthesis stacking section 3 is a stacking section for saving the closing parenthesis for the input parenthesis until a request comes. The stack unit 3 manages the stock after the first-in.

The key determination unit 4 determines whether or not the data input by the key is the data stored in the bracket corresponding data unit 1. Then, if it is the corresponding opening bracket, the key determination unit 4 saves the data of the closing bracket corresponding to the opening bracket in the closing bracket stack unit 3. When the key input is the designated function key, the key determination unit 4 performs a process of passing the characters saved in the closing bracket stack unit 3 to the key input processing unit 5 as input data.

The key input processing unit 5 inputs the characters sent from the key determination unit 4 and displays them on the screen.

Next, the operation of the document creating apparatus shown in FIG. 1 will be described with reference to FIG.

When there is a key input from the keyboard 1a (step A1), the key determination section 4 determines whether the key input data is a function key set in the designated function key setting area 2 in advance (step A1). A2). If the key input data is not the designated function key, then the key determination unit 4 determines whether the key input data is the data stored in the bracket corresponding data unit 1 (step A3). As a result, if the key input is not the data stored in the bracket-corresponding data section 1, the key determination section 4
Passes the key input to the key input processing unit 5. The key input processing unit 5 processes the key input and displays it on the screen of a display unit (not shown).

On the other hand, in step A2, if the key input is a function key, the key determination section 4 extracts stack data from the closing bracket stack section 3 in response to the function key input, as will be described later (step A4). , And passes it as key input data to the key input processing unit 5 (step A5).

In step A3, if the key input data is the data (open parenthesis data) stored in the parenthesis corresponding data section 1, the key determination section 4 searches for the closing parenthesis data corresponding to the open parenthesis data ( In step A6), the closing bracket data is saved from the corresponding parenthesis data section 1 to the closing bracket stack section 3 (step A7).

After that, in step A2, when the function key set in the designated function key setting area 2 is input from the keyboard 1a, the key determination section 4 causes the closing bracket stack section 3 to input stack data in response to the function key input. Is taken out and passed to the key input processing section 5 as key input data. Then, the key input processing unit 5 processes the key input data and displays it on the screen (display unit: not shown).

More specifically, now, "measurement (formula)"
Enter the sentence "XX (Y + Z)".

First, "measurement" and "constant" are input. These characters are regarded by the key determination unit 4 as neither designated function keys nor parentheses, and are passed to the key input processing unit 5 as they are. Next, "(" is input. Key determination unit 4
Determines whether it is the designated function key or the parenthesis stored in the parenthesis correspondence data part 1.

Here, it is determined that the input character "(" is a character stored in the parenthesis corresponding data section 1 and the closing parenthesis ")" corresponding to "(" is from the parenthesis corresponding data section 1 to the closing parenthesis stack 3 Is set to.

The input character "(" is passed from the key determination unit 4 to the key input processing unit 5 and a normal key input process is performed, and as a result, "measurement (" is displayed on the screen.

Next, the "expression" is input. The "expression" is also determined by the key determination unit 4, and as a result, a normal key input process is performed, and "measurement (expression)" is displayed on the screen.

When entering the last ")", the operator presses a predetermined function key. The key determination unit 4 checks whether or not the function key is a designated function key. In this case, because it is the specified key,
The key determination unit 4 takes out the designated data from the closing bracket stack unit 3 and passes the taken-out data “)” to the key input processing unit 1 as a key input. As a result, the "measurement (formula)" is input.

Next, "" is input. As described above, the key determination unit 4 checks whether the function key is a designated function key or a parenthesis. Since "" is regarded as an open parenthesis, """is set in the closing parenthesis stack unit 3.

After inputting "X" and "x", "(" is checked in the same manner, and ")" is set in the closing bracket stack section 3. When the designated function key is pressed after inputting “Y”, “+”, and “Z”, the closing parenthesis stack unit 3 is set to the closing parenthesis stack unit 3 because the first-in first-out management is performed as described above. ")" Is extracted, and the extracted data ")" is passed from the key determination unit 4 to the key input processing unit 1 as a key input. Then, when the designated function key is pressed again, """set in the closing bracket stack section 3 is taken out, and the taken-out data""" is passed from the key determination section 4 to the key input processing section 1 as a key input. .

In this way, when the closing bracket is input, the closing bracket corresponding to the opening bracket can be input by simply pressing the designated function key, and the operability is improved.

Furthermore, even for sentences that have already been created,
The present invention can be applied.

Now, "This is a measurement (formula)" X × (Y +
Z) ”,” in the sentence “measurement (formula)
To close "XX (Y + Z)" with "[" and "]", first enter "[" at the position where you want to insert the opening bracket (move the cursor to the position where you want to insert the opening bracket). To do. As a result, “This is in the measurement (formula)“ X × (Y + Z) ”is displayed on the screen.
Then, as described above, by inputting the opening bracket "[", "]" is set in the closing bracket stack unit 3.

Thereafter, when the function key is pressed at the position where the closing bracket is desired to be inserted ((the cursor is moved to the position where the opening bracket is desired to be inserted), the closing bracket "]" is key-input and the key is judged from the key determination section 4. It is passed to the input processing unit 5, and on the screen, "This is [measurement (formula)
“X × (Y + Z)”] is displayed. That is, the text can be easily corrected.

[0040]

As described above, according to the present invention, the input of the closing parenthesis corresponding to the opening parenthesis can be input by pressing the designated function key, so that the error in the closing parenthesis input is eliminated and the operability is improved. There is. In other words, it is determined whether or not the opening parenthesis is input, the closing parenthesis corresponding to the input opening parenthesis is saved in the stack, and the saved data is displayed as the key input data only by pressing the function key. Therefore, there is an effect that the error in the closing bracket input is eliminated and the operability is improved.
