Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character input device having a function of converting a kana character input into a desired character.

[0002]

2. Description of the Related Art A document creating apparatus represented by a Japanese word processor or the like displays a document on a display device such as a CRT or LCD and creates, edits, or prints the document. The document can be edited again by saving it as a file in an external storage device such as a magnetic disk and calling this file as needed.
In this way, the Japanese word processor can reuse saved documents, and it is easy to create and modify documents, so it is widely used not only for creating documents in the office but also for simple document creation at home. ing.

Creating a document with a Japanese word processor
For example, in the case of Japanese sentences containing kana-kanji characters, by performing conversion processing (hereinafter referred to as kana-kanji conversion) on kana characters input from an input device such as a keyboard, input is made based on the dictionary provided in the Japanese word processor This process repeats the process of selectively outputting and confirming conversion candidates such as words, idioms, or compound words that correspond to the Kana characters. When the file name is set and stored in a magnetic storage medium such as a floppy disk for printing, print data is output to the printer according to a predetermined menu operation.

In such a Japanese word processor,
When creating a document, you may want to enter the calculation result into the document based on a predetermined calculation formula.In such a case, usually you can check the calculation result calculated by hand calculation or calculator etc. The procedure of inputting the calculation result at a predetermined position in the document was taken.

[0005]

However, in such a conventional character input device, when a calculation result based on a predetermined calculation formula is input into a document, a numerical value is directly input from the calculation formula. Since it is not possible to do so, it was difficult to input the numerical value based on the calculation result because once the calculation result was obtained by hand calculation or a calculator etc., it was entered at a predetermined position in the document while watching the calculation result. There was a problem that it was troublesome.

Therefore, in order to facilitate the numerical input based on the calculation result, for example, there is provided a Japanese word processor having a calculator function and a function of arbitrarily calling the calculator on the screen. In this case, you can do the calculation without having a calculator at hand, but basically, the only difference is whether you perform the numerical calculation inside the Japanese word processor or outside the Japanese word processor. After the calculation, the procedure of inputting at a predetermined position in the document while looking at the calculation result remains unchanged, and the input efficiency in numerical value input based on the calculation result is not improved so much.

Further, regarding the tabulated document contents,
Some are provided with a simple spreadsheet function that allows you to enter the calculation results for the characters that have already been input, but in this case, the calculation input is performed only in the tabulated document, and the calculation results are also calculated in advance. Since the input position of was determined, it was not possible to input only the calculation result to any position in the document.

An object of the present invention is to input an operation result corresponding to an input operation expression to an arbitrary position in a document by an operation similar to the kana-kanji conversion.

[0009]

The means of the present invention are as follows.

According to the present invention, an input means for inputting a predetermined character string, a storage means for storing the character string input by the input means, and a character stored in the storage means when a conversion process is instructed. Discriminating means for discriminating whether or not the column is an arithmetic expression, and a candidate for outputting the arithmetic result of the arithmetic expression as a conversion candidate in the conversion processing when the character string is discriminated by the judging means as the arithmetic expression. And an output unit.

[0011]

The operation of the means of the present invention is as follows.

According to the present invention, when the conversion processing is instructed for the character string input by the input means, the determining means determines whether the character string stored in the storage means is an arithmetic expression. If it is determined that this character string is an arithmetic expression, the candidate output means outputs the arithmetic result of the arithmetic expression as a conversion candidate in the conversion processing.

That is, the operation result in the arithmetic expression is output as a conversion candidate by the same operation as the conversion operation of the kana input at the time of converting kana-kanji, and the operation similar to the confirmation of the conversion candidate is performed.
The calculation result corresponding to the input calculation expression is input at an arbitrary position in the document.

EXAMPLES Examples will be described below with reference to FIGS.

1 to 4 are views showing an embodiment of a character input device according to the present invention.

First, the structure will be described. FIG. 1 is a block diagram showing the main configuration of the character input device of this embodiment. In FIG. 1, the character input device 1 includes a CPU 2, a dictionary 3, a candidate buffer 4, an arithmetic expression analysis unit 5, a display device 6, a keyboard 7, a ROM 8, an input buffer 9, and an arithmetic unit 10.

The CPU 2 controls the entire character input device 1 based on the program code stored in the ROM 8.

The dictionary 3 is dictionary data for Kana-Kanji conversion, and includes, for example, a system dictionary in which basic words are registered in advance, a user dictionary in which the user independently registers words, and external characters created by the user. It is configured.

The candidate buffer 4 temporarily stores a conversion candidate group at the time of converting Kanji characters.

The arithmetic expression analysis unit 5 checks the syntax stored in the input buffer 9 as an arithmetic expression that can be executed by the arithmetic unit 10,
It is to determine whether the character string is an arithmetic expression. The syntax in this embodiment is, for example, BAS.
The syntax in high-level languages such as IC programs is applied as it is.

The display device 6 is composed of an LCD, a CRT, etc., and displays alphanumeric kana input characters input from the keyboard 7, kana-kanji converted kanji characters and the like.

The keyboard 7 is for inputting alphanumeric and kana character data, instructing Kanji conversion, and specifying various functions for document processing by key input.

The ROM 8 stores programs for various control processes executed by the CPU 2.

The input buffer 9 stores alphanumeric kana character data input from the keyboard 7 as an input character string for kana-kanji conversion.

When the arithmetic analysis unit 5 determines that the character string stored in the input buffer 9 is an arithmetic expression, the arithmetic unit 10 actually performs an operation according to the arithmetic expression of the character string. . Next, the operation of this embodiment will be described.

Kana-Kanji conversion processing when a character including an arithmetic expression is input will be described with reference to the flowchart of FIG.

FIG. 2 is a flow chart for explaining an operation example of this embodiment.

In the following explanation of the operation, consider a case where the kana-kanji conversion processing instruction operation is performed after the character string "2 × 3" is input from the keyboard 7.

First, when Kana-Kanji conversion processing is executed, R
The CPU 2 activates the arithmetic expression analysis unit 7 based on the program stored in the OM 8 (step S1), and determines whether the input character string (in this case, “2 × 3”) is an arithmetic expression ( Step S2).

If it is determined that the expression is not an arithmetic expression,
Ordinary kana-kanji conversion processing using only the dictionary 3 is performed (step S3). On the other hand, when it is determined that it is an arithmetic expression, the arithmetic unit 10 calculates an arithmetic result corresponding to the arithmetic expression (step S4).

In this case, since "2x3" is an arithmetic expression, the arithmetic unit 10 characterizes the operation result of "2x3", that is, "6" (step S5). The selected "6" is stored in the candidate buffer 4 (step S6), and the input character string itself is also stored in the candidate buffer 4 (step S7).

At this point, the candidate buffer 4 stores "6" and "2 × 3", as shown in FIG.

In the subsequent processing, candidates are displayed based on the data in the candidate buffer 4 (step S8).

FIG. 4 is a diagram showing a display example when converting the arithmetic expression in FIG. 2 into kana-kanji.

That is, when “2 × 3” is input from the keyboard 7, “2 × 3” is displayed on the display device 6 as shown in FIG. 4 (a).

When the kana-kanji conversion processing is instructed to be executed from the keyboard 7, "6" is first displayed on the display device 6 based on the data in the candidate buffer 4, as shown in FIG. 4 (b). When it is displayed and the Kana-Kanji conversion processing is instructed again from the keyboard 7, based on the data in the candidate buffer 4, as shown in FIG.
3 ”is displayed on the display device 6.

Thereafter, each time the kana-kanji conversion process is executed, the data in the candidate buffer 4, in this case, "6" and "2 × 3" are alternately displayed on the display device 6.

As described above, in the present embodiment, when the calculation result of the calculation expression is input at an arbitrary position in the document, when the calculation expression is input and the kana-kanji conversion is executed, the input calculation is performed. The calculation result obtained by calculating the expression is output as a candidate as conversion data.

Therefore, the operation result of the operation expression can be input by the same operation as the normal Kana-Kanji conversion.
It is possible to save the trouble of inputting after separately calculating and improving the efficiency of document creation.

In the above embodiment, the operation is basically described on the premise that one phrase is input. However, if it has a multi-phrase conversion function, the input character string is divided into phrases. After that, if you repeat the above process for each phrase,
Similar processing results can be obtained.

In the above embodiment, a simple multiplication is taken as an example of the operation, but the operation executed by the operation unit 10 is, for example, a trigonometric function, a remainder calculation, or the like. Not only calculation but logical operation is included.

[0042]

According to the present invention, when a conversion process is instructed for a character string input by the input means, it is determined whether the character string stored in the storage means is an arithmetic expression, and the character When the column is determined to be an arithmetic expression, the calculation result of the arithmetic expression is output as a conversion candidate in the conversion process.

Therefore, the operation result in the arithmetic expression can be output as the conversion candidate by the same operation as the conversion operation of the kana input when converting the kana-kanji character, and the operation corresponding to the input arithmetic expression can be performed by the same operation as the confirmation of the conversion candidate. You can enter the result anywhere in the document.
