Abstract

PURPOSE:To realize a calculating function to an input device provided with a calculating function through a simple operation by adding a calculating function to an input device provided with no calculating function. CONSTITUTION:A character kind analyzing section 11 analyzes the kind of inputted characters, whether the characters are KANA (Japanese syllabary) or alphanumeric characters, and, when the characters are discriminated as KANA characters, outputs the characters to a dictionary accessing section 12. When the characters are discriminated as alphanumeric characters, the section 11 outputs the characters to a calculation processing section 13. The section 12 makes access to a dictionary based on the inputted KANA (characters and executes KANA-KANJI (Chinese character) conversion. After conversion, the section 11 sends the converted results to a candidate group producing and processing section 14. On the other hand, the section 13 analyzes the inputted alphanumeric characters and executes the calculation of numerals or calculation of a function expressed by the characters by respectively using calculation routines and outputs the calculated results to the processing section 14. The section 14 produces plural groups of candidates by grouping the plural candidates outputted from the sections 12 and 13 and outputs the results to a display processing section 15.

Description

[Detailed Description of the Invention] [Summary] Regarding character input devices equipped with a kana-kanji conversion function such as a Japanese word processor, this input device provides a calculation function to an input device that does not have a calculation function, and has a total of 37 functions. 19.The device also has a calculation function in the front car. The purpose is to provide a human-powered device with a calculation function that can be realized in a computer, and it identifies whether the input characters are kana characters or alphanumeric characters, and outputs the kana characters to the dictionary access part and the alphanumeric characters to the calculation processing part. a dictionary access unit that accesses a dictionary and outputs candidate conversion characters for input alphanumeric characters and kana characters;
A calculation processing section that performs calculation processing expressed by input alphanumeric characters and outputs the calculation results, a candidate group creation processing section that creates each output from the dictionary access section and the calculation processing section as a candidate group, and a candidate group creation processing section. The display processing unit is configured to include a display processing unit that performs a process of displaying an output from the processing unit.

[Industrial Field of Application] The present invention relates to a character input device, such as a Japanese word processor, having a kana-kanji conversion function.

In recent years, Japanese word processors and workstations equipped with Japanese processing functions have become widely used, and characters input from the keyboard are converted into kanji-converted sentences using the kana-kanji conversion function. Input is being made.

Input devices that use Kana-Kanji fiAa function, such as Japanese word processors, usually do not support calculation functions (functions that calculate calculation expressions or function expressions expressed by input character strings). It was necessary to perform calculations corresponding to calculation formulas and function formulas using a desktop calculator or mental arithmetic.

In addition, there is a way to implement the calculation function by an application (program), but in that case, in order to provide a common kana-kanji conversion environment for each application, the kana-kanji conversion is performed in memory independently of the software (application software) that uses it. Therefore, when the Kana-Kanji conversion process starts, input from an input device (keyboard, etc.) is occupied by the Kana-Kanji conversion process until the conversion process is completed, and the Kana-Kanji conversion process is used to determine the character string of the converted word. Unless the kana-kanji conversion process is completed, the process will not return to the running software (application).

For this reason, even in software that supports calculation functions, if Japanese input and calculation processing are mixed, operations to start and stop the kana-kanji conversion process will occur, complicating the work. It is desired that calculation processing functions can be realized with simple operations.

[Conventional technology] A configuration diagram of a conventional example is shown in FIG.

In FIG. 5, 60 is a human-powered device such as a keyboard;
1 is a switching device, 62 is a character processing section consisting of software and hardware including an ephemeral-kanji conversion function, 63 is an ephemeral-kanji conversion section, and 64 is an application (program).
, 65 is a calculation processing unit included in the application, 66
represents a display device.

To explain the operation of the conventional example, when the switching device 61 is switched from the normal operation to the execution state of the kana-kanji conversion operation, the character string input from the input device 60 is converted to the kana-kanji conversion section 63 via the switching device 61. If the Kana-Kanji conversion dictionary (not shown) is occupied and there is a Kana-Kanji conversion dictionary (not shown), Kana-Kanji conversion is performed.In that case, if there are multiple candidate characters, do you display multiple candidates at the same time and select one by inputting the selection? ,
Alternatively, there is a method in which only one candidate conversion character is displayed, and the next candidate is sequentially displayed and determined by operating a conversion key.

When performing a manual calculation that requires calculation from the input device 60, the state of the switching device 61 is switched in accordance with an instruction from the input device. Then, the calculation character string inputted from the input device 60 is manually input to the calculation processing section 65 of the application 64, and when the calculation processing function executes the calculation γ, the calculation result is displayed on the display device 66.

[The problem that the invention attempts to solve! i! ] In the above-mentioned conventional input device, character input for kana-kanji conversion and character input for calculation processing are cut off in advance.
It is necessary to clearly differentiate by operating the A device, and even in software that supports calculation processing, if Japanese input and calculation processing are mixed, the operation to start and end the kana-kanji conversion processing is necessary. occurs, complicating operations.

An object of the present invention is to provide a calculation function capable of providing calculation functions to applications that do not have calculation functions, and to provide calculation functions to applications that do have calculation functions with simple operations. do.

[Means to solve the problem] FIG. 1 is a diagram showing the basic configuration of the present invention.

11 in FIG. 1 is a character type analysis section, 12 is a dictionary access section,
13 is a calculation processing section, 14 is a candidate group creation processing section, and 15 is a display processing section.

The present invention selects alphanumeric characters from input characters, executes calculation corresponding to the calculation formula or function formula expressed by the alphanumeric characters in the calculation processing unit, and converts the result of the calculation and the converted character string using a dictionary. It is also displayed as a candidate character.

[Operation] The character type analysis section 11 in FIG. If it is identified as an alphanumeric character, it is output to the calculation processing section 13. Note that the alphanumeric character string is also supplied to the candidate group creation processing section 14 as a candidate via the calculation processing section 13 or the dictionary access section 12.

The dictionary access unit 12 accesses the dictionary based on the input kana characters, performs kana-kanji conversion, and outputs the conversion results to the candidate group creation processing unit 14. When a plurality of conversion results are obtained through this kana-kanji conversion, each of them is output as a candidate.

When alphanumeric characters are input, the calculation processing unit 13 analyzes the alphanumeric characters, calculates the expressed numerical value or calculates the function using each calculation routine, and sends the results to the candidate group creation processing unit. Output to 14.

The candidate group creation processing unit 14 creates a plurality of groups of candidates by grouping the plurality of candidates (including alphanumeric character strings) output from the dictionary access unit 12 and the calculation processing unit 13. The results are output to the display processing section 15.

The display processing unit 15 converts the plurality of input candidate tilt groups into a display format, and outputs it to a display device (not shown).

In this way, the calculation results are displayed as candidates in the same way as the results of kanji conversion, so there is no need for complicated operations between the user and the user. All you have to do is make a mock selection of a candidate (each time you press the conversion key, a different candidate is displayed, and you can choose from among them).

In addition, when a calculation formula is input, the calculation result is not always needed, so if the input string is the first candidate and the calculation result is the second candidate, the user will not need the calculation result. In this case, the desired character input can be realized by selecting the second Ia +iIi.

[Example] FIG. 2 is a processing flow diagram of an embodiment of the present invention.

Figure 3 is a detailed flow diagram of character type identification processing, Figure 4 (a)
and FIG. 4 (bl is a detailed flow diagram of calculation processing).

In FIG. 2, when the process is started and a key is manually operated from the keyboard (step 20), it is determined whether the key manually is an input of the [conversion] key (step 21). If not, then it is determined whether it is the [Enter] key or not, and if it is not the [Enter] key, the key force is stored in the input buffer (step 23).

When the [Convert] key is pressed after multiple character strings have been stored in the input buffer in this way, the process moves from step 21 to step 25, and the process checks whether the [convert] key is input for the first time. If it is the first time, a process is performed to identify the character type of the input buffer in which the character string entered manually from the keyboard is stored (step 2G).

Next, step 27) identifies whether the character string is alphanumeric or not.
In the case of alphanumeric characters, the alphanumeric character string is first held as a candidate (step 32), and then calculation processing is performed on the alphanumeric characters (step 33); if the identified character string is not alphanumeric, dictionary access processing is performed. If a large number of candidates are obtained at this time, they are ranked and selected as candidates, similar to a conventional word processor.

The plurality of candidates obtained from the dictionary, the calculation results from the calculation process, and the alphanumeric character strings are each combined as a candidate group in the next step 29, and further, in step 30, an operation for displaying the candidate group is executed. Various methods can be used as the display method in this case.

In this example, the input character string (including alphanumeric characters) is simply converted into kana-kanji, one result is displayed (when there are multiple results of kana-kanji conversion), and the second candidate is displayed as a result of alphanumeric characters. The result of executing a calculation formula or function calculation is retained, and candidates can be switched by operating [Convert]. If you want to select the candidate by looking at the displayed content, press the [Enter] key. One candidate displayed from among the candidate group can be input.

In addition to the above methods, when a large number of candidates are generated as a result of Kana-Kanji conversion, conventional word processors employ methods such as displaying multiple candidates at the same time and selecting one of them using number keys or function keys. Other methods can be used.

Figure 3 shows steps 26 and 28 of the process flow in Figure 2 above.
It is a figure which shows the example of the detailed flow of the character type umbrella identification process performed in .

In FIG. 3, one character is taken out from the cover sofa (step 260), it is determined whether the character is an alphanumeric character or not (step 261), and if it is an alphanumeric character, the character is stored in an alphanumeric character string area of the memory (not shown). (step 262), then determines whether the previous character is an alphanumeric character (step 263) Next, determines whether the previous character is an alphanumeric character, and if it is a kana character, this character is an alphanumeric character. In order to perform the kana-kanji conversion process on the kana character string for which the input was completed one character before, a kana character string area (not shown) is designated and the process of step 28 in FIG. 2 is activated.

On the other hand, if alphanumeric characters are input continuously, step 26
By processing 0 to 263, alphanumeric character strings are sequentially stored in the alphanumeric character string area. When the alphanumeric character string ends and the beginning of the kana characters (Japanese characters) is extracted, step 26
1, the character is determined as No, and in step 264 the character is stored in the kana character string area of the memory. N because it's a number.

Then, the process moves to step 267. Here, the process of step 32 in FIG. 2 is activated using the alphanumeric character string area in which the alphanumeric characters have been previously stored.

In this way, the character type of the character string is identified, whether it is an alphanumeric character string or a kana character string, and processing is performed in accordance with the respective recognition results.

Figure 4 fat and Figure 4 fbl are shown in step 3 of Figure 2.
3 is a diagram illustrating an example of a detailed flow of calculation processing executed in Step 3. FIG.

There are two types of calculations performed by the calculation function of this embodiment: Go gamma arithmetic operations and functional calculations. Enter. The usable operators and their priorities are as follows, and blanks cannot be inserted in the middle of an arithmetic expression.

()>”, △>*, /, %〉+.

(However, > represents the priority relationship) Moreover, the functional calculation is already described in the following format.

Function name (calculation formula) Arithmetic operation formulas and function formulas can be already described in the calculation formula, and in this embodiment, the following character strings are used as function names.

(However, the log function specifies two total 3γ2 separated by a comma in parentheses) abs, ewp, In, l
ogIO, 5qrL+ log, sin, cos.

Lan, asin, ncos, ataL ata
n2 To explain the detailed flowchart of the calculation process based on such a premise, in step 400 of FIG. 4 (8), an alphanumeric character string (the character string stored in the area specified by step 267 of FIG. The result of the analysis is identified by the determination process in step 400 and below. First, determine whether all of them are numeric character strings, and then select YES.
Then perform numeric-kanji conversion (steps 401, 402)
), if they are not all numeric character strings, then determine whether the character string is "today", and if YES, set today's date (steps 403, 405). If No in step 403, determine whether the character string is "now". If YES, read the clock data representing the time and set the current time (steps 405, 406); if NO in step 405, determine whether the character string is one of the four arithmetic operations (addition, subtraction, multiplication, division);
If ES, execute the corresponding calculation, and if NO in step 407.
If it is determined that it is a function calculation, it is determined whether it is a function calculation, and if NO, any calculation is performed.
Similar to the process of 04.406.408, the process returns to the end position of the calculation process.

If it is a function calculation (YES in step 409), it is sequentially determined whether or not it is an individual function in each step including step 410 and FIG. Calculation is performed using a function calculation routine to perform the calculation, and when the calculation is completed or NO is determined in step 433 (also in this case, calculation (do not execute γ))
, returns to the end position of the calculation process (indicated by 1?ET).

Next, the operation of a specific example of a character string by the character input device of the present invention will be described. In addition, during the explanation, the numbers of the processing steps in FIG. 2 are quoted in parentheses.

When the input string is a mixture of kana strings and alphanumeric strings, "5qrL(2)", convert this to 1.1.
Let us take as an example the case where the characters are converted to "4142136".

When the character string "5qrL(2) ni Kankansuru" is input, "5qrt(2) ni Kankansuru" is stored in the character input cover sofa (Fig. 2, 20), and when the [Convert] key is pressed, the character Jjt is identified. (Fig. 2 21.25.2)
6), where alphanumeric characters 5qrt(2) `` or a character string ``
``Nihenkansuru'' is identified.

The selected kana character strings are converted into consecutive phrases through dictionary access processing to find candidates (Figure 2, 28).
The alphanumeric string "5qrt (2) saves the string as it is as a candidate (Figure 2, 32), while character analysis determines that it is a function calculation and selects the corresponding "5qr
LJ (square root)) operation is executed, and the result is “1.1
4142136° is calculated (Fig. 2, 33). In this way, the candidates extracted by the kana-kanji conversion, the results obtained by the calculation process, and the alphanumeric character string are output as candidates, and a candidate group is created. 2 Figure 29).

From the candidate group obtained in this way, the answer is "convert to 5qrL(2)" as the first conversion result.
1.Display 14142136°. When the user sees this display and presses the [Convert] key for the second time, the next candidate "1.1414213" that has already been created by the candidate group creation process is displayed.
1.141 with “6” replaced with “5qrL (2)”
42136 is displayed (Fig. 2, 31).
).

When the user looks at this display and presses the [ENTER] key, the currently displayed content is determined as the input character string from among the candidates, and processing such as storage is performed (FIG. 2, 24).

Since this is not necessary, it is possible to simplify the operation.
