Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a character processing device for inputting a kanji / kana mixed sentence by kana / kanji conversion. In particular, the present invention relates to a device for inputting a number and converting it into a symbol that represents a number such as a Roman numeral (for example, IV) or a circled numeral (for example).

[Prior Art] When creating a Japanese sentence, there are often opportunities to use "symbols representing numbers" such as Roman numerals and circled figures as titles and headings. Since current Japanese word processors and the like generally use Kana-Kanji conversion to input characters, such symbols are input by inputting numbers and converting them into Kana-Kanji.

As for symbols that express such numerical values, the same type tends to be continuously used. For this reason, the apparatus is configured such that once a certain number conversion candidate is selected, the next time the number is converted, the same type of candidate as the number conversion candidate selected immediately before is converted as the first candidate. It is common. That is, it is a learning function for digit conversion.

[Problems to be Solved by the Invention] However, according to such a learning function for digit conversion, it is possible to input symbols relatively comfortably in the document creation stage, but not to input as desired in the proofreading stage.

For example, when it is desired to change the numerical value to or V in a sentence in which or IV has already been input, or the cursor is placed on IV and the numeral "5" is typed to convert it. Since the conversion result of the number conversion is determined by the learning function, if the number conversion candidate selected immediately before that is (8), (5) will be converted regardless of the character on the cursor. In order to convert V as intended, the next candidate must be displayed with the next candidate key.

[Means (and Action) for Solving the Problems] In order to solve the above problems, the character processing device of the present invention is
Input means for inputting a number, cursor display means for displaying a cursor for indicating a display position of the number input by the input means, and type of character existing at the position of the cursor displayed by the cursor display means Discriminating means, converting means for converting the number inputted by the input means into a plurality of types of numerical expressions representing the numeral, candidate displaying means for displaying the conversion result by the converting means, and displaying by the candidate displaying means. Selecting means for selecting one numerical expression from a plurality of types of numerical expressions, display control means for displaying the numerical expression selected by the selecting means at the position of the cursor, and numerical expression selected by the selecting means. And a storage unit that stores the type of the character, and the candidate display unit displays the conversion result of the conversion unit. When the type is one of the numerical expressions, the numerical expression of the type discriminated by the discriminating means is preferentially displayed, and when the type of the discriminated character is not the numerical representation, it is stored in the storage means. It is characterized by preferentially displaying the numerical expressions of the selected types.

Further, in the character processing method of the present invention, in a character processing device having an input unit for inputting information, a display unit for displaying information, and a storage unit for storing the type of numeral expression, a cursor is placed on the display unit.

FIG. 2 is a diagram showing a conversion example of digit conversion in the present invention.

2-1 is a screen in a state where nothing is input. The cursor is underlined. If the number "2" is input in this state, a screen 2-2 is displayed.

In 2-2, the number "2" is displayed as a reading. Here, when the conversion key is pressed, the number "2" is converted and a 2-3 screen is displayed.

The screen of 2-3 is a state in which the number "2" is converted. Here, “II” has been converted as the first candidate because “VI” or the like has been selected immediately before. When the next candidate key is pressed in this state, a screen 2-4 is displayed.

In 2-4, the next candidate for digit conversion is displayed, and a list of candidates is displayed. Since "" which is the intended candidate is displayed here, when it is selected, the screen of 2-5 is displayed and "" is selected and confirmed.

FIG. 3 is a diagram showing a conversion example in the case where the conversion result of digit conversion exists on the cursor.

3-1 is a screen showing a state in which "" has already been input on the cursor. When the number "2" is pressed in this state, a screen 3-2 is displayed.

The screen 3-2 is a screen in which the number "2" is displayed as a reading, and when the conversion key is pressed here, the screen 3-3 is displayed.

In 3-3, the number "2" is converted into "". That is, since "" originally existed on the cursor, "" was determined as the first candidate among other candidates for digit conversion due to the influence.

FIG. 4 is a diagram showing a character code table of symbols for digit conversion in the present invention. The JIS X 0208 code is used as the character code of the basic character, and the code of the symbol for digit conversion is assigned to the area not used by the JIS X 0208 code.

FIG. 5 is a diagram showing the configuration of a numeral conversion table based on the character code table shown in FIG.

The left field indicates the start code and the right field indicates the end code. For example, with respect to the type 1 symbol, 7421 to 7A2A are assigned, and it is understood that 7421 is a symbol having a value of "1".

FFFF is stored at the end so that the end of the table can be identified.

FIG. 6 shows an input buffer IBUF and an output buffer OBUF.
It is a figure showing the composition of.

Both IBUF and OBUF have the same configuration. The first 2 bytes are the size information of each buffer, and the numerical value obtained by doubling the value obtained by subtracting 1 from the number of characters stored in the buffer is entered. The "" at the end of the input buffer means that the conversion key was pressed there. Each character consists of 2 bytes per character and is stored in JIS X 0208 code.

FIG. 7 is a diagram showing the structure of the text buffer TBUF.

The text is composed of a plurality of fixed length character data. Each character data consists of 2 bytes per character.
Stored as SX 0208 code.

The MSB is a flag indicating whether the character is a fixed normal character or a homophone capable of displaying the next candidate. A value of 0 means a normal character, and a value of 1 means a homophone code. In the case of a homophone code, a homophone number is stored instead of the JIS X 0208 code of the character code. By referring to the homophone word buffer shown in FIG. 11 based on the homophone word number, it is possible to know what kind of candidate the homophone word is, or the nature of the homophone word.

FIG. 8 is a diagram showing the structure of the homophone word buffer DOBUF.

“Yomi” stores the reading string of the homophone. For example,
The same phoneme “answer” is stored as “kaito”.

The “total number of candidates” stores the total number of conversion candidates stored in the homophone word buffer. For example, the conversion candidates for the homonym “answer” are “answer”, “answer”, “phantom thief”, and “presiding”
If so, the value 4 is stored.

The “candidate number” stores a value indicating the number of candidates from the beginning of the currently designated candidate (that is, the currently displayed candidate) of the homonym. In the state immediately after conversion, the value 1 is stored and the first candidate is displayed. Each time the next candidate key is pressed, 1 is added to this value and the next candidate is displayed.

The "display" stores the notation of each conversion candidate.

The “conversion type” stores the type of numeral conversion when the conversion candidate is a candidate for numeral conversion. For example, the value 1 is stored for type 1 and the value 2 is stored for type 2. When it is not a candidate for digit conversion, an invalid value 0 is stored.

FIG. 9 is a diagram showing the structure of the current conversion type CCONTP.

The current conversion type is a work that stores the conversion type of the numerical conversion candidate selected immediately before, and the work of learning the numerical conversion is performed.

The current conversion type consists of 1 byte. For example, the value 1 is stored when the last selected digit conversion is type 1, and the value 2 is stored when it is type 2.

The value 0 is stored when learning is not performed.

The operation of the above embodiment will be described according to the flow.

FIG. 10 is a flow chart of a part for receiving a key input and performing a process.

Step 10-1 is a process for fetching data from the keyboard. The type of the key fetched in step 10-2 is determined, and the process branches to each key processing routine.

If it is a conversion key, the process branches to step 10-3, and in step 10-3, conversion process of kana-kanji conversion is performed as described in detail in FIG.

If it is the next candidate key, the process branches to step 10-4,
Next candidate processing is performed as described in detail in FIG.

If it is the select key, the process branches to step 10-5 and the selecting process is performed as described in detail in FIG.

If the key is any other key, the process branches to step 10-6, and other processes such as insertion and deletion that are carried out in a normal character processing device are carried out.

After that, the process branches to step 10-1.

FIG. 11 is a detailed flowchart of the "conversion process" in step 10-3.

In step 11-1, it is determined whether the input reading is a number. If it is a numeral, it branches to step 11-2 to perform numeral conversion processing, but if it is not a numeral, step 11
The process branches to -7, the ordinary kana-kanji conversion processing is performed, and the process branches to step 11-8.

In step 11-2, the numeric conversion table CONTB
According to L, the input character code is converted into numbers. At this stage, a plurality of conversion candidates are stored in the buffer.

In step 11-3, the character on the cursor is read from the text buffer TBUF.

In step 11-4, it is determined whether or not the character on the cursor read in step 11-4 is a code of a symbol (numerical conversion code) converted by numerical conversion by referring to the numerical conversion table CONTBL. If it is a numeral conversion code, the conversion type is also obtained at the same time, and the process branches to step 11-5, and the candidate of the conversion type is determined as the first candidate.
If it is not a numeric conversion code, the process branches to step 11-6 and the conversion candidate of the current conversion type CCONTP is determined as the first candidate. After that, the process branches to step 11-8.

A homophone word buffer is created in accordance with the first candidate determined in step 11-8.

In step 11-9, the conversion result is created in the output buffer OBUF based on the homophone word buffer and is output.

FIG. 12 is a detailed flowchart of the "next candidate process" in step 10-4.

In step 12-1, the corresponding homophone word buffer is obtained from the character data at the cursor position.

In step 12-2, the current candidate number of the homophone word buffer obtained above is counted up and set as the next candidate.

In step 12-3, the candidate list is displayed.

FIG. 13 is a detailed flowchart of the "selection process" in step 10-5.

In step 13-1, the corresponding homophone word buffer is obtained from the character data at the cursor position.

In step 13-2, the process of determining the candidate indicated by the current candidate number of the homophone word buffer obtained in the text buffer TBUF is performed. As a result, the character data is not a homophone and becomes a normal character.

In step 13-3, if the candidate list is displayed, it is deleted.

In step 13-4, the conversion type of the confirmed homophone word candidate is extracted, and if it is a candidate for numeral conversion, the conversion type is substituted for the current conversion type. As a result, learning will be performed the next time the numbers are converted.

[Other Embodiments] In the above description, the character to be converted in the number conversion has been described as a single character, but the same processing can be performed when converting a number into a plurality of character strings. For example, this corresponds to the case of converting a numeric string into Chinese numerals.

In this case, too, the same process can be performed by reading the character on the cursor and changing the first candidate accordingly.

However, at this time, it becomes more convenient if it is necessary to accurately remove the existing Chinese numeral string and replace it with the newly converted result.

[Effect of the Invention] As is apparent from the above description, according to the present invention, when converting a number, if the character on the cursor is the conversion result of the number conversion, the conversion candidate of the conversion type is the first candidate. Otherwise, since the conversion candidate of the same conversion type as the conversion candidate of the previously selected numerical conversion is set as the first candidate, the numerical conversion is performed in accordance with the intention of the operator, so that the operability is high. A character processing device can be realized.
