Abstract

PURPOSE: To improve conversion efficiency by displaying input characters, which are surely to be represented in KATAKANA(square form of Japanese syllabary),as KATAKANA characters. CONSTITUTION: When HIRAGANA(cursive form of Japanese syllabary) characters 'TOUKYOU' are inputted, the HIRAGANA character string 'TOUKYOU' is reversed and displayed at the lower stage on a display 4. When a sonant mark key is operated successively to the input of 'U', a KATAKANA character 'VU' corresponding to the character 'sonant of U' obtained by adding a sonant mark to the character 'U' is read out of a KATAKANA conversion information table and stored in an undetermined character memory, and a converted character string 'TOUKYOVU' in an undetermined state is displayed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing device,
In particular, it relates to something that improves katakana character input and kanji conversion expressed in katakana such as "v", "va", and "vyo" in hiragana input mode and romaji hiragana input mode.

[0002]

2. Description of the Related Art Conventionally, in a document processing device such as a Japanese word processor, a keyboard provided with a large number of character keys and function keys and a display capable of displaying text data input from the keyboard are basically used. It is possible to input desired text data by sequentially inputting various printable keys such as character keys, number keys and symbol keys on the keyboard, and it is possible to display the input text data on the display. Has become.

In this type of document processing apparatus, normally,
Enter the entered characters as "Hiragana characters" or "Katakana characters"
When the Hiragana input mode is set by operating the Hiragana mode key so that it can be converted to or "Kanji" arbitrarily, the characters input by operating the Hiragana character keys can be displayed in "Hiragana characters" or the Roman character mode key operation When you set the Romaji Hiragana input mode, the Romaji entered by operating the alphabetic character keys will be converted to Hiragana, and then “Hiragana characters” will be displayed in the same way.
Can be displayed, and thereafter, the kanji conversion key is appropriately operated to convert it into a desired kanji character, or the katakana conversion key is operated to be provided with an input character conversion function for converting into a katakana character, which enables document processing.

By the way, at present, a wide variety of word processors are put into practical use, and depending on the model, in the hiragana input mode, special characters that can be expressed only by Katakana characters, for example, "V", are operated characters. By operating the "u" key and the dakuten key, the character is displayed as "u no dakuten", and the katakana conversion key is operated to convert the katakana character to "v". On the other hand, in the Roman character hiragana mode, for example, the Roman character “VAIORIN
When inputting "N" to display the katakana character "violin", when inputting the Roman character "VA", there is a case where the Roman character "VA" is displayed as it is without being converted into hiragana.

Further, when the roman character "TOUKYOUVIORINN" is input to display "Tokyo violin", the character string "Tokyo (Uno dakuten) Ai-orin" is displayed. Move to Hiragana “Tokyo”, convert the hiragana “Tokyo” to the kanji “Tokyo”, and then move the cursor to the letter “n” to read the hiragana “(Uno dakuten) airin”.
Is converted to katakana character "violin".

[0006]

As described above, in the document processing apparatus having the input character conversion function, normally,
Even when the characters "V" and "V" that are always expressed in katakana are input as text and displayed on the display, they are displayed as "Hiragana characters" with the "Voice mark" added to the character "U". There is a problem in that the katakana conversion operation may be forgotten for a character string containing this character "Unodaku". In addition, since the characters "VA" entered in Roman letters are not converted to "Hiragana characters", the input mode is switched to Katakana input mode and the Katakana character "V" is entered.
To enter the letters "va", "vi",
There is a problem that the input operation of katakana characters expressed in katakana such as “V”, “V”, etc. is troublesome and the operability is poor.

Further, when displaying the text "Tokyo violin" in which kanji and katakana characters are mixed, the cursor is moved to the conversion target character string for kanji conversion or katakana conversion for a series of input character strings that have been input. Therefore, there is a problem that the conversion operation becomes complicated.

An object of the present invention is to display an input character that is always expressed in katakana in katakana characters, and improve the conversion efficiency of converting to katakana or katakana through the katakana characters. To provide.

[0009]

According to a first aspect of the present invention, there is provided a document processing apparatus, wherein input means for inputting various data and commands and input modes of the input means are at least hiragana input mode and romaji hiragana input mode. In the document processing apparatus including the input mode setting means for selectively setting the input character data, the data storage means for storing the input character or symbol data, and the display means having the display, the hiragana of one syllable is supported. Among one or a plurality of conversion target characters, a conversion target character always expressed in katakana and a plurality of sets of katakana conversion information storage means in which the katakana characters are associated and stored, and one or a plurality of syllables from the input means. Of the input character data, the converted character string search means for searching the katakana conversion information storage means, and the corresponding input character by the converted character string search means When it is issued, the Katakana character corresponding to the input character is read and displayed on the display means, and when the corresponding input character is not detected, the conversion control means for displaying the input character in hiragana on the display means is provided. It is a thing.

Here, the katakana conversion information storage means includes a conversion target character including the characters "u" and "voiced point",
You may comprise so that the conversion information corresponding to the character "V" may be included (Claim 2 dependent on Claim 1). Further, when converting a kanji dictionary storing a plurality of kanji corresponding to one or a plurality of hiragana characters and a character string to be converted, in which hiragana characters are mixed with katakana characters, received from the conversion control means, kana characters are converted. A kanji character conversion control means for performing kanji character conversion on a character string delimited by a character and a character immediately preceding it may be provided (claim 3 dependent on claim 1 or claim 2).

[0011]

In the document processing apparatus according to the present invention, the katakana conversion information storage means includes a conversion target character which is always expressed in katakana among one or a plurality of conversion target characters corresponding to the hiragana of one syllable. Since a plurality of sets are stored in association with the katakana characters, the conversion character string search means receives one or more input character data for each syllable from the input means in the hiragana input mode or the romaji hiragana input mode. Search the katakana conversion information storage means. Then, the conversion control means, when the corresponding input character is detected by the converted character string searching means, reads the katakana character corresponding to the input character and displays it on the display means, and when the corresponding input character is not detected, The input character is displayed in hiragana on the display means. As a result, the display of the display means displays a character string in which hiragana characters and katakana characters are mixed.

As described above, when a character is input in the hiragana input mode or the romaji hiragana input mode, katakana conversion information in which the conversion target character and the katakana character are associated with each other for one or more input characters for each syllable is retrieved. When the input characters are not always expressed in katakana, the input characters are displayed in hiragana and the input characters that are always expressed in katakana are displayed in that katakana character. You can input in the Roman alphabet and Hiragana input mode without switching to input mode, and you can easily recognize that the character string containing this Katakana character is Katakana by looking at the displayed Katakana characters and forget the Katakana conversion operation. There is no.

In addition to the flag data memory 57, C
A memory, a buffer, etc. for temporarily storing the calculation result calculated by the PU 40 are provided.

Next, the routine of the document processing control performed by the control device CD of the tape-shaped label producing apparatus 1 will be described with reference to the schematic flowcharts of FIGS. In the figure, reference numeral Si (i = 10, 11, 12, ...
・) Is each step. When the power is turned on by operating the power key on the keyboard 3, the thermal printing mechanism PM
After various initialization processes such as initializing are executed, this control is activated, a text input screen in which text input is possible is displayed on the display 4, and an input mode flag MF and a kana display flag KF are displayed. Set respectively (S
Ten). As a result, the hiragana input mode is set and the input characters are displayed in hiragana.

When the Roman character mode key is operated (S11 / S12: Yes), the input mode flag MF is set, and when the hiragana input mode is selected (S).
19: Yes), the input mode flag MF is reset, and the Roman character hiragana input mode is set (S20),
Return to S11. Further, when the hiragana mode key is operated (S11: Yes, S12: No, S13: Yes), the input mode flag MF is reset, and when in the Roman character hiragana input mode (S21: Yes), this input mode is selected. The flag MF is set, the hiragana input mode is set (S22), and the process returns to S11.

When a hiragana character key or alphabetic character key is operated (S11: Yes, S12.
(S13: No, S14: Yes), undetermined character registration processing control (see FIG. 7) is executed (S23). This control is started,
When the hiragana input mode is set (S40:
Yes), when the operated key is a hiragana character key (S45: No), the hiragana character code data corresponding to the character key is stored in the input buffer 52 (S4).
8).

When the number of undetermined hiragana characters registered in the undetermined character memory 53 is 14 or less and the character can be registered in the undetermined character memory 53 (S4
9: Yes), the input character stored in the input buffer 52 is subjected to a search process for searching the data of the katakana conversion information table TB1 (S50), and when the corresponding input character is detected (S51: Yes). The katakana character read from the katakana conversion information table TB1 is registered in the undetermined character memory 53 (S52). Furthermore,
The conversion target character registered in the undetermined character memory 53 is displayed on the display 4 by reversing (S53), the input buffer 52 is cleared (S54), this control is ended, and the process returns to S11 of the document processing control. .

However, the katakana conversion information table TB1
When the corresponding input character is not detected as a result of searching the data of (S51: No), the hiragana character corresponding to the input character key is registered in the unconfirmed character memory 53 (S55) and highlighted in S53. , S54 to end this control and return to S11. If it is impossible to register in the undetermined character memory 53 (S49: No),
An error message to that effect is displayed on the display 4 (S56), and similarly, the process returns to S11.

By the way, when this control is started,
When the operated key is the dakuten key (S45: Yes),
Dakuten processing control is executed (S46). That is, the final hiragana character stored in the undetermined character memory 53 is read, and the hiragana character is, for example, each character such as ka line, sa line, ta line ... Sometimes, it is converted into one-character code data in which a hiragana character is added to the hiragana character and stored in the input buffer 52. However, when the hiragana characters are, for example, each character such as A line, Nana line, etc., and it is impossible to add the dakuten, the error flag is set. If the error flag is not set (S47: No), S49 and the subsequent steps are executed, but when the error flag is set (S47: No).
Yes), and returns to S11.

For example, when the hiragana character string "Tokyo" is input while the hiragana input mode is set, the hiragana character string "Tokyo" is displayed in the lower part of the display 4, as shown in FIG. 10 (a). Is displayed in reverse video. Next, when the character “U” is input, the character “U” is additionally displayed and highlighted as shown in FIG. 10B. Further, when the dakuten key is operated, the katakana character "v" corresponding to the character "u no dakuten", which is the final hiragana character "u" added with the dakuten, is read from the katakana conversion information table TB1, 10 as well as being stored in the undetermined character memory 53.
As shown in (c), the conversion target character string "Tokyo" is displayed in an undetermined state.

Next, in the document processing control, when the Kanji conversion key is operated (S11: Yes, S12 to S14: N).
o, S15: Yes), and kanji conversion processing control (see FIG. 8) is executed (S24). When this control is started, first, the conversion target character string stored in the undetermined character memory 53 is searched for katakana characters read from the katakana conversion information table TB1 (S60). Next, when the katakana character is detected (S61: Yes), the kanji conversion processing based on the data of the kanji dictionary is performed on the conversion candidate character string delimited by the katakana character and the character immediately before it. This is executed (S62), the Chinese character is displayed in reverse on the display 4 instead of the conversion candidate character string (S64), the control is terminated, and the process returns to S11.

For example, as shown in FIG. 11 (a), when the hiragana character string "Tokyo Vai Orin" is displayed on the display 4 in reverse video, the Kanji conversion key is operated. Occasionally, the conversion candidate character string "Tokyo" that separates the katakana character "V" and the character "U" immediately preceding it is converted to the Chinese character "Tokyo", and as shown in FIG. The kanji “Tokyo” is highlighted instead of the candidate character string “Tokyo”.

However, as a result of searching for the character string to be converted, if the katakana character is not detected (S6
1: No), Kanji conversion processing based on the data of the Kanji dictionary is executed with all the conversion target character strings stored in the undetermined character memory 53 as conversion candidate character strings (S63), S
After 64, the control is terminated and the process returns to S11.
At this time, the undetermined character memory 53 stores the kanji code data instead of the conversion candidate character string.

In the document processing control, for example,
When the non-conversion key is operated (S11: Yes, S12-
(S18: No), in the undetermined character memory 53, a process of converting the Chinese character into the original Hiragana or Katakana character string before conversion and storing it is executed (S30), and the process returns to S11. on the other hand,
When the hiragana / katakana conversion key is operated (S
11: Yes, S12 to S15: No, S16: Yes), Hiragana /
Katakana conversion processing control (see FIG. 9) is executed (S2
Five).

When the display flag KF is set when the control is started and the character strings to be converted are displayed in Hiragana (S70: Yes), all the character strings to be converted in Hiragana are displayed. Converted to katakana characters and displayed on display 4 (S71), display flag KF
Is reset and switched to katakana display (S7
2) Then, this control is terminated and the process returns to S11.
However, when the display flag KF is not set and the conversion target character string is displayed in katakana (S70:
No), all the katakana conversion target character strings in this conversion target character string other than the katakana characters read from the katakana conversion information table TB1 are converted into hiragana characters and displayed on the display 4 (S73), and displayed. The flag KF is set to switch to hiragana display (S74), the control is terminated, and the process returns to S11.

For example, as shown in FIG. 11B, when the conversion target character string "Tokyo Vai Orin" is highlighted, when the hiragana / katakana conversion key is operated, the hiragana conversion is performed. All the target character strings "AIORIN" are converted into katakana character strings "Violin",
As shown in (c), the conversion target character string “Tokyo violin”, which is an undetermined character string, is highlighted.

In the document processing control, when the line feed key is operated (S11: Yes, S12 to S16: No,
S17: Yes), the data of the conversion target character string stored in the unconfirmed character memory 53 is stored in the text memory 51 as a confirmed character string (S26), and the unconfirmed character memory 53 is cleared (S27), Furthermore, this text memory 5
The text data stored in 1 is displayed on the display 4 in the normal display after the reverse display is stopped (S2
8) Return to S11. For example, as shown in FIG. 11C, when the conversion target character string “Tokyo violin”, which is an unconfirmed character string, is highlighted and the line feed key is operated, it is illustrated in FIG. 11D. As described above, the text "Tokyo violin" confirmed as the text data is normally displayed on the display 4.

By the way, when the alphabetic character key is operated to start the undetermined character registration processing control and the Roman character hiragana input mode is set (S40: No), the input alphabetic character is When the conversion target character is not established, for example, when a consonant character is input alone without the alphabetic vowel characters "A, I, U, E, O" (S41: N).
o), the input character which is the consonant character is stored in the Roman character buffer 51 and displayed on the display 4 (S4
4) Then, this control is ended, and the process returns to S11.

When a vowel character is input by operating the alphabetic character keys and the undetermined character registration processing control is executed again, when the vowel character is stored in the Roman character buffer 51 and is established as a conversion target character. (S41: Yes), a Hiragana conversion process is executed to convert the input characters of Roman characters, which are obtained by adding vowel characters to one or more consonant characters, stored in the Roman character buffer 51 into Hiragana (S42), and the Roman character buffer 51. Is cleared (S43), and the input character of the hiragana is stored in the input buffer 52 (S48). Then, after S48 is executed as described above, when a katakana character corresponding to the input character is detected, the katakana character is displayed on the display 4, or when the corresponding katakana character is not detected, the input character is hiragana. Is displayed.

For example, when the Roman character "TO" corresponding to the hiragana of one syllable is input, the Roman character "T" is displayed on the upper stage of the display 4, as shown in FIG.
"O" is displayed for a very short time, and then, as shown in FIG. 12B, the hiragana "to" corresponding to the Roman character "TO" is highlighted on the display 4. Then, as shown in FIG. 12C, when the undecided hiragana character string "Tokyo" is highlighted on the display 4, when the Roman character "VA" is input, the Roman character "VA" is changed. After being displayed (see FIG. 12C), the Roman character "VA" is displayed as shown in FIG.
Is converted into a one-syllable hiragana “(u no dakuten) a”, and the katakana character “va” corresponding to the hiragana “(u no dakuten) a” is highlighted in the lower part of the display 4.

Then, as shown in FIG. 13 (a), when the undetermined hiragana character string "Tokyo Vai Orin" is highlighted on the display 4, the conversion candidate is operated by operating the Kanji conversion key. When the character string "Tokyo" is converted into Kanji as described above,
As shown in (b), the unconfirmed conversion target character string “Tokyo Va Iori” is highlighted. In addition, hiragana /
When the katakana conversion key is operated by operating the katakana conversion key, as shown in FIG. 13C, the conversion target character string “Tokyo violin”, which is an undetermined character string, is highlighted. Then, as shown in FIG. 13D, the text "Tokyo violin" confirmed as text data is normally displayed on the display 4 by operating the line feed key.

Next, the operation of the document processing control for displaying the katakana character when it is always expressed in katakana among the conversion target characters corresponding to the hiragana of one syllable will be described. First, in the Roman character input mode, the input Roman characters are converted into Hiragana for each syllable and input. When a character is input in the Roman character input mode or the hiragana input mode, the katakana conversion information table TB1 in which the conversion target character and the katakana character are associated with one or more input characters for each syllable
When is not searched for and is not necessarily expressed in katakana, the input characters are displayed in hiragana and, for input characters that are always expressed in katakana, the katakana character is displayed. , It is possible to input in Romaji-Hiragana input mode without switching to Katakana input mode, and also by observing the displayed Katakana characters, it is possible to easily recognize that the Hiragana character string containing this Katakana character is Katakana conversion. Never forget the operation.

Further, the katakana conversion information table TB
Since 1 includes conversion information in which the conversion target character including the characters "u" and "voiced point" and the character "v" are associated,
Basic katakana character "V" that is always expressed in katakana
"Va", "Vii", "Ve", "Vu" using ...
, Etc. are displayed by using the katakana character “V”, it is possible to reliably recognize the necessity of the Katakana conversion operation for the character string including the Katakana character “V”.

Further, as a conversion target character string in which hiragana characters are mixed with katakana characters, for example, when converting the conversion target character strings "Tokyo Vai Orin" and "Tokyo Vai Orin" into kanji, Converts the katakana character "V" or "Va" and the preceding character "U" as a delimiter to the Kanji character string, so the conversion target character string for Kanji character conversion is Since it is not necessary to move the cursor K to give an instruction, it is possible to improve conversion efficiency when converting Kanji.

It should be noted that the unconfirmed conversion target character string is underlined and displayed, or a large-sized display is provided. Various modifications may be made based on the above technology. It is needless to say that the present invention can be applied to various document processing apparatuses equipped with a keyboard and various displays.
