Abstract

PURPOSE:To input efficiently a mixed character string where a KATAKANA (square form of Japanese syllabary) character string follows a HIRAGANA (cursive form of Japanese syllabary) character string, by inputting the character string with KATAKANA characters and changing KATAKANA characters to HIRAGANA characters if the end of the character string is a specific KATAKANA character. CONSTITUTION:Contents of a mode register 4 are changed to the KATAKANA input mode by a mode changing means 3. When a character string is inputted from a character input means 2, the inputted character string is converted to character codes by a character set means 6 in accordance with contents of the mode register 4 and they are set to a character string buffer 5. When the end of input is reported by a delimiting information input means 7, a character string substituting means 9 compares the end of the character string in the character string buffer 5 with contents of a substitution character string memory 8 where 'o', 'kara', 'he', 'ni', 'to', 'ga', etc. are stored; and if a part coincides with contents, this coinciding part is substituted with HIRAGANA writing.

Description

[Detailed Description of the Invention] [Field of Application in Industry-1-] The present invention relates to a character string input device for inputting katakana characters in katakana input mode, and more specifically, a katakana character string followed by a kana character string. The present invention relates to a character string input device that can efficiently input mixed character strings.

[Prior art and its problems]

In recent years, with the spread of Japanese document creation devices such as word processors, there has been a widespread demand for efficient Japanese input methods.

Katakana input on Japanese document creation devices is usually done using
A commonly used method is to enter a character string after switching to katakana character input mode. For example, when inputting the katakana character string "system", the user first enters the katakana character string input mode by pressing the katakana mode transition key, and then enters the kana character string "shisutemu". Finally, the character string ``system'' is obtained by pressing a key (such as a non-conversion key) without confirming that the input is completed. Although this conventional device has the advantage that it is not necessary to register complicated words written in katakana in the dictionary, it treats the entire bifurcated character string as katakana, so for example, 1 sysdem is -1 Hiragana character strings (often placed at the end of katakana as adjuncts when inputting phrases,
When inputting a character string followed by maj = there aren't many types of them), you usually first enter katakana mode.

You have to step on the button, and the input efficiency is extremely poor.

[Object of the Invention, 1] An object of the present invention is to provide a second character string input device that can input a mixed character string in which a katakana character string is followed by a kana character string with high efficiency.

[Inventiveness composition]

According to the present invention, there is provided a character input means for manually inputting kana characters, a mode changing means for changing a mode indicating whether the kana characters are hiragana or katakana, a character string buffer, and a character string buffer for inputting the kana characters. a character setting means for inputting hiragana or katakana into the character string buffer according to the mote; a delimiter information input means for inputting information indicating a delimiter of input; In a character string input device equipped with a character string output means for passing contents to an external information processing device, when the end of the contents of the character string buffer is a separately determined specific katakana, the specific katakana is changed to hiragana. A character string input device characterized by being equipped with a character string replacement means can be obtained.

〔Example〕

1? J. Below, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in the description within this specification, a single character is also included in the "E character string".

FIG. 1 shows a first embodiment of the invention. In the figure,
1 is a control unit that performs overall control and receives input data from various information input means to be described later; 2 is a character input means for inputting ephemeral characters; and 3 indicates that the current input is Hiragana. 4 is a mode register for storing the mode information; 5 is a character string buffer for storing the input character string; , 6 is a character setting means for setting the kana characters sent from the character input means 2 into the character string buffer 5 as hiragana or katakana according to the contents of the mode register 4, and 7 is for inputting information indicating the delimitation of input. 8 is a delimiter information input means for storing character strings to be replaced.
9 is a replacement string memory, 9 is a string replacement means that refers to the replacement string table 8 based on the contents of the string buffer 5, and replaces a string as necessary; 10 is a string replacement means for replacing a string as necessary; This is a character string output means for passing the contents of the buffer 5 to the information processing device.

FIG. 3 shows an outline of the character input procedure according to the first embodiment. Here, the operation of the first embodiment will be explained by taking as an example the case where the system inputs ''.

-Ra- First, since the first character to be input is katakana, when the user inputs a mode change instruction using the mode change means 3, the control unit 1 receives this information and changes the contents of the mode register 4 (mode information ) to katakana input mode (the initial state is hiragana input mode). Next, the user inputs the first character "" from the character input means 2.

When the character "L" is input, the character "L" is sent to the character setting means 6. Under the control of the control unit I, the character setting means 6 knows whether the input character is Hiragana or Katakana based on the state of the mode register 4, and converts the character code (for example, from a 1-byte code to a 1-byte code) if necessary. (to 2-byte code)
After doing this, transfer the obtained character code to string buffer 5
Set to .

In this example, since the mode register 4 indicates the katakana input mode, the katakana character code ``'' is set in the character string buffer. When te°, ゛′um″, ``を′” are input, the character string buffer 5 is filled with ``space'', ``''
``Te''', ``Mu'', and ``゛°'' are set, and as a result, ``°System'' is set in the character string buffer 5.

When the user informs the control unit 1 that inputting the delimiter information manually to the delimiter information means 7 is completed, the control unit 1 starts the character string replacement means 9. Character string replacement means, control unit 1
Under the control of (If not, nothing will be done). The replacement character string memory 8 stores “wo”, “kara”, ゛he, -he, “do”, “ga”, etc. In this example, the contents of the character buffer 5 “ Since the last character of ``system wo'' exists in the replacement string memory 8, the string replacement means 9 replaces pa with pa. As a result, the contents of the character string buffer 5 become "°' for the system."

Thereafter, the contents of the character string buffer 5 are sent to the character string output means 10 under the control of the control section 1, and finally "Sisteno, wo" is output.

In the first embodiment, the character set means 6 can be easily realized by simple code conversion, and the character string replacement means 9 can also be realized by table search and character string replacement.

FIG. 2 shows a second embodiment of the invention. In this embodiment, a replacement instruction input means 11 for instructing the activation of the character string replacement means 9 is added to the constituent elements indicated by reference numerals 1 to 10 in FIG.
is added.

FIG. 4 shows an outline of the character input procedure according to the second embodiment. Here, the operation of the second embodiment will be explained, taking as an example the case where the above-mentioned "system" is input.

The steps from the first mode change by the user to the character input method using the character input means 2 are the same as those described in the first embodiment. At this point, "'system ヲ゛'" is set in the character string buffer 5.Here, when the user instructs to perform a replacement using the replacement instruction input means 11, the control unit 1 that receives this information The means 8 is activated to perform a process of replacing the character string in the character string buffer 5.The process of replacing the character string itself is the same as that described in the first embodiment.As a result, the desired character column”
After obtaining the system value, it can be outputted by the character string output means 10.

Next, we will explain the case of inputting the character string ``Aksen Ipa''.The user sets the ``system'' to the katakana input mode using the mode change means 3, as in the case of ``'', and then From 2, enter “a′, ゛<, “se′, ゛n′,” and ′°.

At this point, "accent" is set in the character string buffer 5. When the user uses the delimiter information input means 7 to inform the control unit 1 that the input has been completed, the contents of the character string buffer 5 are sent to the character string output means 10 under the control of the control unit 1.゛It is possible to output an accent pad.

In this way, when the second embodiment is used, the replacement instruction input means 11 is used when the last katakana character string is to be replaced, and the delimiter information input means 7 is used when the last katakana character string is not to be replaced. It is possible to choose the form.

〔Effect of the invention〕

1'J, as mentioned above, by using the present invention,
It is possible to input katakana character strings together with kana character strings, which are relatively frequently used, while suppressing troublesome mode changes.
