JP3843010B2 - Kana-kanji conversion device - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a Kana-Kanji conversion device, and more particularly to a Kana-Kanji conversion device having a relatively small display screen, such as a mobile communication terminal such as a mobile phone or a PHS terminal, or a portable information device.
[0002]
[Prior art]
In recent years, mobile communication terminals such as mobile phones and PHS terminals have become more sophisticated, and have a function capable of sending and receiving text mail. Using a kana-kanji conversion function, it is easy to read messages containing kanji. Opportunities to use the Kana-Kanji conversion function in mobile terminal devices, such as creating, are increasing.
[0003]
When performing kana-kanji conversion operations, it is easier to input kanji by converting with multiple phrases. Therefore, in the kana-kanji conversion device capable of multi-phrase conversion, the input reading is temporarily stored in the buffer, and when the conversion key is pressed, conversion candidates such as kanji and katakana corresponding to the reading are stored. The input reading is divided into phrases at the breaks where conversion candidates exist in the dictionary. Next, each conversion candidate of the compound phrase is combined and converted into kanji or kanji kana mixed sentences, and each time the conversion key is pressed for the result of the batch conversion, the combination of conversion candidates for each phrase is mixed with kanji kana Convert to sentence. Then, the first phrase conversion candidate matches the desired conversion candidate. For example, the second phrase conversion candidate can be selected only when the confirmation key is pressed. Select conversion candidates from the first phrase to the second and third phrases in such a way that the third phrase conversion candidates can be selected only when the confirmation key is pressed in line with the desired conversion candidate. I will do it.
[0004]
Also, as a result of batch conversion, if all of the phrase conversion candidates match the desired conversion candidate, for example, all the keys stored in the buffer can be stored by pressing all the confirm keys without pressing the confirm key for each phrase. A function to confirm the character string has been added.
[0005]
Furthermore, in the Kana-Kanji conversion function described above, registering long character strings in the Kana-Kanji conversion dictionary with short character strings facilitates input by combining methods that allow long character strings to be input simply by inputting short character strings. There is something. For example, if you register the character string "Congratulations on your fans" in the dictionary as a conversion candidate corresponding to the character string "Fan", you can convert it to a long character string just by entering a short character string It becomes.
[0006]
[Problems to be solved by the invention]
However, in mobile communication terminals such as mobile phones and PHS terminals, the LCD display unit for displaying characters cannot be enlarged due to the need for miniaturization and weight reduction, so the number of characters that can be displayed by character input such as kana-kanji conversion is limited. It has been.
[0007]
Therefore, when inputting a long reading character string that exceeds the number of characters that can be displayed, the screen is sequentially scrolled while the input reading character string is stored in the buffer, and when the conversion key is pressed, the first phrase is displayed. Since the conversion contents are stored in the buffer, the subsequent phrase may not be displayed on the display section.
[0008]
Further, when a long character string is registered with a short character string, the reading character string before the conversion may fit on the screen but may not fit on the display unit after the conversion.
[0009]
At this time, when the user presses the all confirmation key while looking at the character string displayed on the display unit, all the clauses stored in the buffer are confirmed. There was a problem that even if it was not a candidate, it was decided.
[0010]
In view of the above-mentioned problems, the present invention determines only the displayed part and determines the part that is not displayed when the all confirmation key is pressed when the conversion content does not fit on the display part and is not displayed during conversion. An object of the present invention is to provide a kana-kanji conversion device that does not.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, in the kana-kanji conversion apparatus according to the present invention, a dictionary memory for storing a kana-kanji conversion dictionary in phrase units, an input means for inputting a reading character string, a display means for displaying characters, In a kana-kanji conversion apparatus, comprising: a control unit that converts a kana-kanji character in a phrase unit based on the dictionary memory and displays the converted character string on the display unit based on the dictionary memory. The phrase that can display all of the Kana-Kanji converted character string on the display means when there is a character confirmation operation, confirms the Kana-Kanji converted character string, and displays all of the Kana-Kanji converted character string on the display means The phrase that cannot be displayed is characterized in that a character that is not converted to Kana-Kanji is displayed on the display means.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0013]
FIG. 1 is a diagram showing a configuration of a kana-kanji conversion apparatus according to the present invention. (1) is a control circuit unit composed of a microcomputer or the like, and controls the kana-kanji conversion device based on a program written in the ROM (2). (3) is an input means, which is converted by a character key (31) such as a hiragana character or katakana character for inputting a reading, a conversion key (32) for instructing a conversion command for kana-kanji conversion, or a conversion key (32). A confirmation key (33) for confirming all the conversion candidate clauses at once is provided. Note that the input to the apparatus may be performed by voice recognition in addition to the key input. Further, for example, a partial confirmation key may be provided for confirming a conversion candidate phrase for each phrase.
[0014]
The dictionary memory (4) is composed of a system dictionary (41) prepared in the system in advance and a user dictionary (42) registered by the user for each user. The dictionary memory (4) includes independent word readings and conversion candidates corresponding to the readings. Are stored together with the score ranking data of each conversion candidate determined by the usage frequency of the user.
[0015]
(5) is an input buffer for sequentially storing readings inputted by the character key (31). (6) is a conversion buffer for storing a kana-kana mixed sentence and its phrase obtained by converting the reading stored in the input buffer (5) by the control circuit (1) by pressing the conversion key (32). (7) is a confirmation buffer for storing a kanji-kana mixed sentence confirmed by pressing the confirmation key (33). (8) is a display memory for storing a character string for displaying a confirmed kanji-kana mixed sentence or an unconfirmed kanji-kana mixed sentence. The kanji-kana mixed sentence stored in the display memory (8) is displayed. Displayed on the display unit (9).
[0016]
Next, the operation of this embodiment will be described based on the flowchart shown in FIG.
[0017]
First, when a reading character string is input from the input key (31) (Y in step S1), the input reading character string is stored in the input buffer (5) (step S2). Each time the reading character string is stored in the input buffer (5), the control circuit (1) reads the reading character string stored in the input buffer (5) and the reading character string stored in the dictionary memory (4). Are divided into compound phrases at positions where conversion candidates exist in the dictionary memory (4) and stored in the conversion buffer (6) (step S3).
[0018]
The control circuit (1) searches the dictionary memory (4) for homophones corresponding to the reading of each phrase stored in the conversion buffer (6), that is, conversion candidates, and stores them in the conversion buffer (6) (step S4). And display on the display unit (9) (step S5).
[0019]
When the conversion key (32) is pressed (Y in step S6), the conversion candidate stored in the conversion buffer (6) is deleted, the next conversion candidate is read from the dictionary memory (4), and the conversion buffer ( 6) (step S7) and display on the display unit (9) (step S8).
[0020]
When the enter key (33) is pressed (Y in step S9), all the conversion candidates stored in the conversion buffer (6) are stored in the display memory (8) and displayed on the display unit (9). (N in Step S10) is stored in the confirmation buffer (7), and the last phrase is displayed at the head of the display unit (9) (Step S11).
[0021]
In step S10, when there is a phrase that is not displayed on the display unit (9) (N in step S10), the phrase that is all displayed is stored in the confirmation buffer (7), and the confirmed phrase is displayed in the display memory (8 ) And the phrase that is not displayed at all is stored at the top of the display memory (8) and displayed on the display unit (9) (step S12).
[0022]
As a specific example, if “ji → conventional” “ka → kana kanji” “to → conversion device” is registered in the user dictionary (42), as shown in FIG. When the conversion key (32) is pressed and the conversion key (32) is pressed, conversion is performed as shown in FIG. 3 (b), and the “display of position” in the broken line portion is not stored in the display memory (8). Not displayed in (9).
[0023]
When the enter key (33) is pressed at this time, only the conversion candidate clauses ("conventional kana-kanji" in FIG. 3B) in which all the conversion candidate character strings are stored in the display memory (8) are confirmed. Store in buffer (7). Then, the conversion candidate clauses (in the case of FIG. 3 (c), “No.”) are moved to the top of the display memory (8), and the display candidate is not stored in the display memory (8). 9).
[0024]
When the conversion key (32) is pressed again, the conversion is performed as shown in FIG. 3D. When the confirmation key (33) is pressed here, the conversion ends.
[0025]
Here, the phrase that can display all of the character string on the display unit (9) is determined by the operation of the confirmation key (33), and the phrase that cannot be displayed on the display unit (9) is not fixed. However, in the operation of the conversion key (32), the phrase that can display all of the character string on the display unit (9) is kana-kanji converted, and the phrase that cannot display all of the character string on the display unit (9) is Kana-kanji conversion may not be performed.
[0026]
As described above, when the confirmation key is pressed when the conversion candidate does not fit in the display part and is not displayed during Kana-Kanji conversion, only the displayed part is confirmed, and the part that is not displayed is not confirmed. Therefore, it is possible to provide a kana-kanji conversion device that prevents the user from converting and confirming characters that are not intended.
[0027]
【The invention's effect】
According to the kana-kanji conversion device of the present invention, when the conversion key is not displayed because it does not fit on the display part at the time of kana-kanji conversion, only the displayed part is fixed, and the non-displayed part is not fixed. Thus, the user can provide a kana-kanji conversion device that can confirm the converted kanji-kana mixed sentence after confirming whether the sentence is desired.
