Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana-kanji conversion device.

[0002]

2. Description of the Related Art A conventional kana-kanji conversion device realizes efficient kana-kanji conversion by combining a idiom dictionary and a single kanji dictionary. However, when the memory capacity is limited, it is also possible to perform kana-kanji conversion using only a single kanji dictionary without having a idiom dictionary.
When using only a single Kanji dictionary, for example, to obtain the conversion result of "Utatsu", search for a Kanji candidate from the reading of "U", select "Utatsu", and convert "Tsu" without conversion. To do.

By the way, in a single-kanji conversion device using a single-kanji dictionary, the single-kanji candidates are displayed in a line on the assumption that one kanji candidate for reading is one kanji (single kanji). A device for performing the above is considered.

Further, although there is a display frame that has only one line for cost reduction, in such a device, when a candidate for a Chinese character is displayed, the reading display is erased and the candidate is displayed.

[0005]

However, when, for example, inputting "protect", "Mamoru" is input and a conversion instruction is given, but there is also a candidate for "Mamoru" for which there is no delay. There is also a nature. In such cases,
As described above, if the display frame is narrow, the reading candidates are erased, so the candidates displayed after the conversion instruction are retrieved from the "Mamoru" reading or the "Mamo" reading. There was a problem that I didn't know what it was. Therefore, when converting to "It is important to keep the rules", etc., if you make a mistake and confirm with "Mamoru", you must convert all the unconfirmed parts of "Kotometsutsu" and then "Ru". It was troublesome to add.

In addition, when inputting "meeting", "meeting", "meeting", etc. may be displayed as the conversion result. Therefore, when converting to kanji, if it is not confirmed, what is the conversion target. It was inconvenient because I didn't know what it was.

The present invention has been made in order to solve the above-mentioned problems. When converting Kanji, the input character string is displayed in such a form that the target character string can be discriminated. It is an object of the present invention to provide a kana-kanji conversion device characterized by being able to confirm.

[0008]

Means for Solving the Problems] kana-kanji conversion apparatus of the present invention to achieve this object, an input unit for inputting a kana character string, and storage means for storing the Do string or the the input, storage and conversion processing means for converting the Do string or stored in unit to a single Chinese character, a candidate display means for displaying a single Kanji candidate by the conversion processing unit, with the candidate Chinese characters are displayed, the storage means a conversion target display means for displaying Do string or conversion of the processing target in the single Chinese character by the conversion means of the Do <br/> string or stored by switching from candidates displayed by the conversion target display means display
The converted kana character string to be converted is displayed as the candidate.
It includes a returning means for returning and a selecting means for selecting and confirming the candidate of the single Chinese character.

The conversion target display means may include display time control means for displaying the kana character string stored in the storage means only for a fixed time.

Further, the converted display means, when displaying Do string or conversion of the processing target in the single Chinese character by the conversion means of the Do string or stored in the storage means, said conversion processing means A display form changing means may be provided to display only the kana character string for the single-kanji candidate processed by the above method in a display form different from that of the other character string portions.

[0011]

In the kana-kanji conversion device of the present invention having the above structure, when a kana character string is input by the input means,
The storage means stores the input character string. The conversion processing means searches for a single kanji character corresponding to the kana character string stored in the storage means, and the candidate display means displays the searched single kanji character candidates. In the state where the candidates are displayed, the conversion target display means switches and displays the kana character string that is the conversion target from the candidate display. Return hand stage is displayed by the conversion target display means
The converted kana character string that has been converted is returned to the candidate display.
You The selection means selects the kanji in the state where the kanji candidate display is returned again, and acquires the desired converted character string.

The display time control means displays the kana character string by the conversion target display means for a certain period of time. For this reason, after the conversion target character is displayed, the display returns to the display state of the candidate single kanji, so that the kanji can be fixed or the reading character string can be re-cut immediately.

[0013] In addition, the display form changing means, when displaying Do string or stored in the storage means, only the Do string or for the candidate Chinese characters and other parts to vary the display mode. By doing so, the front-back relationship can be easily understood.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is an example of display on a display. Also,
3 and 4 are flowcharts provided for explaining the operation of this embodiment.

As shown in FIG. 1, the kana-kanji conversion apparatus according to the present embodiment has a keyboard 20 which is an input means for inputting an instruction such as a reading character string and printing, a display 30 for displaying an input character string and a graphic, The printer 40 includes a printer 40 that prints an input character string, and an electronic control device 50 that is connected to the printer 40 to control input / edit / print of a document. The display 30 has a display area of one line.

The keyboard 20 is a key for inputting kana characters and numbers, a conversion key for giving an instruction to convert the input kana character string into a single kanji character, and executing various operations such as fixing the kanji character selected at the time of conversion. There are an execution key for performing, a cursor key for moving the character input position in the document and selecting a single Kanji character during conversion, and a switching key for instructing the switching of the display. When operated, the electronic control unit 50 is instructed to input, convert, edit, and print the document.

The electronic control unit 50 is a central processing unit (CP).
U) 60, ROM 70, RAM 80, etc. are mainly configured as an arithmetic and logic operation circuit, and an input port 90 for converting an input / output signal of an external device such as the keyboard 20 into a signal which can be processed by the CPU 60 is provided.

The ROM 70 is provided with an area 72 for storing a single kanji dictionary data used in this conversion processing, in addition to an area for storing a kana-kanji conversion processing program. Each record stored in the dictionary data storage area 72 stores a reading character string (kana) and a notation (kanji) corresponding thereto.

The RAM 80 is provided with a character string storage area 82 for storing a kana character string input from the keyboard 20 and a work area 84 used for kana-kanji conversion processing. The character string storage area 82 corresponds to the storage means of the present invention.

Next, the operation of this embodiment configured as described above will be described with reference to the flow charts of FIGS. 3 and 4.

First, a kana character string is input (step S41). Here, as an example, description will be given assuming that a character string “to protect” is desired to be obtained. First, the character string “to protect” for conversion is the keyboard 20.
Input with the character keys of. The input character string is stored in the character string storage area 82 (step S43), and the input character string is also displayed on the display 30 as shown in FIG. 2a (step S45).

When the conversion key is pressed in the state where the input character string displayed as in step S45 exists (steps S47 and S49; YES), the character string is cut out as "protected" by the well-known longest matching method. , A single kanji corresponding to the reading of "Mamoru" is searched. At this time, the pointer is moved to the last position (last kana character) of the cut out character string, and the position is stored in the character string storage area 82. The cut out character string to be converted (in this case, "Mamoru") is stored in the work area 84 (step S61). The longest matching method used in this Kanji conversion is a known method for selecting a notation having a reading that matches the longest character string from the front among the input character strings.

When the series of processes in step S61 as the conversion processing means is completed, the input character string on the display 30 is erased, and the retrieved candidate single kanji is displayed as "guard, guard, guard, guard, ..." as shown in FIG. 2b. Are displayed in order (step S63). The process of step S63 corresponds to the candidate display means.

When the switching key for instructing display switching is pressed while the candidate for Kanji is displayed (steps S65 and S71; YES), the character string storage area 8 is displayed.
The input character string stored in 2 is displayed as in FIG. 2c (step S75). At this time, from the beginning of the undetermined portion of the displayed input character string to the pointer position (the portion of "Mamoru") is displayed in reverse video as the conversion target.
If the cancel key is pressed here (step S76; YE
S), and the display returns to the kanji candidate display again (step S63). If the cancel key is not pressed in the display state of step S75 (step S76; NO), the input character string is kept displayed. Here, the reverse display makes the conversion target character string have a different display form from the other character string portions, and this portion corresponds to the display form changing means of the present invention. In addition to the reverse display, blinking display, underlined display, or any other display is possible as long as the display form is different. Note that step S
Reference numeral 75 corresponds to conversion target display means.

If there is a desired Kanji character candidate displayed in step S63, the selection candidate is moved with the cursor key of the keyboard 20 or the like, and "Mamoru" is selected with the execution key (step S67; YES). When the Kanji is selected with the Enter key, the display of Kanji candidates ends, and "Kanji <Koto>" is displayed.
The selected kanji is displayed with the remaining undetermined part shown in <> left behind (step S7).
9). At this time, the last pointer position of the undetermined part stored in the character string storage area 82 is stored as the head of the undetermined part this time (step S54). Step S
The series of processing from 63 to step 54 corresponds to the selecting means of the present invention.

However, when "Mamoru" is selected in the state where "Mamoru" is selected as a reading as described above, "Ru" which is a kana to be sent is also included in the reading, and after confirmation, Since it is a "protection", if necessary, reread the reading here.

When the key for instructing re-reading of the reading (conversion target) is pressed (steps S65 and S73; YE
S), re-reading is performed (step S74), the conversion target is only "Mamo", and candidates for kanji for "Mamo" are displayed (Step S61), so "Mamoru" is selected from there. Yes (step S67). Figure 2d after selection
Is displayed as "Protect" (step S7)
9).

Next, since the undetermined character string is not yet finished (step S55; NO), step S47 is executed again.
Wait for key input with, but if you press the non-conversion key with the cursor on "ru" (step S4)
9; NO and S51; YES), "ru" is confirmed as hiragana, and the notation "protect <koto>" is obtained (step S53).

However, the undetermined character string "<koto>"
Remains (step S55; NO), the process returns to step S47 again and waits for key input. Where step S
If the "character" is fixed without conversion by repeating steps 51 to S55, the character string after the fixing "protect" can be obtained (step S55; YES), and the conversion of the input character string is ended.

If it is desired to print the displayed character string after the conversion of the input character string is completed, the printer 40 can print by pressing the print key of the keyboard 20.

When the cancel key of the keyboard 20 is depressed in step S65 (step S69; YE)
S), the candidate display is erased (step S77), and the state returns to the state of displaying the input character string in step S45. In step S65, the enter key, the cancel key, the switch key,
When a key other than the rereading key is pressed (steps S67, S69, S71, S73; NO), the display does not change as an invalid key.

In step S47, the conversion key
If a key other than the non-conversion key is entered (step S
49; NO and S51; NO), other processing is performed according to the instruction of the key (step S57). Other processing includes deleting the last character when the delete key is pressed.

In the present embodiment, when the input character string is displayed in step S75, it is displayed until the cancel key is selected, but it is also possible to return to the candidate display by pressing the display switching key again. Also, step S7
After the input character string displayed in 5 is displayed for a certain period of time, the display may automatically return to the candidate display. In that case, a soft timer counts a predetermined time and the display is switched to the candidate display after the count ends. do it. In this way, it is possible to provide the display time control means (soft timer).

Further, in the present embodiment, when the input character string is displayed in step S75, all the input character strings are displayed in the form in which the character string to be converted is displayed in reverse video. Thus, of the stored character strings, only the portion to be converted may be displayed.

[0036]

As is apparent from the above description,
Since the kana-kanji conversion device according to claim 1 of the present invention can confirm in advance what kind of syllabary notation will be used when converting a kana character string that can be used with or without syllabary, After conversion, the character string of the desired notation can be obtained immediately, and it is possible for the user to proceed smoothly without the trouble of modifying after conversion.

Further, the kana-kanji conversion apparatus of claim 2, since the Do string or has become converted automatically returns to the candidate display after being displayed for a certain time, it is possible to also proceed smoothly .

In addition, the kana-kanji conversion device according to claim 3 can judge what kind of feed is to be made by looking at the context, so that the conversion work can be performed in a more understandable manner.
