Abstract

PURPOSE:To perform KANA (Japanese syllabary)/KANJI (Chinese characters) conversion with a simple operation without increasing the memory capacity, by storing the conversion identifying data in the specific idle position of a memory part where the grammar data on a dictionary memory means is stored. CONSTITUTION:When a phonetical read mode is supplied with the operation of a key on a keyboard 12, this key data is sent to a CPU 1. The CPU 1 retrieves the address of a floppy disk based on said key data to read the corresponding KANJI data as well as the corresponding grammar data. Then '0' is stored in the final bit of the idle data part of No.4 of a grammar data part corresponding to the KANJI data part. Thus a KANJI display mode is shown. Thus the CPU 1 identifies said final bit to decide the KANJI display and retrieves the character pattern address of the corresponding KANJI data out of a KANJI pattern memory 6 to output it to a CRT control circuit 7.

Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a Japanese sentence input device that inputs Japanese sentences according to their pronunciation and displays sentences containing kana and kanji, and in particular, relates to a Japanese sentence input device that inputs Japanese sentences according to their pronunciation and displays sentences containing kana and kanji. It relates to a system that can display without conversion or after converting to kanji.

(Technical Background of the Invention) A Japanese text input device is equipped with a floppy disk or the like as a dictionary storage means, and reads kanji data corresponding to the reading inputted using a keyboard or the like from the dictionary storage means and CR.
Text is displayed on the T-display, etc.

FIG. 5 shows a memory map of the dictionary storage means, and as shown in FIG. 5(a), a plurality of data blocks N
The memory area is divided into o, l to no, and n. Each data pro-ac consists of multiple records and free space, as shown in Figure (B), and each record has multiple candidate kanji areas corresponding to homophones, as shown in Figure (C). It is divided into Then, each candidate kanji area is shown in the same figure (
As shown in (d), it consists of a kanji data section in which homonym kanji data is stored and a grammatical data section in which grammatical data thereof is stored.

By the way, when the reading ``Jufun'' is inputted from a keyboard, etc., in the case of kana-kanji conversion processing, storage means such as 1-memory are searched, and, for example, the kanji data for ``Jufun'' is selected, and the data is sent via the character generator. The kanji for ``sufficient'' is displayed on the screen of a CRT display, etc.

(Problems in the Background Art) On the other hand, when displaying the Hirakana "Jibun", conventionally, the Hirakana data and its grammatical data for "Jibun" are stored in a dictionary storage means in advance, and the Hirakana data is I was trying to search for . However, since there are many homonyms in Kuchikimoro, if you store more hiragana data such as "jubun" and its grammatical data, the number of words to be memorized increases accordingly, so a dictionary storage device with a large storage capacity is required. It will be.

According to the non-conversion processing method of displaying only kana characters without converting the reading input into kanji characters, there is no need to store hiragana data, etc. in the dictionary storage means, and therefore it is possible to prevent the storage unit ψ from increasing. However, this method has problems in terms of operability, especially when converting continuous clauses, as it is necessary to move the cursor to the correction IE position, set the correction range, and then input the corrected kanji word again. have.

(Object of the Invention) An object of the present invention is to provide a kana-kanji conversion method that does not increase the number of words stored in a dictionary storage means and can improve operability.

(Summary of the Invention) The present invention has been made by focusing on the fact that there is an empty storage section for grammar data in a dictionary storage means, and stores conversion identification data by setting a bit in the empty storage section, etc. Based on this conversion identification data, a kanji code such as ``sufficient j'' corresponding to the grammar data is displayed in kana or normal kanji.

(Embodiments of the Invention) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing the configuration of a Japanese text input device to which the kana-kanji conversion method according to the present invention is applied.

In the figure, l is a CPU, and the CPU is connected to a main memory 3 and a floppy disk 4 via a memory bus 2.
are connected. In addition, CPU1 has I10 bus 5.
A keyboard 12, a kanji pattern memory 6 (character generator), a CRT; t, 11 control circuit 7, and a printer control circuit 9 are connected via. The CRT control circuit 7 includes a CRT display 8 and a printer control circuit 9.
A printer lO is connected to each of the . and,
The CRT control circuit 7 and the printer control circuit 9 are connected to the output side of the Kanji pattern memory 6 via another memory bus.

The floppy disk 4 stores a dictionary, and the main memory 3 stores a kanji pattern memory 6, a program for searching the characters stored on the floppy disk 4, an algorithm for kana-kanji conversion, and the like.

Next, regarding the kana-kanji conversion method according to the present invention, the above CP
The explanation will be based on the control operation of the UI.

That is, as shown in FIG. 3, when the reading ``Jibun'' is input by key operation on the keyboard 12,
This key data is transferred to the CPUI. The CPU searches the address of the floppy disk 4 based on this key data, and reads, for example, the ``r-sufficient'' kanji data and the corresponding grammar data.

By the way, the grammar data section corresponding to the kanji data section has a 4-byte structure, for example, as shown in FIG.
Grammar data such as adjective verbs and adverbs are stored in the data sections o, 1-No., and 2, and the data section N014 is not used, and in the kanji data section corresponding to the "sufficient" kanji data, No flag is set in the final bit of the No. 4 data portion, that is, it is held at "O".

Therefore, the CPU determines that the last bit of the grammar data corresponding to the "sufficient" kanji data is "0", that is, it is a kanji display, and searches the kanji pattern memory 6 for the character pattern address of the "to-bu" kanji data, CRT control circuit 7
Output to. The CRT control circuit 7 reads the character pattern from the kanji pattern memory 6 based on this address,
Low brightness (temporary) kanji for “part” on CRT display 8
indicate. In this case, the operator decides that the kanji for "sufficient" is to be displayed as a word, and presses the button on the keyboard.
When the selection key is pressed, the CPU 1 outputs a display signal to the CRT control circuit 7 to execute the selection. Therefore,
On the CRT display 8, the kanji ``sufficient'' is finally displayed with normal brightness.

On the other hand, when the key data for the next candidate search is input through the keyboard 12, the CPU 1 searches the address of the floppy disk 4, reads the "compound" kanji data as the next candidate kanji data, and uses the character pattern Search the address from the kanji pattern memory 6, and
Output to control circuit 7. The CRT control circuit 7 reads the character pattern as shown on the screen using this address, and
"Important" kanji characters are displayed at low brightness in the input area of the T-display 8. In this case, as shown in FIG. Yes.

Furthermore, when the operator determines that the ``compound'' kanji is to be displayed as a word and presses the selection key on the keyboard 12, the ``upper'' kanji displayed at low brightness is changed to the ``compound'' kanji with normal brightness. In addition, when the operator presses the selection key when the last bit of the grammar data section is rlJ, the CPU sets this final bit to rQJ, converting the low-intensity "sufficient" kanji to the normal-brightness degree "heavy text" kanji. change.

Further, when the key data for the previous candidate search is input using the keyboard 12, as shown in FIG. 4(B), the CPU
searches for the address 4 on the floppy disk 4, reads, for example, "sufficient" Kanji data as 1m candidate Kanji data, searches for the character pattern address from the Kanji pattern memory 6, and outputs it to the CRT control circuit 7. In the input area of the CRT display 8, the kanji "sufficient" is displayed with low brightness. The final beef 1 in the corresponding grammar data section is rQJ, and when the operator presses the selection key on the keyboard 12, the CPU performs a control operation to change the low-brightness display "sufficient" kanji to the normal brightness "sufficient" kanji. do. When the operator presses the selection key when the last bit of the corresponding grammar data field is "1", the CPU 1 returns this last bit to "O", and similarly changes the low-brightness display of the "sufficient" kanji to the normal-brightness display of "sufficient". A control operation is performed to change the characters to ``sufficient'' kanji.

Now, when the operator decides that the kanji "sufficient" displayed in low brightness on the CRT display 8 should be displayed in kana and presses the non-conversion key on the keyboard 12, the CI'U1 will be displayed as shown in FIG. 4(C). Then, the final bit of the corresponding grammar data section is set, rlJ is set as shown in FIG. 2, and a kana display control signal is output to the CRT control circuit 7. Therefore, on the CRT display 8, the low-brightness kanji character "sufficient" is changed to kana "sufficient" and displayed at normal brightness.

Next time, the operator will read “Enough”.
is input, and when the CPU 1 reads the "sufficient" kanji data from the floppy disk 4 and also reads the corresponding grammar data, the last beat 2 of the grammar data section is set to "1", so The CPU determines that this final bit is rlJ, and controls the CRT control circuit 7 to automatically display the kana word ``sufficient'' on the CRT display 8 at low brightness. Therefore, when the operator decides to continue displaying kana and presses the no-conversion key, as described above, the CRT display 8F:.

The word "sufficient" for normal brightness is displayed.

Also, when you select the next candidate or the previous candidate and press the no conversion key, the CPU determines that "complex sentence" or "sufficient" is displayed in kana, and the last bit of the corresponding grammar data is r
lJ, and a control operation is performed to display "sufficient" in kana on the CRT display 8. Therefore, from now on, unless the final bit is changed to "0", the "authentic text"
Or "sufficient" is automatically displayed in kana "sufficient" in low brightness.

Note that if all of the next or previous candidates are selected and the target kanji does not exist, the CPU displays the input reading as it is in kana.

” - In the embodiment described above, rlJ is added to the last bit of the grammar data part.
The key is to set a bit at a specific vacant position.

(Effects of the Invention) According to the present invention, change identification data is stored by setting a flag (bit) in a specific vacant position of the storage section in which grammar data is stored in the dictionary storage means, and based on this conversion identification data. By automatically displaying the reading input in kana or kanji, kana-kanji conversion can be performed with a simple operation without increasing the storage capacity of the dictionary storage means.
