Abstract

PURPOSE:To obtain a Japanese word input device with which the input time can be greatly reduced by using a means which displays some of the words used in the past on a picture plane with limitation and then designates these displayed words in a simple way. CONSTITUTION:A KANA (Japanese syllabary) character C supplied throgh a KANA input part 1 is stored to an input KANA string temporary storage part 2 and then delivered to the 2nd word retrieving part 5 through a KANA/KANJI (Chinese character) conversion part 15. The part 12 delivers the KANA string to the 1st output desplay part 6 in the form of a symbol character string K2 if a symbol character string K3 obtained through the retrieval of words shown the absence of the corresponding word. When a redisplayed word designation signal S8 is supplied to the 3rd word retrieving part 12 from a selection signal input part 14, a corresponding symbol character string K4 is obtained out of the 3rd word storage part 11 and delivered to the part 6. The part 14 delivers a word deciding signal S5 to the part 15 when a word decision key is pushed. Then the part 14 delivers the string K2 which is under display to a registration deciding part 10 and delivers the K2 if a symbol equal to the K2 exists.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a Japanese character input device for inputting kanji-kana mixed sentences in kana.

Conventional Structure and Problems There has recently been an active development of Japanese character input devices that input Japanese documents in kana. Among them, 1
A device has been devised in which words that appear once during document input are memorized and are treated with priority in subsequent processes such as homophone selection.

FIG. 1 shows a block diagram of an example of a Japanese character input device incorporating such a device. Here, 1 is a kana input section where 1 Japanese characters such as katakana and hiragana are inputted as :l-)'. Reference numeral 2 denotes an input kana string temporary storage section which temporarily stores kana C sequentially inputted from the one kana input section as an input kana string C1, and outputs it to a kana-kanji conversion section to be described later. The contents of the temporary input kana string storage section 2 are cleared by a signal S1 from the kana-kanji conversion section, which will be described later. 3 is a first word search unit which receives a kana string C1 and a next word selection signal S2 from a kana-kanji conversion unit (described later), and sets 1 to the written character string of the word and its homophones stored corresponding to C1. Output. 4, when a word is selected in the second word storage section, 2 and the kana string C1 are sequentially stored in the internal storage area in the written character string received from the kana-kanji conversion section, which will be described later. Furthermore, when the storage area becomes full, data is stored again from the beginning of the storage area, realizing a so-called first-in, first-out mechanism. Furthermore, the address A1 within the storage area of the word stored immediately before is separately stored. Reference numeral 6 denotes a second word search unit which receives a next word designation signal S6 and a kana sequence C1 from a kana-kanji conversion unit to be described later, and searches the second word storage unit from the previous storage address A1 or from the previous search word address A2. A word having a pronunciation matching the input kana string C1 is searched for by changing the word address sequentially. This address A2 of the previous search word is stored inside the second word search section. 6 is the first output display section, which will be described later.
-Display 2 in the notation string received from the converter. γ
The kana-kanji conversion section receives a system activation signal s3, a next candidate selection signal S4, and a selection signal input section to be described later. Word determination signal Ss - Receives the input kana string C1 from the input kana string temporary storage section.

Among these, in response to the input of S3, a clear signal S1 is output to the input kana string temporary storage section to erase its contents. Also C1
Alternatively, in response to the input of S4, it outputs the kana string C1 and the conversion start signal S6 to the second word search section, and receives 3 for the corresponding written character string.

It also outputs C1 and a conversion start signal S2 to the second word search section, and receives 1 for the corresponding kanji string. The kana-kanji conversion unit displays 1°K6 in order on the first output display unit. In response to the input of the word decision signal S5, 2 is output as the current output word to the second word storage section, and registered in the second word storage section, and then a signal is sent to the input kana string temporary storage section. Output S1 and clear its contents.

Reference numeral 8 denotes a selection signal input section which outputs a system activation signal S3, a next candidate selection signal s4, and a word determination signal S5 to the kana-kanji conversion section. 9 is the first word storage unit, which stores word pronunciations and written character strings in association with each other.9.7.-
It is assumed that the data is stored in a secondary storage device such as a hard disk.

The operation of the conventional Japanese character input device constructed as described above will be explained below with reference to the flowchart shown in FIG.

〔Start process〕

(1) When the system activation key is pressed, the selection signal input section 8 sends a system activation signal S3 to the kana-kanji conversion section 7. Next, the kana-kanji conversion section 7 outputs a kana string deletion signal S1 to erase the contents of the input Canadian 1 time storage section 2, and enters an input waiting state.

[Conversion process]

(2) When a kana character C is input from the kana input section 1, it is sequentially stored in the input kana string temporary storage section 2 as an input kana string C1.

(3) When the input kana string C1 is input from the input kana string temporary storage section 2, the kana-kanji conversion section 7 first outputs C1 to the second word search section 6 and stores it in the second single-j character memory. The word address is changed sequentially from A1 in section 4 to search for a word whose pronunciation matches 01, and when -86 is input, a search is performed from the previous search address person 2 and a new A2 is set.

(4) If the written character string obtained as a result of the word search is a character string in which 3 represents ink without a corresponding word, the kana-kanji conversion unit 7 controls the process to proceed to (5), otherwise proceeds to process (8). move.

(6) The kana-kanji conversion unit 7 first determines whether C1 has been input from the input kana string temporary storage unit 2. If C1 has been input, it outputs C1 to the first word search unit 3. . - When the next candidate selection signal S4 is input from the power selection signal input section 8, the next word selection signal S2 is input to the first word search section 3.
Output to , and get 1 for the corresponding notation string.

(6) If the notation character string obtained as a result of the word search is a character string in which 1 indicates that the corresponding word does not exist, the kana-kanji converter 7 goes to (a) - otherwise, control is transferred to (8).

(7) The kana-kanji part conversion 7 outputs the kana string C1 inputted from the input kana string temporary storage section 2 as a notation character string 2 to the first output display section 6, and enters an input waiting state.

(8) If there is a reused notation character string represented by 5, the kana-kanji conversion unit 7 outputs 3 to the output display unit 6 as a candidate notation character string of 2, and if there is not, the initial usage notation represented by 1 is output. The character string is set to 2 and is output to the output display section 6, waiting for input.

[Word specification processing]

(9) When the word selection key is pressed, the selection signal input section 8 outputs the word determination signal S5 to the kana-kanji conversion section 7.

(til+ When S5 is input, the kana-kanji conversion unit 7 registers 2 and the kana string Gi in the word currently being output in the first-in, first-out storage unit in the second word storage unit 4.〇(11) Kana-kanji The conversion section 7 sends a kana string deletion signal S to the input kana string temporary storage section 2.
1 is output to clear the input kana string temporary storage section 2 and enter the input waiting state.

[Next candidate selection process]

(When the next candidate selection key is pressed, the 121 selection signal input unit 8 outputs the next candidate selection signal S4 to the kana-kanji conversion unit 7,
Transfer control to (3).

FIG. 3 shows the display contents of the first output display section 6 during the input of Japanese text using this device. FIG. 4 shows the contents of the second word storage section 4 at that time. At this point, if the operator wishes to input the notation character string "Koji", the operator inputs the kana string "Koraziyo" from the kana input section 1. The kana-kanji conversion unit 7 outputs the kana string to the second word search unit, but as a child can see in FIG. Therefore, the kana-kanji conversion unit 7 outputs the kana string C1 to the first word search unit 3, and searches the first word storage unit configured on the primary storage device.

As a result, 2 is displayed as the candidate word on the first output display section 6, and the state is set to wait for input. Kypeleta is the desired word “improvement”
Press the primary candidate selection key until you obtain . When the operator presses the selection key when the result is "improvement", the kana-kanji converter 7 registers the kana string and the notation character string "improvement" in the second word storage section 4, and inputs the input kana character string. A kana string deletion signal S1 is output to the temporary string storage section 2 to clear the input kana string temporary storage section and return to the input waiting state.

Next, consider a situation in which the word "improvement" is input again after that point.

FIG. 6 shows the display contents of the first output display section 6 at a certain point in time while inputting Japanese text using this device, and FIG. 6 shows the contents of the second word storage section 4. When the kana string "Korajiyo" is input from the kana input section 1, the kana-kanji conversion section 7 receives the kana string via the input kana string temporary storage section 2 and outputs it to the second word search section 5. The second word search unit 6 sequentially compares and searches the second word storage unit 4 starting with the previously registered word address person 1. As shown in Figure 6, A1 at this time is 6, so we compare one word address 6 "Shinraisei" to 6 "Daikai" in order, and find a word that matches "Korajyou" at word address 3.
Set A2 to 3.

The notation character string “Kiyo” is returned to the kana-kanji conversion unit 7.

The kana-kanji conversion section 7 outputs "Kai" to the first output display section 6 and enters an input waiting state.゛By providing the second word storage unit 4 in this way, the previously selected word can be efficiently retrieved from the homophone series output from the first word search unit 3 without accessing the secondary storage device. You can choose.

However, with the above structure, there is a problem that when different homophones appear in the same sentence, such as ``Conductor Concerto Four Seasons,'' it is not possible to obtain the desired word as the first candidate. had. You can also remember the history of selected words when recalling the desired word.

It was necessary to input the corresponding pronunciation each time. In other words, even though inputting effort can be saved, it is only a slight reduction in the number of homophone selection operations.

OBJECT OF THE INVENTION The present invention solves the above-mentioned problems of the conventional Japanese character input device, and displays a limited number of words that have been used in the past on the screen - and allows them to be easily specified. The purpose of the present invention is to provide a Japanese character input device which can greatly reduce the input effort by providing a means for inputting characters.

The operation of the Japanese character input device of the Honjibushireri constructed as described above will be explained below with reference to the flowchart shown in FIG.

〔Start process〕

(1) When the system activation key is pressed, the selection signal input unit 14 outputs a system activation signal S5 to the kana-kanji conversion unit 16. Then, the kana-kanji conversion section 16 outputs a kana string deletion signal S1, erases the contents of the input kana string temporary storage section 2, and enters an input waiting state.

[Conversion process]

(2) When the kana character G is input from the kana input section 1, it is sequentially stored in the input kana string temporary storage section 2 as the input kana string C1.

(3) The kana-kanji conversion section 16 first determines whether the kana string C1 has been input from the input kana string temporary storage section 2. C
If 1 is input, C1 is output to the second word search section 6. On the other hand, the next candidate selection signal S4 is sent from the selection signal input section 14.
When input, the next word selection signal S6 is sent to the second word search unit 5.
Output. The second word search unit 5 uses the immediately preceding storage address A1. A search is performed from the previous search unit address A2, and if there is a word that matches C1, 5 is returned to the notation literature string of the corresponding word, and the previous search word address A2 is updated.

(4) If the written character string obtained as a result of the word search has 3 indicating that the corresponding word does not exist, the kana-kanji conversion unit 16 proceeds to (6), otherwise the control shifts to f8).

(6) The kana-kanji conversion unit 16 first determines whether C1 has been input from the input kana string temporary storage unit 2.

In the case of 01 input, C1 is output to the first word search unit 3 and 1 is obtained as the character notation of the corresponding word. One selection signal input section 1
When the next candidate selection signal S4 is inputted from 4, the next candidate selection signal S2 is outputted to the first word search section 3, and 1 is obtained as the notation character string of the corresponding word.

(6) The kana-kanji conversion unit 16 converts the character string if 1 indicates that there is no corresponding word in the notation character string (if it is - to power, then (8
) transfers control to processing.

(The kakana-kanji conversion section 16 outputs the kana string input from the input kana string temporary storage section 2 as a notation character string 2 to the first output display section 6, and enters an input waiting state.

(8) If there is a 5 in the written character string obtained from the second word search unit, the kana-kanji conversion unit 16 sets 3 as the candidate written character string and outputs it to the first output display unit 6. It outputs 1 as 2 to the notation obtained from the word search section of 1, and enters the input waiting state.

(9) When the next candidate selection key is pressed, the selection signal input unit 14 outputs the next candidate selection signal S4 to the kana-kanji conversion unit 15, and the control is transferred to 3).

It outputs a hekana string deletion signal S1 to erase its contents and enters an input waiting state.

FIGS. 9, 10, and 11 show the first and second output display sections 6, 13 and the second word storage section 6. This represents the contents of the third word storage section 11. Let us consider the case where a new word ``improvement'' is entered at this point. When the kana string "Korajiyo" is input from the kana input section 1, the kana-kanji conversion section 1
6 receives the kana string via the input kana string temporary storage section 2;

First, 01 is output to the second word search section 5. As can be seen in FIG. 10, since there is a character string matching address 2 in the second word storage section 4, the second word search section 5 searches for "
"Improvement" is returned to the kana-kanji conversion unit 16 as ni3. Since the kana-kanji conversion unit 16 has 3, it outputs this to the first output display unit 6 and enters a waiting state. Since the output word is the desired word, the operator presses the word determination key to approve it. Then, the kana-kanji conversion unit 16 that received the word determination signal S5 outputs "improvement" to the registration determination unit 10, and the second word storage unit 4
Search for this within. Since there is a corresponding word, registration judgment part 1
○ outputs “improvement” to the third word storage unit 11. The result is as shown in FIG. Next, kana-kanji conversion section 15
After registering "korajyo" and "improvement" in the second word storage section 4, the input kana sequence temporary storage section 2 is cleared and the machine enters the waiting state again.
