Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an English translation machine that translates, for example, English text into Japanese text.

In recent years, electronic translators have been developed that translate key-input English words into Japanese or Japanese into English. This type of electronic translator generally has
A dictionary memory is provided that stores English words and their Japanese translations as a pair, and when an English word is input from the key input section, the Japanese translation of this English word is searched and read out from the dictionary memory, and the display section reads out the Japanese translation of the English word. Alternatively, when Japanese is input from the key input section, the dictionary memory is searched for the English corresponding to the Japanese and the result is displayed on the display section. Therefore, this type of electronic translator only has the function of an electronic dictionary for simply translating key-input words, but does not have the function of translating sentences. Electronic translators have also been proposed that have the function of translating sentences, but in the case of these electronic translators, they simply replace each word in a sentence with a translated word. For example, this is a pen ↓ Coreha death human horn pen.

It has the disadvantage that it can only perform such translations, and it is not a complete translation.

This invention was made under the above-mentioned circumstances, and its purpose is to provide an English translation machine that can obtain translations of Japanese sentences into English sentences in accurate word order using an extremely simple method. be.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a circuit diagram of the main parts of the electronic translator of this embodiment. Key input section 1 includes alphanumeric keys (not shown) for inputting English words, and when inputting English words, whether the English word is a subject, predicate verb, indirect object, direct object, or complement. S to distinguish and input whether it is applicable
(subject) key, V (predicate verb) key, DO (direct object) key, IO (indirect object) key, C (complement) key, translation (translation instruction) key, clear key (not shown), etc. is provided. A key input signal from each key of the key input unit 1 is sent to a key encoder 2 and encoded, and the type of each key is determined. Therefore, the key input signal of the alpha key is converted into the corresponding code by the key encoder, and the key input signal of the S key, V key, IO key, DO key, and C key is converted into the code S, code V, and code V, respectively. The key input signals of the translation instruction key and the clear key are converted into code IO, code DO, and code C, and are further converted into a translation instruction signal and a clear signal, respectively, and both are given to the sentence pattern discrimination circuit 3. The sentence pattern determination circuit 3 is a circuit that determines which of the five types of English sentence patterns corresponds to the sentence pattern of the English sentence inputted using the alphanumeric key, S key, V key, IO key, DO key, and C key. be. The five types of sentence patterns are shown below. In addition, the subject, predicate verb, indirect object, direct object, and complement are respectively designated by symbols S, V,
Indicated by IO, DO, C.

The search circuit 5 is a circuit that searches a dictionary ROM (read only memory) 11 for the Japanese translation of each word constituting the English sentence inputted from the key input section 1 and reads it out. In this case, the search circuit 5
drives the address specifying section 12 and reads the dictionary ROM 11.
The addresses of the dictionary ROM are specified sequentially.
English words are sequentially read out from 11 and given to the search circuit 5. The search circuit 5 constantly compares the input English word with the English word read from the dictionary ROM 11, and when the two match, the search circuit 5
is configured to stop the above-mentioned search operation. In the dictionary ROM 11, English words and their Japanese translations are stored in pairs at the same address. The English word and its translation searched by the search circuit 5 are then sent as a pair of information to the corresponding subject register 6, predicate verb register 7, indirect object register 8, direct object register 9, and complement register 10. input to either. 6A to 10 of each register 6 to 10 above

It is configured to output C2.

The data in the display buffer 13 is given to the character generator 14 and converted into corresponding character pattern data, and this character pattern data (parallel data) is converted into serial data by the P/S converter 15 and then displayed on the liquid crystal display. It is displayed in section 16.

When the determination signal is being input, that is, when the input English sentence is determined to be of the first sentence type, read signals S2 and V2 are generated in this order. Further, when the discrimination signal (second sentence pattern) is being input, read signals S2, C2, and V2 are generated in this order.

Next, the operation of the above embodiment will be explained. Now, the first
When inputting ``Birds fly.'' as an example sentence pattern and translating it, the alphanumeric key, S key, V key, and translation instruction key on the key input section 1 are operated in the following order. Note that the plural form of the noun shall be converted into the singular form and input.

Bird, □S, fly, □V, □ translation In the above key operation, the word "Bird" is converted into a corresponding code by the key encoder 2 and input to the buffer 25 in the sentence pattern discrimination circuit 3. When the S key is operated, a code S is output from the key encoder 2 and is applied to the decoder 22 via the OR gate 20, the area A of the register 21, and the OR gate 23. Therefore, the decoder 22 outputs the write signal S1 and gives it to the subject register 6,
Further, the code S is stored in area A of the register 21, and furthermore, the output of the OR gate 23 becomes "1" and the AND gate 24 is opened. Accordingly, the English word "Bird" in the buffer 25 is changed to 24 and applied to the search circuit 5. The search circuit 5 starts a search operation for the English word "Bird", drives the address specifying section 12, and searches the dictionary ROM 11. Then, when the English word "Bird" and the translated word "tori" are detected for the word data "Bird" from the dictionary ROM 11, the English word "Bird" is detected in the area 6 of the subject register 6 where the write signal S1 is being output.
A, and at the same time, the translated word "tori" is written in area 6B.

Similarly, the English word "fly" is input into the buffer 25. Also, by operating the V key, a write signal V1 is output from the decoder 21 and the predicate verb register 7
Further, the code V is stored in area B of the register 21, and the English word "fly" is supplied to the search circuit 5 to execute its search operation. When the search is complete, the English word "fly" and its translation "tobu" for the English word "fly" are stored in the predicate verb register 7.
are written in areas 7A and 7B, respectively.

Next, by operating the translation key, a translation command signal is output, and is applied to the code generation section 26 and the sequential pulse generation circuit 43. Therefore, codes S, V, C, DO, and IO are outputted from the code generation section 26, respectively. Further, the sequential pulse generation circuit 43 sequentially generates pulses P ₁ , P 2 , P 3 , P 4 from its output terminals 1, ₂ , ₃ , and _4.
will start outputting in this order. In the sentence pattern discrimination circuit 3, the register 21 has areas A and B.
Since the codes S and V are input to the respective circuits, only the outputs of the matching circuits 27 and 29 are both “1”.
Therefore, the output of the AND gate 28 becomes "1". Further, since the output of the NOR gate 42 is "1", both of the two inputs of the AND gate 30 become "1", and only the output, that is, the discrimination signal is outputted and applied to the word order selection circuit 4.

On the other hand, in the word order selection circuit 4, the above discrimination signal is given to the gate circuit group 44, and as a result,
Read signals S2 and V2 are sent to gate circuit group 4 in this order.
4 are output in synchronization with the output of pulses P ₁ and P _{2 ,} respectively, and given to the subject register 6 and predicate/verb register 7 . Therefore, first, the translated word "toriha" is read out by combining the data "tori" written in the area 6B of the subject register 6 and the pre-stored data "ha" (data SD), and the translated word "toriha" is read out via the OR gate 45 and displayed in the buffer. 13. Next, the translated word "tobu" is read out from area 7B of predicate verb register 7 (data VD) and inputted to display buffer 13 via OR gate 45. As a result, the liquid crystal display section 16 displays the input translation of the English sentence "Toriha Tobu". FIG. 4 shows the storage states of the subject register 6 to complement register 10 after the search operation of the search circuit 5 is completed.

Next, a case of a sentence example of the fifth sentence type will be explained. Let's take an example sentence: She thinks the flower beautiful. Please note that when entering keys, use the article "the"
Also, "S" indicating the third person shall not be entered. In this case, operate the alphabet key, S key, V key, DO key, C key, and translation instruction key in the following order.

She, □S, think, □V, flower, 〓〓, beautiful,
□C, □translation. The word information "She", "think", "flower", and "beautiful" are sequentially input into the buffer 25 by the above key operations. Each time a key is operated, the signal is sent to the search circuit 5 and the search circuit 5 is caused to execute a search operation. Also, areas A, B of register 21,
Codes S, V, DO, and C are input to C and D, respectively, and stored. Furthermore, write signals S1, V1,
IO1 and C1 are output respectively, and the subject register 6,
It is given to the predicate verb register 7, indirect object register 8, and complement register 10. Then, in the search circuit 5, the word data "She", "think",
When each search operation for "flower" and "beautiful" is completed, the English word "She" and the translated word "kanojiyo" are stored in areas 6A and 6B of subject register 6, respectively, and areas 7A and 7B of predicate verb register 7 are stored. The English word "think" and the translated word "Omou" are respectively in the areas 8A and 8B of the indirect object register 8, and the English word "flower" and the translated word "hana" are respectively in the areas A and B of the complement register 10. The English word ``beautiful'' and the translated word ``utsukushii'' are respectively written in the . Furthermore, when a translation command signal is output by key operation of the translation command key, the code generation section 26 generates codes S, V, C, DO, and IO, which causes the outputs of the matching circuits 27, 29, 36, and 41. only becomes "1", and the sentence pattern discrimination circuit 3 outputs a discrimination signal indicating discrimination of the fifth sentence pattern. In the word order selection circuit 4, the gate circuit group 44 pulses the read signals S2, DO2, C2, and V2, respectively.
Output in synchronization with P ₁ , P ₂ , P ₃ , P ₄ , subject register 6, indirect object register 8, complement register 10,
are given to the predicate and verb registers 7, respectively. Therefore, the translated words "Kanojiyoha", "Hanawo", "Utsukushii", and "Omou" are read out from each register 6, 8, 10, and 7 in sequence and are provided to the display buffer 13. Therefore, the translated sentences "Kanojiyoha,""Hanawo,""Utsukushii," and "Omou" are displayed on the liquid crystal display section 16.

The operations when English sentences of the second, third, and fourth sentence types are input are the same as those for the first and fifth sentence types described above, so detailed explanation thereof will be omitted.

As explained above, according to this embodiment, there is no need for a mechanism to decipher the part of speech of an input English word, and it can be realized with a very simple configuration, resulting in low cost and high translation speed. be effective.

Note that by processing modifiers such as adjectives and adverbs as a pair of phrases with words such as nouns and verbs, it is possible to obtain translations of English sentences that include modifiers.

In addition, in the above embodiment, separate keys were provided for the direct object and indirect object, but only one object key was provided to determine whether the object was input only once or twice. The direct object and relative object may be determined by

As described above, according to the present invention, it is possible to translate an English sentence into a Japanese sentence that follows the correct word order, and it is possible to provide an extremely practical translation machine.
