Description

[Detailed description of the invention] The present invention relates to an electronic translator.

In recent years, electronic translators have been developed that, when a Japanese word is input, the translated word is translated into English and displayed.

However, because this type of translator needs to store as many words as possible in its memory, which has limited capacity, it is necessary to store as many words as possible in its memory, which has limited capacity. is not stored in memory.

Therefore, the above-mentioned words can only be translated in their original form, and the user has to convert the word he or she wishes to translate into its original form before inputting it into the translator.

This invention was developed in view of the above circumstances, and for words that have regular inflections, it is possible to translate the inflections without storing the inflections in memory, and it also speeds up the search. The purpose is to provide an improved electronic translator.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a plan view of an electronic translator employing the present invention.

A group of various keys 2 are arranged on the top surface of the main body 1 of the translator, 3 is a power on and all clear key, 4 is a power off key, 5 is a key for instructing Japanese input mode, and 6 is a key for instructing English input mode. 7 is a key for instructing translation of an input word or sentence, 8 is a single character correction key, 9 is a lowercase letter designation key, and 10 is a space key.

On the other hand, the remaining keys are keys for inputting English or Japanese. After operating the above Japanese key 5, the kana written on each key is input manually, and after operating the English key 6, each key is input manually. The alphabet written in is input.

Further, numeral 11 denotes a display section, which is comprised of, for example, a 5.times.7 dot matrix liquid crystal display device with 20 digits.

Next, FIG. 2 shows the overall configuration of an electronic translator employing the present invention.

20 decodes the key operation signals of each group of keys and sends the key codes of alphabet keys, kana keys, etc. to the key buffer 21, and also controls key operations of control keys such as Japanese key 5, English key 6, translation key 7, etc. Sometimes it is a decoder that sends the key code to the control circuit 22.

This control circuit 22 controls the entire system and includes a micro-instrument system, a timing control circuit, and the like.

Further, a memory 22M is connected to the control circuit 22.

This memory 22M includes arithmetic registers, flag registers, and the like.

The key buffer 21 sequentially shifts and holds the input characters, and when a read signal is given from the control circuit 22 via the signal line a, the stored word information is passed through. Comparator circuit 2 via line b
Send to 3.

This comparison circuit 23 is connected to the first RO via a pass line C.
The data output from the M pattern 24 is supplied, and the data in the key buffer 21 and the fourth R pattern are
The data of the OM pattern 24 is compared, and the comparison result is output to the control circuit 22 via the pass line a, and the character portion that matches as a result of the comparison is sent to the control circuit 22 via the pass line d.

The first ROM pattern 24 has a storage structure as shown in FIG. 3, and stores the ending part of the inflection of a word and a status flag when the ending is used.

Note that the ending part of the word is memorized in reverse order.

On the other hand, 25 is a second ROM pattern, which consists of an English area, and as shown in FIG. 4, stores words, their part-of-speech information, and addresses where words to be translated are stored.

For example, the past tense of the word rsTOPJ is ``
It becomes 5TOPPEDJ, with the same letter P at the end of the original word P.
, and 1-EDJ is added after that.

In this way, words that overlap the ending of the base form when inflected are:
A special mark "△" and a character to be overlapped are added to the end of the original word.

The words stored in this second ROM pattern 25 are passed to the discrimination circuit 26 and to the comparison circuit 23 via the path line e.
and is compared with data sent from the control circuit 22 via path lines d and b.

Addressing of the first ROM pattern 24 and the second ROM pattern 25 is performed using address information obtained by decoding an addressing signal outputted from the control circuit 22 via the path line f by the ROM address decoder 2γ. It will be done.

The discrimination circuit 26 discriminates whether or not there is a special mark in the word read from the second ROM pattern 25, and sends the characters until the special mark is detected to the comparison circuit via the path line e. , a circuit that sends a special mark detection signal to the control circuit 22 via the signal line g, the details of which will be described later.

Further, 28 is an address buffer for storing a bilingual address stored together with the word in the second ROM pattern 25 that matches the input word as a result of the comparison process. The decoder 21 decodes the second ROM pattern 2.
Specify address 5.

29 is a display control circuit, and 30 is a display device, which displays input words and translated words.

Next, the configuration of the discrimination circuit 26 will be explained with reference to FIG.

The word data output from the second ROM pattern 25 is written into the buffer 52 via the AND gate 51, and sent to the comparison circuit 23 via the pass line e.

Further, the data from the second ROM pattern 25 is input to the decoder 53 and decoded, and the special mark "
” is detected, a “1” signal is output to the Nant gate 54.

On the other hand, 55 is an S-R type flip-flop, and the first RO
When matching data is obtained in the comparison process for the data of the M pattern 24, a reset signal R is applied from the control circuit 22 when the set signal S is not obtained.

The output signal of this flip-flop 550 when set is supplied to the Nant gate 54.

Therefore, this Nantes Gate 54 has a translation mode of English→
When a matching output is obtained during the comparison process for the first ROM pattern 24 in the Japanese mode, only when a special mark is detected in the word read from the second ROM pattern 25, the output becomes 0''. Become.

The output signal from the Nandt gate 54 is supplied to the AND gate 51 as a gate signal, and is also outputted to the control circuit 22 via the signal line g as a comparison processing stop request signal.

Next, the operation of this embodiment configured as described above will be explained.

First, taking the case of translating the word rsPEAKsJ as an example, first operate the English key 6 to set the English input mode.

At this time, the operation signal of the English key 6 is decoded by the key decoder 20, and the key code is sent to the control circuit 22, whereby the control circuit 22 is set to the English manual mode.

Next, when r5PEAKSJ is input using the alphabet keys, codes for each alphabet are created by the key decoder 20 and input into the key buffer 21.

Next, when the translation key 7 is operated, the operation signal is given to the control circuit 22, and the control circuit 22 gives a read command to the key buffer 21 via the pass line a, and also outputs a comparison command to the comparison circuit 23. At the same time, the comparison process is started by specifying the start address of the first ROM pattern 24 via the path line f.

At this time, the words stored in the key buffer 21 are compared with the contents of the first ROM pattern 24 starting from the end.

That is, rSPEAKSJ is compared in the order of rsKAEPsJ.

First, rDJ is read from the first ROM pattern 24 and inputted to the comparison circuit 23 together with the contents of the key buffer 21, and a comparison process is performed. control circuit 2
Send to 2.

As a result, the address of the first ROM pattern 24 is incremented and then compared with 1-DEJ.

Similarly, when rsJ is read from the first ROM pattern 24, a match of the last "S" of rSPEAKSJ is detected, and the comparison circuit 23 outputs a match signal to the control circuit 22 via the path line a. do.

The control circuit 22 receives this coincidence signal and applies a set signal S to the flip-flop 55 in the discrimination circuit 26 via the path line a.

Further, the flag information indicating the situation written together with the data "S" read from the first ROM pattern 24 is sent to the control circuit 22 via the comparison circuit 23 and the path line d, and is stored in the memo IJ22M. is written to the flag register configured in

Furthermore, the control circuit 22 deletes the matching characters from the words stored in the key buffer 21 and writes the remaining characters into the memory 22M.

As a result, rsPEAKj is stored in the memory 22M.

Next, the data stored in this memory 22M and the second R
Comparison processing of the data written in the OM pattern 25 is performed.

First, the control circuit 22 connects the second RO via the pass line f.
Specify the start address of M pattern 25.

The word at the designated address is read from the second ROM pattern 25 and supplied to the AND gate 51 and decoder 53 of the discrimination circuit 26 .

At this time, the translation mode is English→Japanese mode, and the flip-flop 55 is set.

Therefore, when the address of rsPEAKJ in the second ROM pattern 25 is designated, the read data is sent to the AND gate 51 and decoder 53 as "S", rPJ, "E0... However, since the special mark is not detected by the decoder 53, the output of the Nante gate 54 is "191", so the data output from the second ROM pattern 25 is directly passed through the AND gate 51. The data are sequentially written into the buffer 52.

Then, it is sent to the comparison circuit 23, and the above-mentioned memo IJ22
A comparison is made with the data written in M, and if a match is detected, rsPEAKJ of the second ROM pattern 25 is
The part of speech information and bilingual address stored together with the part of speech are read into the control circuit 22 via the discrimination circuit 26, comparison circuit 23, and pass line d, and it is determined that the part of speech is a verb.

Therefore, as the status flag of "S" read in the first ROM pattern 24, the information of "plural form" and "third person singular present tense" is held in the flag register in the memo 'J22M. However, since rsPEAKJ is a verb, it can be seen that it is "third person singular present tense",
The "plural" flag is cleared.

Further, after the bilingual address is written to the ROM address buffer 28, the second ROM pattern 25 is designated and the rs
Word memo ``Hanas'' which is the translation of PEAKJ lJ2
Read out to 2M.

The translated word "hanas" obtained by the above operation is sent to the display device 30 via the display control circuit 29 together with the flag information, and is displayed on the display section 11 in the format shown in FIG. 6a, for example.

Furthermore, when rcATcHEsJ is input, rEsj is retrieved from the first ROM pattern 24 and rCATCHJ is retrieved from the 20R, 0M pattern 25 by the same operation as described above, and the translated word "Tsukamaeru" is obtained.

Next, a case will be explained in which a word such as rsTOPPEDJ is input in which the ending of the original word is changed.

Regarding the search for the first ROM pattern 24, the same operation as above is performed, and a match of rEDJ is obtained.

At this time, rsTOPPJ is stored in the memory 22M.

In the comparison process for the second ROM pattern 25, rSTOPΔP is found in the second ROM pattern 25.
” words are memorized.

Then, up to "S" rTjrOJrPJ are written to the buffer 52 in the same manner as above, but when the special mark "△" is read out, the decoder 53 outputs the "'l" signal, and the output of the Nant gate 54 is 0'', and the special mark "△" is inhibited by the AND gate 51.

At the same time, it is applied to the control circuit 22 as a comparison operation stop request signal via the ``0''0'' signal line g of the output of the Nant gate 54.

Therefore, the control circuit 22 stops the comparison operation for one character.

Then, when the next character "P" following the special mark "△" is read from the second ROM pattern 25, the output of the decoder 53 becomes 0" again, and the output of the Nant gate 54 becomes +l lI+. AND gate 51 is opened.

Therefore, the character rPJ read from the second ROM pattern 25 is written into the buffer 52 via the AND gate 51.

Further, when the output of the Nant gate 54 becomes "1", the control circuit 22 gives a comparison command to the comparison circuit 23.

As a result, the comparison operation is restarted, and a match between the data rSTOPPJ stored in the memory lJ22M and rsTOPPJ read from the second ROM pattern 25 is detected.

By this coincidence detection, the rs of the second ROM pattern 25
The translation address of 'rop△P' is address buffer 28
By specifying the address where the corresponding translated word is stored in the second ROM pattern 25,
The translated word "Tomal" is read out and displayed on the display unit 11 as shown in FIG.

Although the above explanation did not explain the search operation when the word is input in its original form, the input word is first searched in the second ROM pattern 25 in its original form, and a matching word is found. If it is not found, it is sufficient to proceed to the above-mentioned word ending search process.

When searching for the second ROM pattern 2, the Nante gate 54011071 signal generated when the decoder 53 in the discrimination circuit 26 detects a special mark acts as a temporary stop request instead of a comparison process end request. , the comparison is made with the special marks removed.

In addition, in the above embodiment, flags indicating situations such as third person singular present tense, plural form, past tense, etc. are read out and the corresponding situation is displayed when displaying the translated word. Based on this flag information, the translated word is displayed. It may be possible to transform itself into a shape that suits the situation.

Furthermore, in the above embodiment, the processing when English is input is explained as an example, but when Japanese is input, the processing can be performed based on the same principle.

As described in detail above, according to the present invention, when searching for a word from the dictionary memory, a comparison is made from the character at the end of the word to detect a regular declension ending, and the basic word is obtained by removing the regular deformation ending part from the input word. Since the inflectional forms can be obtained, the translation can be performed without storing the inflectional forms in memory.

Also, by starting the comparison from the end of the input word,
Rule change endings can be detected easily and reliably, and translation processing speed can be improved.
