Description

[Detailed description of the invention]

The present invention relates to an electronic translator that performs translation between different languages, and particularly relates to an electronic translator that stores languages.
Concerning ROM made up of plug-in modules. BACKGROUND ART Conventionally, electronic translators have been commercialized that use a plug-in module type ROM that stores a single language and perform translation operations between the language ROMs. In such conventional electronic translators, for example, if one of the plug-in modules is not set and translation is virtually impossible, when the device is activated and the translation operation is instructed, "Not Applicable" is displayed. There were cases where the following was displayed. However, in this case, the operator feels as if the translation is possible if another word is input, and the operation is extremely incomplete. The present invention completely eliminates the above-mentioned imperfections, such as forgetting to install a plug-in module or installing the wrong plug-in module (for example, those in different fields).
The object of the present invention is to provide a device that can be used extremely efficiently as a translator by disabling the translation operation when the translation operation is performed. Embodiments of the present invention will be described in detail below with reference to the drawings. Fig. 1 is a plan view showing the display section and key operation section of the electronic translator, Fig. 2 is a block diagram showing the system configuration, and Fig. 3a is a 1-chip micrometer used in this electronic translator.

Connected to the KEY strobe signal and KEY input signal line. The language ROM, , is a ROM that stores sentences and words for an electronic translator, and two ROMs correspond to one language.
These language ROMs are connected to the 1-chip microcomputer by the address bus and data bus, and the required language is selected by the chip select signals of CE ₁ , CE ₂ , and CE ₃ , and sentences or words are written. Can be read. CE ₄ is
This is the chip select signal for DISPLAY CONTROL & DRIVER. In this embodiment, the language ROM is built into the set, and the language ROM is a module that can be replaced as desired. Furthermore, in this embodiment, English, which is the most commonly spoken language, is selected as the language ROM. FIG. 3a is a block diagram showing the internal configuration of the 1-chip microcomputer shown in FIG. 2. In the same figure, the instruction ROM 3 stores instructions (instructions) for controlling each function of the electronic translator, and by sequentially increasing the addresses of the ROM 3, an instruction signal is generated, which is then When given to the CPU 4, the CPU 4 decodes the instruction signal (usually encoded) and executes the process. The data RAM 5 serves as a temporary storage of data necessary for executing each function of the electronic translator or as a conditional flip-flop necessary for branching in software. By accessing the address of the RAM 5, the CPU 4
It is possible to write to a desired address location in the RAM 5 or read content stored at a desired address location. S is KEY in Figure 2
This is a buffer for obtaining a strobe signal, and a key can be placed in a matrix position between its output line and the KEY input line, thereby allowing the key to be read. AD is an address register and is coupled to the address bus. This AD is used to set an address in the external memory, and is incremented, decremented, and set to a desired value via the CPU 4. The CPU 4 is also connected to an external data bus, and data is transferred to the external memory via this data bus.

FIG. 2 is an explanatory diagram showing the internal configuration of CONTROL & DRIVER. In this embodiment, a liquid crystal display (LCD) is used as a display, and the displayed characters are composed of 5×7 dots per digit, and 19 indicators are also displayed. DISPLAY CONTROL
& DRIVER consists of RAM 6, its address decoder 7, LCD back plate signal generator 8, and segment buffer 9.
Each bit of RAM 6 corresponds to each bit of the LCD display. When "1" is written to a certain bit in RAM 6, the corresponding dot on the LCD lights up. In FIG. 3b, S ₁ , S ₂ and S ₃ are segment signals for indicators, and S ₄ to _{S N} are segment signals for characters. M ₁ to _{M 7} correspond to the “▲” symbol (native language indication) in Figure 1, and F ₁ to _{F 7} correspond to the “〓” symbol (other language indication).
The numbers 1, 2 to 7 of M and F correspond to the languages English, German, . . . (see FIG. 1).
MT is polysemous, KA is kana, SN is sentence, WD is word,
* corresponds to the * indicator as is. The 1chip microcomputer writes data to this RAM 6 according to the content to be displayed. The language format shown in FIG. 4 is broadly divided into a control data area A, a compression table area B, a text area C, and a word area D. Words are not written exactly as they are spelled,
It is compressed and stored in the language ROM. Sentences are also made up of compressed groups of words. Compression tables are used to restore compressed words or to compress input spelling. The compression table differs depending on each language, and is configured to provide the highest compression rate for each language. The sentences are arranged into categories (airplane, Kankou, hotel, Kaiwa, etc.), and 1
There are several more sentences in one category. Words are similarly arranged and classified into categories. In addition, words are divided into 256 words, and the addresses of the first words of these 256 words (N ₀ , N ₁ , N ₂ , ... in Figure 4) are separately provided as a word start address table. There is.
This table is used to shorten the processing time when finding a word corresponding to a certain number.
(Details below). In the system configuration shown in FIG. 2, there are three types of language ROM, so mutual translation between the three languages is possible.
As shown in Figure 4, one language ROM stores sentences and words, and these are stored in each language ROM,...
There is a 1:1 correspondence between them. These correspondences are made using sentence numbers and word numbers that are common to each language ROM. For example English language
The 100th sentence in the ROM is “GODD
MORNING.'', then the Japanese language
The 100th sentence in the ROM is "Ohayo."
and in German it is ``GUTEN''
MORGEN.” This is also the case with words, in English
If the 500th word in the ROM is "SEE", the 500th word in the Japanese language ROM is
It is ``mil'', and its German equivalent is ``SEHEN''. (The following explanation assumes English language ROM,
Let the Japanese language ROM be and let the German language ROM be. ) To specify each language, press the "Language" key (1st
(see figure), and three combinations of desired languages from three countries are sequentially designated by pressing the key. Further, the native language and the foreign language are stored in a register as 4-bit values associated with each other based on the combination thereof, and the ROM designation of the module is performed according to the value of this register. The language code in control data area A in Figure 4 is 1 byte data, and the upper 4 BIT
indicates the language ROM field, and the lower 4 BITs indicate the language name. Here, the fields are fields targeted by the electronic translator, such as economics, engineering, and medicine. In this embodiment, the language names are as follows. Lower 4 BIT codes 0001 English 0010 German 0011 Japanese 0100 French 0101 Spanish Codes of 6 or higher are sequentially assigned to languages other than the above. FIG. 5 shows details of the word area D in FIG. 4. In word area D, data is arranged in units of 1 byte. The 8th BIT of the first character of one word is "1", and the 8th BIT of the character that is not the first character of a word is "0".
1BIT to 7BIT represent the type of character, including compressed codes. What is compression?
For example, when looking at WATCH, there is a 2 called WA
Characters are stored in 1 byte, 2 characters CH are compressed into 1 byte, and WATCH (5 characters) is compressed into 3 bytes and stored in the word area. In this case, 1-byte data corresponding to WA and CH becomes the compressed code. As mentioned above, words are mapped 1:1 between languages based on one meaning concept, but annotations are added to homographs to distinguish them from each other. In the example shown in Figure 5,
For WATCH, CLOCK (clock?) and SEE
(See?) There are two semantic concepts to distinguish between them: WATCH (CLOCK) and WATCH.
Annotations are indicated in parentheses, such as (SEE). These annotations are placed in the word area D following the annotation code (7E: hexadecimal display). An annotation may be placed after a word, or it may be placed before a word, and in this case, the annotation is placed following the annotation code (7D: hexadecimal representation). In other words, the comment for LOVE is (THE)LOVE
It is indicated by. Some words are compound words, which have a one-to-one correspondence with other languages based on a single semantic concept. In the example shown in FIG. 5, an example of a compound word HOT DOG is shown. Compound words are formed by inserting a space code (7B: hexadecimal representation) between words. Here, if one word is stored in the language ROM and at the same time becomes the first word of a compound word, the compound word code (7C: hexadecimal display) is written after the letter of that word. Attach.
In the example of Figure 5, the word HOT corresponds to this. HOT is an independent word in itself, and is also the first word of the compound word HOT DOG, so a compound word code is added after the word HOT. This is to show that when we find the word HOT, there is a compound word that starts with this word. As mentioned above, words are classified and arranged into several categories, and category classification codes (7F: hexadecimal representation) are used to indicate the divisions between categories. This code is placed at the end of the last word in the category. Fifth
The example in the figure shows that the word HOT DOG is the last word in a certain category. A code (FF: hexadecimal display) indicating the end of the word area is attached to the end of the word area. Next, the specifications of the electronic translator will be explained using FIGS. 1 to 5 described above. (1) Display In the character display section 1a in Figure 1, alphabets, katakana, numbers, and symbols are displayed, and in the indicator display section 1b, the symbol "▲" indicating the native language and the symbol "〓" indicating the foreign language are displayed. English,
It is displayed in correspondence with German, Japanese, French, Spanish, and the sixth and seventh languages. An indicator that lights up when a polysemous word is translated (polysemous word), an indicator that lights up when katakana input is possible (kana),
There is an indicator (sentence or word) that specifies when calling out a sentence or word, and an ``*'' symbol that lights up when there is a grammatically incorrect case when translated. (These displays are displayed on the DISPLAY shown in Figure 2.
It can be displayed by writing display data to CONTROL & DRIVER by a 1-chip microcomputer. ) (2) Translation function Translation by the electronic translator according to the present invention involves first finding out what number a sentence or word is specified in the native language ROM, then translating it in the foreign language ROM, Perform an action to pull out the sentence or word corresponding to that number. This translation function will be broken down and shown in the next step. First step - Select your native language ROM. Second step - find out what number the sentence or word is numbered in the selected language ROM. Third step - Select the language ROM to another language. Fourth step - From the number found in the second step, derive the sentence or word corresponding to this number in the selected language ROM. (3) Word translation function When you enter the spelling of a word using the character keys (Katakana, Alphabet) shown in Figure 1 and press the "Translate" key, it will translate from your native language to other languages indicated by the indicators (▲, 〓). Perform translation into Japanese. In this case, there are the following cases regarding the input spelled word. There is only one word in the language ROM selected as your native language that matches the spelling you entered.
If there is one. If there are multiple words in the language ROM selected as your native language that match the spelling you entered. (If the same word has multiple meanings, the same word will be stored in different word number positions corresponding to the number of meanings.) There is no word corresponding to the input spelling in the language ROM selected as the native language. case. Each case will be explained. ) means that the input word is the only one in the native language ROM.
Find the word number in the native language ROM, then select the foreign language ROM and retrieve and display the word corresponding to this number. For example, if the semantic concept of the 500th word in each language ROM,, is ``see'', then the English language
The 500th word in the ROM is "SEE" and the 500th word in the Japanese language ROM is "mil". Select the English language ROM as your native language, enter "SEE" and press the "Translate" key. First, the words will be pulled out from the word area D of the language ROM in Figure 4 and matched with the input spelling. Take. If there is no match, a counter that stores the word number is incremented, and the next word is moved on to find a match. In this way, when the word "SEE" is found and a match is established with the input spelling, the word number at that time is 500. Next, the CPU uses Japanese language ROM as another language.
, and pull out the 500th word in word area D in the ROM. Naturally, this word is "mil". In other words, if you key in "SEE" and then press the "translate" key, "mil" will be displayed and the word will be translated. ) are cases of homographs (i.e., the same word with multiple meanings has as many different word numbers as the number of meanings), and these words have annotation codes shown in Figure 5. It's attached. It is up to the person using the electronic translator to decide which meaning to use; first, the word is spelled in the same way but has a different meaning, and an annotation is added after the word is spelled. and! ? Mark. Taking WATCH in Figure 5 as an example, first
If you key in WATCH and press the "translate" key, WATCH (CLOCK)! ? is displayed. If you press the "Search" key here, other words with homographs will be shown, WATCH (SEE)! ? Display. WATCH (CLOCK)! ? or WATCH(SEE)! ? is displayed, then click "Translate"
When you press the key, the annotated translation will be displayed in the same way as above). When a word with such an annotation is translated, the polysemous word indicator shown in FIG. 1 lights up. This indicator is used to indicate that the translated input word has other meanings. ) is when the input word is not in the language ROM, and to indicate this, after the input spelling! ! Mark. for example,
The word ABALONE is not in the ROM, so if you enter this word and press the "Translate" key, ABALONE! ! is displayed. Next, an example of key operations for word translation is shown. When you enter the spelling of a word and press the "Translate" key, the input word is translated from your native language to the other language annotated to it. If you press the "Translate" key repeatedly, the original native language will be displayed, and then the native language and the other language will be displayed alternately in reverse.

【table】

【table】 ! ! NOT FOUND
It shows. TREES by "Search" key
Words close to TREE! ? Display with a mark added. This display indicates that you are asking if the word you are looking for is TREE.

【table】

[Table] The indicator lights up.
LOVE has two parts, a noun and a verb.
(THE)! ? indicates that you are asking whether it is the noun LOVE. Press the "Search" key
LOVE(TO)! ? and asks if it is the verb LOVE.

[Table] The word ABC is NOT FOUND, but this shows that it is treated like a proper noun (HOLD processing). in this case,
ABC becomes an untranslated word. (4) Translation function for multiple words You can key in two or more words and translate them as a series of words. When entering multiple words, use the "space" key. You can key in the spelling, press the "space" key, and if that word is in your native language ROM, you can key in the next word. If the key-input word is not in the native language ROM or is a homograph, the same operation as (ii) or (iii) of (3) above will occur. For example, the words I, AM, A, BOY are language
Assuming it is in the ROM, "I""Space""A""M""Space"
When you enter the keys ``A,''``Space,''``B,''``O,'' and ``Y,'' I AM A BOY is displayed. If you press the ``Translate'' key here, if the other language is Japanese, the message ``Watashiha Des Hitotsu no Shiyounen'' will be displayed. In this way, when translating multiple words, a word-to-word translation is performed regardless of word order or grammar. Therefore, if we consider these as one sentence,
Even if an input sentence is grammatically correct, when translated, the sentence is usually incorrect. To indicate this, the indicator in Figure 1 lights up when the above translation is performed. Next, an example of key operations when translating a plurality of words will be shown. By using the "space" key, you can line up multiple words and perform word-to-word translation.
When you press the "space" key, the display remains as the input word, but a translation operation is performed inside the device.

【table】

[Table] In the above word-to-word translations, there are cases where inflections, word order, etc. are grammatically incorrect, so the * symbol is lit after all translations. (5) Sentence translation function As shown in the language format diagram in Figure 4, the language ROM has an area C that stores sentences.
These memorized sentences are classified and arranged by category. The classification by category is related to the way the text is called. That is, the keys L ₁ , L ₂ , . . . , L ₁₄ arranged in an L shape in FIG. 1 make it possible to specify category classification. These keys function to call up a sentence when the "sentence/word" key is pressed and the indicator indicating the sentence lights up. For example, “sentence/
When the user presses the "Word" key to specify a sentence and then presses the key corresponding to _L3 ("Le"), the first sentence of the third category is called up from the language ROM. Each category contains several sentences, and when you press the ``search'' key, these sentences are called up in sequence, and when you reach the end of the category, you return to the first sentence in the same category. Thus, in the example of Figure 1, the text is 14
classified into categories. When calling up a sentence, find out the sentence number at the same time and press the "translation" key, the sentence will be translated from the third step of translation shown in section (2). The function of translating sentences by calling categories is broken down into the following steps. First step - Select the native language of the language ROM. Second step - press the "Sentence/Word" key to light up the sentence indicator. Third step - press the category key (any one from L <sub>1</sub> to L <sub>14</sub> ). Fourth step--Sequentially call up sentences using the "Search" key. (The text number is found in this step.)
At this point, press the "Translate" key to proceed to the next step. Fifth step - Select the language ROM to another language. Sixth step - In the selected language ROM, from the number found in the fourth step, extract the sentence corresponding to this number. (6) ( ) Translation function for sentences with parentheses Some sentences stored in the language ROM can be translated by changing the words or phrases in them. These variable parts are indicated by the display of parentheses ( ) when calling the text. Suppose that the following example sentence is called using the method described in (5). A LITTLE MORE (MILK) PLEASE.
If you press the ``Translate'' key without changing anything in parentheses, if the other language is Japanese, ``(milk) wo mouse con tadasai'' will be displayed. In the English sentence above, if you enter "C", "O", "F", "F", "E", and "E" before pressing the "Translate" key, the display will be A LITTLE MORE (COFFEE) PLEASE.
Then, if you press the "Translate" key, it will say (coffee). is displayed. However, this is the case when the word COFFEE is stored in the English ROM,
The rest of the process is the same as in (3)) and ). Translation when the content in parentheses above is changed is performed in the following steps. ( ) Calling up the example sentence is shown in the first to fourth steps of (5), so it can be described from the fifth step.Fifth step - Key in the desired word, then press the translation key. Step 6 - Selected native language
Find a word with the same spelling as the input word and its number in the ROM. If there is no word equivalent to the spelling entered here, or if there are multiple equivalent words, (3)
), ), but if the equivalent is a single word, proceed to the next step. Seventh step - Select the language ROM of another language. 8th step - Pull out the sentence corresponding to the already memorized sentence number from the selected foreign language ROM and put it in the buffer register. At this time, the ( ) code is also placed in the buffer register. 9th step - The word corresponding to the word number found in the 6th step is extracted from the selected foreign language ROM and entered in the buffer register in the 8th step. put the word inside. Next, we will show the case of a sentence with two parentheses. For example, I WANT(2)TICKETS TO (TOKYO). When you call the example sentence, the previous ( ) is doubled ( )
If there is no operation of the ( ) key, which will be described later, key input can only be made within the double ( ).
If you press the ( ) key here, the double ( ) display will move from the front to the back, allowing you to input into the following ( ). The translation procedure after lead-in is the same as the above steps. (7) Non-translation function For things that cannot be translated, such as people's names or proper nouns, you can hold the character with the "HLD" key and press the "Translate" key to return to the original without going through the translation steps. Display the characters as they are. Also, if you enter a spelling that is not generally stored in the language ROM, such as a person's name or proper noun, and then press the "Translate" key, you can do it once as mentioned in (3)! ! It will be displayed with a mark, but in this state click "Translate" again.
When the key is pressed, the original character is displayed as is. This non-translation function is effectively used for inserting words into parentheses, translating multiple words, etc. (8) AUTO HOLD function 0~9, $, ・, :,? If there are no other characters in a continuous word, numbers and symbols such as , etc. will be automatically untranslated without pressing the "HLD" key. (9) Recalling category words As shown in Figure 4, words are stored classified into several categories, and these words can be recalled by category in the same way as sentences. (10) Word spelling search You can randomly search for words with a spelling similar to the input spelling (Example 2 in (3),
(See 3). Next, with reference to FIGS. 6 to 13, a description will be given of means for controlling the invalidation of the translation operation for the language ROM that cannot be translated. Here, Fig. 6 is an explanatory diagram of the memory, Figs. 7, 8, 9, 10, and 11 are flowcharts, Fig. 12 is an explanatory diagram of the native language and foreign language corresponding to the value of register K, and Fig. 13 Figure a is an explanatory diagram showing an example of the indicator display corresponding to the operation of the "Language" key and the "▲〓" key, and Figure 13 b is an explanatory diagram showing the change in the language specification due to the operation of the "Language" key and the "▲〓" key. FIG. FIG. 6 shows the register K indicating the combination of the native language and foreign language, and the module language code (see FIG. 4) input buffers MD ₁ and MD ₂ . The register K has 4 bits (K ₁ to _{K 4} ) and has six values depending on the combination of the native language and foreign language, as shown in FIG. 12. MD ₁ is the input buffer for the language code of language module 1, and the upper 4 bits are
MD ₁ (H), lower 4 bits are shown as MD ₁ (L). MD ₂
is the language code input buffer for language module 2, the upper 4 bits are MD ₂ (H), and the lower 4 bits are
Denoted by MD ₂ (L). The above register K and input buffers MD ₁ and MD ₂ are the RAM shown in Figure 3a.
installed in a predetermined area within the FIG. 7 shows a flowchart showing the process from the time the battery is replaced. The following shows the initial setting of the value of register K at the time of battery replacement. If the electronic translator of the present invention is equipped with a battery, the settings in the language ROM will be stored in memory even when the power switch is turned off. There is no need to make new language ROM settings when turning on. This will be explained below using FIG. 7. In the same figure, auto clear operation ACL at n ₁
is performed, and the _module (language ROM
) is read into MD ₁ , and the language code in the module (language ROM) is read in n ₃ .
Loaded into MD ₂ . A flowchart for reading such a language code is shown in FIG. According to the same figure, the module (language
When reading the language code in ROM), clear all of the chip select signals CFi with _m1 , and then press _m2.
Set only the chip select signal _CE2 to specify only the module, and set the address “0045” where the language code in the module is stored at _m3.
(displayed in hexadecimal). Next, at _m4 , the data (language code) stored at the address "0045" is taken into the accumulator. Next, in _m5 , the language code taken into the accumulator is stored in _MD1 . Also when reading the language code in the module (language ROM) m ₁ ′ ~
The same is done for m ₅ ′. In this way, the processing of n ₂ and n ₃ in FIG. 7 is performed. At n ₄ and n ₅ , it is determined whether the contents of the buffers MD ₁ and MD ₂ are FF (hexadecimal representation). Here, if the module or MD is not inserted, the code "FF" is read into the buffer MD ₁ or MD ₂ . This is because the data bus is connected to the "H" potential by a resistor. If neither the module nor the module is inserted, proceed to n ₅ →. What this shows is explained in Figure 8,
This causes an error to be displayed. In other words, in this method, an error is displayed when both modules are not inserted. If only the next module is inserted, proceed to n ₅ → n ₆ . At n ₆ , it is determined whether MD ₂ (H) is 0 or not. As already mentioned, the language code stored in the language ROM is 1-byte data, with the upper 4 bits indicating the field of the language ROM (economics, engineering, medicine, etc.) and the lower 4 bits indicating the language name. Here are the top 4
If the bit is 0, it indicates that it can be used in correspondence with the built-in ROM. That is, the judgment of _n6 examines the possibility of mutual translation processing between the module and the built-in ROM. If YES at _n6 , "2" is input to register K at _n7 (see FIG. 12). i.e. internal ROM (here in English)
Set the module as the native language and the module as the foreign language. Next, flag FM is set at _n8 . The flag FM indicates that one module cannot be used, and in the above n ₄ , MD ₁ is
This is because it was FF (no module was inserted). Moving to n ₈ →, the corresponding language designation indicator is displayed. Above n ₆
If MD ₂ (H) is not 0, proceed to step and an error is displayed. In the judgment of n ₄ above, if MD ₁ is not FF, that is, if a module is inserted, n ₉
Move to. At _n9 , it is determined whether MD ₁ (H) is 0 (same as _n6 ). If Yes at _n9 , that is, if the module and built-in ROM can be translated into each other, 0 is sent to the register K at _n10 (12th
(see figure). Next, at _n11 , it is determined whether MD ₂ (H) is 0 or not (same as _n6 ). In this n ₁₁
If No, proceed to _n12 , set the flag FM, and display the corresponding language designation indicator. If _n11 is Yes, the flag FM is not set, and the corresponding language indicator is displayed at n11.
Next, if MD ₁ (H) is not 0 at n ₉ , that is, if the module does not correspond to the built-in ROM, compare MD ₂ (H) and MD ₁ (H) at n ₁₃ . Let's do it. That is, it is determined whether the fields of the modules are the same. ₁₃
If MD ₂ (H) and MD ₁ (H) are different in , move to n ₆ . At n ₆ , judge whether the above MD ₂ (H) = 0 or not.
If No, both the module and the module cannot be translated with the built-in ROM, and it is also impossible to translate between the modules, so an error message will be displayed. If MD ₂ (H) and MD ₁ (H) match at n ₁₃ , the modules store a common field different from the built-in ROM. At this time, 4 is sent to register K at _n14 (see Figure 12). after that
Flag FM is set at _n15 , and display is performed using a predetermined language designation indicator. By following the above procedure, a value corresponding to the inserted module can be set in register K when replacing the battery. Next, the operation of specifying a language in the normal state will be explained using FIG. In _S1 , it is determined whether or not a key is pressed. In _S2 , it is determined whether to set or reset the flag FE indicating an error state. In _S3 , it is determined whether or not the "translation" key is pressed. In _S4 , it is determined whether or not the key "▲〓", which instructs conversion between the native language and the foreign language, is pressed. At _S5 , it is determined whether the "language" key is pressed or not.
Assume that you have now pressed the "Language" key. At _S6 , it is determined whether the flag FM indicating that one module cannot be used is set or reset. In S ₆
If Yes (FM set), the "Language" key becomes a non-operation and proceeds to S ₂₆ , so S ₇ → S ₈ → S ₉ ...
No judgment will be made. If No in S ₆ (FM reset), K = in S ₇
Determine whether it is 0 or not. As shown in FIG. 12, when K=0, English is the native language and the module (Japanese) is the foreign language. Now that the "Language" key has been pressed, in FIG. 13b, for example, the module (Japanese) is the native language, and the module (German) is the foreign language. According to FIG. 12, the value of register K should be 4. Therefore, if _S7 is Yes, 4 is put into register K in _S13 . This S ₇
Similarly to the case of S 13 and S ₁₃ , referring to the relationships in FIGS. 12 and 13 b, S ₈ and S ₁₄ , S ₉ and S ₁₅ , S ₁₀ and S ₁₆ , S ₁₁
The relationship between and S ₁₇ becomes clear. S ₇ →S ₈ →S ₉ →S ₁₀ →
If all of S ₁₁ are No, the value of K is 5, so S ₁₂
, put 1 in K. After the above operations, a symbol switching operation (described later) is performed in _S18 , and a symbol for a new language designation is displayed in _S19 . Further, the operation of reversing the designation of the native language and foreign language by pressing the "▲" key shown in FIG. 13B is performed as follows. 12th
As shown in the figure, when the native language and foreign language are reversed, only the one-digit value (K ₁ ) of register K is reversed. Therefore, if it is determined in S ₄ that the "▲〓" key is pressed, it is determined in S ₂₆ whether K ₁ = 1 or not, and the No.
If so, K ₁ is set to 1 in S ₂₇ , and if Yes, K ₁ is set to 0 in S ₂₈ . Thereafter, the symbol is switched in _S18 , and the switched symbol is displayed in _S19 . The value of K is determined in the manner described above. Here, FIG. 13a shows an example of the indicator display corresponding to the operation of the "language" key and the "▲=" key. As shown in Figure 7, if translation is impossible, the process moves to step 8, but if the process proceeds as shown in Figure 8, the flag FE is set in _S21 , and the error message is sent to the input buffer IB in _S22 . An error message is displayed in _S19 . In _S2 , a determination is made whether to set or reset the flag FE. If Yes, press the "C/ON" key in _S23 , reset the flag FE in _S24 , and clear the flag in _S25 . If the "C/ON" key is not pressed in _S23 , the process returns to _S1 . After setting the desired language through the above operations, press the "Translate" key and the result will be Yes in _S3 .
At _S20 , the language ROM is set according to the contents of register K above.
Select , load the data, and perform the translation process. Next, the operation of displaying an indicator corresponding to the value of the resist K will be explained using the flowcharts of FIGS. 9 and 10. Now, by the operation shown in Figs. 7 and 8, K
It is assumed that the value of has been determined. Figure 9, 1st
In Fig. 0, M ₁ , M ₂ , ..., M ₆ are memories corresponding to the symbol "▲" indicating the native language in the ROM already shown in Fig. 3 b,
F ₁ , F ₂ , . . . , F ₆ are memories corresponding to the symbol “〓” indicating a foreign language. If register K is 0, M ₁ is set to 1 and SUB F
Move to. If register K is 1, set F ₁ to 1 and move to SUB M. If register K is 2
Set M ₁ to 1 and move to SUB F. Register K is 3
If so, set F ₁ to 1 and move to SUB M. If register K is 4, move to SUB M, then SUB
Move to F. If register K is not 0-4, it is 5, so the process moves from SUB M to SUB F. The above operation is based on _the value of register _K.
and a predetermined one among F ₁ to F ₆ is set. When this process is performed, the symbols "▲" and "ⓓ" specifying the desired language are lit. The subroutines SUB F, SUB M, shown in Figure 9
SUB M is shown in FIG. To explain SUB F, after resetting Fi, a judgment is made regarding the content to be stored in MD ₁ (L). The language name is stored in the MD ₁ (L).
Therefore, depending on the content stored in MD ₁ (L), each F ₁ ~
Set F ₇ . To explain SUB M, after resetting Mi, a judgment is made regarding the contents stored in MD ₁ (L), and each of M ₁ to _{M 7} is set. SUB F,
In SUB M, the same process as above is performed as MD ₂ (L)
This is what we do about this. As explained in detail above, according to the electronic translator of the present invention, it is possible to confirm the installation of a language ROM that stores a language, and when the language ROM is confirmed, it is unclear whether translation is possible using the installed language ROM. By determining whether the translation operation is possible, it is possible to disable the translation operation, so it is possible to check in advance if a language ROM has been forgotten to be installed or if the wrong language ROM has been installed, and the operator can immediately detect the defective state. As a result, the equipment can be used efficiently.
