Examples of the display mode include changing the color of the headword, changing the typeface, changing the character font, adding an underline, or adding a box.

According to another aspect of the present invention, there is provided an electronic dictionary search method comprising a dictionary data storage unit for storing at least one dictionary data, an input step for inputting a search word, and the search word as first dictionary data. A first search step for performing a first search, a storage step for storing a search result of the first search step, and a second search for extracting a search term from the second dictionary data for the search result. And a display step for displaying the extracted headwords.
According to another aspect of the present invention, there is provided an electronic dictionary search program including a dictionary data storage unit for storing at least one dictionary data, an input step for inputting a search term, and the search term as a first dictionary data. A first search step for performing a search, a storage step for storing a search result of the first search step, and a second search step for extracting a headword that can be searched with second dictionary data for the search result; The electronic dictionary search program causes a computer to execute a display step of displaying the extracted headword.

  The electronic dictionary of the present invention extracts a search word by performing a first search with the first dictionary data and performing a second search for extracting a headword that can be searched with the second dictionary data for the search result. Thus, the headword displayed on the display means is only the headword that can be searched in the second dictionary, and the second search result can be obtained without fail. Thereby, the user does not feel inconvenience in the second search.

In the electronic dictionary of the present invention, the first dictionary data and the second dictionary data may be the same, so that, for example, a national language dictionary is used in the first search, and the search result is displayed and displayed. If there is a questionable entry word in the sentence of the search result, the second search can be further performed using the same national language dictionary, and the search result displayed by the first search can be fully understood. . Moreover, according to the present invention, searchable headwords in the sentence displayed in the first search result are displayed, so that the second search does not feel inconvenient. In addition, the first dictionary data and the second dictionary data may be different, so the dictionary can be widely used by using other dictionaries such as the technical dictionary, encyclopedia or Japanese-English dictionary next to the national language dictionary. You can select and search.
In the electronic dictionary of the present invention, the first dictionary data is a synonym dictionary and the second dictionary data is language dictionary data. Therefore, a synonym that can be searched with the second dictionary data for a search word input by the user. Data is searched, and searchable keywords are extracted from the language dictionary data for the search results. When a synonym is selected from the displayed keywords, the user can search the language dictionary data without searching. Can do.
Further, the electronic dictionary of the present invention extracts headwords that can be searched with the third dictionary data from the search result of the first search means, so that, for example, a search word is first searched in the synonym dictionary, and the synonym is searched. English-French dictionary data and Japanese-French dictionary data can be searched continuously for English and French.

The electronic dictionary of the present invention further includes a first storage unit that stores the headwords extracted in the second search, and a second storage unit that stores the headwords extracted in the third search. Therefore, by reading the first storage unit and the second storage unit, the second search result and the third search result can be switched or displayed simultaneously.
The electronic dictionary of the present invention is dictionary data in which at least one of the first dictionary data, the second dictionary data, and the third dictionary data is stored in a storage card that can be taken in and out of the electronic dictionary. The dictionary data other than the dictionary installed in can be used in the same manner as the dictionary data installed in the electronic dictionary by inserting the storage card.

  Further, the electronic dictionary of the present invention performs a first search for the search word using the first dictionary data, displays the search result, extracts a character string from the search result, and can search for the search word using the second dictionary data. Is extracted and displayed, so that the user can select the search word for the second search by looking at the search result displayed on the first display means. As a result, the second search can be performed for the headword that seems to be a question in the search result.

A block diagram of the electronic dictionary of the present invention is shown in FIG.
The electronic dictionary of the present invention comprises a control unit 1 comprising a CPU, a non-volatile memory such as a ROM and a hard disk, a storage unit 2 for storing various types of dictionary data and programs, and a temporary storage element such as a RAM. A first search result storage unit 3 that stores one search result, a second search candidate storage unit 4 that includes a temporary storage element such as a RAM and holds a headword that can be subjected to a second search, and input of characters and operations It comprises an input unit 5 for performing the above and a display unit 6 as an output device. The control unit 1 includes a search unit 7 and a comparison unit 8. This block diagram includes one second search candidate storage unit 4, but preferably two or more.

  In the present invention, the dictionary stored in the storage unit 2 is, for example, a national language dictionary 2a such as a national language dictionary, original language dictionary, kanji dictionary, idiom dictionary, dialect dictionary, synonym dictionary, Japanese-English dictionary, English-Japanese dictionary, English-English dictionary, English-language dictionary, English-language dictionary 2b such as English-language dictionary, German-language dictionary 2c, German-English dictionary, Japanese-German dictionary, French-language dictionary 2d, Japanese-English dictionary, French-Japanese dictionary Chinese dictionary 2e like dictionary, encyclopedia 2f, medical dictionary, medicine dictionary, health dictionary, health dictionary 2g like food dictionary, travel guide, ceremonial occasion dictionary, trivia dictionary, life like speech collection It includes a related dictionary 2h, an electrical term dictionary, a medical term dictionary, a chemical term dictionary, a technical term dictionary 2i such as a semiconductor term dictionary, an insect picture book, a plant picture book, a modern term dictionary, and many other types of dictionaries 2j. Since many electronic dictionaries are portable, the number of dictionaries that can be stored in the storage unit 2 is limited. However, the greater the number of dictionaries of the present invention, the wider the range of use and the more convenient it can be used.

The control unit 1 according to the present invention executes an input process and an output process by executing a program stored in the storage unit 2. The control unit 1 also includes a search unit 7 that searches various dictionary data in the storage unit 2 and a comparison unit 8 that compares the first search result and the second search result. Further, the first search result by the search unit 7 is stored in the first search result storage unit 3 and the result of the comparison unit 8 is controlled to be stored in the second search candidate storage unit 4.
The input unit 5 includes an input device such as a keyboard, a pointer, a mouse, and a touch panel, and performs operation inputs such as character input and search. The display unit 6 uses a liquid crystal display device, displays an input screen for prompting input of a search word, and displays a headword as a search result.
The electronic dictionary of the present invention is configured as described above, and when the user inputs a desired search word, the first search is performed using the first dictionary, and the search result is stored in the first search result storage unit 3. To do. Then, a second search is performed on the stored search results using the second dictionary. By this second search, a headword capable of the second search is extracted from the first search result using the second dictionary, and the extracted headword is stored in the second search candidate storage unit 4. It is stored and displayed as a search candidate on the display unit 6.

Next, the operation of the electronic dictionary of the present invention will be described using the flowchart of FIG.
First, the user inputs a desired search word from the input unit 5 (S1), and selects a first dictionary to be used when searching for this search word (S2).
Next, when the user instructs search execution from the input unit 5, the search unit 7 of the electronic dictionary performs a first search using the first dictionary (S3). Next, in step S4, the search result obtained by the first search is stored in the first search result storage unit 3. Next, in step S5, the user selects a second dictionary to be used for the second search. Accordingly, the electronic dictionary search unit 7 uses the second dictionary to perform the second search (S6). With this second search, the comparison unit 8 determines whether one of the search result headwords stored in the first search result storage unit 3 exists in the second dictionary (S7). Headwords existing in the second dictionary are stored in the second search candidate storage unit 4 (S8), and headwords not existing in the second dictionary are deleted. Next, in step S9, it is determined whether or not the second search has been performed for all the headwords obtained in the first search result. If there are still headwords in the first search result, the process returns to step S6. Repeat cycle. When the second search has been performed for all the headwords obtained from the first search result, the process proceeds to step S10, and the headwords stored in the second search candidate storage unit 4 are displayed on the display unit 6.
The user selects a desired headword from the search result displayed on the display unit 6 and searches the second dictionary. In the case of this second search, according to the present invention, a search result can always be obtained.

As described above, according to the present invention, only the headwords that can be searched in the second dictionary for the first search result are extracted and displayed on the display unit. Therefore, the search result can be obtained from the second dictionary for all headwords designated by the user.
In this flowchart, the selection of the second dictionary is performed after obtaining the first search result. However, the input of the search word, the selection of the first dictionary, and the selection of the second dictionary are continued after the start. You may go. Alternatively, the user may set the first dictionary and the second dictionary as initial settings of the electronic dictionary. Furthermore, it may be set by the manufacturer and seller of the electronic dictionary.
In addition, after the second search, a means for selecting a dictionary to be used for the third search, and a third word for extracting a headword that can be searched in the third dictionary from the search result of the first search means If a search means is further provided, for example, the search word can be searched first in the synonym dictionary, and the synonym can be continuously searched in the Japanese-English dictionary and the Japanese-French dictionary. Further, a first storage unit that stores headwords extracted as searchable in the second dictionary and a second storage unit that stores headwords extracted as searchable in the third dictionary are further provided. By reading out the first storage unit and the second storage unit, the second search result and the third search result can be displayed simultaneously or in a switched manner. Also, the electronic dictionary of the present invention is mounted on the electronic dictionary when at least one of the first dictionary, the second dictionary, and the third dictionary is a dictionary stored in a storage card that can be taken in and out of the electronic dictionary. A dictionary other than the dictionary can be used in the same manner as a dictionary installed in an electronic dictionary by adding a storage card by inserting a storage card. In addition, the present invention displays the headwords determined to be searchable in the second dictionary by the second search without displaying the first search result, so that the user is not confused.

(Embodiment 1)
In the first embodiment, a search word is input, a synonym for the search word is subjected to a first search using a synonym dictionary, and then converted into English or Japanese using a Japanese-English dictionary or an English-Japanese dictionary in a second search. Will be described.
FIG. 3 shows a block diagram of an electronic dictionary according to the first embodiment, and includes a control unit 11, a storage unit 12 that stores dictionary data and a program, a storage unit 13 that constitutes a synonym pattern candidate holding unit, and a search candidate index holding unit. Storage unit 14, an input unit 15 for inputting characters and operations, and a display unit 16 as an output device. The control unit 11 includes a search unit 17 and a comparison unit 18. The dictionary data stored in the storage unit 12 includes, for example, Japanese synonym dictionary data stored in the storage unit 12a, English synonym dictionary data stored in the storage unit 12b, and Japanese language dictionary data stored in the storage unit 12c. English-Japanese dictionary data is stored in 12d, Japanese-English dictionary data is stored in the storage unit 12e, Japanese-French dictionary data is stored in the storage unit 12f, and French-Japanese dictionary data is stored in the storage unit 12g. Note that it is desirable to provide two or more storage units 14.

Next, the operation of the electronic dictionary of Embodiment 1 will be described using the flowchart of FIG. Here, it is assumed that “search” is input.
First, the user inputs a desired search term from the input unit 15 (S11). If the input search word is a hiragana reading, the electronic dictionary search unit 17 selects a Japanese-language synonym dictionary and performs a search (S12). That is, the Japanese synonym dictionary data stored in the storage unit 12a of the storage unit 12 is used. Alternatively, when the input search word is a spelling, English synonym dictionary data stored in the storage unit 12b is used. In step S13, the synonym dictionary is searched to determine whether a search result exists. If there is no synonym for the search term, for example, “not found” is displayed on the display unit 16 and the search is terminated. If there is a synonym for the search term, the synonym is listed (S14). For example, the result of searching for a new synonym dictionary is as shown in Table a in FIG. As shown in Table a, “Examination, exploration, inspection, washing, investigation, exploration, reexamination, censorship, inspection, inspection, ticket gate, inspection, reconnaissance, examination, inspection, inspection, exploration, examination, open bid, inspection” are obtained. It is done. This search result is held in the storage unit 13 constituting the synonym pattern candidate holding unit. This search result is not displayed on the display unit 16.

  Next, the electronic dictionary determines a second dictionary to be used for the second search (S15). The translation dictionary installed in the electronic dictionary includes a Japanese-English dictionary, an English-Japanese dictionary, a Japanese-French dictionary, and a French-Japanese dictionary. As a method for determining the second dictionary, there is a method in which a second dictionary used for the second search is set in advance in the electronic dictionary, or a method in which the user selects from a dictionary installed in the electronic dictionary. . When the user selects, it is preferable to display a list of electronic dictionaries on the display unit 16 so that the user can select. Alternatively, each dictionary name may be displayed on a tab on the screen and selected by the user.

  In the first embodiment, since the search word is converted into English or Japanese, when the search word input in step S11 is a reading of hiragana, the electronic dictionary is stored in the storage unit 12e. Use Japanese-English dictionary data. In the case of spelling, the electronic dictionary uses English-Japanese dictionary data. When the second dictionary is determined in this way, each of the synonyms obtained in the first search is searched, and the headwords existing in the second dictionary by the comparison unit 18 are marked with a circle, If it does not exist, x is marked and search candidates are narrowed down (S16). The result of adding ◯ and X in this way is shown in Table b in FIG. Table b is for explicit indication, and processing is performed in the electronic dictionary such that the synonym stored in the synonym pattern candidate holding unit is left with a circle mark and the x mark is deleted. Alternatively, a process of setting a flag “1” for the mark “◯” and a flag “0” for the mark “X” is performed. The first search results are narrowed down in this way, and the narrowed headwords are stored in the storage unit 14 constituting the search candidate headline storage unit and displayed on the display unit 16 (S17).

In the flowchart, details of steps S12 to S14 will be described using the flowchart of FIG.
First, in step S21, it is determined whether the input search word is a hiragana reading or a spelling. In the case of reading hiragana, the process proceeds to step S22, and the synonym dictionary used in the first search is set to the “synonym new dictionary” of the Japanese language system. If it is a spell, the process proceeds to step S23, and the synonym dictionary is set to an English-type “modern thesaurus”. In step S24, the user specifies the genre of the search term. The genre designation of the search term is to designate the field of use of the search term as shown in FIG. In the case of FIG. 6, regarding “examine”, the genre includes “performance”, “trial”, “survey”, and “question and answer”. The user selects from these genres. Depending on the search term, there may be no genre. If there is no genre, the process proceeds to the next step S25 without specifying the genre. Next, a first search is performed for the designated genre using the dictionary set in step S22 or S23 (S25). It is determined whether or not a search result is obtained by the first search (S26). If the search result is obtained, the process proceeds to step S27. If, in step S26, the synonym dictionary set for the search word is used and the search result is not obtained in the specified genre, for example, an alert “specified dictionary, not found in specified genre” is alerted. Is displayed and the process ends.
In step S27, the headword of the synonym obtained by searching is stored in the storage unit 13 constituting the synonym pattern candidate holding unit. Next, in step S28, the next synonym is searched, and the process proceeds to step S29. In step S29, it is determined whether or not the next synonym ends. When there is no next synonym, it is determined that the process is over, and the listing by the first search is terminated. If there are more synonyms in step S29, the process returns to step S27, and the synonym list-up by the first search is repeated.

Next, the operation of narrowing down the synonyms obtained by the first search in the second search in steps S15 to S16 will be described using the flowchart of FIG.
First, in step S31, it is determined whether or not the dictionary used for the second search is designated by the user. If not specified, a dictionary set in advance as a default in the electronic dictionary in the next step S32 is used. For example, if the input search word is a reading of hiragana, and the Japanese language system is set, a Japanese-English dictionary is used. If the spelling is entered and the English language is used, the English-Japanese dictionary is set to be used. If the dictionary used in the second search is specified in step S31, the specified dictionary is displayed on the top tabs of the plurality of display tabs arranged at the top of the display unit 16. If not specified, the dictionary set in step S32 is displayed on the top tab. FIG. 8A shows a display screen of the display unit 16, and a tab 31 of a Japanese-English dictionary, a tab 32 of a Japanese-French dictionary, and a tab 33 of a national language dictionary are used at the top of the screen. FIG. 8A shows that the Japanese-English dictionary is the top tab 31.

  Next, in step S33, other dictionaries stored in the electronic dictionary, such as a Japanese-French dictionary and a Japanese language dictionary, are displayed on the tabs 32 and 33 following the top tab (S34). Next, the electronic dictionary reads the designated dictionary from the storage unit 12 (S35). In the next step S36, it is determined whether or not to end the dictionary selection. When the dictionary selection is finished, the process proceeds to step S40. If the selection of the dictionary is not completed, the process proceeds to step S37, where it is determined whether the national language dictionary and the English dictionary match the conditions preset in the electronic dictionary. That is, it is determined whether or not the dictionary is a Japanese language dictionary for Hiragana readings and an English dictionary for spelling inputs. If YES in step S37, the process advances to step S38 to determine whether the dictionary selected in step S35 is the same as the designated dictionary. If it is not the same as the designated dictionary, the process proceeds to step S39, the next dictionary displayed on the display tab is set, and the process returns to step S35. If the Japanese language dictionary and the English language dictionary do not match the preset conditions in step S37, or if the specified dictionary is the same in step S39, the process returns to step S35.

  In step S40, if the condition is set so that the dictionary of the SD card inserted into the electronic dictionary is also the search target dictionary, it is determined in step S47 whether or not the SD card is inserted. If the SD card is inserted, it is determined in the next step S48 whether a dictionary exists in the SD card. If the dictionary exists, it is determined in the next step S49 whether or not the dictionary matches the conditions of the Japanese language dictionary and the English language dictionary. If they match, the process proceeds to step S50, and the SD card is set as the next dictionary in the display tab shown in FIG. If the SD card is not inserted in step S47, if there is no dictionary in step S48, or if the Japanese dictionary and the English dictionary do not match the preset conditions in step S49, the process proceeds to the next step S41. Instead of the SD card, a semiconductor element memory, a magnetic recording body, or an optical recording body may be used.

  In step S41, the synonym list obtained by the first search is read. In step S42, one synonym in the synonym list is read out. In the next step S43, it is determined whether or not the listed synonyms are finished. If not, the second search is performed using a dictionary in which the synonyms are designated in the next step S44. As a result of the second search, if the synonym exists in the dictionary, the process proceeds to step S46, and the headword obtained from the search result is stored in the storage unit 14 constituting the search candidate headline holding unit. Then, the process returns to step S42, and the second search is repeated for the next synonym. In step S45, if no search result is obtained from the dictionary specified for the synonym, the process returns to step S42. When the second search is finished for the synonyms listed in the first search result in this way, the end is determined in step S43, and the second search is finished. If no search result is obtained in the second search, for example, “There is no search word in the Japanese-English dictionary” is displayed.

When the first search and the second search are completed by the above operation, a synonym batch search tab 30 and a Japanese-English dictionary tab 31 are displayed at the top of the screen as shown in FIG. Tab 30 represents the first search and tab 31 represents the second search. The headword extracted by the second search is displayed at the center of the screen of the Japanese-English dictionary tab 31 (S51). The headword displayed here is a synonym of “Search” and a headword that matches the Japanese-English dictionary. This is represented as step S51 in the flowchart of FIG.
In this state, the electronic dictionary enters a key input standby state (S52). The user uses the up / down cursor provided in the operation unit of the electronic dictionary (S53) to move the number of headwords up and down to select a desired headword (S54). Next, the user presses the “search / decision” key, which is “ENTER” (S55). Alternatively, a numeric key is pressed instead of the up / down cursor (S56). In FIG. 8A, it is assumed that “Kento (consideration)” is selected. By this operation, the selected desired headword is converted into English as shown in FIG. 8B, and English is displayed as shown in FIG. 8B (S57). When selecting this headword, according to the present invention, all English conversion results can be obtained. In this way, it is possible to search for an English word “study” having the meaning of “investigation / examination” that could not be found by “searching” entered as a search word by the user.

Further, when the return key of the electronic dictionary is operated on the display screen of FIG. 8A (S58), the search mode of the present invention is exited and the screen returns to the original search word input screen (S59). When the switch key is operated (S60), as shown in FIG. 8C, a Japanese-French dictionary is selected, and a third search is performed using the Japanese-French dictionary (S61). Headwords that can be searched in the Japanese-French dictionary by this third search are displayed as shown in FIG. 8C (S62). As can be seen by comparing FIG. 8A and FIG. 8C, the headwords that can be searched in the Japanese-English dictionary and the headwords that can be searched in the Japanese-French dictionary are different. In this way, since the multilingual dictionary can be switched, it is possible to input a single search word and perform a multilingual search using the dictionary installed in the electronic dictionary.
When a headword is selected with the up and down cursors or numeric keys on the screen of FIG. 8C (S63) and the “Search / Determine” key that is “ENTER” is pressed (S64), as shown in FIG. 8D. Is converted into French (S65). Further, when the switch key is operated (S66) and the national language dictionary is selected (S67), as shown in FIG. 8 (e), a synonym of “search” is displayed, and the meaning of “examine” is in the lower part. It is displayed (S68).

FIG. 9 shows that a spelling is entered into a search term, a first search is performed using a first dictionary, eg “modern thesaurus”, and then a second dictionary, eg “English-English dictionary” is used. An example of the second search is shown.
In FIG. 9A, “search” is input, the “modern dictionary” is used as the first dictionary, the synonym of “search” is searched, and then the second search is “English-English dictionary”. ”Is used to show a screen displaying searchable headwords. When “quest” is selected in FIG. 9A, an “English-English dictionary” is searched, and as shown in FIG. 9B, example sentences, meanings, and the like are displayed as search results. In FIG. 9A, when an English-Japanese dictionary is selected as the third dictionary used for the third search, the third search is performed, and the headwords that can be searched in the English-Japanese dictionary are shown in FIG. 9C. Is displayed. When the user selects a desired entry word from this entry word, the English-Japanese dictionary is searched and converted into Japanese, and FIG. 9D is displayed. When an English-French dictionary is selected, headwords that can be searched in the English-French dictionary are displayed as shown in FIG.
In the first embodiment, the third search is performed on the first search result, but the third search may be performed on the second search result. In the case of the third search, the dictionary used in the second search may be used, or a different dictionary may be designated.

(Embodiment 2)
In the second embodiment, a search word is input, a first search is performed for the search word using the first dictionary, the search result is displayed on the first display unit, and then the first search result is displayed.
