Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to selection of a search character string before performing a dictionary search based on a character string selected from text data, and a search character string selection device that allows a user to easily select a search character string, and the same The present invention relates to an electronic dictionary, a search character string selection method, a search character string selection program, and a recording medium recording the same.
[0002]
[Prior art]
In an electronic dictionary that allows you to check the meaning of words, terms, etc. with just a simple input, enter the character string that the user wants to check, search for that character string, and from the dictionary data built in the electronic dictionary, The corresponding one or more headwords are displayed on the screen of the display device. Then, when the user selects one of the headwords whose meaning is to be examined, an explanatory text corresponding to the headword can be displayed on the screen of the display device.
[0003]
In such an electronic dictionary, as a method for more easily searching for the meaning of terms, etc., a jump function unique to the electronic dictionary is provided, in which a search is performed by specifying a character string to be searched from sentences displayed on the screen. There is a search method used.
[0004]
This jump function does not return to the screen for directly entering the character string to be searched, but the character string whose meaning is to be examined by using pointing means such as a cursor from the text displayed directly on the screen. This is a function for selecting and performing a search.
[0005]
As a method using this jump function, for example, a method of manually moving a cursor to specify a range of a character string to be searched from within a sentence, or a character starting from one character selected in a sentence displayed on the screen Extract a string in order of a 1-character string, 2-character string, ..., n-character string, display all the character strings that exist as headwords in the dictionary, and then search by the user There is a method of selecting a character string to perform (see Patent Documents 1 and 2).

[0008]
[Problems to be solved by the invention]
However, the method disclosed in the above publication has the following problems from the viewpoint of usability.
[0009]
That is, the above-described method for performing a search by specifying a range of character strings to be manually searched has the following problems.
[0010]
For example, in a sentence “… triboelectricity, discharge / current, etc.”, when searching for a character string “frictional electricity”, the cursor is first moved to “ma” to determine the first character position. Then, since it is necessary to move the cursor to “Qi” and determine the last character position, it is very troublesome to specify the character string range.
[0011]
Furthermore, even if a character string is specified, the character string is not necessarily included as a heading of the stored dictionary data, so that there may be a case where the search cannot be performed. It is impossible for the user to determine whether or not the character string can be searched before executing the search, that is, whether or not the character string exists as an entry word in the dictionary data.
[0012]
Further, in the method disclosed in the above publication, since it is necessary to designate a range of a character string to be jumped, the operation is very troublesome particularly when a long character string is designated.
[0013]
On the other hand, the method of displaying a list of all character strings existing as headwords in the dictionary data for a character string starting from a specified character has the following problems.
[0014]
That is, first, the cursor is moved to “ma” which is the first character of the character string to be searched. Here, when a search is executed, a character string starting from “ma” and a character string existing as an entry word are candidates, and for example, a large number of character strings such as “friction electricity”, “friction”, and “ma” are selection candidates. A list is displayed.
[0015]
Here, such a jump function can be used to check the reading kana and meaning when the user does not know the reading kana in the sentence or when there is a long compound word whose meaning is to be checked. Many.
[0016]
Therefore, in consideration of such circumstances, it is considered that there are few users who search for words or phrases such as “ma” and “friction” listed in the above sentence. Therefore, in the method of selecting a character string to be searched from such a list displayed, it is necessary for the user to select the character string to be searched from among all the character strings that are unlikely to be selected. Yes, it is inefficient.
[0017]
The present invention has been made in view of the above-described problems, and an object of the present invention is to enable specification of a character string to be searched by simply moving the cursor and specifying the first character of the character string. It is an object of the present invention to provide a search character string selection device and an electronic dictionary provided therewith, a search character string selection method, a search character string selection program, and a recording medium recording the same.
[0018]
[Means for Solving the Problems]
In order to solve the above-described problem, the search character string selection device of the present invention is a search character string selection device that selects a character string to be searched from text data. First character input means for inputting a character, a character string included in the sentence data having an arbitrary character input to the first character input means as a first character, and a headword of search information in an external storage unit A character string determination unit that determines whether or not the stored character string matches, and a search character string selection unit that selects the matched character string as a search character string when the character string determination unit determines that they match. It is characterized by having.
[0019]
According to the above configuration, when performing a term search or the like, the user simply stores the cursor on the first character of the character string to be searched in the text data and is stored as dictionary data in a storage means such as a ROM. It is possible to automatically select a character string that matches a character string existing as an entry word of the information. For this reason, the user can select and search for a searchable character string in advance, and save the trouble of specifying the range of the search character string, and improve the operability when performing a term search. be able to.
[0020]
That is, in the search character string selection device of the present invention, for example, when searching for the meaning of a term, the user moves the cursor or the like via the selected character string input means to perform the term search. Specifies the first character of the column.
[0021]
Then, the character string determining means includes a character string that is included as a headword in dictionary data as search information stored in advance in a storage unit such as a ROM among character strings starting from a character specified by the cursor on the screen by the user. It is determined whether or not there is a match.
[0022]
Here, if the character string determination means determines that a character string matching the character string in the sentence data starting from the first character specified by the user exists as a headword in the dictionary data, the search character string selection unit The matched character string is selected as a search character string.
[0023]
As a result, the user can automatically select a searchable character string as a search character string by simply placing the cursor on the first character of the character string to be searched, and therefore manually select the range of the search character string. Compared with the conventional method, user operability can be improved.
[0024]
In the search character string selection device of the present invention, only a searchable character string that matches a headword corresponding to search information stored in advance as dictionary data is selected as a search character string. Although the search is performed by designating, the corresponding information is not stored, and it is possible to prevent the occurrence of a problem that the search cannot be performed. Therefore, useless search execution can be prevented and search processing can be performed efficiently.
[0025]
Furthermore, since the search character string can be selected instantly by simply moving the cursor and displayed on the screen using a method such as highlighting the selected character string, the selected search character string can be visually easily displayed. It becomes possible to confirm.
[0026]
More preferably, the first character input means inputs an arbitrary character selected from the document data.
[0027]
Thus, the user does not need to specify the range of the search character string, and can easily select the search character string simply by moving the cursor.
[0028]
More preferably, a maximum number of characters input means for setting the maximum number of characters of the character string to be searched is provided.
[0029]
As a result, by setting the maximum number of characters of the character string to be searched in advance before searching, the character string of the set maximum number of characters starting from the first character specified by the user is cut out and found in the dictionary data. A search character string can be selected by determining whether there is a character string that matches a character string stored as a word.
[0030]
When the character string determination means determines that there is no entry word that matches the maximum number of characters starting from the first character, the character string determination means subtracts one character from the selected search character string. More preferably, the character string is subjected to the same determination as described above.
[0031]
Accordingly, the determination can be started from a character string having the maximum number of characters inputted in advance, and the same determination can be performed by reducing the number of characters one character at a time until a matching entry word is found.
[0032]
Therefore, since the longest character string is preferentially selected from a character string of the maximum number of characters or less that is set in advance, even when selecting a character string such as a compound word with a large number of characters as a search character, a long character string manually It is not necessary to specify the range of, and is particularly effective.
[0033]
When an instruction to reduce the number of characters in the character string is input in a state where the search character string is selected, the character string determination unit includes a character string obtained by reducing the number of characters in the selected character string by one character More preferably, the headword is compared.
[0034]
As a result, if you want to select a character string shorter than the currently selected character string as the search character string, you can easily reduce the selection range by moving the cursor, and use the new character string as the search character string. You can choose.
[0035]
It is more preferable that a search information group attribute determination unit that determines an attribute assigned to each group of search information stored in the external storage unit is provided.
[0036]
Thus, even when dictionary data based on a plurality of dictionaries is stored in an external storage unit such as a ROM, for example, it is selected as a search character string based on the result determined by the search information group attribute determination means. The display of the character string can be changed.
[0037]
Therefore, the user can easily grasp the dictionary data based on which dictionary stored in the storage unit is the character string selected as the search character string.
[0038]
Further, when the search character string is determined and the explanatory text corresponding to the headword is displayed, the dictionary is automatically determined according to the attribute attached to the currently selected search character string. Therefore, since the user can directly perform a search without going through a screen for selecting a search destination dictionary, it is possible to omit useless operations.
[0039]
The attribute is assigned to each dictionary as a search destination by, for example, a method of displaying a search character string in a specific color / typeface.
[0040]
In order to solve the above problems, an electronic dictionary of the present invention includes a search character string selection device, a key input unit that performs key input to the search character string selection device, and a storage unit that stores the dictionary data. It is characterized by having.
[0041]
Accordingly, it is possible to realize an electronic dictionary including the search character string selection device that allows the user to easily select a search character string by simply placing the cursor on the first character of the character string to be searched.
[0042]
In order to solve the above-described problem, the search character string selection method of the present invention is a search character string selection method for selecting a character string to be searched from sentence data. A first step in which an arbitrary character selected from among the first character is input; and a character string determination unit, a character string in the sentence data having the arbitrary character input to the first character input unit as a first character; The second step of determining whether or not the character string stored as the headword of the search information in the storage unit matches, and the search character string selection unit determines that the character string determination unit matches, And a third step of selecting a matched character string as a search character string.
[0043]
According to the above method, for example, when performing a term search or the like, the user simply stores the cursor on the first character of the character string to be searched in the sentence data and stores it as a dictionary data in a storage means such as a ROM. It is possible to automatically select a character string that matches a character string that exists as an entry word of the information being recorded. For this reason, the user can select and search for a searchable character string in advance, and save the trouble of specifying the range of the search character string, and improve the operability when performing a term search. be able to.
[0044]
That is, according to the search character string selection method of the present invention, for example, when searching for the meaning of a term or the like, the user moves the cursor or the like via the selected character string input means to perform the term search. Specify the first character of the string to be executed.
[0045]
Then, the character string determination means includes a character string that is included as an entry word in dictionary data as search information stored in advance in a storage unit such as a ROM, among character strings starting from a character specified by the user with a cursor on the screen. It is determined whether or not there is a match.
[0046]
Here, if the character string determination means determines that there is a character string in the dictionary data that matches the character string in the sentence data starting from the first character specified by the user, the search character string selection unit The selected character string is selected as a search character string.
[0047]
As a result, the user can automatically select a searchable character string as a search character string by simply placing the cursor on the first character of the character string to be searched, and therefore manually select the range of the search character string. Compared with the conventional method, user operability can be improved.
[0048]
In the search character string selection method of the present invention, only the searchable character string that matches the headword corresponding to the search information stored in advance as dictionary data is selected as the search character string. Although the search is performed by designating, the corresponding information is not stored, and it is possible to prevent the occurrence of a problem that the search cannot be performed. Therefore, useless search execution can be prevented and search processing can be performed efficiently.
[0049]
Furthermore, since the search character string can be selected instantly by simply moving the cursor, and the selected character string is displayed on the screen using a method such as highlighting the selected character string, the selected search character string can be visually easily displayed. It becomes possible to confirm.
[0050]
The search character string selection program according to the present invention is characterized by causing a computer to execute the search character string selection device in order to solve the above problems.
[0051]
According to said structure, the selection apparatus of the said search character string is realizable with the said program.
[0052]
In order to solve the above-described problems, the recording medium of the present invention is characterized by recording a search character string selection program that causes a computer to execute the search character string selection device.
[0053]
According to the above configuration, the search character string selection device can be realized by the search character string selection program read from the recording medium.
[0054]

[0058]
The display 12 displays on the screen based on the display data transmitted from the control unit 11. For example, the display is performed based on text data input via the key input unit 14.
[0059]
The display controller 13 receives display data to be displayed on the display device 12 from the control unit 11 and controls the display device 12.
[0060]
The key input unit 14 includes an ON key 25, an OFF key 26, a function key 27, an alphanumeric key 28, a first character designation cursor call key 29, and the like.
[0061]
The ON key 25 and the OFF key 26 are used when the electronic dictionary 10 is turned on / off. The ON key 25 and the OFF key 26 may be provided as a single ON / OFF key that can be turned ON / OFF by a software process such as a long key press.
[0062]
The function key 27 includes a menu key for switching dictionary contents for searching for a headword and various settings.
[0063]
The alphanumeric key 28 is used to input alphabets and numbers from A to Z and some symbols.
[0064]
The first character designation cursor call key 29 makes a cursor appear on the screen for designating a character string for the user to search from sentences displayed on the screen of the display device 12.
[0065]
The ROM 15 is a dictionary data including a program 31 for operating the control unit 11, search information including term descriptions, word meanings, and the like, and a character string corresponding to the search information (hereinafter referred to as a headword). 32 is stored.
[0066]
The ROM 15 stores search information (information on character strings) such as headwords and term explanations as dictionary data 32, and an index that collects headwords of each search information as shown in FIG. Are stored separately.
[0067]
The “search information” is, for example, information on the meaning of a term if the stored dictionary data is a term dictionary, and information on the meaning of an English word if the stored dictionary data is an English-Japanese dictionary It is.
[0068]
On the other hand, since the index is used only when selecting a character string when jumping, in addition to the normal dictionary data 32, as shown in FIG. Are stored in the ROM 15 as a list obtained by re-editing the addresses indicating the locations where the headwords and the semantic information of the headwords are stored.
[0069]
The RAM 16 is used as a memory for storing data such as headwords searched by the user, the maximum number of extracted characters input by the user, a character string starting from the first character specified in the sentence, or the like, or as a work memory of the control unit 11. It is done.
[0070]
The battery 17 supplies power to the electronic dictionary 10.
[0071]
Here, in the electronic dictionary 10 of the present embodiment, the control unit 11 executes various application programs using a memory such as the ROM 15 and the RAM 16 and controls the hardware such as the display unit 12, thereby The function is realized.
[0072]
That is, as shown in FIG. 1, the control unit 11 includes a first character input unit (first character input unit) 2, a maximum character number setting unit (maximum character number setting unit) 3, and a character string determination unit (character string determination unit) 4. A search character string selection unit (search character string selection unit) 5 and a dictionary attribute determination unit (search information group attribute determination unit) 6 are formed as functional blocks.
[0073]
The first character input unit 2 is input with the first character of the character string to be searched, which is designated by the user via the key input unit 14.
[0074]
The maximum character number setting unit 3 sets the maximum number of characters for extracting a character string to be searched that is input by the user via the key input unit 14.
[0075]
The setting of the maximum number of characters by the user is performed on the input screen as shown in FIG. 2, and the number of characters is set for each dictionary in which the search information is posted as the dictionary data 32, and the table as shown in FIG. Stored in the RAM 16.
[0076]
The character string determination unit 4 compares the character string starting from the first character input to the first character input unit 21 with the entry word in the dictionary data 32 stored in the ROM 15 and determines whether there is a match. Do.
[0077]
The search character string selection unit 5 extracts a character string equal to or less than the maximum number of characters preset by the user from a plurality of character strings determined to be matched by the character string determination unit 22, and searches for the longest character string among them. Display as a string.
[0078]
The dictionary attribute determination unit 6 determines, in the dictionary data 32 stored in the ROM 15, the attribute assigned to each search destination dictionary such as Kojien (registered trademark) or English-Japanese dictionary as shown in FIG. 10. The processing using the dictionary attribute determination unit 6 will be described later.
[0079]
Here, a method for selecting a search character string by the electronic dictionary 10 having the above configuration will be described as follows with reference to a flowchart shown in FIG.
[0080]
That is, in the electronic dictionary 10 of the present embodiment, when a character string to be searched for is selected from sentences displayed on the screen of the display device 12, processing is performed in the following procedure.
[0081]
First, in S1, the user presses the first character designation cursor call key 29 of the key input unit 14. Then, the control unit 11 causes the cursor to appear on the display screen of the display device 12.
[0082]
Next, the user uses the key input unit 14 to align the cursor with the first character of the character string to be searched in the text displayed on the screen, and inputs the selected character to the first character input unit 21. Then, the control unit 11 determines whether or not the cursor has moved from the current position in S2.
[0083]
Here, when the cursor has not moved, since the first character is not designated, the control unit 11 repeats S2 until movement of the cursor is detected.
[0084]
On the other hand, when the cursor has been moved by the user, the control unit 11 determines whether or not the maximum number of characters N of the search character string preset by the user, that is, the number of characters of the character string to be extracted is 1 in S3. Determine whether or not.
[0085]
In S3, when the control unit 11 determines that the number N of characters in the character string is 1, the search character string selection unit 5 displays the character string on the display screen of the display 12 via the display controller 13 in S4. One character is selected as a search character string and displayed in reverse video, and the process ends.
[0086]
On the other hand, if the control unit 11 determines that the number N of characters in the character string is not 1, the control unit 11 selects the character at which the cursor is located from the text displayed on the display unit 12 in S5. A character string of N characters is cut out and stored in the RAM 16.
[0087]
Next, in S6, the character string determination unit 4 searches the index stored in the ROM 15 for a headword consisting of the same character string as the character string cut out from the text stored in the RAM 16, In S <b> 7, it is determined whether or not a headword that matches the character string cut out from the sentence exists in the dictionary data 32.
[0088]
If the character string determination unit 4 determines in S7 that the matching headword exists, the search character string selection unit 5 selects the character string as a search character in S8.
[0089]
And the control part 11 reverse-displays the selected character string in the text displayed on the display screen of the indicator 12 via the display controller 13, and complete | finishes a process.
[0090]
On the other hand, if the character string determination unit 4 determines in S7 that there is no matching headword in the index, the control unit 11 decreases the preset maximum number of characters N by 1 in S9 and returns to S3. Repeat the same process.
[0091]
That is, if the preset maximum number of characters is 2 or more, S3 to S7 are repeated until a matching character string is found in the index while reducing the number of characters in the character string to be searched one by one.
[0092]
For example, as shown in FIG. 6A, in a sentence having “Internet” as a headword, the user has set the maximum number of characters N to 5 in advance, and puts the cursor on “Den” and issues a search instruction. In this case, the five-character “e-mail” having “Den” as the first character is automatically selected as the search character by the search character string selection unit 23 and displayed on the display 12 via the display controller 13. It is highlighted on the screen.
[0093]
Therefore, if the character string to be searched by the user is “e-mail”, the search process may be executed as it is.
[0094]
Further, even when the maximum number of characters is set to 6 or more and the user desires to search for “e-mail”, “e-mail etc. with the first character“ den ”specified by the user ... Among the character strings “”, the character string stored in the dictionary data 32 is likely to be only “e-mail”. For this reason, even when the maximum number of characters is set to 6 or more, the number of characters is decreased one by one in S9 of the flowchart until the character string stored in the dictionary data 32, that is, “e-mail” is found. S3 to S7 in FIG. 5 are automatically repeated. Therefore, as a result, as shown in FIG. 6A, the character string “e-mail” is similarly selected as a search character and is displayed in reverse video on the display screen of the display device 12. Therefore, the search is started as it is. it can.
[0095]
As described above, in the electronic dictionary 10 of the present embodiment, the user can automatically select a desired character string “e-mail” as a search character by simply placing the cursor on the first character of the character string to be searched. The operability when executing the search can be improved.
[0096]
Moreover, in the electronic dictionary 10 of this embodiment, only the character string which matches the character string contained in ROM15 as the dictionary data 32 is selected as a search character among the character strings which the user designated the first character. For this reason, as a result of searching by specifying a character string, there is no problem that the character string is not stored in the dictionary data 32 as an entry word and cannot be searched. Therefore, it is possible to eliminate time loss due to the inability to search and improve search efficiency.
[0097]
Furthermore, in addition to the processing described above, the electronic dictionary 10 according to the present embodiment has a function of easily selecting a desired search character string by changing the number of characters in the selected character string.
[0098]
That is, when an arbitrary character string “e-mail” is selected by the above-described processing, pressing a key for reducing the selection range such as the left arrow key causes shorter character strings “electronic” and “electric”. It has the function which can select easily.
[0099]
That is, for example, when the user desires to search for “electronic” and the maximum number of characters N is set to 5 or more, as described above, the character string “e-mail” Are displayed in reverse on the display screen of the display 12 as a search character string.
[0100]
However, since the user wants to search for “electronic”, the search cannot be performed as it is.
[0101]
Therefore, in the electronic dictionary 10 of the present embodiment, as shown in FIG. 6A, when the character string “e-mail” is highlighted on the display screen of the display device 12, A search character string in the order of “electronic” and “electric”, as shown in FIGS. 6B and 6C, simply by pressing the direction of expanding / contracting the character string, that is, in this case, the left direction key. Can change.
[0102]
For this reason, when a character string different from the character string desired by the user is first highlighted as a search character string, for example, as shown in FIG. As shown in FIG. 6 (c), the character string “mail” desired to be searched is selected as the search character string by pressing the right arrow key twice from the state highlighted on the display screen as the search character. In addition, it can be displayed in reverse on the display screen and search can be executed.
[0103]
The processing shown in FIGS. 6A to 6C by the electronic dictionary 10 of this embodiment will be described as follows with reference to the flowchart shown in FIG.
[0104]
First, in step S10, the control unit 11 checks whether or not the user has pressed the direction key to reduce the range of the selected character string “e-mail”.
[0105]
Here, the check is repeated until the key is pressed to the side of reducing the selection range.
[0106]
In S10, when the control unit 11 detects that the key has been pressed to reduce the selection range, in S11, the control unit 11 calculates the number of characters L of the character string “e-mail” that is highlighted on the display screen of the display unit 12. In S12, a value obtained by subtracting one character from L is set to L again.
[0107]
That is, the number of characters in the character string “e-mail” is reduced by 1, and the selection range is changed to the character string “e-mail”.
[0108]
In step S13, the control unit 11 checks whether the number of characters L is zero.
[0109]
Here, when L is 0, it means that the original selected character string is one character, and therefore the number of characters cannot be reduced any more. Therefore, the control part 11 moves a cursor to the left in S14, and complete | finishes a process.
[0110]
On the other hand, if L is not 0, the control unit 11 cuts out a character string “electronic mail” having the number of characters L, which is one character less than the character at which the cursor is located, and stores it in the RAM 16 in S15.
[0111]
Next, in S16, the character string determination unit 4 selects the character string “electronic” stored in the RAM 16 from the index composed of the headword whose first character is the character where the cursor is stored, which is stored in the ROM 15. Search for “Me”. In step S17, it is determined whether there is a matching character string in the index.
[0112]
If there is a matching character string, the control unit 11 reduces the range of the selected search character string in S18, and the search character string selection unit 5 sets this as a new search character string. This is selected and displayed in reverse video on the display screen of the display device 12, and the process is terminated.
[0113]
On the other hand, if the character string determination unit 4 determines that no matching character string exists as an entry word in the index, the control unit 11 decreases L by 1 in S19, returns to S13, and performs the same processing. repeat.
[0114]
In the above example, the headword that matches the character string “electronic mail” does not exist in the dictionary data 32. Therefore, in S19, the control unit 11 further reduces the number of characters by one and performs the same processing with the character string “electronic mail”. However, no matching word is found in the dictionary data 32 even with the character string “electronic mail”.
[0115]
Therefore, the control unit 11 further reduces one character in S19 and then returns to S13. The same processing is repeated, and the character string determination unit 4 determines whether there is a headword that matches the character string “electronic”. Since the dictionary data 32 includes data having the character string “electronic” as a headword, the search character string selection unit 5 selects the character string “electronic” as a new search character string and performs control. The unit 11 can reverse-display the selected character string on the display screen of the display device 12.
[0116]
The above-described processing is executed by the control unit 11 reading a program. Therefore, in actuality, when the user designates the first character, the selected search character string is selected immediately by the above processing with almost no time until it is displayed in reverse on the display screen of the display 12. You can see the search string on the display screen.
[0117]
Similarly, when the search character string is changed from the character string “e-mail” to the character string “electronic”, the user simply presses the left arrow key and immediately inverts “electronic” as a new search character string. Can be displayed.
[0118]
Therefore, even if the desired search character string is not selected at the first time, the user can easily select the next search character string by simply pressing the direction key once or several times. , Search efficiency can be improved.
[0119]
Further, when the character string to be searched is not “e-mail” but “mail”, on the contrary, the first character set by the user is changed by pressing the right arrow key.
[0120]
Thus, by performing the same process as the process shown in FIG. 5 for the new first character, the character string “child” shown in FIG. 8B is changed from the character string “e-mail” shown in FIG. The character string “mail” shown in FIG. 8C and the search character string selected in sequence can be changed.
[0121]
Here, another search function by the electronic dictionary 10 of the present embodiment will be described as follows.
[0122]
The electronic dictionary 10 of this embodiment is equipped with data based on a plurality of different dictionaries as the dictionary data 32 stored in the ROM 15. For this reason, when a single character string is selected and a search is executed, there may be a plurality of dictionaries having the same entry word in the ROM 15.
[0123]
Therefore, in the electronic dictionary 10 of the present embodiment, an attribute is set in advance for each dictionary stored as dictionary data, and the dictionary-specific attribute determination unit 6 is provided in the control unit 11 shown in FIG. It has a function of determining whether it is information and displaying it to the user.
[0124]
Further, the dictionary-specific attribute determination unit 6 realizes a function of automatically determining a search destination dictionary according to the attribute displayed at the time when the selected character string is searched. ing.
[0125]
For example, when a broad dictionary, an encyclopedia, and an English-Japanese dictionary are stored in the ROM 15 as a search destination for the character string “e-mail”, the wide dictionary is black, as shown in FIG. 9A. As shown in FIG. 9, the encyclopedia is red, and the Japanese-English dictionary is blue as shown in FIG.
[0126]
This eliminates the need for the user to open a dictionary selection screen and select a dictionary to be searched, and can select a search character string more efficiently.
[0127]
For the attributes set for each dictionary, the dictionary name and the color assigned to each dictionary may be stored in the RAM 16 as a setting table, as shown in FIG.
[0128]
Moreover, in the electronic dictionary 10 of this embodiment, although color is used as an attribute attached to each dictionary, the present invention is not limited to this.
[0129]

[0131]
First, in S20, the control unit 11 stores in the RAM 16 a dictionary name having a character string currently selected as a search character as an entry word.
[0132]
Next, in S <b> 21, the dictionary attribute determination unit 6 determines whether the dictionary A exists in the dictionary name stored in the RAM 16.
[0133]
Here, when the dictionary A exists, in S22, the control unit 11 displays the character string with the attribute corresponding to the dictionary A for a certain period of time, and in S23, determines to instruct to display the explanatory text therebetween. Check whether a key or the like has been pressed.
[0134]
If the determination key is pressed, in S24, an explanatory note is displayed as search information corresponding to the search character string from the dictionary A corresponding to the character string, and the process is terminated.
[0135]
On the other hand, if the attribute-by-dictionary determination unit 6 determines in S21 that the dictionary A does not exist, or if the user does not wish to search the dictionary A and the determination key is not pressed in S23, the dictionary For B and dictionary C, the same processing as S22 to S24 is performed in S26 to S28 and S30 to S32.
[0136]
If the user does not want to search all the dictionaries A to C, the process returns to S21 and the same process is repeated or the search character string is changed and the process from S21 is repeated again.
[0137]
As described above, according to the electronic dictionary 10 of the present embodiment, the user can search for a character string by specifying a dictionary for which he / she wants to obtain search information. It can be easily searched and provided.
