(Combination of search method and character type)
In the present embodiment, the search method is made different for each character type of the search phrase. A table 300 in FIG. 6 shows an example of combinations of character types of search terms and search methods. The table 300 is stored in a predetermined area of the main storage unit 103.

  Referring to FIG. 6, table 300 is a search method (collective) using data 301 representing character types (Japanese, Kana-Kanji conversion characters, English characters, Chinese characters, Pinyin characters) and search terms of the character types. , Full text, example sentence, phrase) and data 302 are shown. The determination unit 221 searches the table 300 based on the character type selected by the search character type selection tab 190, that is, the character type of the search phrase input to the search editor 200, and is associated with the data 301 representing the character type. The data 302 of the search method is read out. As a result, one or more types of search target items corresponding to the character type are determined. For example, when the character type is “Japanese”, according to the table 300, the item excluding the item “sung phrase” is determined as the search method. For the character type “English”, “collective”, “full sentence”, “example sentence”, and “sung phrase” are all determined as search methods. According to the table 300, the search target item, that is, the search method can be determined (determined) based on the character type.

(About basic operation)
The dictionary search operation of electronic dictionary device 100 according to the present embodiment includes a “first operation” and a “second operation”.

<First operation>
In the first operation, the search unit 220 sets the item search unit 222 so that a search operation for an item that is not a search target item becomes invalid. Further, the CPU 106 prohibits the operation of the tab of the item in the search method selection tab 180.

  FIG. 7 shows an initial screen of a dictionary search screen (“examine” screen). According to the table 300, since “collective” is included in the search target items for all character types, the collective tab 181 of the search method selection tab 180 is displayed in a standard form on the initial screen, and collective search is possible. Is presented to the user. In the search character type selection tab 190, the tab 191 is highlighted to notify that “Japanese” is initially designated as the character type. Further, only the cursor CR is displayed in the search editor 200, and the user is prompted to input a search phrase. When a character type other than “Japanese” is specified, the user can switch the character type from “Japanese” to a desired character type by operating the search character type selection tab 190. Therefore, it is assumed that the character type change operation is not performed.

  In the initial screen of FIG. 7, when Japanese “Toyo Tomi Hideyoshi” is input as a search phrase to the search editor 200, the screen is switched to the screen of FIG. 8. When “Hiragana” is input to the search editor 200, the determination unit 221 searches the table 300 based on “Japanese” which is the designated character type. Based on the search result, the third output control unit 233 switches the phrase tab 184 of the search method selection tab 180 to, for example, gray-out display (background is displayed in gray). As a result, it is notified that the search operation for the item of “sung phrase” is invalid. Although the invalid display mode is “gray-out display”, the display is not limited to this. For example, the design display of the tab may be deleted.

  The item search unit 222 relates to items including the search term “Toyoto Hidehide” among the search target items (“batch”, “full text”, “example sentences” excluding “sung phrase”) determined by the determination unit 221. The searched entry word 152 is searched from a plurality of dictionary contents 130. The output control unit 230 generates display control data for a list in which the headword 152 as a result of the search by the item search unit 222 and the identifier (dictionary name) of the dictionary content 130 from which the headword 152 is read out are associated with each other. Output to the display 107. The display 107 displays a list in the area 281 of the area 280 in FIG. 8 based on the display control data.

  When the user operates the key 113b in a state where a desired headword is selected from the list in the area 281, the search unit 220 searches the dictionary content 130 in which the selected headword 152 is stored for the search target of the headword 152. The contents of the items (“collective”, “full text”, “example sentence”) are read out. The read content is displayed in area 282 of area 280.

  Further, when the search target is narrowed down, the user selects a desired entry word 152 from the list in the area 281 and selects a tab (for example, the example sentence tab 183) corresponding to the desired item from the search method selection tab 180. When the key 113b is operated, the search unit 220 reads only the example sentence of the search target item (“example sentence”) of the entry word 152 from the dictionary content 130 storing the selected entry word 152. The second output control unit 232 generates display control data from the read information and outputs it to the display 107. Display 107 displays only the read example sentence in area 282 of area 280 based on the display control data.

  According to the <first operation>, when the user inputs “Toyo Tomi Hideyoshi” in the search editor 200, the phrase tab 184 is grayed out. When the user subsequently narrows down the search target, the user can quickly check the tabs that can be operated among the search method selection tabs 180, and can efficiently perform the tab operation.

<Second operation>
In the second operation, when searching for an item specified by the search method selection tab 180, the search unit 220 searches for other items excluding the search target item, and from the search result, The third output control unit 233 calculates (counts) the number of headwords 152 searched for by each search item. Then, the tab corresponding to the item in the search method selection tab 180 is switched to invalid display so that the search operation for the item whose calculated value is zero (also referred to as “no item”) becomes invalid. Control data is generated and the display 107 is controlled.

  Specifically, referring to FIG. 9 and FIG. 10, when “Toyo Tomi Hideyoshi” is input to the search editor 200, not only a search for the item “batch” currently selected by the user, , "Full sentence" and "example sentence" are also searched. As a result of the search, the number of headwords 152 read from the dictionary content 130 for each item is counted. For example, when the headword searched for “example sentence” is zero, the example sentence tab 183 is switched to gray-out display so that the narrow-down search for “example sentence” becomes invalid.

  According to the <second operation>, when the user inputs the kana character “Toyo Tomi Hideyoshi” to the search editor 200, the example sentence tab 183 and the character type of the item in which the searched headword 152 is zero. The idiom tab 184 of the item that is invalidated from the search is grayed out. When the user subsequently narrows down the search target, the user can quickly check the operable tabs in the search method selection tab 180, and can efficiently perform the tab operation.

(How to enter search terms)
The search phrase accepted by the phrase acceptance unit 251 is represented by a character string input by the user into the search editor 200. This character string includes a kana character string, a kana-kanji character string acquired by kana-kanji conversion, and a recognized character string obtained by recognizing handwritten characters by pattern matching, for example. When the electronic dictionary device 100 includes a sound collection unit such as a microphone, a character string obtained by recognizing input speech from the sound collection unit is included.

<How to input Kana-Kanji conversion characters>
FIG. 11 shows an outline of kana-kanji conversion processing by the phrase receiving unit 251 according to the present embodiment using a screen display example.

  First, when the “examine” screen is displayed (step SS1), the user operates the operation unit 202 to set the operation mode of the electronic dictionary device 100 to “kana-kanji conversion mode” (step SS2). At this time, the command receiving unit 253 receives a mode change command from the operation content, and the character type receiving unit 252 receives “kana-kanji conversion character” as the character type based on the mode change command. The first output control unit 231 controls the display 107 so that the tab 192 of the search character type selection tab 190 is highlighted based on the received content.

  Also, after setting the “kana-kanji conversion mode”, when the user operates the keyboard 114 to input the alphabet character string “TOYOTOMI”, the alphabet character string is converted into a Japanese kana character string and set in the search editor 200. (Step SS3).

  When the user subsequently operates the conversion key 113a, the command receiving unit 253 receives a Kana-Kanji conversion command based on the operation content. In accordance with the kana-kanji conversion command, the phrase receiving unit 251 searches the kana-kanji conversion dictionary content in the main storage unit 103 based on the kana character string “Toyotomi”, and corresponds to the kana character string “toyotomi”. The character string “Toyotomi” is read from the dictionary content. The read Kana character string is displayed on the search editor 200 (step SS4). Thereby, the phrase reception part 251 can receive the character string after Kana-Kanji conversion.

  When the user operates the key 113b, the command receiving unit 253 outputs a search command based on the operation content, and the search process by the search unit 220 is performed (step SS5). Specifically, the determination unit 221 determines “collective”, “entire sentence”, and “example sentence” as search target items from the table 300 based on the designated character type “character for Kana-Kanji conversion”. The item search unit 222 performs a batch search process based on the search term “Toyotomi” to identify items including the search term “Toyotomi” among the search target items “Batch”, “Full text”, and “Example sentence”. The headword 152 related to the item is read from the plurality of dictionary contents 130. The output control unit 230 generates display control data from the information read by the search (search result). Display 107 displays the search result in area 280 based on the display control data.

(Specific dictionary search processing)
The dictionary search processing will be described with reference to display screens (screens for accepting operations) on the display 107 in FIGS.

  First, when the user operates the key 114C, the initial “examine” screen of FIG. 12 is displayed on the display 107 (step S1). It is assumed that the user desires to input handwritten characters and operates the “handwriting” tab 211 of the input pad selection tab 210.

  CPU 106 sets areas 283a and 283b for handwritten input on the screen of FIG. 13 (step S2). Specifically, the CPU 106 sets a handwriting input pad in the area 283a, and displays various operation buttons for inputting instructions related to handwriting input in the area 283b. The operation buttons include a button 284 for instructing the start of handwritten character recognition processing and a button 285 operated to determine input contents for search. The function of the button 285 corresponds to the function of the key 113b. When the user operates the return key 113e when the screen of FIG. 13 is displayed, the process returns to step S1, and the screen is switched to the initial screen of FIG.

  The user operates the tab 191 to specify the character type “Japanese” and inputs characters by handwriting in the region 283a of FIG. 14 using the stylus pen 110 (step S3). When the user performs an operation of selecting the button 284 after handwriting input “Hideyoshi Toyotomi”, the CPU 106 shifts the processing to step S4 according to the operation content. In step S4, the screen of FIG.

  In step S4, the phrase receiving unit 251 starts a recognition process for handwritten characters in the region 283a in accordance with a recognition start command based on the operation content of the button 284. The phrase receiving unit 251 performs recognition processing for Japanese characters on the handwritten characters based on the character type “Japanese” designated by the tab 191. When the character string “Hideyoshi Toyotomi” is acquired as the recognition result, the character string is displayed in the search editor 200 of FIG.

  When the character string “Hideyoshi Toyotomi” is input to the search editor 200 of FIG. 15, when the user selects the button 285, the screen of FIG. 16 is displayed, and the process proceeds to step S5. At this time, the determination unit 221 searches the table 300 based on the designated character type “Japanese” and determines a search target item based on the search result. The first output control unit 231 causes the display 107 to display the determined type of the search target item. Specifically, among the tabs of the search method selection tab 180, the tab of the determined search target item is highlighted to notify that it is a search target. Further, the tabs of items that are not determined as search target items are invalidated by the third output control unit 233. In this case, according to the table 300, the example sentence tab 183 and the phrase tab 184 are invalidly displayed, and the tabs of the other items “collective” and “full sentence” are effectively displayed (non-grayed out). If the user operates the clear key 113d during the screen display of FIG. 15, the process returns to step S2, and the screen of the display 107 is switched to the screen of FIG.

  Referring to FIG. 16, in step S5, batch search processing by item search unit 222 is performed. Based on the result of the search, as shown in the above (second operation), the third output control unit 233 determines that the item search unit 222 has not searched for the related headword 152 and the determination unit 221. For items that are not determined as search target items, the display 107 is controlled so that tabs corresponding to these items in the search method selection tab 180 are grayed out. For example, the example sentence tab 183 corresponding to the item “example sentence” for which the related headword 152 has not been searched by the item search unit 222 and the phrase tab 184 of the item “sung phrase” not determined as the search target item by the determination unit 221 One is grayed out. The gray-out display informs that the search operation for the items “example sentence” and “sung phrase” is invalid.

  In FIG. 16, in the area 281, based on the search result, the headword 152 read from the dictionary content 130 and the dictionary name of the dictionary content 130 in which the headword 152 is stored are displayed in a list. Also, in the area 282, the sentence data of the entry word for the entry word 152 specified in the area 281, such as a commentary sentence, is read from the corresponding dictionary content 130 and displayed in the area 282.

  When the user operates the clear key 113d when the screen of FIG. 16 is displayed, the CPU 106 deletes the search phrase of the search editor 200 from the command based on the operation content, and also deletes the display data in the area 280. The display 107 is controlled. Thereafter, the process returns to step S1 to switch to the initial screen of FIG. 12, and a dictionary search process based on a new next search phrase can be performed.

  When the user selects and operates the full text tab 182 when the screen of FIG. 15 or 16 is displayed, the item receiving unit 254 receives the specified item “full text” from the operation content. The operated full-text tab 182 is highlighted, and the process proceeds to step S6.

  In step S6, the item receiving unit 254 outputs a command based on the received operation content. Based on the command from the item reception unit 254, the second output control unit 232 selects the designated item “of the headwords 152 (the headwords 152 displayed in the area 281 of FIG. 16) of the item searched in step S5. The associated headword 152 is selectively extracted from “full text”, and the extracted headword 152 is displayed in a list in the area 281 of the display 107 as shown in FIG. An explanatory text including the headword 152 selected by operating the cursor key 114D from the list of headwords 152 in the area 281 is displayed in the area 282 on the same screen.

  In the screen of FIG. 17, a dictionary name that is an identifier of the dictionary content 130 is displayed in a list in the area 201. The dictionary name in the area 201 indicates one or more dictionary names in which the entry words 152 displayed in the area 281 are stored.

  For example, when the user selects and designates the entry word 152 in the area 281, the output control unit 230 selectively highlights the dictionary name in which the designated entry word 152 is stored among the dictionary names in the area 281. As a result, the user can check the dictionary name in which the selected entry word 152 is stored. In FIG. 17, when “Ano Nagamasa [Asano Nagamasa]”, which is the headword 152 in the area 281, is designated, “Super Large Dictionary 3.0” in the area 201 is highlighted and the designated headline is displayed. It is notified that the word 152 has been registered (stored) in the “Super Large Dictionary 3.0”. In addition, the text of the item “explanatory text” read from the content 153 corresponding to the headword 152 read from “Super Great Dictionary 3.0” is displayed in area 282.

  If the user operates the clear key 113d when the screen of FIG. 17 is displayed, the screen is switched to FIG. 18 in step S7. In the screen of FIG. 18, the search phrase of the search editor 200 and the information in the area 280 are deleted. This informs the user that a search process using the input of a new search phrase is possible. In the screen of FIG. 17, in the search method selection tab 180, the full text tab 182 is highlighted, and the search target item specified immediately before (ie, the item specified in step S5) is “full text”. It is informed that it remains valid.

  When the screen of FIG. 17 is displayed, when the user performs an operation of selecting the tab 193 of the search character type selection tab 190 in order to change the character type of the search word / phrase in the search character type selection tab 190, the processing is performed in steps S8a or S8b. Move to one of the following. In the present embodiment, the process may move to either step S8a or S8b.

  When the process proceeds to step S8a, the operation of changing the character type is prohibited in a state where the search word / phrase is input to the search editor 200. In other words, the character type change process is invalidated to NOP (no operation). On the screen of FIG. 19, the CPU 106 outputs an alert such as displaying a message 286 notifying that the operation is not accepted. Therefore, it is possible to prevent the search term from being erased from the input search editor 200 by accidentally touching another character type tab by the user.

  On the other hand, when the process proceeds to step S8b, when the tab 193 is operated and the change to the character type “English” is designated, the search word / phrase in the search editor 200 is deleted, and the display 107 displays the area 280 from the screen of FIG. The screen is switched to the screen shown in FIG. In FIG. 20, regarding the search character type selection tab 190, the tab 193 is highlighted instead of the tab 191, so that the user can confirm that the change operation to the character type “English” is accepted.

(Timing for disabling tabs)
In the present embodiment, among the one or more types of search target items determined by the determination unit 221, the third output control unit 233 determines the item for which the related headword has not been searched by the item search unit 222. A tab indicating the type of item is output to the display 107 according to a predetermined invalid display mode (gray-out display). Regarding the timing of starting the grayout display, the following patterns A and B will be described in association with a mode in which a headword list as a search result is displayed in the region 280.

<Pattern A>
Referring to FIG. 21A, in the case of the search phrase “Toyoto Mihideyoshi”, when the user inputs the first character “to” to search editor 200 via operation unit 202, the phrase reception unit 251 accepts the one character of the search editor 200 as a search phrase. The item search unit 222 starts a dictionary search based on the received search term “to”, and a list of search results is displayed in the area 280. At this time, the third output control unit 233 grays out the phrase tab 184 corresponding to the item “sung phrase” that the determination unit 221 did not determine as the search target item. In addition, the number of headwords 152 read from the dictionary content 130 for each item is counted. For example, when the headword searched for “example sentence” is zero, the refinement search for “example sentence” is invalid. As shown, the example sentence tab 183 is switched to gray-out display.

  Thereafter, each time a subsequent character is input to the search editor 200, the item search unit 222 starts a dictionary search based on the character string of the search editor 200, and a list of search results is displayed in the area 280. The In this way, a search method in which search processing is performed every time a character is input to the search editor 200 and the list of search word entries 152 in the region 280 is updated is referred to as incremental search. When the incremental search of pattern A is performed, the third output control unit 233 displays the item “spoken phrase” that the determination unit 221 has not determined as the search target item when the search result list is displayed in the area 280. "Is displayed in gray out. When the number of headwords 152 read from the dictionary content 130 for each item becomes zero, the tab of the item in the search method selection tab 180 is switched to grayout display.

  When the character input of the search term “Toyo Tomi Hideyoshi” is completed in the search editor 200, as shown in FIG. 21B, the search result based on the search term “Toyo Tomi Hideyoshi” is displayed in the area 280. A list of headwords 152 is displayed.

<Pattern B>
In the pattern B, unlike the case of the incremental search of the pattern A, the search process is started when the character string of the search word is completed in the search editor 200 and the user operates the key 113b (see FIG. 22A). ). The command receiving unit 253 receives a search command from the operation content of the key 113b. The item search unit 222 collectively searches the plurality of dictionary contents 130 based on the search phrase (input character string of the search editor 200) input via the phrase reception unit 251 in accordance with the search command from the command reception unit 253. A list of headwords 152 as a result of the search is displayed in a list in an area 280 as shown in FIG. In addition, when inputting a search term with handwritten characters, recognition processing is performed after handwritten characters are input, a character string as a recognition result is input to the search editor 200, and the search processing is performed when the key 113b is operated. Be started.

  The third output control unit 233 causes the corresponding tab in the search method selection tab 180 to be grayed out when the first character “to” is input in the pattern A and when the key 113b is operated in the pattern B. That is, in any case, when the search editor 200 is blank, the search method selection tab is not grayed out, and the corresponding tab in the search method selection tab 180 is grayed out when the search result list is displayed. The As a result of the search, the user can check an item for which the headword 152 has not been searched while collating it with the headword 152 displayed in a list. Further, when a narrowing search is performed while referring to the headwords 152 displayed in a list, items that can be narrowed down can be quickly identified.

[Embodiment 2]
A modification of the first embodiment will be described. In this modification, a search is performed to further narrow down the headword 152 from the search result by the item search unit 222.

  For example, in the screen of FIG. 17, the fourth output control unit 234 determines the headword 152 included in the search result and the type of dictionary content (dictionary name) in which the headword 152 is stored by the determination unit 221. For each type of item to be searched (“full sentence”, “example sentence”, “sung phrase”), the display 107 is made to output.

  Specifically, when the user designates the full-text tab 182 corresponding to the item “full-text”, the fourth output control unit 234 displays the contents 153 of the dictionary content 130 among the headwords 152 listed in the area 281. Only the headword 152 read from [Explanation] is selected and displayed. Similarly, when the user performs an operation of designating the example sentence tab 183 corresponding to the item “example sentence”, the fourth output control unit 234 displays [example sentence of the content 153 of the dictionary content 130 among the entry words 152 displayed in the list in the area 281. ], Only the headword 152 read out is selected and displayed.

  As a result, it is possible to obtain a headword 152 in which the search word / phrase is described only in [descriptive text] or [example sentence] of the dictionary content 130 by narrowing search and present it to the user.

[Embodiment 3]
A modification of the first embodiment will be described. In this modification, a search is performed to further narrow down the headword 152 from the search result by the item search unit 222.

  First, the dictionary designation accepting unit 255 accepts a user operation that designates the type of the dictionary content 130 output to the area 201 of the display 107. The fifth output control unit 235 is, for example, the type of dictionary specified by the user operation received by the dictionary specification receiving unit 255 from the headwords 152 searched and displayed by the item search unit 222 of FIG. A headword 152 stored in the content 130 is selectively extracted and output to the display 107.

  For example, when the user designates “full-translated old word dictionary” in the area 201, the fifth output control unit 235 includes the dictionary content 130 whose dictionary name is “full-translated old word dictionary” among the headwords 152 listed in the area 281. Only the headword 152 read from is selected and displayed.

  As a result, it is possible to present the result of the narrowing search that selectively extracts only the headword 152 that describes the search word / phrase in the associated content 153 in the desired type of dictionary content 130.

[Embodiment 4]
In the first embodiment, the determination unit 221 determines one or more search target items from the table 300 based on the character type of the search phrase. However, the method for determining the search target item is not limited to this, and the character type of the search phrase The search target item may be changed according to the search word input method.

  FIG. 23 is a diagram showing an example of a table 300A for determining search target items according to the fourth embodiment. The table 300A shows items to be searched for corresponding to various combinations of the character type of the search phrase and the input method of the search phrase specified by the search character type selection tab 190. The search phrase input method includes key input on the keyboard 114, handwritten input from the input pad, input by operating the 50-sound table, and input by operating the QWERTY which is an alphabetic array key.

  According to the table 300A, when a search term is input with a set of character types “Japanese” and “key input”, the search target items are “collective”, “full text”, and “example sentence”. In addition, when a search term is input in a set of character types “Chinese” and “handwritten input”, it is indicated that the search target item is “collective” only. Further, according to the table 300, when the character type is “Japanese”, “Kanji conversion”, and “English” and the input method is “key input”, the “collective” search is performed as shown in FIG. This is performed according to the A> incremental search. The search by the other group is performed according to a method that is not the incremental search of <pattern B> shown in FIG.

  Therefore, the determination unit 221 can also determine a search target item from the table 300A, and the item search unit 222 can determine from the table 300A whether the search should be performed by an incremental search.

  Note that the electronic dictionary device 100 arbitrarily designates which of the tables 300 and 300A is to be referred to by an external operation.

(Specific search process)
The search processing according to the present embodiment will be described with reference to display screen examples in FIGS. The display screen transitions according to the user operation based on the character type of the search phrase, the search target item, and the character input state of the search phrase to the search editor 200.

  With reference to FIG. 24, the case of <pattern A> of the incremental search will be described. For example, when the search term is keyed and the character type “Japanese” and the search target item “collective” are designated (step S10), the screen of FIG. 24A is displayed. When the user does not input a character in the search editor 200 and the user key-inputs the first character “to” of the search term “Toyoto Hidehide”, the item search unit 222 is based on the input character “to”. An incremental search by dictionary search (batch search) is performed, and a list of headwords 152 as a result of the search is displayed on the display 107 as shown in FIG. 24B (step S11). At this time, the phrase tab 184 is grayed out to notify that it is invalid.

  In step S12, when the key input for the search term “Toyo Tomi Hideyoshi” is completed, the search results of the incremental search are displayed in a list (see FIG. 24C). In FIG. 24C, based on the search result, the third output control unit 233 detects the item “example sentence” in which the related headword has not been searched from the search result, and displays the corresponding example sentence tab 183 in gray out. . Also, the phrase tab 184 corresponding to the item “sung phrase” that is not determined as the search target item by the determination unit 221 is grayed out.

  If the user desires to switch from key input to handwriting input on the screen of FIG. 24A in step S10 and operates the tab 211, the process proceeds to step S13, and the screen is switched to FIG. 25A. Change.

  In step S <b> 13, the CPU 106 sets an input pad in the area 280 according to the operation content of the tab 211. In step S14, when the user starts handwriting input for inputting a search word to the input pad using the stylus pen 110 and completes the input of the handwritten character “Hideyoshi Toyotomi”, the user operates the button 284. In step S15, the word A search phrase that is a result of pattern recognition processing by the receiving unit 251 is input to the search editor 200 as shown in FIG.

  In step S15, when the user operates the button 285 in FIG. 25C, the command receiving unit 253 receives a search command from the operation content. In step S <b> 16, the item search unit 222 performs a collective search process (that is, a method that is not an incremental search) based on the search term “Hideyoshi Toyotomi” based on the search command. In FIG. 25D, a list of headwords 152 as a result of the search is displayed. Further, the third output control unit 233 detects an item “example sentence” in which the related headword 152 is not searched from the search result, and displays the corresponding example sentence tab 183 in gray. Also, the phrase tab 184 corresponding to the item “sung phrase” that is not determined as the search target item by the determination unit 221 is grayed out.

  If the user operates the clear key 113d on the screen of FIG. 25D in step S16, the process proceeds to step S13, the screen is switched to FIG. 25A, and a new search phrase can be input by handwriting. It becomes.

  When the user operates the clear key 113d on the screen of FIG. 25D in step S16, the screen is switched to the screen for handwriting input of FIG. If the user operates the full text tab 182 corresponding to the item “full text” that is not grayed out on the screen in FIG. 25D, that is, the operation reception is valid, the screen in FIG. 26A is displayed in step S17. Is displayed.

  In the search processing of the item search unit 222 by operating the button 285 in step S15, search processing is performed for one or more types of items (“collective”, “full text”, “example sentence”) determined by the determination unit 221 from the table 300A. The search result of each item is stored in the area of the main storage unit 103.

  26A, when the full text tab 182 corresponding to the item “full text” is operated, the output control unit 230 reads the search result corresponding to the item “full text” from the main storage unit 103, It is displayed on the display 107. Thus, the list of headwords 152 as a result of the batch search in FIG. 25D is switched to the list of headwords 152 as a result of the full-text search in FIG. Similarly, when the collective tab 181 is operated on the screen of FIG. 26A, the output control unit 230 reads the search result corresponding to the item “collective” from the main storage unit 103, as shown in FIG. Is displayed on the display 107. In this way, the search result can be switched and displayed by operating the tab of the search method selection tab 180.

  If the user operates the clear key 113d during the screen display of FIG. 26A in step S17, the screen is switched to the screen of FIG. 26B in step S18. In addition, when the character “A” is input to the search editor 200 on the screen of FIG. 26A in step S17 and the key 113b is operated, the process proceeds to step S19, and in step S19, the display 107 is displayed. The screen of FIG. 26A is switched to the screen of FIG. In addition, on the screen of FIG. 26C, a message “not applicable” is displayed as a result of the dictionary search based on the search term “Hideyoshi Toyotomi” by the search unit, indicating that the corresponding entry word 152 has not been searched. If the user operates the clear key 113d when the screen of FIG. 26C is displayed, the process proceeds to step S18. In step S18, the screen of the display 107 is switched from the screen of FIG. 26C to the screen of FIG.

  As shown in steps S17 and S19, by inputting a character after the search term after the search processing of the search editor 200, the search processing is performed with the search term composed of the original search term and the input character. Can be made.

[Embodiment 5]
In the fifth embodiment, a search process when the character type “English” is designated will be described with reference to FIGS. FIG. 27 shows an example of a display screen in a state where the character type “English” and the search target item “collective” are specified and no characters are input to the search editor 200. A case where the user operates the keyboard 114 to input the search phrase “apple” into the search editor 200 when the screen of FIG. 27 is displayed will be described with reference to FIG.

  In FIG. 28, for ease of explanation, search processing conditions are shown instead of the screen display example. First, in step ST1, when the item search unit 222 performs a search process using the character type “English”, the search target item “collective”, and the search term “apple”, a list of headwords 152 as a search result is displayed. . When the example sentence tab 183 is selected on the search method selection tab 180 when the list is displayed, a list of head words 152 whose “example sentence” is the search result is displayed in step ST3. When the collective tab 181 is selected in the state of step ST3, the display returns to step ST1. Further, when the collective tab 181 is selected in step ST1, the display is switched to the display of step ST2, and a list display of “full text” search is performed. When the full text tab 182 is selected and operated in step ST2, the display is switched to the display of step ST1. .

  Similarly, switching between the steps ST2 and ST3 is performed according to the selection operation of the example sentence tab 183 or the full sentence tab 182.

  When the character type “English” is designated, the search target item determined by the determination unit 221 includes “sung”. Therefore, in step ST4 of FIG. 28, the item search unit 222 performs a search process with the character type “English”, the search target item “sung phrase”, and the search phrase “apple”, and associates it with “sung phrase” including the search phrase “apple”. A list of the entered headwords 152 is displayed. Similarly, between step ST4 and other steps ST1, ST2, and ST3, the list of displayed headwords 152 is displayed by switching the search method selection tab 180 to change the state between them. Can be switched to the list of headwords 152 corresponding to the item of the selected tab.

  FIG. 29 and FIG. 30 show display examples when searching based on the search term “have to”, in particular, FIG. 29 shows the result of the search for the item “example sentence”, and FIG. 30 shows the item “sung phrase”. The result of the search is shown.

  In the case of the character type “English”, according to the table 300 (or 300A), it is possible to search for all items of “collective”, “full sentence”, “example sentence”, and “sung phrase”. "Can be searched by using two or more search terms that are separated by a blank and entered in the search editor 200. Therefore, when transitioning to “batch” where only one word can be entered, “have to” is converted to “haveto” and a search is executed.

[Embodiment 6]
FIG. 31 and FIG. 32 show the state transition of the search processing screen due to the change between character types. In the “Examine” screen, the search target items can be made common to “collective”, and the character type can be changed in a state where no characters are input in the search editor 200, that is, in a state where no search word is input.

  FIG. 31A shows a screen in which the tab 191 of the character type “Japanese” is selected, and FIG. 31B shows a screen in which the tab 193 of the character type “English” is selected. Shows a handwriting input screen in which the tab 194 of the character type “Chinese” is selected, and FIG. 31D shows a screen in which the tab 195 of the character type “Pinyin” is selected. The screen on which the tab 192 of the character type “character for Kana-Kanji conversion” is selected is the same as that in FIG. By operating the character type selection tab of the search character type selection tab 190 between these screens, it is possible to switch from the original screen to the character type screen of the operated tab. When the input method is switched to QWERTY on the Pinyin screen of FIG. 31D, the screen of FIG. 32 is displayed. In the screen of FIG. 32, a QWERTY software keyboard screen is displayed in association with the input pad in the area 280.

  When the handwritten character “A” is input on the Chinese handwriting input screen of FIG. 31C, the character is recognized and “A” is set in the search editor 200, the batch search based on the search term “A” The headword 152 as a result of the search is displayed as a list. At this time, when the character type “Pinyin” is selected and operated, the search screen for the character type “Pinyin” in FIG. 31D is switched and displayed. In addition, in the Pinyin screen of FIG. 31D, when the character “a” is input by key input and a collective search based on the search term “a” is performed, a headword 152 as a search result is displayed in a list. At this time, when the character type “Chinese” is selected and operated, the search screen for the character type “Chinese” in FIG. It is also possible to switch from the Pinyin screen of FIG. 31D to the screen of FIG. 32 and input the search phrase “a” from the QWERTY software keyboard instead of the key input of the keyboard 114.

  Pinyin and Chinese are highly related to each other because Chinese is expressed in Chinese characters, and Pinyin shows the reading (sound) of Chinese characters.
