[0022] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1 This is a functional block diagram showing the configuration of an electronic circuit of an information processing device according to an embodiment of the present invention.

[0024] In this embodiment, an example is shown in which the information processing device is configured as, for example, the electronic dictionary 10. In addition, the information processing device can be realized by various electronic devices such as a personal computer, a smartphone, and a tablet PC in addition to the electronic dictionary 10.

[0025] The electronic dictionary 10 is a device that can read out the data of a dictionary or a lexicon by inputting an entry or selecting an item, and can display or reproduce various information. The dictionary data stored in the electronic dictionary 10 includes at least one semantically related information corresponding to a plurality of words as entries. The semantically related information includes text information. The dictionary data includes, for example, English-based dictionaries, Mandarin-based dictionaries, encyclopedic dictionaries, etc. As English-based dictionaries, for example, there are Japanese-English dictionaries, English-Japanese dictionaries, English-English dictionaries, English synonym dictionaries, etc., which sometimes include multiple different dictionaries. Similarly, as Mandarin-based dictionaries, there are Mandarin dictionaries, synonym dictionaries, antonym dictionaries, archaic dictionaries, etc., which sometimes include multiple different dictionaries.

[0026] The electronic dictionary 10 also stores content information data including various content information (content) of texts such as literary works and reference manuals.

[0027] The electronic dictionary 10 has a computer configuration that reads a program recorded in various recording media or a program transferred thereto and controls its operation according to the read program. The electronic circuit includes a CPU (central processing unit) 11 .

[0028] The CPU 11 functions as a control unit that controls the entire electronic dictionary 10. The CPU 11 controls the operation of each circuit unit according to a control program pre-stored in the memory 12, or according to a control program read into the memory 12 from a recording medium 13 such as a ROM card via a recording medium reading unit 14, or according to a control program downloaded from a server 20 via a network N including the Internet and read into the memory 12 via a communication unit 15.

[0029] The control program stored in the memory 12 is activated based on an input signal corresponding to a user operation from the key input unit 16, an input signal corresponding to a user operation from the touch panel 17, or a communication signal with a server 20 on an externally connected network N, or a connection communication signal with a recording medium 13 such as an EEPROM (registered trademark), RAM, ROM, etc. connected via the recording medium reading unit 14.

[0030] The CPU 11 is connected to a memory 12 , a recording medium reading unit 14 , a communication unit 15 , a key input unit 16 , a touch panel 17 , and the like.

[0031] As control programs stored in the memory 12, there are stored: a system program that manages the operation of the entire electronic dictionary 10, and a communication program for data communication with a server 20 on an externally connected network N, a personal computer, and other electronic devices. In addition, the memory 12 stores a dictionary control program 12a, which performs a search function for searching information corresponding to input data from dictionary data or content information data and outputs it. Based on the dictionary control program 12a, the CPU 11 displays the first main screen displaying information such as text retrieved by the search function in a first area secured in the display surface of the touch panel 17 (display). The first area is secured, for example, as the entire display surface of the touch panel 17.

[0032] In addition, the dictionary control program 12a includes a small dictionary function program 12b for executing a small dictionary function that performs a simple search for a character string (word, etc.) selected by a user operation from the text displayed on the touch panel 17. Based on the small dictionary function program 12b, when a character string (word) in the text displayed on the first main screen is specified by a user operation, the CPU 11 causes a sub-screen displaying information (first information) such as text retrieved by the small dictionary function related to the specified word to be displayed on the second area of ​​the touch panel 17 (display screen).

[0033] In the electronic dictionary 10 of the present embodiment, whenever a word is specified from the text displayed on the first main screen through user operation, a sub-screen displaying the first information related to the specified word can be additionally displayed in the second area of ​​the display screen, and multiple sub-screens (mini dictionary screens) can be displayed simultaneously in the second area.

[0034] Furthermore, when a plurality of sub-screens are displayed in the second area, when the user performs an instruction operation on any of the sub-screens, a process determined based on the word designated when the instruction operation was performed is displayed, such as a term search (term jump), an example search (example jump), or an idiom search (idiom jump) based on the corresponding word as an entry and in a plurality of different dictionaries, can be performed, and a second main screen displaying the second information as the search result is displayed in the first area instead of the first main screen. In addition, the process determined based on the designated word is not limited to the retrieval process, and various processes such as outputting a voice related to the word and adding a mark to the word displayed on the first main screen can be adopted.

[0035] In addition, the memory 12 stores dictionary data 12c, setting data 12d, content information data 12e, small dictionary screen management data 12f, and the like.

[0036] The dictionary data 12c includes a database including a plurality of dictionaries such as English-Japanese dictionary, Japanese-English dictionary, English-English dictionary, Mandarin dictionary, synonym dictionary, antonym dictionary, and archaic dictionary. The dictionary data 12c includes information such as text corresponding to each entry or item for each dictionary.

[0037] The dictionary data 12c includes small dictionary data 12c1 used in the simple search process performed by the small dictionary function. In the small dictionary data 12c1, the text and other information corresponding to each entry or item are included for each dictionary / lexicon, similarly to the dictionary data 12c, but the amount of information is less than that of the dictionary data 12c in order to be displayed on a narrow display screen. The small dictionary data 12c1 may be dedicated data for the small dictionary function, or may be data obtained by extracting a part of the dictionary data 12c, or may be a mixture of the two.

[0038] The setting data 12d is data set according to user operations and used to control the operation of the electronic dictionary 10. The setting data 12d is set / updated by receiving user operations through the setting screen in the setting function executed by the CPU 11. In addition to hardware-related control data such as the brightness of the screen of the touch panel 17, the setting data 12d also includes program-related control data such as the mini-dictionary function. The setting data related to the mini-dictionary function includes, for example, data related to the display control of the sub-screen that displays information such as text retrieved by the mini-dictionary function (see Fig.15 ).

[0039] The content information data 12e is data of various content information such as literature works and reference manuals, and includes data of images (still images and moving images), voice, etc. in addition to text.

[0040] In addition, the dictionary data 12c and content information data 12e may not be built into the main body of the electronic dictionary 10, but may be obtained from a database (e.g., server 20) accessible via the network N, or may be read from a pluggable recording medium 13 by the recording medium reader 14.

[0041] The small dictionary screen management data 12f is data for managing the sub-screens displayed by the small dictionary function. The small dictionary screen management data 12f includes, for example, data for identifying the sub-screen displayed in the second area, data indicating whether to maintain the display (whether to perform a hold setting) when a new sub-screen is added to the second area for each of the plurality of sub-screens displayed in the second area, data indicating the display position of the sub-screen in the second area, data indicating the order in which the sub-screens are set to be held, and the like.

[0042] Figure 2It is a front view showing the external structure of the electronic dictionary 10 .

[0043] exist Figure 2 In the case of the electronic dictionary 10, a CPU 11, a memory 12, a recording medium reading unit 14, a communication unit 15, a key input unit 16 and a pen storage unit 18a are built in the lower side of the device body that is opened and closed, and a touch panel 17 is provided on the upper side of the device body.

[0044] The key input unit 16 includes character input keys 16a, dictionary selection keys 16b for selecting various dictionaries or various functions, an enter key 16c, a return key 16d, cursor keys (up, down, left, and right keys) 16e, a power button, and other various function keys.

[0045] The touch panel 17 is composed of a display such as an LCD (Liquid Crystal Display) and a touch pad (position input device) in combination. In addition to the button 17a that is always displayed, the touch panel 17 displays various menus and buttons corresponding to the execution of various functions, various information such as text and images, etc.

[0046] The electronic dictionary 10 can input a user's instruction by the user's operation on the key input unit 16 or a touch operation (performed by the tip of the pen 18 or a fingertip) on a menu or button displayed on the touch panel 17 .

[0047] The audio output unit 19 includes a speaker, etc., and outputs audio of words or content information, etc. In addition, the audio output unit 19 can also include an audio signal output terminal, and output audio through headphones, etc. connected to the audio signal output terminal.

[0048] In the electronic dictionary 10 configured in this way, the CPU 11 controls the operation of each circuit unit according to the instructions described in the dictionary control program 12 a , and the software and hardware operate in coordination to realize the functions described in the following operation description.

[0049] Next, the operation of the electronic dictionary 10 according to the present embodiment will be described.

[0050] Figure 3 , Figure 4 , Figure 5 This is a flowchart for explaining the operation of the electronic dictionary 10 according to the present embodiment.

[0051] When the power is turned on, the CPU 11 starts the dictionary control program 12a and starts the dictionary control process. The CPU 11 causes the touch panel 17 to display the main screen as the initial screen. The main screen includes a menu for selecting a dictionary / thesaurus (hereinafter described only as a dictionary) as a search object. In the menu, a dictionary as a search object can be selected. For example, with respect to the dictionary as the search object, it is possible to select all dictionaries as the search object, a dictionary of a specific range (for example, an English dictionary, etc.), or a specific dictionary (for example, ○○ English-Japanese dictionary, etc.).

[0052] When a dictionary as a search target is selected in the menu, CPU 11 displays an initial search screen having an input area for inputting a search target character string (search word) on touch panel 17. The search screen includes an input area for inputting a search character string, a search start button for instructing execution of a search process, and the like.

[0053] When a character string (word) as a search term is input by operating the character input key 16a or by handwriting character input using the pen 18, the CPU 11 displays the input character string in the input area. Here, when the execution of the search is instructed by operating the confirmation key 16c or the search start button, the CPU 11 performs a search process on the dictionary data as the search target dictionary based on the character string (search character string) of the search term input in the dictionary search screen. That is, the CPU 11 searches for entries (words) containing the search term (search character string) from the dictionary data 12c.

[0054] CPU 11 displays a word list screen showing a word list including at least one entry (word) retrieved from dictionary data 12c on touch panel 17. When the entry at which the cursor is located is changed by moving the cursor in the word list, CPU 11 changes semantic information according to the changed entry and displays it in the information display area.

[0055] When the word list screen is displayed, the entry at the cursor position is selected by operating the confirmation key 16c, or the entry displayed in the word list is designated by the pen 18 to select a word, the CPU 11 selects the entry displayed at the cursor position as the target word. The CPU 11 retrieves the semantic information including the text corresponding to the entry selected as the target word from the dictionary data 12c, and displays a detailed screen (first main screen), for example, the semantic information in the form of text, in the first area reserved on the display surface, instead of the word list screen displayed on the touch panel 17 (step A1).

[0056] Figure 6 1 is a diagram showing an example of a detail screen (first main screen) D1 displayed on the touch panel 17 . Figure 6 The detailed screen D1 shown shows the semantic information in the form of text recorded in the dictionary data 12c corresponding to the selected entry. Here, the information related to the entry "about" is shown when the entry "about" is selected from the word list of the word list screen. Figure 6 An example is shown in FIG.

[0057] When a swipe operation (drag operation) is performed in the up and down directions on the touch panel 17 using the pen 18, or a cursor operation is performed using the cursor key 16e (up and down keys) while the detailed screen D1 is displayed (step A2, up and down swipe), the CPU 11 scrolls the semantic information including the text displayed on the detailed screen D1 (step A3).

[0058] When a slide operation is performed in the left-right direction on the touch panel 17 using the pen 18 while the detailed screen D1 is displayed (step A2 , left-right slide), the CPU 11 selects the text (word) displayed at the position specified by the slide operation as a new target word (step A4 ).

[0059] Based on the target word designated by the slide operation, the CPU 11 searches the small dictionary data 12c1 for semantic information corresponding to the target word by using the small dictionary function (step A11).

[0060] Here, the CPU 11 determines whether or not a small dictionary search screen (sub screen) for displaying search results obtained by the small dictionary function is already displayed on the display screen of the touch panel 17 based on the small dictionary screen management data 12 f.

[0061] When the small dictionary search screen (sub-screen) is not already displayed (step A12, "No"), CPU 11 causes a new small dictionary search screen (sub-screen) to be added to the detail screen D1 of the touch panel 17, and causes the information retrieved from the small dictionary data 12c1 to be displayed on the small dictionary search screen (step A13).

[0062] Figure 7 1 is a diagram showing an example of a screen after a small dictionary screen D3 (sub screen) is additionally displayed in the second area of ​​the touch panel 17 . Figure 7 The screen shown shows an example in which a target word AR21 ("surprisingly" which is different from the word list selected) is specified from the text displayed on the original detailed screen D1. The target word AR21 selected in the detailed screen D1 is, for example, marked (colored background) and displayed so as to be easily recognizable from the text in the detailed screen D1.

[0063] Figure 7 The screen shown is a screen in which a small dictionary screen D3 is additionally displayed in the second area reserved at the lower edge of the original detailed screen D1. Therefore, the original detailed screen D1 is changed to a detailed screen D2 with a reduced display area. The CPU 11 sets data on the added small dictionary screen D3 in the small dictionary screen management data 12f. In the small dictionary screen management data 12f, data indicating that the added small dictionary screen D3 is not to be retained as an initial setting is set.

[0064] In addition, Figure 7 In the example shown, since the information retrieved from the small dictionary data 12c1 is English text, the range of semantic information that can be browsed is enlarged by setting the small dictionary screen D3 to a horizontally long shape and displaying it at the lower end of the detailed screen D2. Therefore, for example, in the case of displaying a text written vertically, the small dictionary screen D3 can also be set to a vertically long shape and additionally displayed on the left or right side of the detailed screen D2. In addition, the small dictionary screen D3 can also be additionally displayed as a sub-screen in other forms.

[0065] exist Figure 7 The illustrated small dictionary screen D3 includes a text area D31 for displaying semantic information (text) and a plurality of operation buttons for user instruction operations (eg, touch operations). The operation buttons are displayed as symbols, icons, characters, etc. indicating the corresponding processing.

[0066] In the small dictionary screen D3, for example, a plurality of operation buttons including an entry jump button B31, an example jump button B32, an idiom jump button B33, a voice button B34, and a mark button B35 are arranged and displayed in a horizontal direction at a position adjacent to the text area D31. The operation buttons B31 to B35 are buttons for executing a predetermined process for a word (here, the target word AR21) designated when the small dictionary screen D3 (sub-screen) on which the instruction operation is performed is displayed as an object when the user performs an instruction operation. By executing the process corresponding to the instruction operation on the operation buttons B31 to B35, a second main screen is displayed in the first area of ​​the touch panel 17 instead of the original detailed screen D1 (first main screen), and the second main screen displays the first detailed information which is different from the first information displayed in the text area D31 of the small dictionary screen D3 and has a larger amount of information than the first information.

[0067] The entry jump button B31, the example jump button B32, and the idiom jump button B33 are buttons for executing a search with the target word as the search term for multiple dictionaries (second dictionary data) different from the dictionary (first dictionary data) for searching the first information displayed in the text area D31, and for instructing a process of transferring (jumping) to a screen displaying the search results. In addition, the second dictionary data may also include the first dictionary data. The entry jump button B31 is a button for instructing the execution of a search process with the entries of multiple dictionaries as the object. The example jump button B32 is a button for instructing the execution of a search process with the example sentences of multiple dictionaries as the object, and the idiom jump button B33 is a button for instructing the execution of a search process with the idioms of multiple dictionaries as the object.

[0068] The speech button B34 is a button for instructing the output of the speech of the word to be read aloud. The mark button B35 is a button for displaying (marking) the background of the character string selected in the detail screen D2 in a specific color.

[0069] By providing a plurality of operation buttons on the mini-dictionary screen D3, various processes defined corresponding to the operation buttons can be executed by simple operations from the mini-dictionary screen D3 for the character string (word) selected on the detailed screen D1.

[0070] The mini-dictionary screen D3 further displays a close button B36 and a hold button B37.

[0071] The close button B36 is a button for closing (erasing) the mini-dictionary screen D3 and returning to the original display state in which the detailed screen D1 is displayed.

[0072] The hold button B37 is a button for instructing to hold the display state of the small dictionary screen D3. By selecting the hold button B37, data indicating that the hold setting is made for the small dictionary screen D3 is set in the small dictionary screen management data 12f. By holding the small dictionary screen, it is possible to prevent the small dictionary screen from being erased when a target word is reselected from the text displayed on the detailed screen D2 and a new small dictionary screen is displayed.

[0073] When the operation buttons B31 to B35 are designated by, for example, a touch operation using the pen 18 (step A14 , Yes), the CPU 11 executes the processing defined in correspondence with each operation button as described above (step A15 ).

[0074] For example, when entry jump button B31 is operated, CPU 11 performs search processing for entries of multiple dictionaries based on target word AR21 and displays information as search results in the first area of ​​touch panel 17 instead of the screen displaying original detail screen D2 and mini dictionary screen D3.

[0075] In this way, by operating the operation button provided on the mini-dictionary screen, search processing for a plurality of dictionaries is executed and the search results are displayed on the touch panel 17 , so that efficient dictionary search utilizing the mini-dictionary function can be performed.

[0076] In addition, the detailed description of the processing when the example sentence jump button B32, the idiom jump button B33, the voice button B34, and the mark button B35 are operated is omitted. After executing the processing corresponding to the instruction operation on the operation buttons B31 to B35 and transferring to the screen corresponding to the processing result, the CPU 11 will execute other processing corresponding to the instruction operation input in the transfer target screen, and the description of the subsequent processing is omitted.

[0077] When the hold button B37 is selected (step A16 , YES), the CPU 11 sets data indicating that the hold setting is performed on the small dictionary screen D3 in the small dictionary screen management data 12 f (step A17 ). Figure 8 1 and 2 are diagrams showing an example in which the hold button B37 of the mini-dictionary screen D3 is selected by the pen 18 .

[0078] When the close button B36 is selected, the CPU 11 erases the small dictionary screen D3 from the display surface (second area) of the touch panel 17 and deletes the data related to the small dictionary screen D3 in the small dictionary screen management data 12f (cancels the hold setting) (step A19).

[0079] Furthermore, when an operation other than the operation on the small dictionary screen D3 is performed (step A20, "Yes"), the CPU 11 refers to the small dictionary screen management data 12f and deletes the small dictionary screen that is not set to be kept. That is, when the small dictionary screen D3 is not set to be kept, when it is detected that an operation (for example, a sliding operation for scrolling the screen, etc.) is performed on the detailed screen D2 by the pen 18, the CPU 11 deletes the small dictionary screen D3 and deletes the data related to the small dictionary screen D3 in the small dictionary screen management data 12f (step A21).

[0080] On the other hand, when the small dictionary screen D3 is set to be kept, even if an operation different from the operation on the small dictionary screen D3 is performed, the CPU 11 keeps the small dictionary screen D3 displayed.

[0081] Thus, for example, it is possible to perform other processing such as changing the display content of the detailed screen by scrolling, etc. while maintaining the information of the unknown word selected from the detailed screen D1 displayed on the small dictionary screen D3. Therefore, it is not necessary to select a word again and redisplay the small dictionary screen D3 after performing other processing different from button operation such as changing the display content of the detailed screen, thereby improving operability.

[0082] In the present embodiment, by performing the hold setting on the small dictionary screen D3 , it is possible to browse the display contents (text) and the like displayed on the detail screen while always referring to the information displayed on the small dictionary screen D3 .

[0083] Next, a description will be given of a case where the small dictionary search screen (sub screen) is already displayed when a target word is selected in the detail screen D1.

[0084] For example, suppose in Figure 8 In the state shown in which the mini-dictionary screen D3 is set to be kept, a left-right sliding operation is performed to select a word from the text of the detailed screen D1, which is different from the operation on the mini-dictionary screen D3 (step A20, Yes). In this case, the mini-dictionary screen D3 is not deleted.

[0085] The CPU 11 selects the text (word) displayed at the position designated by the slide operation as a new target word (step A4 ), and searches for semantic information from the small dictionary data 12 c 1 based on the target word (step A11 ).

[0086] Here, when the small dictionary search screen (sub-screen) is already displayed (step A12, "Yes"), the CPU 11 determines whether the additional display of the small dictionary screen exceeds the preset upper limit number of small dictionary screens that can be displayed simultaneously. The upper limit number of small dictionary screens that can be displayed simultaneously is, for example, preset in the setting data 12d (the details will be described later). Fig.15 ).

[0087] When the upper limit of the displayable number is not exceeded (step A31 , No), CPU 11 displays the mini dictionary screen (sub screen) corresponding to the newly selected target word additionally in the second area of ​​the display surface of touch panel 17 (step A33 ).

[0088] Fig. 9This is a diagram showing an example of a screen in which a small dictionary screen (sub screen) is additionally displayed in the second area of ​​touch panel 17 . Fig. 9 The screen shown shows an example in which target word AR22 ("modest") is further specified from the text displayed on detail screen D2 independently of target word AR21. When multiple target words are selected from the detail screen, each target word may be displayed with a different color mark for easy identification.

[0089] exist Fig. 9 In the illustrated screen, a small dictionary screen D3s corresponding to the target word AR21 and a small dictionary screen D4s corresponding to the target word AR22 are displayed in a second area reserved at the lower side of the detailed screen D2.

[0090] Fig. 9 The mini dictionary screen D3s shown corresponds to Figure 7 The small dictionary screen D3 shown in the figure is changed to a reduced form in which the example sentence jump button B32, the idiom jump button B33, the pronunciation button B34, and the mark button B35 are omitted. When the CPU 11 displays a new small dictionary screen additionally, in order to suppress the amount of text displayed on the detailed screen D2 from being reduced due to the additional display of the small dictionary screen, the display form is changed so that the display size of the small dictionary screen that has been displayed and is being additionally displayed becomes smaller.

[0091] exist Fig. 9 In the example shown, the number of operation buttons displayed on each of the plurality of small dictionary screens D3s and D4s is less than Figure 7 In the case where one small dictionary screen is displayed as shown, the display size of the small dictionary screen is reduced. Thus, two small dictionary screens D3s and D4s can be horizontally arranged and displayed in the second area of ​​the touch panel 17.

[0092] In addition, the method of changing the display format is not limited to Fig. 9 For example, in Fig. 9 In the embodiment, only the entry jump button B31 is displayed, but other operation buttons can also be displayed, and multiple operation buttons can also be displayed. In addition, the display size of the small dictionary screen can be reduced by changing the form of the operation button (for example, reducing the size), reducing the size of the text area, etc.

[0093] The small dictionary screen D3s includes a text area D31, an entry jump button B31, and a close button B36. The small dictionary screen D4s includes a text area D41, an entry jump button B41, and a hold button B47. In the following description, it is assumed that the operation buttons with the same name provided on each small dictionary screen are buttons for executing the same processing.

[0094] Regarding the small dictionary screen D3s, the hold setting for the small dictionary screen D3 is maintained. Therefore, in order to be able to delete the small dictionary screen D3s by the instruction operation performed by the user, a close button B36 is provided. Regarding the small dictionary screen D4s that is additionally displayed, data indicating that it is not set to be held is set as an initial setting in the small dictionary screen management data 12f. Therefore, in order to be able to hold the small dictionary screen D4s by the instruction operation performed by the user, a hold button B47 is provided. The instruction operation for each button of the small dictionary screens D3s and D4s where the operation button is omitted will be described later.

[0095] Assume that, in the state where a plurality of small dictionary screens D3s and D4s are displayed, a left-right sliding operation is performed to select a word from the text of the detailed screen D2, which is different from the instruction operation for the small dictionary screens D3s and D4s (step A51, "Yes"). Here, if the small dictionary screen D4s is not set to be kept, the small dictionary screen D4s is deleted (step A52). On the other hand, if the small dictionary screens D3s and D4s are set to be kept, the small dictionary screens D3s and D4s are not deleted but remain displayed.

[0096] In this case, similarly to the above, the CPU 11 retrieves semantic information from the small dictionary data 12c1 based on the new target word, and displays additional small dictionary screens corresponding to the new target word in a manner that does not exceed the upper limit number of small dictionary screens that can be displayed simultaneously. Here, it is assumed that the upper limit number of small dictionary screens that can be displayed is set to "4".

[0097] Fig.10 1 is a diagram showing an example of a screen after a new small dictionary screen (sub screen) is additionally displayed in the second area of ​​touch panel 17 . Fig.10 The screen shown shows an example in which, for example, a target word AR23 ("expedition") is further specified from the text displayed on the detailed screen D2.

[0098] Fig.10The screen shown is a screen in which the second area reserved at the bottom of the detail screen D2 is enlarged, and a small dictionary screen D5s corresponding to the target word AR23 is additionally displayed at the bottom of the small dictionary screens D3s and D4s that have already been displayed. In the small dictionary screen D5s, as in the aforementioned small dictionary screen D4s, a text area D51, an entry jump button B51, and a hold button B57 are provided.

[0099] Next, instruction operations on the buttons of the mini-dictionary screens D3s, D4s, and D5s on which the operation buttons are omitted will be described.

[0100] The mini-dictionary screens D3s, D4s, and D5s temporarily display the omitted operation buttons by performing a predetermined operation on the respective display areas. In the present embodiment, for example, the omitted operation buttons are displayed by performing a predetermined operation such as a slide operation on a single entry jump button.

[0101] For example, when CPU 11 detects that the entry jump button B51 of the small dictionary screen D5s is slid using the pen 18 (or fingertip) (step A34, "Yes"), it displays the example jump button B52, idiom jump button B53, voice button B54, and mark button B55 that were omitted from display.

[0102] Fig.11 FIG. 2 is a diagram showing a display example in which the operation buttons B52 to B55 are omitted. Fig.11 In the example shown, by touching the entry jump button B51 with the pen 18 and sliding it in the left direction (the direction where the text area D51 is displayed), operation buttons B52 to B55 are displayed in the direction of the sliding operation. Figure 8 The plurality of operation buttons B52 to B55 are displayed in the same arrangement as in the case of displaying one mini dictionary screen shown in the figure. Thus, the operability of the temporarily displayed operation button can be made the same as the operability of one operation button displayed on the mini dictionary screen.

[0103] Furthermore, in the above description, the omitted operation button is displayed by a sliding operation, but other indication operations such as a double-click operation and a long-press operation may also be adopted. In addition, not only a sliding operation starting from the display position of the entry jump button but also a prescribed operation starting from other positions may be adopted. In addition, the display of the entry jump button may also be omitted, and other buttons (symbols, icons, signs, text, etc.) for indicating the display of the operation button may be displayed instead, and the omitted multiple operation buttons may be displayed according to the selection operation for the button.

[0104] When the operation buttons B52 to B55 are designated by, for example, a touch operation using the pen 18 (step A44 , YES), the CPU 11 executes the processing defined in correspondence with each operation button as described above (step A45 ).

[0105] In this way, when multiple small dictionary screens D3s, D4s, and D5s corresponding to multiple selected words displayed on one screen are displayed simultaneously, various processes (jump processing (entries, examples, idioms), voice output, mark adding, etc.) for words set to display each small dictionary screen can be performed with good operability without significantly impairing convenience compared to the case where one small dictionary screen is displayed.

[0106] In addition, since the display of the entry jump button for the small dictionary screens D3s, D4s, and D5s is not omitted, the processing of executing the entry jump can be instructed by performing a touch operation with the pen 18. Similarly, when the selection operation of the close button or the hold button for the small dictionary screens D3s, D4s, and D5s is detected (steps A46, A48, "Yes"), the CPU 11 performs the processing corresponding to the selection operation of the close button or the hold button for the small dictionary screen on which the button is displayed (steps A47, A49). In addition, the content of the processing is assumed to be executed in the same manner as described above, and the description thereof is omitted.

[0107] When an operation other than the operation on the small dictionary screen is performed (step A51, "Yes"), the CPU 11 refers to the small dictionary screen management data 12f as described above to delete the small dictionary screen that has not been set to be retained (step A52). Fig.10 As shown, when the small dictionary screen D5s is not set to be kept, when it is detected that the detailed screen D2 is operated by the pen 18 (for example, a sliding operation for scrolling the screen, etc.), the CPU 11 eliminates the small dictionary screen D3s and only displays the small dictionary screens D3s and D4s.

[0108] If not all the mini-dictionary screens are deleted by the selection operation of the close button (step A50, "No"), the CPU 11 executes the processing (steps A44 to A49) according to the instruction operation for the mini-dictionary screen as described above. On the other hand, if all the mini-dictionary screens are deleted (step A50, "Yes"), the CPU 11 returns the display surface of the touch panel 17 to Figure 6 The display status of the detailed screen D1 is shown.

[0109] Thus, for example, it is possible to change the display content of the detailed screen by scrolling, etc., while the information of the multiple words whose meanings are unknown selected from the detailed screen D2 is maintained displayed on the multiple small dictionary screens D3s, D4s, and D5s. Therefore, it is possible to browse the display content (text) displayed on the detailed screen while always referring to the information displayed on the multiple small dictionary screens. Therefore, compared with the case where the small dictionary screen is displayed for each selected word, convenience can be achieved, and the learning effect using the electronic dictionary 10 can be expected.

[0110] Next, a modification of the display format of the mini-dictionary screen will be described.

[0111] Fig.12 FIG. 1 is a diagram showing an example of a display format of an operation button. Fig.11 As shown, when a plurality of small dictionary screens D3s, D4s, and D5s are displayed, the omitted operation buttons can be displayed and selected by sliding the entry jump button on each small dictionary screen. Fig.12 In the example shown, an operation button area D6 including a plurality of operation buttons B61 to B65 is provided for a plurality of mini-dictionary screens D3s, D4s, and D5s. The operation button area D6 includes an entry jump button B61, an example jump button B62, an idiom jump button B63, a speech button B64, and a mark button B65.

[0112] In the case where an operation button area D6 shared by a plurality of small dictionary screens is provided, in order to execute processing by a selection operation of an operation button, first, a touch operation is performed in any small dictionary screen corresponding to a word displayed in the detailed screen D2 set as a processing object to select, and then a touch operation is performed on any operation button in the operation button area D6. The CPU 11 detects this operation, and executes processing corresponding to the operation button selected in the operation button area D6 for the word corresponding to the selected small dictionary screen.

[0113] By always displaying the plurality of operation buttons B61 to B65 in advance in this manner, it is easy to know the processing that can be executed by the selection operation, and even a user who is not yet accustomed to the operation can easily perform the operation.

[0114] In addition, Fig.12 In the figure, the operation button area D6 is arranged at the lower right of the display surface where the small dictionary screen is not displayed, but the operation button area D6 can also be arranged at other positions such as the upper right of the display surface which is not affected by the display of the small dictionary screen and is not easy to hinder the recognition of the display content of the detailed screen D2.

[0115] Fig.13 FIG. 2 is a diagram showing an example of a configuration in which a plurality of mini-dictionary screens are displayed. Fig.10 In the example shown, two small dictionary screens are arranged horizontally, and then an additional small dictionary screen is displayed. The number of display levels is increased and the small dictionary screens are arranged vertically. Fig.13 In the example shown, for example, a plurality of small dictionary screens D71a, D72s, and D73s are arranged only in the vertical direction at the lower left position of the screen. For example, the arrangement of the plurality of small dictionary screens can be changed according to the display format (arrangement) of the content information (text, etc.) displayed on the detail screen D7 so that the area where the content information can be confirmed becomes larger. The position where the plurality of small dictionary screens are displayed is not limited to the lower left position of the screen, and can be set at any position on the display surface of the touch panel 17 according to the display of the content information.

[0116] In addition, in the above description, since the horizontally written text containing English is displayed in the detailed screens D1 and D2, the small dictionary screen is also set to a horizontally long shape. However, in the case where the text displayed on the small dictionary screen is written vertically, the small dictionary screen can also be set to a vertically long shape, and multiple small dictionary screens can be arranged horizontally.

[0117] This makes it possible to avoid significantly hindering the visibility of content information displayed on the detailed screen even when a plurality of mini-dictionary screens are displayed simultaneously.

[0118] Fig.14 FIG. 2 is a diagram showing an example of a configuration in which a plurality of mini-dictionary screens are displayed. Fig.10 In the example shown, a plurality of small dictionary screens D3s, D4s, and D5s are displayed in the same reduced form with the operation buttons omitted, but Fig.14 In the example shown, two small dictionary screens D7s and D8s are displayed in the same reduced form, but other small dictionary screens D3s, D4s, D5s, and D6s are further reduced to, for example, the minimum reduced form of only one line of information displayed in the text area. That is, the display form is set as follows: a part of each of the small dictionary screens D3s, D5s, and D7s is repeated, and a part of each of the small dictionary screens D4s, D6s, and D8s is repeated, and arranged in two rows.

[0119] The small dictionary screen D7s includes a text area D71, an entry jump button B71, and a delete button B76. The small dictionary screen D8s includes a text area D81, an entry jump button B81, and a save button B87.

[0120] exist Fig.14In the example shown, it is assumed that the upper limit of the number of small dictionary screens that can be displayed simultaneously is set to "6". Here, it is assumed that in the detailed screen D2, in a state where three target words AR21 to AR23 are selected, target words AR24 ("Everest"), AR25 ("role"), and AR26 ("always") are further selected in order, and small dictionary screens corresponding to the respective target words are displayed. In other words, it is assumed that the small dictionary screen D6s displayed in response to the selection of the target word AR24 is kept set, the small dictionary screen D7s displayed in response to the selection of the target word AR25 is kept set, and the small dictionary screen D8s is further displayed in response to the selection of the target word AR26.

[0121] exist Fig.14 In the example shown, the mini-dictionary screen corresponding to the last selected target word is preferentially displayed in a reduced format. Fig.14 In the example shown, only two small dictionary screens are displayed in reduced form, so that the two small dictionary screens D7s and D8s corresponding to the two object words AR25 and AR26 selected later are displayed in reduced form first, and the small dictionary screens D3s to D6s are displayed in the most reduced form.

[0122] When displaying a plurality of small dictionary screens in this manner, by not only setting the reduced format with no operation buttons but also setting the reduced format with only one line of information displayed in the text area, it is possible to avoid the display size of the detail screen D2 from being significantly reduced.

[0123] like Fig.14 As shown, in the mini-dictionary screen set to the most reduced form, a part of the information retrieved by the search process including the target word selected in the detailed screen D2 is displayed, so that the correspondence with the target word displayed in the detailed screen D2 can be easily determined. The mini-dictionary screen set to the most reduced form is displayed in a reduced form, for example, according to a touch operation performed by the pen 18, so that the entire information displayed in the text area can be browsed, and various processes can be executed by operating instructions on the operation buttons.

[0124] Moreover, the information corresponding to the word selected later as the target word is easier for the user to refer to, so by preferentially displaying the small dictionary screen corresponding to the word selected later as the target word in a reduced form, the small dictionary screen can be efficiently and flexibly used.

[0125] In addition, Fig.14 In the display format shown, a plurality of small dictionary screens are arranged in two rows, and a portion of the small dictionary screens are repeated in each row. However, the small dictionary screens may be repeated in one row, and the range of the repetition may be different.

[0126] Next, a description will be given of a setting process for setting setting data related to the mini-dictionary function.

[0127] For example, when the start of the setting process is instructed by operating a setting button provided on the main screen, CPU 11 causes touch panel 17 to display a setting screen. In the setting screen, for example, a plurality of setting items including setting items related to the "mini dictionary function" are prepared.

[0128] When a setting item related to the "mini dictionary function" is selected by a user operation, the CPU 11 displays, for example, Fig.15 The setting screen related to the "mini dictionary function" as shown.

[0129] exist Fig.15 In the setting screen shown, for example, a "1" button SB11 is provided for setting only one small dictionary screen to be displayed at the same time, and a "multiple" button SB12 is provided for setting a plurality of small dictionary screens to be displayed at the same time. The "1" button SB11 is a button for setting the execution of the following processing: when a target word is selected from the text displayed on the detail screen D1, a small dictionary screen corresponding to the target word is displayed, and when a further target word is selected, the previously displayed small dictionary screen is deleted and a small dictionary screen corresponding to the newly selected target word is displayed. As described above, the "multiple" button SB12 is a button for setting the execution of the processing that enables a plurality of small dictionary screens to be displayed at the same time.

[0130] In addition, Fig.15 In the setting screen shown, quantity setting buttons SB21, SB22, and SB23 are provided for setting the upper limit number that can be displayed when the display of multiple mini-dictionary screens is set by the "multiple" button SB12. Quantity setting button SB21, quantity setting button SB22, and quantity setting button SB23 are buttons for setting the upper limit number "2", the upper limit number "4", and the upper limit number "6", respectively. In addition, instead of selecting a certain predetermined upper limit number, it is also possible to set an arbitrary upper limit number.

[0131] The setting contents set in the setting screen are stored as setting data 12d, and are referred to when the mini-dictionary function is executed.

[0132] In this way, according to the setting operation performed by the user through the setting screen, whether to display multiple small dictionary screens at the same time can be changed. When multiple small dictionary screens are displayed, the upper limit number of small dictionary screens displayed simultaneously can be changed, thereby providing each user with good operability with ease of use.

[0133] In addition, in the above description, the mini-dictionary function is executed when a word selection operation is performed on the text displayed on the detailed screen as the search result of the search function, but the mini-dictionary function can also be executed when a word selection operation is performed on other text. For example, when a text of a literary work, a reference manual, etc. included in the content information data 12e is displayed on the touch panel 17, when an operation of selecting a word in the text is performed (using a sliding operation of the pen 18, etc.), the information retrieved by the mini-dictionary function is displayed in the text area of ​​the mini-dictionary screen in the same way as described above.

[0134] In addition, in the above description, a small dictionary screen is additionally displayed each time a target word is selected from the detailed screen and a plurality of small dictionary screens are displayed at the same time, but the display / non-display of the small dictionary screen may be switched according to the user operation. For example, when the small dictionary screen displayed on the touch panel 17 is set to be retained, the CPU 11 stores the small dictionary screen in advance in the memory 12 as a search history of the small dictionary function for the target word. Then, even if the small dictionary screen is deleted due to exceeding the upper limit number for additional display, for example, when the display of the search history is instructed by the user operation on the "History" button, the CPU 11 reads out the plurality of small dictionary screens stored as the search history from the memory 12 and displays them at a glance on the touch panel 17.

[0135] In this way, the small dictionary screen can be displayed as a search history as needed, so that in normal use, the small dictionary screens are limited to one or two, and the display area of ​​the detail screen D2 (main screen) is relatively large. In addition, when the contents of multiple small dictionary screens are to be browsed or various processes are to be performed by operating the operation buttons, they can be displayed as needed by operating the "History" button. Therefore, the small dictionary function can be more effectively and flexibly used.

[0136] In addition, the method described in the embodiment, that is, Figure 3 to Figure 5 The processing methods shown in the flowcharts can be distributed as computer-executable programs stored in a storage card (ROM card, RAM card, etc.), a disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), a semiconductor memory, and other recording media. Then, the computer can realize the same processing as the functions described in the embodiment by reading the program recorded in the external recording medium and controlling the operation by the program.

[0137] In addition, the data of the program used to implement each method can be transmitted on the network (Internet) in the form of program code, and the program data can also be obtained from a computer (server device, etc.) connected to the network (Internet) to achieve the same functions as the aforementioned implementation method.

[0138] In addition, the invention of the present application is not limited to the implementation mode, and various modifications can be made in the implementation stage without departing from the main purpose. Moreover, the implementation mode includes inventions at various stages, and various inventions can be extracted by appropriate combinations of the disclosed multiple constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in the implementation mode or some constituent elements are combined, the problem described in the problem column to be solved by the invention can be solved and the effect described in the invention effect column can be obtained, and the structure after deleting or combining the constituent elements can also be extracted as an invention.
