The handwriting information input by the user through the touch panel 11a is stored. The character string storage area 93 stores a character string in which the handwriting information is recognized.

[Operation]
Next, the operation of the electronic dictionary 1 will be described.
4 to 8 are flowcharts showing the flow of dictionary search processing in which the CPU 20 reads and executes the information display program 81.

  First, as shown in FIG. 4, the CPU 20 determines whether or not the dictionary selection key 2d is operated by the user (step S1), and when it is determined that the user does not operate (step S1; No), other processing is performed. Migrate to

  If it is determined in step S1 that the dictionary selection key 2d has been operated (step S1; Yes), the CPU 20 selects the dictionary name of the dictionary database 84 corresponding to the operated dictionary selection key 2d as the selected dictionary storage area 91. Then, it is determined whether or not the collective input mode key 2h is operated by the user (step S2).

  If it is determined in step S2 that the batch input mode key 2h is not operated (step S2; No), the CPU 20 proceeds to another process, and if it is determined that it is operated (step S2; Yes), Processing in a batch input mode in which a plurality of unknown words can be input / searched at the same time is started, and handwriting information storage processing is first performed (step S3).

  In the handwriting information storage process in step S3, as shown in FIG. 5, the CPU 20 has a plurality of handwriting information areas 101,... And an “input end” instruction area 102 (FIG. 9) on the main display 10 as handwriting information input screens. (A) is displayed, and the input frame 113 and the “correction” instruction area 114 (see FIG. 9A) are displayed on the sub-display 11 as a handwriting input screen (step S31).

  Next, the CPU 20 determines whether or not an input to the blank input frame 113 on the sub-display 11 (touch panel 11a) is performed by the user (step S32), and when it is determined that no input is performed (step S32). ; No), the CPU 20 repeats the step S32.

  If it is determined in step S32 that input to the input frame 113 has been performed (step S32; Yes), the CPU 20 determines whether or not the user performs a touch operation on the “correction” instruction area 114. (Step S33).

  If it is determined in step S33 that a touch operation has been performed on the “correction” instruction area 114 (step S33; Yes), the CPU 20 inputs handwriting information that has already been input by handwriting at the time of determination in step S33. If it is erased from the frame 113 and the process proceeds to step S32 described above and it is determined that the touch operation is not performed (step S33; No), it is determined whether or not the translation / decision key 2b is operated by the user. (Step S34).

  If it is determined in step S34 that the translation / decision key 2b has been operated (step S34; Yes), the CPU 20 uses the handwriting information that has been input by handwriting at the time of the determination in step S34 as image information. After being stored in the storage area 92 and displayed in the handwriting information area 101 of the main display 10 (step S35), the handwriting information is erased from the input frame 113 of the sub-display 11, and the process proceeds to step S32.

  And by repeating step S32-S35, several handwriting information is memorize | stored in the handwriting information storage area 92, and is displayed on the handwriting information area 101, ... of the main display 10. FIG. At this time, handwriting information is displayed in order from the top in a plurality of handwriting information areas 101,... For each operation of the translation / decision key 2b.

  On the other hand, if it is determined in step S34 that the translation / decision key 2b is not operated (step S34; No), the CPU 20 performs a touch operation on the “input end” instruction area 102 of the main display 10 by the user. It is determined whether or not (step S36).

  When it is determined in step S36 that the touch operation to the “input end” instruction area 102 is not performed (step S36; No), the CPU 20 proceeds to the above-described step S32 and determines that the touch operation is performed. If it has been performed (step S36; Yes), the handwriting information storage process is terminated.

Next, as shown in FIG. 4, the CPU 20 performs handwriting information recognition processing (step S4).
In the handwriting information recognition process in step S4, as shown in FIG. 6, the CPU 20 uses the handwriting information area 101 in which the handwriting information is displayed in step S3 described above as a handwriting information recognition screen, and the handwriting information area. In addition to the recognition check boxes 103 corresponding to 101, a “check all” instruction area 104, a “recognition” instruction area 105, and a “recognition end” instruction area 106 (see FIG. 10A) are displayed on the main display 10. (Step S41).

  Next, the CPU 20 determines whether or not the user performs a touch operation on the recognition check boxes 103,... Or the “check all” instruction area 104 (step S42). When it is determined that the touch operation is not performed (Step S42; No), the CPU 20 repeats Step S42, and when it is determined that the touch operation is performed (Step S42; Yes), the recognition check is performed. When a touch operation on only the box 103 is performed, a check mark is displayed in the recognition check box 103 on which the touch operation is performed, and when a touch operation on the “check all” instruction area 104 is performed, all recognition checks are performed. After displaying a check mark in the boxes 103,..., It is determined whether or not the user performs a touch operation on the “recognition” instruction area 105 (step S43).

  When it is determined in step S43 that the touch operation on the “recognition” instruction area 105 is not performed (step S43; No), the CPU 20 proceeds to the above-described step S42 and determines that the touch operation is performed. In the case (step S43; Yes), all the handwriting information in the handwriting information area 101 corresponding to the recognition check box 103 on which the check mark is displayed is recognized as a character string and stored in the character string storage area 93. . At the same time, a character string area 107 (see FIG. 10C) is displayed instead of the handwriting information area 101 on which the handwriting information is displayed, and the character string recognized as a character is displayed in the character string area 107. In addition, a “correction” instruction area 108 (see FIG. 10C) is displayed at the end of each character string area 107 (step S44).

  Next, the CPU 20 determines whether or not the user performs a touch operation on the “correction” instruction area 108 (step S45), and determines that the touch operation has been performed (step S45; Yes), that is, When the character string in the character string area 107 corresponding to the “correction” instruction area 108 on which the touch operation has been performed is selected as the character string to be corrected, the character string to be corrected is deleted from the character string area 107 and combined. Then, the character string stored in the character string storage area 93 in step S44 is deleted (step S46). Then, only the character string area 107 from which the character string has been deleted is subjected to handwriting information storage processing in the same manner as in step S3 described above, and new handwritten information is input (step S47), and then the above described step S42. Migrate to Then, the CPU 20 recognizes and stores the input new handwriting information as a new character string through the processing of steps S42 to S44, and replaces it with the correction target character string.

  When it is determined in step S45 that the touch operation is not performed (step S45; No), the CPU 20 determines whether or not the user performs a touch operation on the “recognition end” instruction area 106. (Step S48). When it is determined that the touch operation on the “recognition end” instruction area 106 is not performed (step S48; No), the CPU 20 proceeds to the above-described step S41 and determines that the touch operation is performed. In (Step S48; Yes), the character strings recognized as characters are displayed in a list on the main display 10 (Step S49), and the handwriting information recognition process is terminated.

Next, as shown in FIG. 4, the CPU 20 performs a recognized character string search process (step S5).
In the recognized character string search process in step S5, as shown in FIG. 7, the CPU 20 displays, as a character string search screen, a character string area 107,... Where the character string recognized in step S4 is displayed. In addition to the search check boxes 109,... Corresponding to the character string areas 107,..., A “check all” instruction area 110 and a “search” instruction area 111 (see FIG. 11A) are displayed on the main display 10 (see FIG. 11A). Step S50).

  Next, the CPU 20 determines whether or not the user performs a touch operation on the search check box 109,... Or the “check all” instruction area 110 (step S51). When it is determined that the touch operation is not performed (step S51; No), the CPU 20 repeats the step S51, and when it is determined that the touch operation is performed (step S51; Yes), the search check is performed. When a touch operation on only the box 109 is performed, a check mark is displayed in the search check box 109 on which the touch operation is performed, and when a touch operation on the “check all” instruction area 110 is performed, all search checks are performed. After displaying check marks in the boxes 109,..., It is determined whether or not the user performs a touch operation on the “search” instruction area 111 (step S52).

  When it is determined in this step S52 that the touch operation to the “search” instruction area 111 is not performed (step S52; No), the CPU 20 proceeds to the above-described step S51 and determines that the touch operation is performed. In the case (step S52; Yes), the uppermost check character string of all the character strings (check character strings) in the character string area 107 corresponding to the search check box 109 in which the check mark is displayed in step S51 described above. Is set as a search word, and a headword corresponding to the search word is searched from the dictionary database 84 stored in the selected dictionary storage area 91 (step S53).

  Next, the CPU 20 displays a list of headwords detected by the headword search in step S53 on the main display 10 (step S54). At this time, the CPU 20 highlights the first headword in the headword list, and also includes dictionary information including the headword, that is, the headword and its explanation information, and the “list return” instruction area 115. (See FIG. 11C) is displayed on the main display 10. Here, when a headword other than the head word is selected from the headword list by the user operating the cursor key 2e and the translation / decision key 2b, the CPU 20 selects the selected headword. Is read from the dictionary database 84 and displayed on the main display 10.

  Next, the CPU 20 determines whether or not check marks are displayed in the plurality of search check boxes 109 in step S51 described above, that is, whether or not there are a plurality of check character strings (step S55). If there is only one (step S55; No), the recognized character string search process is terminated. If there are a plurality of check character strings (step S55; Yes), the “next search” instruction area 112 (FIG. 11 (c) )) Is displayed on the main display 10 (step S56). The display of the “next search” instruction area 112 is performed almost simultaneously with the list display of headwords in step S54 described above.

  Next, the CPU 20 determines whether or not the user performs a touch operation on the “next search” instruction area 112 (step S57). When it is determined that the touch operation is not performed (step S57; No), the CPU 20 ends the recognized character string search process, and when it is determined that the touch operation is performed (step S57; Yes). In place of the check character string that has been the search word at the time of determination in step S57, the check character string in the next stage of the check character string is set as the search word, and the head word corresponding to the search word is set. After searching from the dictionary database 84 (step S58), the process proceeds to step S54 described above.

  When the above recognized character string search processing is completed, as shown in FIG. 4, the CPU 20 next determines whether or not the user performs a touch operation on the “return list” instruction area 115 (step S <b> 6). . If it is determined that a touch operation has been performed (step S6; Yes), the CPU 20 proceeds to step S5 described above to display a list of character strings that have been recognized on the main display 10, and the touch operation is performed. If it is determined that it is not received (step S6; No), the dictionary search process is terminated.

In addition, the character string stored in the character string storage area 93 in the above-described step S44 can be called again and used for the headword search even after the dictionary search process is completed.
The operation of the electronic dictionary 1 at this time will be described.

  First, as shown in FIG. 8, the CPU 20 determines whether or not the user operates the shift key 2f and the menu key 2g in combination (step T1), and determines that the shift key 2f and the menu key 2g are not operated. In (Step T1; No), the process proceeds to another process.

  If it is determined that the shift key 2f and the menu key 2g are operated (step T1; Yes), the CPU 20 calls the character strings stored in the character string storage area 93 and displays them on the main display 10 as a list. (Step T2) A recognition character string search process is performed in the same manner as in Step S5 (Step T3).

[Operation example]

  First, as shown in FIG. 9A, when the user operates the English-Japanese dictionary selection key 2d (b) (step S1; Yes) and the collective input mode key 2h (step S2; Yes), the main An input screen for handwriting information is displayed on the display 10, and a handwriting input screen is displayed on the sub-display 11 (step S31).

  When the character “design” is input by handwriting into the blank input frame 113 of the sub-display 11 (step S32; Yes) and the translation / decision key 2b is operated (step S33; No, step S34; Yes), As shown in FIG. 9B, the character “design” is displayed as the handwriting information in the uppermost handwriting information area 101 of the main display 10 without changing the handwriting state (step S35).

  Next, as shown in FIG. 9C, by repeating the same operation, the handwriting information “jew” and “lean” are continuously input, and the first stage of the handwriting information area 101 in which the handwriting information “design” is displayed. Displayed in order from the bottom row.

  When a touch operation on the “input end” instruction area 102 is performed (step S36; Yes), as shown in FIG. 10A, a handwriting information recognition screen is displayed on the main display 10 (step S41). ).

  Next, as shown in FIG. 10B, a touch operation is performed on the recognition check box 103 corresponding to the handwriting information area 101 in which the handwriting information “design” and “lean” is displayed (step S42; Yes). When the touch operation on the “recognition” instruction area 105 is performed (step S43; Yes), as shown in FIG. 10C, the handwriting information “design” and “lean” is recognized as a character string, and the handwriting is written. It is displayed in the updated character string area 107 instead of the information area 101 (step S44).

  Then, when a touch operation is performed on the “recognition end” instruction area 106 (step S45; No, step S48; Yes), as shown in FIG. 11A, the character strings “design”, “character recognition” are performed. Only “lean” is displayed as a list on the main display 10 (step S49), and a character string search screen is displayed (step S50).

  Next, as shown in FIG. 11B, a touch operation is performed on the search check box 109 corresponding to the character string area 107 in which the character strings “design” and “lean” are displayed (step S51; Yes). When the “search” instruction area 111 is touched (step S52; Yes), as shown in FIG. 11C, the headwords “design” and “designate” corresponding to the search word “design” are displayed. Are retrieved from the dictionary database 84b (step S53) and displayed as a list on the main display 10 (step S54). At this time, the first headword “design” is highlighted and the explanation information of the headword “design” is also displayed on the main display 10.

Then, when a touch operation is performed on the “next search” instruction area 112 (steps S55; Yes, S56, S57; Yes), as shown in FIG. 11 (d), an entry corresponding to the search word “lean” is found. The words “lean ¹ ”, “lean ² ” and the like are retrieved from the dictionary database 84 ^b (step S 58) and displayed as a list on the main display 10 (step S 54). At this time, the ^first headword “lean ¹ ” is displayed in reverse video, and the explanation information of the headword “lean ¹ ” is also displayed on the main display 10.

<Operation example 2>
In the second operation example, after the dictionary search process is completed once the character strings “design” and “lean” are stored in the first operation example, the character strings “design” and “lean” are called again and viewed. The operation when searching for words is described.

  First, as shown in FIG. 12A, when the user operates the shift key 2f and the menu key 2g in combination (step T1; Yes), the stored character strings “design” and “lean” are displayed on the main display 10. (Step T2), and a character string search screen is displayed.

  Then, the headword search is performed as in the first operation example (step T3). Specifically, as shown in FIG. 12B, a touch operation is performed on the search check box 109 corresponding to the character string area 107 in which the character strings “design” and “lean” are displayed, and “search” is performed. When the touch operation on the instruction area 111 is performed, as shown in FIG. 12C, the headwords “design”, “designate”, and the like corresponding to the search word “design” are retrieved from the dictionary database 84b and main. A list is displayed on the display 10. At this time, the first headword “design” is highlighted and the explanation information of the headword “design” is also displayed on the main display 10.

Then, when a touch operation on the “next search” instruction area 112 is performed, the headwords “lean ¹ ”, “lean ² ” and the like corresponding to the search word “lean” are displayed as shown in FIG. It is searched from the dictionary database 84b and displayed as a list on the main display 10. At this time, the ^first headword “lean ¹ ” is displayed in reverse video, and the explanation information of the headword “lean ¹ ” is also displayed on the main display 10.

  According to the electronic dictionary 1 described above, as shown in steps S32 to S35 of FIG. 5, step S44 of FIG. 6, steps S51 to S54 of FIG. 7, FIGS. A list of information is displayed on the main display 10, characters are recognized as character strings, set as search words, and dictionary information including head words corresponding to the search words is displayed. Can be displayed and temporarily stored, and then the entry word search can be sequentially performed for each handwriting information. Therefore, unlike the conventional case in which handwriting information recognition processing and explanation information display processing that require a certain amount of time and confirmation processing of the explanation information by the user are performed for each handwriting information, a plurality of unknown words are generated in succession. Even in such a case, it is possible to surely search for a headword.

  Also, as shown in step S42 of FIG. 6 and FIG. 10, any handwriting information among a plurality of handwriting information is recognized and used as a search word, and therefore a plurality of handwritings temporarily accumulated as unknown words / phrases. From the information, it is possible to appropriately select only what is desired to be searched and to search for a headword. Therefore, for example, if you write down multiple unknown words at a meeting, etc., omit the unknown words whose meaning has been clarified during the subsequent meeting, etc., and search only the necessary unknown words. Can do.

  Also, as shown in steps S53 to S58 in FIG. 7 and as shown in FIG. 11, when there are a plurality of set search terms, the search terms used for the search can be switched according to the user operation. From the plurality of search terms, it is possible to appropriately select only the ones that are desired to be searched and perform a search for the found terms.

  In addition, when there are a plurality of character strings recognized as shown in steps S51 and S52 of FIG. 7 or FIG. 11, an arbitrary character string of the plurality of character strings is searched according to a user operation. Since it is set as a word, it is possible to appropriately select only what is desired to be searched from a plurality of character strings recognized as unknown words and perform a word search.

  Further, as shown in step S44 of FIG. 6 and FIGS. 8 and 12, when a character string recognized as a character is stored and there are a plurality of stored character strings, an arbitrary one of the plurality of character strings is stored. Since the character string is set as a search word according to the user's operation, even if the word search is terminated once after storing the character string, the stored character string list is called after that. From the list, it is possible to appropriately select only what is desired to be searched and to search for a word.

  Further, as shown in steps S42 to S47 of FIG. 6, an arbitrary character string among the character strings recognized as characters is selected as a correction target character string, and the newly input handwriting information is set as a new character string. Since character recognition is performed and replaced with the correction target character string, even if erroneously recognized handwriting information exists, only the erroneously recognized handwriting information can be re-input and corrected.

  Also, as shown in step S35 of FIG. 5, a plurality of input handwriting information is stored. For example, even when it is desired to check handwriting information itself, not a character string obtained by character recognition of handwriting information. The handwriting information can be called up as necessary.

  The embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

  For example, the electronic device according to the present invention has been described as the electronic dictionary 1, but those to which the present invention can be applied are not limited to such products, but are mobile phones, personal computers, PDAs (Personal Digital Assistants), game machines, and the like. It can be applied to all electronic devices. Further, the information display program 81 according to the present invention may be stored in a memory card, CD, or the like that can be attached to and detached from the electronic dictionary 1.

  Further, when a search word is searched for an entry word, an arbitrary entry word may be selected by a user operation, registered as a word book, and stored in the word book table 85,.

  In the above embodiment, the dictionary selection is described as being performed at the beginning of the dictionary search process. However, for example, the dictionary is selected when the touch operation to the “search” instruction area 111 is performed (step S52). Also good.

  Although the handwriting information is described as being stored in the handwriting information storage area 92, the handwriting information may be temporarily accumulated so that a plurality of handwriting information is displayed on the main display 10 without being stored.
