The classification information storage area 901 stores classification information read from the text data 830 in a word book creation process (see FIG. 6) described later.

[Operation]
Next, the operation of the electronic dictionary 1 will be described with reference to FIGS.

  FIG. 6 is a flowchart showing the flow of a word book creation process in which the CPU 20 reads and executes the word book creation program 81. Moreover, FIG. 7 is a figure which illustrates the display content of the main display 10 in a word book creation process. In this word book creation process, when the user inputs an instruction to execute the word book creation process via the touch panel 31 or the key group 2, the word book creation program 81 is read from the flash ROM 80 and appropriately expanded in the RAM 90. As a result, the word book creation program 81 and the CPU 20 cooperate with each other.

  As shown in FIG. 6, when the word book creation process is executed, the CPU 20 first reads the text data 830 from the outside via the interface 50 and stores it in the flash ROM 80 (step S1). In the present embodiment, it is assumed that text data 830b (see FIG. 4) created by the user is read in step S1.

  Next, the CPU 20 causes the user to designate the dictionary database 820 associated with each word in the word book as the designated dictionary database 820S, and stores the dictionary name of this dictionary database 820 in the designated dictionary storage area 900 (step S2). Then, a character string is extracted for each word from the read text data 830b (step S3).

  Next, the CPU 20 determines whether or not the extracted character string is classification information based on the presence or absence of the at sign “@” (step S4), and determines that the extracted character string is classification information (step S4; Yes). The character string classification information is stored in the classification information storage area 901 to update the information in the classification information storage area 901 (step S5), and the process proceeds to step S6 described later.

  If it is determined in step S4 that the character string is not classification information (step S4; No), the CPU 20 determines whether or not a headword corresponding to the character string is included in the designated dictionary database 820S. (Step S7).

  When it is determined in step S7 that the headword is included in the designated dictionary database 820S (step S7; Yes), the CPU 20 stores the headword, the dictionary name of the designated dictionary database 820S, and the classification information storage area 901. Are stored in the word book table 84 in association with each other (step S8), and the process proceeds to step S6 described later. As a result, the plurality of words extracted from the text data 830 b are classified according to the classification information and stored in the word book table 84.

  If it is determined in step S7 that the entry word is not included in the designated dictionary database 820S (step S7; No), the CPU 20 memorizes the character string extracted in step S3 as the contents of one side of the memorization card. Temporarily registered in the card data 850 (step S9).

  Next, the CPU 20 determines whether or not the extraction has been completed up to the last character string of the text data 830b (step S6). When it is determined that the extraction has not ended (step S6; No), the above-described step is performed. The process proceeds to S3.

  On the other hand, if it is determined in step S6 that the extraction has ended (step S6; Yes), the CPU 20 determines whether there is a character string temporarily registered in the memorization card database 85 (step S10), and there is no character string. Is determined (step S10; No), the word book creation process is terminated.

  On the other hand, if it is determined in step S10 that there is a temporarily registered character string, that is, if a headword corresponding to the extracted character string is not included in the designated dictionary database 820S (step S10; Yes), the CPU 20 Then, by performing a spell check on the character string, at least one character string similar to the character string is generated and displayed in a list on the main display 10, and one of the character strings is a character string of a word to be corrected To be selected by the user (step S11). For example, as shown in FIG. 4 and FIG. 7A, when the character string “arrengement” is included in the text data 830 b, the entry word corresponding to this character string is not included in the dictionary database 820. Therefore, similar character strings “amendment”, “atonement”,... Are created and displayed in a list. FIG. 7A shows a state where the user has selected “arrangement” as the character string of the word to be corrected. Moreover, a conventionally well-known method can be used as such a spell check method.

  Next, the CPU 20 retrieves a headword corresponding to the character string of the correction target word selected by the user from the designated dictionary database 820S, stores the retrieved headword, the dictionary name of the designated dictionary database 820S, and the classification information storage. The classification information in the area 901 is associated with and stored in the word book table 84 (step S12).

  Next, the CPU 20 causes the main display 10 to display a screen for creating the memorization card for the correction destination word and the handwriting input screen to the sub display 11 (step S13). Handwritten input about the explanation information and the like is received from the touch panel 31 of the sub display 11. In the memorization card creation screen in the present embodiment, for example, as shown in FIG. 7B, a selection button 101 for selecting a writing target surface out of both surfaces of the memorization card, and a correction destination word Is displayed.

  Then, after the user selects one side with the selection button 101, the character string of the correction destination word is handwritten on the sub-display 11, and after selecting the other side with the selection button 101, the explanation corresponding to the correction destination word When information or the like is input to the touch panel 31 by handwriting, the CPU 20 creates the memorized card data 850 by associating the handwritten image of the correction target word with the handwritten image such as the explanation information, and stores it in the flash ROM 80 (step S14). ), The word book creation process is terminated.

  When the words in the text data 830b are registered in the word book as described above, the user operates the word book key 2i, so that the dictionary registered in the word book as shown in FIG. 7C. Names (language names) and classification information are displayed in a list on the main display 10. Next, when the user selects any dictionary name or classification information, a list of words associated with the selected dictionary name or classification information in the word book table 84 is displayed. When the user selects any word, the description information of the headword corresponding to the word is retrieved from the dictionary database 820 associated with the selected word and displayed on the main display 10.

  Further, when the memorized card data 850 is created as in step S14, the contents of both sides of the memorized card data 850 are sequentially displayed on the main display 10 by the user performing a predetermined operation. Become.

  According to the electronic dictionary 1 described above, as shown in steps S3 and S8 of FIG. 6, FIG. 7, etc., a plurality of words are extracted from the text data 830b, and the dictionary database includes headwords corresponding to the extracted words. Since the corresponding word is accumulated and stored in the word book table 84 in association with 820S, a plurality of words in the text data 830b are collectively registered in the word book. Therefore, a plurality of words can be easily registered in the word book as compared with the conventional case in which a word is searched for one by one and registered.

  Further, as shown in steps S3 to S8 in FIG. 6, FIG. 7C, and the like, the words extracted from the text data 830b are classified and stored according to the classification information, so that the words are stored in a plurality of types of word books. Can be classified and registered.

  Further, as shown in steps S9 and S13 to S14 of FIG. 6 and FIGS. 7A and 7B, a headword corresponding to a character string extracted as a word from the text data 830b is included in the designated dictionary database 820S. If at least one character string similar to this character string is generated and one of the character strings is selected as the character string of the correction target word based on the user operation, Since the handwritten input is accepted, and the memorized card data 850 is created using the input handwritten image as the contents of one side of the memorized card, the memorized card is created for the wrong word in the text data 830b. Become. Accordingly, since a memorization card is created for a word with ambiguous memory, the learning effect can be enhanced.

(Second Embodiment)
Next, a second embodiment of the electronic dictionary according to the present invention will be described. In addition, when the part corresponding mutually with the said 1st Embodiment is comprised similarly, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

[Constitution]
The flash ROM 80A of the electronic dictionary 1A in the present embodiment includes a word book creation program 81A as shown in FIG.

  The word book creation program 81A is a program for causing the CPU 20 to execute a word book creation process (see FIG. 8) described later.

[Operation]
Next, the operation of the electronic dictionary 1A will be described with reference to FIGS.

  FIG. 8 is a flowchart showing the flow of a word book creation process in which the CPU 20 reads and executes the word book creation program 81A. Moreover, FIG. 9 is a figure which illustrates the display content of the main display 10 in a word book creation process. In this word book creation process, when the user inputs an instruction to execute the word book creation process via the touch panel 31 or the key group 2, the word book creation program 81A is read from the flash ROM 80A and appropriately expanded in the RAM 90. As a result, the word book creation program 81A and the CPU 20 are executed in cooperation.

  As shown in FIG. 8, when the word book creation process is executed, the CPU 20 first reads the text data 830 from the outside via the interface 50 and stores it in the flash ROM 80 (step T1). In the present embodiment, it is assumed that text data 830a (see FIG. 9A) created by the user is read in step T1.

  Next, the CPU 20 causes the user to designate the dictionary database 820 associated with each word in the word book as the designated dictionary database 820S, and stores the dictionary name of this dictionary database 820 in the designated dictionary storage area 900 (step T2).

  Next, as shown in FIG. 9A, the CPU 20 displays the read text data 830a on the main display 10 (step T3). In step T3, the CPU 20 enters a standby state for a selection operation by the user for the words in the displayed text data 830a and the marker colors (classification marks) for classifying the words in the word book. In the present embodiment, when the user performs a marker color change operation, as shown in FIG. 9B, a marker color setting screen is displayed on the main display 10, and is displayed in red, yellow, or green. Any marker color can be selected. In the present embodiment, the red marker color means that the selected word is registered in the word book and the memorization card. The yellow marker color means that the selected word is registered in the word book with the classification “Need attention”. The green marker color means that the selected word is registered in the word book with the classification of “easy to forget”.

  Next, the CPU 20 determines whether or not a word in the displayed text data 830a is selected by the user (step T4).

  When it is determined in step T4 that no word is selected (step T4; No), the CPU 20 determines whether any marker color is selected by the user (step T5), and determines that it is not selected. If so (step T5; No), the process proceeds to another process. If it is determined in step T5 that the marker color has been selected (step T5; Yes), the CPU 20 sets the marker color selected by the user as the marker color for word classification, and the classification information storage area 901 And the information in the classification information storage area 901 is updated (step T6), and the process proceeds to step T4 described above.

  If it is determined in step T4 that a word has been selected (step T4; Yes), the CPU 20 selects the selected word with the set marker color based on the information in the classification information storage area 901. A marker is displayed (step T7).

  Next, the CPU 20 determines whether or not a user operation for instructing registration in the word book is performed (step T8). If it is determined that the user operation is not performed (step T8; No), the process proceeds to the above-described step T4. To do. Then, by repeating the above steps T4 to T8, the text data 830a is displayed on the main display 10 with a plurality of words displayed as markers, for example, as shown in FIG. 9C. It becomes. In this figure, the word “nervous” is displayed in red with a marker, and the word “procedure” is displayed in yellow with a marker.

  If it is determined in step T8 that an operation for instructing registration has been performed (step T8; Yes), the CPU 20 determines whether or not there is a word displayed in red, that is, in the word book and the memorization card. It is determined whether there is a word to be registered (step T9).

  When it is determined in step T9 that there is no word displayed with a marker in red (step T9; No), the CPU 20 extracts the word displayed with a marker in each color from the text data 830a, and extracts each word and the designated dictionary. The dictionary names in the database 820S are associated with each other and stored in the word book table 84 (step T12), and the word book creation process is terminated. More specifically, in this step T12, for the word displayed in the yellow and green marker colors, the CPU 20 associates the classification information of “Caution required” and “Easy-to-forget” with the word word table 84. To memorize. As a result, the plurality of words extracted from the text data 830 b are classified according to the marker color (classification mark) and stored in the word book table 84.

  On the other hand, if it is determined in step T9 that there is a red marker-displayed word (step T9; Yes), the CPU 20 displays a memorization card creation screen for this word (hereinafter referred to as a memorization card creation word). A handwriting input screen is displayed on the main display 10 on the sub-display 11 (step T10), and the handwriting input about the contents of both sides of the memorization card, that is, the memorized card creation word and its explanation information, etc. is performed. Accept from. In the memorization card creation screen in the present embodiment, for example, as shown in FIG. 9 (d), a selection button 101 for selecting a writing target surface out of both sides of the memorization card, and a memorization card creation word Is displayed.

  Then, after the user selects one side with the selection button 101, the character string of the memorized card creation word is handwritten on the sub-display 11, and after selecting the other side with the selection button 101, the memorized card created word is supported. When the explanatory information to be written is input to the touch panel 31 by handwriting, the CPU 20 creates the memorized card data 850 by associating the handwritten image of the memorized card created word and the handwritten image such as the explained information, and stores them in the flash ROM 80. (Step T11), the process proceeds to Step T12 described above.

  When the words in the text data 830a are registered in the word book as described above, the dictionary name (language name) and classification information registered in the word book are stored in the main by operating the word book key 2i. A list is displayed on the display 10. Next, when the user selects any dictionary name or classification information, a list of words associated with the selected dictionary name or classification information in the word book table 84 is displayed. When the user selects any word, the description information of the headword corresponding to the word is retrieved from the dictionary database 820 associated with the selected word and displayed on the main display 10.

  Further, when the memorized card data 850 is created as in the above-described step T14, the contents of both sides of the memorized card data 850 are sequentially displayed on the main display 10 by the user performing a predetermined operation. Become.

  According to the electronic dictionary 1A described above, the same effects as those of the electronic dictionary 1 in the first embodiment can be obtained, as shown in steps T4 to T8 in FIG. 8, FIG. 9, and the like. When any word in the displayed text data 830a is selected based on a user operation and a marker color for classifying the word is selected from red, blue, and yellow based on the user operation, the selected word is selected. Since the selected word is classified based on the marker color, the word can be classified and registered in a plurality of types of word books.

  In addition, as shown in steps T9 to T11 of FIG. 8 and FIGS. 9C and 9D, handwritten input for words classified by the red marker color is accepted, and the input handwritten image is memorized. Since the memorized card data 850 is created as the contents of one side of the card, the memorized card can be created for any word in the text data 830a.

  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.
