[First operation example]
Next, a first operation example of the above embodiment will be described.
FIGS. 3 and 4 are flowcharts showing content display and learning book registration processing, which is controlled by the CPU 21 in the electronic dictionary device 10.
FIG. 5 is a diagram showing the display screen and the contents of the registered learning book in the process of registering the learning book.
In this embodiment, after selecting “Japanese history” as the dictionary / textbook content, the word “Peace” is the main keyword, and several related words are named “Memocure study book A”. A case where registration is performed in association with one group will be described.

  In this operation, for example, as shown in FIG. 5 (A) -2, for one group in the study book named “memorization study book A”, “Heian” which is the main keyword first, In addition, the keywords “Uji” and “Byodo-in Temple” are set to be associated with each other.

  3 and 4, the CPU 21 first prompts the user to select a dictionary / textbook content by displaying on the color liquid crystal display screen 17d. On the other hand, "Japanese history" is selected by the dictionary designation key 14b (step S101). Then, the user is prompted to select whether or not to select the main keyword from the table of contents heading by displaying on the color liquid crystal display screen 17d (step S102).

  On the other hand, when the user performs an operation on the transparent touch panel 17t so as not to select from the headline of the table of contents, the CPU 21 that has received it next determines whether or not to search from each headword W in the content, whether or not color The user is prompted to select by display on the liquid crystal display screen 17d (step S122).

  Here again, when the user inputs that the search is not performed from the entry word W by an operation on the transparent touch panel 17t, the CPU 21 next determines whether or not to perform a search for the entire entry word W and the text information T. The user is prompted to select by display on the display screen 17d (step S125).

  Here, when the user performs a selection operation other than the full text search, processing according to the selected content is executed. However, the description is omitted here because it is not directly related to this operation example.

  On the other hand, if it is determined in step S125 that the user has performed a full-text search selection operation, the CPU 21 accepts input of one or more search character strings by the user using the character input key 14a or the transparent touch panel 16t ( Step S126).

  Then, if there is only one search character string input, the search character string is used, and if there are a plurality of search character strings, the search character string is subjected to a full-text search within the content using the search character string as an AND condition. Search is performed (step S127).

  As a result of the search, it is determined whether or not there is a corresponding entry word W or text information T (step S128). If it is determined that there is no corresponding item, an error display to that effect is executed on the color liquid crystal display screen 17d.

  On the other hand, if it is determined in step S128 that there is a corresponding content, the CPU 21 determines whether or not the search is performed by inputting a plurality of character strings in the immediately preceding step S126 (step S129).

  If it is determined that the search is performed by inputting a plurality of character strings, the CPU 21 determines whether or not the input character strings match a registered character string (step S130).

  If there is no registered character string here and it is determined that there is no match as a result, the CPU 21 uses the main search keyword as the first input character string among the plurality of newly input character strings. It is assumed that there is a headline of the learning book (step S132).

  Thereafter, the second and subsequent search keywords are registered in association with the headlines of the learning book (step S133).

  In the case shown in FIG. 5A-2, as described above, “Heian”, “Uji”, and “Byodo-in Temple” are associated and registered as headings constituting one group. Of these, the third character string “Byodo-in Temple” is registered in the “History of Japan” content in advance as an entry word W, and is set by adding an index “xxxx” corresponding to the keyword.

  At this time, on the color liquid crystal display screen 17d, as shown in FIG. 5 (A) -1, text information T corresponding to the third keyword “Beidouinhoudou” is displayed on the color liquid crystal display screen 17d. When other image information and the like are stored in association with the text information T and corresponding to the headword W, the image and the like are also displayed as shown.

  In the text information T displayed on the color liquid crystal display screen 17d, the character string portion matching the input keyword is displayed as a marker as shown in the figure. At this time, for example, the main keyword character string is displayed in a red frame, the second keyword character string is a red marker, the third keyword character string is a yellow marker, and the fourth keyword character string is In addition to displaying with a blue marker, if there is a fifth or subsequent keyword character string, a red marker, a yellow marker, and a blue marker are cyclically assigned and set, and the marker is displayed.

  If it is determined in step S130 that the character string matches the registered character string, the CPU 21 registers the newly input character strings as lower character strings in association with the registered character strings. (Step S131).

  In addition, when it is determined that the user has performed an operation to search from each headword W in the content displayed in step S122, the CPU 21 asks the user to target only the headword W. The user is prompted to input a character string of the search keyword, and accepts the user's character string input in response thereto (step S123). Then, the corresponding entry word W is searched from the input search character string (step S124).

  After the CPU 21 determines that the user has selected to select the main keyword from the table of contents headline in step S102 or after searching for the corresponding headword W using the search character string input by the user in step S124, Alternatively, after determining in step S129 that there is only one character string as a keyword for full text search, or in step S131, a plurality of newly input character strings are associated with registered character strings. After registering as a lower-order character string, or after registering the second and subsequent search keywords in association with the heading of the learning book in step S133, the CPU 21 displays the heading registered at that time as a color liquid crystal display screen. A list is displayed at 17d (step S103).

  From the list of headings, a display prompting the user to select one of the headings is performed, and a selection operation is accepted accordingly (step S104).

  When a headline selection operation is performed, the CPU 21 reads out text information T and the like from the corresponding contents of the dictionary / textbook database 22A as explanatory text for the operated headline, expands it, and displays it on the color liquid crystal display screen 17d ( Step S105).

  Thereafter, it is determined from the output from the transparent touch panel 17t whether or not the marker icon BM in the touch icon area 17B has been touched (step S106).

  If it is determined that the marker icon BM has not been touched, the CPU 21 next determines whether or not a jump search has been designated by selecting the [jump] key KJ in the touch key area 17A by the touch operation. (Step S134).

  If the [jump] key KJ is not selected by the touch operation in step S134 and the jump search is not designated, the process corresponding to the other operation is executed. Description is omitted.

  If it is determined in step S106 that the marker icon BM has been touched, the CPU 21 first automatically sets a red marker (step S107), and the character string being displayed by the user is positioned with the stylus pen. The designation is accepted (step S108).

  Then, the received character string is additionally registered in the learning book of the marker learning book data 22B so as to be a red marker character string associated with the entry word (step S109).

  Thereafter, a display prompting the user to select whether or not to continue the same additional registration processing is performed on the color liquid crystal display screen 17d, and a user's selection operation corresponding to the display is accepted to determine whether or not to continue. (Step S110).

  If it is determined that the additional registration is not continued, the process returns to step S106.

  If it is determined in step S110 that additional registration is to be continued, a yellow marker is automatically set according to the rotation described above (step S111), and the character string being displayed by the user is positioned with the stylus pen. The designation is accepted (step S112).

  Thereafter, it is determined whether or not the user has touched the marker icon BM with the stylus pen to switch the marker color (step S113).

  If it is determined that the marker icon BM has not been touched, the marker learning book data 22B is learned so that the character string received in the immediately preceding step S112 is the yellow marker character string associated with the entry word. It is additionally registered in the book (step S115).

  When it is determined in step S113 that the marker icon BM has been touched, the marker color is changed from “blue” → “red” → “yellow” → “blue” →... After cyclically switching, the character string received in the immediately preceding step S112 is additionally registered in the learning book of the marker learning book data 22B so as to be the marker character string associated with the entry word (step S114).

  In FIG. 5B, the character string “Yodomichi Fujiwara” in the description of the headword “Byodo-in Temple” is set as a yellow marker character string by the user's character string specifying operation with the stylus pen SP. Indicates the state. By this operation, as shown in FIG. 5 (B) -2, the heading “Yujiro Fujiwara” that is adjacent to both the main heading “Uji” and the heading “Byodo-in Temple” is displayed as a blue marker character string. As an additional registration.

  After the process of step S114 or S115, a display prompting the user to select whether or not to continue the same additional registration process is performed on the color liquid crystal display screen 17d, and the user's selection operation corresponding to the display is accepted and continued. It is determined whether or not to perform (step S116).

  If it is determined that the additional registration is not continued, the process returns to step S106.

  If it is determined in step S116 that additional registration is to be continued, a blue marker is automatically set according to the rotation described above (step S117), and the character string being displayed by the user is positioned with the stylus pen. The designation is accepted (step S118).

  Thereafter, it is determined whether or not the user has touched the marker icon BM with the stylus pen to switch the marker color (step S119).

  If it is determined that the marker icon BM has not been touched, the character string received in the immediately preceding step S118 is additionally registered in the study book so as to be a blue marker character string associated with the entry word ( Step S121).

  If it is determined in step S119 that the marker icon BM has been touched, the marker color is changed from “red” → “yellow” → “blue” → “red” →... After cyclically switching, the character string received in the immediately preceding step S118 is additionally registered in the learning book of the marker learning book data 22B so as to be the marker character string associated with the entry word (step S120).

  In FIG. 5 (B) -1, the character string “Amitabido” in the description of the headword “Byodo-in Temple” is set as a blue marker character string by the user's character string designation operation with the stylus pen SP. It shows the state. By this operation, as shown in FIG. 5 (B) -2, a new heading “Amita” adjacent to both the main heading “Uji” and the heading “Byodo-in Temple” is displayed as a blue marker character string. To be added and registered in the marker learning book data 22B.

  After the process of step S120 or S121, the process returns to step S106.

  If it is determined in step S134 that the [jump] key KJ in the touch key area 17A is selected by a touch operation and jump search is designated, the CPU 21 next performs a character string for performing a jump search from the displayed explanatory text. Is designated by the input from the transparent touch panel 17t (step S135).

  When the search character string is designated by the user, the CPU 21 then prompts the user to select a dictionary / textbook content to be searched, and the user performs a dictionary / textbook content selection operation accordingly. Accept (step S136).

  The CPU 21 searches the corresponding contents in the dictionary / textbook database 22A in full text according to the accepted dictionary / textbook content name, and displays a list of all headline candidates including the corresponding search character string on the color liquid crystal display screen 17d (step S137). ).

  The CPU 21 prompts the user to select one of the headings from the list display, and accepts that the user performs a selection operation on it (step S138).

  The CPU 21 that has accepted the user's selection determines whether or not the corresponding heading is the content registered in the learning book of the original marker learning book data 22B (step S139).

  Here, only when the CPU 21 determines that the selected heading has been registered in the original study book, the CPU 21 sets the jump destination heading in association with the original heading in order to expand the contents of the original study book. It is additionally registered as a display with the marker color set at the time (step S140).

  FIG. 5 (C) -1 performs a jump search using the character string “Michicho Fujiwara” in the explanatory text of the headword “Byodo-in Temple” in the display state of FIG. The case where additional heading is registered is shown. Here, it is assumed that “Regent” and “Fujiwara Michichou” are sequentially designated as marker character strings in the description of the heading “Michicho Fujiwara”.

  As a result, as shown in FIG. 5 (C) -2, as the heading further following the main heading “Uji”, a new heading “Regent” is displayed as a red marker character string, and the heading “Michicho Fujiwara” is displayed in yellow. Each is additionally registered as a marker character string. In particular, for the headline “Michicho Fujiwara”, an index “yyyyyy” is set because text information T and the like having this as a headword are present in the content.

  The jump search process corresponding to the operation of the [jump] key KJ in the touch key area 17A is thus completed, and the process returns to the process from step S105.

  In this way, by using the jump search function, the contents of the learning book can be expanded by updating and registering the headings included in the original learning book stored in the marker learning book data 22B as needed by a simpler operation.

Next, display processing using the learning book registered as described above will be described.
FIG. 6 illustrates an operation when one group is selected and displayed from the memorization learning book registered in the marker learning book data 22B in advance.

  Here, as shown in FIG. 7, the main heading is “Peace”, and the relationship of one group of headings in a study book in which a plurality of headings are associated is illustrated. In the present embodiment, the color liquid crystal display screen 17d is divided into a total of nine squares of 3 × 3 and each heading is displayed. This figure exemplifies the positional relationship of the headings when the display is performed.

  In the process of FIG. 6, first, the user is prompted to select one of a plurality of maximum 6 groups (Gr.) “A” to “F” of the learning books registered in the marker learning book data 22B. When the user performs an operation to select any group accordingly, the operation input is accepted (step S301).

  FIG. 8 shows one of the “memorization study books” displayed on the touch panel type color display (main screen) 17 at this time, and three groups registered in the “memorization study book A” registered for the Japanese history of social studies. “A. Viewed last time”, “B. Heian” and “C. Sengoku warlord” are shown together with the check boxes CB.

  In the figure, a check mark “L” is entered in the check box CB of the third group “C. Sengoku warlord”, so that it can be visually confirmed that the group has already been learned. In addition, a state where the second group “B. Heian” is identified and displayed by the color marker in a state where it is temporarily selected is shown. Since it is the second group here, it is displayed with a yellow color marker as in the order of the color markers described above.

  When the user operates the [translation / decision] key KE of the touch key area 17A (or the [translation / decision] key 14c of the key input unit 14) from the state shown in FIG. 8, the CPU 21 accepts it in step S301, Instead of the display screen shown in FIG. 8, a list of headings in the corresponding group is displayed (step S302).

  Here, as described above, the seven headings constituting this group are displayed in a list so as to be listed along the vertical direction of the screen on the color liquid crystal display screen 17d.

  From this headline list display state, it is determined whether or not the marker icon BM in the touch icon area 17B has been operated in order to hide the headline for each marker color (step S303).

  If it is determined that the marker icon BM has not been operated, it is determined whether or not the cursor key (↑, ↓) 14e or the [Translation / Determination] key KE, 14c has been operated to select a heading. (Step S305).

  If it is determined that the key operation for selecting the heading has not been performed, the CPU 21 executes processing corresponding to the other operation, but the description thereof is omitted because it is not related to the present embodiment.

  If it is determined in step S303 that the marker icon BM has been operated, the CPU 21 corresponds to the color marker hiding state set at that time, and “all hidden” → “all displayed” → “ “Hidden Red” → “Yellow Hidden” → “Blue Hidden” → “Fully Hidden” → “Hide all color marker headings”, “Display all color marker headings” ”,“ Hide the red color marker heading ”,“ hide the yellow color marker heading ”, and“ hide the blue color marker heading ”cyclically one step at a time (Step S304), the process returns to step S303 in preparation for further operation of the marker icon BM.

  If it is determined in step S305 that an operation by the user for selecting a headline has been performed, the CPU 21 displays the color liquid crystal display screen 17d on a total of nine squares 3 × 3 × 3 in response to the operation. The main heading is divided and displayed so as to be arranged in the middle cell in the middle (step S306).

  FIG. 9A shows a display example when the [translation / decision] key KE or 14c is operated from the display state shown in FIG. In FIG. 9A, a symbol “X” indicating that the marker icon BM is selected and operated in a state of “hide all” is displayed in the icon.

  Further, the main heading “Peace” is displayed in the middle of the middle of the nine squares by the process of step S306.

  At the same time, in the surrounding squares other than the center of the middle stage, the character string associated with each heading is expressed in the corresponding marker color and displayed in color (step S307).

  In addition, according to the hidden state by the operation of steps S303 and S304, the character string of the headline corresponding to the marker color is hidden and displayed only with the marker color (step S308), while the headline set as learned. Is displayed (step S309).

  In FIG. 9A, the other headings registered in relation to the main heading “Peace”, specifically the right side of the middle stage, the left side of the lower stage, the center of the same stage, and the squares on the right side of the same stage. The eyes are displayed only with the corresponding marker colors as described in FIG.

  Thereafter, it is determined whether or not the cursor key (↑, ↓, ←, ↑) 14e has been operated by the user (step S310). If the cursor key 14e has not been operated, it is further determined whether or not the [translation / decision] key KE or 14c has been operated (step S312).

  When it is determined that there is no operation of the [Translation / Determination] key KE or 14c, it is assumed that there is no operation related to the heading in the same group or that the operation has ended, and the [Return / List] key KR or 14d is used to return the display form. It is determined whether or not an operation has been performed (step S313).

  If it is determined here that a key operation other than the [RETURN / LIST] key KR or 14d has been performed, the CPU 21 executes a process corresponding to the other operation, but the description thereof is omitted as it is not related to the present embodiment. .

  If it is determined in step S313 that the [return / list] key KR or 14d has been operated, the CPU 21 returns to the processing from step S303 according to the key operation.

  When the cursor (↓) key 14e indicating the downward movement of the display range from the display state of FIG. 9A is operated by the user, the CPU 21 determines that in step S305 and determines the character string at the center. In addition to changing according to the operated contents of the cursor key, the character string associated with each heading is displayed in color in the corresponding marker color in the surrounding squares other than the center of the middle stage (step) S311), the process returns to step S310 again.

  FIG. 9B illustrates contents displayed on the color liquid crystal display screen 17d at this time. As shown in the figure, a grid of red markers located under the main heading “Heian” is arranged at the center of the middle stage. Accordingly, the main heading “Heian” moves to the center of the upper stage, and the other squares of the marker colors that conceal the character strings also move upward by one stage.

  Further, when the cursor (↓, ←) key 14e indicating the movement of the downward and leftward display ranges from the display state of FIG. 9B is continuously operated by the user, the process of step S311 is performed twice. By repeatedly executing, the contents displayed on the color liquid crystal display screen 17d are as shown in FIG.

  In FIG. 9C, a cell without a character having only a blue marker corresponding to the heading “Byodo-in Temple” is arranged at the center of the middle stage. A total of five squares on the upper left side, the middle left side, and the lower side are displayed in white, with no corresponding headline and marker color for color display set.

  When the [translation / decision] key KE or 14c is operated by the user from the display state of FIG. 9C, the CPU 21 determines this in step S312, and at that time, the heading corresponding to the square in the center of the screen. Text information T corresponding to the character string is displayed on the color liquid crystal display screen 17d with a color marker (step S314).

  Next, immediately before the [Translation / Determination] key operation in the above description, the character string portion of the heading corresponding to the square at the center of the screen is identified by being surrounded by a double frame (step S315).

  Thereafter, according to the hidden state set at that time, the character string portion of the specified marker color is hidden and displayed (step S317), while the character string of the heading set as learned has been obtained. It is displayed (step S318).

  FIG. 10A shows a display state when the [translation / decision] key KE or 14c is operated by the user from the display state of FIG. 9C. Here, when the [Translation / Determination] key KE or 14c is operated in a state in which the square without the characters of only the blue marker corresponding to the original heading “Byodo-in Temple” is arranged at the center, this heading is operated. Therefore, the text information T and the like corresponding to the headword W “Byodo-in Temple” is hidden and displayed only by the marker display according to the hidden state.

  In this way, it is determined whether or not the [translation / decision] key KE or 14c is operated while displaying the character string of the corresponding color marker portion in accordance with the hidden state (step S319). If it is determined that the [Translation / Determination] key KE or 14c is operated, the hidden character string is temporarily displayed, for example, for 2 seconds (step S320), and then the process of step S319 is performed again. Return to.

  FIG. 10B shows a temporary display state when the [translation / decision] key KE or 14c is operated from the display state of FIG. 10A. In the explanatory text corresponding to the text information T as shown in FIG. 10B, the character string of the headline hidden in the display state of FIG. 10A is temporarily displayed at the corresponding marker portion.

  If it is determined in step S319 that the [translation / decision] key KE or 14c is not operated, the CPU 21 determines whether or not the learning of the currently hidden headline character string has been completed. Judgment is made by the presence or absence of the operation (step S321).

  Here, when learning of the character string of the heading currently hidden has not been completed and it is determined that there is no operation of the “learned” icon BF, the CPU 21 returns [return / list] to return the display form. It is determined whether or not the key KR or 14d has been operated (step S323).

  If it is determined here that a key operation other than the [RETURN / LIST] key KR or 14d has been performed, the CPU 21 executes a process corresponding to the other operation, but the description thereof is omitted as it is not related to the present embodiment. .

  If it is determined in step S323 that the [return / list] key KR or 14d has been operated, the CPU 21 returns to the processing from step S310 according to the key operation.

  FIG. 10C shows the transition state of the display when the user operates the “learned” icon BF from the display state of FIG. 10B and then operates the [return / list] key KR or 14d. Indicates.

  First, when the “learned” icon BF is operated, the CPU 21 determines this in step S321, and at that time, the character string of the corresponding heading, in this case “Beidouinhoudou (Byodo-in Temple)” is displayed. After setting the learned character string and displaying the character string from the state where the character string has been hidden only by the color marker until then (step S322), the process returns to step S319.

  In response to the subsequent operation of the [Return / List] key KR or 14d, the CPU 21 returns to the processing from Step S310. Therefore, on the color liquid crystal display screen 17d, the character string “Byodo-in Temple” is displayed together with the square represented by the blue marker at the center, as compared with the display state shown in FIG. 9C. .

  When the cursor (↑, →) key 14e indicating the movement of the upward and rightward display ranges is continuously operated by the user from the display state of FIG. 10C, the process of step S311 is performed twice. By repeatedly executing, the content displayed on the color liquid crystal display screen 17d is as shown in FIG.

  In FIG. 11A, a square without a character of only a red marker corresponding to the headline “Uji” is arranged in the center. A total of three squares on the upper left side, the middle right side, and the lower right side are displayed in white, with no corresponding headline and marker color for color display being set.

  When the [translation / decision] key KE or 14c is operated by the user from the display state shown in FIG. 11A, the CPU 21 determines this in step S312 and corresponds to the square at the center of the screen at that time. Text information T corresponding to the character string of the heading to be displayed is displayed on the color liquid crystal display screen 17d with a color marker (step S314).

  In this case, there is no index information corresponding to the headline “Uji”, and text information T and the like corresponding to “Uji” as the headword W cannot be displayed. Therefore, the display on the color liquid crystal display screen 17d is performed again using the text information T and the like corresponding to the headword W “Byodo-in Temple” including the heading “Uji” in the same group.

  FIG. 11B shows a display state on the color liquid crystal display screen 17d at this time. In this case, the headings other than the main heading “Heian” and the heading “Beiinho Houdo (Byodo-in Temple)” set as learned by the processing in steps S314 to S318 are based on the set color. The character string is not displayed only by the color marker, and the character string portion of the heading “Uji” selected at this time is displayed in a double frame by the process of step S315.

  When the user further operates the [translation / decision] key KE or 14c as shown in FIG. 11C from this display state, the CPU 21 determines that in step S319 and then hides it in the process in step S320. The character string is displayed temporarily, for example, for only 2 seconds.

  FIG. 12 shows a display transition state when the user operates the “learned” icon BF from the display state of FIG. 11C and then operates the [return / list] key KR or 14d.

  First, when the “learned” icon BF is operated, the CPU 21 determines that in step S321, and sets the character string of the corresponding heading at that time, in this case “Uji”, as learned. Then, after displaying the character string from the state where the character string has been hidden only by the color marker until then (step S322), the process returns to the process from step S319.

  In response to the subsequent operation of the [Return / List] key KR or 14d, the CPU 21 returns to the processing from Step S310. Therefore, on the color liquid crystal display screen 17d, compared with the display state shown in FIG. 11A, the character string “Uji” is also displayed on the front cell with the red marker at the center.

  As explained in detail above, since it is possible to make a learned setting for each of a plurality of associated headings in consideration of the presence or absence of learning, each heading is not a single but a systematic series of flows. Based on this, a large number of items can be learned efficiently.

[Second operation example]
Next, a second operation example of the above embodiment will be described.
In this operation example, after selecting the dictionary / textbook content and displaying the text information T corresponding to the headword W, the character string of the headline to be associated from the sentence is sequentially registered in the marker learning book data 22B. The character string of the registered associated heading is displayed and learned.

  In the registration process of FIG. 3 and FIG. 4 described above, for example, “Social: History of Japan” is selected (step S101), and instead of searching from the table of contents heading (step S102), the user inputs a character string. The headword W to be searched is searched (step S122).

  Here, for example, a character string “Sho Tokutai” is input by an operation at the key input unit 14 or the handwriting input unit 16 (step S123), and a search for a headword W corresponding to the input search character string is executed (step S123). S124).

  Then, a list of headwords W obtained as a result of the search is displayed (step S103). When the user selects “Taiko Shotoku” from the list display, the text information T corresponding to the headword W is described as a touch panel type. The image is displayed on a color display unit (main screen) 17.

  FIG. 13A shows the contents of the text information T corresponding to the headword W “Taiko Shotoku” displayed on the touch panel type color display section (main screen) 17 at this time.

  Here, when the user touches the marker icon BM in the touch icon area 17B of the touch panel type color display unit (main screen) 17, the CPU 21 determines that in step S106, and first selects a red marker according to a predetermined order. It sets (step S107).

  FIG. 13B shows a state in which the user has marked the character string “Emperor Suiko” in the above description using the stylus pen SP by the set red marker function. When the user operates the “registration” icon BRG in the touch icon area 17B after the marking, the CPU 21 receives an instruction for marking and registration of the character string (step S108). Then, the CPU 21 registers the designated marker character string “Eiko Emperor” in the study book in association with the headword W “Taiko Seiko” as the main headline (step S109).

  Thereafter, a display prompting the user to select whether or not to continue the same registration process is performed on the color liquid crystal display screen 17d, and the user's selection operation corresponding to the display is accepted to determine whether or not to continue ( Step S110).

  If it is determined that the registration is to be continued, a yellow marker is automatically set according to the rotation described above (step S111), and the character string being displayed by the user is specified by the stylus pen SP. (Step S112).

FIG. 14A shows a state in which the user has marked the character string “Residence” in the above description using the stylus pen SP by the set yellow marker function.
Thereafter, as shown in FIG. 14B, when the user touches the character string “Emperor Suiko” registered before that with the stylus pen SP, the CPU 21 touches another marker character string. It is determined that there was (step S113), and the character string “Sessho” is registered in the learning book in the marker learning book data 22B in association with the touched marker character string “Emperor Suiko” (step S113). S114).

  Thereafter, a display prompting the user to select whether or not to continue the same additional registration processing is performed on the color liquid crystal display screen 17d, and a user's selection operation corresponding to the display is accepted to determine whether or not to continue. (Step S116).

  If it is determined that the additional registration is not continued, the process returns to step S106.

  In this state, the marker character string “Emperor Suiko” is registered in association with the main index character string “Saintoku Prince”, which is also the headword W, and the marker character string “Emperor Suiko” is registered. In addition, a marker character string “Sessho” is associated and registered.

  As described above, the dictionary / textbook content stored in the dictionary / textbook database 22A is selected, the marker character string is sequentially designated as the headline from the explanatory text corresponding to the headword W in the dictionary / textbook database 22A, and the headline to be associated is selected. By selecting, a learning book can be registered in the marker learning book data 22B.

Next, display processing using the learning book registered as described above will be described.
Here, as shown in FIG. 15A, a case will be described in which the main heading is “Taiko Seiko” and the contents are displayed for one group in a study book associated with a plurality of headings.

  In the process of FIG. 6, first, the user is prompted to select one of a plurality of study book groups (Gr.) “A” to “F” registered in the marker study book data 22B. When the user performs an operation for selecting one of the groups, the operation input is accepted (step S301).

  FIG. 15A is registered in one of the “memorization study books” displayed on the touch panel type color display unit (main screen) 17 at this time, “memorization study book A” registered for Japanese history of social studies. The four groups “A. Viewed last time”, “B. Heian”, “C. Sengoku warlords”, and “D. Shotoku Taiko” are listed together with the check boxes CB.

  In the figure, a check mark “L” is entered in the check box CB of the second group “B. Heian” and the third group “C. Sengoku warlord”, and these groups have already been learned. Is visible. In addition, a state in which the fourth group “D. Shotoku Taiko” is selected and displayed by the color marker in a state where the fourth group “D. Seitoku Taiko” is temporarily selected by the continuous operation of the downward cursor key (↓) 14e.

  Here, the marker icon BM in the touch icon area 17B is touch-operated to be in the “non-hidden display” state, while the “translation / decision” key KE (or the touch key area 17A) from the state shown in FIG. When the user operates the [translation / determination] key 14c) of the key input unit 14, the CPU 21 accepts it in the above step S301 and replaces the display screen shown in FIG. 15A with the headings in the corresponding group. Is displayed (step S302).

  At this time, as described above, the three headlines “Taiko Seitoku”, “Emperor Suiko”, and “Residence” are listed on the color liquid crystal display screen 17d along the vertical direction of the screen. To list.

  When the user further operates the [translation / determination] key KE (or the [translation / determination] key 14c of the key input unit 14) in the touch key area 17A from the heading list display state, the CPU 21 executes step S303. In step S305, the color liquid crystal display screen 17d is divided into a total of nine squares (3 × 3) instead of the display screen shown in FIG. Are arranged so as to be arranged in the middle square in the middle (step S306).

  FIG. 15B shows a display example when the [translation / decision] key KE or 14c is operated twice in succession from the display state shown in FIG. 15A. In FIG. 4B, the main heading “Taiko Seitoku” is displayed at the center of the nine squares. At the same time, in the surrounding squares other than the center, the heading “Suiko Emperor” is displayed in the corresponding red marker color in the lower central square (step S307).

  In addition, according to the hidden state by the operation of steps S303 and S304, the character string of the headline corresponding to the marker color is hidden and displayed only with the marker color (step S308), while the headline set as learned. Is displayed (step S309).

  Here, since the hidden state is “display all”, there is no grid that hides the character string of the heading in step S308, and the processing in step S309 is also unnecessary.

  Thereafter, when the cursor key (↓) 14e for instructing the downward movement of the display range is operated by the user, the CPU 21 determines that in step S310, and the character string in the middle square is operated by the cursor key. The character string associated with each heading is displayed in color with the corresponding marker color at the surrounding squares other than the middle of the middle row and displayed in color (step S311), and then the above steps again. The process returns to S310.

  FIG. 15C illustrates the contents displayed on the color liquid crystal display screen 17d at this time. As shown in the drawing, a red marker headline “Emperor Suiko” located under the main heading “Seioku Taiko” is placed in the middle square.

  Accordingly, the main heading “Heian” is moved to the upper central cell, and the yellow marker heading “Residence” is arranged in the lower central cell.

  In this way, by arbitrarily registering an arbitrary character string in the text information T in association with any headword W of the content, an original learning book in which those character strings are associated is created and learned. can do.

  As described in detail above, according to the present embodiment including the first operation example and the second operation example, by registering a plurality of character strings as keywords as a structure associated with each other, a word to be memorized and learned can be obtained. Rather than simply recording, systematic learning can be realized by visually expressing them as having a systematic connection, thereby contributing to efficient and meaningful learning.

  In the first operation example described above, the full text search of the contents of the dictionary / textbook database is performed using the input character string as a search keyword, and the corresponding headword or explanatory text is displayed, whereby additional registration of the headline character string is performed. Therefore, it is possible to easily search and register related headlines, and to further enhance the learning effect.

  On the other hand, in the second operation example, after selecting the headword W, an arbitrary character string can be easily set from the text information T of the explanatory text, and can be associated and registered as needed. It is suitable for intensive learning of matters related to W, and can contribute to deeper learning with simple operations.

  In addition, in the second operation example, when specifying the second and subsequent character strings in the description, it is possible to set other character strings to associate the character strings instead of the head word W. By carefully considering the association, the learning effect can be further enhanced.

  Furthermore, in the above first and second operation examples, the character string of each heading is registered by setting the marker color of the background portion of the character string to be sequentially changed according to the registration order of the heading, and any marker color is set. Since the display / non-display of the character string can be switched according to the situation, the adjacent character strings do not have the same color as much as possible, and the individual character strings can be divided and displayed in an identifiable manner. Thus, the switching operation when learning each headline can be simplified.

  In addition, in the above operation example, in order to display all the marker color heading character strings, the hidden state is set to “display without hiding”, or the [translation / decision] key 14c or KE is operated. Since the character string portion hidden in can be displayed, the learning result can be confirmed by a simple operation, and the usability can be improved.

  Note that the methods described in the flowcharts of FIGS. 3 and 4 and FIG. 6 of the above-described embodiment are memory cards, magnetic disks (floppy disk (registered trademark) devices, and hard disk devices) as programs that can be executed by a computer. ), An optical disk (CD-ROM, MO disk, DVD, etc.), an external storage medium such as a semiconductor nonvolatile memory, and the like can be distributed.
