  In this item content display processing, as shown in FIG. 5, the CPU 20 first reads the text of the item to be displayed (hereinafter referred to as display target text) selected by the user and displays it on the main display 10 (step S1). ).

At this time, when the position information of the marker display character string (the start position and the end position of the marker display character string in the text) is stored in the marker information database 85 for the item of the display target text, the CPU 20 The character string of the position information is displayed as a marker in the marker color associated with the item. Further, at this time, the CPU 20 associates the marker display character string associated with the position information (dictionary database name, headword) of the link destination text with the position information of the link destination text in the marker information database 85. Different marker display character strings are identified and displayed in a different manner. In this embodiment, the marker display character string associated with the position information of the link destination text is described as being identified and displayed in bold. However, the marker display character string may be identified and displayed with colored characters. Identification display may be performed by changing the color density. Moreover, it is good also as identifying the marker display character string with which the positional information on a link destination text is not matched.
Further, at this time, the CPU 20 displays the marker icon 101 and the link marker icon 102 (see FIG. 9A) on the end of the main display 10.

Here, the marker icon 101 receives a start operation of a normal marker mode process (step S3) described later.
In addition, the link marker icon 102 receives a start operation of a link marker mode process (step S5) described later.

  Next, the CPU 20 determines whether or not a touch operation is performed on the marker icon 101 (step S2). If it is determined that the touch operation is not performed (step S2; No), the process proceeds to step S4 described later.

  If it is determined in step S2 that a touch operation has been performed on the marker icon 101 (step S2; Yes), the CPU 20 performs normal marker mode processing (step S3).

  Specifically, as shown in FIG. 6, in this normal marker mode process, the CPU 20 first displays the registration icon 103, the pen icon 104, the color selection icon 105, and the eraser icon 106 (see FIG. 9B) on the main display 10. And a determination is made as to whether or not a touch operation is performed on the registered icon 103 (step T1).

Here, the registration icon 103 is configured to receive an operation for registering information about the marker display character string.
The pen icon 104 is configured to receive a marker display character string designation start operation.
The color selection icon 105 is subjected to a marker color switching operation of the marker display character string, and is displayed in the same color as the marker color in this embodiment.
In addition, the eraser icon 106 receives an operation for canceling designation of a marker display character string.

  When it is determined in this step T1 that the touch operation is not performed on the registered icon 103 (step T1; No), the CPU 20 determines whether or not the touch operation is performed on the color selection icon 105. (Step T2).

  If it is determined in step T2 that the touch operation has been performed on the color selection icon 105 (step T2; Yes), the CPU 20 changes the display color of the color selection icon 105, that is, the marker color of the marker display character string. (Step T3), the process proceeds to Step T1 described above. In this embodiment, every time the CPU 20 determines that a touch operation has been performed on the color selection icon 105, the display color of the color selection icon 105 is changed in the order of red, yellow, blue, and red. ing.

  When it is determined in step T2 that the touch operation is not performed on the color selection icon 105 (step T2; No), the CPU 20 determines whether or not the touch operation is performed on the pen icon 104. (Step T4).

  If it is determined in step T4 that a touch operation has been performed on the pen icon 104 (step T4; Yes), the CPU 20 accepts a range specifying operation for a character string in the display target text (step T5). After the designated character string is displayed as a marker display character string in the display color of the color selection icon 105 (step T6), the process proceeds to step T1 described above.

  When it is determined in step T4 that the touch operation is not performed on the pen icon 104 (step T4; No), the CPU 20 determines whether or not the touch operation is performed on the eraser icon 106. (Step T7) When it is determined not to be performed (Step T7; No), the process proceeds to Step T1 described above.

  If it is determined in step T7 that a touch operation has been performed on the eraser icon 106 (step T7; Yes), the CPU 20 accepts a touch operation on the marker display character string (step T8).

  Next, the CPU 20 cancels the marker display for the marker display character string on which the touch operation is performed and switches to the normal display (step T9), and then proceeds to the above-described step T1.

  If it is determined in step T1 that the touch operation has been performed on the registered icon 103 (step T1; Yes), the CPU 20 determines the content name, item type, and item name of the display target text. Correspondingly stored and stored in the word book database 86 as position information of the link source text, the position information (start position, end position) of the marker display character string in the text and the marker color are associated with each other to be displayed. The contents and items of text are accumulated and stored in the marker information database 85 (step T10), and the normal marker mode process is terminated. In the present embodiment, a description will be given assuming that the touch operation is performed on the registered icon 103 after the processing of steps T5 to T6 described above is performed. In the present embodiment, the CPU 20 will be described as not storing new position information when the position information of the same link source text is already stored in the word book database 86.

  When the above normal marker mode processing is completed, as shown in FIG. 5, the CPU 20 next displays the marker icon 101 and the link marker icon 102 on the end of the main display 10 and touches the link marker icon 102. It is determined whether or not the operation is performed (step S4), and when it is determined that the operation is not performed (step S4; No), the process proceeds to step S6 described later.

  If it is determined in step S4 that a touch operation has been performed on the link marker icon 102 (step S4; Yes), the CPU 20 performs link marker mode processing (step S5).

  Specifically, as shown in FIG. 7, in this link marker mode process, the CPU 20 first displays the registration icon 103, the pen icon 104, the color selection icon 105, and the eraser icon 106 on the end of the main display 10, It is determined whether or not a touch operation is performed on the registered icon 103 (step U1).

  When it is determined in step U1 that the touch operation is not performed on the registered icon 103 (step U1; No), the CPU 20 determines whether or not the touch operation is performed on the color selection icon 105. (Step U2).

  If it is determined in step U2 that a touch operation has been performed on the color selection icon 105 (step U2; Yes), the CPU 20 changes the display color of the color selection icon 105 (step U3), and then the above-described operation. The process proceeds to step U1. In the present embodiment, the CPU 20 switches and changes the display color of the color selection icon 105 in the order of red, yellow, blue, and red.

  When it is determined in step U2 that the touch operation is not performed on the color selection icon 105 (step U2; No), the CPU 20 determines whether or not the touch operation is performed on the pen icon 104. (Step U4).

  If it is determined in step U4 that a touch operation has been performed on the pen icon 104 (step U4; Yes), the CPU 20 accepts a range designation operation for a character string in the display target text (step U5). The designated character string is displayed as a marker in the display color of the color selection icon 105 (step U6).

  Next, the CPU 20 divides the display area of the main display 10 into upper and lower parts, and then continuously displays the display target text as the link source text in the upper display area, and the link destination text to be linked to the current display item. A search screen for searching is displayed in the lower display area (step U61). In the present embodiment, the search screen displayed in step U61 includes Japanese and English input fields 107 (see FIG. 9C).

  Next, after receiving the input of the search character string in Japanese or English from the user, the CPU 20 searches the dictionary database 90 corresponding to the input character type for a headword corresponding to the search character string, and sets the search result as the main. It is displayed on the lower display area of the display 10 (step U62). More specifically, in step U62, the CPU 20 further divides the lower display area on the main display 10 into left and right after inputting the search character string, and displays a list of searched headwords in the lower left display area. The headword is selected with the cursor, and the explanation information of the selected headword is read from the corresponding dictionary database 90 and previewed in the lower right display area. At this time, the user can select a headword using the cursor key 2e.

  Next, based on whether or not the translation / decision key 2b is operated, the CPU 20 determines whether or not a headword of the description information text to be registered as a link destination is specified (step U63). If it is determined not to be performed (step U63; No), the process proceeds to step U61 described above.

  If it is determined in step U63 that the translation / decision key 2b has been operated (step U63; Yes), that is, if it is determined that the headword of the description information text to be registered as the link destination is specified, the CPU 20 The description information text of the headword is displayed as a link destination text in the lower display area of the main display 10 and the position information (dictionary database name, headword) of the link destination text is stored in the link destination information database 87. (Step U64), the process proceeds to Step U1 described above.

  When it is determined in step U4 that the touch operation is not performed on the pen icon 104 (step U4; No), the CPU 20 determines whether or not the touch operation is performed on the eraser icon 106. (Step U7) If it is determined not to be performed (Step U7; No), the process proceeds to Step U1 described above.

  If it is determined in step U7 that a touch operation has been performed on the eraser icon 106 (step U7; Yes), the CPU 20 accepts a touch operation on the marker display character string (step U8).

  Next, the CPU 20 cancels the marker display for the marker display character string on which the touch operation is performed and switches to the normal display (step U9), and then proceeds to the above-described step U1.

  If it is determined in step U1 that the touch operation has been performed on the registered icon 103 (step U1; Yes), the CPU 20 displays the display target text (in the upper display area of the main display 10). (Link source text) content name, item type, and item name are associated and stored in the word book database 86 as position information of the link source text, and the position of the marker display character string in the text Marker information about contents and items of display target text by associating information (start position, end position), marker color, and position information (dictionary database name, headword) of link destination text with respect to the marker display character string Accumulated and stored in the database 85 (step U10). Further, at this time, the CPU 20 sets the marker display character string associated with the position information of the link destination text in the marker information database 85 to be different from the marker display character string not associated with the position information of the link destination text. To identify and display. In the present embodiment, description will be made assuming that the touch operation is performed on the registration icon 103 after the processing of the above steps U61 to U64 is performed. In the present embodiment, the CPU 20 will be described as not storing new position information when the position information of the same link source text is already stored in the word book database 86.

  The CPU 20 then links the position information (dictionary database name, headword) of the link destination text registered in step U64 described above in association with the registration number in the word book database 86 for the link source item. After the information is stored in the destination information database 87 (step U11), the display target text, that is, the link source text is continuously displayed on the main display 10 and the link marker mode process is terminated.

  When the above link marker mode processing is completed, as shown in FIG. 5, the CPU 20 next determines whether or not any displayed marker display character string is designated by a touch operation (step S6). . When a marker display character string is designated by a touch operation, the CPU 20 determines whether a marker display character string to be designated (hereinafter referred to as a designated marker display character string) is a normal marker process or a link marker process. Determine if a marker is displayed. At this time, the CPU 20 determines the character string based on whether or not the position information of the linked text in the marker information database 85 is associated with the position information of the marker display character string on which the touch operation is performed. Determines whether the marker is displayed by normal marker processing or link marker processing.

  When it is determined in step S6 that no marker display character string is designated, that is, when it is determined that no touch operation is performed on any marker display character string (step S6; No), the CPU 20 displays the item content display. The process ends.

  If it is determined in step S6 that the marker display character string has been designated, and if it is determined that the designated marker display character string has been displayed by the normal marker processing (step S6; Yes, normal marker) ), The CPU 20 proceeds to the above-described step U61 as shown in FIG. Thus, when a marker display character string that is not associated with the position information of the link destination text in the marker information database 85 is designated as the designated marker display character string, any dictionary database 90 in the content group 9 is used. The description information text of one of the headwords is designated as the link destination text for the marker display character string.

  Also, as shown in FIG. 5, when it is determined in step S6 that a marker display character string has been specified, and when it is determined that the specified marker display character string is displayed as a marker by link marker processing ( In step S6; Yes, link marker), the CPU 20 associates the specified marker display character string information (such as the start position and end position of the marker display character string in the text) in the marker information database 85. Based on the position information (dictionary database name, headword) of the link destination text, the link destination text (headword explanation information text) for the character string is detected and displayed on the main display 10 in full screen (step S7), the item content display process is terminated. However, after step S7, the CPU 20 may shift to the above-described step S1 without ending the item content display process.

<Marker word book call processing>
FIG. 8 is a flowchart showing the flow of the marker word book calling process in which the CPU 20 reads and executes the information display program 81. The marker word book calling process is executed when the user selects a learning mode from the menu screen via the input unit 30 and performs an activation operation of the marker word book mode. Here, when the marker word book mode activation operation is performed, a menu screen of the marker word book mode is displayed on the main display 10, and on this menu screen, “view marker word book” or “search from link destination” is displayed. Is displayed (see FIG. 12B).

  In this marker word book calling process, first, the CPU 20 determines whether or not the “search from link destination” menu is selected from the menu screen of the marker word book mode (step W1), and determines that it has been selected. In (Step W1; Yes), the position information of the link destination text registered in the link destination information database 87, that is, the combination of the dictionary database name and the headword is displayed in a list on the main display 10 (Step W2), and the dictionary database name is displayed. And a selection operation are received from the user for the combination of the headwords.

  Next, the CPU 20 obtains the information about the link source associated with the selected dictionary database name and headword in the link destination information database 87, that is, the registration number in the word book database 86 for the item of the link source. The position information of the link source text corresponding to this registration number, that is, the combination of the content name, item name, and item type is read from the word book database 86 and displayed in a list on the main display 10 (step W3). A selection operation is received from the user for combinations of item names and item types.

  More specifically, at this time, the CPU 20 divides the display area of the main display 10 into upper and lower parts and displays a list of link source text position information (content name, item name, item type) in the upper display area. Any combination is selected with the cursor, and the selected link source text is read from the content group 9 and displayed in a preview in the lower right display area. At this time, the user can select the link source text with the cursor key 2e.

  Furthermore, at this time, when the position information (start position, end position) of the marker display character string is stored in the marker information database 85 for the link source text item displayed in the preview, the CPU 20 stores the position information. A marker display character string in which the character string is displayed in the marker color associated with the item and the position information (dictionary database name, headword) of the link destination text is associated in the marker information database 85 And the marker display character string not associated with the position information of the link destination text are identified and displayed in a different manner.

  Next, when the user confirms the selection of the link destination text by operating the translation / decision key 2b, the CPU 20 continues to display the selected content name, item name, and item type text on the main display 10 in full screen ( Step W4), the marker word book calling process is terminated. In addition, CPU20 is good also as shifting to above-mentioned step S1 after complete | finishing a marker word book calling process.

  If it is determined in step W1 that the “search from link destination” menu is not selected from the menu screen (step W1; No), the CPU 20 selects the “view marker word book” menu. (Step W5), and if it is determined that it is not selected (Step W5; No), the marker word book calling process is terminated.

  If it is determined in step W5 that the “view marker word book” menu has been selected (step W5; Yes), the CPU 20 stores the position information of the link source text registered in the word book database 86, that is, the content. A combination of name, item name, and item type is displayed in a list on the main display 10 (step W6), and a selection operation is accepted from the user for the content name, item name, and item type.

  More specifically, at this time, the CPU 20 divides the display area of the main display 10 into upper and lower parts, and displays position information of the link source text, that is, a list of combinations of content names, item names, and item types in the upper display area. Then, any combination is selected with the cursor, and the selected link source text is read from the content group 9 and previewed in the lower right display area. At this time, the user can select the link source text with the cursor key 2e.

  Furthermore, at this time, when the position information (start position, end position) of the marker display character string is stored in the marker information database 85 for the link source text item displayed in the preview, the CPU 20 stores the position information. A marker display character string in which the character string is displayed in the marker color associated with the item and the position information (dictionary database name, headword) of the link destination text is associated in the marker information database 85 And the marker display character string not associated with the position information of the link destination text are identified and displayed in a different manner.

  When the user confirms the selection of the link source text by operating the translation / decision key 2b, the CPU 20 continues to display the selected content name, item name, and item type text on the main display 10 in full screen (step). W7) The marker word book calling process is terminated. In addition, CPU20 is good also as shifting to above-mentioned step S1 after complete | finishing a marker word book calling process.
