A specific headword reference function to be displayed in the preview screen area is provided.
In the present embodiment, headwords registered in a word book provided for each dictionary mode (each dictionary) (hereinafter referred to as registered headwords) and headwords searched in the past (hereinafter referred to as history headlines). Is defined as a specific headword.

In describing the specific headword reference function, a registration headword and a history headword registration method defined as specific headwords will be described first.
First, a registered headword registration method, that is, a headword registration method in a word book will be described.
A headword stored in one of the dictionaries in the dictionary data 161 is designated, the determination key 26 is pressed, and the explanation information of the corresponding headword is displayed on the display 30, that is, the headword search program 163. If the user presses the registration key 23 shown in FIG. 2 in the state where the search process is executed, the headword, that is, the headword corresponding to the displayed explanation information is registered in the word book.

Specifically, when the user presses the registration key 23, the CPU 11 detects that the registration key 23 has been operated, and activates the word book registration program 164 stored in the ROM 16.
When the word book registration program 164 is activated, the CPU 11 recognizes the type of dictionary mode currently used and is displayed in the corresponding dictionary mode area allocated to the word book data storage area 172 in the RAM 17. Headwords corresponding to the description information, more specifically, the word number of the headword. Write the data.
In the electronic dictionary 1, when the CPU 11 detects an operation signal of the function key 22 to which the word book reference function is assigned, the registered entry word of the word book corresponding to the currently activated dictionary mode is read from the word book data storage area 172. The display 30 is configured to display.

Next, a method for registering history entry words will be described.
In this embodiment, when the electronic dictionary 1 is powered on, the entry word search program 163 is activated and the history registration program 165 is activated at the same time. When the history registration program 165 is activated, a headword stored in one of the dictionaries in the dictionary data 161 is designated, and when the determination key 26 is pressed, the explanation information of the corresponding headword is displayed on the display 30. The CPU 11 stores a headword corresponding to the explanation information displayed in the history data storage area 173 in the RAM 17, more specifically, the word number of the headword. Write the data.
In the electronic dictionary 1, when the CPU 11 detects an operation signal of the function key 22 to which the history reference function is assigned, the history headword is read from the history data storage area 173 and displayed on the display 30.

Next, a method for setting the type of specific headword for displaying the description information in the preview screen area when using the specific headword reference function, that is, a method for setting a display candidate referred to in the preview screen area will be described.
FIG. 4 is a flowchart showing a procedure for setting a specific headword type for displaying description information in the preview screen area when the specific headword reference function is used.
The type of specific headword indicates the type of dictionary mode of the word book in which the headword that is the target of the specific headword is registered. In the present embodiment, history headwords stored in the history data storage area 173 are also handled as one type of specific headword.
When the comparison target selection key 24 shown in FIG. 2 is pressed by the user, the CPU 11 detects that the comparison target selection key 24 has been operated, and starts the comparison target setting program 166 stored in the ROM 16.

When the comparison target setting program 166 is activated, the CPU 11 displays on the display unit 13 (display 30) a list of selectable comparison target candidates preset in the electronic dictionary 1, that is, a list of specific headword type candidates. (Step 11).
FIG. 5A is a diagram illustrating an example of a list display screen of comparison target candidates (display candidates).
FIG. 5B is a diagram showing an example of a display screen on which a type to which a specific headword to be a reference display target belongs is selected.
A list as shown in FIG. 5A is displayed, and the user is prompted to select the type to which the specific headword to be displayed for reference belongs.
As shown in FIG. 5B, the type can be selected by adding a check mark to a check box provided in each type item.

By operating the cursor key 27, the cursor (area highlighted on the screen) is matched with the type item to be selected, and by pressing the enter key 26 in that state, a check mark is put in the check box of the corresponding type item. Can be attached.
The check mark can be removed by moving the cursor to the type item with a check mark in the check box and pressing the enter key 26 in that state.
Returning to the description of FIG. 4, when the type of the comparison target candidate (display candidate) is selected, that is, when a check mark is added to the check box of the type item and the determination key 26 is pressed, the CPU 11 corresponds. The selection of the type item is accepted, and the accepted setting information is stored in the setting data storage area 174 in the RAM 17 (step 12).
Then, the CPU 11 creates a comparison data table, that is, a list data of specific headwords to be referred to, based on the setting information of the comparison target candidates (display candidates) stored in the setting data storage area 174 (step 13).
The CPU 11 stores the created comparison data table in the setting data storage area 174 in the RAM 17 and then ends the process.

Here, the comparison data table created in step 13 will be described.
FIG. 6 is a diagram illustrating an example of the comparison data table.
The CPU 11 reads out registered headwords and history headwords corresponding to the selected type (dictionary mode) from the word book data storage area 172 and history data storage area 173, and creates a comparison data table as shown in FIG. To do.
In the comparison data table, as shown in FIG. 6, a comparison word (specific headword) and a word number identifying a headword are stored. In addition, the information on the storage location is linked. In the comparison data table, these pieces of information are the word numbers. Sorted in (character code) order.
The comparison word is a word No. registered in the word book data storage area 172. Is obtained by extracting from the dictionary data 161 based on the above.
The storage location indicates an area in which the corresponding comparison word is stored. Specifically, “W” indicates the word book data storage area 172 and “H” indicates the history data storage area 173. . Although not shown, a code for identifying (specifying) the dictionary mode of the corresponding word book is attached to the comparison word stored in the word book data storage area 172 as storage location information.

Next, a search result of the designated headword when the specific headword reference function is used, that is, a method for displaying the explanation information corresponding to the designated headword will be described.
FIG. 7 is a flowchart showing a procedure for displaying a search result of a specified headword when the specific headword reference function is valid.
When the specific headword reference function is set to be valid, the display processing program 167 is activated, and display processing is executed according to this program. In the present embodiment, a description will be given by taking as an example the case of searching for the headword “green tea” in the Japanese dictionary mode.
In any dictionary mode (in this case, the Japanese dictionary mode) set in the electronic dictionary 1, character information of a headword to be searched is input from the input unit 12 of the electronic dictionary 1, that is, the character input key 25. Then, the CPU 11 stores the input character information in the headword data storage area 171 in the RAM 17. That is, the CPU 11 accepts designation of headword data.

Then, the CPU 11 searches the dictionary data 161 for the character string stored in the entry word data storage area 171, that is, the designated entry word, and describes the explanation corresponding to the designated entry word in a predetermined working area in the RAM 17. Reading to the area (step 21).
Next, the CPU 11 reads out the comparison data table created based on the selection condition (setting condition) of the type to which the specific headword to be the reference display target described above belongs from the setting data storage area 174 in the RAM 17 (step 22).
Subsequently, the CPU 11 determines whether or not there is a comparison word stored in the comparison data table, that is, a character string that matches the specific entry word, in the comment character string corresponding to the designated entry word. Is determined (step 23).
Here, the CPU 11 performs a process of extracting a character string that matches the specific headword from a commentary character string corresponding to the designated headword. When a character string that matches the specific headword is extracted from the commentary character string corresponding to the designated headword, it is determined that there is a character string that matches the specific headword.

In other words, the CPU 11 stores the explanation “corresponding to the headword“ Ryokucha [green tea] ”in the comparative data table in the“ tea that has been steamed and dried in a roaster ”. It is determined whether or not a character string that matches the stored comparison word (specific headword) is included.
Here, the CPU 11 first determines whether or not there is a matching character between the first character of the comment character string corresponding to the designated headword and the first character of the character string of the comparison word in the comparison data table. Determine (compare). If there is a matching character, the CPU 11 determines whether or not the character string of the comparison word and the commentary character string corresponding to the designated entry word completely match.
If there is no matching character, the CPU 11 compares the second character of the comment character string corresponding to the specified headword with the first character of the character string of the comparison word in the comparison data table, and the same Continue processing.

If the character string that matches the comparison word (specific head word) stored in the comparison data table does not exist in the comment character string corresponding to the designated head word (step 23; N). The CPU 11 displays the commentary corresponding to the designated entry word in the area of the main screen area displayed on the full screen (step 24), and returns to the main routine.
That is, when there is no specific headword in the comment character string corresponding to the designated headword, the preview screen area is not displayed.

On the other hand, when there is a character string that matches the comparison word (specific headword) stored in the comparison data table in the commentary character string corresponding to the designated headword (step 23; Y). The CPU 11 determines whether or not there are a plurality of matching specific headwords (step 25).
That is, the CPU 11 determines the number of specific headwords that match the character string of the explanation of the designated headword.
When there are not a plurality of specific headwords that match the character string of the description of the specified headword, that is, when only one specific headword matches (step 25; N), the CPU 11 corresponds to the specified headword. The commentary to be displayed is displayed in the main screen area, and the commentary of the matching specific headword is read from the corresponding dictionary data 161 and displayed in the preview screen area (step 26). Then, after displaying the screen, the CPU 11 returns to the main routine.

Here, the display screen displayed by the process of step 26 will be described.
FIG. 8 is a diagram showing an example of a display screen in the case where only the character string for explaining the specified headword matches one specific headword.
For example, if only the character string of the explanation corresponding to the headword “Ryokucha [green tea]” matches one specific headword “Wakaba [Wakaba]”, the display area of the display unit 13 is shown in FIG. As shown, it is divided into two in the vertical direction. Specifically, it is divided into an upper half main screen area and a lower half preview screen area.
Then, the headword “Ryokucha [green tea]” and its explanation are displayed in the main screen area, and the specific headword “Wakaba [Wakaba]” and its explanation are displayed in the preview screen area.

Further, as shown in FIG. 8, only the character string “Wakaba” in the explanation of the headword “Ryokucha [green tea]” displayed in the main screen area is highlighted.
In this way, by highlighting the character string of a specific headword in the explanation displayed in the main screen area, it is easy to distinguish (distinguish) from other character strings in the explanation of the headword. it can. Therefore, the user can easily visually recognize in which part of the explanation displayed in the main screen area the specific headword whose explanation is displayed in the preview screen area exists (appears). be able to.

Returning to the description of FIG. 7, when there are a plurality of specific headwords that match the character string of the description of the designated headword (step 25; Y), the CPU 11 displays the explanation corresponding to the designated headword on the main screen. The description of the specific headword that appears first in the comment character string among the matching specific headwords is read from the corresponding dictionary data 161 and displayed in the preview screen area (step 27).
Here, the display screen displayed by the process of step 27 will be described.
FIG. 9A is a diagram showing an example of a display screen in the case where a character string for explaining a specified headword matches a plurality of specific headwords.
For example, if the explanation string corresponding to the headword “Ryokucha [green tea]” matches multiple specific headwords (“Wakaba [Wakaba]” and “Kanso [Dry]”), the main screen The headline “Ryokucha [green tea]” and its explanation are displayed in the area. Then, the specific headword “Wakaba [Wakaba]” that appears first in the character string of the headword explanation in the main screen area and the explanation thereof are displayed in the preview screen area.

If multiple specific headwords match, all specific headwords appearing in the explanation displayed in the main screen area are displayed with an underline, and the current preview screen area The character string of the specific headword on which the explanation is displayed is highlighted.
In the present embodiment, this highlighted position indicates the position of the cursor on the screen.
By underlining all specific headwords that appear in the commentary displayed in the main screen area, the user can easily determine which part of the commentary contains (appears). Can be visually recognized.
The specific headword identification display is not limited to the underlined display form. For example, the character string of the specific headword may be displayed in a different color.

Returning to the description of FIG. 7, the CPU 11 next determines whether or not the cursor key 27 in the input unit 12 has been operated to move the cursor displayed in the main screen area (step 28). The CPU 11 determines whether or not a cursor movement operation has been performed by detecting an operation signal of the cursor key 27.
In the present embodiment, for example, each time the cursor key 27 indicating the → direction is pressed, the position of the displayed cursor appears behind (in the subsequent stage) in the explanation displayed in the main screen area. It is configured to jump sequentially to a specific headword.
Further, for example, each time the cursor key 27 indicating the ← direction is pressed, the position of the displayed cursor is sequentially shifted to the specific headword appearing in the front (previous stage) in the explanation displayed in the main screen area. Configured to jump.

When the cursor movement operation is not performed (step 28; N), the CPU 11 returns to the main routine while maintaining the current display state.
On the other hand, when the cursor movement operation is performed (step 28; Y), the CPU 11 describes the destination of the cursor displayed in the main screen area, that is, the explanation of the specific headword designated by the cursor, in the corresponding dictionary. The data 161 is read out and displayed in the preview screen area (step 29), and the process returns to step 28 again.

Here, the display screen displayed by the process of step 29 will be described.
FIG. 9B is a diagram showing an example of a character string for explaining a specified headword and a display screen when a cursor movement operation is performed.
For example, as shown in FIG. 9A, the cursor on the character string “Wakaba” in the explanation corresponding to the headword “Ryokucha [green tea]” is changed to the cursor key 27 in the ↓ direction. As shown in FIG. 9B, a case where the character is moved to the position of the character string “dry” appearing next to “young leaf” will be described.
When the position of the cursor moves to the position of the character string “dry”, the specific headword designated by the cursor, that is, “dry” and its explanation are displayed in the preview screen area.
Even when the display content of the preview screen area is changed (updated) in the process of step 29, the explanation corresponding to the specified headword is continuously displayed in the main screen area. However, the place where the cursor exists in the main screen area, that is, the character string “dry” is displayed in reverse video.

In addition, when the cursor is at the position of the character string of the specific headword in the commentary character string displayed in the main screen area, that is, when any character string is designated by the cursor, the enter key 26 is When pressed, the CPU 11 stores the headword specified by the cursor in the headword data storage area 171 in the RAM 17 as a newly input headword, and repeats the process of step 21 again.
For example, as shown in FIG. 9B, when the character string “dry” displayed in the main screen area is designated (instructed) by the cursor, the CPU 11 , “Dry” is recognized as the designated headword.
FIG. 9C is a diagram showing an example of a display screen when the enter key 26 is pressed in a state where the cursor is displayed on the specific entry word.
Then, as shown in FIG. 9C, the headword “Kanso [Dry]” and its explanation are displayed in the main screen area, and the comparison word (stored in the comparison data table) is displayed in the preview screen area. A specific headword “aridity” that matches the specific headword) and a description thereof are displayed.

According to the present embodiment, by using the specific headword reference function as described above, when a specific headword such as a registered headword or a history headword exists in the description of the headword to be searched. The specific headword can be displayed so as to be distinguishable from other character strings (character strings that are not specific headwords).
As a result, it is possible to more appropriately promote understanding of the headwords registered in the word book and headwords searched in the past, so that the convenience of the user using the electronic dictionary 1 can be further improved. .
Also, a search operation (jump operation) to display a description of a specific headword by automatically displaying a description of the specific headword in the description of the headword to be searched in the preview screen area. The user can be made to recognize the explanation of the specific headword without executing the above.

Next, a modification of the above-described embodiment will be described.
(First modification)
In the embodiment described above, a case has been described in which one piece of storage location information is associated with one comparison word (specific headword) in the comparison data table.
Therefore, in the first modification, a case will be described in which information of a plurality of storage locations is associated with one comparison word (specific headword) in the comparison data table.
Here, as an example, in the comparison data table, information of two storage locations of the word dictionary in the Japanese dictionary mode and the word book in the Japanese-English dictionary mode is linked to the specific headword “Wakaba [Wakaba]”. The display process when there is a case will be described. Specifically, the process in step 26 of the flowchart shown in FIG. 7 in such a case will be described.

FIGS. 10A and 10B are examples of display screens when information on a plurality of storage locations is associated with one comparison word (specific headword) in the comparison data table. FIG.
Similarly to the above-described embodiment, when only the character string of the explanation corresponding to the headword “Ryokucha [green tea]” matches one specific headword “Wakaba [Wakaba]”, the headline is displayed in the main screen area. The word “Ryokucha [green tea]” and its explanation are displayed, and the specific headword “Wakaba [Wakaba]” and its explanation are displayed in the preview screen area.
Further, as shown in FIGS. 10A and 10B, the character string “Wakaba” of the specific headword in the main screen area is stored (registered). A number indicating the number of places is attached and displayed.

Specifically, in the character string of the description of the specified headword displayed in the main screen area, a specific headword associated with information of a plurality of storage locations and a character immediately before the specific headword In between, a circled number indicating the number of storage locations of the specific headword is inserted.
It should be noted that the circled numeral display area indicating the number of storage locations is recognized as a part of the specific headword with the circled numeral. Therefore, when the cursor is positioned on this specific headword, the circled numbers are also highlighted in the same manner as the specific headword.

When the information of a plurality of storage locations is linked to the specific headword in the explanation of the designated headword, first, as shown in FIG. 10A, the specific headword is registered. An explanation corresponding to the storage location (word book) having the latest order is displayed in the preview screen area. That is, the word registration numbers are displayed in the preview screen area in descending order.
Subsequently, each time the cursor key 27 indicating the ↓ direction is pressed, an explanation corresponding to the storage location with the next highest registered order is displayed in the preview screen area.
The order in which the explanations of the specific headwords are displayed in the preview screen area is not limited to the order in which the specific headwords are registered, for example, the order in which the specific headwords are registered is late. Alternatively, the display may be made based on the priority order of the type candidates of specific headwords set in advance.
As described above, according to the first modification, even when the same entry word is registered in the word book in a plurality of dictionary modes, the preview screen area can be obtained by simply operating the cursor key 27. In, the explanation in each dictionary mode can be switched and displayed.

(Second modification)
In the above-described embodiment, the method of switching and displaying the explanation of the specific headword displayed in the preview screen area by moving the position of the cursor in the main screen area has been described. It is not limited to this. Therefore, in the second modification, another display method for explaining specific headwords will be described.
If there are a plurality of specific headwords that match the comment string of the specified headword, the CPU 11 displays the commentary corresponding to the specified headword in the main screen area, and displays all the matching specific headwords. The explanation may be displayed by dividing the preview screen area.
For example, if the comment string corresponding to the headword “Ryokucha [green tea]” and two specific headwords (“Wakaba [Wakaba]” and “Kanso [Dry]”) match, the preview screen The area is divided into two in the vertical direction. The specific headword “Wakaba [Wakaba]” and its explanation are displayed in the upper half area of the divided preview screen area, and the specific headword “Kanso [Dry]” and its explanation are displayed in the lower half area. You may make it display.

In addition, such a display method involving the division of the preview screen area is such that information on a plurality of storage locations is linked to a specific headword in the explanation of a specified headword as described in the first modification. It can also be applied when
Specifically, if the specific headword “Wakaba [Wakaba]” is linked to the information in the two storage locations of the word dictionary in the Japanese dictionary mode and the word book in the Japanese-English dictionary mode, the preview screen area is moved vertically. Divide into two. The specific headword “Wakaba [Wakaba]” and the explanation corresponding to the Japanese dictionary mode are displayed in the upper half area of the divided preview screen area, and the specific headword “Wakaba [Wakaba]” is displayed in the lower half area. And a commentary corresponding to the Japanese-English dictionary mode may be displayed.
As described above, according to the second modified example, by dividing the preview screen area, explanations of a plurality of specific headwords can be displayed on one screen in the display 30. Can be improved.

(Third Modification)
In the portable electronic dictionary 1 described in the present embodiment, the area of the display area of the display 30 constituting the display unit 13 is considerably limited as compared with the display provided in the desktop PC.
Therefore, in the third modified example, a display method for changing the character size according to the amount of information to be displayed in order to further improve the listability in the electronic dictionary 1 will be described.
For example, as described in the second modification, when the preview screen area is divided and a plurality of specific headword explanations are displayed as a list, the area of an area allocated to display a single headword explanation Is further limited according to the number of divisions of the preview screen area.
That is, the explanation of each headword must be displayed in a small area extremely limited in the preview screen area.
Therefore, if the amount of explanation information corresponding to the headword is large, it is possible that not all the explanation information can be displayed in the assigned display area with the display character size in the default setting (default setting). There is. If all information is not displayed, the user needs to perform a predetermined screen scrolling operation or page turning operation in order to confirm the contents of all the explanations.

Therefore, in order to reduce the burden on the user due to such an operation, the display character size in the preview screen area is automatically set based on the amount of commentary information corresponding to the headword and the size (size) of the allocated display area. You may make it change automatically.
Such an automatic change process of the display character size can be executed by starting the display setting change program 168.
Specifically, the CPU 11 compares the amount of commentary corresponding to the headword and the size of the assigned display area, and can display all of the commentary corresponding to the headword and the headword in the assigned display area. The correct character size. Then, after changing the display character size setting based on the calculated character size, information display processing in the preview screen area is performed.

However, in the electronic dictionary 1, in order to execute display processing within a visible range, a minimum display character size, that is, a lower limit value of the character size to be displayed is set in advance. Therefore, when the character size calculated in the above-described processing is smaller than the minimum display character size, the display processing is executed by changing the display character size setting to the minimum display character size.
The display character size automatic change function can be enabled / disabled by operating a predetermined function key 22 to which the display size automatic change function is assigned.
As described above, according to the third modification, by changing the character size in accordance with the amount of information to be displayed, more information can be displayed on one screen of the display 30, so that the list in the electronic dictionary 1 can be displayed. The sex can be further improved.

(Fourth modification)
In the third modified example described above, the display method for automatically changing the display character size to a small size has been described. However, the display method for improving the listability in the electronic dictionary 1 is not limited to this.
Therefore, in the fourth modification, a display method for changing the ratio between the main screen area and the preview screen area will be described as another display method for further improving the listability in the electronic dictionary 1.
In the embodiment described above, the ratio between the main screen area and the preview screen area is always fixed. For this reason, the size of the main screen area is fixed based on the ratio stored in the initial setting data 162 regardless of the amount of commentary information corresponding to the specified headword.

Therefore, for example, when the amount of commentary information corresponding to the specified headword is very small, the lower area in the main screen area is a wide blank area (empty area) in which no information is displayed.
Therefore, in order to use the display screen area on the display 30 more effectively, the main screen area, the preview screen area, and the like can be used as the preview screen area. The ratio may be automatically changed.
Such a display area ratio change can be executed by starting the display setting change program 168 in the same manner as the display character size automatic change process described above.

Specifically, the CPU 11 calculates comment information corresponding to the designated headword, that is, an area size in which the headword and all the comment information can be displayed in the main screen area. Then, after changing the display ratio between the main screen area and the preview screen area based on the calculated character size, information display processing in the preview screen area is performed.
However, if the area size calculated in the above processing exceeds the size of the main screen area based on the display ratio in the initial setting (default setting), the display character size setting is set to the display ratio defined by the initial setting. Based on this, display processing is executed.
The display area automatic change function can be enabled / disabled by operating a predetermined function key 22 to which the display area automatic change function is assigned.

Thus, according to the fourth modification, the size of the main screen area, that is, the display ratio between the main screen area and the preview screen area is changed according to the amount of commentary information corresponding to the specified headword. Thus, the display screen area on the display 30 can be used more effectively.
In particular, when the amount of information of specific headwords to be displayed in the preview screen area is large, more information can be displayed on one screen in the display 30, so that the listability in the electronic dictionary 1 is further improved. Can do.
Further, by using the automatic change function of the display area described in the fourth modification and the automatic change function of the display character size described in the third modification, more information can be displayed on one screen of the display 30. Since it can be displayed, the list property in the electronic dictionary 1 can be further improved.
