First, when the user selects a use dictionary using the keyboard 12a or the like (step S1), the control unit 11 reads out dictionary search data of the selected dictionary (step S2). Next, the character that the user wants to search is input from the keyboard 12a (step S3). When the control unit 11 receives a character input signal indicating that a character has been input, the control unit 11 searches the dictionary data and displays a headword list on the display unit 13 (step S4). On the other hand, the user selects a desired entry word from the entry word list using the keyboard 12a (step S5). By default, the heading word at the top position is selected.

  Next, the control unit 11 displays a translation screen of the selected headword on the display unit 13 (step S6), whether there is phrase data in the corresponding headword (step S7), and whether there is example sentence data. (Step S9) is determined. If there is phrase data, the phrase list is displayed in another window (step S8), and if there is example sentence data, the example sentence list is displayed in another window (step S10). If there is no corresponding phrase data, or if there is no corresponding example sentence data, display nothing but display the phrase list and another empty window corresponding to the example sentence list. Also good.

  As a result, as shown in the screen 100 of FIG. 6, the phrase list is displayed in the separate window 32 on the preview screen including the keyword list 30 and the translation 31 of the selected keyword as a phrase / example sentence list display. An example sentence list is displayed at 33. The number of hit phrases 321 is displayed in the title bar of another phrase list window 32, and the number of hit sentences 331 is displayed in the title bar of another phrase list window 33.

  Next, the control unit 11 determines whether or not the switch key 23 has been operated (step S11). When the switch key 23 is operated, the control unit 11 is shown in FIG. 6 each time the switch key 23 is operated. Thus, the phrase / example sentence list display shown on the screen 100 is switched to the phrase list display shown on the screen 200, the phrase list display is changed to the example sentence list display shown on the screen 300, and the normal sentence display shown on the screen 400 is switched from the example sentence list display. (Step S12). Although not shown in the figure, in each screen display, as shown in steps S7, S8, S9, and S10 described above, the presence / absence of phrase data and the presence / absence of example sentence data may be determined. The determination results in S8, S9, and S10 may be held and used.

  As shown in FIG. 6, in the phrase list display shown on the screen 200, only the phrase list is displayed in the separate window 32 on the preview screen including the headword list 30 and the translation 31 of the selected headword. The number of hit phrases 321 is displayed on the title bar of another phrase list window 32. In the example sentence list display shown on the screen 300, only the example sentence list is displayed in the separate window 33 on the preview screen including the entry word list 30 and the translation 31 of the selected entry word. The number 331 of hit example sentences is displayed in the title bar of another window 33 of the example sentence list. In the normal display shown on the screen 400, only the preview screen including the headword list 30 and the translation 31 of the selected headword is displayed.

  Next, in each screen, it is determined whether or not the enter key 26 has been operated (step S13). If the enter key 26 has not been operated, the process returns to step S11 to perform the display switching operation described above. In each screen, an entry word can be selected, a list can be scrolled, and the like by an operation using the cursor key 24. Further, by selecting a headword in the headword list 30 by moving the cursor key 24 up and down, the translation 31 of the headword, the phrase list, and the example sentence list are switched in real time.

  Further, the screen 100 to the screen 400 are sequentially switched by the switching key 23, and after the determination key 26 is pressed on any screen, a predetermined active window switching key (one key has a role of an active window switching key). Or a dedicated key for the active window switching key may be provided). For example, if the screen 100 is used, the headword translation 31, the phrase list 32, and the example sentence list 33 are activated. Switch windows sequentially. For example, when the up / down cursor key 24 is pressed in the switched window, the display of the headword translation, phrase list, and example sentence list is scrolled.

  On the other hand, when the enter key 26 is operated on any screen, the translation of the headword selected at that time is displayed (step S14). By default, the phrase / example sentence list that displays the corresponding phrase list and example sentence list in a separate window on the entry word translation display screen, regardless of which screen is displayed when the enter key 26 is operated. Display. In addition to this, the screen corresponding to the screen at the time when the enter key 26 is operated, that is, the phrase / example list display for the phrase / example list display, the phrase list display for the phrase list display, and the example list display for the example list display In addition, normal display may be switched to normal display.
