  FIG. 6 is a diagram showing an operation display state (first example) associated with a jump search from a Korean character text in a dictionary search process by the portable device (electronic dictionary) 10.

  For example, when performing a Korean dictionary search, if the “Japanese-Korean” key of the input unit 16 is operated to select the Korean dictionary data [Japan-Korea] 12b (step S1), this Korean dictionary (12b) A search word input screen (not shown) based on the above is displayed on the display unit 17 (step S2).

  On this search word input screen, for example, when “Soul” is input as a search word in Japanese (step S3), this search word “Soul” is stored in the search character data memory 12e and the search word The text data of the translation (explanatory information) of Korean characters corresponding to “Seoul” in Korean is read from the Korean dictionary data [Japan-Korea] 12b and explained as shown in FIG. 6 (A2). The information display screen G2 is displayed on the display unit 17 (step S4).

  On the other hand, for example, when the Korean text document data stored in the document data memory 12d is designated (step S5), the designated Korean text is read out, as shown in FIG. 6 (A1). The text display screen G1 is displayed on the display unit 17 (step S6).

  As described above, in the text display screen G1 of the Korean text shown in FIG. 6 (A1) or the explanation information display screen G2 by the Korean dictionary [Japan-Korea] shown in FIG. In order to perform a jump search from the text in the column, after the “jump” key is operated to switch to the jump search mode (step S7), the reverse cursor K on the text is controlled to move according to the operation of the cursor key. When the first character of an arbitrary character string to be jump searched is designated and the “translation / decision” key is operated, a series up to a subsequent delimiter (for example, a period) including the designated one character is operated. Is selected (see FIGS. 6A1 and 6A2) (step S8).

  Then, it is determined whether the selected character string for jump search is a Hangul character or a language character other than that (step S9), and it is determined that it is a language character such as an alphabet or a Chinese character that is not a Hangul character. If so (step S9 (NO)), a normal jump search process based on the dictionary data (12c) of the alphabetic dictionary or the kanji dictionary is executed, and the longest matching word with the selected character string is executed. Are searched and displayed in a list (step S10).

  On the other hand, as shown in FIGS. 6A1 and 6A2, if it is determined that the selected character string for jump search is a Hangul character (in this case, a Hangul character of “Soul”) (step S1). S9 (YES)), first, Korean headwords that match the selected Korean character string are sequentially searched based on the Korean dictionary data “Korean” and “Korean” (12b). It is stored while being added to the headword list memory 12g (step S11).

  Then, as shown in FIG. 4, the character string of the selected Hangul character (“Seoul” Hangul character) is used to form each character constituting the character from the completed character code for each character. Each character is converted into a combination type code and divided into characters (step S12), and according to the Hangul / alphabet code conversion table 12f (see FIG. 2), an alphabetic character string (in this case, “SEOUL”) for each divided character. (Step S13).

  Then, according to the alphabet character string “SEOUL” corresponding to the Korean character string (“Seoul” Korean character) of the jump search target converted in this way, each alphabetic dictionary (“English-Japanese” “English-English” “ On the basis of the dictionary data (12c), etc.), each headword of the alphabet language that matches the converted alphabet character string is sequentially searched and added to the search headword list memory 12g. Stored (step S14).

  Then, while the last character of the selected Korean character string to be searched for jump is deleted one character at a time (step S15), the same code conversion / character division processing is performed on the Korean character string after each character deletion. This is executed (step S16 → S12) and converted to alphabet (step S13), and the headword of the alphabet language that matches the corresponding alphabet character string after the deletion of one Hangul end character is stored in each of the alphabet-based dictionary data ( 12c) are sequentially searched and further added to the search word list memory 12g and stored (step S14).

  Then, the character division / alphabet conversion / entry word search process is repeated every time after the last character of the selected Korean character string is deleted, and it is determined that there is no longer a Korean character string to be searched (steps S15 and S16). YES)), Korean headwords searched based on the Korean dictionary data “Korean” and “Korean” (12b) stored in the search headword list memory 12g, and the alphabet The search terms list screen G3 as shown in FIG. 6B shows the search terms of the alphabetic language searched based on each dictionary data (such as “English-Japanese”, “English-English”, “German-Japanese”) (12c). Is displayed on the display unit 17 (step S17).

  At this time, with respect to the headword identified and displayed by the reverse cursor K whose movement is controlled in accordance with the user operation of the cursor key on the search headword list screen G3, the search source dictionary data (12b) of the headword , 12c), the corresponding explanation information is read out and displayed as a preview screen P in a window.

  Then, when the "translation / decision" key is operated in a state where the desired headword is identified and displayed by moving and displaying the reverse cursor K by the cursor operation on the search headword list screen G3 ( In step S18 (YES), the explanation information of the translation corresponding to the selected entry word is read from the search source dictionary data (12b, 12c) of the entry word, for example, FIG. As shown in C3), an explanation information display screen G2 corresponding to each of the selected headwords is displayed on the display unit 17 (step S19).

  Here, FIG. 6 (C1) corresponds to the alphabet character string “SEOUL” converted from the Hangul character string (in this case, the “Hangul character of“ Seoul ”) selected as the jump search target to the alphabet conversion by code conversion / character division. The explanatory information display screen G2 retrieved and read from the English-English dictionary (12c) is shown, and FIG. 6 (C2) corresponds to the alphabet character string “SEOUL” converted to the same alphabet. The explanatory information display screen G2 retrieved and retrieved from the Japanese dictionary (12c) is shown, and FIG. 6 (C3) corresponds to the alphabet character string “SEOUL” converted to the same alphabet, and the reverse lookup word (12c). The explanation information display screen G2 retrieved and read from () is shown.

  FIG. 7 is a diagram showing an operation display state (second example) associated with a jump search from a Korean character text in a dictionary search process by the portable device (electronic dictionary) 10.

  For example, the Korean text display screen G1 (step S5 → S6) shown in FIG. 6 (A1), or the explanatory information display screen G2 (Korean dictionary [Japan-Korea] shown in FIG. 6 (A2). In steps S1 to S4), in order to perform a jump search from the text of the Korean character string, after the “jump” key is operated to switch to the jump search mode (step S7), the cursor key is operated in accordance with the operation. When the first character of an arbitrary character string (in this case, “Hangul character of“ Kimchi ”) as a jump search target is designated and the“ translation / decision ”key is operated, the reverse cursor K on the text is controlled to move. A series of character strings including the designated one character and the subsequent delimiters (for example, a period) are selected (step S8).

  Then, it is determined that the selected character string for jump search is a Hangul character (in this case, two Korean characters “Kimchi”) (step S9 (YES)). Based on “Korean / English” (12b), Korean headwords that match the two Korean characters of the selected “Kimchi” reading are sequentially searched and stored in the search headword list memory 12g (step). S11).

  Then, as shown in FIG. 4, the character string of the two selected Korean characters (“Kimchi” Korean characters) is composed of each character constituting each character from the completed character code for each character. It is converted into a combination type code for each character and divided into characters (step S12), and in accordance with the Hangul / alphabet code conversion table 12f (see FIG. 2), an alphabetic character string (in this case, “kimchi”) for each divided character. (Step S13).

  Then, according to the alphabet character string “kimchi” corresponding to the Korean character string (“Kimchi” Korean character) of the jump search target converted in this way, each alphabetic dictionary (“English-Japanese”, “English-English”, etc.) ) Dictionary data (12c), the headwords “kim, chi, kim, chee”... Of the alphabetic language that match the converted alphabet string are sequentially searched, and the search headword list memory is searched. It is stored while being added to 12g (step S14).

  Then, the last two characters of the selected “Kimchi” Hangul character that is the jump search target are deleted (step S15), and the same code is used for the “Kim” Korean character after each character deletion. The conversion / character split processing is executed (step S16 → S12), converted to the alphabet “kim” (step S13), and the alphabetic word “kim”... Matching the alphabet character string “kim” is converted into the alphabet. The search is sequentially performed based on the dictionary data (12c) of the system, and is further stored in the search word list memory 12g (step S14).

  Then, the Korean headword (“Kimchi” in Korean) searched based on the Korean dictionary data “Korean” and “Korean” (12b) stored in the search headword list memory 12g. Headwords), and headwords “kim chi”, “kim chee”, “kim” of alphabetic languages searched based on the alphabet dictionary data (“English-Japanese”, “English-English”, etc.) (12c) Are displayed on the display unit 17 as a search word list screen G3 as shown in FIG. 7A (step S17).

  At this time, on the search headword list screen G3, the headword (two Korean characters of “Kimchi” by the Korean-Japanese dictionary) identified and displayed by the reverse cursor K that is moved and controlled in accordance with the user operation of the cursor key. The corresponding explanation information “Kimchi” is read from the “Korean-Japanese” dictionary data (12b), which is the search source of the headword, and displayed as a preview screen P in a window.

  In the search headword list screen G3, the reverse cursor K is moved and displayed by a cursor operation to identify and select the desired headword “kim · chi, kim · chee”, When the “OK” key is operated (step S18 (YES)), the explanation information “Kimchi (pickled Chinese cabbage and other pickles such as Korean spicy Chinese cabbage) corresponding to the selected and determined headword“ kim / chi, kim / chee ”” ) [Korean] ”is read out from the“ English-Japanese ”dictionary data (12c) that is the search source of the headword, and as shown in FIG. 7B, the selected headword“ kim · chi, kim · The explanation information display screen G2 corresponding to “chee” is displayed on the display unit 17 (step S19).
