  Next, the operation of the electronic dictionary device with a handwriting input function 10 having the above configuration will be described.

  FIG. 3 is a flowchart showing a handwritten dictionary search process for searching a dictionary from characters handwritten by the electronic dictionary device 10 with a handwriting input function.

  This handwritten dictionary search process is broadly divided into a dictionary selection process (step SA), a search character string input process (step SB), and a specified headword explanation information display process (step SC).

  In the dictionary selection process (step SA), the input method for handwriting input of the search character string is switched according to the language (Japanese, English, etc.) of the dictionary entry word selected according to the user operation. Set.

  In the search character string input process (step SB), the search character string input by handwriting is recognized / corrected / confirmed according to the input method switched and set in the dictionary selection process. Then, a headword search is performed according to the determined search character string and a list is displayed.

  In the description information display process (step SC) of the designated headword, the translated word / semantic content corresponding to the headword designated in accordance with the user operation from the headwords displayed as a list in the search character string input process Read various explanatory information such as example sentences (examples) from the dictionary data 24a, 24b,. Then, the designated headword and its explanation information are displayed on the touch panel display unit 17 in full screen.

  FIG. 4 is a flowchart showing dictionary selection processing accompanying handwriting dictionary search processing of the electronic dictionary device 10 with handwriting input function.

  FIG. 5 is a diagram illustrating a display operation corresponding to a user operation accompanying a dictionary selection process of the electronic dictionary device 10 having the handwriting input function.

  When the “menu” key of the key input unit (keyboard) 14 is input in response to a user operation (step A1 (Yes)), one of the dictionary data 24a, 24b,... Is selected as a search target dictionary. A dictionary selection screen is displayed on the touch panel display unit (main screen) 17 (step A2).

  When the display item of the dictionary desired by the user is selectively touched and input on the dictionary selection screen displayed on the touch panel display unit (main screen) 17, the selected dictionary is selected (step A3 (Yes)). A search character string input screen G (see FIG. 5) corresponding to the data is displayed on the touch panel display unit (main screen) 17 (step A4).

  Here, the search character string input screen G includes a search character input area Mk in which characters input in response to a user operation are displayed, and search characters (strings) input and displayed in the search character input area Mk. A headword list area Lm in which headwords matching the head are searched and displayed as a list, and explanation information corresponding to the headword specified by the reverse cursor Ch in this headword list area Lm is read and previewed. It consists of a description information preview area Vp.

  Then, when it is determined that the dictionary data selected by the user is English dictionary data (English-Japanese dictionary) 24b whose headword characters are alphabets, as shown in FIG. 5A, for example ( Step A6 (Yes)), the handwritten input unit (sub-screen) 16 displays a 5 枡 English handwritten character input frame 16e1 to 16e5 obtained by dividing the horizontal direction into five, and the handwritten character input frame 16e1 An English recognized character display area 16en in which recognized characters are sequentially input and displayed, and a “rewrite” button 16r instructing the rewriting of the immediately preceding character are displayed immediately above 16e5 (step A7).

  In the handwriting input unit 16, a “recognition” button 16b1, a “decision” button 16b2, a “return” button 16b3, and a “headline memo” button 16b4 are always displayed during operation along the upper end.

  Also, the dictionary data selected by the user is determined to be Japanese (Kanji) -based dictionary data (Japanese dictionary) 24a in which the characters of the headword are kanji or hiragana as shown in FIG. 5B, for example. (Step A5 (Yes)), the handwritten character input frames 16k1 and 16k2 are displayed on the right side of the handwriting input unit (subscreen) 16 divided into three in the horizontal direction, On the left hand side, a recognized character display area 16kn for the national language in which recognized characters are sequentially input and displayed, and a “rewrite” button 16r for instructing rewriting of the immediately preceding character are displayed (step A8).

  That is, in the case of an English dictionary, since all the search character strings are input by simple stroke alphabets, the input handwriting character input frames 16e1 to 16e5 for English are surely small even if the input frame area per character is small. More handwritten characters can be input, and as the number of input frames increases, a series of handwritten characters (such as word spelling) can be efficiently input as a search character string.

  In the case of a national language (kanji) dictionary, the search character string is input with kanji and hiragana in a complicated stroke, so that the number of the handwritten character input frames for national language 16k1 and 16k2 is at least one. Since the input frame area per character is large, handwritten characters can be input accurately, and search character strings such as idioms including kanji can be input efficiently.

  Further, the dictionary data selected by the user is not the national language (Kanji) dictionary data (Japanese dictionary) 24a or the English (alphabet) dictionary data (English-Japanese dictionary) 24b, but other language dictionary data. If it is determined that there is (Step A6 (No)), an operation menu corresponding to the dictionary is displayed, or the number and size of frames suitable for handwriting input of a search character string in another language. The handwritten character input frame is displayed on the handwriting input unit (sub-screen) 16 (step A9).

  FIG. 6 is a flowchart showing a search character string input process accompanying the handwritten dictionary search process of the electronic dictionary device 10 with a handwriting input function.

  FIG. 7 is a flowchart showing the description information display process of the specified headword accompanying the handwritten dictionary search process of the electronic dictionary device 10 with a handwriting input function.

  For example, as shown in FIG. 5 (A), when the English dictionary data (English-Japanese dictionary) 24b is selected, five handwritten English character input frames 16e1 to 16e5 are displayed on the handwriting input unit 16. In the state, when handwritten characters “h”, “o”, “b”, “b”, and “y” are input to the character input frames 16e1 to 16e5 (step B1), handwritten characters are sequentially input to the next input frame. Each time, the handwritten character input in the input frame immediately before it is recognized, and the character-recognized conversion candidate character is stored in the character recognition conversion candidate buffer 27 in the memory 23 (step B2).

  Then, the first recognized character recognized as the character is used for English in the search character input area Mk of the search character string input screen G in the touch panel display unit (main screen) 17 and the handwriting input unit (sub screen) 16. In addition to the recognized character display area 16en, it is sequentially input and displayed (step B3).

  Then, the headwords “Hobbes”, “hobbles”... Matching the search character strings “hobb...” Sequentially input and displayed in the search character input area Mk of the touch panel display unit (main screen) 17 are dictionary data (English-Japanese). The dictionary is searched from 24b (step B4), and is displayed as a list in the entry word list area Lm of the touch panel display unit (main screen) 17 (step B5).

  At this time, among the headwords displayed in a list in the headword list area Lm of the touch panel display unit (main screen) 17, the headword “Hobes” is designated by default with the reverse cursor Ch, and the designation The explanation information corresponding to the headword “Hobbes” is read from the dictionary data (English-Japanese dictionary) 24b and previewed in the explanation information preview area Vp of the touch panel display unit (main screen) 17.

  Further, for example, as shown in FIG. 5B, the two-language handwritten character input frames 16k1 and 16k2 are displayed on the handwriting input unit 16 when the Japanese-language dictionary data (Japanese dictionary) 24a is selected. When the handwritten characters “raw” and “industry” are input to the character input frames 16k1 and 16k2 in the state of being input (step B1), the input frame immediately before the handwritten character is sequentially input to the next input frame. The handwritten character input to the character is recognized, and the character-recognized conversion candidate character is stored in the character recognition conversion candidate buffer 27 in the memory 23 (step B2).

  Then, the first recognized character recognized as the character is used for the national language of the search character input area Mk of the search character string input screen G and the handwriting input portion (sub-screen) 16 in the touch panel display portion (main screen) 17. In addition to the recognized character display area 16kn, it is sequentially input and displayed (step B3).

  Then, the headwords “go [raw]” “ubu [productive / raw] that first match the search character string“ raw ... ”that is sequentially input and displayed in the search character input area Mk of the touch panel type display unit (main screen) 17. "First" "... is retrieved from the dictionary data (Japanese dictionary) 24a (step B4), and is displayed in a list in the headword list area Lm of the touch panel display unit (main screen) 17 (step B5).

  At this time, among the headwords listed in the headword list area Lm of the touch panel type display unit (main screen) 17, the headword “go [raw]” is designated by default with the reverse cursor Ch, The explanation information corresponding to the designated entry word “go [raw]” is read from the dictionary data (Japanese dictionary) 24a and previewed in the explanation information preview area Vp of the touch panel display unit (main screen) 17. The

  In addition, the character recognition process (step B2) about the last handwritten character "y" ("work") input into the handwritten character input frames 16e1 to 16e5 (16k1, 16k2) of the handwriting input unit 16 is the last This is executed by touch-inputting the “recognition” button 16b1 of the handwriting input unit 16 with the input of the handwritten character (step B1).

  Here, along with the input of handwritten characters to the handwritten character input frames 16e1 to 16e5 (16k1, 16k2) and the character recognition of the handwritten input unit 16, the search character input area Mk of the touch panel display unit (main screen) 17 and The correction process of the search character input and displayed on both the recognized character display area 16en (16kn) of the handwriting input unit (sub-screen) 16 will be described.

  FIG. 8 is a diagram illustrating a display operation corresponding to a user operation associated with a search character string input / correction process and a description information display process of a specified headword in the electronic dictionary device 10 having the handwriting input function.

  For example, as shown in FIG. 8A, in response to the selection of the Japanese-language dictionary data (national language dictionary) 24a, the two-language handwritten character input frames 16k1 and 16k2 displayed on the handwriting input unit 16 are selected. Then, a desired search character string “Seiyo” is input by handwriting to be recognized (steps B1 to B8 (No) → B10 (No) → B1, B2).

  Here, as shown in FIG. 8 (B), the candidate character “leaf” that is erroneously recognized for the handwritten character “yo” at the end of the desired search character string “living business” is displayed on the touch panel display unit ( When the character is additionally input and displayed in both the search character input area Mk of the main screen) 17 and the recognized character display area 16kn of the handwriting input unit (sub-screen) 16 (steps B3 to B5), the user The erroneous candidate character “leaf” is touched and specified in either the input area (main screen) Mk or the recognized character display area (subscreen) 16kn (step B6 → B7 (Yes) or B8 (Yes)). .

  Then, as shown in FIG. 8C, the characters in the memory 23 together with the candidate character “leaf” touched and specified in the search character input area (main screen) Mk or the recognized character display area (subscreen) 16 kn. Each conversion candidate character stored in the recognition conversion candidate buffer 27 is read and displayed in a list in the conversion candidate character list area 16L replaced with the character input frames 16k1 and 16k2 of the handwriting input unit 16. Then, when the correct candidate character “K” is selected and touched from among the conversion candidate characters displayed as a list in the conversion candidate character list area 16L, as shown in FIG. The candidate character “industry” is replaced with the erroneous candidate character “leaf”, and the search character input area Mk of the touch panel display unit (main screen) 17 and the recognized character display area of the handwriting input unit (subscreen) 16 16en (16kn) is input and displayed and corrected (step B9).

  Then, the headwords “Sugai [Saiyo]”, “Saiwaii [Saiyo]” that match the search character string “Saiyo” entered and displayed in the search character input area Mk of the touch panel display unit (main screen) 17... Is retrieved from the dictionary data (Japanese dictionary) 24a (step B4) and displayed in a list in the entry word list area Lm of the touch panel display unit (main screen) 17 (step B5).

  Here, among the headwords displayed in a list in the headword list area Lm, the headword “Sugai [Living]” desired by the user is specified by pen-touching, and is identified and displayed by the reverse cursor Ch. When the “translation / decision” key 14c is input (step B6 (Yes)), the process proceeds to the explanation information display process in FIG.

  Then, the explanation information corresponding to the designated headword “Sugiai [Living]” is read from the dictionary data (Japanese dictionary) 24a (step C1), and as shown in FIG. Is displayed as an explanation information display screen G1 on the entire screen of the section (main screen) 17 (step C2).

  In the explanation information display screen G1 displayed on the entire screen of the touch panel display unit (main screen) 17 as described above, when an upper part in a certain area is touched and specified from the upper part of the screen (Step C3 (Yes)). ), The explanation information currently being displayed is scrolled up and displayed, and the contents following the explanation information can be viewed (step C4).

  On the other hand, when the lower part of the certain area is touched and specified from the lower part of the explanation information display screen G1 (step C5 (Yes)), the explanation information currently displayed is scrolled down and displayed. The contents that follow the explanatory information can be viewed (step C6).

  Next, in the dictionary selection process (step SA) in FIGS. 3 and 4, a search character string using handwritten characters when kanji dictionary data (kanji dictionary) 24c for searching for unknown kanji is selected. The input function (steps A1 to A6 (No) → A9) will be described in detail.

  FIG. 9 is a flowchart showing a search process in a Chinese character dictionary associated with a handwritten dictionary search process of the electronic dictionary device 10 with a handwriting input function.

  FIG. 10 is a diagram showing a display operation corresponding to a user operation accompanying a search process in the Chinese character dictionary of the electronic dictionary device 10 having the handwriting input function.

  When the kanji dictionary data (kanji dictionary) 24c is selected on the dictionary selection screen displayed on the touch panel display unit (main screen) 17 in response to the user operation of the “menu” key, the kanji dictionary in FIG. The search process in is started. Then, as shown in FIG. 10A, a search method selection screen G2 which is an initial screen of the kanji dictionary (24c) is displayed on the touch panel display unit 17 (step A9a).

  In the search method selection screen G2, when the item “[A] Search for single kanji / jukugo word from handwritten input” is selected and touch-inputted, and is displayed with the reverse cursor Ch (steps A9b, A9c (No)). As in the case of selecting the Japanese dictionary (24a) shown in FIG. 5B, the horizontal direction is divided into three in the handwriting input unit (sub-screen) 16 as shown in FIG. 10B. Kanji handwritten character input frames 16k1 'and 16k2' are displayed on the right side 2 and the recognized character display area 16kn 'for kanji in which recognized characters are sequentially input and displayed in the left side 1c. , And the “rewrite” button 16r for instructing the rewriting of the immediately preceding character is displayed (step A9d).

  That is, when searching for a single kanji or idiom in a kanji dictionary, even if the number of the kanji handwritten character input frames 16k1 'and 16k2' is small, the frame area per character is large, so Handwritten characters can be input, and search characters for kanji and idioms can be input efficiently.

  Then, when a desired Chinese character is input by handwriting in accordance with the handwritten character input frames 16k1 'and 16k2' for the Chinese character of the handwriting input unit 16, the handwritten character is recognized and the search character input area Mk of the touch panel display unit 17 and the handwritten character It is input and displayed both on the kanji recognition character display area 16kn 'of the input unit (sub-screen) 16. Then, a headword that first matches the search character string input and displayed in the search character input area Mk is searched from the kanji dictionary data (kanji dictionary) 24c, for example, as shown in FIG. 5B. A list is displayed in the headword list area Lm (step A9f).

  On the other hand, in the search method selection screen G2 shown in FIG. 10A (step A9a), the item “[B] Search single kanji from large handwritten input” is selected and touch-inputted, and the reverse cursor Ch is used. When the identification display is made (steps A9b, A9c (Yes)), as shown in FIG. 10C, the touch panel type display unit (main screen) 17 occupies most of the right half of the display screen. A single Kanji input screen G3 having a Kanji handwriting input frame 17k is displayed. In the upper part of the single-kanji handwriting input frame 17k of the single-kanji input screen G3, a “recognition” button 17b1 for instructing recognition of a handwritten character input in the handwriting input frame 17k and an instruction for rewriting the handwritten character “ A “rewrite” button 17r is displayed (step A9e).

  That is, for example, when searching for a complex single kanji with many strokes in the kanji dictionary, the input frame area of the handwritten input frame 17k for single kanji displayed on the single kanji input screen G3 of the touch panel type display unit 17 is displayed. By being very large, it is possible to accurately input handwritten Chinese characters, and to efficiently input single kanji search characters.

  Then, when a desired single kanji is input by hand according to the single-kanji handwriting input frame 17k of the touch panel display unit 17 and the “recognition” button 17b1 is touch-input, the handwritten kanji is recognized. Then, the first character recognized as the character is switched to the single kanji input screen G3 of the touch panel type display unit 17 to be displayed and the recognized character for kanji in the handwriting input unit (sub-screen) 16 is displayed. It is input and displayed in both the display area 16kn '. A headword that first matches the search character (single kanji) entered and displayed in the search character input area Mk is searched from the kanji dictionary data (kanji dictionary) 24c and displayed in a list in the headword list area Lm. (Step A9f).

  It is to be noted that a desired headword is selectively designated from the headwords displayed in a list in the headword list area Lm of the touch panel display unit 17, and explanation information including the designated headword and its explanation information. The process for displaying the display screen G1 (explanatory information display process) is executed in the same manner as the explanatory information display process (steps C1 to C6) shown in FIG.

  Therefore, according to the electronic dictionary device 10 with the handwriting input function configured as described above, a dictionary desired by the user to be used as a search target is touched and selected on the dictionary selection screen displayed on the touch panel display unit (main screen) 17. . When the selected dictionary is English dictionary data 24b, the handwritten input unit 16 displays five English handwritten character input frames 16e1 to 16e5 obtained by dividing the input region into five in the horizontal direction. If the dictionary data 24a is Japanese-language dictionary 24a, two handwritten character input frames 16k1 and 16k2 for the two languages out of the input region divided into three in the horizontal direction are displayed on the handwriting input unit 16. Is done. If the dictionary is an English dictionary (24b), a spelling character such as a word to be searched for is input as a handwritten character using the 5 枡 English handwritten character input frames 16e1 to 16e5, and the character is recognized as a search character. Perform a headword search as a column. In the case of a Japanese dictionary (24a), a kanji word to be searched using the 2nd handwritten character input boxes 16k1 and 16k2 for Japanese characters is input as handwritten characters, and the character recognition is used for the search. Search for headwords as a character string.

  For this reason, in the case of an English dictionary in which all search character strings are input using simple stroke alphabets, the input frame area per character is small in the 5 枡 English handwritten character input frames 16e1 to 16e5. In addition, a correct handwritten character can be input, and as the number of input frames increases, a series of handwritten characters (word spelling, etc.) can be efficiently input as a search character string. Further, in the case of a national language (kanji) dictionary in which a search character string is input using complex strokes of kanji or hiragana, even if the number of frames is small in the above-mentioned 2 枡 national language handwritten character input frames 16k1 and 16k2. Since the input frame area per character is large, handwritten characters can be input accurately, and search character strings such as idioms including kanji can be input efficiently.

  Moreover, according to the electronic dictionary device 10 with the handwriting input function having the above-described configuration, handwritten characters are input in the handwritten character input frames 16e1 to 16e5 for English and the handwritten character input frames 16k1 and 16k2 for Japanese displayed on the handwriting input unit 16. In the case of input, the first candidate character that has been recognized is input and displayed in both the recognized character display area 16en (16kn) in the handwriting input unit 16 and the search character input area Mk in the touch panel display unit 17. A headword search that matches the character string input and displayed in the search character input area Mk is performed. At this time, either the candidate character input and displayed in the search character input area Mk of the touch panel display unit 17 or the candidate character input and displayed in the recognized character display area 16en (16kn) of the handwriting input unit 16 is selected. Even if it is specified by touching, it becomes a mode for correcting the specified candidate character, and conversion candidate characters corresponding to the candidate character are displayed in a list on the handwriting input unit 16 and can be corrected.
