Description

  The present invention relates to a character input device and a character input method for inputting idioms, and more particularly to an embodiment that is suitably implemented in an electronic dictionary device equipped with a Chinese dictionary.

  When inputting Chinese to be searched, particularly idioms, to an electronic dictionary device equipped with a Chinese dictionary, conventionally, input by Pinyin, input of the first character, etc. are performed. In the case of the input by pinyin, the input is based on the pronunciation, and the user can input the idiom by inputting the pronunciation of the idiom to be searched for in the syllable represented by the alphabet. In the case of inputting the first kanji, when the user inputs the first kanji of the idiom that the user wants to search, the idiom candidate including the input kanji as the first character is displayed, so that the user is displayed. An idiom can be input by selecting a desired idiom from the candidates.

  The kanji selection device described in Patent Document 1 is considered as one of means for inputting the first kanji, for example. When a reading is input in kana-kanji conversion, this kanji selection device displays the first five characters of conversion candidates and the number of selection candidates. Furthermore, the number of selection candidates can be narrowed down by performing an additional search such as a radical search.

  In Chinese, when inputting Pinyin, it is possible to input Chinese idioms to be input directly, but there is a problem that a user who does not know the reading cannot input. In addition, when inputting the first kanji, the input kanji and all the idioms with the kanji as the first character are displayed as candidates, so if there are very many candidates, it takes time to display the candidates. There is a problem that the operation when the user makes a selection becomes complicated. Furthermore, even in Japanese, if you do not know how to read idioms, you can input idioms if you can input the reading of each kanji character, but there is no such character input device. The kanji selection device described in Patent Document 1 is suitable as a means for inputting the first kanji, but does not describe or suggest the input of idioms.

  An object of the present invention is to provide a character input device and a character input method that are easy to use for many users and can input idioms of kanji with a simple operation.

  In the electronic dictionary device 1, the user can input two or more kanji characters and perform a phrase search using the input kanji as a search key. Here, a procedure for inputting and searching for the idiom “Anne” will be described. Note that “Anhui”, which is an example of an idiom to be input, is written in Japanese kanji in this specification, but actually, as shown in the display screen examples in FIGS. Chinese kanji (simplified) can be entered.

  FIG. 4 is a diagram showing an example of a display screen when inputting Chinese characters. Hereinafter, a character input procedure for inputting the first character will be described with reference to FIG.

  When the user presses the power key 14 while the electronic dictionary device 1 is turned off, the power is turned on, and an initial screen such as a main menu screen is displayed on the display unit 11. When the user selects a Chunichi dictionary from the main menu or presses the Chunichi key, a Chunichi dictionary initial screen 30 shown in FIG. 4A is displayed on the display unit 11. The Chunichi Dictionary initial screen 30 has a direct input area 30a including a Pinyin input area and a Japanese reading input area. When character input is performed by pinyin input, pinyin is input in the Pinyin input area in alphabet, and when character input is performed by Japanese reading input, kana is input in the Japanese reading input area. Which input area is used can be selected with the up and down keys of the cursor key 16. When the user directly inputs characters into the input area 30a, the operation mode of the electronic dictionary device 1 becomes the direct input mode.

  The Chunichi Dictionary initial screen 30 has a menu selection area 30b. In the menu selection area 30b, for example, “Jukugo search”, “Search by radical or number of strokes”, “Related box article”, and the like are displayed, and the user selects Pinyin input and Japanese reading by selecting from the displayed items. Input other than input can be performed. The present invention is characterized by the input process of kanji in the phrase input mode when the user selects “search phrase” from the menu. If the user selects “Search by radical or number of strokes” from the menu, the operation mode becomes the radical / stroke number input mode. The selection from the menu is determined by pressing the number key corresponding to the number (selection number) given to the item that the user wants to select, or highlighting the selection number that the user wants to select with the up and down keys of the cursor key 16. Selection can be made by pressing the key 15.

  When “Jukugo Search” is selected from the items displayed in the menu selection area 30b in the state where the Chunichi Dictionary initial screen 30 is displayed, the phrase input mode 31 is entered, and the phrase input screen 31 shown in FIG. It is displayed on the display unit 11. Here, a case where “an” is input as the first character will be described. The idiom input screen 31 has an input menu selection area 31a and an input character display area 31b. If the numeric key “1” key is pressed while the Chunichi Dictionary initial screen 30 is displayed, an idiom input screen 31 is displayed. In the input menu selection area 31a, as the selection items, “input first character” (selection number “1”), “input second character” (selection number “2”), “third” "Enter characters" (selection number "3") and "Start search" (selection number "4") are displayed. Note that items that are grayed out in the selection items, in this example, “enter second character”, “enter third character”, and “start search” can be currently selected. Indicates that it is not possible. When the phrase input screen 31 is first displayed, the phrase used as a search key is not input, and the search process cannot be performed. Therefore, “start search” cannot be selected. Also, in order to facilitate the search process, it is desirable to input in order from the first character. Therefore, when the previous character is not input, “2” cannot be input so that the next character cannot be input. “Input third character” and “input third character” cannot be selected.

  The input character display area 31b has a first character display area 310, a second character display area 311, and a third character display area 312. Kanji characters input by a kanji input process described later are displayed in each area. . When the idiom input screen 31 is first displayed, no character is input, so no kanji is displayed in the input character display area 31b. In the present embodiment, the number of characters that can be input is described as three characters. However, the number of characters that can be input is not limited thereto, and may be two characters or may be four or more characters. If the number of characters is other than three, the display of the input menu selection area 31a and the input character display area 31b, the number of times of each process described later, and the like may be appropriately changed according to the number of characters.

  When the phrase input screen 31 is displayed, the user presses the numeric key “1” or presses the enter key 15, so that the user can select “first character” which is an item displayed in a solid line. When “input” (selection number “1”) is selected, a Chinese character input screen 32 shown in FIG. 4C is displayed. On the Chinese character input screen 32, a Chinese character search method selection area 32a is displayed. The kanji search method selection area 32a includes a Japanese reading input area 320, a radical reading input area 321, a radical stroke number input area 322, and a total stroke number input area 323 as selection items. In the kanji search method selection area 32a, a selection symbol 32b and a cursor 32c indicating the selected input area are displayed.

  The user can select the kanji search method by pressing the up / down key of the cursor key 16 to display the selection symbol 32b and the cursor 32c in any of the input areas. At the initial time point when the kanji input screen 32 is displayed, the Japanese reading input area 320 is selected, the cursor 32c is displayed, and the selection symbols 32b are displayed on both sides of the Japanese reading input area 320. . For example, each time the user presses the down key, the selection symbol 32b and the cursor 32c are displayed from the Japanese reading input area 320 to the radical reading input area 321, the radical number input area 322, and the total stroke number input area 323. Move in the order.

  Here, a case where search by Japanese reading is selected as the kanji search method will be described. When the selected symbol 32b and the cursor 32c are displayed in the Japanese reading input area 320 and the character key is pressed and "An" is input, as shown in the Chinese character input screen 33 in FIG. "An" is displayed in the Japanese reading input area 330 of the method selection area 33a. The selection symbol 33 b and the cursor 33 c remain displayed in the Japanese reading input area 330. Here, when the enter key 15 is input, the Chinese character dictionary data stored in the dictionary database unit 23 is searched using “An” as a search key. As a search result, as shown in the candidate kanji display screen 34 in FIG. 4E, candidate kanji whose Japanese pronunciation matches “an” is displayed in the list display area 34a. In FIG. 4E, four candidate Chinese characters are displayed with selection numbers. The candidate Kanji display screen 34 has a page number display area 34b. In the page number display area 34b, the total number of pages and the displayed page are displayed as displayed page / total number of pages. When there are a large number of candidate Chinese characters in the search results, it is not possible to display all candidates on one screen, so it is necessary to display them in a plurality of screens. One screen divided into a plurality of pages constitutes one page, and the quotient obtained by dividing all the candidate kanji numbers by the number of display kanji characters per page (15 characters in this embodiment) is the total number of pages. When there is a remainder in division, the total number of pages is the quotient + 1 page. Among candidate Chinese characters, each page is displayed such that 1 to 15 characters are the first page, 16 to 30 characters are the second page, and 31 to 45 characters are the third page. For example, when the up / down key of the cursor key 16 is pressed, the display page can be forwarded and returned. In the candidate kanji display screen 34 in FIG. 4 (e), the number of candidate kanji is four, so the total number of pages is one page, and the currently displayed page is also the first page. In the page number display area 34b, “ 1/1 "is displayed.

  Since the kanji to be input as the first character is “cheap” (selection number “1”), the number key “1” is pressed or the cursor key is displayed while the candidate kanji display screen 34 is displayed. By depressing 16, the selection number “1” is highlighted and depressing the decision key 15 selects “Kan” as the first character, and the idiom input screen 35 shown in FIG. Is displayed. The idiom input screen 35 has an input menu selection area 35a and an input character display area 35b. In the input menu selection area 35a, as selection items, “input first character” (selection number “1”), “input second character” (selection number “2”), “third” "Enter characters" (selection number "3") and "Start search" (selection number "4") are displayed. Of the selection items, “input third character” (selection number “3”) is grayed out, indicating that it cannot be currently selected. When the first Kanji character is input, at least the search key has been input and search processing can be performed, so that “start search” can be selected. In addition, since the second Kanji character has not been input, “input third character” cannot be selected.

  The input character display area 35b has a first character display area 350, a second character display area 351, and a third character display area 352. When the first character is input, the first character display area “Low” is displayed in 350. Kanji characters are not displayed in the second character display area 351 and the third character display area 352.

  FIG. 5 is a diagram showing an example of a display screen when inputting Chinese characters. Hereinafter, a character input procedure for inputting the second Chinese character will be described with reference to FIG. Here, a case where “謐” is input as the second Kanji character will be described.

  When the phrase input screen 35 is displayed, the user is displayed as a solid line by pressing the numeric key “2” or highlighting the selection number “2” and pressing the enter key 15 When the item “input second character” (selection number “2”) is selected, a Chinese character input screen 41 shown in FIG. 5A is displayed. On the Chinese character input screen 41, a Chinese character search method selection area 41a is displayed. Similar to the kanji input screen 32 shown in FIG. 4C, the kanji search method selection area 41a includes, as selection items, a Japanese reading input area 410, a radical reading input area 411, a radical number input area 412, and a total stroke. A number input area 413 is provided. In the kanji search method selection area 41a, a selection symbol 41b and a cursor 41c indicating the selected input area are displayed.

  At the initial time point when the kanji input screen 41 is displayed, the Japanese reading input area 410 is selected, the cursor 41c is displayed, and the selection symbols 41b are displayed on both sides of the Japanese reading input area 410. .

  Here, a case where search by radical reading is selected as the kanji search method will be described. When the lower key of the cursor key 16 is pressed while the kanji input screen 41 is displayed, a kanji input screen 42 shown in FIG. 5B is displayed. In the kanji search method selection area 42a, the selection symbol 42b and the cursor 42c are displayed in the radical reading input area 421, and the search by radical reading is selected as the kanji search method. Here, when the character key is pressed and “Gonben” is input, as shown in the kanji input screen 43 in FIG. 5C, the radical reading input area 431 of the kanji search method selection area 43a includes: “Gonben” is displayed. The selection symbol 43b and the cursor 43c remain displayed in the radical reading input area 431. Here, when the determination key 15 is pressed, the kanji dictionary data stored in the dictionary database unit 23 is searched using “Gonben” as a search key. As a search result, as shown in the candidate kanji display screen 44 of FIG. 5D, candidate kanji whose radical is “Ganben” is displayed in the list display area 44a. In the page number display area 44b, “1/12” is displayed, and it is understood that the total number of pages is 12, and the first page is being displayed. Since “謐” to be input as the second character is not displayed on the first page, the lower key of the cursor key is pressed, as shown in the candidate character display screen 45 in FIG. The page is fed until “謐” is displayed in the list display area 45a. This page is the ninth page because “9/12” is displayed in the page number display area 44b.

  While the Chinese character “謐” (selection number “6”) is displayed in the list display area 45a, the numeric key “6” is pressed or the cursor key 16 is pressed to select the selection number “6”. "Is highlighted and" OK "is selected as the second kanji character by pressing the enter key 15, and the phrase input screen 46 shown in FIG. 5 (f) is displayed. In the input menu selection area 46a, as the selection items, “input first character” (selection number “1”), “enter second character” (selection number “2”), “third” "Enter characters" (selection number "3") and "Start search" (selection number "4") are displayed.

  The input character display area 46b has a first character display area 460, a second character display area 461, and a third character display area 462. When the second character is input, the first character display area “Low” is displayed in 460, and “謐” in Chinese is displayed in the second character display area 461. Kanji characters are not displayed in the third character display area 462.

  Since “Anjo”, which is an idiom for search purposes, has been input, whether the numeric key “4” is pressed while “Anjo” is displayed in the input character display area 46b of the idiom input screen 46 Alternatively, the cursor key 16 is pressed to highlight the selection number “4” in the input menu selection area 46a, and the determination key 15 is pressed to select “start search” (selection number “4”). The Chinese-Japanese dictionary data stored in the dictionary database unit 23 is searched by using “Anjo” as a search key.

  FIG. 6 is a diagram showing an example of a display screen of phrase search results. The search result of the phrase search is displayed as a candidate phrase in the list display area 51a as shown in the candidate phrase display screen 61 of FIG. In the figure, only “Anjo” (selection number “1”) is displayed as a candidate idiom, but this is because there is only one candidate that matches the search key, and there are a plurality of candidates as a result of the search. In this case, all are displayed in the list display area 51a.

  In the state where the candidate phrase display screen 51 is displayed, the numeric key “1” is pressed or the selection number “1” is already highlighted. (Selection number “1”) is selected, and the idiom information display screen 52 shown in FIG. 6B is displayed. The idiom information display screen 52 has a idiom information display area 52a on which “Anhui” pinyin and kanji notation, their meanings and examples are displayed.

  As described above, when entering a kanji, one kanji can be determined based on the kanji reading, the total number of kanji strokes, the radical reading, the number of strokes, etc. That is, the idiom can be input.

  This allows you to enter kanji words that contain both kanji that you don't understand and kanji that you don't know about radicals if you know any of the kanji search information. Kanji can be entered.

  When inputting a Chinese idiom, it can be input based on Japanese reading and so on, so even a user who does not know Chinese Pinyin can input. In addition, since an idiom of two or more characters can be input and searched using this as a search key, search result candidates can be narrowed down and the operation is simplified.

  In the above example, a search by Japanese reading is performed as a kanji search method for the first character “A”, and a search by radical reading is performed as a kanji search method for the second character “謐”. As shown in the figure, a search based on the number of radicals and a search based on the total number of strokes are possible as shown in the kanji search method selection area on the kanji input screen.

  FIG. 7 is a diagram illustrating an example of a display screen when inputting Chinese characters. Hereinafter, as a kanji search method when inputting the second character “謐”, a character input procedure in the case of performing a search based on the number of radical strokes will be described with reference to FIG.
