[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic dictionary and an electronic dictionary display method that include a dictionary in which words and their meanings are registered, and that output the meaning of input words.
[0002]
[Prior art]
The electronic dictionary has a dictionary in which tens of thousands of words are stored. When a spelling is input using a keyboard or the like, the meaning of the word is displayed and a plurality of words after that word are output in alphabetical order as headwords. It has become. Here, FIGS. 14 and 15 are conceptual diagrams for explaining tables and dictionary data stored in the internal ROM of a conventional electronic dictionary. FIG. 16 is a flowchart for explaining the operation of the system.
[0003]
When the power is turned on, the user inputs a word in step Sa1 shown in FIG. Next, in step Sa2, headword data “about” stored in the head address A0 of the headword table TBL1 shown in FIG. 14 is read and set as a search word. Next, in step Sa3, the input character string input by the user in step Sa1 is matched with the search word read in step Sa2, and then it is determined whether or not both match in step Sa4.
[0004]
If the input word matches the search word, the process proceeds to step Sa5, and the body address data of the matched search word is acquired from the headword table TBL1 shown in FIG. For example, if the matched search word is “about”, the body address data “a0” shown in FIG. 14 is acquired. Next, in step Sa6, the body data of the address of the body address data shown in FIG. 15 is displayed. For example, when the text address data is “a0”, the text data “about [previous]... Around [. After the display, the process returns to step Sa1 again to enter the user character input mode.
[0005]
On the other hand, if the character string (word) input by the user does not match the search word read in step Sa2 in step Sa4, the process proceeds to step Sa7, and the next address is stored in the headword table TBL1 shown in FIG. It is determined whether there is headword data. If there is next headword data, the process proceeds to step Sa8, and the next headword data in the headword table TBL1 shown in FIG. 14 is set as a search word. For example, if the search word so far is “about”, the next headword data “act” is set as the search word. Thereafter, the process returns to step Sa3 to determine whether or not the newly set search word “act” matches the user input word. Thereafter, the above-described processing is repeated until the search word matches the user input word.
[0006]
If there is no entry word data at the next address in step Sa7, the process proceeds to step Sa9. In this case, as a result of comparing all the input word data of the user and the headword data shown in FIG. 14, there is no match, so in Step Sa9, a message “No corresponding word” is displayed to the user. Notify that the input word is not in the dictionary. After the message is displayed, the process returns to step Sa1 to enter the user character input mode.
[0007]
[Problems to be solved by the invention]
By the way, it is more convenient for a specific user such as a junior high school student or a high school student to search on a textbook page or the like, for example, rather than inputting alphabetically. Also, in terms of output, it is more convenient for words to be output in the order of textbooks than in alphabetical order. Some words have multiple meanings, but it is not always clear which meaning is appropriate.
[0008]
To solve the above problem, there is a method of creating an electronic dictionary dedicated to the specific user. However, junior high school and high school users need to re-create and re-purchase electronic dictionaries each time, such as the academic year going up every year or the textbook itself being revised every three years. Both have the problem of high costs.
[0009]
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an electronic dictionary and an electronic dictionary display method capable of displaying headwords in an order more suitable for the user and displaying corresponding text data. It is said.
[0010]
In order to solve the above-described problem, the present invention includes a search term table in which a plurality of search terms and addresses of body data corresponding to these search terms are associated with each other, and the search term table Storage means for storing a display order table that defines a display order for displaying search terms, and a plurality of division tables in which the display order defined in the display order table is divided into groups according to different division criteria ; The search method selection means for the user to select either search or partial search, and when the full search is selected in the search method selection means, the user selects the search based on the contents described in the search word table. A user selects all search means for searching and displaying text data corresponding to an input search word, and any one of the plurality of division tables. A partition table selecting means for-option, and a group specifying means for a user to specify one of a plurality of groups divided by the selected classification table by the segment table selecting unit, partial search in the search method selection means Is selected, it is included in the group designated by the group designating means among the plurality of groups sorted by the selected sorting table, regardless of which sort table is selected by the sort table selecting means . Display a list of some of the search terms described in the search term table in accordance with the display order defined in the display order table, and select a specific list from the displayed list. When a search word is selected by the user, the body data corresponding to the selected search word is searched and displayed. Characterized in that it comprises a partial search means.
[0011]
According to the present invention, to display the search term in accordance with the display order defined in advance in the display sequence table, the specific search word in the search word is the display is selected, the search word is the selected display the corresponding text data. Therefore, if the display order of the display order table is defined according to the purpose of the user, the search terms can be displayed in an order more suitable for the user, and the corresponding body data can be displayed.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
[0013]
A. Configuration of Embodiment A-1. 1 is a block diagram showing a configuration of an electronic dictionary according to an embodiment of the present invention. In the figure, the electronic dictionary is composed of a CPU 1, a built-in ROM 3, an external ROM 4, a keyboard 5 and a display 6, which are connected to each other via a data bus 2. The CPU 1 performs overall control by a control program stored in the built-in ROM 3. The built-in ROM 3 stores the control program, body data, font data, and headword table TBL1. The text data stored in the built-in ROM 3 is the same as the text data shown in FIG. 15 of the prior art, and the headword table TBL1 is the same as the headword table TBL1 shown in FIG. 14 of the prior art. It is. The keyboard 5 includes a plurality of keys, detects input of the keys, and supplies the detected keys to the CPU 1. The CPU 1 operates each function with the input key.
[0014]
The external ROM 4 is detachable, and when attached, is connected to the data bus 2 like the built-in ROM. The external ROM 4 stores a page table TBL2 shown in FIG. 3 and a headword table TBL3 shown in FIG. The page table TBL2 of the external ROM 4 stores a page such as a textbook and headword table address data in association with each other. The headword table TBL3 of the external ROM 4 stores the headword table address and headword address data in association with each other.
[0015]
For example, for the headwords appearing on one page, addresses “A10000” to “A10006” in the headword table TBL3 of the external ROM 4 correspond. The address “A10000” corresponds to headword address data “A1”, the address “A10001” corresponds to headword address data “A1005”,. The headword address data indicates the address of the headword table TBL1 in the built-in ROM 3 shown in FIG. Therefore, by using the page table TBL2 and the headword table TBL3 in the external ROM 4, it is possible to search and display the order of words appearing on the page in the order of pages of textbooks and the like.
[0016]
Which of the internal ROM 3 and the external ROM 4 is used is selected by key input from the keyboard 5. When the external ROM 4 is selected, the CPU 1 sets the address of the text data (text data) to be displayed based on the code input from the keyboard 5, the page table TBL 2 stored in the external ROM 4, and the headword. After calculating from the table TBL3, the body data at the address is read from the built-in ROM 3, and the font data stored in the built-in ROM 3 corresponding to each character is transferred to the display (dot matrix) 6 to obtain the body data. The characters are displayed.
[0017]
Next, FIG. 2 is a conceptual diagram showing the appearance of the electronic dictionary described above. It should be noted that portions corresponding to those in FIG. In the figure, the keyboard 5 includes an alphabet key 7, a power button 8, a set key 9, a translation key 10, a menu key 11, and a cursor key 12. The alphabet key 7 is used for the user to input words and commands. The power button 8 turns on / off the power to the electronic dictionary. The set key 9 is used for confirming the input word. The translation key 10 is used to execute translation for the input word. The menu key 11 is used to call up a menu for selecting an electronic dictionary function or the like. The cursor keys 12 are divided into upper, lower, left and right, and are used when the cursor displayed on the display 6 is moved and the displayed function or character string is selected. Further, the housing is provided with an insertion port 13 for mounting the external ROM 4.
[0018]
B. Operation of Embodiment Next, the operation of the electronic dictionary according to the present embodiment will be described. 5 to 8 are flowcharts for explaining the operation of the electronic dictionary. FIG. 9 is a conceptual diagram showing, as an example, words appearing on a textbook page in the order of appearance, and FIG. 10 is a conceptual diagram showing screen transition on a display. When the power is turned on, first, in step Sb1, the user selects either the entire dictionary search or the textbook search. At this time, the screen of the display 6 is displayed as shown in FIG. The arrow on the screen is a “cursor”, which is moved by operating the cursor key 12. The function is selected by operating the set key 9. Here, if the whole search is selected, the process proceeds to step Sb2, and a conventional dictionary search (see FIG. 16) is performed.
[0019]
On the other hand, if textbook search is selected, the process proceeds to step Sb3, and the user is made to input a textbook page on which the word to be searched is posted. At this time, the screen of the display 6 is displayed as shown in FIG. Next, after the number of pages input in the first line of the display 6 is displayed in step Sb4, an arrow (cursor) is displayed in the second line of the display 6 in step Sb5. Next, in step Sb6, entry word table address data stored corresponding to the page input by the user is acquired from the page table TBL2 of the external ROM 4 shown in FIG. For example, when the user inputs one page, the headword table address data is “A10000”.
[0020]
Next, in step Sb7, the entry word table TBL3 of the external ROM 4 shown in FIG. 4 is accessed with the address (addr) of the entry word table address data acquired in step Sb6, and the entry word address data stored at that address. To get. For example, if the headword table address data is “A10000”, “addr = A10000” is obtained, and the headword address data is “A1”.
[0021]
Next, the process proceeds to step Sb8 shown in FIG. 6, and the entry word table TBL1 stored in the built-in ROM 3 shown in FIG. 14 is accessed with the address of the entry word address data, and the entry word data stored at that address. And the headword data is displayed on the display 6. For example, if the headword address data is “A1”, the headword “act” corresponding to the address “A1” is displayed.
[0022]
Next, in step Sb9, it is determined whether or not headwords are displayed for the number of screen lines of the display 6. In this embodiment, the number of textbook pages corresponding to the first line, and the English words appearing on that page after the second line are displayed, one word per line, for the number of lines on the screen. Yes. Then, when the number of words is not displayed for the number of lines on the screen, the process proceeds to step Sb10, and it is determined whether there is still a headword on the page in addition to the currently displayed word. This determination is made by referring to the page table TBL2 of the external ROM 4 shown in FIG. 3, and the address of the headword next to the currently displayed headword is the headword table address of the next page of the currently displayed page. This is done by comparing whether or not they are the same. If they are the same, the next headword is the headword of the next page, so that the headword currently displayed is the last headword of the page.
[0023]
For example, if the headword currently displayed is “act”, the address of the next headword is “A10001” from the headword table TBL3 in the external ROM 4 shown in FIG. Further, since the currently displayed page is the first page, the headword table address of the next page is “A10007” from the page table TBL2 of the external ROM 4 shown in FIG. Therefore, since these addresses are not equal, it can be seen that there is still a headword on the page (first page) in addition to the currently displayed word.
[0024]
If the headword of the page still remains, the process proceeds to step Sb11, and the address (addr) is set to the next address of the headword table TBL3 of the external ROM 4 shown in FIG. For example, if the address (addr) before proceeding to step Sb11 is “A10000”, the next address is “A10001”.
[0025]
Next, in step Sb12, the entry word address data stored in the address (addr) is acquired from the entry word table TBL3 of the external ROM 4 shown in FIG. For example, if “addr = A10001”, the acquired headword address data is “A1005”. Thereafter, the process returns to step Sb8, and the headword data at the address of the headword address data acquired in step Sb12 is displayed. Thus, the headwords for one screen are displayed by repeatedly executing Steps Sb8 to Sb12. At this time, the screen of the display 6 is displayed as shown in FIG.
[0026]
On the other hand, if the currently displayed headword is the last headword of the page in step Sb10, the process proceeds to step Sb13, and the headword display is terminated. In addition, when headwords corresponding to the number of screen lines are displayed in step Sb9, the process proceeds to step Sb13, and the display of headwords is terminated.
[0027]
In step Sb13, a key input from the user is awaited. When there is a key input, each process is executed according to the input key. For example, when the lower key of the cursor key 12 is operated, the process proceeds to step Sb15 shown in FIG. 7, and when the translation key 10 is operated, the process proceeds to step Sb shown in FIG. If any other key is operated, the process proceeds to step Sb14, and processing corresponding to the input key is executed.
[0028]
First, a case where the lower key of the cursor key 12 is operated will be described. If the down key is operated, it is determined in step Sb15 shown in FIG. 7 whether or not the arrow (cursor) is at the bottom of the screen. If the arrow (cursor) is not yet at the lowest level, the process proceeds to step Sb16, and the arrow (cursor) is moved down by one level. Then, it returns to step Sb13 and waits for the key input from a user again.
[0029]
On the other hand, if the arrow (cursor) is at the bottom, the process proceeds to step Sb17, and whether or not there is a headword on the page in addition to the currently displayed word, as in step Sb10 described above. Determine whether. If there is still a headword, the process proceeds to step Sb18, and the address (addr) is set to the next address of the headword table TBL3 in the external ROM 4 shown in FIG. 4 as in step Sb11 described above. Next, in step Sb19, headword address data stored in the set address (addr) is acquired.
[0030]
Next, after clearing the screen of the display 6 in step Sb20, a page is displayed on the first line of the display 6 in step Sb21, and an arrow (cursor) is displayed on the second line in step Sb22. Thereafter, the process returns to step Sb8 shown in FIG. In this way, when the user operates the down key, the arrow (cursor) reaches the bottom of the screen, and there is still a headword on the page, the address next to the bottom headword address starts again. Displays as many headwords as the number of lines on the screen.
[0031]
On the other hand, if the page does not have an entry word in step Sb17, the process returns to step Sb13 and waits for a key input from the user again without changing the screen.
[0032]
Next, a case where the translation key 10 is operated will be described. When the translation key 10 is operated in step Sb13, the process proceeds to step Sb23 shown in FIG. 8, and an arrow (cursor) at the time when the translation key 10 is operated from the entry word table TBL1 of the built-in ROM 3 shown in FIG. Get the text address data of the headword pointed to. For example, when the arrow (cursor) points to the headword “act”, the acquired body address data is “a1”.
[0033]
Next, in step Sb24, the text data (see FIG. 15) corresponding to the address of the text address data is read and displayed on the display 6. For example, if the text address data is “a1”, the text data “act [name] act / action [other] perform [self] do” of the address “a1” is displayed on the screen. At this time, the screen of the display 6 is displayed as shown in FIG. Thereafter, in step Sb25, the display is maintained until a key is pressed by waiting for key input. When any key is pressed, processing corresponding to the key is executed in step Sb26.
[0034]
As described above, according to the above-described embodiment, the external ROM 4 to which the headword table TBL3 for designating only the words necessary for the user can be attached to and detached from the body data of the built-in ROM 3, and the use of the external ROM 4 is selected. In such a case, since the body data stored in the built-in ROM 3 corresponding to the headword specified in the headword table TBL3 is retrieved and displayed, only necessary words in the order useful for the user are displayed. Can be displayed. In addition, a page table TBL2 is provided that indicates the headword table TBL3 stored in the external ROM 4 in a specific way, in the embodiment in page order, and the body data in the built-in ROM 3 is changed according to the page table TBL2. Since it is made to search and display, the search suitable for a user can be performed. Further, since the display is performed according to the order of the page table TBL2, it is possible to display in the order more suitable for the user.
[0035]
In the case of a word having a plurality of meanings, the address of the body data shown in FIG. 14 is considered for each meaning as shown in FIG. 11, and the entry word table TBL3 in the external ROM 4 shown in FIG. As shown in FIG. 12, when the text data is displayed in step Sb24 shown in FIG. 8 as the headword table TBL4 having the semantic address for specifying the meaning, the semantic address data in the headword table TBL4 shown in FIG. The corresponding meaning may be reversed and displayed. In this case, only one meaning can be designated from a plurality of meanings. For example, when the word to be displayed is “act”, the semantic address data is “a1 + α4” from FIG. 12, and therefore the meaning of this page of this textbook is “[self] of the address“ a1 + α4 ”from FIG. " In this way, when a word has a plurality of meanings, a headword table TBL4 for selecting one of the plurality of meanings is provided in the external ROM 4, so that a word suitable for that case can be selected according to the headword table TBL4. Since the meaning can be instructed or displayed, the user can grasp the meaning of the word more easily.
[0036]
In the above-described embodiment, the search is performed in the page order of the textbook. However, by changing the section of the page table TBL2 shown in FIG. 3, the search can be performed not only in the page order but also in various divisions. . For example, as shown in FIG. 13, if the page table (section table) TBL5 is set in the section order, the search can be performed in the section order. Further, if a plurality of page tables TBL2 and TBL5 as shown in FIGS. 3 and 13 are provided and the user can arbitrarily select them, the page table TBL2 with a relatively small capacity shown in FIG. 3 is increased. Just do a search for various breaks.
[0037]
【The invention's effect】
As described above, according to the present invention, the search terms are displayed on the display means according to the display order defined in advance in the display order table, and the desired search terms among the displayed search terms are selected by the selection means. When selected, the text data corresponding to the selected search term is displayed on the display means. Therefore, if the display order of the display order table is defined according to the purpose of the user, it is more suitable for the user. There are advantages that the search terms can be displayed in order and the corresponding text data can be displayed.
