Abstract

PURPOSE:To improve the operability by holding the contents of a temporary storage means when dictionaries are changed and the attribute of a character retrieved in a dictionary before the change coincides with the attribute of a character retrieved in a dictionary after the change. CONSTITUTION:A dictionary number register 9 stored with a dictionary number indicating which of a KANJI(Japanese syllabary) dictionary 6, a Japanese- English dictionary 7, and an English-Japanese dictionary 8 is selected currently and an attribute register 10 stored with the attribute of the character retrieved in the currently selected dictionary are connected to a processing part 2. When the dictionary is changed by a dictionary selecting means, an attribute decision means decides whether or not the attribute of the character retrieved in the dictionary before the change coincides with the attribute of the character retrieved in the dictionary before the change. When not, an erasure control means erases the contents of a temporary storage means and when the attributes coincide with each other, the contents are held. Therefore, retrieval is carried out by using a character string including a character or character string which is inputted before the change as long as the attributes of the characters retrieved in the dictionary before and after the change coincide with each other.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has a plurality of dictionaries storing textual and linguistic information,
The present invention relates to an electronic dictionary in which any one of the dictionaries is searched by a character or a character string input into a temporary storage means as an input buffer.

[Prior Art] In general, an electronic dictionary is equipped with a dictionary such as an English-Japanese dictionary or a Japanese-English dictionary, and includes an input means such as a keyboard for inputting characters or character strings to be searched, and information input by the input means. a temporary storage means that is an input buffer for temporarily storing characters or character strings; a search means for searching a dictionary using the characters or character strings temporarily stored in the temporary storage means;
Display means such as a liquid crystal display for displaying the contents of the input buffer and the search results is provided.

Further, as a conventional electronic dictionary, an electronic dictionary is known that is equipped with a plurality of dictionaries and can selectively search for a desired dictionary using means such as a switching key.

[Problems to be Solved by the Invention] However, in conventional electronic dictionaries having such a configuration, if the dictionary is changed during or after inputting a character string to be searched, the data is stored in the temporary storage means. It was common for previously entered characters or strings to be cleared. Therefore, like the Japanese-English dictionary and the Kanji dictionary,
In both cases, even when the attribute of the search target character is Japanese, there is a problem in operability in that re-input using the input means is required.

The present invention was made with the aim of solving such problems, and when the dictionary is changed during or after inputting a character string, the previously inputted characters or The purpose is to provide an electronic dictionary that allows searching without re-entering character strings.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a method in which, when a dictionary is changed by a dictionary selection means, the attribute of the search target character in the dictionary before the change is changed to the search target character in the dictionary after the change. Attribute determining means for determining whether or not the attribute matches the attribute of the target character, and erasing control for erasing the contents of the temporary storage means if the result of this determination is that they do not match, and retaining the contents of the temporary storage means if they match. It is characterized by comprising means.

[Operation] In the electronic dictionary of the present invention, when the dictionary is changed by the dictionary selection means, the attribute is determined whether the attribute of the search target character in the dictionary before the change matches the attribute of the search target character in the dictionary after the change. The determination is made by the determination means. Further, as a result of this determination, if they do not match, the content of the temporary storage means is erased by the erasure control means, and if they match, the content of the temporary storage means is similarly retained by the erasure control means.

Therefore, if the dictionary is changed during or after inputting a character or character string using an input method, as long as the attributes of the search target characters in the dictionary before and after the change match, the character or character string input before the change will be changed. A search is performed using a string containing .

[Examples] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows the structure of an electronic dictionary according to an embodiment of the present invention.

In this figure, a processing section 2 that performs attribute determination and temporary memory deletion according to the features of the present invention is connected to an input section 1 such as a keyboard for inputting desired characters or character strings. A display control section 3 for controlling display of results and a display section 4 such as a liquid crystal display for displaying input characters and search results are connected in sequence.

Further, an input buffer 5 for temporarily storing characters or character strings input by the input unit 1 is connected to the processing unit 2. A dictionary is connected to search for characters or character strings. In this embodiment, there are three types of dictionaries connected to the processing unit 2: a kanji dictionary 6 that stores kanji information for kana information, and a Japanese-English dictionary that stores English information for Japanese information. 7, and an English-Japanese dictionary 8 that stores Japanese information for English information.

Furthermore, the processing unit 2 includes a dictionary number register 9 that stores as a dictionary number whether the currently selected dictionary is a Kanji dictionary 6, a Japanese-English dictionary 7, or an English-Japanese dictionary 8; An attribute register 1o for storing attributes of search target characters is connected.

Here, if the selected dictionary is the Kanji dictionary 6, the dictionary number DI C-Not,: rOJ is set, and if the selected dictionary is the Japanese-English dictionary 7, the dictionary number DI C-No is set to "1".
", if it is English-Japanese dictionary 8, the dictionary number DI C-N
Assuming that "2" is assigned to each o, for example, if the Japanese-English dictionary 7 is currently selected, the dictionary number register 9 will have r as the dictionary number DI C-NO.
lJ is stored.

Further, when searching the Kanji dictionary 6 and the Japanese-English dictionary 7, the attribute of the search target character is Japanese, and when searching the English-Japanese dictionary 8, this attribute is English.

Focusing on this, when the Kanji dictionary 6 and the Japanese-English dictionary 7 are selected, rOJ is assigned to the attribute ATTR, and when the English-Japanese dictionary 8 is selected, "1" is assigned to the attribute ATTR. Then, in the attribute register 10, for example, when the Japanese-English dictionary 7 is selected, 0 is stored as the attribute ATTR.

FIG. 2 shows a flowchart relating to the operation of this embodiment.

First, the operation is started by turning on the power, resetting the system, etc. (1 0 1). Immediately after starting 101,
First, the attribute ATT stored in the dictionary attribute register 10
“0” is initially set in R (1 0 2). Further 1 and
Dictionary number DIC stored in the dictionary number register 9
-NO is initialized to "0" and the memory contents of the input buffer 5 are cleared (1 0 3).

Next, the type of dictionary is displayed on the display screen of the display section 4 (104), and the state shifts to an input waiting state (105). Immediately after executing steps 101 to 103, step 103
is being executed, the dictionary to be selected is the Kanji dictionary 6. Therefore, at this time, the kanji dictionary 6 is displayed on the display screen of the display section 4 as the dictionary type related to selection. This display is performed, for example, by shading a predetermined area on the display screen of the display unit 4.

In the input holder 105, subsequent operations differ depending on the type of input key. When the input unit 1 is a keyboard, the difference in operation is whether the key pressed on the input holder 105 is ■Kanji key, ■Japanese-English key, ■English-Japanese key, or ■Character key. , ■Whether it is an “execute” key or not. Here, the Kanji key, the Japanese-English key, and the English-Japanese key are each provided as a single key on the input unit 1, and each is a key that indicates which dictionary is to be selected. Further, the character keys are keys representing kana characters, alphabets, numbers, etc., and the "execute" key is a key for executing a search operation.

(1) When the Kanji key is pressed In 105 above, the Kanji key is pressed (1 0 6
) and the attribute ATTR stored in the attribute register 10.
It is determined whether or not is "0" (1 0 7),
As a result of this determination, if it is determined that the attribute ATTR is not rOJ, the memory contents of the input buffer 5 are cleared (108); otherwise, the next step 10
Move on to 9. Further, even after the human buffer 5 is cleared in step 108, the process similarly moves to step 109.

In step 109, the dictionary number DI C-No stored in the dictionary number register 9 is set to "0", and in the next step 110, the attribute ATTR stored in the attribute register 10 is set to "0". " is set.

That is, when the Kanji key is pressed, rOJ is determined as the attribute ATTR of the input character or character string so that the Kanji dictionary 6 is selected as the dictionary to be searched. If the conventional attribute ATTR is not "0", the character or character string related to the conventional input, that is, the character or character string stored in the human buffer 5, cannot be used for the search, so only in this case Clear the contents of human buffer 5.

On the other hand, if the attribute ATTR related to conventional input is a value that allows the kanji dictionary 6 to be searched, that is, "0", it is possible to continue inputting without clearing the contents of the input buffer 5. It is possible.

(2) When the Japanese-English key is pressed When the Japanese-English key is pressed in the input holder 105 (1
1 In case 1), attribute ATTR as in case (1)
Determination 112 and clearing 113 of the input buffer 5 are performed as necessary. After this, the dictionary number register 9
The dictionary number DI C-No stored in is set, but in this case, the number DI C-No is set to "1" (1 1 4). Furthermore, the attribute register 10
"0" is set to the attribute ATTR stored in (1
1 5).

(3) When the English-Japanese key is pressed If the English-Japanese key is pressed (1 1 6), the above (1
), (2), attribute ATTR determination 117
, and clearing 118 of the input buffer 5 is performed as necessary. In this case, the dictionary number DI C-NO stored in the dictionary number register 9 is set to "2" (
1 1 9), and the attribute ATTH stored in the dictionary attribute register 10 is set to "1" (1 2 0
).

That is, when the English-Japanese dictionary 8 is selected as a search target, the input character or character string is an English character consisting of letters of the alphabet, etc., so the attribute ATT
Unlike in cases (1) and (2), "1" is set for H.

(4) When a character key is pressed If a character key is pressed (1 2 1), the character associated with the pressed key is stored in the input buffer 5 (1
22). The contents of the input buffer 5 are then displayed on the display section 4.

(5) When the "Execute" key is pressed After the desired character or character string is stored in the vJ reporter buffer 5 by repeating the above (4), when the "Execute" key is pressed (123), the corresponding A dictionary corresponding to the dictionary number DIC-No stored in the dictionary number register 9 is searched based on the characters or character strings stored in the person buffer 5 (1 2 4). After that, the search results are displayed on the display section 5 (1 2 5).

Note that after the operations (1) to (4) are performed, the display returns to the dictionary type display 104, and the display waits for input 105.
and waits for the next key input.

Therefore, for example, even if you search a kanji dictionary and then continue to enter the search target character ``It r'' in the English-Japanese dictionary or a part of it ``touta'' while the kanji dictionary is still selected, If you press the Japanese/English key after entering these character strings, the previously inputted "Touta" will be used as well as the previously inputted "Toutatsusuru" or the character input after this Japanese/English key input, "Tsuru". A search of the Japanese-English dictionary 7 is performed, and it is possible to obtain, for example, the English word "get" on the display screen of the display unit 4. Further, for example, if the dictionary is changed from the Kanji dictionary 6 to the English-Japanese dictionary 8 by pressing the English-Japanese key, the input characters that cannot be used before the change are erased by clearing the human buffer 5. It becomes possible to perform a search again using the characters or character strings input after that.

In addition, in this embodiment, in response to the selection of a dictionary, the attribute of the search string of the selected dictionary is set in an attribute register, and the attribute before change is obtained based on the contents of this register. However, it is also possible to detect the code information of the characters input to the human buffer and obtain the attributes before the change.

[Effects of the Invention] As explained above, according to the present invention, unnecessary input characters are cleared as the dictionary is changed between dictionaries with different attributes of search target characters, and the search target characters are Even if you change dictionaries between dictionaries with the same attributes,
You can perform a search using the characters entered before the change, improving operability.
