Abstract

PROBLEM TO BE SOLVED: To eliminate the possibility of misoperation at the time of connection of a character string. SOLUTION: If there is no corresponding index word after a processing was started and the retrieval of an input character string has been completed in a step (1), it is judged in a step (2) whether or not the input character string includes a code representing a tone of, for example, one of '0' to '4' and '-'. When the code is found in the step (2) (YES), the code of '0' to '4' and '-'in the character string is deleted in a step (3) and a return to an input screen in a step (4) to make corrections. When the code is not found in the step (2) (NO), a return to the input screen is made as it is in the step (4) to make corrections.

The above steps [83, 84, 85] are omitted.

As described above, in the above-described search device 70, for example, a description sentence corresponding to the input index word is searched, the history of the input index word is stored, and the search using the history list is executed. In addition, the storage and maintenance of these history data are performed.

However, in the above-described search device 70, when an attempt is made to input a Chinese index word, for example, in a Chinese Pinyin search, it is necessary to input a so-called four-tone tone. That is, in the Chinese Pinyin search, the four vowels are represented by, for example, four types of symbols as shown in FIG. No symbol is added to a light vowel without tone.

On the other hand, in the above-described retrieval apparatus such as an electronic book player, for example, as shown in FIG. I did it. That is, in this example, "0" is used for a light vowel without tone, "1" is used for a vowel of one voice, "2" is used for a vowel of two voices, and "3" is used for a vowel of three voices. "4" is added to the vowel of to represent four voices.

On the other hand, in the above-described retrieval apparatus such as an electronic book player, for example, when there is an error in the input character string, for example, the backward "←" key of the cursor movement keys 97 is operated. By doing so, characters are deleted one by one from the end of the character string. Therefore, for example, the character string “AB1CD” as shown in FIG.
To correct the third “1” of “EF4”, use the backward “←” key to “4FEDC1” from the end of the character string.
Will be deleted and corrected.

However, when such correction is performed, for example, when the above-mentioned tone code is included, the number of characters to be deleted increases by the amount of the code. In such deletion of characters, if the number of characters differs from the original number of characters, such as when a tone code is included, an operation error is likely to occur. In particular, when the same backward "←" key is repeatedly operated as described above, the number of times of operation cannot be understood, and erroneous operation is likely to occur.

The present application has been made in view of the above points, and the problem to be solved is that the conventional apparatus uses an index word with a tone such as Chinese Pinyin search. When performing a search, an erroneous operation is likely to occur due to correction of an input character string.

[0040]

For this reason, in the present invention, when correcting an input, a sign relating to a tone is removed from the display of the input. Correction is made to the error, thereby eliminating the risk of erroneous operation.

[0041]

DESCRIPTION OF THE PREFERRED EMBODIMENTS That is, according to the present invention, a storage medium in which a plurality of pairs of index words and explanatory sentences corresponding to the index words are stored is mounted, and input means for inputting the index words and input means for inputting the index words are provided. Search means for searching for an explanatory note corresponding to the searched index word, wherein the storage medium is searched by the input index word, and an explanatory note corresponding to the searched index word is displayed. In addition to inputting a predetermined code related to tone to the index word by the input means and performing input, when correcting this input, display is performed by removing a predetermined code related to tone from the display of the input. is there.

Hereinafter, the present invention will be described with reference to the drawings. First, in the retrieval apparatus of the present invention, a key for inputting a tone is provided in the above-described key input device 72 shown in FIG. 5, for example. The tone input key is used, for example, by changing the function of the character enlargement key 99 described above, for example, by transferring a program provided in the electronic book 73 to the main RAM 86.

In the retrieval apparatus of the present invention, when the tone is unknown, a specific code, for example, "-" is added instead of the tone code, for example, "0" to "4", and an index word is input. It is determined as follows. The character string input in this way is searched. Further, for example, when there is an error in the input character string, the character is deleted one by one from the end of the character string by operating, for example, the backward "←" key of the cursor movement keys 97. ing.

FIG. 1 is a flowchart showing an example of the processing performed by the search device to which the present invention is applied.

In FIG. 1, the process is started,
If the search for the input character string is completed in step [1] and there is no corresponding index word, in step [2], for example, tones "0" to "4" and "-" are represented in the input character string. It is determined whether there is a sign.

If there is a sign in step [2] (YES), the signs "0" to "4" and "-" in the character string displayed in step [3] are deleted, and step [4] ] To return to the input screen to make correction. If there is no code in step [2] (NO), the process returns to the input screen in step [4] and correction is performed.

Thus, in this apparatus, when correcting the character string "AB1CDEF4" as shown in FIG. 2A, for example, the character strings are displayed as "0" to "4" as shown in FIG. "ABCD" with the sign of "-" removed
EF ". For example, when it is desired to correct the third “1”, “FEDC” is deleted from the end of the character string by the backward “←” key, and the correction is performed.

In this case, since the number of characters becomes equal to the number of original characters, the risk of erroneous operation can be reduced. In particular, as described above, when the same backward “←” key is repeatedly operated, the number of operations is reduced, so that the risk of erroneous operation can be reduced.

Further, a search is performed again in a state where the code of the input character string has been deleted. For example, in the case of an error in only the tone code, an index word is obtained by the search and the search is successful. And the likelihood of a search becoming "not applicable" can be reduced.

Therefore, in this device, when correcting the input, by removing the sign relating to the tone from the display of the input, the correction is performed on the original character string,
The possibility of erroneous operation can be eliminated.

As a result, in the conventional apparatus, when an index word is searched with a tone such as a Chinese Pinyin search, there is a problem that an erroneous operation is easily caused by correcting an input character string. According to the present invention, such a problem can be solved, and in particular, when the same key is repeatedly operated, it is possible to eliminate the possibility that the number of operations is not understood and erroneous operation is likely to occur. it can.

Further, a search is performed again in a state where the code of the input character string is deleted, and, for example, in the case of an error of only the tone code, an index word is obtained by the search and the search is successful. And the likelihood of a search becoming "not applicable" can be reduced.

Thus, according to the above-described retrieval apparatus, a storage medium storing a plurality of pairs of index words and explanatory sentences corresponding to the index words is mounted, and the input means for inputting the index words and the input means for inputting the index words. Search means for searching for an explanatory note corresponding to the searched index word, wherein the storage medium is searched by the input index word, and an explanatory note corresponding to the searched index word is displayed. The input means adds a predetermined code relating to the tone to the index word and performs the input, and when correcting this input, the display can be performed by removing the predetermined code relating to the tone from the display of the input. It is.

[0054]

According to the present invention, when the input is corrected, the sign relating to the tone is removed from the display of the input, so that the original character string is corrected and the possibility of erroneous operation is eliminated. You can now.

As a result, in the conventional apparatus, when an index word is searched with a tone such as a Chinese Pinyin search, there is a problem that an erroneous operation is easily caused by correcting the input character string. According to the present invention, such a problem can be solved, and in particular, when the same key is repeatedly operated, it is possible to eliminate the possibility that the number of operations is unknown and erroneous operation is likely to occur. You can do it.
