Abstract

PURPOSE:To correct characters without requiring excessive load by providing the title system with a voiced sound symbol (VSS)/semivoiced sound symbol (SSS) added character restoring function for substituting a character to which a VSS or an SSS is added to a character to which no VSS or SSS is added. CONSTITUTION:A character string inputted by a user is held in a character input part 1. The character string is edited by a character string editing part 2 and the edited character string is displayed by a character string display part 3. Whether a VSS or an SSS is added to the final character of the Japanese character string already inputted by the user or not is decided by referring a VSS/SSS added character corresponding table 5. When the decided result is YES, the table 5 is referred by using the final character as a retrieving key to retrieve characters and a character corresponding to the key is extracted. Then, the final character of the input character string is rewritten by the extracted character by a VSS/SSS added character string restoring part 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a Japanese word processing method, and particularly to a Japanese input method suitable for a kana input method that improves usability.

[Conventional technology]

As described in the document editing device of Japanese Patent Application Laid-Open No. 62-84369, characters to which a voiced or handakuten mark is to be added are automatically determined when editing a document, and only the voiced or handakuten mark is input. Techniques are known that make it possible to add voiced or handakuten characters to characters.

[Problem to be solved by the invention]

The above-mentioned conventional technology only adds voiced or handakuten to previously input characters;
It is not possible to modify characters that do not have voiced or half-voiced marks. In addition, when inputting Japanese, it is still necessary to delete the voiced and half-voiced characters that you want to correct and then input the same characters again, which is an inconvenient Japanese input method that puts a burden on the user. It is.

An object of the present invention is to provide an easy-to-use input method that places as little burden on the user as possible.

[Means for solving problem S]

The above purpose is to determine whether a character can be added with a voiced or handakuten when modifying a character to which a voiced or handakuten can be added, without deleting the character to which a voiced or handakuten is added. With the voiced and handakuten character string return function, which replaces characters with voiced or handakuten with characters without voiced or handakuten,
achieved.

[Operation] First, a character to which a voiced or handakuten is to be added and a character to which a voiced or handakuten corresponding to the character is added are registered in the voiced and handakuten added character correspondence table.

Next, when modifying a character to which a voiced or handakuten is added, if the input key is the back key and the last character of the input string is a character to which a voiced or handakuten is added, the voiced mark is・Refer to the handakuten added character correspondence table, extract the corresponding character to which the dakuten or handakuten is not added, and replace it with the character to which the dakuten or handakuten is added, which is the target of correction.

With the above method, one character can be corrected without deleting the character to be corrected.
