DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art Kana-kanji conversion means for converting a kana character string into a kanji-kana-kanji character string is generally used as an input means for a Japanese sentence mixed with kanji-kana in a task of preparing a document.

[0002] The present invention relates to a character processing device using kana-kanji conversion means.

[0003]

2. Description of the Related Art In a character processing apparatus having kana-kanji conversion means, general words are registered in advance in a conversion dictionary. For this reason, in normal document creation, by inputting kana characters and giving a conversion instruction,
You can create a sentence mixed with kanji and kana. However, operators vary widely, and words necessary for the user may not be registered. In addition, words unnecessary for the user may be registered. For this purpose, word registration means for registering necessary words and word deletion means are provided. For this purpose, the following methods have been proposed.

(1) A method of updating the conversion dictionary on the primary storage device every time a word is registered or deleted, and storing the word dictionary in the secondary storage device.

(2) A method in which the result of word registration or word deletion by a user is updated only in a conversion dictionary on a primary storage device such as a random access memory.

[0006]

However, in the case of the method (1), since the processing speed for storage is relatively low, it takes a long time to register a plurality of words.

In the case of the method (2), the conversion dictionary stored on the secondary storage device such as a disk is not updated. For this reason, another operation must be started to save, and the operation is complicated. In addition, since the saving operation must start a completely different saving operation from the word registration and the word deletion, the operator forgets to start the saving operation.
