Description of the Related Art In recent years, the spread of computers in office environments and the like has been remarkable, and almost all of the documents on documents handled in these office environments are created by document creation software operating on personal computers. . In recent computer systems, in consideration of the unique Japanese language form, such as the mixture of kana and kanji, instead of directly passing the character code input from the keyboard to document creation software, etc., Japan converts the character code input from the key to kana-kanji. The word input system can be converted to a FEP (Front En
d Processor), and the character code mixed with the kana-kanji characters converted by the Japanese input system is delivered to document creation software or the like.

In this Japanese input system, whether a key input code is handled as "kanji", "half-width kana alphanumeric characters", "code", or the like is switched according to an input mode. When handling, the key input code is read as "Kana" or "Romaji" and is converted into a kanji depending on the conversion mode. The switching between the input mode and the conversion mode is executed in response to a mode switching instruction operation performed by the user using a keyboard, a mouse, or the like.
