Abstract

L'invention concerne un dispositif de conversion de caractère (1) comprenant unité de dictionnaire de caractères Kanji (41) contenant des informations de correspondance de caractère Kanji (144) incluant des caractères Kanji et leurs lectures associées aux caractères Kanji et des indices de caractère Kanji (145) dans lesquels les premiers caractères de pin-ins sont associés à des informations d'adresse sur les emplacements de stockage des caractères Kanji dont les premières parties sont les premiers caractères dans les informations correspondant au caractère Kanji (144), une unité de dictionnaire de mots (42) contenant des informations de correspondance de mot (162) incluant des mots et leurs lectures associées aux mots et des indices de mot (161) dans lesquels les premiers caractères des mots sont associés aux informations d'adresse sur les emplacements de stockage des mots dont les premières parties sont les premiers caractères dans les informations de correspondance de mot (162), et des moyens d'acquisition de mots qui font référence à l'unité de dictionnaire de caractères Kanji (41) et à l'unité de dictionnaire de mots (42) selon le premier caractère du premier pin-in d'une chaîne de caractères d'entrée et acquiert un mot correspondant à la chaîne de caractères d'entrée. Le délai mis pour rechercher un mot correspondant à la lecture d'entrée peut être raccourci.
