Abstract

L'invention concerne un appareil d'écriture électronique (2) muni d'une partie de montage (24) pour le montage d'un support papier (70). Lors de l'opération d'écriture, une zone de pression, où se trouve le papier (70) qui reçoit la pression d'un crayon, est détectée, de même que la force de pression dans la zone de pression. Il est déterminé si l'ampleur de la force de pression dans la zone de pression détectée est égale ou supérieure à un seuil spécifié prédéterminé. La relation de position relative parmi les zones multiples de pression est détectée quand les zones multiples de pression sont détectées en même temps. Quand des zones multiples de pression sont détectées, une zone où le crayon appuie (3) est identifiée parmi les zones multiples de pression en conformité avec les résultats de détermination de pression et les résultats de la détection de position relative, et des données de trait correspondant à l'enregistrement sur le support papier (70) sont générées en utilisant les informations de position de la zone de pression ainsi identifiée.
