Abstract

La présente invention concerne un dispositif de production de signal de suivi de position et un système de saisie comprenant un appareil de saisie de suivi de position assurant la saisie d'informations en effectuant le suivi de la position de l'appareil de production de signal de suivi de position. L'appareil de production de signal de suivi de position est capable de saisir avec précision des informations relatives au suivi de position en émettant un signal d'onde ultrasonique sur une trajectoire de guidage formée entre une partie de guidage et une unité de production de signal d'onde ultrasonique dans une seule direction de la surface de papier indépendamment de la manière dont l'utilisateur se sert de l'appareil de production de signal de suivi de position. En outre, dans l'appareil de production de signal de suivi de position, l'unité de production de signal d'onde ultrasonique comprend une pluralité d'éléments de production d'ondes ultrasoniques qui produisent séquentiellement des ondes ultrasoniques à un intervalle de temps prédéterminé calculé en fonction des distances de séparation entre les éléments de production d'ondes ultrasoniques de sorte que le signal d'onde ultrasonique peut être amplifié par superposition des ondes ultrasoniques produites par les éléments de production d'ondes ultrasoniques. Ainsi, l'appareil de production de signal de suivi de position peut également transmettre de manière stable le signal d'onde ultrasonique à un détecteur de réception de signal d'onde ultrasonique qui se trouve à une distance éloignée.
