Abstract

Une personne d'une taille prescrite à détecter se trouve dans une cage d'ascenseur ou dans une cabine, et un détecteur se trouve dans l'autre de ces lieux. Le détecteur comporte deux capteurs de position de palier qui sont disposés à un certain intervalle l'un de l'autre le long d'une direction de déplacement de la cabine et qui effectuent une opération de détection en faisant face à la personne à détecter, ainsi que deux capteurs de réglage de position d'étage et un capteur de position d'ouverture et de fermeture de porte. Le capteur de réglage de position d'étage est placé entre les capteurs de position de palier et le capteur de position d'ouverture et de fermeture de porte est placé entre les capteurs de réglage de position d'étage. Dans le détecteur, toute opération de détection de chaque capteur de position de palier cesse lorsque la position de la cabine dévie d'une zone de palier de cabine prescrite, toute opération de détection de chaque capteur de réglage de position d'étage cesse lorsque la position de la cabine dévie d'une zone qui permet le réglage d'étage et qui est adjacente à la zone de palier de cabine, et une opération de détection du capteur de position d'ouverture et de fermeture de porte cesse lorsque la position de la cabine dévie de la zone d'ouverture et de fermeture de porte comprenant la zone de palier de cabine et la zone permettant le réglage d'étage.
