In an elevator apparatus, a guide rail has a plurality of unit rails that are vertically connected to each other. A car is provided with a rail joint detecting device mounted on the car, for detecting the presence/absence of a joint between each of the unit rails. The rail joint detecting device has a joint detecting portion for optically detecting the presence of the joint; and a joint determining portion for determining the presence/absence of the joint based on information from the joint detecting portion. Information on the presence/absence of the joint is outputted from the joint determining portion to a car position correcting circuit. In the car position correcting circuit, information on the position of the car is corrected based on the information on the presence/absence of the joint.
Un système ascenseur dans lequel un rail guide présente une pluralité de rails unitaires couplés verticalement. La cabine présente un détecteur de joint rail permettant de détecter le joint dans les rails unitaires. Le détecteur présente une section de détection de joint optique et une section de jugement du joint permettant de savoir si un joint est présent d'après l'information reçue depuis la section de détection de joint. L'information permettant de savoir si un joint est présent est acheminée depuis la section de jugement de joint vers un circuit de correction de la position de la cabine où l'information sur la position est corrigée d'après l'information sur la présence d'un joint.
