PROBLEM TO BE SOLVED: To surely prevent a collision of cars while preventing the lowering of service performance by a simple constitution.SOLUTION: A region which has a distance at which a second car 4 can be stopped in response to an absolute speed of the second car 4 on the occurrence of an abnormality, and does not permit the intrusion of a first car 2 is set as an exclusive region 302B of the second car. An absolute position which is advanced to a direction of a first car 2 by a distance not shorter than the exclusive region 302B is set as a stop limit position 301A of the first car 2 from an absolute position of a tip of the second car 4 in a direction of the first car 1. A plurality of thresholds for detecting the approach of the abnormality stepwise are set so that the first car 2 can be decelerated in speed and stopped before the stop limit position 301A of the first car 2.SELECTED DRAWING: Figure 1

    【課題】本発明は、簡単な構成により、サービス性の低下を防止しつつ、かご同士の衝突をより確実に防止することを目的とするものである。【解決手段】異常に対し、第2のかご4の絶対速度に対応して第2のかご4を停止させることができる距離であり、第1のかご2の進入を許さない領域が第2のかごの排他領域302Bとして設定されている。第2のかご4の第1のかご1方向の先端の絶対位置から、排他領域302B以上の距離を第1のかご2方向に進めた絶対位置が、第1のかご2の停止限界位置301Aとして設定されている。第1のかご2の停止限界位置301Aまでに第1のかご2が減速し停止できるように、異常接近を段階的に検出する複数の閾値が設定されている。【選択図】図1
