PROBLEM TO BE SOLVED: To provide a position detection system of an elevator capable of upgrading precision in detecting the position of a car without making the structure complex, and an elevator including the position detection system.SOLUTION: The present invention is a position detection system 12 of an elevator 1 that is disposed in the elevator 1 which ascends or descends in a hoistway 2 of a building and includes a car 4 that moves to a landing 3 on each floor, and that detects the position of the car 4. The position detection system 12 includes a permanent magnet 150 that is disposed on each of the landings 3 and magnetized, a coil 160 that is disposed in the car 4 in the form of a closed circuit, and interlinks with a flux of a magnetic field, which is formed by the permanent magnet 150, when the car 4 approaches the landing 3, a property detector 17 that detects as an analog signal a predetermined property which is susceptible to a change in the magnetic flux of the permanent magnet 150 interlinking with the coil 160, and a position identifier 18 that identifies the position of the car 4 on the basis of the analog signal detected by the property detector 17.SELECTED DRAWING: Figure 3

    【課題】構造が複雑化することなく、乗りかごの位置の検出精度を向上させることができるエレベーターの位置検出装置、及びこの位置検出装置を備えたエレベーターの提供。【解決手段】本発明は、建物の昇降路2内を昇降し、各階の乗り場3へ移動する乗りかご4を備えたエレベーター1に設けられ、乗りかご4の位置を検出するエレベーター1の位置検出装置12において、乗り場3に設けられ、帯磁した永久磁石150と、乗りかご4に閉回路状に設けられ、乗りかご4が乗り場3に接近した際に、永久磁石150によって形成された磁界の磁束と鎖交するコイル160と、コイル160に鎖交する永久磁石150の磁束の変化により影響する所定の特性をアナログ信号として検出する特性検出部17と、特性検出部17によって検出されたアナログ信号に基づいて、乗りかご4の位置を特定する位置特定部18とを備えた。【選択図】図3
