<p>PROBLEM TO BE SOLVED: To provide an elevator stop position detection device capable of detecting a stop position of a car of an elevator safely with high precision.SOLUTION: An elevator stop position detection device includes a landing reference plate 6 installed on a wall side of a building and a position detection part 5 installed in a car 1 of an elevator. The landing reference plate 6 includes a detected resonance circuit including a detected coil 11. The position detection part 5 includes detection coils 13, 14 which are provided side by side along a moving direction of the car 1 and electromagnetically coupled to the detected coil 11, detection circuits 18, 19 which output a displacement direction and a displacement quantity of the car 1 on the basis of outputs of the detection coils 13, 14, a differential circuit 20, an adding circuit 21, a variable gain amplifying circuit 22, etc.</p> |
