ABSTRACT:
An elevator car position detecting apparatus includes plates arranged at selected operation points defined along the elevator path, in such arrangement that one operation point is distinguishable from another operation point. Position detectors are provided on a car so that as car moves past the operation points the position detectors communicate with corresponding plates without contacting the plates. The position detectors associated with the corresponding plates generate signals indicating that the elevator car has reached the corresponding position.
