Abstract
A landing control system comprising an elongated nonmagnetic strip extending vertically along the length of the shaft, having along its length, at predetermined sites, magnetic adhesive tape containing coded information. A sensor for reading the coded information is mounted on the exterior of the elevator car grasping the nonmagnetic strip by a pair of tape guides, the guides being spaced as to permit the centrally located magnetic adhesive tape to pass freely into the sensing area without, while avoiding contact with the tape.
