ABSTRACT:
A remote call registration system for an elevator including a transmitting device carried by a user and a receiving device disposed at a position near to but spaced a distance from the elevator hall. A signal transmitted from the transmitting device is received by the receiving device when the user is at a given walking distance from the elevator hall and sent to a call registration device to register the call prior to arrival of the user at the elevator hall. The distance between the receiving device and the elevator hall is predetermined to be substantially equal to the walking distance corresponding to a mean waiting time required for the cage to arrive at the hall after the call is registered by the call registration device. Thus, the user's waiting time at the elevator hall is substantially reduced.
