Abstract
An elevator control system using an electric type floor selector is disclosed including a unit provided at at least one of the specific floors in the hoistway and for indicating the specific floor, units provided at the other floors than the specific floors and for indicating merely the floor, a detector provided at a car in which presence of both the units is detected and when the detector levels with the respective units the detector generates a signal corresponding to it, a floor indicator for indicating the floor at which the car actually stops by using the detected signal, and a stop permissible floor indicator for indicating the electrically calculated stop floor when the car stops. Comparison is made of the output of the floor indicator with the output of the stop permissible floor indicator. In the comparison, when these outputs are different, the car is moved to the specific floor. When the car stops at the specific floor, the floor indicator and the stop permissible floor indicator are set to the specific floor.
