ABSTRACT:
An elevator car call selection apparatus is disclosed in which in order for at least a car covering a plurality of floors to serve at least a hall call or cage call, an advance position where said car in travel is capable of stopping by deceleration and the presence or absence of the call at an advance floor corresponding to the advance position are detected, so that the floor to be next served by the car is decided in response to a call generated at the advance floor. In order to calculate the advance floor with an electronic circuit and detect a call to be next served according to the result of the calculation, the apparatus comprises means preset to produce step signals at time points when the advance floor is advanced progressively after the starting of the car. The signal representing the car-starting floor and the step signal are used to calculate the advance floor progressively advanced after the starting of the car, so that when a call is generated for a floor corresponding to the advance floor, that particular floor is determined as a floor to be next served by the car.
