ABSTRACT:
An apparatus for selecting a storey call at a transportation installation, especially an elevator system, which contains storey call storages and a scanning device which continuously scans the storey call storages and produces a signal sequence containing the stored storey calls, as well as possessing a selector which signals the location of the elevator cabin. Upon coincidence of the elevator cabin location and the scanner position there is produced a coincidence signal which, in conjunction with an information signal signalling the operating state of the elevator cabin, is delivered to a selector circuit. Both signals act by means of a first NOR-gate and a storage upon a second NOR-gate of the selector circuit. Storey call signals which have been selected from the signal sequence produced by the scanner device and ordered in accordance with the time sequence of their input are delivered to a further input of the second NOR-gate. If there simultaneously appear the information signal signalling the travel readiness of the elevator cabin and the coincidence signal, then at the output of the second NOR-gate there appears a control signal which, in the direction of travel of the scanner device, corresponds to the storey call situated closest to the coincidence signal.
