Abstract
An indicating device for which the passengers waiting at a floor can recognize immediately whether the calls entered by them at the floor for desired destination floors have been assigned to an arriving car so that rapid entry decisions can be taken. To this purpose, the indicating device includes a first and a second indicator element in the form of an upward and a downward arrow, and a third indicator element signaling an entry prohibition. A floor circuit connected with the indicator by way of three inputs activates through the first and second inputs, the first and the second indicator elements respectively, if the entered calls are assigned to the arriving car, and by way of the third input activates the third indicator element, if the entered calls have not been assigned to a car arriving at a floor.
