A call registering and indicating device includes a keyboard wherein calls for desired floors of destination can be entered without pressing a register key after a correct input or pressing a correction key after an incorrect call input. A call input is possible only if a proximity switch connected with the call input keyboard is activated. On deactivation of the proximity switch, a delay circuit causes the call to be automatically registered. An erroneously entered call is automatically cancelled by means of a second control circuit, where simultaneouly a second indicating element lights up in the form of a double question mark. A third indicating element, signaling the selected elevator, located on the same indicating panel, as well as a fourth and fifth indicating element, signaling the position of the selected elevator in relation to the actuated keyboard, are connected with a group control circuit by way of further control circuits. In response to the call assignment, the third and the fourth or fifth indicating elements are activated, which then will light up together with a first indicating element signaling the selected floor of destination at the input of the call.
