Abstract
Abstract A floor call registering circuit for an elevator system includes a keyboard at each floor for inputting the destination floors. The call registering circuit at the main stopping location permits only travels to destination floors which are allocated to a certain group of destination floors. According to an alternate embodiment, the call registering circuit is provided either with a pulse generator or with a decade keyboard. If the keyboard at the main stopping location has keys for all the destination floors, a circuit is provided which frees the destination floor calls allocated to the certain group of destination floors and blocks the destination floor calls lying outside the certain group of destination floors.
