PROBLEM TO BE SOLVED: To provide an elevator operating device capable of efficiently extracting long periodical vibration among the vibration caused by an earthquake to use it for emergency operation control. SOLUTION: A band path filter circuit 17 extracts a long periodical vibration component on the basis of a difference between a real speed value, which is computed by a real speed computing circuit 12 on the basis of a pulse signal from a pulse generator for generating pulse signal in proportion to travelling distance of an elevator car, and a speed command value from a speed pattern command generating circuit 11. When the extracted vibration component is the predetermined value or more and continued for the predetermined time or more, occurrence of earthquake is determined for emergency operation control of the elevator.
