摘要:
To alleviate the ear block discomfort of passengers without causing any undue reduction in the operational efficiency of an elevator. A travel distance calculating section 13 calculates a travel distance of a car room 1 based on destination floor information 12a and a car position command signal 3a, and output travel distance information 13a to a speed pattern generating section 14. The speed pattern generating section 14 compares the travel distance with a predetermined distance, generates a speed pattern 14a of a normal operation if the travel distance is short, and generates the speed pattern 14a of a partially low speed operation if the travel distance is long. The predetermined distance indicates a difference in height corresponding to a difference in air pressure that causes the Eustachian tube to open against ear block discomfort by a passenger. A speed control section 24 makes the car room 1 move up and down based on the speed pattern 14a. This allows the car room 1 to move at low speed after the first opening of the Eustachian tube, and therefore an interval in time when the car room 1 moves of a distance of the difference in height causing another ear block discomfort is made long. The ear block discomfort of passengers may thus be alleviated.
