PURPOSE: To simplify a transmitting means and increase reliability by providing a load-carrying platform with a receiving part, positioned near to a transmitting part on the objective floor side to uncontactedly receive output from the transmitting part when the load-carrying platform passes respective objective floors.
CONSTITUTION: A transmission function for detected information is assumed to a load-carrying plarform 2, and output from a transmitting part 29 (TP), changed in accordance with the detected information by a detecting means 27 provided on the objective floor, is imparted to a receiving part 30 (RP) provided on the plarform 2 when the platform 2 passes respective objective floors following the elevating of the platform 2, after that, is outputted to an information input part 31 (IP) to a lift movement control device. Since the output is inputted into the lift movement control device via a cable 32, the installation of a cable from the control device to the detecting means 27 in the respective objective floors is eliminated. Moreover the information, from the transmitting part 29 in the respective objective floors to the receiving part 30 of the platform 2, is uncontactedly transmitted via a medium e.g. such as light or an ultrasonic wave, thereby eliminating conventional disconnection and a problem such as contact failure.
