[origin: EP1876134A2] At the present invention a multi-car elevator includes: an in-tower transmitter (5b) which generates a sound signal, the in-tower transmitter (5b) being provided on a measuring side of a first sound signal conductor (4a); an in-tower detector (6b) which detects the sound signal, the in-tower detector (6b) being provided on the measuring side of a second sound signal conductor (4b); on-car detectors (7a) provided on respective cars (1); and on-car transmitters (8a) provided on respective cars (1). The in-tower transmitter (5a) generates a call signal, the on-car transmitters (8a) generate the response signals to the second sound signal conductor (4b) after the call signal is detected by the on-car detectors to obtain positions of the respective cars (1).
