にかかるという問題もあった。When the car 2 is stopped and the car 2 is stopped between the floors and the passenger is trapped during the running of the car 2, the terminal device 9 sets the operating state of the car 2. Although the monitoring center 8 is notified of the abnormality, the terminal device 9 does not report the state of the car 2 thereafter. Therefore, in order to check whether the car 2 has actually landed on the nearest floor and the passenger rescue operation has been completed under the control of the control unit 32, the monitoring center 8 must always dispatch a maintenance technician to the site. However, there is also a problem that the operation cost is significantly increased.

構成が簡単なもので済む。Since the present invention is constructed as described above, when the car is running and the normal power supply is in a power outage state and the car stops between floors and a confinement accident occurs, the control device transmits the terminal device to the terminal device. In response to these abnormality detection signals, the terminal device informs the monitoring center of an abnormality in the operating state of the car via a communication line in response to the abnormality detection signals. In addition, since the abnormality detection signal is transferred from the terminal device to the landing controller by the signal transfer means, the landing controller automatically causes the car to land on the nearest floor. This eliminates the need for two communication lines and two input sections to process the abnormality detection signal output from the control device, so that the configuration for processing the abnormality detection signal can be simplified.
