In step 401, it is determined whether or not the elevator car 11 is stopped. If not stopped, the process proceeds to step 402, where the output signal to the external device operating device 19 is reset. On the other hand, if the car 11 has stopped, the process proceeds to step 403, and the presence or absence of a passenger in the car 11 is determined by the in-car load detection device 13.
If there is no passenger, the process proceeds to step 402 in the same manner as described above, and the output signal to the external device operating device 19 is reset. If there is a passenger, the process proceeds to step 404, where the position of the car 11 is detected by the position detecting device 9 of the car 11, and the car 1
It is detected whether or not the position 1 is a door openable position (door zone). If the door can be opened and closed, step 402 is the same as described above.
Then, the output signal to the external device operating device 19 is reset. On the other hand, if the door cannot be opened and closed, the process proceeds to step 405, where an output signal to the external device operating device 19 is set. As a result, the above-described safety operation is performed, and the current process ends in step 406.

In this embodiment, (1) that the car 11 with the passenger stops outside the door zone determines the confinement, but various modifications can be considered. For example, (2) there is a passenger in the car 11 and a predetermined time has elapsed with the door closed, (3) there is a passenger in the car 11 and a predetermined time has elapsed outside the door zone, or (4) the car It can be determined that the vehicle is confined, for example, when a predetermined long period of time has elapsed while there is a passenger inside the vehicle.

FIG. 5 shows a processing flowchart of the microcomputer in the external operation device 19. This process is also started by a periodic timer interrupt about once every 40 [ms]. In step 501, the presence or absence of a confinement detection signal is determined.
