In step S1, it is determined whether the optical axis 12 is blocked.
If not blocked, the process ends, and if blocked, the process proceeds to step S2. In step S2, it is determined whether the door is open. If the door is open, the door motor 14 is reversed in step S3 to move the car doors 7, 8 and the landing doors 3, 4 in the door closing direction. If the car room 5 is not running and the car room 5 is running, it is determined in step S4 whether the car room 5 has landed on the floor on which the call is registered. If not landed, step S1
Return to.

If it is the car room 5 side, in step S6, an alarm is issued by the alarm device in the car room 5 to warn the passengers that they will leave the car doors 7 and 8. On the side of the hall (corresponding to FIG. 4 or FIG. 5), in step S7, an alarm is issued by the alarm of the hall to warn the waiting passengers to leave the hall doors 3 and 4. Steps S6 and S7
After the execution, in step S8, it is judged again whether or not the optical axis 12 is blocked. If the blocking is continued, the procedure returns to step S5 to repeat the alarm, and if it is not blocked, the step S8 is repeated.
Open the door at 9.
