PROBLEM TO BE SOLVED: To improve detecting technique of a loading point in a hoistway of an elevator. SOLUTION: A floor alignment decision device for an elevator car relating to a loading point of a hoistway has a transceiver 26 transmitting a detection signal, a first reflector 28 changing a reflectance between maximum/minimum reflection ends, a second reflector 30 changing a reflectance between the maximum/minimum reflection ends, and a processor 32. The first reflector transmits a first reflection signal in response to the detection signal fed from the transceiver, the second reflector transmits a second reflection signal in response to the detection signal fed from the transceiver. The processor, in response to the first/second signal, decides whether the elevator cage is floor- aligned or not relating to the loading point. |
