PURPOSE:To carry out a back-up operation with high efficiency by making an operation control portion selectively carry out the automatic operation of each-floor stopping and skipping with respect to unservable floors in accordance with the output of an unservable floor detecting portion at the time of detecting the abnormality of a riding place call registration. CONSTITUTION:A cage call registration signal 1 is inputted into a cage call registering portion 2 and the registered result is inputted into the operation control portion 6 of an elevator. Also, a signal 7 indicating the condition of a riding place call registration system is inputted into a riding place call registration abnormality judging portion 8 to judge the normalcy/abnormality thereof and the result is inputted into the control portion 6. An unservable floor detecting portion 5 always detects and outputs unserving floors and, once the whole floor service is over, the whole floors are again outputted as unservable. When abnormality of riding place call registration is detected, the control portion 6 selectively carries out the automatic operation of each-floor stoppage or skipping with respect the unservable floors in accordance with the output of the detecting portion 5. Thereby, a cage call preference operation can be carried out while balancedly serving for each floor, enabling service with high efficiency. |
