PROBLEM TO BE SOLVED: To provide a pulling-in prevention device for an entrance at the landing of an elevator having less number of wirings in a sucking detection device at a landing on each story and capable of preventing passengers from being pulled-in by a simple structure.;SOLUTION: Operating outputs from detection devices 1 at those landings excluding the landings where a car is stopped by a detection control device 15 are eliminated through detection output mask signals. By this, when the detection device 1 is operated when a pulling door on the landing where the car is stopped is opened, the pulling door opened through a door opening/closing device 14 is controlled for abnormality by the detection control device 15. In this structure, the number of wirings is reduced by connecting, in series, the detected devices 1 installed on the plurality of landings through detection wirings 12. The cost for manufacture, installation, and maintenance can be saved by reducing the number of wirings of the detection device 1.;COPYRIGHT: (C)2005,JPO&NCIPI
