Abstract: A safety check system of the invention is equipped with a safety detection device attached to a body of a checked person, a server for accumulating various pieces of information, and a terminal of a checker for executing a safety check of the checked person, wherein the detection device is equipped with a first radio communication mechanism for making a radio communication with the server, a vital signal detection mechanism for detecting a vital signal of the checked person, and a first control mechanism for creating safety information of the checked person; and the server is equipped with a second radio communication mechanism for making a radio communication with the detection device, a detection history memory mechanism for memorizing a detection history of the checked person, and a second control mechanism for sending the detection history of the checked person in the detection history memory mechanism to the terminal.

Abstract: An elevator is capable of transmitting signals between an elevator control unit and a car control unit without using tail cords. Resin-coated ropes for suspending an elevator car and a counterweight comprise conductive metal wires. Transmitter-receivers use the conductive metal wires of the ropes for contactless signal transmission. The conductive metal wires of the two ropes are connected in rope-anchoring parts to form an electrical closed loop for signal transmission.
