PURPOSE:To cut the equipment cost by installing an antenna which receives and transmits electric waves into a nonmetallic body on a door on an elevator boarding place side or a door on a cage side. CONSTITUTION:The glass surface of the glass window 22 of a boarding place door 21 is printed into square loop form by the electric conductive paint, and one side is cut to form a terminal, and an antenna element 23 is formed, and a lead wire 24 is led to a connector 25 from the terminal, and further connected to a radio receiver/transmitter on an elevator controller side through an outside feeder 26. In this case, electric waves can be transmitted and received without influence on the environmental materials. When a certain data is transmitted from a submachine 10, and antenna 23A (e.g., 23A on the first floor) installed on the boarding place side receives the data, which is led to a radio receiver/ transmitter (host machine) 20 on the elevator controller 30 side through the outside feeder 26A, and the data is treated, and the signal is a received and transmitted between the controller 30. Therefore, calling for elevator and recognition of passengers, etc., can be carried out. |
