PURPOSE: A noncontact power-feeding device is provided to supply electric power to a mobile apparatus on the non-contact basis, transfer signals on non-contact basis, reduce the size thereof and also assure safe and stable operation. CONSTITUTION: A power line(3), which supplies an AC current, is installed along the moving route of the mobile apparatus(10) and an electric power receiving part(1), including a pickup(12) provided adjacent to the power feeding line(3) is also provided to the mobile apparatus(10) for supplying the electrical power thereto. Moreover, a fixed apparatus(2) for optical communication fixed for the power feed line(3) and a mobile apparatus(11) for optical communication provided to the electric power receiving part(1) are also provided. Optical communication is realized with the optical path, provided along the power feed line(3) and signals are transferred to the mobile apparatus(10). The apparatus is reduced in size. A cover(4) made of conductive material which surrounds the power feeding line(3) is also provided to confine electromagnetic waves generated from the power feed line(3). 본 발명은 비접촉급전장치에 관한 것으로, 이동체에 전력을 비접촉으로 공급함과 동시에 신호를 비접촉으로 전송하고 또 장치를 소형화하는 것이 가능해지며 더욱이 안전하고 안정적으로 운용할 수 있는 비접촉급전장치를 제공한다. 본 발명에서는, 이동체(10)의 이동경로를 따라 교류전류가 흐르는 급전선(3)을 설치하고 급전선(3)에 근접시킨 픽업(12)을 갖는 수(受)전선(1)을 이동체(10)에 구비하여 전력을 공급한다. 또, 급전선(3)에 대해 고정된 광통신고정기(2)와 수전부(1)에 설치한 광통신이동기(11)를 구비하며 급전선(3)에 따라 조성되어 있는 광로에서 광통신을 행하여 이동체(10)로 신호를 전송하는 방법으로 장치가 소형화된다. 더욱이 급전선(3)을 둘러싸는 도전재제의 커버(4)를 구비하고 급전선(3)이 발생하는 전자파를 봉쇄한다. 이에 의해 광통신에 의한 신호전송이 안정되고 또 외부 기기에 대한 전자적인 영향을 방지하여 안전성을 높이는 기술을 제시한다.
