PROBLEM TO BE SOLVED: To provide a noncontact power feeder system capable of suppressing the influence of disturbance light and accurately detecting the positional relation between a transmission coil and a reception coil.SOLUTION: Light-emitting elements 14a to 14d blink on and off each in a predetermined emission cycle, for predetermined emission time, at predetermined emission intensity. The emission cycle of each of the light-emitting elements 14a to 14d decreases from T1 to T2 and to T3 as a distance between a transmission coil 1 and a reception coil 12 is shorter. The emission intensity decreases from I1 to I2 and to I3 as the distance between the transmission coil 11 and the reception coil 12 is shorter. The emission time is, however, constant to t0. An imaging cycle of a camera 15 is synchronized with the emission cycle to decrease from T1 to T2 and to T3 as the distance between the transmission coil 11 and the reception coil 12 is shorter. Furthermore, exposure time is identical to the emission time and t0. The camera 15 images the light-emitting elements 14a to 14d for the exposure time identical to the emission time in the imaging cycle synchronous with the emission cycle.

    【課題】外乱光の影響を抑え、送電用コイルと受電用コイルの位置関係を精度よく検出することができる非接触給電装置を提供する。【解決手段】発光体14a〜14dは、決められた発光周期、発光時間及び発光強度で点滅する。発光体14a〜14dの発光周期は、送電用コイル11と受電用コイル12の距離が小さくなるに従って、T1からT2、T3へと小さくなる。発光強度は、送電用コイル11と受電用コイル12の距離が小さくなるに従って、I1からI2、I3へと小さくなる。しかし、発光時間はt0で一定である。カメラ15の撮像周期は、発光周期に同期し、送電用コイル11と受電用コイル12の距離が小さくなるに従って、T1からT2、T3へと小さくなる。また、露光時間は発光時間と同一のt0になる。カメラ15は、発光周期に同期し、発光時間と同一の露光時間で発光体14a〜14dを撮像する。【選択図】図11
