| description | To achieve the high accuracy of detection of a foreign object and a reduction in the area of a substrate.SOLUTION: A foreign object detection device 20 includes: a detection coil unit 22 including a detection coil substrate 220 and a plurality of coils 242 which are formed on one surface of the detection coil substrate 220 and each include a conductive pattern turned around the Z axis; and a detector 26 connected to the coils 242 to detect the existence of a foreign object based on a vibration signal output when each of the coils 242 is excited. The coils 242 each have an opening. The detection coil substrate 220 has a through hole 228 extending through the detection coil substrate 220, and a component space where a component 248 or a wire 250 is arranged, within each of the openings as seen in the Z-axis direction.SELECTED DRAWING: Figure 4
【課題】異物検出精度を高くかつ基板面積を小型化可能とすることを目的とする。【解決手段】異物検出装置２０は、検出コイル基板２２０と、検出コイル基板２２０の一面に形成され、Ｚ軸を中心に周回する導体パターンを有する複数のコイル２４２と、を備える検出コイルユニット２２、複数のコイル２４２に接続され、各コイル２４２が励磁されたときの振動信号から、異物の有無を検出する検出部２６と、を備える。複数のコイル２４２は、それぞれ開口部を有し、検出コイル基板２２０は、Ｚ軸方向に見て、開口部内に、検出コイル基板２２０を貫通する貫通穴２２８と、部品２４８または配線２５０が配設された配置スペースと、を有する。【選択図】図４ |
