PROBLEM TO BE SOLVED: To provide a capsule-type endoscope including both of a power receiving coil and a magnet for induction operation and capable of appropriately performing power supply and induction.SOLUTION: A capsule-type endoscope 20 according to the present invention includes a power receiving coil 21 for non-contact power supply, and a magnet 22. The power receiving coil 21 of the capsule-type endoscope 20 is so provided that coils are wound around an external surface of a core composed of a magnetic substance, in triaxial directions orthogonally crossing with one another. The power receiving coil 21 and the magnet 22 are spaced from each other, and a circuit board is installed in a clearance formed between the power receiving coil 21 and the magnet 22. The capsule-type endoscope 20 is so configured that a power feed coil 12 supplies the power receiving 21 with the electric power by magnetic resonance coupling system, and is inducedly operated by magnetic force applied to the magnet 22 by an induction coil 14.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】受電コイルと誘導動作用の磁石の双方を備え、的確に給電と誘導ができるカプセル型内視鏡とカプセル型内視鏡の駆動システムを提供する。【解決手段】本発明に係るカプセル型内視鏡20は、非接触給電用の受電コイル21と磁石22とを内蔵したカプセル型内視鏡20であって、受電コイル21は、磁性体からなるコアの外面に、相互に直交する3軸方向にそれぞれコイルが巻回して設けられ、受電コイル21と磁石22とが相互に離間して設けられ、受電コイル21と磁石22とが離間する空隙内に、回路基板が設置されている。カプセル型内視鏡20は、給電コイル12により磁界共振結合方式により受電コイル21に給電され、誘導コイル14により磁石22に作用する磁力により誘導動作される。【選択図】図2
