以下、図1~図5を用いて、本発明の第1の実施の形態の制御信号送信装置である磁界発生装置20について説明する。図1に示すように本実施の形態の生体観察システムは、カプセル型内視鏡10と磁界発生装置20とを具備する。カプセル型内視鏡10は、磁界発生装置20の筐体25に配設された配置部である収納部21に収納可能である。そして、カプセル型内視鏡10は被検者の内部である消化器管腔に導入可能な生体情報取得装置であり、被検者が嚥下する直前に磁界発生装置20からの電磁界による制御信号を受信すると起動する。収納部21は筐体25に配設された凹部、言い換えれば内部に空間を有する壁部である。磁界発生装置20では、カプセル型内視鏡10は長軸方向を鉛直方向として収納部21に収納される。なお、以下、電磁界を磁界または電磁波ともいう。
以下、図6~図10を用いて本発明の第1の実施の形態の変形例の磁界発生装置20A~20Eについて説明する。本変形例の磁界発生装置20A~20Eは、第1の実施の形態の磁界発生装置20と類似しているため同じ機能の構成要素には同じ符号を付し説明は省略する。
次に、図11を用いて本発明の第2の実施の形態の磁界発生装置20Fについて説明する。本実施の形態の磁界発生装置20Fは、第1の実施の形態の磁界発生装置20と類似しているため同じ機能の構成要素には同じ符号を付し説明は省略する。
次に、図12を用いて本発明の第3の実施の形態の磁界発生装置20Gについて説明する。本実施の形態の磁界発生装置20Gは、第1の実施の形態の磁界発生装置20と類似しているため同じ機能の構成要素には同じ符号を付し説明は省略する。
次に、図13、図14を用いて本発明の第4の実施の形態の磁界発生装置20Hについて説明する。本実施の形態の磁界発生装置20Hは、第1の実施の形態の磁界発生装置20と類似しているため同じ機能の構成要素には同じ符号を付し説明は省略する。
次に、図15、図16を用いて本発明の第4の実施の形態の変形例の磁界発生装置20Jについて説明する。本変形例の磁界発生装置20Jは、第4の実施の形態の磁界発生装置20Hと類似しているため同じ機能の構成要素には同じ符号を付し説明は省略する。
次に、図17を用いて本発明の第5の実施の形態の磁界発生装置20Kについて説明する。本実施の形態の磁界発生装置20Kは、第4の実施の形態の磁界発生装置20Hと類似しているため同じ機能の構成要素には同じ符号を付し説明は省略する。
次に、図18を用いて本発明の第6の実施の形態の磁界発生装置20Lについて説明する。本実施の形態の磁界発生装置20Lは、第4の実施の形態の磁界発生装置20Hと類似しているため同じ機能の構成要素には同じ符号を付し説明は省略する。
