Claims (3)
- 生体内撮影用の撮像装置と、処置具を体腔内に挿入するための鉗子チャンネルとが挿入部に配設された電子内視鏡において、
前記撮像装置は、電子内視鏡の先端部に配置され、生体内の観察部位の像光を取り込むための対物光学系と、
この対物光学系の光軸に撮像面が平行となるように配置されて、プリズムにより前記像光が前記撮像面に導光され、前記撮像面上に空隙を空けてカバーガラスが取り付けられるとともに、前記撮像面が設けられた表面の、前記挿入部後端側の辺縁部に、信号端子が集中配置された撮像素子のベアチップと、
前記ベアチップに取り付けられ、前記ベアチップと略同等の厚さをもち、前記挿入部先端側の辺縁部に、前記ベアチップの信号端子にワイヤボンディングにより接続される信号端子が集中配置された回路基板と、
前記ベアチップよりも狭い横幅を有し、前記ベアチップの裏面から前記回路基板の裏面に渡って、その片側に寄せて配置され、前記ベアチップと前記回路基板とを電気的に接続する導電板とを備え、
前記鉗子チャンネルは、前記導電板によって前記ベアチップおよび前記回路基板の裏面に形成された切欠き部に、その外周の一部が入り込むように配置されたことを特徴とする電子内視鏡。 - 前記ベアチップの後端面に前記回路基板を接着し、これらの接着部分をまたぐように前記導電板を取り付けたことを特徴とする請求項1に記載の電子内視鏡。
- 前記導電板を介して、前記撮像素子に電子シャッタの駆動制御信号が入力されることを特徴とする請求項1または2に記載の電子内視鏡。
