摘要：
PROBLEM TO BE SOLVED: To provide an endoscope capable of changing the viewing field direction during imaging in a wider range without causing an increase in apparatus size while also being capable of being assembled easily with a simple configuration that connects driving rods via connecting members to an advancing and retracting driving device and being capable of reliable drive transmission.SOLUTION: The endoscope is provided with: an imaging holder that holds an imaging unit driving force transmission mechanisms that each comprises a pair of driving rods 22, 23, wherein the leading ends are connected at mutually diagonal positions on the imaging holder a driving device that advances and retracts the driving rods 22 a support shaft extended from the base member side of the driving device a relaying holder 42 that is furnished on the support shaft and supports the intermediate portions of the driving rods and a cover member that covers at least a portion thereof, and is configured to connect the base end of one driving rod 22 of each driving force transmission mechanism to the driving device via a connector 78.COPYRIGHT: (C)2012,JPO&INPIT【課題】装置の大型化を招くことなく撮像時における視野方向の変更をより広い範囲で実施できると共に、連結部材を介して駆動用ロッドを進退駆動する駆動装置に連結させる簡単な構成で容易に組み立てることができるとともに、駆動伝達を確実に行なうことができる内視鏡を提供することを目的とする。【解決手段】本発明の内視鏡は、撮像ユニットを保持する撮像用ホルダと、撮像用ホルダに対して先端側が互いに対角位置に連結された一対の駆動用ロッド22、23をそれぞれ含む駆動力伝達機構と、駆動用ロッド22を進退駆動する駆動装置と、駆動装置のベース部材側から延設された支持シャフトと、支持シャフトに取り付けられ、駆動用ロッドの中間部を支持する中継用ホルダ42と、それらの少なくとも一部を覆うカバー部材とを備え、連結器78を介して各駆動力伝達機構における一方の駆動用ロッド22の基端部を駆動装置に連結する構成とする。【選択図】図9
