PROBLEM TO BE SOLVED: To provide an endoscope having a function of detecting an abnormality in transmission of drive force between a pulling member and a drive section, and controlling to stop the driving when the abnormality is detected.SOLUTION: An endoscope has: an inserting section 2 having a bending section 2b a pulling member 8 for bending the bending section an operation member 5 for inputting force magnitude required to pull the pulling member a drive section 12 for generating a drive force to bend the bending section by pulling the pulling member a pulling member installed section 9 capable of being switched from a state where the drive force is not transmitted to the pulling member to a state where the drive member is transmitted to the pulling member, interlockingly with the pulling operation of the pulling member a detecting section 15b for acquiring the drive force transmission state transmitted from the drive section to the pulling member installed section, as drive force transmission state information and a control section 15 for determining whether the drive force transmission state is abnormal or not by using the drive force transmission state information acquired by the detecting section, and if the abnormality is detected, outputting a control signal for stopping the drive section to the drive section.COPYRIGHT: (C)2013,JPO&INPIT【課題】牽引部材と駆動部との間に生じる駆動力伝達異常を検出し、異常検出時に駆動停止制御する機能を備えた内視鏡を提供する。【解決手段】湾曲部2bを有する挿入部2と、湾曲部を湾曲させる牽引部材8と、牽引部材を牽引するための力量を入力する操作部材5と、牽引部材を牽引して湾曲部を湾曲させる駆動力を発生させる駆動部12と、牽引部材の牽引動作に連動して牽引部材に対して駆動力が伝達しない状態から牽引部材に対して駆動力が伝達する状態に切り換え可能な牽引部材設置部9と、駆動部から牽引部材設置部に対して伝達される駆動力の伝達状態を駆動力伝達状態情報として取得する検出部15bと、検出部が取得した駆動力伝達状態情報を用いて駆動力の伝達状態が異常であるか否かを判断し、異常であることを確認した場合には、駆動部を停止させる制御信号を駆動部へ出力する制御部15とを有する。【選択図】図3
