PROBLEM TO BE SOLVED: To provide an endoscope that prevents damage at a light emission surface of a light source when it is not used and acquires high transfer efficiency of light when it is used.SOLUTION: An endoscope 1 includes: a light source 2 having a light emission surface 2a for emitting light a light guide 3 for guiding incident light at a first end surface 3a to emit light from a second end surface 3b and a contact control mechanism 4 for changing the light emission surface 2a and the first end surface 3a from an alienation state to a contact state in response to a trigger on action interlocking with use of the light guide 3.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】未使用時の光源の発光面の損傷を防ぎ、使用時に光の高い伝達効率を得ることができる内視鏡を提供する。【解決手段】光を射出する発光面2aを有する光源2と、第1端面3aに入射された光を導光し第2端面3bから出射するライトガイド3と、ライトガイド3の使用に対応付けられたトリガオンアクションに応じて、発光面2aと第1端面3aを離間状態から接触状態に変化させる接触制御機構4と、を備える内視鏡1。【選択図】図1
