PROBLEM TO BE SOLVED: To provide a support device which facilitates magnifying observation of a desired region.SOLUTION: A support device 1 supports an endoscope 100 comprising: an insertion part 110 which is formed in a rod shape extending in an axis CL direction, has one end which can be inserted into a body, and transmits information on an image inside the body from one end to the other end a connection part 130 which is provided at the other end of the insertion part 110 and used for connection with another device and a light guide part 120 for introducing light emitted from one end of the insertion part 110 from an external light source to the insertion part 110. The support device has body parts 10, 20, and a holding part 30 which extends from the body parts 10, 20 in a direction crossing the axis CL direction and holds at least a part between a position where the light guide part 120 introduces light into the insertion part 110 and the end of the connection part 130 which is on the opposite side to the insertion part 110.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】所望領域を拡大観察しやすい支持装置を提供することを目的とする。【解決手段】軸線CL方向に延びる棒状に形成され、一方の端部が体内に挿入可能とされ、体内の画像に関する情報を一方の端部から他方の端部に伝達する挿入部110と、挿入部110の他方の端部に設けられ、他の機器との接続に用いられる接続部130と、挿入部110の一方の端部から照射される光を外部光源から挿入部110に導入する導光部120と、を有する内視鏡を支持する支持装置100であって、本体部10,20と、本体部10,20から軸線CL方向と交差する方向に延びるとともに、導光部120が光を挿入部110に導入する位置から、接続部130の挿入部110と反対側の端部までの間の少なくとも一部を保持する保持部30を有することを特徴とする。【選択図】 図1
