Zusammenfassung:To provide a microscope capable of observing even a body part that cannot be observed by being shielded by a surgical instrument.SOLUTION: A microscope 3 includes a first observation optical system 4 for observing a subject S and a second observation optical system 5 whose direction to observe the subject S by the first observation system 4 is different and which shares an imaging part 42 of the first observation optical system 4. The second observation optical system 5 includes optical path changing means for converting the direction of an optical path P from the subject S, observation position moving means 7 for moving the optical path changing means in a different direction with respect to a straight line connecting the imaging part 42 and the subject S, and observation angle control means 8 for controlling angles θ1 and θ2 of the optical path changing means accompanying the movement of the optical path changing means.SELECTED DRAWING: Figure 1A 【課題】治療用器具に遮られて観察不可能な部位の観察をすることができるマイクロスコープを提供することを課題とする。【解決手段】マイクロスコープ3は、被写体Sを観察する第1観察光学系4と、第1観察光学系4によって被写体S観察する向きが異なり、第1観察光学系4の撮影部42を共有する第2観察光学系5と、を備えている。第2観察光学系5は、被写体Sからの光路Pの方向を変換させる光路変更手段と、光路変更手段を、撮影部42と被写体Sを結ぶ直線に対して異なる方向に移動させるための観察位置移動手段7と、光路変更手段の移動に伴って、光路変更手段の角度θ1,θ2を制御する観察角度制御手段8と、を具備する。【選択図】図1A
