Abstract

PURPOSE:To obtain a device capable of grasping an observation position accurately in relation to the reference position of a body to be observed, by providing a freely rotatable reflection optical system and a driving motor in a casing for a side view coupled with an image pickup adapter through an annular window. CONSTITUTION:A cylindrical casing 20 for a side view is coupled through a transparent annular window 17 with an image pickup adapter 16 where an imaging optical system 15 arranged in front of the incidence end surface 13 of an image fiber 11 is fitted. In this casing 20, a reflection optical system 15, such as a total reflection prism 18, guiding an image of a body 14 to be observed to the incidence end surface 13 of the image fiber 11 through the imaging optical system 15, and a driving motor 19 which supports it rotatably are provided. Further, an angle scale 21 is cut around the said window 17, so that the picture 22 of the body 14 and the angle scale 21 are observed simultaneously.
