７′は対物レンズ、８，８′は接眼レンズである。 In view of the above points, the present invention aims to provide a fiberscope with a small diameter that can provide stereoscopic vision.This will be explained below with reference to an embodiment shown in the drawings. A light source, 2 and 2' are condenser lenses, and 3 is a reflecting mirror that is rotatably arranged around an axis 4 and has a transmission aperture 3a, 5 and 5'
is the image guide, 6, 6′ is the prism, 7,
7' is an objective lens, and 8 and 8' are eyepiece lenses.

従つて、接眼レンズ８，８′を両眼で覗くと、眼
の残像作用により一様の光覚を生ずるので、両眼
による観察部位の立体視が行なわれ得る。 Since the embodiment of the present invention is constructed as described above, in the illustrated state, the light emitted from the light source 1 passes through the condensing lens 2, is reflected by the reflecting portion of the reflecting mirror 3, and is reflected by the end surface 5a of the image guide 5. The light that passes through the image guide 5 and exits from the other end face 5b passes through the prism 6 and the objective lens 7 to illuminate the area to be observed. The reflected light from the thus illuminated observation area forms an image on the end surface 5'b of the image guide 5' via the objective lens 7' and the prism 6', passes through the image guide 5', and forms an image on the other end surface 5'. The light emitted from a passes through the transmission aperture 3 of the reflecting mirror 3.
a and is observed through the eyepiece 8'.
Next, when the reflector 3 is rotated 180 degrees around the axis 4,
The light from the light source 1' passes through the image guide 5' and is used as illumination light, and the illuminated observation area is observed through the image guide 5 and the eyepiece 8. Here, the reflection mirror is not rotated at a constant angular velocity, but is rotated by, for example, a stepping motor or the like so that the mirror is stopped for a certain period of time necessary for producing an afterimage when the aperture reaches a predetermined position.
Therefore, when the eyepieces 8, 8' are looked into with both eyes, a uniform light perception is produced due to the afterimage effect of the eyes, so that stereoscopic vision of the observed region can be performed with both eyes.
上述の如く本発明によれば、二本のイメージガ
イドを交互にライトガイドとして利用することに
より、直径の小さい立体視フアイバースコープを
構成することができ、また構成が簡単で且つ安価
に製造し得る等の効果がある。 As described above, according to the present invention, by alternately using two image guides as light guides, it is possible to construct a stereoscopic fiberscope with a small diameter, and the structure is simple and can be manufactured at low cost. There are other effects.
尚、以上の説明では反射鏡に一個の透過開口部

円周上にある開口部を有する反射鏡を適当な角度
だけ間欠駆動するようにしてもよい。 Although the above explanation deals with the case where the reflecting mirror is provided with one transmission aperture, it is also possible to intermittently drive a reflecting mirror having a plurality of apertures located on the same circumference by an appropriate angle. good.
