PURPOSE:To enable to observe inner skin cells of a horny coat in the same eye sight over a broader range, by providing a rotating body or the like with slits substantially in parallel with a plane through the 1st lens light axis located near an inspected body. CONSTITUTION:The 1st lens 11 can be located near the position of a body to be inspected 10, the 2nd and 3rd lenses 12, 13 are located at the back of the 1st lens 11 from the body 10 so that they are symmetrical to both the sides of a specified plane 14 passing through the light axis of the 1st lens. A rotating body 15 consists of a short cylindrical surrounding wall 16 and a side wall 17 to choke its one end, and the side wall is provided with slits 20 in parallel with the plane 14. Since the moving speed of the slits 20 is faster than the video storage speed by the eyes of the observer, the observer can see the image of the body 10 over the entire eye sight of an observing optical system 26. |
