Claims

[Scope of utility model registration request]

In a telescope that incorporates a convex lens on the objective side of the lens barrel and a concave lens on the eyepiece side, a long main body lens barrel has a joint surface that tilts the lens barrel at an angle of 45 degrees with respect to the central optical axis of the lens barrel. and a short eyepiece tube, a circular hole centered at the intersection of the joint surface and the optical axis is provided in the inclined joint surface of the main body barrel, and a circular hole is provided in the inclined joint surface of the eyepiece tube. A coupling port that rotatably engages with the circular hole is protruded, and the eyepiece barrel is concentrically connected to the main body barrel in a telescope in which the optical axis of the concave eyepiece lens and the optical axis of the convex objective lens are aligned on a straight line. It is joined so that it can be rotated to switch between a matching state and a right-angled pointing state when using a periscope, in which the optical axis of the eyepiece is perpendicular to the optical axis of the convex objective lens, and the internal position is close to the inclined joint surface side of the main body lens barrel. A first position is rotatably switchable between an escape position in the lens barrel parallel to the optical axis of the convex objective lens and a position in the junction port that is inclined at an angle of 45 degrees with respect to the orthogonal optical axes of the convex objective lens and the concave eyepiece lens. In addition, the lens barrel in which the convex objective lens of the main body barrel is incorporated can be manually rotated around the optical axis of the lens, and the optical axis of the convex objective lens and A second reflecting mirror that can be rotated to switch between a parallel lens barrel escape position and a lens facing position tilted at an appropriate angle with respect to the optical axis of the objective convex lens is fitted and mounted in a rotating lens frame. A telescope that doubles as a periscope.
