Claims

[Scope of utility model registration request]

An adjustment ring is attached to the outer periphery of a lens barrel having a first parallel groove parallel to the optical axis and a first inclined groove inclined with respect to the optical axis,
An orthogonal groove extending in a direction perpendicular to the optical axis and a second parallel groove parallel to the optical axis are bored in the adjustment ring, and a roof prism and a focus lens frame for retaining the focus lens are held inside the lens barrel. A first pin that simultaneously fits into the first inclined groove of the lens barrel and the third parallel groove of the adjustment ring is erected on the outer peripheral wall of the focus lens frame, and the prism frame A cam cylinder with a third parallel groove and a guide groove parallel to the axis and a second inclined groove and a third inclined groove is installed on the outside of the prism frame so that it can only rotate freely. A zoom lens frame that holds a zoom lens is inserted inside, and a connecting plate that is slidable only in the optical axis direction is inserted into a guide groove of the prism frame, and one of the second inclined groove or the third inclined groove of the cam cylinder is inserted. and a third parallel groove of the prism frame are separately installed on the outer circumferential wall of the zoom lens frame, respectively.
One of the second pin or the third pin is fitted into the small hole formed in the connecting plate, and the fourth pin is fitted into the first parallel groove of the lens barrel and the orthogonal groove of the adjustment ring at the same time. A zoom monocular characterized by a protruding part.
