Claims

[Claims for Utility Model Registration] (1) A frame, a first convex lens attached to the front part of the frame, which is stored in a predetermined storage position along the frame when used at low magnification, and when used at high magnification. When in use, a second convex lens is pulled out from the storage position and stacked close to the inside of the first convex lens; and a second convex lens is pulled out from a groove formed in the frame to the outside of the frame, and a magnification switching knob interlocking with the second convex lens, which slides the second convex lens and switches between low magnification and high magnification by moving the second convex lens; a guide section provided on the frame; a guide mechanism comprising an engaging part provided on a convex lens and engaging with the guide part;
A convex lens passes near the first convex lens and the inner surface of the frame with one surface thereof facing toward the inner surface of the first convex lens and the frame, and passes between the retracted position when the magnification is low and the extended position when the magnification is high. A head magnifying glass, comprising: a guide mechanism that guides the frame to slide; and mounting means that attaches the frame to a user's head. (2) The head magnifying glass according to claim 1, further comprising a light that is detachable from the frame and illuminates the main part of the visual field at the focal length when used at the low magnification and the high magnification. . (3) The head magnifying glass according to claim 1 or 2, wherein the first and second convex lenses are monocular.
