Abstract
A telescope provided with an automatically opening and closing lens cover which obviates a protective cap attached to the main body. The telescope is provided with a lens hood disposed along a cylinder of the main body in such a manner as to be slidable forward and backward, and two movable lens covers disposed in such a manner as to cover the objective lenses provided at one end of the cylinder. The two lens covers are axially rotatably supported between the objective lenses. A guide pin is attached to the side surface of each lens cover, and a guide groove is provided on the inner surface of the lens hood in such a manner as to be engaged with the guide pin so as to open and close the lens cover by the forward and backward movements of the lens hood. When the lens hood is moved forward and the lens covers covering the objective lenses are opened, thereby enabling observation. When the lens hood is moved backward in this state, the lens covers are replaced to the original position and closed. This structure is also applicable to a monocular telescope.
