Adjusting apparatus of binocular telescope

摘要

An adjusting apparatus of a binocular telescope with a binocular body including a pair of juxtaposed telephoto optical systems is provided. The apparatus includes a diopter adjusting shaft for adjusting a difference in diopter between the pair of juxtaposed telephoto optical systems. The diopter is adjusted by rotating the diopter adjusting shaft to move an objective lens in one of the pair of juxtaposed telephoto optical systems. A focus adjusting shaft for adjusting a focus of the optical systems is also provided. The focus is adjusted by moving the focus adjusting shaft in a direction parallel to an optical axis. The focus adjusting shaft rotates the diopter adjusting shaft to move the objective lenses of the pair of optical systems in an integral manner in an optical axis direction. An operation member for rotating the diopter adjusting shaft and a connecting member for connecting the diopter adjusting shaft and the operating member are provided. The diopter adjusting shaft and the operating member are axially movable relative to one another, and the relative rotation of the diopter adjusting shaft and the operating member is impeded.
