Abstract: The present invention relates to a binocular having a first operating member and a second operating member for operating a zooming mechanism and a focussing mechanism respectively, wherein the first and second operating members are mounted in a tandem form on a center axis coupling a pair of telescopes, one of the two operating members being operated in a seesaw motion, while the other operating member being operated by rotation. Since the two operating members are apparently distinguishable from each other on the center axis, both the zooming and focussing operations are carried out smoothly and accurately.

Abstract: This invention relates to a binocular in which a focus adjusting ring is built in a central body of the binocular so that it cannot be collided with something rigid. The binocular central body having the built-in focus adjusting ring is rotatably linked with a pair of telescopes by a plurality of screw-type pins.

Abstract: The present invention relates to focus and zoom adjusting levers in a binocular which are mounted in parallel with each other on a center shaft between a left side housing and a right side housing of the binocular body. By turning alternately the above two levers each of which is of a wing shape, a focus and zoom adjustment can be made smoothly and speedily, and a correct object is obtainable.
