| 摘要 |
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.
