Abstract

The binocular system 100 includes monoculars 10, 20 in pairs and a coupling portion 30 coupling the monoculars 10, 20 in pairs, wherein: one monocular 10 has a connecting portion 11 on a side of an objective lens 13 thereof; the other monocular 20 has a connected portion 22 connectable to the connecting portion 11 on a side of an eye lens 24 thereof; the coupling portion 30 includes a first coupling portion 31 formed integrally with the one monocular 10, a second coupling portion 32 formed integrally with the other monocular 20, and a hinge portion 33 coupling the first coupling portion 31 and the second coupling portion 32 in such a manner that a mutual bending angle therebetween is adjustable centering around a bending axis B; and the one monocular 10 and the other monocular 20 are detachable from each other.

Dependent claims

A binocular system comprising:

monoculars in pairs;
and
a coupling portion coupling the monoculars in pairs,
wherein:
one monocular has a connecting portion on a side of an objective lens thereof;
the other monocular has a connected portion connectable to the connecting portion on a side of an eye lens thereof;
the coupling portion includes a first coupling portion formed integrally with the one monocular, a second coupling portion formed integrally with the other monocular, and a hinge portion coupling the first coupling portion and the second coupling portion in such a manner that a mutual bending angle therebetween is adjustable centering around a bending axis;
and
the one monocular and the other monocular are detachable from each other,
wherein the hinge portion has a shaft member movable forward and backward in a direction of the bending axis, the shaft member being provided at one of the first coupling portion and the second coupling portion, and
wherein the other one of the first coupling portion and the second coupling portion has at least one engaged portion which is a recess engageable with the shaft member.
