しかしながら、上記特許文献１の従来例のものでは、気密性が高い電池室において電池から排出される水素ガスによる電池室変形又は破壊を防止するため、調圧手段により電池室内の気圧を一定気圧以下に保つことは可能であるが、防水型双眼鏡のように水蒸気と水の双方の浸入の防止を図る必要のある観察光学系に対しては、充分に対処し得るものではない。
防水型双眼鏡のような光学装置においては、光学系の収納部に水蒸気が侵入することによって光学系にくもりが生じるため、水の浸入以外にこのような水蒸気の侵入を防止することが不可欠であるが、上記特許文献１ではこのような水蒸気と水の双方の浸入の防止を図る防水構造については考慮されていない。 However, in the conventional example of Patent Document 1, in order to prevent deformation or destruction of the battery chamber due to hydrogen gas discharged from the battery in the battery chamber having high airtightness, the pressure inside the battery chamber is reduced to a certain level or less by the pressure adjusting means. However, it is not possible to sufficiently cope with an observation optical system such as waterproof binoculars that needs to prevent both water vapor and water from entering.
In an optical device such as a waterproof binoculars, it is indispensable to prevent the intrusion of water vapor in addition to the intrusion of water because water vapor enters the optical system housing portion and clouding occurs in the optical system. However, Patent Document 1 does not consider a waterproof structure for preventing the intrusion of both water vapor and water.
