Water proof casing

Abstract

The present invention provides a waterproof housing for housing a camera with a lens barrel, which is provided with: a lens barrel housing portion, which accommodates the lens barrel, and has a through hole connecting the exterior and interior of the waterproof housing; The operation ring is supported on the outer circumference of the lens barrel accommodating part, and is provided so as to surround the outer circumference of the rotating ring so as to rotate the rotating ring of the lens barrel accommodated therein, and to be rotatable. In addition, it is also provided with: a transmission part, which is combined with the rotation ring, so as to directly transmit the rotation of the operation ring to the hole provided on the outer peripheral wall of the accommodating cylinder part of the lens barrel; a waterproof part, which It is provided between the outside of the lens barrel accommodating cylinder and the inner circumference of the operation ring for waterproofing between the inside and the outside of the lens barrel accommodating cylinder.

Description

technical field [0001] The present invention relates to a waterproof case for housing a camera with a lens barrel. Background technique [0002] In order to enable the camera to take pictures underwater, a waterproof case that houses the camera watertight has been commercialized conventionally. [0003] This waterproof case is to have, for example, two shell parts supported openably and closably by hinges, and in the state where the hinges are opened, the camera is positioned and accommodated inside the shell parts, and after the accommodation, the two shell parts are sealed watertightly. close up. The waterproof case also has various operating parts so that various operations related to the camera can be performed while the camera is accommodated inside. [0004] However, when the camera is, for example, a single-lens reflex camera, etc., operations related to the lens barrel should generally be possible. Specifically, there is a lens barrel that includes operating rings...

AI Technical Summary

Problems solved by technology

[0008] In the structure described in the above-mentioned Japanese Patent Laid-Open No. 10-123602, in which the operation ring of the lens barrel is rotated by magnetic force, there is a problem that it cannot be followed quickly, and the accuracy of the operation cannot be ensured.

In addition, in the structure described in this publication, since it is necessary to align the position of the magnet on the side of the waterproof camera case with the position of the magnet fixed on the lens barrel of the camera accommodated inside, the operation is troublesome.
