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.

Abstract

A waterproof housing for storing a camera with a lens barrel includes, a cylindrical lens barrel storage section for storing the lens barrel portion with a through hole communicating the outside and inside of the waterproof housing; and a rotatable cylindrical operation ring supported on an outer periphery of the cylindrical lens barrel storage section and provided to enclose an outer periphery of a rotary ring on the stored lens barrel for rotating the same. The waterproof housing also includes a transmitting member in the hole on an outer wall of the cylindrical lens barrel storage section connected to the rotary ring for directly transmitting rotation of the operation ring thereto, and a waterproof member between the outside of the cylindrical lens barrel storage section and an inner periphery of the operation ring for waterproof between the interior and the exterior of the cylindrical lens barrel storage section.

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...
