Claims

[Claims for Utility Model Registration] (1) A sealing lid that opens and closes the opening of the camera body; a locking mechanism that locks the sealing lid to the camera body; and an operating section that locks or unlocks the locking mechanism. In the airtight lid opening/closing device for a drip-proof and waterproof camera, a through hole that communicates the inside and outside of the opening is provided near the operating section, and a valve mechanism that opens and closes the through hole, and the operating section and the valve mechanism are provided with a through hole that communicates the inside and outside of the opening. A sealing lid opening/closing device for a drip-proof and waterproof camera, characterized in that the valve mechanism closes when the locking mechanism is in the locked state, and opens when the locking state shifts from the locked state to the unlocked state. (2) In paragraph 1 of the claims for utility model registration,
The operation unit is a drip-proof and waterproof camera lid opening/closing device that is installed on the lid itself. (3) In paragraph 1 of the claims for utility model registration,
The operation unit is a drip-proof and waterproof camera lid opening/closing device installed on the camera body. (4) In paragraph 1 of the claims for utility model registration,
The valve mechanism has a ball inside the through-hole, and this ball opens the through-hole when the operating section is in the unlocked position and closes it when it is in the locked position. (5) Scope of claims for utility model registration, paragraphs 1 to 4
In any one of the items, the airtight lid opening/closing device for a drip-proof and waterproof camera, wherein the through hole is provided with a filter made of an air-permeable waterproof material.
