In the past, single focus cameras were used as such compact cameras.

In the monofocal type camera, a plurality of lenses through which an image of a subject is transmitted and an image sensor for capturing the transmitted image are fixed integrally.

In the case of such a camera, all the components were fixed to the inside of the case and blocked from the outside, and only the frontmost lens was exposed to the outside.

Therefore, only the front lens was dusty, and there was a risk of blurring the image quality of the image captured by the image sensor. When the user cleaned the front lens, the user could obtain a clear image.

Recently, at the request of users, a function of auto focusing and zooming even in a small camera has been added.

In order to perform such auto focusing and zooming, the distance between each lens and the distance between the image sensors must be adjusted, and each lens must be mechanically driven.

Therefore, such a functional small camera is equipped with a complex drive unit inside, unlike the past miniature small cameras can not close the interior.

As a result, foreign matter penetrates into the camera through an opening that is opened to allow light to pass through, and the foreign matter penetrates the operating performance of components of the driving unit. Particularly, when fine dust adheres to the image sensor, the image quality is extremely reduced, which is incomparable with foreign matter on the lens. In addition, when dust adheres to the image sensor, the dust cannot be cleaned and the entire camera cannot be used.

Therefore, there is a need for a device that blocks foreign matter from the opening before foreign matter penetrates into the camera.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object of the present invention is to be provided in an opening of a small camera, by opening the opening only when using the image shooting function and closing the opening when not using the image shooting function.
