Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens cap provided with a support stand capable of standing upright inside a cap body attached to a camera-integrated VTR with a string.

[0002]

2. Description of the Related Art A conventional lens cap is composed of a cap body, a detachable knob, a lens mounting portion, a cord body, etc., and is used only for the purpose of protecting the lens.

On the other hand, the tripod is generally heavy and bulky, and it is a heavy burden to carry the tripod together with the camera.

For this reason, when a camera is fixed and a picture is taken without using a tripod, the picture can be taken only by placing it on a table, a table, a rock or the like having a high height.

[0005]

Further, the lens cap is an obstacle that is not used during photographing and has a thin meat pressure. Therefore, even if the lens cap is laid under the camera and used as a stand, the front leg of the camera can be used. There is a limit to how high.

Especially when the camera is placed on a flat floor or the ground,
The floor and the ground occupy nearly half of the shooting screen, and people and other people can only shoot their feet, which is not practical.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lens cap capable of lifting a front leg of a camera high during photographing.

[0008]

In order to achieve the above-mentioned object, the lens cap of the present invention is constructed by, for example, as shown in FIG. Further, a hook portion of the camera-integrated VTR may be provided on the support base described above, or a leg protrusion may be provided on the surface side of the cap body.

[0009]

With the lens cap of the present invention constructed as described above, when the lens is protected, the support base is tilted down and housed in the cap body, and the lens cap is used.
When using as a simple tripod, the support base is raised from the cap body, and the legs of the camera-integrated VTR are locked to the support base for shooting. When the hook is provided on the support base, the leg of the camera-integrated VTR can be more reliably locked to the hook.
