Abstract

PURPOSE:To provide clear images by providing lens cleaners on the lens cap and the lens cover of the camcorder and a still camera, wiping off the surface of an objective lens every time it is opened or closed and photographing an object with a clean lens at all times. CONSTITUTION:The lens cleaners 4 and 5 fixed to the lens cover 1 to be put on the lens part of the main body of a camera by a bearing 2 and a spring 3 are adhered closely to the lens and rotated or slid so that the surface of the lens is wiped clean. Thus, since the lens can be wiped clean every time starting and finishing the use of the camcorder, the object can be photographed in the clear images.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention wipes the dirt of a lens on a lens portion of a VTR integrated camera or a still camera, or a lens cover or a lens cap used for protection and antifouling of the lens. The present invention relates to a structure provided with a wiping device.

[0002]

2. Description of the Related Art Many VTR-integrated cameras and still cameras such as single-lens reflex cameras are provided with a lens cap or a lens cover for protecting the lens and preventing dirt. These are structured so as to cover the objective lens when carrying the camera or when the camera is not used. In addition to this, for example, in models where the lens is built in the camera body (inner lens type), the lens cover moves in conjunction with the camera switch to open when the camera is ON and close when it is OFF. The lens will not be exposed directly when not in use.

Since the lens of the camera is basically made of glass, it is vulnerable to impacts and is not susceptible to dirt. When the objective lens becomes dirty, it is wiped off with a cloth for lens wiping or a lens paper each time. However, when shooting for a long period of time, I did not notice the dirt on the lens, I shot it as it was, and after seeing the image taken later, I noticed dust and dirt on the lens and I failed. . When shooting with a VTR-integrated camera, a still camera, or the like, the image of the subject is input through the lens, and if the lens is left as it is, the sharpness of the image will be lost.

SUMMARY OF THE INVENTION As described in the above-mentioned conventional example, an object of the present invention is to keep a lens of a VTR integrated camera, a still camera or the like in a clean state free from dirt and fogging and to provide a clear image. It's about shooting a video.

[0006]

In order to achieve the above object, a lens cleaner which is conventionally used for lens protection and dust adhesion prevention is provided with a lens cleaner, and when the lens cap is attached or detached, it is rotated or By sliding, the dirt on the lens surface was wiped off.

[0007]

[Function] The lens cap is used to protect the lens and prevent dirt, and is put on the lens when it is carried or not used. Further, the lens cleaner attached to the lens cap wipes off the surface of the objective lens while closely contacting the lens. The lens cleaner should be made of felt, Japanese paper, soft brush, or other material that does not easily scratch the lens surface. These lens wiping parts are removable so that they can be replaced if they become dirty. In the case of a cap type lens cover, the wiping of the objective lens is a rotating operation, but in the case of a shutter type lens cover, the dirt is wiped off by sliding on the lens.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a sectional view showing a lens cap provided with a lens cleaner and a lens portion combined with the lens cleaner. The lens cap body 1 is provided with a bearing 2 and a spring 3 and a lens cleaner body 4 mounted on the back surface of the body 1, and a felt 5 for wiping off the lens. Although the lens cleaner body 4 moves to some extent flexibly by the spring 3, it is made of a sponge or the like between the body 4 and the felt 5 in order to softly hit the felt 5 that comes into close contact with the objective lens 6. Put the absorbent material 11. Before the lens cap is attached, the cleaner unit 5 is brought into close contact with the surface of the objective lens 6 a few times to rotate it. As a result, the surface of the objective lens 6, which has been soiled by hand stains or dust, can be wiped off. Conversely, the lens cap can be rotated a couple of times before shooting to clean the lens before shooting.

FIG. 2 shows a lens portion in the case of a model with a built-in lens. A cleaner section 8 using a brush or butyl rubber is provided at the tip of the lens cover 7, and the surface of the objective lens 6 can be wiped off each time the slide type lens cover 7 is opened or closed.

The present invention is not limited to a VTR integrated camera,
It can also be applied to lens caps for still cameras such as single-lens reflex cameras and compact cameras, or lens covers.

[0012]

According to the present invention, the lens cleaner provided on the lens cap can wipe the surface of the objective lens each time the cap or the cover is opened and closed, and a clear image can be taken.
