Description

  The present invention relates to a flash light diffusion prevention retrofit part for preventing flash light from being transmitted and diffused into a case when a camera and a photographing device with a small flash are covered with the case made of a light transmissive material.

  In the conventional technical idea, there has been an invention of a case in which a photographing device with a small flash and a camera is covered with translucent rubber, translucent plastic, or the like, but the influence of flash light has not been considered.

  The present invention provides a retrofit case in which a camera and a photographing device with a small flash are covered with a translucent rubber, translucent plastic or the like for protection or cosmetic purposes. It is an object to solve the problem of being reflected in the lens portion and adversely affecting the photographed image.

  According to the present invention, in a retrofit case in which a camera and a photographing device with a small flash are covered with translucent rubber or translucent plastic, the light of the flash passes through the retrofit case and is reflected on the lens portion. In order to prevent this, the problem is solved by sticking a retrofit part made of a light shielding material around the flash part with an adhesive.

  By attaching the retrofit part of the present invention made of a light-shielding material around the small flash part of the camera and the small flash unit of the photographing device with an adhesive material, the inside of the material of the retrofit case made of a translucent material can be obtained. There is an effect of preventing the case end surface of the camera opening portion of the retrofit case from emitting light. When the case end surface of the camera opening emits light, the light receiving condition of the camera portion changes and adversely affects the photographed image. Even if a retrofit case made of a translucent material is attached to the photographing apparatus using the flash light diffusion prevention retrofit part of the present invention, stable flash photography is possible.

It is a bird's-eye view which shows the structure of the retrofit case which consists of an imaging device, the retrofitting prevention part of flash light, and a translucent material. It is a bird's-eye view which shows the state which affixed the anti-flash-diffusion part to the imaging device with the adhesive. It is sectional drawing of the state which attached the retrofit case which consists of translucent material and the retrofit prevention part of flash light to an imaging device. FIG. 4 is an overhead view of FIG. 3. It is sectional drawing of the state which attached the retrofit case which consists of translucent material and the retrofit prevention part of flash light to an imaging device. FIG. 6 is an overhead view of FIG. 5. It is a bird's-eye view of the state where pasted parts for preventing flash light diffusion are attached only around the flash with an adhesive. FIG. 3 is an overhead view of a state in which flashlight diffusion prevention retrofit parts are attached around the flash and around the lens.

  Adhering a flash light diffusion prevention retrofit part made of a light-shielding material that has a slightly larger opening to the same area as the light-emitting part of the small flash, in a small flash part of a camera and a small flash unit Affix with material. Retrofitting parts for preventing flash light diffusion are made by using a light-shielding material for the part material, or by applying a light-shielding treatment to the part to be shielded with a light-shielding paint or printing. When the camera part and the small flash are close to each other, the retrofitting part for preventing the diffusion of flash light interferes with the camera part. A retrofit case covered with translucent rubber, translucent plastic or the like is attached to the photographing apparatus to which the retrofit part for preventing flash light diffusion of the present invention is attached.

  Embodiments will be described below with reference to the accompanying drawings. FIG. 1 is an overhead view showing the configuration. The flash light diffusion prevention retrofit part 2 of the present invention is attached to the photographing apparatus 1 with an adhesive or the like, and then a retrofit case 3 made of a translucent material is attached. 1b represents a camera unit, and 1d represents a small flash. The small flash 1d is disposed near the lens.

Since the camera portion and the small flash are close to each other, the diffusion prevention retrofit part 2 is provided with two cylindrical openings, an opening 2a corresponding to the camera portion and an opening 2b corresponding to the small flash. A retrofit case 3 made of a translucent material has an opening 3a corresponding to the camera portion and the small flash. 3b shows the case end surface of the camera opening. FIG. 2 is an overhead view of a state in which the flashlight diffusion preventing retrofit part 2 of the present invention is attached to the photographing apparatus 1.

  As shown in the cross-sectional view of FIG. 3, since the small flash 1d is disposed near the lens, the flash light diffuses into the retrofit case 3 made of a translucent material. If the case 3 is not attached, the diffused light is blocked by the light-shielding cylindrical part 1c on the outer periphery of the camera part 1b, so that there is no effect. When the retrofit case 3 made of a translucent material is attached without attaching the anti-diffusion retrofit part 2, flash light is transmitted through the case 3 to cause the case end surface 3 b of the camera opening to emit light. The flashlight diffusion prevention retrofit part 2 prevents the flashlight from reaching the case 3.

  Even when the retrofit case 3 is made of a non-translucent material, the flash light is reflected by the rising end surface 3b of the case, so that the retrofit case attachment affects the photographed image. FIG. 4 is an overhead view of a state in which the flashlight diffusion preventing retrofit part 2 of the present invention is attached to the photographing apparatus 1 and a retrofit case 3 made of a translucent material is mounted. The opening 3a of the camera unit and the flash unit is covered with a retrofitting part 2 for preventing flash light diffusion.

  FIG. 5 is a cross-sectional view of an embodiment of the anti-diffusion retrofit part 2 in which a thin flange portion 2e is provided to widen the adhesion area and the anti-diffusion area and provide a cylindrical rise around the flash and around the lens. This is effective when the openings around the case flash and the lens are kept small. FIG. 6 is an overhead view of a state in which the diffusion preventing retrofit part 2 of FIG. 5 is attached and a retrofit case 3 made of a translucent material is attached. 2c indicates rising around the lens, and 2d indicates rising around the flash.

  FIG. 7 shows an embodiment in a state where a flash light diffusion preventing retrofit part 6 covering only the periphery of the flash is pasted. FIG. 8 shows an embodiment in a state where a flash light diffusion prevention retrofit part 6 covering only the periphery of the flash and a light entry prevention retrofit part 7 for preventing flash light from entering the lens are attached. When the lens and the flash are separated from each other, there is an effect of preventing the flash light from being transmitted through the interior of the retrofit case 3 made of a translucent material.
