Description

  The present invention relates to a cover for protecting a camera lens of a mobile phone with a camera incorporating a digital still camera.

  In recent years, mobile phones equipped with a small camera and can be used as a digital still camera have been developed and boast an explosive share.

  In this type of mobile phone having a camera function, the camera lens is always exposed on the surface of the main body regardless of whether or not the camera is used in the camera mode. Accordingly, there are disadvantages that dust and dirt are easily attached to the surface of the camera lens, and further, the surface of the camera lens is easily damaged.

In order to eliminate such drawbacks, a lens cover has been developed that is movable with respect to the mobile phone body or detachable from the mobile phone body and can cover the front surface of the camera lens (for example, (See Patent Documents 1 and 2).

  Since this type of lens cover must be movable with respect to the mobile phone body or detachable from the mobile phone body, it must be structurally large, and the front of the camera lens must be If the parts to be covered are attached to the main body of the mobile phone, there is a drawback that it is bulky.

  An object of the present invention is to provide an extremely simple type of lens cover that is not such a large lens cover and that can be easily attached to a camera lens.

  In order to achieve this object, in the present invention, the layer 2 is of a type that is adhered to the surface of the camera lens b of the camera-equipped mobile phone B, and the elastic layer 2 is provided on the surface of the fiber base 1. The hole 3 is provided near the center of the base material 1 and the elastic layer 2, and the adhesive layer 4 is provided on the back surface of the base material 1 excluding the hole 3.

  The lens cover A is attached to the surface of the camera lens b of the mobile phone B, and can protect the surface. The lens cover A can be attached to the surface of the camera lens b very simply by simply overlaying the adhesive layer 4 provided on the back surface of the substrate 1 on the surface of the camera lens b of the mobile phone B. .

  It is preferable that the fiber base material 1 is made of an elastic material having ultrafine fibers as a main raw material. When a fiber base material having such performance is used, the fiber base material itself has elasticity, and is suitable for protecting the camera lens b.

  It is preferable that a luminous material is contained in the elastic layer 2. A phosphorescent material is a material that absorbs and accumulates sunlight, fluorescent lamps, and other light and emits light in the dark, and is included in the elastic layer 2 Therefore, the lens cover A attached to the surface of the camera lens b of the mobile phone B emits light in the dark, so that the mobile phone B can be easily confirmed in the dark.

  It is preferable to provide a release paper 5 on the back surface of the pressure-sensitive adhesive layer 4. When the lens cover A is attached to the surface of the camera lens b of the mobile phone B, the release paper 5 may be peeled off. If the release paper 5 is not peeled off, the pressure-sensitive adhesive layer 4 does not appear, which is advantageous in terms of storage and other aspects of the lens cover A, and the life of the pressure-sensitive adhesive layer 4 can be maintained long.

  If the lens cover of Claim 1 is used, the surface of the camera lens b of the mobile phone B can be protected. By simply overlaying the pressure-sensitive adhesive layer 4 provided on the back surface of the fiber base material 1 on the surface of the camera lens b of the mobile phone B, it can be very easily attached to the surface of the camera lens b.

  If the lens cover according to claim 2 is used, since the fiber base material 1 itself is also elastic, it is suitable for protecting the camera lens b.

  If the lens cover described in claim 3 is used, the mobile phone B can be easily confirmed in the dark.

  If the lens cover according to claim 4 is used, the lens cover A can be attached to the surface of the camera lens b of the mobile phone B very simply by simply peeling off the release paper 5. Since the release paper 5 is provided, it is advantageous in terms of storage and other aspects of the lens cover A, and the life of the pressure-sensitive adhesive layer 4 can be maintained long.

A preferred embodiment of the lens cover will be described in detail with reference to the drawings.
The lens cover A can be attached to the surface of the camera lens b of the camera-equipped mobile phone B. The drawings illustrate the case where the present invention is applied to a cellular phone that can be folded in two, but it is needless to say that the present invention can also be applied to an integral cellular phone.

  The lens cover A is a laminated body having a disk shape having a diameter of about 10 mm and a thickness of about 2 mm in accordance with the shape and size of the camera lens b of the camera-equipped mobile phone B, and the surface of the fiber substrate 1 is made of silicone. An elastic layer 2 is provided. The substrate 1 and the elastic layer 2 have a hole 3 in the vicinity of the center thereof, and the adhesive layer 4 is provided on the back surface of the substrate 1 excluding the hole 3. A release paper 5 is provided on the back surface of the layer 4.

  When the release paper 5 is peeled off, the pressure-sensitive adhesive layer 4 is exposed, so that the lens cover A can be attached to the surface of the camera lens b of the mobile phone B very easily. Since the release paper 5 is provided, it is advantageous in terms of storage and other aspects of the lens cover A, and the life of the pressure-sensitive adhesive layer 4 can be maintained long. Here, a case where a hole communicating with the hole 3 is formed near the center of the release paper 5 is exemplified, but this hole may not be provided.

  The hole 3 is used to expose at least the vicinity of the center including the focal point of the camera lens b when the lens cover A is attached to the surface of the camera lens b of the mobile phone B. Even if it is attached to the surface of the camera lens b, camera photography in the camera mode is possible.

  The fiber substrate 1 is made of an elastic material that uses ultrafine fibers as a main raw material. For example, a polyester ultra-fine fiber is cut short, a non-woven fabric layer is formed on the surface of the thin fabric so as to scrub the paper, the ultra-fine fiber and the thin fabric and the ultra-fine fibers are entangled with each other, and the gap Can be made by impregnating with polyurethane.

Since the fiber base 1 made in this way has elasticity and itself has elasticity, it is suitable for adhering to the camera lens b to protect its surface. In addition, the fiber base material 1 is not limited only to what was illustrated above, As long as it has elasticity, what was manufactured by the other method may be used. A material or the like may be appropriately selected in consideration of the bonding property with the elastic layer 2.

  The elastic layer 2 contains a phosphorescent material. A phosphorescent material is a material that absorbs and accumulates sunlight, fluorescent lamps, and other light and emits light in the dark, and is included in the elastic layer 2 Therefore, the lens cover A attached to the surface of the camera lens b of the mobile phone B emits light in the dark, so that the mobile phone B can be easily confirmed in the dark. The phosphorescent material can be kneaded into an elastic material in either a powder type or a masterbatch type.

  The fiber base material 1 and the elastic layer 2 may be prepared separately, and they may be joined together, or a material having elasticity when forming the elastic layer 2 may be made of a fiber base material. A method of injection molding on the material 1 may be adopted. As shown in FIG. 1 (b), the outer peripheral surface of the disk-shaped lens cover A does not become vertical, but gradually decreases with the upper half going upward, and the lower half is lowered. If the lens cover A is inclined so that it gradually becomes smaller as it goes to, the lens cover A can be easily stuck in the hole surrounding the outside of the camera lens b of the mobile phone B main body.

  Here, the elastic layer 2 is made of a material having at least elasticity, as represented by silicone resin. In the case of a silicone resin, the bonding property with the fiber base material 1 is very good, and it is also convenient to form the layer 2 containing the phosphorescent material. is there. However, it is not limited only to this silicone resin, and examples thereof include vinyl chloride resin, urethane resin, epoxy resin, rubber, elastomer, etc., and the elastic layer 2 is formed even with these materials. Can do.

  The present invention can be applied to all camera-equipped cellular phones capable of taking a picture by setting the cellular phone to the camera mode, and has a mail function, an Internet function, and other various functions. It's irrelevant. That is, when the camera mode of the mobile phone B is selected and the camera lens b is directed to the subject, an image of the subject is formed on the light receiving surface of the image sensor in the main body, and image information obtained by photoelectric conversion is signal-processed. The mobile phone having the function of recording the image data in the memory built in the mobile phone B when the shutter button (not shown) is pressed while viewing the image is displayed on the display unit (not shown). It is possible to apply.
