Abstract

(57) [Summary] [PROBLEMS] The present invention makes it possible to easily use a hand-held filter having a plurality of different-diameter screw grooves on a permanent filter of a camera and a front surface of an interchangeable lens body. According to the present invention, a filter having a different diameter can be used without a diameter conversion ring by attaching a plurality of screw grooves of different diameters to the front of a permanent filter body of a camera and a front surface of an interchangeable lens body. By attaching the bulge to the screw groove, a small filter and a large filter can be worn at the same time, and a filter cap suitable for each can be used. In addition, the camera filter can be used for two types of interchangeable lenses by attaching two screw grooves on the rear surface. If the filter is removed from the filter body, it becomes a universal diameter conversion ring, which is very useful when using a filter with a different diameter.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an adapter for a filter of a camera.By attaching several screw threads of different diameters to the front of the filter and the interchangeable lens, filters and caps of different diameters can be used. , Small and large filters can be used together. In addition, the filter can be used for two kinds of interchangeable lenses by attaching two different diameter screw grooves on the rear surface, and if the filter is removed from the main body, it becomes a universal type diameter conversion ring.

[0002]

[Prior art]

 Conventionally, each diameter conversion ring has been used to attach a different diameter filter.

[0003]

[Issues to be solved by the invention]

 The conventional diameter conversion ring can only use one kind of diameter, and when using different diameter filters, each conversion ring must be purchased, the number of parts increases, detachment, sorting, wasteful handling time, etc. It tries to solve the disadvantage of inconvenience.

[0004]

[Means for Solving the Problems]

 In this invention, by attaching several detachable grooves with different diameters to the front of the filter body and the interchangeable lens body, it is possible to use a hand-held filter and to easily install a filter of different diameter without using a conversion ring. Has been resolved.

[0005]

[Embodiment of the invention]

 As described above, by integrating the permanent filter or the interchangeable lens with the diameter conversion ring, a plurality of filters of different diameters can be easily used, and a universal type can be obtained.

[0006]

【Example】

 Hereinafter, an embodiment will be described with reference to the accompanying drawings. 6 is the main body, 1 and 2 and 3 are female screws, so that filters of different diameters can be attached. 4 and 5 are male screws attached to the front of the interchangeable lens that matches the diameter of the screw.

[0007]

[Effect of the invention]

 As mentioned above. In the present invention, several different diameter screw grooves are attached and integrated, so that different diameter filters can be easily attached and detached without using a diameter conversion ring, making it easy to use for a wide range of applications.
