The present invention relates to a flat adjusting device technology capable of matching up focuses of two lights to each other by generating a spherical curved surface and minutely adjusting the same according to a distance to a screen by fixing the center (j) of the rear surface of a flat glass mirror (h), pulling the rectangular edge (g), and pushing the corners. The purpose of the present invention is to solve problems of generating vague image or causing dizziness as the focuses of the two lights are different according to a distance to the screen. In addition, the purpose of the present invention is to solve a problem of additionally preparing the other lens having a curvature per distance and exchanging the lens with the additional lens as an existing concave curved lens is not adjustable. The center of the rear surface of the planar glass reflective mirror is fixated. The problems are solved by a pitch of a screw-thread rotational leader by holding the edge with a holder tip and bending the same by pulling and pushing the sides and vertexes. A function existing prior to the present invention is not capable of completely matching up the two lights with a method of cutting and preparing various curvature variable lenses with a glass processing device and mounting a lens suitable for the distance. If the adjusting device of the present invention is applied, expensive production cost such as expenses for processing the lenses and preparing the various curvature variable lenses is reduced. Therefore, an excellent visibility quality of the lights is obtained. |
