In the above structure, the light source body 2 has a part of light that can be introduced into the light guiding element 1' by the light incident surface, and a conventional guided expansion effect is performed in the light guiding element 1 at this time. The periphery 13 背面 of the back surface (corresponding to the opposite side of the light source body 2) is difficult to be affected by the reflection of the aperture 13 on the incident light, and the shadow of the light source body 2 is partially avoided. The light element can be directly projected onto the light-emitting surface 12 without being blocked, so that the light can be refracted at the light-emitting surface 11 of the rear periphery 13Α where the hole 13 is originally shadowed. In the light guiding element 1, the shadow originally generated on the rear periphery 13 of the hole 13 can be effectively eliminated, thereby improving the overall back light quality. In addition, referring to FIG. 4 to FIG. 6, it can be seen that the above structure of the present invention can be combined with at least one circuit board 3, a conductive rubber 4 and a plurality of buttons 5, which are composed of a housing 6 and a cover 60. In the outer casing, a basic structure can be formed, the circuit board 3 is electrically connected to the light source body 2, and the plurality of electrical conduction contacts 31 are respectively disposed on the circuit board 3 corresponding to the light guides. The hole 13 of the component 1 and the elastic support portion 41 of the conductive rubber 4 corresponding to the plurality of protrusions respectively correspond to the hole 13 of the light guiding element 1, so that the elastic portions 41 can pass through the holes 13 970149072 Form number A0101 Page 6/16 pages 0972080070-0 201024849 [0012] m [0013] ❹ [0014] Touch 'and the upper part of each button 5 can be exposed outward through the cover 6Q, The bottom portion (four) of each elastic support portion 41 is provided with a conductive mechanism m. The elastic mechanism of the hybrid support portion u can generate a deformation amount when the button 5 is operated by an external force to electrically conduct the conductive portion and the circuit board 3. 31 contact forms electrical conduction' and when the external force of the operation button 3 disappears, The elastic support portion 11 is elastically deformed portion of the electrically conductive drive return to the original position. In particular, the diameter of the above-mentioned elastic material 41 is usually the largest at the hole position 13, and the smaller the diameter of the button 3 (ie, the top end), the less the light is irradiated by the present invention. It can be minimized by the elastic support portion 41 at the front surface 12 of the light guiding element 1, so that it can also have a certain degree of reduction effect on the shadow of the exposed light = the effect of improving the backlight quality. The invention utilizes the above structure, not only can effectively eliminate the shadow portion located at the periphery of the hole position 13 to improve the overall back (guide) light quality; and at the same time, since it does not need to change the guide wire member 1, the road plate 3 And the main structure of components such as conductive rubber 4 - this will not significantly increase the development and production costs, compared to other technical means that can achieve your function, more in line with the economic benefits of production. It can be seen from the above that the method for eliminating the shadow cast by the light guide member and the device thereof have the effect of eliminating the shadow projection of the hole (4) light, and have indeed been industrially utilized, novel and progressive. However, the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, the equivalent changes and modifications made by the patent application scope of this creation are all covered by the scope of the invention 097149072 Form No. A0101 Page 7/16 Page 0972080070-0 [0015] 201024849 Coverage.
