Silk keyboard backlight effect. (4) 2 structure, although it can meet the requirements of the basic backlight diffusion of the basic backlight, the factory:; application 'Because the rubber layer 5 has a relatively selected inflammation relative to other components, the thickness of the rubber layer 5 is about 2 mm, and the light guide plate 4 0 thickness and, ",, 〇.125mm) 'to make the overall thickness of the combination is not easy to reduce, so it is not conducive to the small Wei, sensitized design of related products, its overall competitiveness is also difficult to upgrade. See the keyboard backlight combination structure has the above-mentioned shortcomings, the seal maker is researching and improving the shortcomings of these shortcomings, and finally has this creation. [New content] The main purpose of this creation is to provide a keyboard backlight combination improved structure, The utility model can effectively reduce the overall thickness after assembly and is easy to be refined. The other object of the present invention is to provide a keyboard backlight combination improved structure, which has fewer components and a simple assembly procedure, which can effectively reduce production. Cost. In order to achieve the above objectives and effects, the technical means adopted by the present invention include a circuit board with a plurality of shrapnel on one side of the watch, and A light source body is disposed between each of the elastic pieces or on the outer side of the circuit board (not shown); a plurality of buttons having a light transmission function are disposed on one side of the elastic plate of the circuit board and corresponding to the positions of the respective elastic pieces; Reflective film, diffuse moon, silver mesh), reflective M317029 or diffuse or grounding, is set between the circuit board and each button, there are multiple receiving slots on the ★ hai sheet, which can be respectively corresponding The light source body on the circuit board; a light guide plate, having light guiding property, is disposed between the sheet and each button, and the processing surface corresponding to each button needs a light transmitting area on the complex surface, and is in each processing area A plurality of accommodating slots are provided to respectively accommodate the light source body on the circuit board. As for the detailed structure, application principle, function and effect of the present invention, a complete understanding can be obtained by referring to the following description according to the drawings. [Embodiment] The first figure is an exploded view of the structure of the first embodiment of the present invention, and it can be clearly seen from the combined sectional view of the same figure, the main package of the creation includes: a circuit board 1, button 2, sheet 3 (can A part of the circuit board 1 is provided with a plurality of elastic pieces 1 1 on the front side of one of the circuit boards 1 and between the elastic pieces 11 or outside the circuit board (not shown in the figure). The light source body 1 2 (which may be a light emitting diode) is provided, and the plurality of buttons 2 are made of a light transmissive material, which is disposed on one side of the circuit board armature 丄i, and respectively corresponds to the circuit board Each of the elastic pieces 11 and the sheet 3 (which may be a reflective sheet, a diffusion sheet, or a silver mesh) are reflective or diffusive or grounded, and are disposed between the circuit board 1 and each of the buttons 2, The material 3 is provided with a plurality of accommodating grooves 3 1 respectively for accommodating the light source body 1-2 on the read circuit board 1. The light guide plate 3 is made of light guiding property, and is disposed on the sheet 3 Between each button 2, a processing area 41 is provided on the surface thereof, and a light-transmissive area is required corresponding to each button 2, and a plurality of accommodating grooves 4 2 7 M317029 ' are provided between the processing areas 4 1 . The source of the light source body i 2 can be a general-purpose light-emitting diode, or a horizontal full-circumferential light-emitting diode or a lateral light-emitting diode. The part is directly upward, and some of the downward light can be reflected by the sheet 3, and all the menstrual guides 4 are evenly spread, and can be opened at the door of each button 2 to form a uniform backlight effect; and the light guide plate 4 The internal light will be processed ^ 1 = the upper guide 'such ' can be formed in each of the buttons 2 need to be transparent area - compared to the brightness to achieve better lighting effect.
