In addition, in order to provide each of the various operably controllable button modules provided by the #/domain-substance electronic I, there is still a light guide plate and σ text, and then, the inside of the button module is disposed. The first board and the first source are reflected by the reflection of the direct light guide plate, and the first line of the heart shot can be identified through the ground. Every 1-2 LT can be operated clearly in a dim environment, and it is given; Word, and can easily understand the button module, ==== greatly improved. , shop ^ Jin Ba includes a touch layer, a guide #; tefen a stop (four) 2 touch layer has m and - touch light n light guide plate - the touch light surface of the touch layer The side is formed with - and has a rigid plate body, and the plate body is disposed on the side of the exit-exit surface of the plate body, and the light source is disposed on the light guide plate - and then the j-plane 2:: face The illumination is reflected from the reflective surface of the light guide plate as the surface is emitted; thus, a button module is formed. However, the self-knowledge button module still has the following 5 M313257 in practical use. The problem is that the light guide plate is damaged by the hard speed and the touch is quite bad. The other 4i: Below it is usually equipped with a shrapnel with a plurality of metal shrapnel ^ ^ ^ after the majority of the light board attached to the dust, the pole: two "parts and greatly shorten the use of the light guide plate or button module:: the board for good reflection The effect is that 1 thick product is not easy to be effectively thinned, and it is also related to the electronic device "light, _, r not: seeking contradiction, not only in the assembly and assembly of each component; 22: change:: the material cost of the piece is also One can not be effective [new content] One of the purposes of this creation is to provide a button module, which is used for the finger to press the dance light surface to produce a rapid wear, and the other is in the first board. p ^ 隹 /, ¥ The element that touches the bottom of the board does not produce local permanent deformation, and the service life. A ^ 怂 long ¥ first board or button module to make the light board another purpose - to provide a light guide and use The guide: knows the key module, which not only increases the touch The control layer is pressed and touched, and because of its thin thickness, the assembly and assembly are simpler, and the single and the square are more. The purpose of the above is to provide a light guide plate, a package and a secondary light layer. 'The light-guiding layer is a soft sheet body, and has a reflecting surface' disposed on the reflecting surface with a plurality of light guiding portions for turning the light back 6 M313257 = : is - hard through - and the corresponding materials are included : 2 ^ and 檐 series provide: a kind of button module, (four) face and - formed in the second: the touch layer has - the touch layer below the touch light surface, and the light surface; and the light guide plate is set The light guiding layer is a soft and auxiliary layer, and has a plurality of light guiding portions, so that the auxiliary surface 2: a reflecting surface is disposed on the reflecting surface on the opposite side of the light guiding layer == another, for using the light to The auxiliary light source is disposed on one side of the light guide plate, and the light guide portion reflects the side of the light-emitting/illumination, and then the reflective surface of the light-guiding layer and the [implementation method], the description of the sheep and the technical content are matched. The schema descriptions such as; , , , and the accompanying @式 are for reference and explanation only, and are not intended to limit the work. - 77 _ ..., - and the three figures are respectively for the creation of the light guide plate: the exploded view of the body, the combination of the button modules and the area of the second figure W. ® 'The creation department provides a kind of light guide plate And a button module using the light guide plate. The button module mainly includes a touch layer iq, a light guide plate, and a light source 30, wherein the milk layer 1 can be polycarbonate (Polycarbonate) , PC) material: a contact light surface 12 formed with a pressing surface η and formed under the pressing surface 11, and a key cap 13 of a plurality of protruding protrusions 7 M313257 is formed on the pressing surface n of the present embodiment. The touch bumps 14 are formed on the bottom surface of the touch bumps 14 respectively under the center of the key caps 13 . The light guide plate 20 is disposed under the touch light surface 12 of the touch layer 1 , and includes a light guiding layer 21 and a auxiliary light layer 22 ′. The light guiding layer 21 can be soft such as Silicone. a sheet body having a reflecting surface 211 and a bottom surface 212 formed below the reflecting surface 211, and a plurality of spaced blocks 213 are respectively disposed on the reflecting surface 211 and corresponding to each of the key caps 13 at intervals One or more light guiding portions 214 are respectively disposed in the block 213, and the light guiding portion 214 can be a semi-spherical concave pit as in the embodiment, and the diameter is between 0 0.01 and 0 0.1 awake. The distribution density of the pits in each of the spacers 213 is between Idol: / mm 2 to 20dot / leg 2; and the bottom surface of the light guiding layer 21 is formed with a plurality of touches corresponding to the touch layer 10 The signal bumps 215 of the control bumps 14 are arranged (as shown in the third figure). The auxiliary light layer 22 may be a Thermoplastic Polyurethane Elastomer (TPU), a Polycarbonate (PC), a Polymethyl Methacrylate (PMMA) or a rigid light transmissive sheet such as polyethylene terephthalate (PET), which is superposed on the reflective surface 211 of the light guiding layer 21; and between the auxiliary light layer 22 and the light guiding layer 21 The laminate may be laminated by thermocompression bonding or by glue bonding. The light source 30 is disposed on one side of the light guide plate 20 and may be a light emitting diode (LED); the closer the light guiding portion 214 of each of the spacer blocks 213 of the light guiding layer 21 is to the light source 30 The distribution density of the person is more sparse, and the lighter the light guide portion 214 from the source M313257 30 is denser; the light of the light source 3 is illuminated from the side of the auxiliary light layer 22, and then from the light guiding layer 21 The reflecting surface 211 and the light guiding portion 214 are reflected and illuminated. In addition, the original button module further includes a thin film 4 〇, which is placed under the light guide plate 2 ,, and the elastic film 4 〇 can be a polyethylene terephthalate (PET) material.

Each of the light guide plate according to the present invention and the button module using the light guide plate have the following advantages, since the hard auxiliary light layer 22 is for the human body to press the red button, so it is not easy to be on the surface of the light guide plate. A rapid wear phenomenon occurs. The soft light-guiding layer 21 is attached to the metal elastic piece 42 to be attached to each other. When the Meng-shaped elastic piece 42 is pressed and deformed, the soft light-receiving layer 21 may be known. It is not easy to wear and permanent deformation, and thus greatly prolongs the life of the light guide plate. In addition, by the soft light-guiding layer 21 and the hard light-shielding layer, the light guide plate 20 can not only increase the touch feeling of the key layer 13 of the touch layer 1 but also be thinner than the touch layer 10 by The assembly and assembly of the shrapnel film 40 and the like is simpler and more convenient. .
