[Prior Art] - Under the continuous advancement of technology, many electronic products are made in the light, thin and short three small volume, such as the current mobile phone and personal digital help and rationale, and the star navigation system. Users can easily carry out on the go. Since the volume of the smashing phone is getting smaller and smaller, in addition to the internal surface of the electric device, the keyboard structure is also thinned. As the keyboard structure tends to be thinner, the technical aspects of making keyboards relative to each other are also improved. The inside of the keyboard structure of the piece = roughly includes: a printed circuit board, a light-emitting element, a first layer, an elastic layer, a button group layer and the like. In the action electric "r吏:::: illuminating element point ^ two rays are projected on the bottom of each button, so that the surface of the button is displayed, allowing the user to display the ring on the surface of the button corresponding to the back end of the light plate Do you add multiple light-emitting elements or a reflector to the number? Plate circumference sentence. As a result, the consumption of electronic products == will also increase. 9 knives and cost M313281 Moreover, the traditional button group layer and the elastic layer or the structure of the button group layer do not have any light shielding layer, so the light-emitting element is spotted, and the light source is projected on the button by the light guide plate. When the light between the buttons is easily interfered with each other, some of the surface numbers or patterns of the buttons are extremely redundant, and some of them are insufficient. Further, most of the elastic layer used in the inner portion of the keyboard structure is made of a rubber material f. Since the rubber material is soft and thin, the rubber material of the elastic layer is easily broken by the frequent pressing of the τ. [New content] Therefore, in view of the traditional lack, this creation proposes a thinned key i, ''σ structure, so that the light source can be concentrated on the button, avoiding the leakage of the light source, and enhancing the rigidity of the elastic layer. So that the keyboard structure is not easily damaged in use, so that the life of the keyboard is increased. In order to achieve the above purpose, the light-transmissive keyboard of the present invention includes: ^ A circuit board, which is a printed circuit board printed with circuit.

The second elastic layer 3 is disposed on the first elastic layer 2, and is composed of a light guide plate 31 and a auxiliary light plate 32. The light guide plate 31 is made of a high light transmissive material such as thermoplastic polyurethane ( Themoplastic Polyurethans, TPU), polycarbonate (p〇iyCarb〇nate, ρ〇, 〇 ( (SHic〇ne), _ Polymethyl Methacrylate (PMMA) or poly(p-ethyl methacrylate) (p〇 Any one of the materials of the lye terephthalate (PET) has a plurality of light guiding particles 311 on the entire surface or the corresponding key cap 51, and the light guiding particles 311 have a concave hole shape, and the light guiding particles 311 can change the optical path. The light entering the light guide plate 31 is refracted at the position of the corresponding key cap 51, and the other surface of the light guide plate 31 is convexly provided with a plurality of convex bodies 312. The protrusions 312 correspond to each of the keycaps 51 and the metal domes 22 as well. The auxiliary light plate 32 is made of polycarbonate of high light transmissive material (p〇lycarb〇nate, _pc) plastic, and is combined with the light guide plate 31 through thermal compression bonding technology in the present drawing, the auxiliary The light plate 32 can enhance the rigidity of the light guide plate 31. The light shielding layer 4 is disposed on the second elastic layer 3, and the light shielding layer 4 has a hollow hole 41 corresponding to the light guiding particle 311, and the gap 53 formed by the key (4) adjacent to the key cap 51 is located in the light shielding layer. 4, to block the interference between the light. The knowledge: the key group 5, is composed of a plurality of key caps μ, each key cap 51 is made of a light-transmitting material, the surface of which is transparent The number of light effects M313281 is f text, symbol, and the bottom is provided with an adhesive layer 52, which is provided with a key cap 51 attached to the light shielding layer 4, and the key cap 51 is formed adjacent to the keycap Μ The slit 53 is located on the light shielding layer 4, so that the light shielding layer 4 can prevent the light from being effectively transmitted by the surface 511 of the keycap 51 from the fourth portion of the slit 53. The light emitting element 6 is laterally illuminated. The light-emitting diode is directly connected to the base 61. The base 61 has a light-emitting (four) disposed on one side of the second elastic layer 3. The light-shielding sheet 7 is located on the light-emitting element 6 and the second elastic layer. The top of the door of the layer 3 'to prevent the light from outside @, while allowing the light to be concentrated into the light guide plate 31. Figure 2, Figure B, is a partial enlarged view of the first keyboard structure of the present invention and a partial enlarged view of Figure 2, as shown in the figure: in the figure, the light generated by the light-emitting portion 62 of the light-emitting element 6 8 after entering the light guide plate 31 of the second elastic layer 2, when the light 8 passes through the light guiding particles 311, the light guiding particles 311 refract the light 8 upward, and then the hollow plate 41 of the light shielding layer 4 is caused by the auxiliary light plate. The light 8 can be projected on the button group 5, so that the surface 511 of each of the keycaps 51 has a light transmitting effect, so that the numbers or characters and symbols of the surface 511 of the keycap 51 can be clearly displayed. At the same time, after the key cap 51 is pressed by the external force, the convex body 312 of the second elastic layer 3 is pressed against the surface 211 of the film elastic piece 21 of the first elastic layer 2, so that the metal elastic piece 22 is deformed and pressed against the circuit board! In the above, the circuit board i generates a signal transmission, and during the pressing of the keycap 51, the metal dome 22 generates a user's feeling of giving a feeling of pressing the keycap 51. M313281 Please refer to the third figure, which is the side view of the first keyboard of this creation. As shown in the figure, the auxiliary light-shielding plate 32 and the light-shielding layer 4 in the figure can be extended to the light-emitting element 3 when the light-emitting element 6 is turned on to prevent the light 8 from being externally introduced into the light guide plate 31. $Making the first line 8 See the fourth picture, which is the second type of keyboard structure of this creation. As shown in the figure, the structure of the keyboard disclosed in the figure is substantially the same as that of the first and second figures, except that the light-emitting element 6a on the circuit board 1 is mounted on the base plate i of the light-emitting element 6a. After the light-emitting portion 62a on the base 61a is introduced through the bottom of the thin light guide plate 31, the light beam 8 passes through the guide 311#, and the light guide particles 311 refract the light 8 to be projected upward, 2 the auxiliary light plate 32 and the light shielding layer. The hollowing out of the 4 makes the light 8 can be projected on the button group 5, so that the surface 5 ι of each key cap 51 has a light transmitting effect, so that the number or the text and the symbol of the surface 511 of the key towel 51 can clearly show the dream. m is a side view of the third keyboard structure of this creation. As shown in the figure: the keyboard structure disclosed in this figure is substantially the same as the first and second figures. The difference is that the circuit board 1 is soldered with - the light 8 is upwardly illuminated. The light-emitting element 6b is soldered. Or fixed to the circuit board, and passed through the through hole 212 of the film spring 21. When the light-emitting component book is directly introduced by the bottom of the light guide plate 31, the light-guiding particle 311 refracts the light δ to the top of the light guide plate 311, and then is supplemented by 10 M313281.
