The step 106 is applied to the protective layer 3. The adhesive 4 can be used for subsequent processing. Referring to the fourth figure at the same time, the step 1〇8 is printed on the above layers: the punching is performed on the punching panel 2 and the panel 2 The groove 27 is used to complete the production of the panel by the position of the two buttons. The tool and the reading of the IS and the six figures are the flow of the keyboard lining sheet of the present invention. As shown in the figure, the method of fabricating the inner liner sheet 5 of the 3⁄4-shaped keyboard is disclosed in the figure. First, a soft substrate such as a C-key is made of a plastic film material. 5: Figure 7A, B' This step 2〇2 is applied to a soft substrate. X. The first layer of white ink is brushed to form a Navigating Key pattern layer 6.

The plurality of hollow light transmission positions at the positions of the dial pattern 25 and the end pattern 26 are also referred to the seventh figure Β, Β, and the step is to print a third layer of white ink on the second baiqin oil to form a reflective layer. ^. a Simultaneously refer to the seventh figure A, B 'This step 208 is based on the second residence system: the second protective layer 7 is printed with a transparent ink " = ; = : protective layer 7, the protective layer 7 can avoid the black凊 凊 第七 第七 第七 第七 β , , , , , , , , 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 第七 凊 凊 第七 凊 凊 第七 第七 第七 第七 第七 第七 第七 第七 第七At the time of processing, please refer to the eighth figure. In step 212, after the above layers are printed, the soft substrate is machine-cut to form a single-liner sheet 5, and the inner liner sheet 5 is produced. 9 and 10 are schematic diagrams of the keyboard structure of the present invention placed in the mold. As shown in the figure: in the figure, the two panels 2 and the inner liner 5 are combined 'and the bottom of the liner 5; The flexible light guiding layer 9. The first step is as follows. In step 300, a protective film 5 is attached to the front surface of the panel 2 after the panel 2 is placed in the mold 10. 1355009 Step 302 'Re-layer 2 After the bonding glue 4 is combined with the lining sheet 5, it is placed in the mold 1 。. Step 304 'filling the mold with rubber (silicone) Referring to FIG. 11 at the same time, the step 306 is after the panel 2 is thermocompression-bonded, the rubber (silicone) is combined with the adhesive of the inner liner sheet 5, and is formed on the bottom of the inner liner sheet 5 to form The light guiding layer 9 is simultaneously exposed by the groove 27 and the light shielding layer 51 and the light reflecting layer 53 of the black ink to the surface of the panel 2 to form a three-dimensional convex rib 54 to divide each one. At the same time, a convex body 91 is formed on the bottom of the light guiding layer 9 corresponding to each button. ^ Please also refer to the twelfth figure, the step 308, the panel 2 is combined with the inner liner sheet 5 and the light guiding layer 9 Then, it is taken out in the mold 1 ,, and the light guiding particles 92 of the plurality of concave holes are formed on the surface of the light guiding layer 9 corresponding to the convex body 91 by laser or the peripheral edge of the convex body 91. The above-mentioned light guiding light is formed. The particles 92 can be condensed by the light source to refract through the hollow light transmitting position 52, so that the number 21, the English letter 22, the various symbols, the non-individual pattern %, the dial pattern 25 and the end pattern 26 on the panel 2 are formed with a light transmitting effect. Referring to the thirteenth figure, the keyboard structure of the present invention is installed in the hand The appearance of the upper perspective I is as shown in the figure: after the keyboard manufacturing of the present invention is completed, the mobile phone 20, and the 'sigma combination, the ribs on the panel 2 are such that there is no gap between the button and the button, so that the external foreign matter (Dust and tiny particles) and water will not enter the inside of the keyboard, so that the surface of the keyboard panel 2 is always kept clean. Please refer to the fourteenth figure, which is a schematic diagram of the use of the keyboard structure of the present invention. The keyboard structure is used in the 8th temple, and the metal elastic piece 91 having the plurality of convex bodies 91 corresponding to the light guiding layer 9 disposed on the elastic layer 3G', the elastic layer 3 is disposed under the elastic layer. 1355009 « » The circuit board 40 has a plurality of conductive contact points 401 corresponding to the metal domes. When the surface of the button 201 of the panel 2 is subjected to an external force, the button 2〇, the lining sheet 5 and the light guiding layer 9 are deformed, and the convex body 91 of the light guiding layer 9 is pressed against the surface of the elastic layer 30. The metal shrapnel Xie deformation contacts the conductive contact point 401 of the thin film circuit board 4, and generates a conduction signal output, and the pattern generated by the signal will be displayed on the display screen of the mobile phone. Referring to the fifteenth diagram, the keyboard structure of the present invention is used on a car dashboard. As shown in the figure, the keyboard panel 2 of the keyboard structure of the present invention can be installed on the dashboard of the automobile in addition to the mobile electronic device, thereby controlling the air-conditioning system, the audio-visual system and the satellite navigation system, etc. The preferred embodiments of the present invention are not intended to limit the scope of the present invention.
