An exploded view of the two light transmissive layers _ and the light shielding layer 332·. As shown in FIG. 6 and FIG. 5, the button 62 is mainly different from the button 52 in that the button further includes a second light transmissive layer 620 formed on the lower surface of the key cap 32 (). The color of the first light-transmitting layer 420 is different from the color of the second light-transmitting layer. It should be noted that the secrets of the same reference numerals as those shown in Fig. 5 are the same, and the principle of the same is the same. For example, it is assumed that the color of the first light-transmitting layer 42 is white, the color of the second light-transmitting layer (four) is red', and the light-emitting module 324 emits white light. When the light-emitting module 324 is not illuminated, the user sees that the upper surface 32 of the keycap 320 has a white English letter B'. When the light-emitting module 324 emits white light, the white light passes through the red second light-transmitting layer. 620 and red light. At this time, the user can see an English letter b emitting red light on the surface 3200 above the keycap 32, and an arrow symbol emitting red light. In other words, the present invention can produce different color mixing effects of the M400025 by changing the color of the first light transmitting layer 420 and the color of the second light transmitting layer 620 emitted by the light emitting module 324. Please refer to FIG. 7 'FIG. 7 is a diagram of a button π according to the fifth embodiment of the present invention, wherein FIG. 7( a ) is a cross-sectional view of the button 72, and FIG. 7( b ) is a seventh diagram. An exploded view of the key cap 320, the second light transmissive layer 620, the third light transmissive layer 720, and the light shielding layer 332' in (a). As shown in FIG. 7 and FIG. 6, the button 72 is mainly different from the button 62 in that the button 72 further includes a third light transmissive layer 720 ′ formed between the second light transmissive layer 62 〇 and the opaque layer 332 ′. The color of the first light transmissive layer 420, the color of the second light transmissive layer 62, and the color of the dichroic layer 720 are all different. Further, one portion of the third light transmissive layer 72 is removed to form a fourth pattern 7200' and the fourth pattern 7200 is overlapped and identical with the light shielding layer 332. In a practical application, the third light transmissive layer 72 can be a translucent ink, and the fourth pattern 7200 can be formed by partially removing the third light transmissive layer 72 by laser engraving. In this embodiment, the fourth pattern 72 is the same as the third pattern 3322, which is an arrow symbol, as shown in FIG. In another embodiment, the fourth pattern 7200 and the third pattern 3322 may also be other identical symbols, characters or numbers, depending on the actual application. It should be noted that the components of the same reference numerals as those shown in FIG. 6 have the same principle of operation and will not be described again. For example, it is assumed that the color of the first light transmissive layer 420 is white, the color of the second light transmissive layer 62 is red, and the color of the third light transmissive layer is blue, and the light emitting module 324 emits white light. When the light-emitting module 324 is not illuminated, the user sees the upper surface of the keycapa with a white-white English letter B. When the light emitting module 324 emits white light, the white light passes through the red second light transmitting layer 620 and the blue third light transmitting layer 72〇12 M400025 to form a mixed color light, and the mixed color light passes through the corresponding light transmitting hole 3204. The second pattern 4200 on the keycap 320 is revealed. At this point, the user can see an English letter B carrying the mixed color light. In addition, the light-emitting module 324 emits white light rays first through the third pattern 3322 and the fourth pattern 7200 and then transmits the red second light-transmissive layer 62 and the corresponding light-transmissive holes 3204 to form a red-lighted arrow symbol. At this time, the user can see another arrow symbol with red light on the upper surface 3200 of the keycap 32〇. In other words, the creation can change the color of the light emitted by the light-emitting module 324, and the first light-transmitting layer 42 The color, the color of the second Lu light transmissive layer, and the color of the second light transmissive layer 720 produce different color mixing effects. Please refer to Fig. 8. Fig. 8 is a cross-sectional view of the button 82 according to the sixth embodiment of the present invention. As shown in FIG. 3 and FIG. 8, the button 82 is mainly different from the button 32. The light module 824 of the button 82 can be composed of a light guide plate 8240 and a light-emitting diode 8242. In this embodiment, the light guide plate 824 is disposed under the bottom plate 3, and the light-emitting diode 8242 is disposed adjacent to the light guide plate 824〇. The bottom plate 3 has a through hole 304 corresponding to the key cap .320. The light emitted by the light-emitting body 8242 can be projected to the keycap 320 via the light guide plate 8240 and the through hole 804. It should be noted that the components of the same reference numerals as those shown in FIG. 3 are the same, and the detailed principles are not described herein. In addition, the light-emitting module 324 in FIGS. 4 to 7 can also be replaced by the light-emitting module 824 in FIG. 8 depending on the actual application. In the prior art, the present invention forms a plurality of light-transmissive holes on the keycap, and forms a light-shielding layer having a specific pattern (ie, the first pattern described above) on the lower surface of the keycap, 13 M400025 The emitted light can be cast through the specific pattern of the layer and the corresponding light-transmissive aperture. In this way, the user can see that the specific light is difficult to see by the key towel when the keys and keyboard of the creation are made. In addition, the creation of the Xiangguang module sends out the 'transparent layer of different colors' plus the pattern of the light-transmitting layer and the light-shielding layer = thereby allowing the buttons to have different illumination patterns and different hair color functions. In addition, let the user make the departure state differently, and obtain the visual effect, so as to achieve the purpose of multi-keyboard. Furthermore, since the key cap of the present invention can be made of a metal material, the metal keycap has a better texture when it is worn for a long time.
