Second, after the user presses the button 14, the elastic body 15 is pressed by the button 14. The splicing membrane switch layer 19 allows the circuit in the membrane switch layer 19 to transmit a specific signal (4) to the brain of the corresponding button 14. When the button 14 is pressed, the position of the button n can be made by the elastic restoring force of the body 15. In addition, the miscellaneous keys 14 are ribbed and include a light transmitting region 13〇 directly under the button 14. The light shielding sheet 18 has a light transmitting portion 180, and the different light transmitting portions 18 are coated with different colors. When the light source is incident on the light guide plate 16, part of the light is returned to the light guide plate via the reflective sheet! 6, part of the transfer light board 16 internal transmission. Then, the light is led out to generate color light through the light shielding sheet 18, and the color light passes through the light transmitting area 130' of the bottom plate 13 and finally reaches the key 14. Further, the illuminated keyboard 1 can emit a plurality of colors/lights. As can be seen from Fig. 1, this method must be achieved with additional components (i.e., the light shielding film 18) to produce a backlight of a plurality of colors. However, the more assembly parts add to the cost of zero 5 M334356, the more often the assembly error and the more defective. Nf1, the main scope of this creation is to provide a light guiding module, 1 itself gp color light 'can be used in the keyboard' to make it a luminous keyboard, to solve the [new content] one of the creations of this creation is to provide a kind of Light guide module for the keyboard, light board, reflector and section - (10). The reflective iridium is located on the light guide plate between the reflective sheet and the light guide plate. #色£位 Another aspect of this creation is to provide an illuminated keyboard comprising a light guide, a # 板 plate complex tff, a reflective sheet and a first color zone. The light source is used to emit light and the light is incident, and the number of keys is located above the light guide plate; the light reflection sheet is located under the light guide plate; 1 a color area is located between the light reflection sheet and the light guide plate. In addition, the light guiding module of the present invention and the illuminated keyboard thereof may further comprise a second portion between the reflective sheet and the light guide plate. The color of the second color zone is different: the existing color light module and its illuminated keyboard can emit a variety of color lights, and the advantages and spirit of the present invention can be further solved by the following creation details and drawings. Understanding. [Embodiment] Stealing two A' Figure 2A scales according to the present invention - better implementation f disk 2 level fried map. As shown in Fig. 2A, the illuminated keyboard 2 includes a light guide, a bottom plate 23, a plurality of buttons 24, an elastic body 25, a light reflecting sheet 0, a pupil-color area 262, and a second color area 266. The elastomer 25 is used to support the button 6 M334356 24 and provides an elastic restoring force which acts as the elastomer 15 of the prior art (as shown in Figure 1) and will not be described again. In this embodiment, the light source 22 can be a Light Emitting Diode LED. However, the present invention is not limited thereto, and the light source 22 can also be other light. The light source 22 is used to emit light from one side of the light guide plate 264 to the light guide plate 264; the button / 4 is located above the light guide plate 264; the reflective sheet 260 is located below the light guide plate 264, and the first color region 262 and the second color region 266 are located. The reflector 26 〇 and the light guide 264, it should be noted that the light guide 264, the reflector 26 〇, the first color region 262 and the second color region 266 may be referred to as the light guide module 26 of the illuminated keyboard 2 . In this embodiment, the button 24 has a second light transmissive area 240, and the bottom plate 23 has a first light transmissive area 230. In the actual product design, the first light transmitting region 23A may be a through hole. When the light is led out from the light guide plate 264, the first light transmitting region 230, the elastic body 25, and the second light transmitting region 240 of the button 24 may be sequentially passed. The elastomer 25 can be constructed of a transparent or translucent material such that light can pass directly through the elastomer 25 to the second light transmissive region 240 of the button 24, or light can be diffused by the elastomer 25 around the key 24 and passed through the second The light in the light transmission area is softer. g If the light transmissive area 240 is a symbol and a letter on the button 24, the area in Fig. 2A can emit light. Therefore, when the ambient light source is weak, the keyboard 2 is made to make the different buttons easy to distinguish, so that the user can turn in the hole 5M23 is made of the light-transmissive material (4), and the first light-transmissive area is designed with a little light. In contrast to the fourth embodiment, the second color region 266 is different in color from the first color region 262. The light guide module 26 can display more than one color light, the color region, and the overall color and visual effect are better. Of course, if light, the color of the second color region 266 is the same as the first color region 26 == color first color region mud and the second color region can be plastic material or glass material 7 M334356 piece: or That is, a large color patch having a plurality of color regions is manufactured, and the first color region 262 and the first color region are both of the large color patches. The color zone may be a square (shown) circular, square or other shape. Generally, the shape of the color zone: the shape of the second light transmissive zone of the button 24 soil; the size of the color zone and the distance light , 远22's far and near class, control the color zone _ _ not _ domain reflected or refracted light $. Generally, the area closer to the light source 22 has a smaller area. For example, the area of the first color zone 262 is slightly smaller than the area of the color zone 266. As shown in Figure 2a. The first color zone 262 and the second color zone 266 may also be a color material' and printed on the retroreflective sheeting 260 or the light guide plate. Since the printing technology is very mature, if a single color or a plurality of color regions are to be printed on the retroreflective sheeting 260, a printing step can be added to the production line for manufacturing the retroreflective sheeting 260 or the light guiding plate 264 to produce a single color. Or a reflective sheet or a light guide plate 264 of a plurality of color regions. In addition to printing methods, plating, coating, spraying, inkjet or other coloring methods can also be used. For example, using a spray with a mask, the desired color size and shape can be sprayed on the reflector or light guide. On the 264, it can also be added to the production line of the retroreflective sheet 260 or the light guide plate 264. Please refer to FIG. 2B. FIG. 2B is a schematic diagram showing the light source 22 incident on the light guiding module 26 in FIG. 2A. As shown in FIG. 2b, the light source 22 emits light into the light guiding plate 264 of the light guiding module 26. After the light enters the light guide plate 264 in different directions, the light can be refracted and reflected on the surface of the light guide plate 264, and the partially refracted light can enter the second color region 266'. Then the reflective sheet 260 reflects the light back to the light guide plate 264, and then from the light guide plate. 264, the color light associated with the second color region 266. For example, if the incident light is white light and the color of the second color region 266 is red, the light reflected back to the light guide plate 264 is red light. The first color region 262 and the second color region 266 in FIG. 2B are horizontally arranged, but the color region arrangement is not limited thereto, and it is not necessary to be adjacent, and the color regions may also be vertically arranged to obtain color regions of different colors. The combination, in general, the overlapping of the two different color regions, the overlapping region is the color region of another color. Therefore, the light path in Figure 2B does not mean that the first color region 262 is not M334356 can transmit light, while the second color zone can be applied. Figure 2B only provides silk. The example of the path, the creation is not limited thereto, and the first color zone of the present creation and the second color zone 266 are not necessary to be permeable or opaque. Further, the light source 22 can be a white LED or Other colored LEDs, or even LEDs. By controlling the type of color light that can be emitted by the light source 22, the ugly color regions can also produce different colors of light, for example, if the first color region is muddy and second. Ίί color is red 'into the first color zone 262 with yellow light, the light color reflected by the blue light into the color zone of the two __ color is not the touch color selection of the light source 22 to produce more different _ The illuminating keyboard 1 in Fig. 2 将 ° 1 sets the light transmitting portion 180 between the first Μ 26? ^ 14 .
