Since the environment and timing of the computer system are becoming more and more diverse, the keyboard device must also evolve to meet the needs of users. In the dark environment, in order to allow the user to break the position of each button on the keyboard, a variety of keyboards with luminous capabilities have been developed. - For example, U.S. Patent No. 5,936,554, U.S. Patent No. 7,278,750, the disclosure of which is incorporated herein by reference. The device's LEDs are provided in a button to provide a light source to a single button, allowing the user to clearly identify the individual buttons in the dark or in low light. Although such an illuminated keyboard device can solve the problem that the button cannot be clearly recognized in the darkness, the current standard keyboard configuration has more than one hundred buttons, and if it is necessary to have a corresponding light-emitting diode in each button The body 'will increase the number of the overall keyboard components', which not only increases the manufacturing process and cost, but also makes the product less lightweight. In addition, the power consumed by a large number of light-emitting diodes and the heat generated by the same cause the user's troubles.

The illuminating keyboard respectively discloses that a plurality of illuminating back plates such as an electroluminescent sheet and an optical fiber panel are added above or below the bottom plate of the keyboard, so that the g key is located above the illuminating back board. Light is emitted for the user to recognize the location. Although the illuminated keyboard can uniformly illuminate the entire keyboard through a single illuminating backboard, compared with the above-mentioned illuminating keyboard disposed inside the button, the internal components can be easily assembled and facilitated assembly, and the power consumption of the electroluminescent panel and the optical fiber sheet is reduced. The amount is very low and low, which is beneficial to the long-term use of smoke. In addition, as disclosed in the Patent No. 1269333 of the Republic of China and the application No. 1/288,258 of the United States, a keyboard having a backlight structure is disclosed, and a light source conducting space is defined between the bridge board and the bottom plate below, and The bridge board is provided with at least one light guiding portion corresponding to the light source at the keyboard portion, and the light source receiving the light source entering the light source conducting space is introduced into the keyboard portion to form the keyboard.

The keyboard unit 10 includes a plurality of pressing members 11 for pressing by a user, and an interlocking mechanism 12 disposed under the urging surface of the pressing member 11 and providing a displacement stroke of the pressing member 11 in accordance with the biasing direction. The interlocking mechanism 12 has an elastic member 13 for allowing the pressing member 11 to reciprocate up and down. The substrate 20 has an assembly portion 21 for the other end of the linkage mechanism 12, so that the keyboard portion 10 is disposed on the substrate 20. In this embodiment, the substrate 20 includes a bridge 22 provided with the assembly portion 21 and a circuit board 23 that is triggered by the displacement of the pressing member 11 to generate a command signal. The surface of the substrate 20 has at least one light guiding groove 24, and a light channel for conducting the light source is formed in the light guiding groove 24, the light guiding groove 24 and the pressing member 11 and the substrate The light-emitting spaces 31 formed between the two have a light-conducting relationship with each other. An illuminator 30 is disposed on the substrate 20 to generate light input into the light guiding groove 24 to cause light to travel in the direction of the light path. The illuminator 30 can be placed at the end of the light guiding groove 24, as shown in FIG. 1 or can be disposed in the light guiding groove 24, as shown in FIG. 4, to provide light to In the light guiding groove 24. [0010] At least one inner wall surface of the light guiding groove 24 is a reflective surface. In the present embodiment, as shown in FIG. 3-1, the light guiding groove 24 has two reflecting surfaces, which are a first reflecting surface 241 and a second reflecting surface 242, respectively. In order to enable the light in the light guiding groove 24 to be radiated into the surrounding light-emitting space 31, the light guiding groove 24 has a V-shaped or U-shaped structure, and the first reflecting surface 241 or the second reflecting surface 242 with respect to the surface of the substrate 20 has a single-numbered A No. 101 page 6 / 19 pages 1013323964-0 has a reflection angle of 0. The reflection angle 0 叮 is between 180 ° and 0 ° and the first reflection The surface 241 and the second reflective surface 242 have a reflective layer 243 thereon. When the illuminator 30 generates light into the light guiding groove 24, the light may be on the first reflecting surface 241 due to the reflection angle of the first reflecting surface 241 or the second reflecting surface 242. And passing back and forth between the second reflective surface 242 to move the light along the direction of the light guiding groove 24 to the distal end; on the other hand, the light guiding groove 24 is electrically connected to the pressing member 11 and the substrate The light-emitting space 31 ′ formed between the 20 ′, the reflection angle 0 can also make the light and the first reflective surface 241 or the second reflective surface

The pressing member 11 is provided with brightness. In addition, an inner wall surface of the light guiding groove 24 may be a reflecting surface 246. As shown in FIG. 3-2, in the embodiment, the reflecting surface 246 has a reflection angle with the substrate 20. 0, the reflection angle 61 can be between 180. To 〇. A reflective layer 243 is also disposed on the reflective surface 246. When the light enters the light guiding groove 24, the light is obliquely reflected by the reflecting surface 246 to the pressing member 11 in the light emitting space 31. [(5) (1) When light is transmitted through the illuminator 30, the brightness may be reduced because the distance is transmitted farther. Therefore, in another embodiment of the present invention, as shown in FIG. 5, the depth of the light guiding groove 24 decreases as the distance from the illuminator 30 increases. That is to say, when the light enters the light guiding groove 24, the farther the light guiding groove 24 is, the shallower the depth of the light guiding groove 24 is, so that the light guiding groove 24 can be reflected. The space becomes smaller 'to make the light more easily diverge into the illuminating space 3 ,, so that the illuminating state of the overall keyboard is uniformized. In this embodiment, the light guiding groove 24 has at least a smooth ramp 244 to adjust the depth of the light guiding groove 24 (page 7 / total 19 pages 97712686 # " single number Α 0101 1013323964-0 1380193 __ 101 On August 24th, the page is replaced by the positive page. Alternatively, the light guiding trench 24 may have at least one stepped structure 245 (as shown in FIG. 6) such that the further the distance from the illuminator 30 is, the light guiding trench 24 has a shallower depth. [0012] In summary, since the keyboard with the light-emitting structure of the present invention only needs to provide a few illuminators, the light-transmitting groove can be used to diverge the light below the light-emitting space under the keyboard portion, thereby reducing the number of light-emitting components. And reduce the thickness of the entire keyboard to achieve the purpose of thinning. Further, in the light guiding groove, the depth of the groove is adjusted in accordance with the change in the distance between the light guide, so that the light emitting space has uniform brightness. Therefore, the present invention is extremely progressive and meets the requirements for applying for an invention patent, and the application is made according to law, and the praying bureau has granted the patent as early as possible. The present invention has been described in detail above, but the foregoing is only a preferred embodiment of the invention, and is not intended to limit the scope of the invention. That is, the equivalent changes and modifications made by the scope of the present application should remain within the scope of the patent of the present invention.
