Description
本發明關於一種鍵盤，尤其是關於一種使用光學式按鍵開關之發光鍵盤。 The present invention relates to a keyboard, and more particularly to an illuminated keyboard using an optical push button switch.
發光鍵盤係指於鍵盤內設置發光手段以照亮按鍵之鍵盤。請參閱圖1習知技術之發光鍵盤之按鍵立體分解圖。習知的發光鍵盤之按鍵90由電路板94、發光元件91、按鍵外殼92、透光孔921以及鍵帽93所組成。按鍵外殼92以及鍵帽93設置於電路板上方。電路板94上設置發光元件91，發光元件91例如為一發光二極體，並且在按鍵外殼92上開設透光孔921，以便發光元件91的照明光線911通過按鍵外殼92，並且透光孔921中設置有導光件922協助傳導照明光線911，用以使光線911傳導出鍵帽93外，達成使按鍵發光的效果。 The illuminated keyboard refers to a keyboard that is provided with a light-emitting means in the keyboard to illuminate the keys. Please refer to the perspective exploded view of the button of the illuminated keyboard of the prior art. The button 90 of the conventional illuminated keyboard is composed of a circuit board 94, a light-emitting element 91, a button housing 92, a light-transmitting hole 921, and a key cap 93. The button housing 92 and the keycap 93 are disposed above the circuit board. A light-emitting element 91 is disposed on the circuit board 94. The light-emitting element 91 is, for example, a light-emitting diode, and a light-transmitting hole 921 is formed in the key housing 92 so that the illumination light 911 of the light-emitting element 91 passes through the button housing 92, and the light-transmitting hole 921 A light guide 922 is disposed to assist in conducting the illumination light 911 for conducting the light 911 out of the keycap 93 to achieve the effect of causing the button to emit light.
由於習知按鍵90的透光孔921的開孔範圍小而限制照明光線通過，導光件922也因為出光位置被透光孔921的開孔限制而變小，造成無法傳導出大量的光線，同時傳導出來的光線集中在透光孔921的位置周圍，使光線911不能均勻的擴散傳導出鍵帽93至外界。因此無法有效的傳導照明光線。此外，進入到按鍵內部的照明光線也容易散失。不僅浪費掉大部分的照明光線，同時也降低照明能力。因此，習知技術的發光鍵盤與按鍵仍 然有許多需要改善的地方。 Since the aperture of the light-transmitting hole 921 of the conventional button 90 is small to limit the passage of the illumination light, the light guide member 922 is also small because the light-emitting position is restricted by the opening of the light-transmitting hole 921, so that a large amount of light cannot be transmitted. At the same time, the conducted light is concentrated around the position of the light-transmitting hole 921, so that the light 911 cannot be uniformly diffused and transmitted out of the key cap 93 to the outside. Therefore, the illumination light cannot be effectively transmitted. In addition, the illumination light entering the inside of the button is also easily lost. Not only does it waste most of the lighting, but it also reduces lighting. Therefore, the conventional technology of the illuminated keyboard and buttons still There are many places for improvement.

接下來詳細說明本發明按鍵20產生按鍵開關電子訊號的流程。續請參閱圖5本發明第一較佳實施例之按鍵觸發訊號之作動示意圖。該第二反射件27連接於該觸發柱23的底面，並且該觸發柱23帶動該第二反射件27進行位移。當按鍵20處於未被觸壓的狀態時，觸發柱23因尚未被觸壓而位於一第一位置S1。電路板10上的光發射器12發射感測用光線X經由第一透孔226進入殼體22內。感測用光線X照射到第一反射件26，並且被第一反射件26反射。由於觸發柱23位於第一位置S1，使第二反射件27無法接收到第一反射件26所反射的感測用光線X，因此不產生電子訊號131。當按鍵20被觸壓時，觸發柱23被按壓而移動到一第二位置S2。使第二反射件27接收第一反射件26所反射的感測用光線X，並且第二反射件27將感測用光線X反射至第二透孔227，使感測用光線X穿出殼體22之外並且進入光接收器13中。光接收器13接收到感測用光線X之後產生一電子訊號131。同時，為了避免感測用光線X受到周圍其他雜光的干擾導致光接收器13接收時產生誤差或訊號誤判，當感測用光線X穿出殼體22後會先通過濾光片28。濾光片28將濾除對感測用光線X形成干擾的其他周圍光線。之後，經過過濾的感測用光線X再照射至光接收器13中產生電子訊號131。 Next, the flow of the button 20 generating the button switch electronic signal will be described in detail. Continuing to refer to FIG. 5 is a schematic diagram of the operation of the button trigger signal according to the first preferred embodiment of the present invention. The second reflector 27 is coupled to the bottom surface of the trigger post 23, and the trigger post 23 drives the second reflector 27 to be displaced. When the button 20 is in an untouched state, the trigger post 23 is located at a first position S1 because it has not been touched. The light emitter 12 on the circuit board 10 emits the sensing light X into the housing 22 via the first through hole 226. The sensing light X is irradiated to the first reflecting member 26 and is reflected by the first reflecting member 26. Since the trigger post 23 is located at the first position S1, the second reflecting member 27 cannot receive the sensing light X reflected by the first reflecting member 26, and thus the electronic signal 131 is not generated. When the button 20 is pressed, the trigger post 23 is pressed to move to a second position S2. The second reflecting member 27 receives the sensing light X reflected by the first reflecting member 26, and the second reflecting member 27 reflects the sensing light X to the second through hole 227, so that the sensing light X passes through the shell. Outside the body 22 and into the light receiver 13. The optical receiver 13 generates an electronic signal 131 after receiving the sensing light X. At the same time, in order to prevent the sensing light X from being disturbed by other surrounding stray light, the optical receiver 13 generates an error or a signal misjudgment. When the sensing light X passes through the casing 22, it passes through the filter 28. The filter 28 will filter out other ambient light that interferes with the sensing light X. Thereafter, the filtered sensing light X is again irradiated to the light receiver 13 to generate an electronic signal 131.
該光發射器12較佳可以為一紅外線光源件。該感測用光線X為一紅外線。光接收器13為一紅外線接收器。該濾光片28為一紅外線濾光片。 The light emitter 12 is preferably an infrared light source. The sensing light X is an infrared ray. The light receiver 13 is an infrared receiver. The filter 28 is an infrared filter.

When the button 80 is triggered, as shown in FIG. The trigger post 84 is displaced downward while the first contact surface 841 continues to contact the second contact surface 831 so that the illumination light 711 can be continuously conducted from the light guide 83 into the trigger post 84, so that the illumination light 711 can be continuously Conducted to the keycap 81.
為了防止照明光線711散失，本第四較佳實施例更包括一反光層824。該反光層824設置於殼體82中並且形成一反光空間825。本實施例之反光層824以及反光空間825之設置與光反射流程與第一較佳實施例相同，因此就不再多贅述。 In order to prevent the illumination light 711 from being lost, the fourth preferred embodiment further includes a light reflecting layer 824. The light reflecting layer 824 is disposed in the housing 82 and forms a reflective space 825. The arrangement of the light reflecting layer 824 and the reflective space 825 of the present embodiment and the light reflection process are the same as those of the first preferred embodiment, and thus will not be further described.
本發明將照明光線111傳導至觸發柱23之周緣發散，以及將照明光線111經由觸發柱23本身發散穿過鍵帽21。使照明光線111能集中於鍵帽21中間並且提高導光效果。同時殼體22內部的反光層224能防止照明光線111散失。能夠解決習知技術之問題。 The present invention conducts the illumination light 111 to the periphery of the trigger post 23 and diverges the illumination light 111 through the trigger cap 23 itself through the keycap 21. The illumination light 111 can be concentrated in the middle of the keycap 21 and the light guiding effect is enhanced. At the same time, the light reflecting layer 224 inside the casing 22 can prevent the illumination light 111 from being lost. Can solve the problems of the prior art.
上所述僅為本發明的較佳實施例，並非用以限定本發明的權利要求範圍，因此凡其他未脫離本發明所揭示的精神下所完成的等效改變或修飾，均應包含于本發明的範圍內。 The above description is only the preferred embodiment of the present invention, and is not intended to limit the scope of the claims of the present invention, and all other equivalent changes or modifications which are not departing from the spirit of the present invention should be included in the present invention.
