[0023] 挠性不透光管状件24设置于底表面124与发光单元20之间,挠性不透光管状件24具有第一开口端242及相对第一开口端242的第二开口端244,挠性不透光管状件24以第一开口端242环绕不透光罩22。 [0023] The flexible tubular member 24 is provided a light-tight between the bottom surface 124 of the light emitting unit 20, the flexible opaque tubular member 24 has a first open end 242 opposite the first open end 242 and a second open end 244 The flexible tubular member 24 opaque to the first open end 242 does not surround the translucent cover 22. 于本实施例中,挠性不透光管状件24以第一开口端242紧密套住不透光罩22,使得光线LI自不透光罩22的开口222射出后,不会从第一开口端242处漏出,但本发明不以此为限。 In the present embodiment, the flexible tubular member 24 opaque to the first open end 242 is not caught tightly translucent cover 22, so that the light from LI-impermeable rear opening 22 of the mask 222 is emitted not from the first opening end 242 from leaking, but the present invention is not limited thereto. 例如于实际运用中,第一开口端242与不透光罩22间可存有间隙,只要光线LI不会从第一开口端242处漏出,或是从第一开口端242处漏出的光线LI可忽略(例如不易为人眼所感知)。 For example in practice, a first open end 242 and the translucent cover 22 without a gap there may be, as long as the light does not leak from the LI opening at a first end 242, or leaking from the first open end 242 of the light LI negligible (for example, easily perceived by the human eye). 第二开口端244朝向透光部122,使得光线LI自不透光罩22的开口222射出并进入挠性不透光管状件24后,能再自第二开口端244射出挠性不透光管状件24以朝向透光部122行进,进而穿过透光部122而射出键帽12。 The second open end 244 toward the light transmitting portion 122, so that the light-impermeable mask from the LI 222 of the exit opening 22 and into the flexible tubular member 24 opaque, longer emitted from the second open end 244 of the flexible opaque the tubular member 24 travels toward the translucent portion 122, and then emitted through the light transmitting portion 122 and the keycap 12. 于本实施例中,第二开口端244的边缘完整接触底表面124,故进入挠性不透光管状件24形成的通道内的光线LI亦不会自第二开口端244与底表面124的连接处漏出。 In the present embodiment, the second opening edge 244 of complete contact with the bottom surface 124, so that the light entering LI opaque flexible tubular member 24 formed from the second channel will not open end 244 and the bottom surface 124 of the junction leakage.

[0024] 请一并参阅图4,其为按键结构I于键帽12下压时的剖视图。 [0024] Referring to FIG 4, which is a cross-sectional view of the key structure I keycap pressure at 12. 当键帽12被按压以朝向底板10移动时,挠性不透光管状件24受到键帽12与不透光罩22拘束而扭曲变形。 When the keycap 12 is pressed toward the base plate 10 moves, the flexible tubular member 24 being opaque keycap 12 and the translucent cover 22 without binding and distortion. 由于挠性不透光管状件24具有挠性,故即使于挠性不透光管状件24扭曲变形时,挠性不透光管状件24与不透光罩22及底表面124保持密封状态,挠性不透光管状件24形成的通道仍保持畅通,于该通道内的光线LI仍可顺利地自第二开口端244射出挠性不透光管状件24以朝向透光部122行进,进而穿过透光部122而射出键帽12。 Since the flexible opaque tubular member 24 has flexibility, so even when the twist in the flexible tubular member 24 is not deformed translucent, opaque flexible tubular member 24 and the translucent cover 22 without a bottom surface 124 and remains sealed, the flexible tubular member passageway 24 formed opaque remain clear, in the light path from the second LI can still be smoothly emitted open end 244 of the flexible tubular member 24 opaque to the light-transmitting portion 122 travels toward, and then Cap 12 is emitted through the light transmitting portion 122. 当键帽12被释放(即不再被按压)时,键帽12向上移动回到原位,挠性不透光管状件24亦会恢复原状(于本实施例中,为直筒状),即如图3所示。 When the keycap 12 is released (i.e., no longer being pressed), the upward movement of the keycap 12 back into place, the flexible tubular member 24 will be opaque restitution (in this embodiment, is a straight cylindrical), i.e. As shown in Figure 3. 于实际运用中,挠性不透光管状件24可使用橡胶、硅胶或其他挠性的材料制作,但本发明不以此为限。 In practice, the flexible tubular member 24 may be opaque materials used a rubber, silicone or other flexible, but the present invention is not limited thereto. 例如挠性不透光管状件24与键帽12 —体成型结合(例如一体成型射出),通过对挠性不透光管状件24的管壁厚度的控制亦可获致所需的挠性、弹性,亦即挠性不透光管状件24的刚性小于键帽12的刚性。 Such as a flexible tubular member 24 opaque keycap 12-- binding molded (e.g. molded integrally injection), by controlling the flexibility of opaque wall thickness of the tubular member 24 is also required to obtain induced flexibility, elasticity , i.e. opaque flexible tubular member 12 is less rigid than the key top 24. 于本实施例中,挠性不透光管状件24无论是以独立构件或与键帽12 —体成型,挠性不透光管状件24的第二开口端244均可视为密封连接于底表面124上。 In the present embodiment, the flexible tubular member 24 opaque member either in an independent or keycap 12-- shaping the flexible opaque second open end 244 of the tubular member 24 can be regarded as connected to the bottom seal upper surface 124.

[0025] 另外,于本实施例中,透光部122、挠性不透光管状件24形成的通道、不透光罩22及其开口222、发光单元20大致成直线设置,发光单元20容易穿过挠性不透光管状件24形成的通道、透光部122而射出键帽12 ;但本发明不以此为限。 [0025] Further, in the present embodiment, the transparent portion 122, the flexible tubular member 24 opaque passage formed without opening 222 and the transparent cover 22, the light emitting unit 20 is disposed substantially in line, the light emitting unit 20 is easily the flexible light transmitting through the channel of the tubular member 24 is not formed, the light-transmitting portion 122 emits the keycap 12; however, the present invention is not limited thereto. 例如,当挠性不透光管状件24内壁具有一定的反射率时,进入挠性不透光管状件24形成的通道的光线LI可通过通道内壁的多次反射而自第二开口端244射出挠性不透光管状件24 ;此时,透光部122、挠性不透光管状件24形成的通道、不透光罩22及其开口222、发光单元20可无需成直线设置。 For example, when the flexible opaque inner wall of the tubular member 24 has a certain reflectivity, the light entering the light transmissive LI flexible tubular member 24 is not formed in the channel by multiple reflections from the inner channel wall and second open end 244 exit the flexible tubular member 24 opaque; in this case, the light-transmitting portion 122, the flexible tubular member 24 is not light transmitting passage is formed, and the opening 22 is not transparent cover 222, without the light emitting unit 20 may be disposed in line. 光线LI穿过透光部122可提供使用者视觉上的指示效果,于本实施例中,透光部122于键帽12顶表面呈圆形轮廓,例如当光线LI穿过透光部122时,即可指示使用者键盘处于字母大写的输入状态。 Light passes through the light transmitting portion LI 122 may provide an indication on the user's visual effect, in the present embodiment, the light-transmitting portion has a circular contour 122 on the surface of the key top 12, for example, when the light passes through the light transmitting portion 122 LI , indicating to the user keyboard input state capitalized. 于实际运用中,透光部122形成的图样可依产品要求而定,不以前述圆形为限,亦可为字体或是其他图案(例如特定标志、符号)字母为限。 In practice, the pattern of the light-transmitting portion 122 is formed to follow the product requirements, not limited to the circular, or other patterns may also be Font (e.g., specific signs, symbols) is limited to letters. 另外,于本实施例中,透光部122为可透光实体,但本发明不以此为限,例如直接于键帽12镂空形成透光部亦可。 Further, in the present embodiment, the light transmitting portion to be light-transmitting entity 122, but the present invention is not limited to, for example, be formed directly on the light transmitting key top portion 12 may also be hollow.
