[0005] 又,支撑板13设置于薄膜线路板14的下方,并具有多个穿孔131、第一固定结构132以及第二固定结构133 ;而每一按键15包括键帽151、弹性体152以及剪刀式连接元件153,且键帽151包括第一键帽固定结构1511以及第二键帽固定结构1512 ;而剪刀式连接元件153包括第一框架1531以及第二框架1532 ;此外,弹性体152位于键帽151与薄膜线路板141之间。 [0005] Further, the support plate 13 is provided below the thin film wiring board 14 and having a plurality of perforations 131, a first fixing structure 132 and second fixing structure 133; and each key 15 comprises a key cap 151, the elastic member 152, and scissors-type connecting member 153, and a first key cap 151 includes a keycap fixing structure 1511 and the second keycap fixing structure 1512; the scissors-type connecting member 153 comprises a first frame and a second frame 1531 1532; In addition, the elastic member 152 is located Cap between 151 and 141 film wiring board.

[0006] 其中,薄膜线路板14具有分别供第一固定结构132以及第二固定结构133穿过其中的透孔145以及透孔146,以供第一框架1531的一端15311可连接于第二固定结构133,且其另一端15312可连接于第一键帽固定结构1511,并供第二框架1532的一端15321可连接于第一固定结构132,且其另一端15322可连接于第二键帽固定结构1512。 [0006] wherein the thin film wiring board 14 are respectively supplied with a first fixing structure 132 and second fixing structure 133 which passes through the through hole 145 and through hole 146 to which one end of a first frame 15311 1531 may be connected to the second fixing structure 133, and the other may be connected to the first end 15312 keycap fixing structure 1511, and one end of which the second frame 153,211,532 may be connected to the first fixing structure 132, and the other end connected to the second keycap 15322 may be secured 1512 structure.

[0007] 当任一按键15被触压而相对于支撑板13往下移动时,剪刀式连接元件153的第一框架1531与第二框架1532由开合状态变更为叠合状态,且往下移动的键帽151会挤压弹性体152使弹性体152抵顶其相对应的上接点14212,进而使其相对应的上接点14212经由相对应的接点开孔1431而接触相对应的下接点14122,借此令相对应的薄膜开关144达成电性导通,以使发光键盘I产生一相对应的按键信号。 [0007] When any button 15 is depressed relative to the support plate 13 moves downward, the first frame scissors-type connecting member 153 of the second frame 1531 and the opening 1532 is changed from engaged state to the stacked state, and down moving keycap 151 will squeeze the elastic body 152 so that the elastic member 152 abuts against its corresponding contacts 14212, and further on it corresponding to the contact hole through the contact 1431 14212 corresponding to the contact point corresponding to the lower 14122 , whereby the film to reach the switch 144 corresponding to the electrical conduction to the light emitting keyboard I generates a corresponding key signal. 而当按键15不再被触压时,键帽151会因应弹性体152的弹性力而相对于支撑板13往上移动,此时第一框架1531以及第二框架1532由叠合状态变更为开合状态,且键帽151会恢复原位。 When no key 15 is depressed, the keycap 151 Hui Yinying the elastic force of the elastic member 152 relative to the support plate 13 is moved upward, while the first frame 1531 and second frame 1532 is changed from the open state superimposed together state, and the key cap 151 will return to its original position. [0008] 再者,侧向式发光元件16设置于导光板12的侧边,用以提供光束射入导光板12。 [0008] Further, the lateral-type light emitting element 16 disposed on the side of the light guide plate 12, for providing a light beam incident on the light guide plate 12. 而导光板12设置于反光板11上,且其下表面具有用以聚集且散射光束的多个导光点121。 And the light guide plate 12 is provided on the reflecting plate 11, and a lower surface having a plurality of light guide points 121 and to collect the scattered light beam. 多个导光点121依对应多个按键15的位置而被设置。 A plurality of light guide 121 by location points corresponding to the plurality of keys 15 is provided. 其中,于光束射入导光板12时,光束得以被扩散至整个导光板12,且多个导光点121会因其为油墨材质的关系而将光束往上及往下散射,往上散射的光束会依序通过支撑板13的多个穿孔131以及薄膜线路板14而投射至多个按键15,而往下散射的光束会再经由反光板11的辅助而使光束向上反射,以使侧向式发光元件16所提供的光束可被完善利用。 Wherein the beam incident on the light guide plate 12, the light beam is diffused throughout the light guide plate 12, and a plurality of light guide points 121 due to their relationship of the ink material and scattering the light beam up and down, up scattered will support beam sequentially through a plurality of perforated plate 131 and the thin film 14 of wiring board 13 is projected to a plurality of keys 15, and then down through the scattered light beam will assist the upward reflected beam reflecting plate 11, so that the side of formula light emitting element 16 may be provided to improve utilization. 如上所述,即可使多个按键15产生发光的效果。 As described above, a plurality of keys 15 to produce light emission results. 惟,现有的发光键盘I具有如下所述的缺点: However, the conventional illuminated keyboard I has disadvantages as described below:

[0009] 一、虽然反光板11可辅助多个导光点121向下散射的光束向上方反射,但现有发光键盘I的反光板11的材质仍可让少许光束穿透,因此一部分由多个导光点121向下散射的光束会穿透反光板11而造成光量的流失。 [0009] First, although the reflecting plate 11 may assist in guiding the plurality of light spots 121 downwardly scattered light is reflected upward, but the material of the conventional illuminated keyboard I reflector 11 may still allow little light penetration, so a portion of a plurality a light guide points 121 will penetrate downwardly scattered beam reflector 11 caused by the loss of light quantity.

[0010] 二、虽然光束射入导光板12时可被扩散至整个导光板12,但由于距离侧向式发光元件16较近的导光点121已将部分光束反射出导光板12外,使得导光板12中距离侧向式发光元件16较远的区域的光量不如距离侧向式发光元件16较近的区域来得充足。 [0010] Second, although the light beam incident on the light guide plate can be diffused throughout the light guide plate 12:12, but the close distance side light-emitting element 16 has the light guide portion 121 spot beams reflected out of the light guide plate 12, such that the light guide plate 12 from the side of the target area light emitting element 16 is more distant enough from the inferior region lateral type light emitting element 16 closer.

[0011] 三、由于剪刀式连接元件153的运作行程较长,故发光键盘I必须要具有足够的空间才能够使剪刀式连接元件153正常运作,然而却因此无法有效的缩减发光键盘I的厚度,以至于无法满足现今电子产品朝向轻、薄、短小发展的外型诉求。 [0011] Third, since the long operating stroke scissors-type connecting member 153, so the light emitting keyboard I must have enough space to be able to make the scissors-type connecting member 153 normal operation, yet not so effectively reduced the thickness of the luminescent keyboard I that it can not meet today's electronic products toward light, thin, short appearance demands of development.

[0012] 针对上述第一点以及第二点的说明可知,虽然现有发光键盘I是透过侧向式发光元件16以及导光板12的配合而使多个按键15产生发光的效果,但光使用效率不佳。 [0012] In view of the above described first point and a second point known, although the conventional illuminated keyboard I is the effect of a plurality of keys 15 with the generated light emission side through the light emitting element 16 and the light guide plate 12, but the light poor efficiency. 基此,在如何改善光使用效率的思维下,尝试以直下式发光元件替代侧向式发光元件16,并使直下式发光元件设置于按键15的下方,才能直接对按键15提供光束,借此获得较佳的光使用效率;然而,在这样的作法中,直下式发光元件是位于弹性体152的下方,会阻碍弹性体152被挤压后的移动行程,故使用者就无法借由下压键帽151而使相对应的薄膜开关144达成电性导通,是以,以直下式发光元件替代侧向式发光元件16并直接朝按键15提供光束的做法无法具体实施在现有的发光键盘I上。 By virtue of this, how to improve the efficiency in using light mind, attempts to replace a direct-type light emitting element side light-emitting element 16, and a direct type light emitting element is disposed below the button 15, in order to provide a light beam directly on the key 15, whereby to get a better light use efficiency; however, such a practice, the direct type light emitting element is located below the elastic body 152, the movement stroke will hinder the elastic body 152 is compressed, so that the user can not take the pressure of the Cap 151 of the membrane switch 144 corresponding to achieve electrical conduction, it is to replace a direct-type light emitting element side toward the light-emitting element 16 and the beam 15 provides a key approach can not be implemented directly in existing DETAILED illuminated keyboard I on.

[0013] 再者,有鉴于上述第三点所述的缺陷,现已有一种电容感应式键盘被提出,其是借由键帽被下压的过程中改变键盘的电路板的电场而使电路板产生输出一相对应的按键信号;其中,由于电容感应式键盘不一定要使用剪刀式连接元件等相关元件,使得电容感应式键盘的整体厚度可有效减少;然而,现今尚未有具发光效果的电容感应式键盘被提出,故在光线较弱的环境下,使用者可能看不清楚电容感应式键盘上的按键所标示的数字以及文字,因而造成作业困难或视力受损。 [0013] Moreover, the third point of view of the defects, is now a capacitive sensing keyboard is proposed by means of which the electric field during the keycap is depressed to change the keyboard circuit board a plate producing an output corresponding to the key signal; wherein, due to the capacitive sensing keyboard not required to use elements related scissors-type connecting element and the like, such that the overall thickness of the capacitive sensing keyboard may be effectively reduced; today, however, there has not been a light emitting effect capacitive sensing keyboard is raised, it is in low light environment, a user may see the clear key on the keyboard marked capacitive sensing figures and text, thereby causing operational difficulties or impaired vision.

[0125] 一般来说,透光区域2513设计于键帽251的角落,然而,由于透光弹性体27与键帽251的距离过短,故穿过透光弹性体27后的光束无法有效地折射至位于键帽251角落的透光区域2513,也就是说,大部分的光束是投射至键帽251的中间区域,因此光的使用效率较为不佳。 [0125] In general, the light-transmitting region 2513 designed to corner keycap 251, however, since the transparent elastomer 27 keycap distance 251 is too short, it is not effectively passing through the light beam 27 after the transparent elastomer key cap 251 to the corner located in the refractive light transmitting region 2513, that is to say, most of the beams are projected to the intermediate region 251 of the key top, so more light use efficiency is poor.

[0126] 基此,于本较佳实施例中,透光弹性体27可为一透镜体(如凸凹透镜,但不以此为限),也就是说,借由特别设计透光弹性体27的形状而使得透光弹性体27具有透镜功能,以改变穿过透光弹性体27的光束的传输路径,即使穿过透光弹性体27的光束能够朝着键帽251的透光区域2513的方向行径。 [0126] By virtue of this, in this preferred embodiment, the lens body 27 may be a transparent elastomer (e.g., meniscus lens, but not limited to) embodiment, i.e., by means of specially designed transparent elastomer 27 shape such that the light-transmitting elastic body 27 having a lens function to change the transmission path of the light beam passes through the transparent elastomer 27, even when the light beam passes through the transparent elastomer toward the light-transmissive region 27 can keycap 251 2513 direction acts. 当然,上述仅为使穿过透光弹性体27的光束扩散至键帽251的透光区域2513的一种实施方式,本领域普通技术人员可依据实际应用需求而进行任何均等的变化设计。 Of course, this is only the light beam passes through the transparent elastomer 27 is diffused to the keycap one embodiment of the transmissive region 251 of 2513, those of ordinary skill in the art may be any according to the actual design of a uniform change in application requirements.

[0127] 举例来说,请参阅图6,其为使穿过透光弹性体的光束能够扩散至键帽的透光区域的一较佳实施概念示意图。 [0127] For example, please refer to FIG. 6, which is a light beam passes through the transparent elastomer can be diffused to the conceptual diagram of a preferred embodiment of the light-transmitting region keycap. 图6示意了透光弹性体27上还设置有透镜体271,因此光束于穿过透光弹性体27后会接着穿过透镜体271,借此改变光束的传输路径,也就是说,使穿过透镜体271的光束能够朝着键帽的透光区域的方向行径。 FIG 6 illustrates a light-transmissive elastic body 27 is also provided with a lens 271, after passing through the light beam 27 then passes through the transparent elastomer will lens body 271, thereby changing the transmission path of the beam, i.e. so that wear beam through the lens body 271 can act in the direction of the light-transmitting region keycap.

[0128] 再举例来说,请参阅图7,其为使穿过透光弹性体的光束能够扩散至键帽的透光区域的另一较佳实施概念示意图。 [0128] As another example, see Figure 7, which is a light beam passes through the transparent elastomer can be diffused to the conceptual diagram of another preferred embodiment of the light-transmitting region of the keycap. 图7示意了透光弹性体27上具有多个微结构272,因此光束于穿过多个微结构272后会改变行径的方向,也就是说,使穿过微结构272的光束能够朝着键帽的透光区域的方向行径。 Figure 7 illustrates a microstructure 272 having a plurality of transparent elastomer 27, the light beam passing through the direction change after act 272 a plurality of microstructures, i.e., the beam passes through the microstructure capable of moving key 272 direction acts translucent area of ​​the cap. 补充说明的是,图7所示的微结构272为V形切割(V-CUT)结构,但不以此为限,如微结构亦可为咬花图案结构273形成于透光弹性体27的表面上,其如图8所示。 It is added that, the microstructure shown in FIG. 7 is a V-cut 272 (V-CUT) and is not limited to, the structure may also be micro-texturing pattern structure 273 is formed on the transparent elastomer 27 an upper surface, which as shown in FIG. 惟,上述使穿过透光弹性体27的光束能够扩散至键帽251的透光区域2513的各种实施例为例说明之用,并非用以限制本发明的范围。 However, the above-described light beam passing through the light-transmitting elastic body 27 can be diffused to the keycap various light-transmissive region 2513 Example 251 as an example only and is not intended to limit the scope of the invention.
