[0004] 再者,请同步参阅图2,其为图1所示发光键盘的薄膜线路板的立体分解图,下层板141具有由多个银胶线路14111与多个下接点14112所组成的第一电路图案1411,而上层板142具有由多个银胶线路14211与多个上接点14212所组成的第二电路图案1421,又,中层板143具有对应于多个下接点14122与多个上接点14212的接点开孔1431,其中,每一上接点14212与其对应的下接点14112共同形成一薄膜开关144。 [0004] In addition, please refer to FIG. 2 sync, which the glue line 141 having a plurality of silver with a plurality of contacts 14 111 14 112 is composed of a film shown in a perspective exploded view of the illuminated keyboard circuit board, a lower plate of FIG. a circuit pattern 1411, and the upper plate 142 has a plurality of glue line 14211 and a plurality of silver contacts the second circuit pattern consisting of 142,114,212, and, corresponding to the intermediate plate 143 having a plurality of contacts on the plurality of contacts 14122 via openings 143,114,212, wherein each of the contacts corresponding to the upper contact therewith 14212 14112 144 collectively form a membrane switch.

[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穿过其中的通孔145以及通孔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 the 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,藉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会根据弹性体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 based on 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] For the above described first point and a second known point, the key 15 generates a plurality of light emitting Although the effect of conventional illuminated keyboard of formula I through the mating side and the light emitting element 16 light guide plate 12, but the light used inefficient. 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,藉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按键15的移动行程中,故使用者就无法通过下压键帽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 15 is located in the movement stroke of the key, so that the user can not reach the power corresponding to the key top 151 by depressing the membrane switch 144 conduction properties, is to alternate a direct-type light emitting element 16 side and provide a light emitting element beam approach toward the key 15 can not be directly implemented on a particular conventional illuminated keyboard I.

[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,其通过键帽被下压的过程中改变键盘的电路板中的一相对应电容式开关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 has been proposed, which processes the key cap is depressed by a corresponding change in the capacitive keyboard circuit board the switch circuit board field generates an output corresponding to a 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; however, nowadays yet having the light emitting effect is presented capacitive sensing keyboard, so that under low light environment, a user may see the clear key on the keyboard marked capacitive sensing figures and text, thereby causing operational difficulties or visually impaired .
