When the keycap is pressed, the elastic layer is deformed to store an elastic potential energy, so that when the external force is released, the elastic position can be released to drive the keycap back to the initial position. However, it is difficult to judge the degree of merit between the elastomer of the elastomer layer and the substrate.

請參照第1A及1B圖,第1A圖繪示依照本發明一實施例之彈性體層設置於鍵帽150、支撐機構160及底板170中的剖視圖(為避免圖式過於複雜,底板170、鍵帽150及支撐機構160均以虛線表示),第1B圖繪示第1A圖彈性體層的底視圖。彈性體層100至少包括透光基板110、彈性體120、接著劑130。其中接著劑130可為:(1)接著劑130材料透光,其中參雜有指示劑140,或(2)接著劑130材料本身不透光,接著劑本身就有顏色。Referring to FIGS. 1A and 1B , FIG. 1A is a cross-sectional view showing an elastic layer disposed in the keycap 150 , the support mechanism 160 , and the bottom plate 170 according to an embodiment of the invention (to avoid the complexity of the drawing, the bottom plate 170 and the key cap). 150 and support mechanism 160 are both shown by dashed lines), and FIG. 1B is a bottom view of the elastomer layer of FIG. 1A. The elastomer layer 100 includes at least a light transmissive substrate 110, an elastomer 120, and an adhesive 130. The adhesive 130 may be: (1) the adhesive 130 material is light transmissive, wherein the indicator 140 is mixed, or (2) the adhesive 130 material itself is opaque, and the adhesive itself has a color.

透光基板110例如是麥拉片(mylar)或薄膜電路板。透光基板110例如是一薄膜開關層。舉例來說,透光基板110可包括第一薄膜111、第二薄膜112、間隔層113、第一導電體114及第二導電體115。間隔層113位於第一薄膜111與第二薄膜112之間,且具有一開孔113a。第一導電體114形成於第一薄膜111上,而第二導電體115形成於第二薄膜112上,且第一導電體114與第二導電體115相對配置。第一導電體114與第二導電體115的位置對應開孔113a。當鍵帽150受到按壓時會帶動彈性體120形變,形變的彈性體120施壓於透光基板110,使第一導電體114與第二導電體115透過開孔113a電性連接,並透過所連接的電路輸出一按鍵訊號。支撐機構160設置於鍵帽150與透光基板110之間,可活動地連接鍵帽150與透光基板110,使鍵帽150相對於透光基板110(亦即相對 於彈性體層100)可上下活動。The light-transmitting substrate 110 is, for example, a mylar or a thin film circuit board. The light transmissive substrate 110 is, for example, a membrane switch layer. For example, the transparent substrate 110 may include a first film 111, a second film 112, a spacer layer 113, a first electrical conductor 114, and a second electrical conductor 115. The spacer layer 113 is located between the first film 111 and the second film 112 and has an opening 113a. The first electrical conductor 114 is formed on the first film 111, and the second electrical conductor 115 is formed on the second film 112, and the first electrical conductor 114 is disposed opposite to the second electrical conductor 115. The positions of the first electrical conductor 114 and the second electrical conductor 115 correspond to the opening 113a. When the key cap 150 is pressed, the elastic body 120 is deformed, and the deformed elastic body 120 is pressed against the transparent substrate 110 to electrically connect the first electrical conductor 114 and the second electrical conductor 115 through the opening 113a. The connected circuit outputs a button signal. The supporting mechanism 160 is disposed between the keycap 150 and the transparent substrate 110, and movably connects the keycap 150 and the transparent substrate 110 to make the keycap 150 relative to the transparent substrate 110 (ie, opposite The elastomer layer 100) can move up and down.

透光基板110具有相對之透光基板上表面110u與透光基板下表面110b。由於組成透光基板110的第一薄膜111、第二薄膜112、間隔層113均可透光,故光線可穿透透光基板,在上表面110u及下表面110b間自由地行進。The transparent substrate 110 has an opposite transparent substrate upper surface 110u and a transparent substrate lower surface 110b. Since the first film 111, the second film 112, and the spacer layer 113 constituting the transparent substrate 110 can transmit light, the light can penetrate the transparent substrate and travel freely between the upper surface 110u and the lower surface 110b.

彈性體120設置於透光基板110上方。彈性體120具有一彈性體下表面120b,彈性體下表面120b具有一預設黏著區R1。本實施例之彈性體120係由透光材料所形成,如此上方光源的光線可穿透彈性體120而照射穿過透光接著劑130,然後光線再向下繼續行進穿過透光基板110而被觀察到。The elastic body 120 is disposed above the light transmissive substrate 110. The elastomer 120 has an elastomeric lower surface 120b, and the elastomer lower surface 120b has a predetermined adhesive region R1. The elastic body 120 of the present embodiment is formed of a light transmissive material, such that the light of the upper light source can penetrate the elastic body 120 and illuminate through the transparent adhesive 130, and then the light continues to travel downward through the transparent substrate 110. be observed.

只要透光接著劑130可透光即可,本發明實施例不限定透光接著劑130的透光率。一實施例中,透光接著劑130的透光率可介於40%至100%之間。在此透光率範圍下,光線可穿透透光接著劑130而照射到指示劑140,使指示劑140激發出具有特定波長的光線。此外,在上述透光率範圍下,指示劑140所激發出的具有特定波長的光線足可顯示出透光接著劑130的塗佈區域,以便於觀察透光接著劑130的塗佈狀況。As long as the light-transmitting adhesive 130 can transmit light, the embodiment of the present invention does not limit the light transmittance of the light-transmitting adhesive 130. In one embodiment, the light transmissive adhesive 130 may have a light transmittance of between 40% and 100%. At this range of light transmittance, light can penetrate the light-transmitting adhesive 130 to illuminate the indicator 140, causing the indicator 140 to excite light having a particular wavelength. In addition, under the above light transmittance range, the light having a specific wavelength excited by the indicator 140 can show the coated area of the light-transmitting adhesive 130 in order to observe the coating condition of the light-transmitting adhesive 130.

透光接著劑130形成於彈性體下表面120b與透光基板110之間。一實施例中,透光接著劑130可採用網版印刷形成於透光基板110上,然後彈性體120再黏合於透光接著劑130上,以固定彈性體120與透光基板110之間的相對位置。透光接著劑 130在透光基板110上佔據一塗佈區域R2。塗佈區域R2的面積可大於或等於預設黏著區R1的面積,且塗佈區域R2與預設黏著區R1至少部分重疊。當整個預設黏著區R1完全重疊於塗佈區域R2時,表示彈性體120與透光基板110的接著狀況優良;當預設黏著區R1與塗佈區域R2未重疊的部分超過一定面積時,表示部分彈性體下表面120b未黏合於透光接著劑130,如此可能導致彈性體120與透光基板110的接著性不足或不符預期。The light transmissive adhesive 130 is formed between the lower surface 120b of the elastomer and the transparent substrate 110. In one embodiment, the light-transmissive adhesive 130 can be formed on the transparent substrate 110 by screen printing, and then the elastic body 120 is adhered to the transparent adhesive 130 to fix the gap between the elastic body 120 and the transparent substrate 110. relative position. Light transmissive adhesive 130 occupies a coating region R2 on the light-transmitting substrate 110. The area of the coating region R2 may be greater than or equal to the area of the predetermined adhesive region R1, and the coating region R2 at least partially overlaps the predetermined adhesive region R1. When the entire predetermined adhesive region R1 is completely overlapped with the coating region R2, it indicates that the elastic body 120 and the transparent substrate 110 are in an excellent condition; when the portion where the predetermined adhesive region R1 and the coating region R2 do not overlap exceeds a certain area, It is indicated that the partial elastic lower surface 120b is not bonded to the light-transmitting adhesive 130, which may result in insufficient or undesired adhesion of the elastic body 120 to the transparent substrate 110.

指示劑140摻雜於透光接著劑130內。透過指示劑140,可觀察彈性體120與透光基板110的接著優劣程度。詳細來說,由於本實施例之透光基板110、彈性體120及透光接著劑130皆具有透光性,可使光線穿透彈性體120及透光接著劑130,而照射到指示劑140。指示劑140係一具有特定波長的螢光劑。當一具有該特定波長的光線照射到指示劑140時,指示劑140可發出一預定波長光穿透透光基板110,使預定波長光於透光基板下表面110b顯示出塗佈區域R2。藉由顯示出的塗佈區域R2,可觀察塗佈區域R2與預設黏著區R1的重疊關係,進而觀察彈性體120與透光基板110的接著優劣程度。上述特定波長可以是屬於不可見光的波段的其中一波長,如此,當其它波段的光線照射到指示劑140時,可避免指示劑140發出預定波長光而去影響鍵帽150的圖案顯示(當鍵帽10係光穿透型鍵帽時)。The indicator 140 is doped in the light transmissive adhesive 130. Through the indicator 140, the degree of pros and cons of the elastomer 120 and the transparent substrate 110 can be observed. In detail, since the light-transmitting substrate 110, the elastic body 120, and the light-transmitting adhesive 130 of the present embodiment are all translucent, light can penetrate the elastic body 120 and the light-transmitting adhesive 130 to be irradiated to the indicator 140. . The indicator 140 is a phosphor having a specific wavelength. When a light having the specific wavelength is irradiated to the indicator 140, the indicator 140 emits a predetermined wavelength of light to penetrate the transparent substrate 110, so that the predetermined wavelength of light shows the coated region R2 on the transparent substrate lower surface 110b. By displaying the coated region R2, the overlapping relationship between the coated region R2 and the predetermined adhesive region R1 can be observed, and the degree of the subsequent advantages of the elastic body 120 and the transparent substrate 110 can be observed. The specific wavelength may be one of wavelengths of the invisible light band, such that when light of other wavelength bands is irradiated to the indicator 140, the indicator 140 may be prevented from emitting a predetermined wavelength of light to affect the pattern display of the keycap 150 (when the key When the cap 10 is a light-transmitting type keycap).

另一實施例中,指示劑140可以是染料。在此設計 下,只要光線是可見光,就能顯示出染料的分佈,藉此顯示出塗佈區域R2的分佈,進而觀察塗佈區域R2與預設黏著區R1的重疊關係。如此,可觀察出彈性體120與透光基板110的接著優劣程度。In another embodiment, the indicator 140 can be a dye. Designed here Next, as long as the light is visible light, the distribution of the dye can be displayed, thereby showing the distribution of the coated region R2, and further observing the overlapping relationship between the coated region R2 and the predetermined adhesive region R1. Thus, the degree of superiority and inferiority of the elastic body 120 and the light-transmitting substrate 110 can be observed.

如第1A圖所示,彈性體120包括相連接之蓋帽121及環形接腳122。透光接著劑130黏合環形接腳122與透光基板110。蓋帽121具有至少一逃氣孔121a連通彈性體120內部與外界,以使彈性體120內部的空氣透過逃氣孔121a逃逸至彈性體120外。如此,可避免彈性體120的彈性受到空氣的影響而降低。另一實施例中,逃氣孔121a亦可貫穿環形接腳122。如第1B圖所示,塗佈區域R2呈封閉環形,相較於開放環形,呈封閉環形之透光接著劑130可涵蓋到較多部分的彈性體下表面120b。As shown in FIG. 1A, the elastomer 120 includes a connecting cap 121 and an annular pin 122. The light-transmitting adhesive 130 bonds the annular pin 122 and the transparent substrate 110. The cap 121 has at least one escape hole 121a communicating with the inside of the elastic body 120 and the outside, so that the air inside the elastic body 120 escapes to the outside of the elastic body 120 through the escape hole 121a. In this way, it is possible to prevent the elasticity of the elastic body 120 from being lowered by the influence of the air. In another embodiment, the escape hole 121a may also penetrate the annular pin 122. As shown in FIG. 1B, the coated region R2 has a closed annular shape, and the closed-loop transparent adhesive 130 can cover a greater portion of the elastomeric lower surface 120b than the open annular shape.

請參照第2A及2B圖,第2A圖繪示依照本發明另一實施例之彈性體層的剖視圖,第2B圖繪示第2A圖的底視圖,其中第2A圖係第2B圖沿方向2A-2A’的剖視圖。彈性體層200包括透光基板110、彈性體120、透光接著劑130及指示劑140。2A and 2B, FIG. 2A is a cross-sectional view of an elastomer layer according to another embodiment of the present invention, and FIG. 2B is a bottom view of FIG. 2A, wherein FIG. 2A is a second view of FIG. A cross-sectional view of 2A'. The elastomer layer 200 includes a light transmissive substrate 110, an elastomer 120, a light transmissive adhesive 130, and an indicator 140.

與上述彈性體120不同的是,本實施例之彈性體120於透光基板110上投影具有一投影中心點C1,塗佈區域R2呈數條線段R21,此些線段R21實質對稱地分布於投影中心點C1四周。舉例來說,線段R21可以是弧形,且此些線段R21彼此間隔。數段線段R21之間的間隔A1可作為逃氣孔,使彈性體120內部的 空氣透過數段線段R21之間的間隔A1逃逸至彈性體120外,以避免彈性體120的彈性受到空氣的影響而降低。在此設計下,本實施例之彈性體120可選擇性省略逃氣孔121a。另一實施例中,線段R21不限於弧線,亦可為直線或弧形以外的曲線。Different from the above-mentioned elastic body 120, the elastic body 120 of the present embodiment has a projection center point C1 projected on the transparent substrate 110, and the coating area R2 has a plurality of line segments R21, and the line segments R21 are substantially symmetrically distributed on the projection. The center point is around C1. For example, the line segment R21 may be curved, and the line segments R21 are spaced apart from each other.

如第3B圖所示,設置彈性體層100於光源11與影像擷取裝置12之間。As shown in FIG. 3B, an elastomer layer 100 is disposed between the light source 11 and the image capturing device 12.

如第3B圖所示,光源11發射光線L1穿透彈性體120及透光接著劑130而照射到摻雜於透光接著劑130內的指示劑140。由於光線L1具有特定波長,且指示劑140係具有該特定波長的螢光劑,使當光線L1照射指示劑140後,指示劑140激發出一預定波長光穿透透光基板110之透光基板下表面110b。As shown in FIG. 3B, the light source 11 emits light L1 through the elastic body 120 and the light-transmitting adhesive 130 to be irradiated to the indicator 140 doped in the light-transmitting adhesive 130. Since the light ray L1 has a specific wavelength, and the indicator 140 has the fluorescent agent of the specific wavelength, when the light ray L1 illuminates the indicator 140, the indicator 140 excites a transparent substrate of a predetermined wavelength of light penetrating the transparent substrate 110.

如第3B圖所示,比較單元13可分析塗佈區域R2(第1B圖)的影像,並比較塗佈區域R2與預設黏著區R1(第1B圖)的差異,以判斷塗佈區域R2是否合格。例如,比較單元13分析塗佈區域R2與預設黏著區R1的面積差異,當二者的面積差異低於一預定門檻時,表示彈性體120與透光基板110的接著性係足夠的,則比較單元13輸出一彈性體層檢驗合格訊號S1;反之,則比較單元13輸出一彈性體層檢驗不合格訊號S2。As shown in FIG. 3B, the comparison unit 13 can analyze the image of the coated region R2 (Fig. 1B) and compare the difference between the coated region R2 and the predetermined adhesive region R1 (Fig. 1B) to determine the coated region R2. Eligibility. For example, the comparison unit 13 analyzes the difference in area between the coated region R2 and the predetermined adhesive region R1. When the difference in area between the two is lower than a predetermined threshold, it indicates that the adhesion between the elastic body 120 and the transparent substrate 110 is sufficient. The comparison unit 13 outputs an elastomer layer inspection pass signal S1; otherwise, the comparison unit 13 outputs an elastomer layer inspection failure signal S2.

指示單元14例如是聲音輸出器或顯示器,當比較單元13輸出彈性體層檢驗合格訊號S1,指示單元14輸出第一聲音或第一影像;當比較單元13輸出彈性體層檢驗不合格訊號S2,指示單元14輸出一不同於第一聲音的第二聲音或第二影像。The indicating unit 14 is, for example, a sound output device or a display. When the comparing unit 13 outputs the elastomer layer verification pass signal S1, the indicating unit 14 outputs the first sound or the first image; when the comparing unit 13 outputs the elastomer layer check failure signal S2, the indicating unit 14 outputs a second sound or a second image different from the first sound.
