五、新型說明： 【新型所屬之技術領域】 [0001] 本創作係關於一種按鍵面板，尤其涉及一種電子裝置上 用於輸入的按鍵面板。 【先前技術】 [0002] 隨著資訊科技時代的到來，再加上通信網路技術的進步 下，移動電話已經成為目前最常見的通訊工具之一，習 知的移動電話都開始朝著輕、薄、短、小的體積而製造 ，由此縮減移動電話的尺寸和重量；在移動電話的製造 中，除了内部的積體電路的體積縮小之外，安裝在移動 電話表面的按鍵面板的體積也要相對縮減，這樣才能夠 達到輕、薄、短、小的目的。 [0003] 習知移動電話的按鍵面板大多數係採用類似美國第 US2007/0205986A1號專利申請所揭示的結構。該專利 申請的金屬按鍵面板10a具有彈性層la，彈性層la的一側 具有多個凸體11a，而對應凸體11a的彈性層la的另一側 la配置多個金屬按鍵2a。金屬按鍵2a上具有與其圖案相 對應的鏤空部21a，在鏤空部21a填入具有透光性的樹脂 層22a。當金屬面板10a配置在電子裝置的座體20a時， 金屬按鍵面板10a位於電路模組30a上，電路模組30a具 有印刷電路板30a，電路板31a上具有多個不動的接觸點 32a，在電路板3la上配置金屬片33a，金屬片33a上具有 多個圓弧球面的彈片331a，彈片331a與每個接觸點32a 相對應，而彈片331 a的另一側則與凸體11a對應。當金屬 按鍵2a被按下時，使得凸體11a壓在彈片331a的表面上 表單编號A0101 第3頁/共16頁 M376083 。彈片331a變形並與接觸點32a接觸從而產生信號輸出。 而且，在點亮背景照明時，該背景照明的光線可以穿過 金屬按鍵2a的樹脂層22a，讓使用者可以清楚的看見每個 按鍵的位置。 [0004] 雖然上述用於安裝在體積小的電子裝置上的金屬按鍵面 板10a已經具有朝輕、薄、短、小的製作趨勢，然，在製 作上必須將金屬按鍵2a上鏤空部21 a逐一的填入樹脂層 22a後，再將金屬按鍵2a—個一個精確的粘附在彈性層la 的一側。如此導致較費時、費工、不容易製作。此外， 在金屬按鍵面板10a組合後，與座體20a結合時，該金屬 按鍵2a週邊處與座體20a之間有缝隙。該縫隙容易使得外 部的灰塵囤積或者導致水滲入，造成按鍵按靨手感不良 ，或者造成短路。 [0005] 鑒於此，實有必要設計一種新的按鍵面板來解決上述問 題。 【新型内容】 [0006] 本創作的主要目的係提供一種結構簡單、易於製造、圖 案清晰明亮、並且具有防灰塵囤積和防水滲入的按鍵面 板。 [0007] 本創作是這樣解決上述目的的：一種按鍵面板，供配置 於電子裝置表面上，主要包括一個由透明或者半透明材 料製成的透光塑膠層，透光塑膠層的一側設有微孔層， 透光塑膠層與微孔層相對的一側設有圖案層，其中，所 述微孔層上設有複數貫穿於微孔層設置的微孔，所述圖 表單編號A0101 第4頁/共16頁 案層貫穿設有複數鏤空部。 [0008] 與習知技術相比較，本創作具有以下優點：結構簡單、 易於製造、圖案清晰明亮、並且具有防灰塵囤積和防水 滲入的效果。 【實施方式】 [0009] 下面，將結合附圖對本創作作進一步詳細描述。 [0010] 請參閱第一圖至第三圖所示，本按鍵面板100主要包括透 光塑膠層1、通過喷塗或者印刷附著於透光塑膠層1 一側 的微孔層2、通過印刷方式附著於透光塑膠層1另一側的 圖案層3，以及一個照明模組4。V. New description: [New technical field] [0001] The present invention relates to a key panel, and more particularly to a key panel for input on an electronic device. [Prior Art] [0002] With the advent of the information technology era and the advancement of communication network technology, mobile phones have become one of the most common communication tools, and the known mobile phones are beginning to move toward light. Thin, short, and small in size, thereby reducing the size and weight of the mobile phone; in the manufacture of mobile phones, in addition to the volume reduction of the internal integrated circuit, the volume of the button panel mounted on the surface of the mobile phone is also To be relatively reduced, it is possible to achieve light, thin, short, and small goals. [0003] The majority of the key panels of conventional mobile telephones are constructed using a structure similar to that disclosed in US Patent Application Publication No. US-A-2007/0205986A1. The metal button panel 10a of this patent application has an elastic layer 1a having a plurality of convex bodies 11a on one side and a plurality of metal buttons 2a on the other side la of the elastic layer 1a corresponding to the convex body 11a. The metal button 2a has a hollow portion 21a corresponding to the pattern, and the hollow portion 21a is filled with a light-transmissive resin layer 22a. When the metal panel 10a is disposed on the base 20a of the electronic device, the metal button panel 10a is located on the circuit module 30a, and the circuit module 30a has a printed circuit board 30a having a plurality of fixed contact points 32a on the circuit board 31a. A metal piece 33a is disposed on the plate 3a. The metal piece 33a has a plurality of circular arc-shaped elastic pieces 331a. The elastic piece 331a corresponds to each contact point 32a, and the other side of the elastic piece 331a corresponds to the convex body 11a. When the metal button 2a is pressed, the projection 11a is pressed against the surface of the elastic piece 331a. Form No. A0101 Page 3 of 16 M376083. The elastic piece 331a is deformed and brought into contact with the contact point 32a to generate a signal output. Moreover, when the background illumination is illuminated, the backlight of the background illumination can pass through the resin layer 22a of the metal button 2a, so that the user can clearly see the position of each button. [0004] Although the metal button panel 10a for mounting on a small-sized electronic device has a tendency to be light, thin, short, and small, the hollow portion 21a of the metal button 2a must be made one by one. After the resin layer 22a is filled in, the metal buttons 2a are adhered to one side of the elastic layer la one by one. This leads to more time-consuming, labor-intensive, and not easy to make. Further, when the metal key panel 10a is combined, when it is coupled to the base body 20a, there is a gap between the periphery of the metal button 2a and the seat body 20a. This gap is liable to cause external dust to accumulate or cause water to infiltrate, resulting in poor button feel or short circuit. [0005] In view of this, it is necessary to design a new key panel to solve the above problem. [New Content] [0006] The main purpose of this creation is to provide a button panel that is simple in structure, easy to manufacture, clear and bright in pattern, and resistant to dust accumulation and water infiltration. [0007] The present invention solves the above-mentioned purposes: a key panel is disposed on a surface of an electronic device, and mainly includes a light transmissive plastic layer made of a transparent or translucent material, and one side of the transparent plastic layer is disposed. a microporous layer, a side of the transparent plastic layer opposite to the microporous layer is provided with a pattern layer, wherein the microporous layer is provided with a plurality of micropores arranged through the microporous layer, the drawing form number A0101 is 4 The page/16 pages are provided with a plurality of hollows.
