In general, a thin keyboard of a notebook computer is composed of a plurality of buttons, and to simplify the illustration, only one of the buttons is illustrated in the figure for illustration. Referring to the drawing, the notebook thin keyboard 1 〇〇 includes a plurality of buttons 〇, and the circuit board 120 ′, which causes the circuit board 12 〇 to have a plurality of switch orders =, and each of the buttons 110 corresponds to the switch unit 122. Each of the button members 支撑, the support member 114, and the elastic member 116. The singular element is disposed between the keycap 112 and the switch unit 122 by a common _ key =, usually the disk 1 〇", and the element (4) is detached, and the brackets 114a, 114b of the shackle I surround the elastic member 5 1321286 0950283 21979twf. The doc/n 116_ is formed by cross-linking so that the lower surface of the keycap 112 is substantially flat on the upper surface of the circuit board 120. Further, the elastic member 116 is usually made of a rubber material and has a The cover body (10) and a protruding portion, wherein the protruding portion 116b is located in the cover body 116a. When the user presses the seat cap 112, the bracket U4a, 114b rotates along the pivotal portion thereof, and at the same time, the cover body 116a Elastic deformation will occur to cause the key towel 112 to translate toward the circuit board (10) to make the protrusion 116b contact and activate the corresponding switch unit 122. To meet the requirements of the notebook computer for light, thin, short and small The components in the notebook are designed to be thinner. In addition, the overall thickness τ of the notebook thin keyboard 1()() is about 4.5 mm' and under the current architecture, The thickness τ is not (4) reduced, which in turn reduces the overall thickness of the notebook computer. [Inventive content] The purpose of the invention is to provide a thin keyboard with a portable computer, and to reduce the thickness of the thin keyboard. The thin keyboard of the Lei type is turned over to the portable computer, and the package is touched. The control board and the partition plate. The circuit board has a plurality of switch units, the door. The early and the 1^ opening are arranged in the three parts of the touch part = _ on the upper surface of the embossed board and corresponding thereto ίThe upper surface and the lower surface of the board have a plurality of ribs respectively _ ° These ribs protrude from the money hole towel to distinguish each of the 6 0950283 21979twf.doc/n touch two: 1 bulging respectively Corresponding to the switch of the circuit board, when one of the touch parts is pressed, the touch part is adapted to activate the corresponding unit through the protrusion on the partition. i. The preferred embodiment of the present invention For example, the thin keyboard of the embodiment is a metal thin film button (Metal D_). According to a thin keyboard according to a preferred embodiment of the present invention, the circuit board comprises a printed circuit board (Primed Circuit Board, PCB). a thin keyboard according to a preferred embodiment of the invention, The circuit board comprises a flexible printed circuit (FPC). According to a thin keyboard according to a preferred embodiment of the present invention, the touch panel is composed of a transparent plastic film. The touch panel and the spacer used in the thin keyboard are thin, and therefore, the thin keyboard of the present invention has a thin overall thickness. To make the above and other objects, features and advantages of the present invention more apparent, the following DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments, together with the drawings, are described in detail below. 2 is a top view of a thin keyboard according to an embodiment of the present invention, and FIG. 3 is a schematic structural view of the thin keyboard of FIG. 2, and FIG. 4 is an exploded view of FIG. Referring to FIG. 2 to FIG. 4, the thin keyboard 200 is adapted to be assembled on a portable computer, and includes a circuit board 210, a touch panel 220, and a spacer .230. In this embodiment, the portable computer is, for example, a notebook computer, 1321286 0950283 21979twf.doc/n, and the thin keyboard 2〇0 is, for example, a thin keyboard of a notebook computer, and the portable electronic device can be a personal one. The present invention does not impose any limitation on the circuit board 210. The circuit board 210 has a plurality of switch units, and the touch panel has a plurality of touch portions 222 and a plurality of openings. Hole 224. These touch portion milks correspond to the switch units 212, and the openings (10) are configured
些觸控部222之間’其中在本實施例+，觸控部222上可 以被貼上按鍵符號。Between the touch portions 222, in the embodiment +, the touch portion 222 can be pasted with a button symbol.
隔板230具有相野之上表面232以及下表面234，且 上表面232貼附於觸控板22〇，而下表面234朝向電路板 210。隔板230之上表面232與下表面234分別具有多數個 凸肋236以及多數個凸出部238。這些凸肋236分別突出 於逆些開孔224中’以區隔各個觸控部222，使得使用者 ^按壓按鍵時，可以利用觸感來區隔出每-個按鍵。此外， 廷些凸出部238分別對應於電路板21〇上之這些開關單元 212。虽其中一觸控部222被按壓時，觸控部222適於透過 隔板230上之凸出部238啟動對應之開關單元212。 更詳細而言，當觸控部222被按壓時，觸控部222與 隔板230會產生彈性變形，以使隔板23〇上之凸出部238 朝向對應之開關單元212移動，進而接觸開關單元212。 然後’開關單元212會受到凸出部238之壓迫而產生彈性 變形，以使開關單元212之電極會與電路板210之電極接 觸而形成導通。 在本實施例中’電路板21〇例如是印刷電路板或可撓 8 1321286 0950283 21979twf.doc/n 性印刷電路板’而這些開關單元212例如是金屬薄膜按 鍵。在本實施例中，隔板230為一種緩衝材，其材質可為 橡膠。在本實施例中，觸控板220例如是由一印刷有字^ 之透明塑膠薄膜（PC film)所組成，且觸控板220上的這 些觸控部222是利用切割方式來劃分出的，且這些觸控部 222的分布位置可依照標準鍵盤之按鍵位置來設計。The spacer 230 has a phase upper surface 232 and a lower surface 234, and the upper surface 232 is attached to the touch panel 22A, and the lower surface 234 faces the circuit board 210. The upper surface 232 and the lower surface 234 of the spacer 230 have a plurality of ribs 236 and a plurality of projections 238, respectively. The ribs 236 protrude from the opposite openings 224 to separate the respective touch portions 222, so that when the user presses the button, the touch can be used to distinguish each button. In addition, the projections 238 correspond to the switching units 212 on the circuit board 21, respectively. When one of the touch portions 222 is pressed, the touch portion 222 is adapted to activate the corresponding switch unit 212 through the protrusion 238 on the spacer 230. In more detail, when the touch portion 222 is pressed, the touch portion 222 and the partition plate 230 are elastically deformed to move the protruding portion 238 of the partition plate 23 toward the corresponding switch unit 212, thereby contacting the switch. Unit 212. Then, the switch unit 212 is elastically deformed by the pressing of the projection 238, so that the electrodes of the switch unit 212 come into contact with the electrodes of the circuit board 210 to form a conduction. In the present embodiment, the circuit board 21 is, for example, a printed circuit board or a flexible printed circuit board, and these switching units 212 are, for example, metal thin film buttons. In the present embodiment, the spacer 230 is a cushioning material which may be made of rubber. In this embodiment, the touch panel 220 is composed of a transparent plastic film (PC film) printed on the touch panel 220, and the touch portions 222 on the touch panel 220 are divided by a cutting method. The distribution positions of the touch portions 222 can be designed according to the key positions of the standard keyboard.
綜上所述，本發明較佳實施例中之觸控板是由透明塑 膠薄膜所組成，其厚度較薄，而且，隔板亦可以是由厚度 較薄之薄膜材質所組成。再者，隔板與電路板之間的間隙 亦ΐ需要太大，只要在觸控部未被按壓前，使凸出部與開 關單元不會接觸或開關單元不會被啟動即可。因此，本笋 明較佳實施例之_鍵盤的厚度約可縮,j、至1〜2mm，進^ 使可攜式電腦的整體厚度可以進一步縮小。 # ，本發明已以較佳實施例揭露如上，㈣並非用以 脫=太2’任何所屬技術領域中具有通f知識者，在不 因此本砷和範圍内，當可作些許之更動與潤飾， 為準。，月保瘦範圍當視後附之申請專利範圍所界定者 【圖式簡單說明】 =知一種筆記型電腦薄型鐽盤之結構示意圖。 目。· 為本發明一實施例之一種薄型鍵盤的上視示意 圖3為圖2中之薄型鍵盤之結構示意圖。 9 1321286 0950283 21979twf.doc/n 圖4為圖3之分解圖。 【主要元件符號說明】 100:習知筆記型電腦薄型鍵盤 110 :按鍵 112 :鍵帽 114 :支撐元件 114a、114b :支架 116 :彈性件 116a :罩體 116b :凸出部 120 :電路板 122 :開關單元 T :厚度 200 :薄型鍵盤 210 :電路板 212 :開關單元 220 :觸控板 222 :觸控部 224 :開孔 230 :隔板 232 :上表面 234 :下表面 236 :凸肋 238 :凸出部In summary, the touch panel of the preferred embodiment of the present invention is composed of a transparent plastic film, and the thickness thereof is thin, and the spacer may be composed of a thin film material. Furthermore, the gap between the spacer and the circuit board is also required to be too large, as long as the projection is not in contact with the switching unit or the switching unit is not activated before the touch portion is pressed. Therefore, the thickness of the keyboard of the preferred embodiment of the present invention is about condensable, j, to 1 to 2 mm, so that the overall thickness of the portable computer can be further reduced. # The present invention has been disclosed in the preferred embodiment as above, and (4) is not used to take off = too 2' in any of the technical fields of the art, and in the arsenic and scope, when a little change and retouching can be made , whichever is the case.
