BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic cross-sectional view showing a key structure of a notebook computer. Generally speaking, the thin keyboard of the notebook computer is composed of a plurality of keys, and in order to simplify the illustration, only one of the buttons is shown in FIG. Please refer to FIG. 1 . The conventional notebook computer keyboard 1 〇〇 includes a plurality of uncle keys 110 and a circuit board 120 . The circuit board 12 〇 has a plurality of switch sheets 70 , and each button 11 对应 corresponds to the switch unit 122 . . Each of the keys 10 includes a keycap 112, a support member 114, and an elastic member 116. The support member 114 and the elastic member 116 are disposed between the keycap 112 and the switch unit 丨22 to jointly support the keycap 112. The palpitations are in the 4th type of computer-type thin-type cymbal cymbal cymbal cymbal cymbal (8). The support element 14 is made of two metal materials. The brackets 114a and U4b surround the elastic members 200820044 0950283 21979twf.doc/n 116 and mutually The cross pivot is constructed such that the lower surface of the keycap 112 is substantially parallel to the upper surface of the circuit board 120. Further, the elastic member 116 is usually made of a rubber material and has a cover 116a and a projection (10), wherein the projection 116b is located in the cover 11a. When the user presses the keycap 112, the brackets 114a, 114b will rotate along their pivotal positions, and at the same time, the cover 116a will be elastically deformed to translate the keycap 112 toward the circuit board (four) , ,, thereby The projection 116b contacts and activates the corresponding switching unit 122. In order to meet the needs of notebook computers that are light, thin, short, and small, the components in the notebook are designed to be lighter and thinner. The overall thickness τ of the conventional notebook thin keyboard 100 is approximately dirty, and under the current architecture, the thickness τ is not easily reduced, and thus the overall thickness reduction of the notebook computer is limited. SUMMARY OF THE INVENTION The object of the present invention is to provide a keyboard suitable for use in a thin keyboard to reduce the thickness of a thin keyboard.呵 'Electric shame 溥 The present invention proposes a thin keyboard suitable for use in circuit boards, touch panels, and partitions. The circuit board is self-contained, and the touch panel has a plurality of touch portions and a plurality of openings; ";; should: close units, and the openings are disposed between: ':::. The spacer has an attached On the lower surface of the touch panel, the upper surface and the lower surface of the spacer respectively correspond to a plurality of protrusions. These ribs protrude from these openings. The number of the ribs is increased by the number of the "6" 200820044 0950283 21979twf.doc/n touch portion And these bulges are respectively for Yu Yuyuan. When one of the touches, the switch has a single projection that activates the corresponding switch unit. The preferred closed cell paste film button of the present invention (MetalD〇: keyboard, the above opening: 2. The preferred embodiment of the present invention includes a circuit board (5), a deletion (5), and a (four) ring PCBf Electric f-" tt this day (four) touches the touch-shaped thin disk, the above-mentioned flexible printed circuit (FPC), according to the thin keyboard of the preferred embodiment of the present invention The touch panel is composed of a transparent plastic film. Since the thin keyboard of the present invention has a thin touch panel and a thinner separator, the thin keyboard of the present invention has a thin overall thickness. The above and other objects, features, and advantages of the present invention will become more apparent. FIG. 3 is a schematic structural view of a thin keyboard of FIG. 2, and FIG. 4 is an exploded view of FIG. 3. Referring to FIG. 2 to FIG. 4, the thin keyboard 200 is suitable for being assembled. On a portable computer, it includes a circuit board 2 In the present embodiment, the portable computer is, for example, a notebook computer, 200820044 0950283 21979twf.doc/n. The keyboard 2GG is, for example, a notebook type, portable lightning. Cong Chong soil hard cover in his crying, electronic characters can be personal digital assistant, palm-type amusement ° mouth: the mobile phone 'the invention does not impose any restrictions on this. The circuit board 21 〇 has multiple open 2 with multiple touches The portion 222 has a d:kP and an opening 224. The touch portions 222 correspond to the switch units 212, and the touch portions 222 are disposed between the touch units 222. In the example of the present invention, the touch portion 222 has a relatively upper surface 232 and a lower surface 234, and the surface 232 is attached to the touch panel 22, and the surface 21 〇〇 230 ^^ 232 #t^ 234 ^J; J^ (10) said and a plurality of projections 238. These ribs 236 are divided into the openings 224 to separate the respective touch portions 222, so that the pressure is extracted When the button is pressed, each button can be distinguished by the touch. In addition, the k protrusions 238 correspond to the circuit board 21, respectively. When the touch unit 222 is pressed, the touch unit 222 is adapted to activate the corresponding switch unit 212 through the protrusion 238 on the partition 230. Further, when the touch unit 222 is used, When pressed, the touch portion 222 and the partition plate 230 are elastically deformed to move the protrusion 2% of the partition plate 23 toward the corresponding switch unit 212, thereby contacting the switch unit 212. Then, the switch unit 212 will It is elastically deformed by the pressing of the protruding portion 238, so that the electrode of the switching unit 212 is brought into contact with the electrode of the circuit board 21 to form conduction. In the present embodiment, the circuit board 210 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 PC film printed with a font, and the touch portions 222 on the touch panel 22 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.综: 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 also be composed of a thin film material. Moreover, the gap between the spacer and the circuit board is too large. / Before the touch portion is not pressed, the protruding portion and the switching unit are not in contact or the unit is not activated. Therefore, the thickness of the thin keyboard of the cup embodiment can be reduced to about Umm, so that the overall thickness of the computer can be further reduced. The limited embodiment is disclosed above, but it is not used to deviate from the ordinary knowledge of the present invention. In the case of the invention, it is not necessary to make some changes and refinements in the scope of the invention. The warranty is defined in the scope of the patent.
