At the same time, the touch keyboard projects the keyboard logo on the touch screen through a projector for the user to operate, and the touch keyboard design has a novel overall appearance. 0992035735-0 099120229 Form No. A0101 Page 3 / Total 19 Pages 2010201047 [Embodiment] [0006] Referring to FIG. 1 and FIG. 4, a first preferred embodiment of the present invention discloses a touch keyboard 100. As an input device for devices such as computers or printers. The touch panel 10 includes a touch screen 10, a substrate 30, a projection device 50, and a control module 70. The touch screen 10 and the projection device 50 are disposed on the substrate 30. The control module 70 is connected to the touch screen 10. [0007] Referring to FIG. 2, the touch screen 10 is a transparent transparent capacitive touch screen including a transparent protective layer 12, a first conductive layer 14, a transparent substrate 16, and a second Conductive layer 17 and a keyboard connection 18. The transparent protective layer 12, the first conductive layer 14, the transparent substrate 16, and the second conductive layer 17 are stacked in this order from top to bottom. In this embodiment, the transparent protective layer 12 is made of a polyethylene terephthalate (PET). The first conductive layer 14 is a working layer for detecting and positioning, and is made of other transparent conductive materials such as indium tin oxide (IT0), zinc oxide doped aluminum (ZA0) or cadmium oxide (CdO). The transparent substrate 16 can be a glass plate or a transparent plastic plate. The second conductive layer 17 is made of a transparent conductive material as a mask layer to ensure that the touch screen 10 has a good working environment. One end of the keyboard connection 18 is connected to one side of the touch screen 10, and the other end is connected to a terminal device such as a computer. Referring to FIG. 1 and FIG. 3, in the embodiment, the substrate 30 is made of a transparent material such as glass or resin, and has an arc-shaped structure as a whole, and the central portion is slightly recessed. The substrate 30 includes a surface 32 and a bottom surface 34. The substrate 30 can be attached to the side of the touch screen 10 away from the transparent protective layer 12 through the surface 32. One side of the surface 32 of the substrate 30 defines a rectangular recess 322. One side of the bottom surface 34 of the substrate 30 is protruded from the substrate 30 and is inverted triangle 099120229. Form No. A0101 Page 4 of 19 0992035735-0 201201047 The transparent support ribs 36' are shaped such that the touch keyboard 100 is slightly tilted when placed on a table top. [0009] The projection device 50 includes a support body 52 and a projector 54 mounted in the support body 52. The support body 52 may be made of a transparent material. One end thereof is rotatably fixed to the substrate 3A and rotatably received in the recess 322. The projector 54 is disposed at one end of the support body 52 away from the recess 322 and is operated by a battery power supply or other signal line transmission power source. The projector 54 is activated when the support 52 is rotated to a position perpendicular to the substrate 30, and the projector 54 emits a beam of light to completely project the plurality of button marks 56 on the touch screen 1''. The projection screen can be designed according to actual needs, such as English letters, Chinese characters or Japanese characters, etc., and the control module 70 can be an integrated chip, which is arranged on the chain connection. 18, and electrically connected to the first conductive layer 14, the second conductive layer 17, and the keyboard line 18 through a flexible cable (not shown). The information of the key selection flag 56 projected by the projector 54 when the set of the selected body 52 is perpendicular to the substrate 3 is preset in the control module 70 (such as the coordinate range information of the projection area where the K key is located and the corresponding instruction information). And corresponds to the position where the touch screen is bumped. When the user's finger or other object touches the transparent protective layer 12 of the touch screen 1 , a capacitive effect is generated. The control module 70 can generate a coordinate of the finger or the object touch position by detecting the change of the current. a corresponding instruction information, and the instruction information is transmitted to a terminal device such as a computer 099120229. Referring to FIG. 4, when the touch keyboard 1? is needed, the support body 52 is unscrewed from the groove 322, and The support 52 is perpendicular to the substrate 3A. At this time, the projector 54 emits a beam of light which will be projected on the touch screen 1 〇 page 5 / 19 pages form number A0101 0992035735-0 [0011] 201201047 when the user touches the touch screen 10 The control module 7〇 will judge the position of the touch and record the coordinate information of the touch position. At the same time, the control mode=0 is the coordinate information of the touch position and the pre-stored button identifier 56. The comparison information is used to display the command information corresponding to the touched button identifier 56 and display it through a terminal device such as a display. [0013] FIG. 5 shows a second preferred embodiment of the present invention, which is different from the first preferred embodiment in that the substrate 30 is made of a non-transparent material, and the support body 52 includes a connecting portion 522. a rotating portion 524 and a hinge 526. One end of the connecting portion 522 is disposed in the recess 322. The rotating portion 524 can be rotatably disposed at the other end of the connecting portion 522 through the hinge 526 and form a specific angle with the connecting portion 522. The projector 54 is mounted in the rotating portion 524. When the touch keyboard 100 is used, the support body 52 is first unscrewed from the recess 322 and the connection «Ρ 522 is perpendicular to the substrate 3 〇, and then the rotating portion 524 is rotated to the specific angle. The beam light projects the button mark 56 on the touch screen 10. At the same time, the control module 7 calculates the command information corresponding to the touch position according to the information of the preset button mark 56 according to the specific angle. When the use is finished, the rotating portion 524 is rotated in the opposite direction to be flat with the connecting portion 522 to be received in the recess 322. Compared with the first preferred embodiment, 'because the projector 54 installed in the rotating portion 524 forms a certain angle with the substrate 30', the button mark 56 can be completely projected to the touch without using the support body 52 having a higher height. Control screen 1 〇. FIG. 6 shows a third preferred embodiment of the present invention. The difference from the second preferred embodiment is that an angle sensor 528 is mounted on the hinge 526 of the support body 52. When the rotating portion 524 is rotated, The angle sensor 528 detects the angle between the rotating portion 524 and the connecting portion 522 to generate an angle signal and will be 099120229 Form No. A0101 Page 6 of 19 Page 0992035735-0 201201047 ❹ [0015] The angle signal is transmitted to the control module 70 through the electrical trace. The control mode 'and 70 pre-agreement group and the information of the button identifier 56 corresponding to different angles 曰 when the touch keyboard 1GG is used, the rotating rotating portion and the surface 32 of the substrate (10) are maintained at an arbitrary angle, (10) all the button marks are completely projected The control module 7G can calculate the command corresponding to the touch position of the user according to the angle signal transmitted by the angle sensor 528 and the information of the preset button identifier 56 on the touch screen 1G. For example, since the control module 7G stores the information of the button identification 蛉 at different angles of the plurality of sets of rotating portions 524 and the connecting portion 522, the angle between the rotating portion Mg and the connecting portion 52 2 can be described as a projection. The effect is even more awkward.
