[Technical field of invention] The present invention relates to a combination key anti-missing method and an electronic device using the same, and more particularly to a combination of a touch button and a mechanism button to prevent mis-touch Method and electronic device using the method. [Prior Art] Witnessing mobile phones has become an indispensable tool in the daily work and life of people in modern society. The mobile phone buttons on the market generally only have touch buttons or ® only mechanism buttons, and there are fewer mobile phone buttons with two kinds of button combinations. The main reason is that such mobile phone combination buttons are easy to cause user's false touch, as shown in the figure. The block distribution map of the combination button of the mechanism button and the touch button shown in FIG. 1 , the mechanism button block 10 and the touch button block 2 叹 respectively have the direction button and the multi-function button of the mobile phone, as shown in the figure. As shown in FIG. 2, when the user presses a button of a certain mechanism, the finger thereof is often easy to touch both the button of the mechanism button and the button of the touch button, that is, when the user presses the button of the mechanism button. At the same time, the touch button block 20 will be triggered, so that the mechanism button and the touch button simultaneously function, thereby affecting the normal use of the mobile phone. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a combination key anti-missing method for reducing the probability of false touch to ensure the normal use of the electronic device and using the sub-device. The combination key anti-missing method is used for the anti-missing of the combination of the mechanism button and the touch button. The combination key anti-missing method first sets the false touch 6 201010390 to detect the block, when a certain button is When the button is pressed, if the touch button is not touched, the touch button does not work. If the touch button is touched, the touch button is determined according to whether the touch detection block is triggered. The function of the hair: If the false touch detection block is triggered, the touch signal of the touch button is not sent to the central processing unit. If the false touch detection block is not triggered, the touch button is The touch action signal is sent to the central processing electronic device, including a set of mechanism buttons, a set of touch buttons® and a set of false touch detection keys, and the false touch detection keys are distributed between the touch buttons . The combination key anti-missing method and the electronic device using the method can reduce the false contact probability of the combination key by adding the false touch detection block and the false touch detection key, thereby greatly reducing the negative of the user due to the operation error. The effect is to ensure the normal use of the electronic device. [Embodiment] Hereinafter, a combination key anti-touch method of the present invention and an electronic device using the same will be further described in detail with reference to the accompanying drawings and preferred embodiments. The combination key anti-missing method of the preferred embodiment of the present invention is applied to an electronic device. The following is an example of application to a mobile phone. Referring to FIG. 3, the mobile phone 35 using the combination key anti-missing method of the present invention is provided with a set of mechanism buttons 32, a set of touch buttons 34 and a set of false touch buttons 36. The mechanism button 32 and the touch button 34 respectively include a four-directional button and a function button, and the false touch detection button 36 is distributed between the mechanism button 32 and the touch button 34. The touch button 34 and the false touch detection button 36 are preferably capacitive touch 7 201010390 type buttons, and may also be other touch buttons such as resistive touch buttons. «The month reference circle 4, the mechanism button 32, the touch button 34 and the false touch detection button 36 are respectively provided with a mechanism button block 42, a touch button area _ block 44 and a false touch detection block 46. . The false touch detection block 46 is located around the mechanism button block 42 and distributed between the touch button blocks 44, and separates each adjacent two touch button blocks 44. When the mechanism button 32 is pressed or the touch button 34 and the false touch detection button 36 are touched, the mechanism button block 42 located below, the touch button block 44 and the false touch detection block® 46 Triggered to send the corresponding instruction. Referring to FIG. 5, the mobile phone 35 is provided with an integrated circuit 48 and a central processing unit 49. The integrated circuit 48 is electrically connected to the central processing unit 49 for responding to the mechanism button block 42 and the touch button block 44. And the signal that is triggered by the error detection block 46 is processed and sent to the central processing unit 49 to execute an instruction corresponding to the trigger signal. The integrated circuit 48 in the mobile phone 35 can be triggered by the hardware button or the touch button block 44, the touch button block 44 and the false touch detection block 46 by hardware or firmware. The trigger signal of the touch panel block 44 is not sent to the central processing unit 49. In addition, when the touch button block 44 and the false touch detection block 46 are simultaneously triggered, the trigger signal of the touch button block 44 is not transmitted to the central processing unit 49, but when the mechanism button block 42 is used. When the false touch detection block 46 is triggered at the same time, the trigger signal transmission of the mechanism button block 42 is not affected. Referring to FIG. 6, when the user presses a certain mechanism button 32, the finger 50 tends to touch the touch button 34 or the false touch detection button 36 near the mechanism button 32 at the same time, and may also touch at the same time. When a touch button 201010390 is pressed, the anti-missing 34 and a false touch detection button 36 appear in these cases. Described by principle. Please refer to FIG. 7 , the principle of the anti-missing of the combination key of the present invention is as follows: when the user presses a certain mechanism button 32, it is determined that the touch button block 44 is triggered by the user, and if the touch button block 44 is If the trigger button 34 is not activated, the integrated circuit 48 only transmits the signal command triggered by the mechanism button block ^; if the touch button block 44 is triggered, it is further determined whether the error (four) block 46 is detected. It is triggered by the user, and determines whether the touch button ^ acts according to the situation that the false touch detection block 46 is triggered: if the false touch detection block 46 is triggered, the user's action triggers the mechanism button at the same time. The block 42 , the touch button block 44 and the false touch detection block 牝, the integrated circuit 48 does not send the user's action signal to the touch button %, that is, the touch button block 44 is triggered. The signal is not sent to the central processing unit 49; if the false touch detection block 46 is not triggered, the user's action only triggers the mechanism button block 42 and the touch button block _ 44 at the same time. The integrated circuit 48 will send the user's action signal to the touch button 34. That is, the signal that the touch-sensitive button block 44 is triggered will be sent to the central processing unit 49. In this case, the error can be further reduced by the mobile phone%=set an anti-missing software control program' Touch rate. Of course, by appropriately designing the area and arrangement of the false touch detection button 36, such as setting a ring-shaped false touch detection button 36 around the mechanism button 32, the mechanism button block 42 and the touch can be avoided as much as possible. The type button block 44 is simultaneously triggered 'and the false touch detection block 46 is not triggered. The above-mentioned combination key anti-missing method is provided because the mobile phone 35 is provided with an erroneous touch 9 201010390. The detecting block 46 can effectively reduce the user's ambience rate, and (4) greatly reduce the user's negative impact due to operational errors, and make the action Phone 35 is more capable. It is enough for normal use. With the above-mentioned combination key to prevent mis-touching, the mobile phone (3) needs space for the area of the false touch detection key 36 to be routed and the pad (PAD). : = The invention has indeed met the requirements of the invention patent, 遂 = = ^ ^ ^. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
