Description of the Invention: [Technical Field of the Invention] A wireless keyboard, in particular, relates to a wireless keyboard of a multifunctional universal serial bus. [Prior Art] With the development of the computer industry, the rapid changes in the surrounding areas have been caused. In particular, input devices (keyboards, mice or touchpads, etc.) have also begun to change from the conventional wired connection to wireless transmission. Thanks to the wireless transmission, users can easily move and adjust the most comfortable typing environment. Although the user can conveniently perform various processing of typing on the Internet, due to the signal transmission mode of the wireless keyboard, the user cannot directly perform the direct operation of turning on/off the personal computer and restoring the basic input/output system through the wireless keyboard. The user needs to install a separate cable to use the above Wei. As a result, the convenience of the wireless keyboard is lost. SUMMARY OF THE INVENTION In view of the above problems, the main object of the present invention is to provide a multi-functional universal sequence® flow line wireless hard-receiving personal computer control function. To achieve the above objective, the wireless keyboard of the multi-function universal serial bus disclosed in the present invention comprises a body, a tilting group and an in-line (four) device. The keyboard system has a plurality of buttons, and Wei Weihua has no code circuit. The coding circuit is pressed according to the button to generate a corresponding sub-element signal, and the signal transmission module converts the character signal into a wireless signal and sends a wireless signal; the receiving module will be The received scale signal is transmitted to a 201211830 person, and the embedded controller is installed in the personal computer; the universal serial of the receiving module is difficult to include the clock-controlled lion position. The electric controller is connected to the embedded controller of the personal computer; the embedded controller sends the Weiwei trigger signal to the Nanqiaojing# group according to the length of the received wireless reduction stitch. The present invention provides a wireless keyboard that supports a universal serial bus. The user can use the existing buttons to perform the corresponding functions through different pressing times. In this way, the user can complete the data recovery or clearing of the motherboard without opening the case of the personal computer. With regard to the present invention, the best embodiment of the brain diagram is described in detail below. [Embodiment] Please refer to "Figure 1" for a schematic view of the structure of the present invention.

For example, in a complementary metal-oxide-semiconductor (CMOS), personal computer settings (such as system time, device settings, or peripheral types) are recorded. Therefore, the receiving module 120 can maintain its operating state through the current. Therefore, the present invention can be applied to the personal computer before the power is turned on or after the power is turned on. After receiving the receiving module 120 of the personal computer, the wireless signal is received. Transfer to the embedded controller 130. The embedded controller 130 replaces the wireless signal to 201211830 with a corresponding operation command for the personal computer. Then, the embedded controller: i3〇 drives the corresponding through the south bridge chipset 100 The following is performed when the user presses the function key (corresponding to "Fn," key) on the keyboard body 110 and other keys, and the length of time the encoding circuit 113 is pressed according to the button 111. Generate corresponding function signals. For example, when the Fn and the number of sub-keys are pressed for 3 microseconds, the signal transmitting module 112 sends a wireless signal for increasing the volume to the personal computer. Alternatively, pressing the Fn and the letter key "c", up to 3 micro. In seconds, the signal transmission group 112 will send a corresponding wireless signal to the personal computer, and send the wireless signal of the side-side machine to drive the vehicle (4) to withdraw the film. The invention provides a wireless keyboard supporting a universal serial bus.
