Description of the Invention: [Technical Fields of Invention] [0001] The present invention relates to a keyboard', and more particularly to a keyboard that can prevent erroneous operations. [Prior Art] [0002] The keyboard is the most common computer input device. It is widely used in various terminal devices such as microcomputers. Usually, the keyboard provides a button cap that the user directly taps. Most keyboards are getting smaller and smaller, so that when we hit _ a button cap, the surrounding buttons are also triggered. Causes the user to input gamma into the wrong character or command' thus affecting the user's normal use of the keyboard. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a keyboard that can avoid erroneous operations caused by the keycap being too small. [0004] A mishandling prevention keyboard includes a substrate, a button and a controller, the button The utility model comprises a cylinder, a piston, a piston rod, a keycap and a pressure sensor. The cylinder is provided with a receiving cavity having an opening at one end, and the receiving cavity is filled with a buffering medium. Provided in the cylinder, the two ends of the piston rod are fixedly connected to the key cap and the piston respectively, and the pressure sensor is disposed on the inner wall of the rainbow tube for detecting the pressure value in the cylinder tube. The character or command corresponding to the button with the largest value is input to the host device. [0005] The keyboard is used as an input device, which can effectively avoid the above-mentioned erroneous operation input, and thus is convenient for the user to use. [Embodiment] [0006] 099143344 Please refer to FIG. 1, which partially illustrates the prevention of misoperation of the keyboard 1. The keyboard i package 0992075087-0 Form No. A0101 Page 3 of 7 201225129 includes a substrate 10 and a plurality of buttons 20 disposed on the substrate 10. The button 20 includes a cylinder 21, an end cap 22, a piston 23, a piston rod 24, a keycap 25 and a pressure sensor 26. The cylinder tube 21 is provided with a housing chamber 27 having an opening at one end. The receiving chamber 27 is filled with a buffer medium, and the buffer medium includes a hydraulic medium or a pneumatic medium. The piston 23 is slidably disposed in the housing chamber 27. The end cap 22 is fixed to the outlet end of the receiving cavity 27 for preventing the piston 23 from being disengaged from the cylinder tube 21. The piston rod 24 is fixed at the end to the piston 23, and the other end is fixedly connected to the key cap 25 after passing through the end cover 22. The inductor 26 is disposed on the inner wall of the cylinder tube 21 for detecting the pressure value in the cylinder tube 21. In the embodiment, the button 20 further includes an elastic member 28. The elastic member 28 is a spiral spring, and its two ends are respectively fixed to the piston 23 and the bottom of the cylinder tube 21 for blocking the piston 23 from sliding into the bottom of the cylinder tube 21. When the keycap 25 on the keyboard 1 is tapped, the piston 23 slides toward the bottom of the cylinder 21. The sensor 26 detects the pressure value in the cylinder 21, and the controller (not shown) in the keyboard 1 inputs the character or command corresponding to the button 20 having the largest pressure value to the host device, thereby preventing the plurality of buttons 20 from being The wrong input caused by the trigger. [0010] While the invention has been described and described with respect to the preferred embodiments of the present invention, it will be understood that various changes and modifications may be made without departing from the true scope of the invention. It is therefore intended that the invention not be limited to the particular embodiments of the invention disclosed herein, 099143344 Form No. A0101 Page 4 of 7 0992075087-0 201225129 [Simple Description of the Drawings] [0011] FIG. 1 is a schematic diagram of a keyboard according to a preferred embodiment of the present invention.
