Description of the Invention: [Technical Field] The present invention relates to an input device, and more particularly to a computer keyboard. [Prior Art] With the rapid development and rapid spread of network technology, computers have become an indispensable tool for people to work, live and learn. Computers are the best choice for home and fixed office because of their high performance, scalability and affordability. The development of technologies such as multimedia playback, Internet access and wireless connectivity has enabled computers to be given more and more functions. People use the Internet to access information, watch movies, and enjoy music. The computer mainly includes a host, a display and a keyboard, and the host is used for receiving and executing various operation commands input by the user through the keyboard, and the display is used for displaying an operation interface and an image message. Due to the convenience of using the computer and the large storage capacity, more and more people are storing some important work materials and personal information on the computer. For example, people use w键盘rd 0 to input text messages using the keyboard to complete various text-editing: storing the document files in the internal memory of the host. However, the above document file is easily opened by others and edited by keyboard editing. As a result, information security is not guaranteed, resulting in the destruction of important work materials and personal information. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a keyboard that can protect information security. The computer keyboard has a plurality of buttons, and the plurality of buttons are divided into a button area and a second button area. The computer keyboard further includes a storage unit, a verification unit, and a locking unit, wherein the storage unit is configured to store password data set by the user; the first button area is configured to receive a user operation, and generate an input password; the verification form s is used to input The password is compared with the set exhaustive data for password verification, and an unlocking signal is issued to the locking unit when the verification is passed; the locking unit is used when the keyboard is activated or based on the user's button area or/and the second button The predetermined operation on the area locks the second button area and unlocks the second button area according to the unlock signal provided by the verification unit. By using the password verification method, the user can operate the computer by inputting an instruction through the second button area when the password is verified. In this way, information security can be effectively guaranteed. [Embodiment] FIG. 1 is a schematic structural view of a computer keyboard according to a preferred embodiment. The computer keyboard 1 has a plurality of buttons 2, and the plurality is divided into a first button region 22 and a second button region by pressing ❹20. In this embodiment, the first button area 22 is the sub keypad of the right side of the computer keyboard 1 , and the second button area 24 is the main key area of the left side of the computer keyboard 10 . Referring to Fig. 2', it is a functional block diagram of the computer keyboard 1 shown in Fig. i, which includes a first button area 22 and a second button area 24, a storage unit 26, a verification unit 28, and a locking unit 30. The storage unit 26 is configured to store password data set by the user. The first button area 22 is for receiving user operations and generating an input password. The verification unit 28 is configured to compare the input password with the set password ratio 8 200949612 for password verification, and issue the unlock notification given unit 30 when the verification is passed. The locking unit 30 is configured to lock the second button area 24 when the keyboard is activated or based on a predetermined operation of the user on the first button area 22 or/and the second button area 24, and is released according to the unlocking signal provided by the verification unit 28. Locking of the second button area 24. The locking of the second button area 24 is to disable the button in the second button area 24. The disabling mode may be to disconnect the working power of the second button area 24, or to block the output of the second button: the field 24, or even It is possible to disturb the output of the second button area. The division of the first button area 22 and the second button area 24 may also be other forms, such as the first button area 22 being a digit key or a letter key of the computer keyboard 1 〇 main keypad, and the other keys being the second button area 24. . When the computer keyboard 1 is used, the user can prevent other users from operating the computer system by using the computer keyboard 1 by locking the second button area 24. Moreover, when the user computer system has a power-on password, other people may also It is impossible to input the password normally by the keyboard, and the user information security is effectively guaranteed. In summary, the present invention complies with the invention patent requirement, and the above is only a legal statement. The above description is only a preferred embodiment of the present invention. The equivalent modifications or changes made by those who have learned the skills of the case in the context of the creation of the case shall be included in the scope of the following patent application.
