Field of the Invention The present invention relates to a push button type keyboard, and more particularly to a push button type keyboard suitable for a computer. [Prior Art] With the popularity of computers, the keyboard as a direct input device for computers has also been greatly developed. Since the introduction of the IBM PC, the keyboard 经历 has experienced 83 keys, 84 keys and 1 〇 1 keys, 102 keys, Wind 〇ws% has been improved, and has been improved into a 104/105 keyboard, adding two windows (Wind〇ws) The key function of the keyboard and keyboard has been enhanced, and it has also brought convenience to the user. However, there are more and more buttons on the keyboard, which makes the operator often press some keyboard keys when using the computer keyboard every day, which leads to misoperation, and the normal operation of the mobile phone, which causes unnecessary trouble. For example, when a person using a computer to run a full-screen software, such as a computer game, the window keys are usually located between the plus and the Alt keys, and *(10) and cents are one of the common shortcut keys used by the operator. When using Ait as a shortcut key = 乍, you will often press the window key ' to minimize the program interface and affect the process. SUMMARY OF THE INVENTION Here, it is necessary to provide a keyboard that prevents erroneous operations. The package; te j (four) 'key remaining key can be locked or unlocked. The keyboard controls and the Z is placed on the body with a number of buttons, controls and lock switches. ‘Key I:, 丨: Dry I/O 埠’ Input/Output 埠 Leads the row and column lines to form the scan matrix of the button. At least one of the buttons is locked by a lock. The 200928872 key switch is electrically connected to the row or column line corresponding to the button. The lock switch controls the opening and closing of the button and the line or column line so that the button is locked or unlocked. By setting the lock switch on the keyboard, the above keyboard can be locked by pressing the ' key on the keyboard, thereby preventing the operator from operating incorrectly. [Embodiment] As shown in FIG. 1 , the keyboard 300 includes a body 310, a plurality of buttons 320 disposed on the body® 310, and a lock switch 330. The lock switch 330 is configured to control one or more of the plurality of buttons 320. Whether it is locked. Referring to FIG. 2, a button 322 on the keyboard 300 will be described below as an example. The keyboard 300 further includes a controller 340 having a plurality of input and output 埠ΡΑ0, ΡΒ0, etc., and the row and column lines 342, 344 are drawn from the input and output 埠ΡΑ0, ΡΒ0 to form a matrix scan matrix of the keyboard keys. The button 322 has a first conductive end 324 and a second conductive end 326. The lock switch 330 is a push switch having a first contact 332 and a second contact 334. The first conductive end 324 of the button 322 is electrically connected to the row line 342. The first contact 332 and the second contact 334 of the lock switch 330 are electrically connected to the second conductive end 326 and the column line 344 of the button 320, respectively. The key switch 330 is used to control whether the second conductive end 326 is in communication with the column line 344 to cause the button 322 to be locked or unlocked. When the button 322 is required to be used, the lock switch 330 is depressed to cause the second conductive end 326 to communicate with the column line 344, and the button 322 is unlocked. At this time, if the button 322 is pressed, the controller 340 will receive the electrical signals of the row line 322 and the column line 344 corresponding to the button 322, and return to the 200928872 button operation. Conversely, when the button 322 is not required to be used, the pop-up lock switch 330' causes the second conductive end 326 to be out of communication with the column line 344, and the button 322 is locked. At this time, if the button 322 is pressed, the controller 340 does not receive the electrical signal of the column line 344 corresponding to the button 322, and does not respond. In this embodiment, the button 322 is a window key on the keyboard 3. The lock switch 330 is disposed on the left side of the keyboard 300. The lock switch 33A is not limited to the push switch, and may be other types of switches such as a toggle type. In other embodiments, the first contact 332 and the second contact 334 of the lock switch 33 are electrically connected to the first conductive end 324 and the line 342 of the button 322, respectively. The lock switch 33A is used to control whether the first conductive end line 342 is connected or not, so that the button 322 is locked or unlocked. The keyboard 300 is provided on the keyboard 3〇〇 by the keyboard 300. One or a plurality of buttons 32 〇 can be locked without being needed, thereby preventing the operator from misoperation. 0 财 fr 'The invention is in line with the payment of the financial materials, and the remaining expertise is only For the preferred embodiment of the present invention, the equivalent modification of the above-mentioned (4) fine modification of the present invention should be included in the following patent application.
