Problems solved by technology

[0003] However, there are more and more keys on the keyboard, so that when the operator uses the computer keyboard, he often presses some keys of the keyboard by mistake, resulting in misoperation, affecting the normal operation of the current program, and causing unnecessary troubles.
For example, when an operator uses a computer to run full-screen software, such as a computer game, the window key is usually located between the Ctrl and Alt keys, and Ctrl and Alt are one of the commonly used combination shortcut keys. When operating shortcut keys, the window key is often pressed by mistake, which minimizes the program interface and affects the game process

Embodiment Construction

[0009] Such as figure 1 As shown, the keyboard 300 includes a keyboard body 310, a plurality of keys 320 arranged on the keyboard body 310 and a key lock switch 330, the key lock switch 330 is used to control whether one or more of the plurality of keys 320 is locked . see figure 2 , the following uses a certain key 322 on the keyboard 300 as an example for illustration. The keyboard 300 also includes a controller 340. The controller 340 has several input and output ports PAO, PBO, etc. The row and column lines 342 and 344 are drawn out from the input and output ports PAO and PBO to form a row and column scanning matrix of keyboard keys. The button 322 has a first conductive end 324 and a second conductive end 326 . The key lock switch 330 is a push-type switch and has a first contact 332 and a second contact 334 .

[0010] 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 th...

Abstract

The invention provides a keyboard on which keys can be locked or unlocked. The keyboard comprises a keyboard body, a plurality of keys arranged on the keyboard body, a controller and a key-locking switch. The controller is provided with a plurality of I / O ports, and row-column lines led out of the I / O ports form a row-column scanning matrix. At least one of the keys is electrically connected with a row line or column line corresponding to the key by the key-locking switch. The key-locking switch controls on / off between the key and the row line or column line so as to make the key locked or unlocked. With the arrangement of the key-locking switch on the keyboard, the key on the keyboard can be locked when not used, thereby avoiding maloperation of an operator.

Description

technical field [0001] The invention relates to a push-button keyboard, in particular to a push-button keyboard suitable for computers. Background technique [0002] Along with popularizing day by day of computer, keyboard has also obtained great development as a kind of direct input device of computer. Since the release of IBM PC, the keyboard has experienced 83 keys, 84 keys, 101 keys, and 102 keys. After Windows 95 came out, it was improved into a 104 / 105 keyboard, which added two Windows (Windows) keys, and the key functions of the keyboard were improved. It also brings convenience to users. [0003] However, there are more and more keys on the keyboard, so that the operator often presses some keys of the keyboard by mistake when using the computer keyboard every day, resulting in misoperation, affecting the normal operation of the current program, and causing unnecessary troubles. For example, when an operator uses a computer to run full-screen software, such as a com...
