Description

Assembled keyboard{custom keyboard}

The present invention relates to a prefabricated keyboard, and more particularly, to a prefabricated keyboard with improved usability.

In general, a keyboard is a computer input device that looks like a typewriter, and is also referred to as a keyboard, a letter board, or a key board. Korean, English, numbers, special characters, etc. are input through this keyboard, and it cannot be used alone, and the input is performed while confirming the input by forming a pair with a video display device, for example, a monitor.

In the beginning, the number of keyboards was about 83 or 84, but as the function was expanded, the number gradually increased to 101, 103, 106, etc. In addition, most of the commonly used keyboards are for Windows with 106 characters. At this time, the keyboard is divided into Korean 2-beolsik, Korean 3-beolsik, English qwerty and English Dvorak keyboards according to the arrangement of the keyboards.

Here, English QWERTY is a standard American keyboard, and the English letters in the first line under the number keys are in the order of Q, W, E, R, T, Y from the left of the keyboard, so it is the most commonly used keyboard layout. am.

Such a keyboard has a structure in which a main body case is formed with an upper case and a lower case, a PCB board or the like is provided inside the main body case, and a plurality of key modules or key caps protrude through the upper case.

However, the conventional keyboard is difficult to disassemble and assemble except for skilled technicians, and it is impossible to arbitrarily modify the design.

In addition, conventional mechanical keyboards have a unique internal resonance due to a housing structure composed of an upper plate and a lower plate, and thus, there is a problem in that annoying unison occurs when keys are keyed in a quiet place.
