In 1958, the United States pioneered data communications by combining information transmission with computers. From then on, data communications became a direct part of social production. Since then, computers have permeated every aspect of human society, profoundly changing its very nature.

[0003] As the most common information input device for electronic computers, the importance of keyboards is self-evident. If the CPU is the heart of the computer and the monitor is the face of the computer, then the keyboard is the mouth of the computer. It is the keyboard that enables smooth communication between people and computers. There are multiple keys on the keyboard, and keycaps came into being to make it easier for people to press the keys. A keycap is a small plastic cap-shaped component that is buckled on the top of the keyboard keys and marked with the function or numbers and letters of the corresponding keys. The numbers and letters on the keycaps currently on the market are marked on the top of the keycaps, which are easily worn and damaged. The numbers and letters on the keycaps that have been used for a long time are usually severely worn and difficult to identify, which is not convenient for people to use. Therefore, a mold for the production of side-engraved character keycaps is provided. Utility Model Content
