Who invented mechanical pencil?

The pen and mechanical pencil commonly used by people were also invented by Croatian Edward Pankara. Now the word "Pen" in English comes from his name.

Compared with Japanese brands Sony and Canon, Sharp is familiar to consumers in China, and it seems that Sharp is "very far away". However, with the arrival of a new era, China consumers may no longer be able to ignore Sharp, that is, the era of LCD TV.

With the strength of technological innovation, the Japanese company that invented mechanical pencil found two major technological innovation paths for development in the new century-Sharp. With 33 years of experience in LCD business, it is not only the "father of LCD", but also ranks first in the world in the field of solar cells.
