How Pen Worksgg

Pen Technology A pen is a tool used for writing or drawing with a colored fluid, such as ink. A ballpoint pen is a pen that uses a small rotating ball made of brass, or steel to disperse ink as you write

History of the Ballpoint Hungarian journalist Laszlo Biro was well aware of the problems with normal pens. Biro believed that the idea of a pen using a quick-drying ink instead of India ink came to him while visiting a newspaperThe ball would have two functions: It would act as a cap to keep the ink from drying. It would let ink flow out of the pen at a controlled rate.

Ballpoint Design This ball acts as a buffer between paper and the quick-drying ink inside the pen. The ball rotates freely and rolls out the ink as it is continuously fed from the ink reservoir The ball is kept in place -- between the ink reservoir and the paper . As the pen moves across the paper, the ball turns and gravity forces the ink down the reservoir and onto the ball, where it is transferred onto the paper. Rolling mechanism that allows the ink to flow onto the top of the ball and roll onto the paper while at the same time sealing the ink from the air so it does not dry in the reservoir.
