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. ... A ballpoint pen works exactly the same way. The tiny ball is held in a socket, and the back of the ball is exposed so it can pick up ink from the reservoir.

ANSWER!! :
A ballpoint pen works exactly the same way. The tiny ball is held in a socket, and the back of the ball is exposed so it can pick up ink from the reservoir. The ball fits into the socket with just enough space to move freely.
