Some auto-advance pencils. Left to right: two different models of Faber-Castell Grip Matic, a Faber-Castell Poly Matic, a BIC AI, and two Maped Automatic (0.5mm and 0.7mm)

Auto-advance or auto-feed mechanical pencils don't need any action to advance the lead because of their particular mechanism: a spring-loaded sliding sleeve (usually a plastic cone) pushes out more lead every time it is pressed and released from the paper. In order to work, it is required to write with a very little amount of lead coming outside the tip, and practically to drag the lead sleeve on the paper. Most of the time these pencils are also provided with a push button mechanism, and can be used in the classical way.

Examples of auto-advance pencils that are not provided with a push button mechanism. Top to bottom: a Paper Mate Advancer, a Fila Temagraph Automatic, and a M&G Comrade
