Auto-Advance mechanism
Revision as of 05:13, 5 September 2020 by Paraxylene (talk | contribs) (→Auto-advance pencil models)
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.
