An automatic mechanism for driving writing implements, characterized in that they consist in terminal appendages of both writing tips, irregular internal profiles that complement the lateral profiles of an intermediate piece between them and oscillating on a transverse axis mounted on the external wrapping body, so that by rubbing actions between the intermediate piece and both end appendages, a partial rotation of the latter takes place, immobilizing a writing tip in the service position.
