Abstract

Push type mechanical pencil having a chuck (7) for clamping a lead (4), the chuck being operable by a spring loaded push button (12). By pressing the push button, the chuck (7) comes out of engagement with a clutch element for releasing the lead (4) and pushes a lead guide member (3) forward. This lead guide member (3) is provided with the lead brake (2), so that the lead is driven forward together with the guide member (3). In order to ensure that the lead (4) is in the correct writing position, when the push button (12) is actuated only one time, means (15, 16) are provided to transform the radial directed spring force of the chuck (7) into an axial directed force on the lead guide member (3). Preferably the means is an inclined surface on the lead guide member (3) which transforms the radial directed spring force of the chuck (7) into an axial directed desplacement of the guide member (3).
