Abstract
Mechanical pencil construction wherein the operational movements to advance the lead are accomplished by providing one or more elastically deformable ribs or spring biased cam members that extend outwardly through axial slots in the pencil body in the normal finger gripping area. The radially inward depression of such ribs or cam members by the writer's fingers is converted to axial motion within the pencil, to thereby effect the necessary lead gripping and advancing operations.
