Abstract
A writing instrument includes a travel multiplier mechanism that includes a cam member that pivots about a pivot axis in response to motion of a push button member. The cam member engages a sliding piston member in order to provide a travel multiplying effect such that a distance of travel of the sliding piston member exceeds a distance traveled by the push button member.
