Abstract

An electronic pen comprises a retractable cartridge having a nib, a force-actuable device that is actuated by a nib force transmitted axially through the cartridge from the nib, a retraction for retracting the cartridge, a button for actuating the retraction mechanism, and a decoupling mechanism for biasing the button away from coupled engagement with the retraction mechanism and thereby the force-actuable device.
