More specifically, the writing implement comprises an elongated body portion including a first end, a second end and an outer surface constructed and arranged to be gripped by a user. Located within an interior chamber of the body portion is a retractable ink cartridge actuated by a conventional push button/spring biased actuator. The stylus tip is preferably integrally formed with the outer surface of the first end of the body portion extending forwardly from the first end of the body portion such that the stylus tip is presented for use when the body portion is gripped by a user in a normal writing grip. The ink cartridge is normally moveable between a first, retracted position wherein the writing tip of the ink cartridge is disposed within the interior chamber of the body portion and the stylus tip is exposed for use, and a second, extended position wherein the writing tip extends outwardly from the interior chamber beyond the first end of the body portion for engagement with a conventional paper writing media.Field of SearchCombinedCOMBINED PLURAL TOOLS WITH SUPPLY TO LESS THAN ALL PLURAL EXPOSED TOOLS EACH WITH INDIVIDUAL SUPPLY With retraction spring Selective individual projection by single actuator Including individual actuators PLURAL TOOLS INCLUDING PROJECTABLE AND RETRACTABLE TOOL Including retraction spring and projected-position retainer INCLUDING STYLUS PROJECTABLE AND RETRACTABLE TOOL Retainer guided in orbital path (e.g., rotary indexing) And mechanical-movement actuator Including laterally or circumferentially movable keeper And separate release member For releasing flexibly-biased keeper Stylus Light pen for fluid matrix display panel Writing digitizer stylus Capacitive or inductive stylus Pressure stylus Light pen Substantially circular or oval in cross section EQUIPMENT FOR WRITING, DRAWING, OR FOR FINE ARTS Element or attachment Marking instrument Single marker with spacing guide | |
