An ink cartridge style pen (10) with a push-button spring actuator (48) is modified to include an integrally formed stylus tip (12) molded into the writing end of the pen. When the ink cartridge (30) is retracted, the stylus tip (12) is available for use. However, when the ink cartridge (30) is extended, it extends beyond the stylus tip (12) for engagement with paper writing media. The pen (10) allows the operator to quickly and easily switch between writing with an ink tip cartridge (30) to input information with the stylus tip (12) without significant manipulation of the pen.Field of SearchPLURAL TOOLS INCLUDING PROJECTABLE AND RETRACTABLE TOOLIncluding individual actuators Selective individual projection by single actuator With retraction spring PLURAL EXPOSED TOOLS EACH WITH INDIVIDUAL SUPPLY PLURAL TOOLS WITH SUPPLY TO LESS THAN ALL Combined 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 INCLUDING STYLUS Including retraction spring and projected-position retainer Stylus Light pen for fluid matrix display panel Writing digitizer stylus Capacitive or inductive stylus Pressure stylus Light pen EQUIPMENT FOR WRITING, DRAWING, OR FOR FINE ARTS Marking instrument Substantially circular or oval in cross section Element or attachment Single marker with spacing guide | |
