Abstract:
1. A writing device for use on both paper and electronic substrates, the writing device comprising: a hollow shaft having a distal end and a proximal end along a longitudinal axis; a writing cartridge at least partially disposed within the hollow shaft and movable along the longitudinal axis between a writing position and a stylus position, the writing cartridge having a distal end corresponding with the distal end of the hollow shaft, and a proximal end corresponding with the proximal end of the hollow shaft; a writing tip located at the distal end of the writing cartridge; and a stylus tip connected to the distal end of the shaft, the stylus tip having an orifice centered along the longitudinal axis that opens into a cavity such that, when the writing cartridge is in the writing position, the writing tip extends beyond the cavity and through the orifice, but when the writing cartridge is in the stylus position, the writing tip is housed within the cavity; wherein, when an exterior surface of the stylus tip is pressed against a flat surface of a capacitive touch screen and when the writing cartridge is in the stylus position, the exterior surface absorbs the pressure and conforms to the flat surface, forming a contact patch between the writing device and the capacitive touch screen sufficient to facilitate electrical conduction from the writing device to the capacitive touch screen.
