Abstract

Disclosed is a pen configured for use as an electronic stylus with a tablet in a pen-based computer input system. The pen includes a barrel, forming an outer surface, and a stylus tip, which can be extended from the barrel to facilitate use of the pen to draw, or retracted within the barrel to facilitate use of the pen as a pointer.

Electronic Pen with Retractable Tip

      Disclosed is a pen configured for use as an electronic stylus
with a tablet in a pen-based computer input system.  The pen includes
a barrel, forming an outer surface, and a stylus tip, which can be
extended from the barrel to facilitate use of the pen to draw, or
retracted within the barrel to facilitate use of the pen as a
pointer.

      Figs. 1 and 2 are isometric views of a first version of the
pen.  The stylus tip 1 is extended from the barrel 2, as shown in
Fig. 1, by depressing a pushbutton 3 at the top of the pen, and
retracted, as shown in Fig. 2, by again depressing the pushbutton 3.
The internal mechanism (not shown) for alternately extending and
retracting the tip 1 with repeated depressions of pushbutton 3 is
well known in the art of ball point pen manufacture.

      Figs. 3 and 4 are isometric views of a second version of the
pen.  The stylus tip 4 is extended from the lower barrel 5, as shown
in Fig. 3, by rotating the upper barrel 6 about its axis in the
direction of arrow 7, relative to lower barrel 5.  The stylus tip 4
is retracted, as shown in Fig. 4, by rotating the upper barrel 6
opposite the direction of arrow 7, relative to lower barrel 5.
Again, the internal mechanism (not shown) for extending or retracting
the tip 4 is well known in the art of ball point pen manufacture.
While the device of Figs. 1 and 2 is generally easier to use if the
pen is not tethered, the device of Figs. 3 and 4 has particular
advantages if tethering is...
