Abstract

Current pens can be bought that can draw in different colors. These pens consist of a group of several ballpoints with different colors of ink, and those can be selected by a user, the appropriate ball point is extended and centered, and the user then uses it to write. As the number of different colors selectable increases, so does the width of the pen, making them difficult to use. The idea disclosed shows a way of creating a pen that would be able to be used to produce huge number of different colors (typically in the range of 64 million), and allow the color to change in a continuous manner, heretofore not possible with a pen.

Ink Jet Pen System

   Current pens can be bought that can draw in different
colors.  These pens consist of a group of several ballpoints with
different colors of ink, and those can be selected by a user, the
appropriate ball point is extended and centered, and the user then
uses it to write.  As the number of different colors selectable
increases, so does the width of the pen, making them difficult to
use.  The idea disclosed shows a way of creating a pen that would be
able to be used to produce huge number of different colors (typically
in the range of 64 million), and allow the color to change in a
continuous manner, heretofore not possible with a pen.

   The invention is to take a section of a printhead,
normally used in an inkjet printer, only using 3 or 4 holes, so as to
produce the colors typically mixed for a single stream of color, put
that into the head of pen, and then store the various inks and
electronics necessary to drive the pen (as well as a battery) in the
pen itself.  Alternatively, the pen could be tethered, and the
electronics and power be located remote from the pen, and brought to
the pen head via the cable.

   A trackpoint style button could be used to control the
color that is instantaneously being delivered to the pen tip, so as
to allow the user to vary the color on a continuous basis that is
being applied to the work area (e.g. paper).
