      A plotter is provided for cutting complex shapes from paper,
plastic or other sheet material.

be made to extend its capability from drawing to shaping.  Plotters
have obvious advantages over hand drawing in repeatability, accuracy

a special rotating bit 20 that has a cutting surface optimized to cut
paper at a 90-degree angle.  The bit 20 is rotated by a miniature
high-speed motor 22 which is in turn powered by, preferably, a
standard AAA rechargeable nickel-cadmium battery 24.  The battery 24,
motor 22 and bit 20 are housed in a st...
