Abstract

This invention enables a printer to highlight in various colors selected parts of a text. It can be used as the base for an electronic scanner used in applications such as a system copier or a facsimile machine. Because of its ability to move and register paper so accurately, it can also be used as the base for a serial printer or a pen plotter. It is unique because it does so without adding additional cost to the base printer and it does not slow the speed of black and white printing.

Modular Printer Highlighter

       This invention enables a printer to highlight in various
colors selected parts of a text.  It can be used as the base for an
electronic scanner used in applications such as a system copier or a
facsimile machine.  Because of its ability to move and register paper
so accurately, it can also be used as the base for a serial printer
or a pen plotter.  It is unique because it does so without adding
additional cost to the base printer and it does not slow the speed of
black and white printing.

      The additional highlight module shown in the figure is placed
under the base of a printer (not shown) so the paper exit 1 of the
highlight module aligns with the paper input slot of the base of the
printer.  The paper 2 is picked from the highlighter paper tray 3 and
fed incrementally by pick roller 3a to the rear of the machine and
deflected up and turned 180 degrees back to the front of the machine
by the deflector 4.  The paper is then stopped and reversed, the
moving being by driver rollers 4a.  The paper is then moved toward
the rear of the machine, top edge first, to the area of the first
highlighting.  The paper is stopped long enough to have the
highlighter engine 5 move across the paper perpendicular to the
direction of paper movement and apply the appropriate color.  Only
one highlighter engine is shown, but additional engines of different
color may be added.  The paper may be moved incrementally for
successive highlight...
