Ink Ribbon Shield

      This article describes an ink ribbon shield that has a simple
rectangular shape without any folds for ink ribbon pass stability, is
installed easily and firmly, and can be made at very low cost.  This
ink ribbon shield is used on a ribbon cartridge for dot-impact
document printers, as shown in Fig. 1.

      This ink ribbon shield has no special brackets for installation
to an ink ribbon cartridge, and is made of durable plastic film.
Guides for preventing a ribbon from slipping off are on the cartridge
case.  Therefore, the shape of the ribbon shield can be simple.  As
shown in Fig. 2, the outline of this ink ribbon shield is a
simply-pierced rectangle.  The L-shaped hole at one side of the
shield is for avoiding mis-installation to the cartridge case, and
mates with the L-shaped projection on the cartridge.  Installation to
the ribbon cartridge is easy, just hanging the holes of the ribbon
shield on the hooks at both sides of the ribbon cartridge.  Fig. 3
shows a sectional view of the hook of the ribbon cartridge.
