Self-Adjusting Printer Ribbon Shield
Disclosed is a snap-on-printer ribbon shield which self-adjusts to provide a
consistent shield-to-print head ribbon path clearance gap.
Fig. 1 shows that the ribbon shield consists of a plastic bracket 1, to which
spring steel shield 2 is attached by one end 3, the other end 4 remaining free to
move. In the middle of shield is a dimple 5. Bracket 1 is provided with two snap
latch arms 6, one on each side.
Fig. 2 shows that, when the ribbon guide is installed, dimple 5 bears against
printhead 7. Thus, regardless of the variable position of the print head due to
tolerance build up, shield 2 is consistently positioned to provide clearance gap 8
for the passage of ribbon 9.
Referring to Fig. 3, it is readily seen that as ribbon shield 1 is brought up into
position under print head 7, due to the shape of snap latch arms 6, they snap

that by applying finger pressure at points "P", the shield may be unlatched and
