Bar Code Interposer Assembly

      A bar code interposer assembly is described for installation
and support of the active interposer element on impact printers which
print fully formed characters.

      The active interposers element (1) is made of Kapton (du Pont)
film and must be periodically replaced by the customer.  A "U" shaped
frame (2) shown in Figure 1 is made of thin gauge stainless steel and
provides a reliable and convenient means for inserting and supporting
the active interposer element (1) in position especially on line
printers having a narrow throat opening.  A mounting surface for the
active element is provided in the overlapping area (3) between the
frame (2) and the interposer element (1).  A double-sided
pressure-sensitive adhesive strip comes fastened in place on each
interposer element for attachment and removal of the interposer
element to the mounting surface of the frame.

      Since the attachment is made on the hammer side of frame (2)
paper snagging on the mounting edge of the interposer element is
eliminated since the paper passes on the opposite side of frame (2).
Side clearances (4) are provided on the right and left ends of the
interposer element (1) to ensure free flexing of the moving end of
the interposer element.

      The flexural length (5) must always exceed .2 inches, however,
the preferred length is 1.0 inch.  This results in a small, simple
and low-cost replaceable interposer element. The strip has a width
