Overlay Retention

      This article describes a cover design which provides for
insertion, removal and retention of overlay material within the
cover, utilizing the flexing quality of the overlay material.

      In the design of a portable entry terminal, frequent changes of
various overlay materials to be inserted/removed or retained can be
required.  The development of the flex method of the overlay material
accomplishes all these requirements without using additional clips or
devices and complements the human factors of overlay
insertion/removal and retention by terminal personnel.

      In the drawings, Fig. 1 is a front view of a cover design.
Figs. 2 through 5 are sectional views across A-A of Fig. 1 showing
the steps involved for insertion of the overlay material.  The
curvature of the insertion path permits low force insertion.  Once
the overlay material is seated and retained, a high starting force is
needed to start removal of overlay material past curvature surface B.
