Apparatus to establish cover seam separation integrity in a fiscal printer

Relative to the seam separation between covers/lids and bases: a solution is needed to

maintain the cover-to-base seam connection in a fiscal printer, thereby thwarting any

undo probing into internal components. Ideally, this solution should also be comprised

of attributes that are easy of manufacture.

There are currently no known solutions relevant to that being described here. The disclosed solution incorporates the following components and features:
• A swinging arm with a manufacturing tolerance take-up wedge attached to the

• A flexible receptacle on the base, which, once the swing arm wedge is

positioned, can be locked in place in order to connect the cover to the base with

a tight seam (Figure 1)
• A lid or cover fitted to a base such that the lid has a pivoting arm with a distal end

that has a wedge shape; the wedge shape pivots into a receptacle on the base
• Flexible receptacle on the base, such that the wedge shape of the pivot arm

flexes the receptacle as it is pivoted into place
• The receptacle holds the lid down by holding the retaining the wedge shaped

distal end of the pivoting arm.

o The distance from the wedge to the edge of the flexible receptacle

determines how much the receptacle will flex open.

o The distance from the wedge to the receptacle edge is determined by

dimensions and tolerances that make up the lid-to-base connection.
• The receptacle ca...
