ABSTRACT:
A skid plate retained below an electronic register module includes a plurality of cantilevered spring fingers formed by parallel pairs of slots in the skid plate. Each cantilevered spring finger includes a frusto-conical button which bears against a back plate in a housing during installation of the electronic register module therein. A rear end of the back plate includes a pair of mouse holes into which a rear pair of frusto-conical buttons engage during an intermediate stage of inserting the electronic register module into the housing. This engagement establishes the correct side-to-side positioning of the rear end of the electronic register module. A front cantilevered spring finger and its associated frusto-conical button resiliently urge the front of the electronic register module upward during substantially all stages of installation and in the operational position thereof. When the electronic register module is advanced further into the housing, the rear pair of frusto-conical buttons ride up onto the surface of the back plate thereby providing an upward resilient force for securing the electronic register module into its operational position. At least one depression is provided in the back plate for receiving a frusto-conical button at the operational position of the electronic register module.
