Abstract
Systems and techniques for scanner scale implementation and operation using a plurality of load cells mounted in a planar arrangement. A plurality of load cells is mounted to a scanner base. The load cells are secured within a mounting chassis in such a way that the load bearing elements of the load cells extend through the protective cover. The mounting chassis and load cells may be mounted to the scanner base. A scanner top plate may be secured to the load cells such that the weight of the scanner top plate and any object placed on the scanner top plate is borne by the load bearing elements of the load cells, part of the weight being borne by the load bearing element of each load cell. Upon presentation of an object for weighing, weight signals generated by the load cells are processed to produce a weight reading for the object.
