SYSTEMS AND METHODS OF ALTERNATE OPERATION FOR A SCANNER-SCALE HAVING AN ITEM OVERHANG DETECTION SYSTEM

摘要

In a scanner-scale system for passing items through a read zone over a weigh platter of the scanner-scale, the system including an item overhang detection system operable for providing an output upon sensing that an item overhangs beyond an edge of the weigh platter, systems and methods are disclosed for using output from the item overhang detection system to both (1) reduce erroneous weighing upon sensing that an item overhangs beyond an edge of the weigh platter (such as by alerting the operator that an item overhang condition has been detected and thus prompting the operator to reposition the item so as to be fully on scale) and (2) initiate an alternate function of the scanner-scale independent of weighing operation.

1. A method of operating a scanner-scale, comprising the steps of
passing items through a read zone over a weigh platter of the scanner-scale; providing the scanner-scale with an item overhang detection system, wherein the overhang detection system is operable for providing an output upon sensing that an item overhangs beyond an edge of the weigh platter; during weighing operation, using the output from the item overhang detection system to reduce erroneous weighing upon sensing that an item overhangs beyond an edge of the weigh platter; using output from the item overhang detection system for an alternate function of the scanner-scale independent of weighing operation.
