摘要
An off-scale item sensing apparatus and method which uses a light beam around a portion of the periphery of a weigh plate. The system includes a source for producing a light beam, a plurality of mirrors for directing the light beam along a path around a periphery of the weigh plate, a detector for receiving the light beam, and an alarm coupled to the detector for alerting an operator when the item is placed in the path of the light beam.
