Abstract
A weight checking apparatus is provided to prevent items that have not been properly checked from slipping through the weight checker. A weight checker includes a weight conveyor, a loading sensor, a weighing portion, a weighing conveyor weight change monitoring means, an item weight calculation means, and a controller. The loading sensor detects the loading of an item on the weighing conveyor. The weighing portion detects the weight of the weighing conveyor. The controller switches between the weighing conveyor weight change monitoring process and the item weight calculation process based on a detection signal from the loading sensor. The weighing conveyor weight change monitoring process monitors a change in the weight value of the weighing conveyor. The item weight calculation process calculates the weight of the item from the weight value detected by the weighing portion.
