The information of sales items is transmitted from a cash register 1 to a sensing device 2 and stored in a sales items memory 26. In the sensing device 2, a commodities information memory 25 stores the information relating to a nominal weight of each commodity as well as a nominal weight of a package. A weight sensor 24 measures an actual overall weight of all of the sales items including the package. A controller 23 compares the measured overall weight with a sum of their nominal weight values, to detect any error in the packing operation.
