articles to purchase at the input section, and depresses a
button to start, the article code is read by the scanner, and
supplied to the cash register. The CPU stores the received
article code in RAM, reads out reference weight data to
article code from the article data table stored in RAM and
temporarily stores the readout data. The weigh scale weighs
the article on the entry conveyor and supplies the measured
weight data to the cash register, which is temporarily stored
in the RAM. This measured weight data is compared with
reference weight data contained in the stored article data,
and if the actual data is close to the reference data, the CPU
identifies the article whose article code is read with the
article put on the entry conveyor, and supplies a drive start
instruction to the conveyor controller to start the operation
of the entry conveyor so that the article on the entry
conveyor is conveyed towards the outfeed conveyor. If the
actual weight is not close to the reference weight, the CPU
issues an instruction to remove the article from the entry
conveyor which stands still without being operated. Since the
entry conveyor and the outfeed conveyor are not driven at all
times, the consumed electric power can be reduced. Further
