conveyor means for conveying the article whose article
code is read by said reading means;
weighing means for measuring a weight of the article on
said conveyor means before the article is conveyed by said

processing means including:
means for obtaining reference weight data of the
article corresponding to the article whose article code was
read by said reading means; and
means for:
comparing the obtained reference weight data with
the measured weight data produced by said weighing means,
producing a confirmation signal when the reference
weight data substantially equals the measured weight data, and
performing a sales processing for the article whose
article code is read by said reading means only after
production of said confirmation signal indicating that the
