Sales data processing system.

摘要

A sales data processing system reads sales data containing article codes previously attached to sales articles, and executes registration of sales data according to the sales data thus read. The sales data processing system includes a first weighing scale (2) for measuring weight of a plurality of sales articles whose sales data is to be read out, a second weighing scale (3) for measuring weight of a plurality of sales articles whose sales data have been read out, first and second data memories for storing stable weight data from the first and second weighing scales (2 and 3), third and fourth memories for storing variant amounts of weight data derived from the first and second weighing scales (2 and 3) when an article is removed from the first weighing scale (2) and is then placed on the second weighing scale (3) after the sales data of the article is read out, and a data processing unit for executing the registration of the sales data according to the readout sales data when it is detected that the contents in the third and fourth memories are substantially coincident with each other.
