Sales data processing system
First Claim
1. A sales data processing system comprising:
- data reading means for reading sales article data previously attached to sales articles;
first weighing scale means for measuring weight of one or a plurality of sales articles whose sales data are to be read out by said data reading means, to produce weight data corresponding to a stable measured value;
second weighing scale means for measuring weight of one or a plurality of sales articles whose sales data have been read out by said data reading means, to produce weight data corresponding to a stable measured value;
first and second memory means for storing weight data from said first and second weighing scales;
third memory means for storing data representing a difference between the weight data derived from said first weighing scale means and the contents in said first memory means when the former contents have varied from the latter contents;
fourth memory means for storing data representing a difference between the weight data derived from said second weighing scale means and the contents in said second memory means when the former contents have varied from the latter contents;
fifth memory means for storing sales data read by said data reading means;
means for comparing the respective differences stored in said third and fourth memory means; and
data processing means for executing the registration of the article data according to the sales data stored in said fifth memory means, when said data processing means detects that the contents of said third and fourth memory means are substantially coincident with each other.

Abstract
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 an initial weighing scale for measuring weight of a plurality of sales articles whose sales data is to be read out, a second weighing scale 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, third and fourth memories for storing variation amounts of weight data derived from the first and second weighing scales when an article is removed from the first weighing scale and is then placed on the second weighing scale 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.
