Abstract

Abstract A system for successively weighing a plurality of articles, computing the value of each weighed article and printing records of the weight and value of each article having two different modes of operation. In a first operating mode, a stored tare weight for the article container and stored price information are automatically cleared either each time a record is printed or each time a weighed article is removed from the system. The price information may be in the form of either price per unit weight or price per fractional unit weight. In a second operating mode, the price information is restricted to price per unit weight and the stored tare weight and price information are not cleared automatically.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 244 words
A system for weighing, computing and printing records of the weight and value of articles having retail sales and pre-packing modes of operation and comprising, in combination, means for measuring the gross weight of the articles, means for storing a tare weight, means for calculating the net article weight from the measured weight and the stored tare weight, means for storing price information, computer means for computing the value of the weighed article from the net weight and the stored price information, means for supplying price per unit weight information to said price storing means, means for supplying price per fractional unit weight information to said price storing means, means for printing the net weight and the computed value for each weighed article, means for clearing said tare weight storage means and said price information storage means, switch means for selecting one or the other of said modes of operation and having a retail sales setting for enabling said clearing means for automatically clearing said tare weight storing means and said price information storing means after either each time a record is printed or each time a weighed article is removed from the system and having a pre-package setting for inhibiting said price per fractional unit weight supplying means and for inhibiting said clearing means from automatically clearing said tare weight storage means and said price information storage means, and indicator means separate from said switch means for indicating said pre-packaging mode of operation.
Claim 2
Independent Claim 244 words
A system for weighing, computing and printing records of the weight and value of articles having retail sales and pre-packing modes of operation and comprising, in combination, means for measuring the gross weight of the articles, means for storing a tare weight, means for calculating the net article weight from the measured weight and the stored tare weight, means for storing price information, computer means for computing the value of the weighed article from the net weight and the stored price information, means for supplying price per unit weight information to said price storing means, means for supplying price per fractional unit weight information to said price storing means, means for printing the net weight and the computed value for each weighed article, means for clearing said tare weight storage means and said price information storage means, switch means for selecting one or the other of said modes of operation and having a retail sales setting for enabling said clearing means for automatically clearing said tare weight storing means and said price information storing means after either each time a record is printed or each time a weighed article is removed from the system and having a pre-package setting for inhibiting said price per fractional unit weight supplying means and for inhibiting said clearing means from automatically clearing said tare weight storage means and said price information storage means, and indicator means separate from said switch means for indicating said pre-packaging mode of operation.
Claim 3
Dependent Claim 64 words
A system for weighing, computing and printing records of the weight and value of articles, as set forth in claim 1, wherein said clearing means includes means responsive to said printing means printing the net weight and the computed value when said switch means is in said retail sales setting for automatically clearing said tare weight storing means and said price information storing means.
Claim 4
Dependent Claim 66 words
A system for weighing, computing and printing records of the weight and value of articles, as set forth in claim 1, wherein said clearing means includes means responsive to the removal of an article being weighed from said gross weight measuring means when said switch means is in said retail sales setting for automatically clearing said tare weight storing means and said price information storing means.
