Abstract

A system for processing articles selected for purchase and bearing distinct identification codes comprises, in one version: (a) a code reader for generating an output signal indicative of such article identification code; (b) a conveyor for receipt and transport of such article; (c) an entrance sentry for defining an inlet to a secured zone extending along a portion of the conveyor and for generating an output signal indicative of entry of the article into the secured zone and of a measurable characteristic of the article; and (d) a controller for selective movement of the conveyor in respective article acceptance and article rejection senses. The controller is operable in several respects, namely, for storage, for each of a plurality of such articles, of a signal indicative of a predetermined value of the measurable article characteristic correlated with such article identification code, for response to the code reader output signal for comparison of such stored signal with the output signal of the sentry, and for operation of the conveyor selectively in response to the results of such comparison.

8. The system claimed in claim 7 wherein said control means is inclusive of storage means and is operable for compiling in such storage means, for each of a plurality of such articles, a signal indicative of a predetermined value of said first article characteristic correlated with article identification code by processing of said output signals of said code reader means and said sentry means.

9. A system for processing articles selected for purchase and bearing distinct identification codes, said system comprising:

(a) first code reader means for generating an output signal indicative of such article identification code;

(b) conveyor means for receipt and transport of such article;

(c) means defining a secured zone extending along a portion of said conveyor means;

(d) second code reader means for generating an output signal indicative of such article identification code of articles in said secured zone;

(e) control means for selective movement of said conveyor means in respective article acceptance and article rejections senses, said control means being operable for comparing said output signal of said first code reader means with said output signal of said second code reader means and for operation of said conveyor means selectively in response to the results of such comparison; and

(f) EAS detection means for determining whether or not an article in said security zone is EAS-tagged, said control means being further operable for storing indication, for each of a plurality of such articles, of whether or not such article should be EAC-tagged and for operating said conveyor means selectively in response to such stored indication and determination.

10. The system claimed in claim 9 wherein said system further includes sensing means for providing an output signal indicative of a measurable characteristic of said article and wherein said control means is operable for compiling a store, for each of a plurality of such articles, of a signal indicative of a predetermining value of said article characteristic correlated with article identification code by processing of said output signals of said code reader means and said sentry means, said control means being further operable for comparison of such stored signal for an article with said output signal of said sensing means and for operating said conveyor means selectively in response to the results of such comparison of such stored and measured article characteristic output signals.
