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.
