Abstract: A system for processing articles selected for purchase and bearing an identification code, comprises a code reader for generating output signals indicative of the article identification codes, a first storage unit for storage, for each of the articles, of a signal indicative of a price for the article correlated with the article identification, a second storage unit selectively operable for temporary storage of a signal indicative of a price for an article selected for purchase correlated with the article identification, and a control unit operable on receipt of the code reader output signals for fetching the price-indicative signal from the first storage unit, selectively operable on failure of the price fetching from the first storage unit for accepting operator input of a price-indicative signal for the article and storing the operator input signal in the second storage unit, and for fetching the price-indicative signal for the article from the second storage unit until such time as a price-indicative sign

Abstract: A system of the so-called "operator-unassisted" type, for processing articles selected for purchase and bearing an identification code, includes a code reader generating output signals indicative of the article identification codes, a sensor generating output signals indicative of measurable characteristics of the articles, a memory for storage, for each of the articles, of a signal indicative of the measurable characteristic thereof correlated with the article identification code, an article rejector for rejecting the selection of an article for purchase on failure of correspondence of the sensor output signal and the corresponding stored measurable characteristic signal and a control unit operable selectively on such rejection of the article purchase selection for substituting the output signal generated by the sensor for the stored measurable characteristic signal. The control unit effectively introduces an "override capacity" to heretofore known systems.

Abstract: A checkout station for checking out articles selected for purchase and bearing UPC codes includes an island for checkout including a first checkout module, having a first UPC scanner and a first conveyor leading from the first scanner to a first bagging area. A first customer passageway extends lengthwise along one side of the first conveyor. A cashier station is adjacent a second side of the first conveyor. A second checkout module, having a second UPC scanner and a second conveyor leading from the second scanner to a second bagging area and having one side adjacent the cashier station. A second customer passageway extends lengthwise along the other side of the second conveyor. Checkout is practiced by a customer scanning article UPC and an operator (cashier) processing payment, increasing throughput.

Abstract: An operator-unattended checkout system for processing articles selected for purchase and of first type bearing supplier-applied UPC indication and of second type not having supplier-applied UPC indication includes a reader for generating output signals indicative of article UPC indication where present on articles, a first processing part operable without customer input for using the reader output signals for determining first type article price and generating output signals indicative thereof, a customer-interactive display unit for use through customer input thereto for directing system operation selectively from such first processing part operation to the computation of second type article price, a scale for determining article weight and generating output signals indicative of determined article weight, and a second processing part operable on customer input to the display unit for using the scale output signals for generating ouput signals indicative of second type article price.

Abstract: Apparatus for providing price indication of articles selected for purchase prior to actual purchase embodies a system having a reader for reading article UPC indication and generating output signals indicative thereof, a comparator for receipt of the reader output signals and for providing at least first and second output signals upon respective determinations that such received signals are indicative of an article retailed by bulk weight pricing or an article retailed per piece pricing, a scale accessible to a customer for weighing the articles and generating output signals indicative of the weight thereof, a numeric entry unit accessible to a customer for entering the numbers of pieces of the selected articles and generating output signals indicative of such entered numbers, and a display accessible to the customer and responsive to the first and second comparator output signals respectively to provide indication to the customer for usage of the scale or the numeric entry unit.

Abstract: A system is provided for the operator-unassisted checkout of articles, inclusive of bulk articles, typically of the nature of produce or the like, wherein supermarket personnel or a customer applies a UPC label to the bulk articles upon selection, as distinguished from the normal instances wherein the article bears a "source-applied" UPC indication, e.g., as in the case of source-packaged goods. Price computation is effected for the bulk articles by scanning of the UPC indication and use of price per unit weight or price per piece derived from storage responsively to the scanning. The article measured weight or the numbers of the article are used respectively in computation of price for the selected bulk article.

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.

Abstract: A system is provided for the checkout of articles selected for purchase by consumers, comprising a code reader for reading an identification code on such articles and generating an output signal indicative of such code reading, a conveyor unit for receiving and transporting the articles, first and second bagging areas served by the conveyor unit, a channeling member operable for placing the conveyor unit selectively in communication with one or the other of the bagging areas, and switches operable by the consumers for use of the system. A controller is responsive to the code reader output signals and the switches for operation of the channeling member. The switches are operable separately by first and second customers respectively at the completion of first customer usage of the conveyor units and prior to use of the conveyor unit by the second customer.

Abstract: The check-out counters for use in a supermarket, or the like, are provided with a laser scanner for reading the UPC labels on the individual products presented to it by each customer. The counters are also provided with transport belts or conveyors controlled by a central processor which, in turn, is supplied with information from a weigh scale under the input conveyor and from optical curtain devics at strategic locations along the belts and in a bagging area. The outfeed conveyor operates through a tunnel such that a customer cannot reach a product being conveyed therethrough. An opticl curtain disposed at the entry to the tunnel is broken by passage of an article into the tunnel and also by a customer reaching into the tunnel. Products are conveyed to the bagging area if (1) the actual weight of the product as determined by the scale corresponds to the anticipated weight obtained from a memory bank based upon the product UPC label identification and (2) none of various other events have occurred.
