ABSTRACT:
A checkout system for processing purchased merchandise items includes a checkout counter in which is located a scanning assembly for scanning a coded label on the purchased item to produce data signals identifying the item purchased, a display member on the counter for displaying the price of the merchandise item purchased, an indicator light and a tone generator located in the display member, a back office processor for obtaining the price of the merchandise item scanned from a price look-up table using the data signals as an address and a data terminal device for printing the price of the items scanned on a record member. Processing means located in the scanning assembly and the display member cycles the operation of the tone generates when the price of the item scanned is not found in the table and cycles the operation of the indicator light whenever a malfunction occurs in the operation of the terminal. In both cases, the operation of the scanning means is disabled.
