Data gathering system interface
First Claim
1. A data gathering system for use in a checkout counter to determine information relating to products to be purchased and to provide such information to a cash register system, comprising:
- optical scanning means supported on a subplatter for reading coded labels on products presented to said data gathering system, said optical scanning means including a bar code decoder circuit for decoding scan signals to provide coded label data, a scanner microprocessor for correlating and supplying coded label data, and scanner memory means for storing control software for use by said scanner microprocessor,scale means supported within said checkout counter for determining weights of said products, said scale means including said subplatter located below the upper surface of said checkout counter, said scale means capable of supplying weight data to said bar code decoder circuit of said optical scanning means, anda common interface circuit, responsive to both said scale means and said optical scanning means, for providing weight data and coded label data to said cash register system, wherein said scanner microprocessor of said optical scanning means is capable of supplying said coded label data to said common interface circuit, and said scale means is capable of supplying said weight data to said common interface circuit via said scanner microprocessor without alteration.

Abstract
A data gathering system for use in a checkout counter to determine information relating to products to be purchased and to provide such information to a cash register system includes a scale supported within the checkout counter for determining weights of products presented to the data gathering system. The scale includes a subplatter located below the upper surface of the checkout counter. An optical scanning arrangement is supported on the subplatter for reading coded labels on the products. A common interface circuit is responsive to both the scale and the optical scanning arrangement, for providing weight data and coded label data to the cash register system.
