Abstract From the Canadian patent

The invention is an automatic vending machine which measures the weight of a retaining vessel which contains a certain amount of a commodity to be sold. The weight of the vessel before and after the partial or complete removal of the commodity is measured and a numerical value corresponding to the quantity of the commodity thus removed is fed out as an electrical signal. A computer then calculates the price according to the weight of commodity removed and the unit price and the price is recorded on a shopping card or the like. The invention reduces space, manpower and time n supermarkets and similar stores.
