<p>A coin-operated vending machine includes a multi-stage binary counter for totalizing the value of coinage inserted into the machine. Numerical outputs of the counter are connected to price setting switches for determining the prices at which commodities are to be vended and the totalized value of coinage inserted is registered by the numerical outputs. Change is given when the value of the inserted coinage exceeds that of the selected commodity.</p> |
