Change making system










Image Number 8 for United States Patent #4462512.

A change making system having circuitry for sensing the availability of coins for making change in at least two change tubes containing coins of different denominations, the coin tubes being part of a money handler in a vendor. A memory has stored therein, for each of a number of coin availabilities, a plurality of coin combinations equalling various amounts of change. A microprocessor determines the amount of change due the customer and retrieves from memory a coin combination, if any, stored therein which corresponds to the amount of change due and the particular availability of coins in the change tubes. If there is such a combination, it allows the vend. A method of the change making system is also disclosed.
