ABSTRACT:
A controller for a vending machine capable of selecting a mode in which the machine is made possible to sell commodities even if change lacks. If a forced acceptance switch sets a forced acceptance mode, put-in coins are accepted even if no change can be paid. When the sum of the put-in coins arrives at a predetermined set selling price, the controller generates a selling enable signal. If the machine sells a commodity in response to the selling enable signal, it pays out change in the range of the sum in which change can be paid or within the sum of the coins remaining in change coin tubes. In this case, if the coins remaining in the change coin tubes do not satisfy the required sum of change, the overall sum of change is not paid out, but a user of the machine can get a desired commodity.
