Abstract
An automatic vending machine having a control circuit for controlling the quantity of ice in an ice storage chamber. A signal generating circuit is provided for producing digital signals in response to ice being supplied to, and discharged from, the ice storage chamber. A counting circuit comprising an up-down counter receives the digital signals and adjusts a count value which represents the quantity of ice in the storage chamber. The counter produces an output signal when sufficient ice is available to supply vending needs, but not when the ice quantity falls below a predetermined value. The vending operation is suspended when the counter output signal is not produced.
