ABSTRACT:
A vending machine capable of coping with changes in the kinds of vendible articles and a vend price in a very simple manner without modifying the coin control circuitry. The vender includes a plurality of switches and the vend price can be easily preset by suitably opening and closing these switches. Upon depression of a desired article selection switch of the vender, a set vend price signal corresponding to this switch is supplied to coin control circuitry in the form of a binary signal. The coin control circuitry compares the set vend price signal with amount of inserted coins and, when vending is possible, supplies a vend signal to the vender via a single line. The vender dispenses the selected article in response to depression of the article selection switch and receipt of the vend signal.
