Abstract
A control arrangement for an automatic vending machine includes a price memory device for preliminarily storing selling prices of commodities, a coin signal output section for outputting coin signals upon insertion of coils, a sum calculating device for calculating a sum of inserted coins in response to the coin signals, a difference calculating device for calculating a difference between the sum of the inserted coins and the selling price, a device for calculating the required number of coins for change by dividing the difference by the sum of coins of the same denomination, and a device for judging vendibility at the selling price based on whether or not the required number of coins for the change is present. In this way, the vendibility of all commodities may be determined according to their selling prices without successively subtracting the value of change to paid out for each increment of selling price, and prior to the actual vending of the commodity.
