PROBLEM TO BE SOLVED: To improve the heat exchanger efficiency of a cooled heat exchanger of an automatic vending machine for cooling a plurality of merchandise storages by distributing cold air ducts from one heat of cooling exchanger. SOLUTION: This automatic vending machine is provided with a cold air suction duct 54 whose one part is opened to a merchandise storage 40c in which merchandise is stored and whose other part is opened to a cooling chamber 50 in which a heat of cooling exchanger 81 is stored for supplying air from the merchandise storage 40c to the heat of cooling exchanger 81; and a cold air delivery duct 55 whose one part is opened to a cooling chamber 50 and whose other part is opened to a plurality of merchandise storages 40c for supplying air cooled by the heat of cooling exchanger 81 to a plurality of merchandise storages, wherein the cooled heat exchanger is arranged at the central position of the vertical direction of the cooling chamber, and channels 83 and 85 are formed at the upper and the lower parts of the heat of cooling exchanger 81, and in-storage air is made to flow from the lower channel 83 to the upper channels 85, so that the efficiency of the heat of cooling exchanger 81 can be increased.
