PROBLEM TO BE SOLVED: To provide an automatic vending machine which can switch a temperature controlled area excellently. SOLUTION: An air circulation path is changed in two ways at the time of cooling or heating by placing an air blower 12 arranged at the upstream outlet 10a of a duct AD and an air blower 13 arranged at the downstream outlet 10b selectively in operation, so that the temperature controlled area can be switched between 'whole' and 'partial'. Thus, the temperature controlled area can be switched at the time of cooling or heating through the selective operation of the upstream air blower 12 and downstream air blower 13, so problems of a fault and an operation defect which are possibly caused when a dumper is opened and closed repeatedly like in a conventional machine which switches the temperature controlled area by using a dumper mechanism area all eliminated to switch the temperature controlled area stably for a long period as expected.
