PROBLEM TO BE SOLVED: To suppress heat transfer between adjoining commodity storage chambers in an automatic vending machine having the storage partitioned into the plurality of commodity storage chambers mixed with hot chambers and cold chambers. SOLUTION: This automatic vending machine has the storage in a body case 1 partitioned into the plurality of commodity storage chambers by partition walls 3, drives cooling/heating units by setting a sales mode to hot or cold for every commodity storage chamber, and has the hot chambers and the cold chambers mixed in the single storage. The inner door of this machine comprises a thin box-shape outer frame and a door board facing to the storage. The door board of the inner door is partitioned corresponding to the respective commodity storage chambers and the respective partitioned door boards 821, 822, and 832 are connected by insulating members 80. This constitution can prevent the heat transfer between the partitioned door boards and suppress the heat transfer to the adjoining commodity storage chambers. COPYRIGHT: (C)2004,JPO
