    • PROBLEM TO BE SOLVED: To provide a vending machine having a plurality of commodity storages, consuming little power, reducing the frequency of starting a compressor with high reliability, and having an excellent heating property even at low peripheral temperatures. SOLUTION: This vending machine having the plurality of commodity storages to selectively cool or heat each commodity storage by an operation mode of the cooling/heating includes: the compressor; a condenser provided outside the storage; an expansion means; a plurality of evaporators provided inside the storages; heat exchangers provided inside the storages; heaters provided inside the storages; internal temperature detection means each detecting an internal temperature; and a control means controlling them by thermocycle operation. When the temperature inside the commodity storage performing heating operation at cooling/heating simultaneous operation becomes a thermo-operation start temperature, the control means performs heat pump operation until the temperature inside the commodity storage performing the heating operation when the internal temperature of the commodity storage performing cooling operation is the thermo-start temperature or above becomes a thermo-operation stop temperature.
