PROBLEM TO BE SOLVED: To obtain a vending machine for improving working efficiency in a compressor. SOLUTION: The vending machine comprises: evaporators 11, 21 that are individually arranged at a left chamber 10 and a middle chamber 20, respectively; and electronic expansion valves 63a, 63b that are individually connected to respective evaporators 11, 21, thus controlling temperature in the left chamber 10 and in the middle chamber 20 to a specific temperature range by operating the respective evaporators 11, 21. In the vending machine, the flow rate of the refrigerant flowing to the evaporator 21 in the middle chamber 20 connected to the electronic expansion valve 64b is adjusted, thus allowing the working time in the evaporator 21 in the middle chamber 20 to coincide with that of the evaporator 11 in the left chamber 10.
