PROBLEM TO BE SOLVED: To provide a vending machine capable of suppressing temperature variation of goods for sale, easy to handle, and free from increase in the manufacturing cost. SOLUTION: The vending machine comprises an auxiliary heater 5 for heating the air near a goods-cutting out device 3, an auxiliary temperature sensor 6 for measuring the temperature of the air, and a main temperature sensor 9 for measuring the temperature of the ventilation air. Either or both of a main heater 16 and the auxiliary heater 5 are controlled by the main temperature sensor 9, based on the difference between the main air temperature measured and the auxiliary air temperature measured by the auxiliary temperature sensor 6. The main heater 16 is activated, when the main air temperature is lower than a predetermined temperature set value, and when the auxiliary heater 5 is activated, based on the difference between the main and auxiliary air temperatures is greater than a predetermined standard value; and the auxiliary heater 5 is deactivated, when the difference is smaller than the predetermined standard value. Furthermore, heat generation by a solenoid for driving the goods-cutting out device 3 is utilized as the auxiliary heater 5. COPYRIGHT: (C)2006,JPO&NCIPI
