PROBLEM TO BE SOLVED: To easily supply syrup being a raw material for drink in a post-mix method or a premix method by a method wherein a control device is provided to control a solenoid valve in such a manner that if a sensing part senses a shortage of raw material for drink, it closes a feed passage, and if the sensing part senses the presence of the raw material, it opens the passage. SOLUTION: If syrup is present in a syrup conduit 54, a control device 58 senses a syrup present state based on a sensing signal of a sensing part 57. Under such conditions, if a drink supply signal is inputted from a switch 59, the device 58 energizes a solenoid valve 51 to open a syrup conduit 54 and a carbonated water conduit, and hence syrup A and carbonated water is supplied to a multi-valve 34 so as to be mixed and poured into a cup 5. If the syrup is in short supply and the sensing part 57 senses the shortage, the device 58 de-energizes the valve 51, and hence even if the switch 59 is turned on, the valve 51 is not turned on. However, other drinks in a syrup present state are uninterrupedly maintained in suppliable and salable state.
