PURPOSE:To simplify operational labor in the case of mass buying and to shorten vending time by repeating a vending operation for each cup of coffee just for the number of cups to be simultaneously bought stored in a storage means. CONSTITUTION:A number A=1 of cups to be simultaneously bought is initially set. Next, the value A is incremented/decremented corresponding to whether a pressed button is a cup number plus button 14 or a cup number minus button 15, and the number A of cups to be simultaneously brought is displayed on a mass buying cup number display 17. When a vending button 16 is turned on, the present number A of cups to be simultaneously brought is set to a counter 11a. Next, the extracting operation of coffee is performed with the amount of raw materials and the quantity of hot water just for one cup, and coffee beverage is poured to a decanter. Afterwards, the counter value A is decremented just for '1' and the remaining number of times of vending operation is displayed. Then, lees from the production of coffee is discarded, and the vending operation is repeated until the A is turned to '0'. In any case excepting for batch buying, the vending button 16 is immediately turned on corresponding to the initial value A=1. |
