Abstract: PURPOSE: A commodity vending machine is provided to enable a lodging facility's customers to directly select and use a commodity and to instantly pay for the commodity. CONSTITUTION: A commodity vending machine is composed of insertion, verification, selection, and collection. A user inserts paper money into an insert slot, a controller determines whether the paper money has been inserted, and if the paper money is inserted, the inserted paper money is identified(S101,S102). If the inserted paper money is satisfactory, the inserted amount is confirmed and the various products which can be purchased by that amount is displayed(S103,S105,S106). If the inserted paper money is not in satisfactory condition and determined to be counterfeit paper money, the money is returned to the user(S104). Once a commodity selection signal has been issued from a selection button, a selected commodity's door is opened(S107,S109). If a commodity selection signal has not been issued, the machine determines whether a cancellation signal has been issued by a cancellation button(S108). If the cancellation button has been pressed, the inserted money is returned to the user(S104). If it is determined that the cancellation signal has not been issued, the selective commodities are continued to be displayed(S106). Once the machine detects the opening of a door, it collects the money and concludes the controller's operations(S110,S112,S113). If the machine does not detect the opening of a door, an operation error sign is displayed, the inserted money is returned to the user, and the controller's operations are concluded(S110,S111,S104).
