ABSTRACT:
A drink dispenser includes a continuous supply/stop button that requests a sale of a drink to be suspended when it is pressed during the sale and further requests a drink to be continuously supplied when it is pressed while no drink is being sold, and a mode switch for changing between enabled and disabled states of the continuous supply/stop button. When the continuous supply/stop button is pressed during the sale of a drink, the process is ended if the mode switch is on. Alternatively, when the continuous supply/stop button is pressed while no drink is being sold, the process is ended if the mode switch is on. In the drink dispenser, turning the mode switch on can invalidate a request from the continuous supply/stop button to prevent any inconveniences caused by any improper operation of the button.
