A drink vending machine for providing fixed amounts of drinks is basically formed of a sales amount memory device for memorizing amounts of drinks to be sold as an opening duration of an ejection valve; a valve controller for opening the ejection valve by operation of one of the drink sales buttons; and a mode setting device for changing a mode to a setting mode for setting amounts of the drinks to be sold. The vending machine further includes a drink sales halt device, a timer and a sales amount registration device. The drink sales halt device stops ejection of the drink while the drink is ejecting from the ejecting valve by actuation of the sales button in the setting mode. In the setting mode, the timer counts the opening duration of the ejection valve from a time the sales button is pushed to a time the drink sales halt device is actuated. The sales amount registration device stores the counted opening duration of the ejection valve, which is used as the amount of the drink to be sold in response to operation of the sales button in a sales mode.
