A drink dispenser which permits an advance order for a drink to be made even during the sale of another drink, and which is capable of selling drinks reliably. When any one of drink sale buttons (5a-5d) is pressed while a drink is being sold with any one of drink discharge valve relays (X1-X4) opened, a CPU (1) stores this sale order in a RAM (3). When the present drink sale has finished, the time counting by an interval timer (not shown) connected to the CPU (1) is started, and, when a predetermined period of time has thereafter elapsed, a drink in accordance with the sale order stored in the RAM (3) is sold by opening a corresponding valve. This enables an advance order for a drink to be made even during the sale of another drink, and preparation time for the sale of a preengaged drink to be taken. Therefore, drinks can be sold reliably.
