Macchina di erogazione di una bevanda

A beverage dispensing machine has an outlet device for dispensing a beverage and a movable support for supporting a container. The movable support movably supports the beverage dispensing machine at least from a first small container position at least partially placed below the outlet device for receiving the beverage in a small container resting on the movable support to a second large container position moved away from below the outlet device for positioning a large container below the outlet device. A cam device guides rotation of the movable support between the first small container position and the second large container position, and vice versa. The first small container position and the second large container position are stable positions separated from each other by at least one unstable position which, without external forces, causes the movable support to return to a closest stable position between the first small container position and the second large container position.
