COFFEE MACHINE

The present invention relates to a coffee machine equipped with a grinder that grinds coffee beans, and a mechanism that reduces ground beans on an inner peripheral wall of a chute. A hammer includes a striking member that abuts against a chute by an elastic force in an initial state, and a second holding member that sandwiches and holds a cup with the first holding member by the elastic force, and enters a striking preparation state in which the striking member is temporarily separated from the chute by pivoting from the initial state, the second holding member is disposed at a position where a distance from the first holding member is smaller than a thickness of an peripheral wall of the cup in the initial state, and the striking member applies an impact to the chute when the hammer returns from the striking preparation state to the initial state by the elastic force.
