PROBLEM TO BE SOLVED: To provide a printed circuit board processing machine, capable of preventing or reducing the generation of a rocking vibration by a small-sized active mass damper. SOLUTION: This printed circuit board processing machine is provided with the active mass damper 20 composed of a support device removably supporting a plumb 21 in the horizontal direction and a plumb driving device for driving the plumb 21. The active mass damper 20 is disposed so that the moving direction of the plumb 21 is parallel to the moving direction of a table, and the standby position of the plumb 21 is previously fixed. In moving the table, the plumb 21 is moved in the same direction as the table during the movement of the table, and the plumb 21 is positioned in the standby position in a timing to stop the table, whereby some or all of inertia force of the table generated in stopping the table is canceled by the inertia force of the plumb 21.
