PROBLEM TO BE SOLVED: To provide an inexpensive press machine which is used for blanking, swaging and die forging and is designed to permit the use of a fine guide shaft by diminishing a rotational moment generated in a slide plate so supporting a movable die of the press machine.SOLUTION: Drive shafts 61a and 61b of drive sources 60a and 60b of the press machine form a planar polygon peaking at thrust points (engaging parts) 62a and 62b at which the drive shafts thrust the slide plate 40 at these thrust points. Displacement measuring means 50a and 50b are disposed near these engaging parts, and while the displacement of the engaging parts is measured in mid-way of molding, the drive sources are controlled by control means and the press machine is operated while the planar polygon is maintained horizontally.
