A molding material supply device, which is equipped with a clamping rod that can open and close the tablet-shaped molding material for clamping the tablet-shaped molding material at the tip of a swinging arm that can reciprocate nearby, is disposed nearby, and the molding material that is clamped by the clamping rod is installed. Since the preheater is arranged to allow the clamping rod to move in and out while holding the molding material on the rotational path of the material, the molding material supply device, the preheater, and the compression molding machine can be easily connected to each other. This makes the layout more compact. Furthermore, since the tablet-shaped molding material is preheated in the preheater while being held between the clamping rods and then fed to the lower mold of the compression molding machine, the preheating operation can be carried out smoothly. In addition, it becomes possible to quickly and accurately supply the preheated tablet-shaped molding material to the lower die of the compression molding machine, and the molding efficiency of the compression molding machine is improved.
