In this state, the high-temperature plate-like body G, which has been formed into a predetermined shape through a weighing process using the weighing scale 96, a melting process using the melting unit 16 and the means 97, and a forming process using the molding unit 98, is removed by the operator. It is placed on the water-cooled turntable 7 of the positioning means 2.

In this case, the plate-shaped body G is always placed on the water-cooled turntable 7 with a constant directionality due to the relationship with the engraving process to be described later. For convenience of explanation, O1 is marked on one side of the surface of the plate-shaped body G, and X is marked on the other side.

The plate-shaped body G placed on the water-cooled turntable 7 comes into contact with the belt 13 of the transfer mechanism 9 as it rotates counterclockwise.

At this time, due to the frictional force accompanying the rotation of the water-cooled turntable 7 acting on the bottom surface of the plate-shaped body G, the plate-shaped body G
At the same time, due to the circumferential movement of the belt 13, it slides in the Y direction in FIG. 2 and is transferred onto the transfer plate 18 of the positioning mechanism 17.

As shown in FIG. 2, the plate-shaped body G that has slid on the roller 19 of the transfer plate 18 comes into contact with the stopper 20 and stops once, and at the same time, the actuator 23 of the switch 22 is actuated to output an electric signal. is sent to the plunger 21, and the stopper 20
