PURPOSE:To prevent any stain as well as any wear and tear of a stopper, and reduce the shift and defective contact of parts by providing a sintering table with penetrating holes, and sucking and fixing a bead glass through the penetrating holes by means of a vacuum device. CONSTITUTION:The upper surface of a sintering table 1 is provided with a concave part 2, on which a bead glass is placed. The table 1 is provided with two penetrating holes 4 and 5 which open into the concave part 2 and protrude through the back surface of the table 1. Ends of the holes 4 and 5 are connected to pipes 6 and 7, which are connected to a vacuum device. A stopper 8, one end of which is connected to an air cylinder 9 connected to the vacuum device, is attached to one side surface of the table 1 so that it is vertically movable. When the stopper 8 moves upward, the other end of the stopper 8 protrudes above the part 2 so as to make the bead glass to be positioned. As a result, any stain of the stopper 8 can be prevented, and any stain and defective separation of the bead glass can be prevented.
