摘要： A transfer arm holds a plurality of preforms arranged in a single line and simultaneously drops and supplies the preforms downward. A positioning arm has a pair of arm split members split in its widthwise direction. The arm split members have positioning surfaces formed on their contact surfaces to be brought into contact with outer peripheries of the preforms. After the preforms are dropped and supplied from the transfer arm, the arm split members of the positioning arm are opened and closed so that the positioning surfaces are brought into contact with the outer peripheries of the preforms. Thus, the performs are properly positioned.

摘要： In a press molding apparatus for press molding a plurality of glass materials into a plurality of glass optical elements by the use of a pressing mold including upper and lower molds each of which has a plurality of molding surfaces, at least one of the upper and the lower molds is a heat generator within which heat is generated when the heat generator is subjected to a high-frequency induction heating by an induction heating coil. The heat generator having a plurality of shape-processed portions (130) produced by partially processing a shape of the heat generator in order that a temperature distribution of the heat generator is adjusted. The apparatus simultaneously press forms, into the glass optical elements, the glass materials supplied between the molding surfaces of the upper and the lower molds which are subjected to the high-frequency induction heating.
