    • PROBLEM TO BE SOLVED: To solve a problem that the deviation or the inclination of an optical axis of a plurality of optical surfaces does not satisfy the required precision when an optical device is formed by a conventional forming apparatus.
      SOLUTION: This forming apparatus is provided with a lower die 11 on which a 1st forming surface 11a is formed, an upper die 18 on which a 2nd forming surface 18a opposed to the 1st forming surface 11a of the lower die 11 is formed, a heating means for heating glass gob W held between the 1st forming surface 11a of the lower die 11 and the 2nd forming surface 18a of the upper die 18 to a prescribed temperature, a drum mold 12 to which the lower die 11 is integrally connected and engaged with the the upper die 18 to slide in the direction opposed to the lower die 11, a main press cylinder 15 for moving the drum mold 12 together with the lower die 11 along the direction opposed to the upper die 18 and a subsidiary press cylinder 19 for moving the upper die 18 along the direction opposed to the lower die 11.

    • PROBLEM TO BE SOLVED: To provide a lens molding mold for molding a lens which can be attached to a lens holder without carrying out burr removal processing after molding, a lens molding method, the lens, and a pickup device.
      SOLUTION: The lens molding mold has a first mold for molding the first lens surface of the lens and a second mold for molding the second lens surface of the lens. In the contact face of at least one of the first and second molds which contacts with the other mold part, an air vent groove is formed. At least at the periphery of the air vent groove of the periphery forming surface forming the cylindrical surface of the lens of the mold having the air vent groove, a convex surface for forming a recess accommodating burrs by the air vent groove is formed.
