Abstract: Since a second molding surface 103a is separated from the second mold 42 before a first molding surface 102a is completely separated from the first mold 41, in a state difficult to take the unbalanced force, the separating force is applied at the same time on the first and the second molding surfaces 102a and 103a of the substrate 101, it is possible to prevent damage to the substrate 101 at the time of mold release even if the substrate 101 is comparatively thin. Since the mold release is performed with unseparated portions remaining on each of the first and the second molding surfaces 102a and 103a, it is unnecessary to separately provide a step of protecting a first and a second optical surfaces 11d and 12d on the opposite side during the mold release, whereby a precise wafer lens 100 can be produced simply and efficiently.

Abstract: Disclosed is a method for producing a wafer lens, wherein misalignment between a glass substrate and a molding mold is suppressed from occurring. The method for producing a wafer lens comprises: a step wherein, in a first reduced pressure atmosphere, an energy-curable resin is arranged between a glass substrate (11) and a molding mold, and the glass substrate (11) is pressed against the molding mold, while sucking the glass substrate (11) and affixing the molding mold; a step wherein, in a second reduced pressure atmosphere that is under a higher pressure than the first reduced pressure atmosphere, the arrangement of the glass substrate (11) and the molding mold is adjusted while sucking the glass substrate (11) and affixing the molding mold; and a step wherein the energy-curable resin is cured by applying energy to the energy-curable resin, and the glass substrate (11) is released from the molding mold.

Abstract: A disk cartridge ejection mechanism in which a disk cartridge is moved from a loading position where recording and reproducing of information are possible for a medium in the cartridge to a cartridge-removable position where the cartridge can be taken out of an information recording and reproducing apparatus, wherein there are provided a cartridge engagement device that engages with the cartridge when the cartridge moves from the loading position to the cartridge-removable position to prohibit the cartridge to move beyond the cartridge-removable position, a cartridge engagement assistance device that prevents releasing of engagement of the cartridge engagement device for the cartridge, when the cartridge moves to the cartridge-removable position and an assistance releasing device that releases the state wherein a cartridge engagement assistance device that prevents releasing of engagement of the cartridge engagement device, after the cartridge moves from the loading position to the cartridge-removable positio
