1. A method of producing a lens molded article with a mold including an upper mold and a lower mold, the method comprising:
a state determination of determining, after molding the lens molded article, whether a state is a first state where the lens molded article molded remains in the upper mold with the upper mold and the lower mold separated from each other or a second state where the lens molded article molded remains in the lower mold with the upper mold and the lower mold separated from each other;
an adsorption of adsorbing, in accordance with a determination result in the state determination, an exposed surface of the lens molded article remaining in the upper mold or the lower mold, by an adsorption device disposed at a tip of an arm of a molded article moving device;
an adsorption surface change of changing an adsorption surface from a surface adsorbed by the adsorption device to an opposite surface to the exposed surface when the determination result in the state determination is either one of the first state or the second state; and
a placement of placing the lens molded article on a tray by releasing adsorption by the adsorption device of the lens molded article adsorbed by the adsorption device.
