Patent ID: 6877973

Claim:
An apparatus for manufacturing a lens sheet comprising; an application device for applying ionizing radiation curing type resin in a form of liquid on an upper surface of a forming die for a lens sheet to form an uncured resin body on the upper surface of said forming die; a substrate supply device for placing a substrate on said uncured resin body; a pressing device for pressing said substrate against said uncured resin body to flatten said uncured resin body, so as to form a uncured resin layer, while spreading said uncured resin body to an outside periphery of said forming die; an irradiation device for irradiating ionizing radiation on said uncured resin layer through said substrate to cure said uncured resin layer; and a circulation device for circulating the ionizing radiation curing type resin, when the application of the ionizing radiation curing type resin by said application device is temporarily stopped, while adjusting the temperature thereof.
