Patent ID: 7249941

Claim:
A device for manufacturing a plastic lens by irradiating active energy rays onto a casting mold injected with plastic composition to polymerize the plastic composition, the device comprising: a rotary table for transferring a plurality of casting molds in a circular manner: a driving means for rotatively driving a rotation axis of the rotary table: an irradiating portion irradiating the active energy rays in a predetermined angular range onto at least one casting mold when the casting mold loaded on the rotary table is rotated once; a control means for controlling the driving means to irradiate the active energy rays from the irradiating portion onto the at least one casting mold for a predetermined period of time; a supplying/removing portion for supplying and removing the at least one casting mold to and from the rotary table; a first temperature adjusting portion for controlling the temperature of the irradiating portion; a cooling portion for gradually cooling the at least one irradiated casting mold; a second temperature adjusting portion for controlling temperature of the cooling portion; and separating means for separating atmospheres formed in the supplying/removing portion, the irradiating portion, and the cooling portion when the rotation of the rotary table is stopped, wherein the supplying/removing portion, the irradiating portion, and the cooling portion are sequentially arranged in a circular fashion, in a direction of rotation of the rotation axis of the rotary table in a vicinity of the rotation axis.
