Claim Text:
1. An apparatus for producing a laminated body including a film substrate and at least one vapor-deposited polymer film deposited on the film substrate by a vacuum deposition polymerization, the apparatus comprising: a vacuum chamber; an exhaust means that exhausts an air from the vacuum chamber to make the vacuum chamber in a vacuum state; a rotary drum that is rotatably provided in the vacuum chamber, the rotary drum having an outer peripheral surface on which the film substrate is provided so as to be in contact therewith, whereby the film substrate is allowed to be traveled in the circumferential direction along with the rotation of the rotary drum; a film substrate supply means that supplies the film substrate on the outer peripheral surface of the rotary drum; a plurality of blowoff members positioned around the rotary drum so as to be in line with each other in the circumferential direction, each of the plurality of blowoff members including a vapor outlet that opens inside the vacuum chamber to the outer peripheral surface of the rotary drum and an inner space that is defined by a cover wall; a plurality of deposition chambers each constituted by a part of the inner space of each of the plurality of blowoff members and positioned inside the vacuum chamber; and at least one monomer vapor supply means including: a plurality of evaporation sources that each generates a kind of monomer vapor, so that a plurality of kinds of monomer vapor are generated, by heating and evaporating respective kinds of material monomer; and a plurality of communication passages that communicate the plurality of evaporation sources with a corresponding one of the plurality of deposition chambers, whereby the plural kinds of monomer vapor are blown off from the vapor outlet of each of the plurality of blowoff members; wherein a distance between the vapor outlet of each of the plurality of blowoff members and the outer peripheral surface of the rotary drum is 5 mm or less, and an intervening wall is provided to divide the inner space of each of the plurality of blowoff members into a mixing chamber into which the plurality of kinds of monomer vapor are introduced so as to be mixed together therein and the deposition chamber including the vapor outlet, and a communication hole is provided through the intervening wall such that the mixing chamber and the deposition chamber communicate with each other through the communication hole, whereby the plurality of kinds of monomer vapor introduced into the mixing chamber and mixed therein are supplied to the deposition chamber through the communication hole of the intervening wall.
