ABSTRACT:
Disclosed is a transfer type each-side exposure apparatus which comprises light sources which oppose each other and transfer means which transfer materials to be exposed between the light sources. In one aspect, the apparatus further comprises light shielding means which prevent the passage of the light rays for irradiation as required, and control means which controls the actuation of the light shielding means. In another aspect, the apparatus further comprises reflectors which consist each of a cold mirror. In still another aspect, the apparatus is such that the light sources are each disposed in a manner that a cathode constituting its light emitting portion is displaced by a small distance from one of focal points of a corresponding reflector provided in the light source.
