  • Patent number: 4056321
    Abstract: The duplicator comprises a housing with a carrier supporting first and second spaced platens alternately movable by the carrier to a light exposure station in the housing. Master microfiches to be duplicated are manually positioned on the platens such that when a master microfiche on the first platen is in the housing being exposed, a second master microfiche may be loaded on the second platen, preparatory to having a duplicate made. A foot pedal is provided to actuate movement of the platen carrier and also control a vacuum hold down system for the master microfiches positioned on the platens. A capstan driven by a geneva movement in the housing positions successive lengths of film from a film reel in the housing at the light exposure station for contact printing with the master microfiche on the platen positioned at the light exposure station.
