  • Patent number: 4017184
    Abstract: Apparatus for automatically copying information contained on sheets of translucent material such as microfilm cards when such master sheet is loaded into the apparatus and dials on the control panel are set to the desired number of copies. The device includes subsystems for unwinding, exposing, cutting and developing a web of sensitized copy material on a continuous flow basis. A control system causes the device to wrap the translucent master sheet around a transparent printing cylinder during exposure and to cut the web of copy material in the proper relationship to the exposed images. The transparent printing cylinder has an outside circumference which is approximately equal to the distance between the locations at which the web of copy material is cut.
