Abstract
An automatic microfiche duplicator having an upper receiving slot for receiving a copy sheet and master sheet, and a first conveyor which transports the copy sheet and master sheet together in a generally horizontal direction past an exposure cylinder where the copy is exposed and then to a separator which automatically separates the master sheet down and away from the copy sheet. Three embodiments of the separator are illustrated (FIGS. 9-11, 12-14, and 15a-c). The master sheet is then delivered to a reverse, lower conveyor which conveys the master sheet in a reverse horizontal path to an exit tray located below and near the receiving slot. A second upper conveyor transports the exposed copy sheet in the same general horizontal direction as before to a belt driven cylindrical heat developer and then down to a cooling tray where the copy is held for a few seconds. An automatic mechanism tilts the tray which is slotted and delivers the cooled copy to the lower conveyor (made of a set of ring belts) which then delivers the copy back the same reverse path followed by the master to the exit tray.
