XEROGRAPHIC FUSING APPARATUS

摘要

XEROGRAPHIC FUSING APPARATUS of the Invention A fusing apparatus for an electrophotographic copying machine in which heat fusible developing material is deposited in image-wise configuration on a sheet of paper and fixed thereto by the application of heat. The fusing apparatus has a conveyor system for conveying the sheet of paper past a source of heat for fusing the developing material into the paper. The fusing apparatus includes a secondary driving means to maintain operation of the conveying system in the event of any failure of the normal source of driving power to the conveying system so that the conveying system does not stop with the sheet of paper still adjacent the source of heat, which would allow the sheet of paper to catch fire. The secondary driving means includes stored energy means which becomes automatically operable to maintain operation of the conveying system for a period of time sufficient to eject the copy sheet from the fusing apparatus in the event of an electrical power failure in the copying machine.
