  • Patent number: 5397120
    Abstract: An apparatus for stacking successive rapidly advancing sheets of a stream of sheets has a platform which receives successive sheets and descends at the rate of accumulation of one or more stacks thereon. The sheets are delivered by one or more overhead belt conveyors in cooperation with one or more lower belt conveyors. The front end turn of the lower reach of each overhead conveyor is deflected around a small-diameter rigid rod immediately in front of a stop for the leaders of successive sheets to reduce the likelihood of buckling during stacking, and one or more downwardly sloping ramps are provided in front of the stop to deflect the leaders of successive sheets in a downward direction toward the leaders of the immediately preceding sheets in immediate or close proximity of the stop. The stop, the rod and the overhead conveyor or conveyors are adjustable in several directions to facilitate a change of setup for the stacking of longer, shorter, wider or narrower sheets.

  • Patent number: 5220396
    Abstract: In an electrophotographic printer using a continuous-form sheet as a recording medium, there is provided a sheet separating mechanism comprising an elastic member arranged to be deformed by the continuous-form sheet, that is pressed by a transferring charger, when the transferring charger is located at an operating position and a transferring operation is to be executed, or to be released from the deformation when the transferring charger is retracted from the operating position. Thus, the continuous-form sheet is definitely separated from a photoconductive material by the elastic member as it is released from the deformation, when the transferring operation is not to be executed.
