Abstract
A duplex copying machine having a simple and automatic method and apparatus for handling paper at a duplex feeding station in a duplex copier is disclosed. A container for holding a stack of paper is removably connected to the duplex copier at a paper feeding station. The stack of paper is aligned and partially confined within the container by vertically extending surfaces which align the edges of the paper sheets within the stack. Top portions connected to the vertical surfaces extend horizontally over a portion of the top sheet of the stack. The stack of paper rests on an intermediate support plate within a container which is biased against the top portions. Extension members connected to opposite sides of the intermediate support plate are disposed to move within slots in opposite sides of the container. A pair of solenoids are connected to contact members and fixed to the duplex copier. When the container is mounted on the duplex copier the contact members come in close proximity to the extension members. When it is desired to automatically deposit sheets of paper having copying on one side into the container for duplex copying, a duplex signal is transmitted to the solenoids w…
