  • Patent number: 4265441
    Abstract: A sheet dispensing device having a pair of lateral guides defining a space within a housing for insertion of a container containing a stack of sheets. The dispensing device comprises a conveyor, which is reciprocated within the housing to carry the uppermost sheet from the container and dispense the same from the device, and a separator designed to retain all sheets with the exception of the uppermost sheet in the container. The dispensing of a sheet operates a switch to then energize the copying machine. The container has a pair of laterally extending flange-like members to engage laterally spaced guides in the housing and is perforated along two sides on the upper surface to permit removal of a section of the container to expose the uppermost sheets.
