Matthews Assistant Examiner-Monroe H. Hayes Attorneys-James J. Ralabate, Melvin A. Klein and Norman E. Schrader ABSTRACT: Sheet feed apparatus for an automatic copy machine in which a plurality of tray members support a corresponding stack of sheets. Baffle members arranged at the delivery end of sheet tray members define a common exit path leading toward copy processing stations and feed means associated with each of the stacks engage the topmost sheet of a corresponding stack in response to electrical signals. A control circuit supplies electrical signals to the appropriate sheet feed means to feed automatically a preselected sheet from a one of said stacks toward a common exit path for transport past copy processing stations in accordance with a selected image size to be produced.
