• a. means for pivotably mounting said platen cover containing said transport means to said frame in swing-up relationship from a lowered single sheet operating position to a raised position for providing access to said exposure platen;
• b. means for pivotably mounting said feeder means in a swing-away relationship from single sheet operating position of cooperation with said transport means when said cover is in lowered position, to a removed position to provide side access to said platen;
• and
• c. means cooperating with said drive input to said transport means and with said drive input to said feeder means for actuating said transport and said feeder means when said transport means and said feeder means are in a sheet copying position.
