Copier and multifunction paper cassette

A cassette for use with a copier or the like having sheet feeding means, said cassette providing sheet supply storage for a stack of sheets to be used in the copy process, and also providing a bypass sheet entry station for use in allowing a bypass sheet to be substituted for a sheet of the stack, comprising:

• a frame having upper and lower spaced walls forming a chamber for storing a stack of supply sheets, and including an opening at one end of said upper wall for permitting extraction of the top sheet of a stack;
• and
• means forming a tray on said upper wall external to said chamber and including movable gate means adjacent said opening, said gate means being movable between a first closed position and a second open position, said gate in said open position allowing a bypass sheet to be moved from said tray into overlying relation to said opening and the underlying stack.

A combined copy sheet supply and output tray cassette for use with a copier which includes a copy sheet input mechanism adjacent an input slot and exits completed copies at an output slot, comprising:

• a sheet supply section having an opening for cooperating with the copier input mechanism, an output tray overlying said sheet supply section, a gate mechanism in a wall of said tray, and means for selectably actuating said gate mechanism for allowing a bypass sheet to be interposed into the copier input mechanism to the exclusion of sheets in said supply section whenever said gate mechanism is actuated.
