Abstract

A sheet-holding cassette for a copying machine is formed as a box containing a stack of copy sheets. This box is adapted to be held in the machine with the uppermost sheet of the stack engageable with the paper-advance roller of the machine. A slot is provided in the upper wall of this cassette as well as a guide next to this slot and a deflector in back of this slot so that an extra sheet can be slid along the upper wall of the machine and into the cassette to lie at least at its front edge on top of the stack of sheets in the cassette. Thus as the paper-advance roller is reciprocated down onto the stack it will pick up this extra sheet rather than the top sheet of the stack, allowing a copy to be made on a single extra copy sheet without having to reload the machine.
