Abstract
An expandable cassette for use with device to support a sheet that is fed into from a communication machinery. The expandable tray may include a first tray and a second tray mounted on the first sheet support so that the second tray can be rotated around a shaft that is attached to tray in the direction that paper is discharged from the image forming device. A third tray may be slidably mounted on the second tray in such a manner that the third tray is moveable back and forth along direction that paper is discharged from the image forming apparatus.

A cassette for an electrophotographic apparatus, comprising:
- a first tray engageable with said electrophotographic apparatus and having a first major surface, said first tray comprising:
- a shaft protruding from said first major surface;
- and
- a plug protruding from said first major surface;
- a second tray rotatably attached to said shaft of said first tray and having a second major surface, said second tray comprising:
- a elongated slot for receivable engaging said plug of said first tray while accommodating rotation of said second tray relative to said first tray from a first position with said second major surface overlying said first major surface to a second position with said second major surface cantilevered beyond said first major surface;
- and
- a pair of guide rails disposed on said second major surface:
- a third tray providing a third major surface slidably engaged with said pair of guide rails of said second tray to slidably position said third tray at varying distances from said electrophotographic apparatus;
- and
- said first tray, said second tray, and said third tray being mutually adjustable to support a stack of a plurality of cut sheets of a printable medium of any one of various sizes.

A cassette for an electrophotographic apparatus, comprising:
- a first tray engageable with said electrophotographic apparatus and having a top side, said first tray comprising:
- a shaft protruding from said top side;
- and
- a plug protruding from said top side;
- a second tray rotatably attached to said shaft of said first tray and having a top surface, said second tray comprising:
- a slot for receivably engaging said plug of said first tray, said slot being curved to allow the rotation of said second tray, through an angle of about 90 degrees, from a first position over said first tray to a second position with said second tray cantilevered over said first tray
- a bump proximate to each end of said slot disposed on an edge of said slot to engage said plug of said first tray to stabilize said second tray in either one of a fully extended position and a fully retracted position;
- and
- a pair of guide rails disposed on said top surface,
- a third tray slidably engaged with said pair of guide rails of said second tray:
- and
- said first tray, said second tray, and said third tray being adjustable to accommodate a stack of a plurality of cut sheets of a printable medium of any one of various sizes.
