ABSTRACT:
A cassette for feeding envelopes to a printer. The cassette includes an elevator mechanism for continuously raising a stack of envelopes to maintain contact with a feed mechanism in the printer as envelopes are fed from the stack. The elevator pivots vertically around its back edge and is hinged to rotate orthogonally to the direction in which the envelopes are fed. The orthogonal rotation allows the envelope to remain horizontal even through the stack of flaps is thicker along its flap edge.
