ABSTRACT:
The present invention is a sheet feeder for use in combination with a printer. The sheet feeder includes a frame which is substantially symmetrical about a bisecting vertical plane and which has a sheet outlet. The top of the frame is in a first horizontal plane and the printer, which has a sheet inlet, is disposed thereon. The sheet outlet is adjacent and contiguous to the top of the frame and can be aligned with the sheet inlet of the printer. The sheet feeder also includes a first tray and a second tray which are movably coupled to the frame and which are disposed opposingly to each other and parallel to a first plane and a second plane, respectively, which are slanted with respect to the first horizontal plane. A first stack of sheets, face up, and a second stack of sheets, face down, can be disposed on the first and second trays, respectively. The sheet feeder further includes first and second feed rollers, first and second supporting mechanisms for supporting the first and second trays, respectively, and first and second resiliently biasing mechanisms for resiliently biasing the first and second trays, respectively, whereby the first and second trays urge the first and second stacks of sheets, respectively against the first and second feed rollers, respectively.
