Abstract: A scanner system and method are described, wherein two lenses are mounted on a slider positioned in the optical light path between two moving mirrors and the optical sensor. Each mirror is mounted on a moving carriage. The slider is bistable in two alignment positions, one for each lens. The slider is moved by the motion of one of the carriages. As the carriage moves toward the lens slider, a linkage causes the slider to move from the position it is currently in to the other position. This system allows the slider to be shuttled from one position to the other, thereby changing resolutions, using energy provided by the same motor that moves the mirrors.

Abstract: A beltless, automatic document feeder for a flat bed document scanner or other hard copy apparatus using a flat bed scanning station is disclosed. A paper path is formed between a feeder frame guide and a paper loading tray. A document sheet pulled from a stack loaded in the tray is transported along the path by a dual function driver. A pad overlaying the flat bed of the scanner is provided with a cooperative lip such that the leading edge of the pulled document sheet is directed from the paper path to the flat bed and under the pad. A second, bi-directional driver, associated with the pad and the flat bed, transports the document sheet to a fully scannable position between the pad and flat bed without releasing the trailing edge of the document sheet. After scanning, the second driver is reversed to remove the scanned document sheet from the bed and transport it to the dual function driver which then ejects the sheet along a second path. The first path and second path are on the same side of the flat bed.
