Abstract
A paper feeder includes a conveyor for conveying a single paper fed from the upstream side to the downstream side along a transport path while sucking the paper. A suction mechanism faces the conveyor for holding another paper fed together with the above paper by suction. A moving device moves the suction mechanism in a direction perpendicular to a direction of paper conveyance. The paper feeder is capable of accurately feeding various kinds of papers without regard to their thickness or size and delivering even a paper fed together with another paper to a transport path without discharging it to the outside.
