<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic paper feeder which suppresses the manufacturing cost by forming an air flow of a plurality of combinations from an air flow supplied from one blower. <P>SOLUTION: The pneumatic paper feeder comprises a cylinder having a first air vent communicating with a supply source of air flow, and second, third, fourth and fifth air vents communicating with an injection port of the air flow, and a main rotor and a sub rotor rotating in the cylinder. The main rotor has a notch for selectively communicating the first air vent and the second or third air vent according to the turning position. The sub rotor forms the plurality of air flows from one blower using an air flow distributing device having a notch for selectively communicating the first air vent and the fourth or fifth air vent according to the turning position. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
