<p>PURPOSE:To stabilize a pneumatic paper feeding motion by making by securing a stable air flow (suction force and blowing force), in a device which performs the feed and separation of paper with this air flow. CONSTITUTION:When paper suction or separation is carried out by way of leading suction force or blowing force, to be produced by fans 1, 11 to be driven by motors 2 and 12, to a suction part 6 and a blowoff part 16 by ducts 5 and 15, two measuring instruments 8 and 18 measuring those of suction force and blowing force are set up in these ducts 5 and 15, and on the basis of the measured value, each rotation of these motors 2, 12 is controlled.</p> |
