Abstract

PURPOSE: To provide a sheet feeding device wherein an auxiliary roller rotating at a peripheral speed quicker than the peripheral speed of a conveying roller is provided between a sheet feed roller and a carrier roller, and a detour with respect to the sheet passage is provided, thereby reducing the load applied to the carrier roller due to the tension of the sheet.
CONSTITUTION: A fan 10 is rotated to bring the interior of a casing 11 to be negative in pressure, and a uppermost one of laminated sheets 2 is attracted to the lower surface of the casing 11 to rotate a sheet feed roller 4 and supply the sheets 2 toward a scanner roller 3. The sheets 2 which have passed through a sheet separator 14 consisting of a sheet separating roller 12 and a friction plate 13 is guided by a guide roller 15 and makes a detour around the auxiliary roller 5 and is carried to a treating part 1. When the sheets 2 are tensed, the sheets 2 come into contact with the auxiliary roller 5 rotating at a peripheral speed quicker than that of the carrier roller 3, whereby the sheets are forcibly carried, and the tension thereof is relaxed and the load of the carrier roller 3 is reduced.
