Abstract
A sheet conveyor apparatus is provided with a first rotator for supplying the feeding force to a sheet in contact with the sheet, a second rotator for supplying the feeding force to the sheet in contact with the sheet and from the opposite side of the sheet, a drive rotator rotatable by the drive force from a drive source, and a drive transmission for transmitting the drive force of the drive rotator to the second rotator so as to rotate the second rotator at a peripheral velocity higher than that of the first rotator. While the sheet is being conveyed, the drive transmission allows a slip as it transmits the drive force so that the second rotator can rotate at a peripheral velocity in conformance with that of the sheet.
