Filed: 1987-12-07
Abstract: PURPOSE:To stably feed documents different in size and paper quality by providing means capable of reliably separating documents sheet by sheet from the uppermost sheet first on a paper feed mechanism for feeding out documents sheet by sheet, which are loaded in an optical character recognition device or the like. CONSTITUTION:When a roller 2 is rotated, rollers 1, 6 are rotated by belts 14, 15, and as the peripheral speed of the roller 6 is larger than that of the roller 1, there is a difference in speed for feeding out the first document 18 to form a rising portion in the document 18. The document 18 is passed between rollers 2, 3 and nipped between the rollers 5, 6 to be fed out in the transport direction 16. When the document 18 is nipped between the rollers 5, 6, the driving force to a shaft portion 9 is removed to stop rotation, so that shaft portions of the rollers 1, 6 are stopped. The rollers 1, 2, 6 are, however, rotated by turning force given by frictional force between the rollers and the document 18 by action of clutches 19, 20, 21, so that the peripheral speeds of the rollers 1, 2, 6 become equal to the speed of the document 18 to complete feeding out one sheet document 18.
