Abstract
An improved automatic paper feeding device for a facsimile equipment or the like apparatus is disclosed which includes a feeding roller (3) disposed below the feeding end part of an inclined paper feeding board (2) and a reversing roller (7) located above the feeding roller (2) in a line contact relation to be rotated in the opposite direction to that of drawing of papers from the paper feeding board (2), the reversing roller being rotatably supported at the free end part of side plate members (20) adapted to turn about a support shaft (21). A connecting line between the shafts (4,8) of the feeding roller (7) and the reversing roller (7) extends substantially at a right angle relative to a connecting line between the shaft (8) of the reversing roller (7) and the support shaft (21) for the side plate members (20). The direction of tension given by an endless belt (36) for rotating the reversing roller (7) is selectively determined to extend substantially at a right angle relative to the connecting line between the shafts (4,8) of the feeding roller (3) and the reversing roller (7) whereby contact pressure to be exerted on the feeding roller (3) by the tension of the endless belt (36) via the reversing roller (7) becomes practically zero. Thus it is assured that the device is operated without any extra contact pressure active on the feeding roller while fluctuation in contact force is minimized.
