Abstract (en)
[origin: US4561792A] The invention relates to a paper transportation device for printers, which use reel paper, having a motor-driven platen and one paper pressure roller which contacts the platen approximately at the center thereof so that it can be swung away in an elastic manner. The paper pressure roller is motor-driven such that the peripheral speed of the paper pressure roller leads the peripheral speed of the platen and by virtue of the arrangement of the paper pressure roller, the maximum possible angle of loop ( beta ) of the paper and the platen is achieved. This angle is delimited by the paper pressure roller and by a paper guidance channel which is aligned to lead tangentially away from the platen. The paper guidance channel is preceded by a device which produces a bias between the paper and the platen.
