  • Patent number: 9022553
    Abstract: A printer has a paper feed roller and a pressure roller on the upstream side of a platen in the paper feed direction. These rollers nip the continuous paper at a nipping position. When the pressure roller bends down due to pressure from the paper feed roller, the pressure roller moves on a curved path centered on a pivot point of a paper pressing lever. The nipping position of the continuous paper therefore follows the downward movement of the paper feed roller and moves to the side away from the platen along the outside surface of the paper feed roller. The slope ? of the tangent to the nipping position therefore changes, the leading end of the continuous paper conveyed to the platen side rises, and slack in the continuous paper is removed.
