PURPOSE:To facilitate setting a recording paper and prevent a line pitch in line feeding from fluctuating, by a construction wherein a vertically movable paper guide is pressed upward by a spring with a spring constant rapidly varied. CONSTITUTION:A rolled form recording paper 1 is placed in a casing 2, an end of the paper 1 is inserted between a rubber roller 3 and the paper guide 9, and when the roller 3 is rotated, the end of the paper 1 is pulled while being wound around the roller 3, and the guide 9 is depressed downward against the force of a helical spring 10. In this condition, recording is conducted. In line feeding, the roller 3 is rotated, and the paper 1 is pulled. When a roll part 1a of the paper 1 is large, the guide 9 is depressed further downward, and a length of the paper 1 corresponding to the displacement of the guide 9 is fed. An arm part of the spring 10 making contact with a boss 2c produces a larger force for pressing the guide 9 upward, and after line feeding, the guide 9 rotates the roll part 1a, resulting in an initial condition. |
