PURPOSE:To feed a paper smoothly, by providing a plastic slide disc between one inverted roller and an intermediate roller to keep always the state of an initial contact between the inverted roller and the intermediate roller. CONSTITUTION:An inverted roller 5 is fitted rotatably freely to one side of a shaft 10 through a bearing 16, and the end face is fixed by an E ring in 13, and an intermediate roller 1 is fitted to the other side through a slide disc 14, and the bearing is pressed to the intermediate roller 1 from the outside through a bearing stopper 15 by a spring 17. In this case, slide disc 14 is inserted through the shaft 10 so that an end face B of a small ring 14e of the slide disc 14 is brought into contact with the end face side of the inverted roller 5, and further, the intermediate roller 1 is fitted and is pressed to the slide disc 14 through the bearing stopper 15 from one side by the spring 17. Since the slide disc 14 has rings 14a, 14c, and 14e and legs 14b and 14d, the contact face is made uniform. |
