PURPOSE:To make a curl correctable steadily even if a roll diameter of recording paper varies, by installing a holder being energized upward and holding the roll recording paper movably, while making paper feeding to a curl correcting paper guide constant. CONSTITUTION:Roll recording paper 3 is made so as to be movably held by a holder 15 being energized upward with a spring installed on a spring holding plate 13, and when a roll diameter of the roll recording paper 3 becomes smaller, the holder 15 and the recording paper 3 are pushed upward with this diametral reduction. Therefore, in the roll recording paper 3, a state of paper feeding to a paper guide part 12 is constant all the time even when its roll diameter is large as well as when becoming smaller, so that it always comes into slidingly contact withthe paper guide part 12, thus a curl is corrected. At this time, since an upper part of the roll recording paper 3 touches a tension roller 16, there is no fear of making load larger and paper feeding takes place so smoothly, thus the occurrence of a paper jam or the like is well reduced. |
