摘要
A rolled paper supporting means 12 rotatably supporting a rolled paper is connected to a rotary drive system and arranged under a platen 2. In a paper sheet conveying route between the rolled paper supporting means 12 and the platen 2, pairs of tension rollers 20 and 24 are arranged leaving gaps a little larger than a thickness of the paper sheet. When a paper sheet passes through the gaps between these tension rollers 20 and 24, a weak braking force is given to the paper sheet in order to prevent the paper sheet from snaking. A sheet holding plate 29 is swingably arranged on the tension roller 24 of the pairs of tension rollers 20 and 24 so as to come in contact with and detached from the tension roller 24. The sheet holding plate 29 is pressed onto the tension roller 24 through a paper sheet on the tension roller 24 with a predetermined pressing force, preventing the paper sheet from being pulled in a reverse direction of the paper sheet conveying and feeding direction through the gaps of the pairs of tension rollers 20 and 24.
