PURPOSE:To avoid the loosening of recording papers when being pulled out by using a tortional coil spring for the coil spring of a rolled paper supporter. CONSTITUTION:One end of a torsional coil spring 24 is fixed to a right-handed presser 21 and the other end is fixed to a rotary plate 25. When a recording paper 2a is pulled out of a rolled paper 2, the notch 2c of a winding core 2b is coupled with the projection 23a of a right-handed reel 23, and the paper 2 and the plate 25 are turned at the same angle. The rotation of the reel 23 is transmitted even to the plate 25 through a slip plate 26, and however, the action of the plate 25 is limited by the spring 24. For this reason, when a fixed angle is reached, the recovery force of the spring 24 becomes greater than the friction with the plate 26, and while slip occurs between the plates 25 and 26 the paper 2a is drawn out. The loosening of the paper 2a is absorbed by the spring 24. Also, the rotation of the left-handed reel 31 is regulated by a coil spring 32. |
