ABSTRACT:
A printing paper winding device for enabling winding of printing paper even paper with a base material having a low resistance to bending stresses or printing paper having RFID labels carrying IC chips. Bending stresses are reduced by dividing the movement region of the tension roller into four regions in order to enable the successive detection of the position or posture of the tension roller and by making the bending angle of the printing paper in the winding path close to a more obtuse angle. A winding control unit of the present invention determines whether the tension region where the tension roller is positioned is a first tension region, second tension region, third tension region, or fourth tension region, controls the drive unit to limit the tension roller to a tension region in which winding is possible in the direction such that the bending angle of the printing paper in the winding path, which follows the winding of the printing paper, is close to a more obtuse angle.
