PURPOSE:To enable the normal supply and discharge of continuous paper by preventing the detachment of the continuous paper, by making the radius of curvature of the driving rotor or guide member arranged to the side of a platen larger than that of the guide member or driving rotor provided in the post stage thereof. CONSTITUTION:The radius of curvature r1 of the driving rotor 9C in the side of a platen 4 is larger than the radius of curvature r2 of a guide membaer 9D and continuous paper 7 is prevented from contacting and engaging with guide plates 10A, 10B between a tractor and the platen 4. The driving rotor 9C slide with a drive shaft 5B allows an endless belt 8 having the projections 8A engaging with the feed perforations 7A of the continuous paper 7 to rotate to a predetermined direction. By this rotation, the continuous paper 7 in the side of the guide plate 10A is discharged while the continuous paper 7 in the side of the guide plate 10B is supplied. Because the continuous paper 7 is supplied and discharged almost straightly in supply and discharge routes, the continuous paper 7 can be prevented from being detached from the tractor 6. |
