PURPOSE:To prevent oblique advance of paper, in paper carrying system for inverting the direction of paper along the outercircumference of drive roller, by providing a drive belt for guiding the paper along the outercircumference of drive roller. CONSTITUTION:Idlers 2, 6 are faced against a drive roller 1 while paper guides 3, 5 are arranged between the drive roller 1 and a drive roller 4 for inverting the direction. Here, a drive belt 10 is arranged while contacting tightly against the outercircumference of the drive roller 4. The drive belt 10 is applied over the belt wheels 11-13 and rotated in same direction with the drive roller 4 through rotation of the belt wheel 11. Consequently, the paper (P) fed to the side of drive roller 4 is bitten by the drive roller 4 and drive belt 10 to invert the direction. Since the paper will contact tightly against the outercircumference of drive roller 4 and never separate, it will never advance obliquely. |
