<p>PURPOSE:To prevent load from being changed by slip between paper and a relay roller according to the transfer path of a resist roller for stabilization of roller transfer by redriving the relay roller with equal speed in synchroniza tion with the drive of the resist roller. CONSTITUTION:While a resist roller 18 sends paper, a relay roller 16 is rotated by a separate drive with the same speed as the resist roller 18 for a certain time in every paper size to hold the paper flexion formed in a buffer 13. And in a paper feed section 4, a paper feeding roller 8 and relay rollers 17, 16 are sequentially driven and temporarily stopped after forming the flexion of paper in the buffer 13. Here, while same applies to the paper feed section 4, the drive of paper feeding rollers 7, 8 is stopped when the end of paper reaches the relay rollers 16, 17 at the nearest downstream side. Next while the resist roller 18 sends paper, the relay rollers 16, 17 are rotated with the same speed as the roller 18 according to the paper size to form a proper flexion in a portion of the buffer 13. Thus, load for driving the resist roller at every paper feed section is uniformed.</p> |
