<p>PURPOSE:To maintain the high productivity and suppress noise in the paper transfer. CONSTITUTION:A paper sheet 21 is once stopped in the vicinity 6 of a resisting roller 22 as paper matching part 20, by a paper top edge detection signal detected by a resistance sensor 23. Then, a relaying roller 30 is driven earlier by the time for forming a loop from the operation timing of the paper matching part 20 which is determined from the relation with an image forming part 10, and the top edge of the paper is collided with the paper matching part 20, and the loop is formed. Since the paper sheet collides with the paper matching part 20 in the accelerating process of the relaying roller 30, i.e., at the slow transfer speed, the collision noise with the paper matching part 20 and the noise in the attachment of the formed loop onto a chute 24 are reduced.</p> |
