<p>PURPOSE:To prevent slipping between a feed roller and a paper sheet by non- linearly controlling the rotating speed of the feed roller in such a manner as to gradually increase. CONSTITUTION:When a paper feed start signal is input to a control device, the rotation of a rotation driving source 4 is controlled non-linearly in such a manner that the rotation of the rotation driving source 4 is accelerated gradually from the paper feed start point t1 and reaches a designated peripheral speed v1 after the lapse of several hundreds of miliseconds to several seconds. Accordingly, a feed roller 2 to which rotation is transmitted through a chain 6 is also rotated, so that the feeds roller 2 pressed to a paper sheet 1 starts feeding out the paper sheet can be fed out without slipping between the feed roller 2 and the paper sheet 1.</p> |
