Abstract

PURPOSE:To send paper sheets, always keeping a constant interval, even if each paper sheet has different thickness, by installing a driving roller for stopping or starting the revolution movement by the output signal supplied from a detector. CONSTITUTION:When a paper sheet 12e is transported by a pick-up roller 15, one among the detectors 10a-10e is turned-OFF from ON, and a driving roller 11 is restarted by the signal, and feeding of the next paper sheet 12c is started. Then, the interval between two paper sheets 12e and 12c transported continuously from the time when the transport of the paper sheet 12e proceeds and the terminal edge passess through a detector 10a to the time when the top edge of the paper sheet 12c reaches the position of the detector 10a is measured. This measured interval is compared with a previously set value, and the acceleration time or deceleration time necessary for correcting the interval is calculated, and the operation of the pick-up roller 15 is controlled. Through this operation, the interval between the papers continuously sent out one by one from an adsorbing belt 2 can be always kept constant.
