Abstract

PROBLEM TO BE SOLVED: To provide a paper sheet carrying device in a bookbinding system in which the time for bookbinding can sufficiently be insured in bookbinding processing on the paper sheet, which is sent at a certain interval, for a plurality of booklets. SOLUTION: In a paper sheet carrying device, the paper sheet for a plurality of booklets is sent in order of the page of respective booklets and carried to the bookbinding position order of the receipt. In this case, a one-way clutch 12, which is driven by a motor 11 at a low speed, and an electromagnetic clutch 16, which is driven at a high speed, are installed in both ends of a revolution transmitting shaft 17 for driving a carrying belt 19, which receives the paper sheet that is sent in and which carries out the paper sheet up to the bookbinding position. The ordinary revolution, transmitting shaft 17 is connected to the electromagnetic clutch 16 so as to drive the carrying belt 19 at a high speed. After the last (back) page of the booklet is sent out, the clutch is switched to the one-way clutch 12 so as to drive the carrying belt 19 at a low speed, so that the carrying-out of the first page of the subsequent booklet is delayed, thereby insuring sufficient bookbinding time.
