Then, whether the sheet size is larger than B-4 is checked, and the number of sheets is checked. And, when the size is larger than B-4 or when the number of sheets is larger than a defined number, the speed of a conveying motor is reduced by means of a control device, a stopper 519 is released, and the bundle of sheets is conveyed to a stack tray 513 by a belt 531.
