The sheet feeding mechanism is changed to its standby mode when the cover sheet is transferred from the sucker ( ) to the sheet feeding mechanism. Upon the sheets having been stacked in the sheet stack-feed station (S), the sheet feeding mechanism transfers the cover sheet. During the standby mode, the pneumatic pump ( ) remains inactivated.
