A sheet feeding apparatus comprises a sheet conveying mechanism for conveying sheets along a first conveying path ( ) and stacking up them in a sheet stack-feed station (S), a tray ( ) for storing a stack of cover sheets (P), a second conveying path ( ) communicating with the first conveying path ( ), a blow outlet ( ) for blowing a jet of air towards the tray ( ) to lift up each cover sheet (P), a sucker ( ) for sucking the cover sheet (P), a sheet feeding mechanism for conveying the cover sheet (P) received from the sucker ( ) along the second conveying path ( ) and feeding it to the first conveying path ( ), and a pneumatic pump ( ) for providing a blow of air and a suction of air. 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.
