PROBLEM TO BE SOLVED: To provide a feeder capable of automatically lining up a sheet block formed by simultaneously falling a plurality of sheets to a lap shape when the sheet is made to the lap shape. SOLUTION: A double-row of lining up conveyors 40 are arranged on a sheet conveying passage of a sheet conveying device 30 for making the falling corrugated board sheets S<SB>0</SB>fed from a sheet inversion base 12 to the lap shape and feeding to a sheet feed part 2 of a sheet processing machine 1 and are pivotably supported making an upstream side end as a center. At conveying of the falling corrugated board sheets S<SB>0</SB>fed onto the sheet conveying device 30, the falling corrugated board sheets S<SB>0</SB>are fallen directed to a front side in a conveying direction to make them to the lap shape. When the sheet block B is conveyed onto the lining up conveyor 40, the lining up conveyor 40 is repeatedly fallen. At standing up of the lining up conveyor 40, a plurality of corrugated board sheets S<SB>1</SB>forming the sheet block B generate slip at mutual contact parts to line up them to the lap shape.
