Abstract

Disclosed is a sheet separation method for separating a sheet one by one from a bundle of the sheets (11) and feeding the separated sheet to a next processing step, including: suctioning an edge part of the sheet and pulling the suctioned edge part from the bundle as if to turn over the suctioned edge part (34); separating the sheet from the bundle, the edge part of the sheet being suctioned and pulled (36a); and conveying the sheet separated from the bundle in a predetermined direction (D2). A sheet separation mechanism and a sheet feeder are also disclosed.
