ABSTRACT:
A double feed detection method for detecting whether sheet materials are double fed or not, which has an external force application member for applying an external force to a sheet material by bringing external force applicator into contact with the sheet material and a detector for detecting the external force applied to the sheet material by bringing itself into contact with the sheet material and determining whether the sheet materials are double fed or not using a signal obtained from the detector.
