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