Abstract
A multiple feed detecting system is provided with a sheet thickness sensor which outputs thickness signals representing the thickness of a sheet to be conveyed, and a sheet size sensor which detects the size of the sheet to be conveyed as measured in the direction of conveyance. A detecting area is set according to the size of the sheet detected and whether multiple feed occurs is determined on the basis of sampling data obtained by the sheet thickness detecting sensor over the detecting area set.
