Paper sheet multi-feed preventing member

Abstract

A paper sheet multi-feed preventing member 3 being planar includes an outer layer 8 which comes into contact with a paper sheet 5 and an inner layer 9 laminated on the outer layer 8, the inner layer 9 has a type A durometer hardness not less than A5/S and not more than A60/S, or an Asker-C hardness not less than C5 and not more than C50, and the outer layer 8 has a rubber hardness higher than that of the inner layer 9.
