Abstract
It is important in design to prevent the device from trouble during carrying paper, in paper handling system such as ATM, which carries paper sheet at high speed. In this study, the behaviors of the paper, normal carrying, carrying through and jam, are analyzed for various design conditions of the device and some kind of the paper configurations by experiment and FEM, and the relations between paper behavior patterns and their conditions are investigated. As a result, prediction expressions for each trouble pattern are devised from frictional law and the causes of their patterns are discussed.
