Abstract
In order to clarify why the isolation performance of the overlap-type isolation mechanism of the paper sheet is superior to the pressure-type isolation mechanism,we examined the behaviors of the paper sheet in the both mechanisms.First,we introduced the formulation that can calculate the drug force and the feed force acting on the paper sheet in the overlap-type mechanism.And,based on the calculation results of the drug force and friction force between the paper sheets,we examined the behavior of the paper sheet.As a result,we found that a separation mechanism which can separate the paper sheet piled up to one piece exists in the over lap type mechanism,and that the mechanism is a superior factor than the pressure type.
