Abstract
We examined the behaviors of the paper sheet in the overlap-type isolation mechanism of the paper sheets. First, we introduced the formulation that can calculate the resistance force and feed force acting on the paper sheets in the mechanism. And, based on the calculation results of the resistance force and friction force between the paper sheets, we examined the behavior of the paper sheet. As a result, we found that the separation mechanism that can separate the paper sheets piled up to one piece exists in the overlap-type isolation mechanism, and that the separation mechanism is a superior factor than the other isolation mechanisms.
