This paper describes basic study on the dynamic behavior of a sheet of paper that moves near a guide plate in a feeding path in the air. Because pneumatic pressure around paper significantly affects dynamic behavior of the paper placed near the guide plate, a numerical program that solves unsteady flow of noncompressible fluid governed by Navier-Stokes equation with the Finite Element Method and calculates the pressure and velocity of the surrounding air of moving paper was firstly developed. In order to verify the validity of the developed calculation program, a simple case where a horizontal plate vibrates near a horizontal guide in the vertical direction was assumed. An experimental apparatus consists of a plate driven by a voice coil motor, a guide plate with a pressure sensor was prepared. It was shown that the calculation results agree well with the experimental ones.
