Separation mechanism

The separation roller [4] is driven to rotate in the opposite direction from the paper transfer direction [2]. When
transferring no or 1 sheet of paper, the separation roller rotates in the paper transfer direction to transfer the
paper to the paper transfer section because the frictional force between the paper feed roller [1] or the paper
and the separation roller [4] is stronger than the frictional force of the torque limiter [3].
When transferring 2 or more sheets of paper, the separation roller rotates in the reverse direction to prevent the
bottom sheet from being transferred because the frictional force between the sheets is stronger than the fric-
tional force of the torque limiter [3].
