<p>The stacker for a paper sheet counting apparatus of the present invention has a rotatable drum and a plurality of rigid, substantially L-shaped blade members mounted on and around the drum periphery in equally spaced apart relation to one another. Each blade member has one end mounted for limited, free pivotal movement on the drum and its other and extending in a direction opposite to the intended rotational direction of the drum, the pivotal movement of each blade being responsive to rotation of the drum in such manner that the radius of rotation of said radial distance of projection of its other end away from the drum periphery is increased and decreased during rotation of the drum.</p> |
