Abstract

PURPOSE:To surely process paper sheets, stacked on a lift bed, by providing a rotary member which comes into rotary contact with one end part of the paper sheet while moving relatively to the paper sheets stacked on the lift bed. CONSTITUTION:After a paper sheet P is stacked on a lift bed 2, it is lifted by reversing a reversible motor 11 being based on a detection signal, simultaneously by actuating an electromagnetic clutch, a rotary roller 4, while it is brought into rotary contact with one end part of the paper sheet P, is lifted. Here by the rotary friction action and the impulsive action by the rotary roller 4, the end part of the paper sheet P can be effectively processed. Here because the rotary roller 4 comes into rotary contact in the forward direction for the rising direction of the lift bed 2 further with the paper sheet P in a condition that its end part can be brought up freely to the upper, each paper sheet P, while its end part is successively floated, can be surely further efficiently processed.
