Claims

[Claims for Utility Model Registration] (1) In a paper ejection unit in which paper is ejected to a tray by a pair of paper ejection rollers having a plurality of grooves extending in the axial direction on the peripheral surface of one of the rollers, and the sheets are stacked on the tray. , the above-mentioned groove is composed of a flat surface that extends generally in the radial direction of the roller provided with this groove and faces forward in the rotational direction of the roller, and a flat surface that extends approximately from that plane forward in the rotational direction of the roller and faces outward from the roller. A paper discharge unit characterized by a groove having a V-shaped cross section. (2) The angle α formed by the two planes constituting the V-shaped groove has a relationship of α90° - β, where β is the angle between the paper loading surface of the paper ejection tray and the horizontal plane. A paper discharging unit according to claim 1 of the utility model registration claim, (3) the above paper discharging roller pairs are formed in the shape of a conical surface with respective peripheral surfaces in line contact with each other, and a plurality of sets are arranged coaxially. 1. A paper discharging unit according to claim 1, characterized in that the paper discharging unit comprises:
