Paper sheet takeout device

Abstract

A paper sheet takeout device has a mounting base on which a plurality of pieces of mail are mounted in a vertical posture, floor belts partially exposed from the mounting base, a backup plate, a takeout roller and an auxiliary roller. A diameter of a pulley around which a floor belt on a downstream side in a takeout direction of the mail wound is set to be larger than that of a pulley around which a floor belt is wound, and the floor belts are driven by the same floor motor to thereby set a feed by the floor belt to be larger than that of the floor belt.
