<p>PURPOSE:To prevent the generation of curr and reduce the dimension of a copying machine by filling the inside of the supporting shaft of a paper feeding roller with adsorbent and always removing the moisture in copying paper sheets. CONSTITUTION:A supporting shaft 7 for holding a paper feeding roller 6 installed in the upper part on the front side of a paper feeding capsule 5 is constituted of a hollow body whose one edge side is opened, and a plurality of round-hole-shaped ventilating holes 10 are drilled onto the outer wall surface. The inside of the supporting shaft 7 is filled with the replaceable moisture adsorbent 11 such as silica gel, and the opened port part of the supporting shaft 7 is closed by a cap 12. The paper feeding roller 6 is revolved by turning said supporting shaft 7 by a motor, etc., and the uppermost copying paper sheet 9 in the paper feeding capsule 5 is driven-out forward. In this case, the absorbent 11 in the supporting shaft 7 is stirred, and always fresh adsorbent 11 is positioned onto the surface, and the moisture in the copying paper sheet 9 is adsorbed by the adsorbent 11, and the generation of curr of the copying paper sheet 9 is prevented previously.</p> |
