<p>PROBLEM TO BE SOLVED: To circulate and reverse a paper sheet with simple constitution and in a space-saving manner by providing a carrying passage for both carriage and reversing provided with a circulation carrying route to guide a paper sheet on which an image is formed to an image forming part again, roll pairs capable of being rotated in the forward and reverse direction, and a chute for correcting the curl. SOLUTION: A reverse and correction guide part 16 is provided with forward/ reverse carriage roll pairs 15 and a curl correction chute 16a to be curved at the prescribed curvature, and has the function to reverse the face side and the back side of a paper sheet and the function to correct the curl of the paper sheet to constitute a carrying route for circulation. The paper sheet fed into an inlet guide part 12 is fed to the reverse and correction guide part 16 through the route indicated by N. The forward/reverse carriage roll pairs 15 are rotated in the direction P, and the paper sheet is carried downwardly in the reverse and correction guide part 16 to correct the curl. The occupying space can be reduced compared with the case where individual mechanisms are separately provided, and an image forming part can be miniaturized.</p> |
