<p>PROBLEM TO BE SOLVED: To discharge a paper sheet free from heat curl without providing a decurler on the rear stage by providing a curl correction part having a curvature radius regulated to a specified value or less and curved downward on a paper sheet feeding passage. SOLUTION: A reversing discharge passage 13b is branched from the middle of a lead-in passage 13b, and its terminal is merged to an upstream feeding passage 12 in the paper sheet discharge port 11 of a printer 1. A return passage 13 is branched from a feed passage 12 on the paper sheet carrying directional upstream side relative to the lead-in passage 13a by a gate 10a, and the terminal is merged to the feed passage 12 on the sheet sheet carrying directional upstream side relative to an image forming device. The part P of the paper sheet feed passage 12 is curved down with a curvature radius of 30 mm or less to the carrying surface so as to surround the pinch rollers 17a of a pair of discharge rollers to form a carrying passage. The lead-in passage 13a is curved upward to the carrying surface from the paper sheet feed passage 12 by the guide of a gate 10b and branched.</p> |
