<p><P>PROBLEM TO BE SOLVED: To provide a paper delivery device capable of stiffening only a paper sheet necessary to be stiffened, and to provide an image forming device with the same. <P>SOLUTION: A stiffening member 17 is provided with one substantially cylindrical roller 25 opened in one end thereof and the other substantially cylindrical roller 27 opened in one end thereof. The one roller 25 and the other roller 27 are arranged opposite to each other in both open ends thereof. The one roller 25 and the other roller 27 can be moved in the axial direction, and an open end part of the one roller 25 is formed with a plurality of enlarging diameter parts 25b in the circumferential direction, and an open end part of the other roller 27 is formed with a plurality of enlarging diameter parts 27b in the circumferential direction. When the one roller 25 and the other roller 27 are pushed to each other, the enlarging diameter parts 25b of the one roller 25 and the enlarging diameter parts 27b of the other roller 27 are projected outward, and when the one roller 25 and the other roller 27 are separated from each other, the enlarging diameter parts 25b of the one roller 25 and the enlarging diameter parts 27b of the other roller 27 are respectively shrunken to eliminate the outward projection. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
