<P>PROBLEM TO BE SOLVED: To solve the problem with a conventional device, wherein when a pressing roller is provided at a location corresponding to a hole position of a punched sheet to flatten burrs thereof by nipping and conveying the punched sheet with high pressure, it often results in generating stripes or wrinkles at an end of the pressing roller. <P>SOLUTION: A sheet processing device is configured such that the punched sheet punched by a punching device is introduced into a reversing passage where the conveyance direction of the sheet is reversed, and, while the sheet is being reversed, the punched portion of the sheet is allowed to pass twice through the pressing roller disposed in the reversing passage. With this configuration, it is enabled to flatten the burrs without generating any stripes and wrinkles at the end of the pressing roller, and thus a high quality punched sheet can be formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
