<p><P>PROBLEM TO BE SOLVED: To provide a sheet punching device preventing a plurality of sheets from colliding to damage the sheets, while improving productivity by enlarging sheet spacing even when the sheets are discharged from a reverse path or the like of an image forming device body. <P>SOLUTION: The sheet punching device 300 is provided with a sheet detecting sensor S3. Based on a detection signal of a sheet tip by the sheet detecting sensor, before a sheet rear end is separated from the hold of a discharge roller 120 of the image forming device body 101, the carrier speed of the sheet punching device 300 is made higher than the discharge speed of the discharge roller 120 of the image forming device body 101. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
