Abstract: The invention provides a punching system that has a relatively simple structure to provide an apparatus reduced in overall size and having a low profile, and can produce a high-quality punched hole while conveying a sheet. The punching system includes a punching device that has a punching member moving back and forth perpendicularly to the sheet being conveyed, a frame, and a sheet conveyance mechanism. The punching device is attached to the frame by an attachment unit in such a manner that it is movable in the sheet conveyance direction. The sheet conveyance mechanism includes carry-out rollers that sandwich the downstream end of the sheet at the start of sheet punching motion of the punching member and that are installed at positions downstream from and transversely corresponding to the punching position.
