摘要： In a paper-punching device (33) for use in an image-forming apparatus, the rear edge of a sheet of paper that is being transported through a transport guide is detected by the photosensor (32). After a predetermined time has passed since the detection, a punching device (33) is activated. At this time, a punching member (38) is depressed downward, and a punching blade (38a) attached to its top penetrates through the sheet of paper, thereby forming a punch hole. Even during the punching operation, transport rollers (34,35) continue to rotate. Therefore, when the sheet of paper is caught by the punching blade (38a), the transport rollers (34,35) are allowed to make a slip at a predetermined amount with respect to the paper. For this reason, at least one of the transport rollers (34,35) is made of a foamed material. With this arrangement, since the punching operation is carried out on the rear side of the sheet of paper, it becomes possible to reduce the occurrence of paper jams even if sheets of paper are transported in succession. Further, the punching operation is carried out while the paper is being transported; this makes it possible to provide a high-speed operation. Further, even if the sheet of paper is caught by the punching blade, it is not damaged because the slip is provided.
